How to avoid being in trouble with "Analysis paralysis"

2009-11-30T20:12:00.000-08:00

As a Web application developer, I face lots of problems at the same time.

* Some rose all of a sudden

--> which vary as a critical issue or minor issue.

* Some become severer issue in a long term.

--> before the issue was considered a minor issue, but became a critical, difficult issues.

Daily operation, Application users inquiries, enhancements, bug fixes, and above issues.

Have to have all things done but time is limited.

You have to think your responsibility when prioritize tasks you are having in hand.

if you are working in a team and each member is assigned to specific role as a primary responsibility, you decide what to do next according to it.

and then next, if you have limited time but must have some of your tasks done,

you chose what you can put off later.

and decide what you need to do, how much time you can spend on it.

these actions are planning.

Here is the article from eHow.com

Note About Item43.Return empty arrays or collections, not nulls

2008-10-28T21:52:00.000-07:00

The note that I'd like to summarize here is about the method design in Java language and more particularly about the return value when they are either Array type or Collection objects.

It's sometimes argued that a null return value is preferable to an empty array because it avoids the expense of allocating the array.This argument fails on 2 counts.
It's possible to return the same zero-length array from every invocation that returns no items because zero-length arrays are immutable and immutable objects may be shared freely.

For collection, use the following appropriately.

Collections.emptySet();
Collections.emptyList();
Collections.emptyMap();

for array, use the following technique.

(the following example is the case the array type is String)

private static final String[] EMPTY_STRING_ARRAY = new String[0];

Collections.toArray(EMPTY_STRING_ARRAY);

pros and cons of Singleton, Monostate

2008-10-24T22:17:00.000-07:00

In my SCJD assignment, I had to decide how to meet a requirement which was that the meta information of the database should be read only once and reused them on later uses.

For example, in starting up time, the application will read the header information of the database such as the size of the database record, the number of fields, or the length of each field.

and those header information will decide how the data is organized and should be treated when read and write operation. And those header information won't change during the run-time operation which means they are static in the single session.

In java programming language, you could achieve this by several choices explained in the following.

Singleton

pros

Global access point(exactly one instance exists in one JVM)
Cuts the starting up time and memory allocation(Singleton object is instantiated only when the instance is needed(if lazy instantiation is applied))

cons

can't be inherited(because the constractor of the singleton class should be private)

----memo---

1) If the lazy initialization is applied, A Singleton ojbect is initialized at the time when the getInstance method is invoked at first.

2) If the eager initialization is applied, the Singleton object is initialized by a static initializer and in other words, the Singleton object is created before any thread accesses the static Singleton object.

What's the difference b/w 2 cases??!!

--->answer is When JVM loads the singleton class into the memory, the eager initialization applied Singleton class is instantiated, but not for the lazy initialization applied one.

When JVM loads the particular class is at the time of the first occurence of any one of the following.

A class or interface type T will be initialized immediately before the first occurrence of any one of the following:

T is a class and an instance of T is created.

T is a class and a static method declared by T is invoked.

A static field declared by T is assigned.

A static field declared by T is used and the field is not a constant variable (§4.12.4).

T is a top-level class, and an assert statement (§14.10) lexically nested within T is executed.

Refactoring Java codes

2008-09-14T02:00:00.001-07:00

This is obviously very important if you wanna make a software more maintainable and flexible.

I am currently working on SCJD exam. and made brief disciplines for refactoring the SCJD assignment application.

It's because I thought refactoring a software would take forever.

needed to set the goals in respective with the target software.

SCJD application would have to be as much simple as it can be..I felt after reading lots of forum topics on Saloon.

here is my refactoring disciplines.

1.decouple with other class

2.simple logic

3.easily understandable naming given to classes, variables, and methods.

4.follow famous object oriented disciplines (and patterns if you think you can apply without much changes, and giving more complexity.)

Performance improvement of Distributed Application RMI

2008-09-08T03:42:00.000-07:00

Our application in big picture consists of 2 java applications.

One is responsible to handle the users' request for our web system, which is a J2EE application running on Tomcat4.1 corroborated with Apache HTTP Server2.0 and

Another is responsible to play an interface role between AS/400 based application which manages to manipulate the back-end DB and J2EE app.

[figure]

Apache+Tomcat(J2EE) ==> RMI app(J2SE) ==> AS/400 => Back-end DB(DB2)

This is the simplest view of our web system,but major components are all in it.

Why the system architecture becomes like this is due to the historical reason in our project and security as well.

DB2 stores the users' confidential data, item stock data, place order data, and shipment data which all are essential.

and the member in one department in our organization managed it, and J2EE app has been managed by the member in different department.

and things didn't go smoothly at the time of system integration of AS/400 based and J2EE app..

then as a result of that, RMI use was thought and decided to use.

and now what's happened is the performance between Tomcat and RMI is very slow and

at the busy time at around 12am noon to 14pm or so, it responds to each request very slowly.

but we did the following for improving its performance already.

1. Made tables in Oracle indexed organized tables

2. Cached the definite/constant search inquiry results in J2EE app

3. Stored static HTML file and picture file on HTTP server

SCJD exam study

2008-09-06T23:12:00.000-07:00

It has been passing months more than I was expecting to finish the SCJD exam up.

wow, In japan it's limited to make it up within 1 year, that means in my case it should been done by the end of Nov,2008.

I was once wondering how long other exam takers take to finish it up, and searched in google..

Of course that depends on the case of each individual lifestyle, experience, and circumstance.

some guy did in a few months and passed successfully, others didn't finish by spending 1.5 years or more..

but I feel people usually get it done about a half an year, but the result of those are different.

some one got high score of 390/400, someone got 340/400 and so on..

There is nothing to say if you spend the time, you would get higher score...

We can't trust the time spending will make it passed.we need to believe ourselves.

We just need to read and understand the each line in the instruction document, and follow it and make sure your application behaviors are the same as what the instruction says by writing testing source code(Unit Testing) and do the Integration Testing, and user testing..

You wouldn't believe me that I won't get disappointed if I fail the exam, because I learnt a lot and gained so many experience to be a better developer/ a designer..

but I do think so...

probably I have already passed this exam as long as I get satisfied with the experience and knowledge I got haha.That's certainly the one of the primary purpose of this exam.

Now I've gotten already familiar with OO design, Design Patterns, Unit Testing, Concurrency, synchronization,Network communication,Test Driven, and finding the requirement, and decision make on specification.

wow!

Create TSV file with Spool feature of SQL Plus

2008-08-12T23:43:00.000-07:00

To create TSV file of which Oracle DB record data,there is well known way to do so.

SQL>sqlplus -s ${YOUR CONNECTION NAME}

set linesize 500
set trimspool on
set verify off
set termout off
set echo off
set feedback off
set heading off
set pagesize 0

DEFINE DELIMITER='${TAB_SPACE}'
spool tsvfile.tsv
SELECT
COLUMN_A'&&DELIMITER'COLUMN_B'&&DELIMITER'COLUMN_C
FROM TABLE_A;
spool off;
exit;

that's all.
you will see all record data populated from TABLE_A are separated with Tab Space in tsvfile.tsv.

Case:
We are using this simplest authentication method for local connection only.The server this applied are never accessed from Internet user.
You would find this helpful if you want someone to recognize you are care for security risk, and you would probably progress this to better one such as Digest authentication(wiki) or else.

----------------------
1.create password file with using "etpasswd" tool

$htpasswd -c {the absolute path of password file} {user_name}

2.add sample code below to apply basic authentication in config file.

Let's assuming that your path to your password file is in "passwd" directory on document root and file name is "basic_auth_passwd",
"AuthUserFile" parameter value will be "htdocs/passwd/basic_auth_passwd".
and all you have to do is that you put those code below in your preferred "Directory" derective in config file.

[4]Default Transaction concept on Oracle.

Read committed -- This is the default transaction isolation level.
Each query executed by a transaction sees only data that was committed before the query (not the transaction) began.
An Oracle query never reads dirty (uncommitted) data.
Because Oracle does not prevent other transactions from modifying the data read by a query,
that data can be changed by other transactions between two executions of the query.
Thus, a transaction that runs a given query twice can experience both nonrepeatable read and phantoms.

Oracle Tools, Commands, and Procedures

2008-06-19T07:11:00.000-07:00

There are thousands of ways and methods to meet your requirement by useing Oracle Server..and Oracle is keep growing up and will never stop..
Many of engineer regardless of their specific domain of software development, they are eager to catch up a latest techinology and want to be a master of the technology..
You,, if you get tired of catching up, just read this article about Oracle... I just introduce necesarry tools, built-in procedures, and softwares that are all part of Oracle here.
All those are currently used in big E-commerce web system maintenance project.
Not sure those are the best way of handling a problem but certainly can resolve it.

Contents:

Create Database Link
Create Synonym
Original Export and Import Utilities
Create Tablespace
Create User

#DATABASE LINK#
CREATE DATABASE LINK {link_name}
CONNECT TO {user} IDENTIFIED BY {password}
USING '{connect string}';

CONNECT TO clause -- lets you enable a connection to the remote database.
You can specify this clause and the dblink_authentication clause only if you are creating a shared database link.

user IDENTIFIED BY password -- Specify the username and password used to connect to the remote database
using a fixed user database link.
If you omit this clause, the database link uses the username and password of each user who is
connected to the database. This is called a connected user database link.

USING 'connect string' -- Specify the service name of a remote database.
If you specify only the database name, then Oracle Database implicitly appends
the database domain to the connect string to create a complete service name.
Therefore, if the database domain of the remote database is different from that of the current database,
then you must specify the complete service name.

#CREATE SYNONYM#
(http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_7001.htm#SQLRF01401)
CREATE OR REPLACE SYNONYM VOIUSER.TR_VOI_SHOP_SYN_STOCK FOR CHANNEL.TR_VOI_SHOP_SYN_STOCK;

OR REPLACE - Specify OR REPLACE to re-create the synonym if it already exists.
Use this clause to change the definition of an existing synonym without first dropping it.

schema - Specify the schema to contain the synonym.
If you omit schema, then Oracle Database creates the synonym in your own schema.
You cannot specify a schema for the synonym if you have specified PUBLIC.

#19 Original Export and Import#
(http://download.oracle.com/docs/cd/B19306_01/server.102/b14215/exp_imp.htm#SUTIL001)

(1)export command example

#user-mode export example:
exp {user}/{password} file={export file name with extension} owner={owner schema name} log={log file name}

#table-mode export example:
exp {user}/{password} file={export file name with extension} tables=('TABLE_A','TABLE_B',

'TABLE_C') log={log file name}

(file) -- Specifies the names of the export dump files.
The default extension is .dmp, but you can specify any extension.
Because Export supports multiple export files, you can specify multiple filenames to be used.

(log) -- default nono.Specifies a filename to receive informational and error messages.
If you specify this parameter, messages are logged in the log file and displayed to the terminal display.
#where is the log file placed on Oracle running host??

(owner) -- default none.Indicates that the export is a user-mode export and lists the users
whose objects will be exported.
If the user initiating the export is the database administrator (DBA), multiple users can be listed.
User-mode exports can be used to back up one or more database users.
For example, a DBA may want to back up the tables of deleted users for a period of time.
User mode is also appropriate for users who want to back up their own data or
who want to move objects from one owner to another.
#What is Export session in User Mode?
(http://download.oracle.com/docs/cd/B19306_01/server.102/b14215/exp_imp.htm#sthref2558)

(tables) -- default none.Specifies that the export is a table-mode export and lists the table names and partition and
subpartition names to export. You can specify the following when you specify the name of the table:
*schemaname specifies the name of the user's schema from which to export the table or partition.
The schema names ORDSYS, MDSYS, CTXSYS, LBACSYS, and ORDPLUGINS are reserved by Export.
*tablename specifies the name of the table or tables to be exported.
Table-level export lets you export entire partitioned or nonpartitioned tables.
If a table in the list is partitioned and you do not specify a partition name,
all its partitions and subpartitions are exported.The table name can contain any number of '%' pattern
matching characters, which can each match zero or more characters in the table name against the table objects
in the database. All the tables in the relevant schema that match the specified pattern are selected for export,
as if the respective table names were explicitly specified in the parameter.
*partition_name indicates that the export is a partition-level Export.
Partition-level Export lets you export one or more specified partitions or subpartitions within a table.

The syntax you use to specify the preceding is in the form:

schemaname.tablename:partition_name
schemaname.tablename:subpartition_name

If you use tablename:partition_name, the specified table must be partitioned,
and partition_name must be the name of one of its partitions or subpartitions.
If the specified table is not partitioned,
the partition_name is ignored and the entire table is exported.

(statistics) -- default ESTIMATE.Specifies the type of database optimizer
statistics to generate when the exported data is imported.
Options are ESTIMATE, COMPUTE, and NONE. See the Import parameter STATISTICS and Importing Statistics.

(filesize) -- default is OS dependent.Export supports writing to multiple export files,
and Import can read from multiple export files. If, on export, you specify a value (byte limit) for
the Export FILESIZE parameter, Export will write only the number of bytes you specify
to each dump file. On import, you must use the Import parameter FILESIZE to tell
Import the maximum dump file size you specified on export.

(2)import command example

#imp {user}/{password} full=y file=webext1.dmp ignore=y commit=y indexes=n constraints=n log={log file name}

Import parameters
(http://download.oracle.com/docs/cd/B19306_01/server.102/b14215/exp_imp.htm#SUTIL001)

(full) -- Default: y. Specifies whether to import the entire export dump file.

(file) -- Default: expdat.dmp.Specifies the names of the export files to import. The default extension is .dmp.
Because Export supports multiple export files (see the following description of the FILESIZE parameter),
you may need to specify multiple filenames to be imported.

(ignore) -- Default: n.Specifies how object creation errors should be handled.
If you accept the default, IGNORE=n, Import logs or displays object creation errors before continuing.
If you specify IGNORE=y, Import overlooks object creation errors when it attempts to create database objects,
and continues without reporting the errors.Note that only object creation errors are ignored; other errors,
such as operating system, database, and SQL errors, are not ignored and may cause processing to stop.

(commit) -- Default: n.Specifies whether Import should commit after each array insert.
By default, Import commits only after loading each table, and Import performs a rollback when an error occurs,
before continuing with the next object.

(indexes) -- Default: y.Specifies whether or not to import indexes. System-generated indexes such as LOB indexes,
OID indexes, or unique constraint indexes are re-created by Import regardless of the setting of this parameter.
You can postpone all user-generated index creation until after Import completes, by specifying INDEXES=n.

(constraints) -- Default: y.Specifies whether or not table constraints are to be imported.
The default is to import constraints.
If you do not want constraints to be imported, you must set the parameter value to n.
Note that primary key constraints for index-organized tables (IOTs) and object tables are always imported.

(log) -- Default: none.Specifies a file to receive informational and error messages.
If you specify a log file,
the Import utility writes all information to the log in addition to the terminal display.

some tips examples:
1) Import an exported file to as different user.
#imp --- fromuser={old_user_name} touser={new_user_name}

(fromuser) -- Default: none.A comma-delimited list of schemas to import.
This parameter is relevant only to users with the IMP_FULL_DATABASE role.
The parameter enables you to import a subset of schemas from an export file containing multiple schemas
(for example, a full export dump file or a multischema, user-mode export dump file).
Schema names that appear inside function-based indexes, functions, procedures,
triggers, type bodies, views, and so on, are not affected by FROMUSER or TOUSER processing.
Only the name of the object is affected. After the import has completed, items in any TOUSER schema
should be manually checked for references to old (FROMUSER) schemas, and corrected if necessary.
You will typically use FROMUSER in conjunction with the Import parameter TOUSER, which you use
to specify a list of usernames whose schemas will be targets for import (see TOUSER).
The user that you specify with TOUSER must exist in the target database prior to
the import operation; otherwise an error is returned.

(touser) -- Default: none.Specifies a list of user names whose schemas will be targets for Import.
The user names must exist prior to the import operation; otherwise an error is returned.
The IMP_FULL_DATABASE role is required to use this parameter.
To import to a different schema than the one that originally contained the object, specify TOUSER.

(indexfile) -- Default: none.Specifies a file to receive index-creation statements.
When this parameter is specified, index-creation statements for the requested mode are extracted and written
to the specified file, rather than used to create indexes in the database. No database objects are imported.
If the Import parameter CONSTRAINTS is set to y, Import also writes table constraints to the index file.

#Create tablespace#

(logging_clause) -- (http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/clauses005.htm#i999782)
The logging_clause lets you specify whether creation of a database object will be
logged in the redo log file (LOGGING) or not (NOLOGGING).

#create user#
(http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_8003.htm#SQLRF01503)

(Quota clause) -- Use the QUOTA clause to specify the maximum amount of space the user can allocate in the tablespace.
A CREATE USER statement can have multiple QUOTA clauses for multiple tablespaces.
UNLIMITED lets the user allocate space in the tablespace without bound.

(Account clause) -- Specify ACCOUNT LOCK to lock the user's account and disable access.
Specify ACCOUNT UNLOCK to unlock the user's account and enable access to the account.

JVM Performance Tuning in real world

2008-06-04T15:29:00.001-07:00

Suprisingly, No one have interest in how fast the running application is and where would be bottle neck of performance in it..
I have been involved in maintenance project of E-commerce website such as like Amazon.com for past 4 months.. and have become very suspicious about they, maitenace guys don't try to collect the data of performance... called benchmark...

It's just because the application runs within the limit of maintenace guy's in mind.
and only if their boss get recognized by calling or emailing by the end-users that say application is too slow to use,, they would start analizing the bottle neck or collecting bench mark data...

I was wondering how the other guys think of performance importance of running application from maintenance guys point of view...

well, but I was feeling about collecting perfromance data is right thing and key work to do, I trid to know and evaluate application performance...

Making java J2EE application runing faster

2008-04-23T07:58:00.001-07:00

My current project, application is running on JVM 1.4. and they are eager to improve performance.
but I have thought why they get it replaced with later version above 1.4?!

and by observing the coding, programmer didn't understand what each of collection class is for? and purposes..

and such thought came on me in my family...
my mother asked me if she can install Office XP into Windows Vista OS.

I searched by google and found this site..

1.The Really Big Index
A list of all content pages in the The JavaTM Tutorial

***JTable***
In SCDJ assignment, explicitly mentions that the search result data must be rendered into JTable which is part of Swing Component.
And because of flexible design of swing component, in other words, it provides various ways of table implementation. so that Designer has to be considering which way would meet a requirement the most.

Problems that I have had.
1. getColumnClass() method throws an nullpointerexception on my table model class.
--> tablemodel getcolumnclass() method produces null pointer exception

***JFrame***
1.I wanted JFrame to get repainted by invoking repaint() on it, but JPanel object with it hasn't been repainted..
---> to understand a fundamental of paint mechanism Painting in AWT and Swing
After I had read some discussion on forum.sun.com, I knew how I achieve.
---> the search result with my search criteria.

the following is the source code snippet.
use JFrame.validate().


public class BaseWindow extends JFrame{
private JPanel mainPanel;

public Basewindow(){
initComponents();
}

private void initComponents(){
// set up components and add into JFrame.
}

public void setMainPanel(JPanel jPanel) {
System.out.println("BaseWindow.setMainPanel()");

if (mainPanel instanceof SearchResultScreen) {
System.out.println("this is SearchResultScreen");
}
if (mainPanel instanceof InitialScreen) {
System.out.println("this is InitialScreen");
}

this.remove(this.mainPanel);
this.mainPanel = jPanel;
this.add(this.mainPanel);
this.validate();
}

***JTextField***
oh, It got stacked by formatting a pair of a label and corresponding text field.
Here what I wanted to do was to place a pretty ordinary pair on JPanel that
was "search:" label and corresponding search text field that a user can enter a 
criteria in it.

The problem was come from misunderstanding of JTextField.setColumn() specification.
I thought it didn't affect textfield width, and I defined it by giving 200 as column size.
and I also defined both width as the following.

laName.setPreferredSize(new Dimension(100,25));
tfName.setPreferredSize(new Dimension(400,25));

My screen always came up in unwanted/unexpected layout because I exptected those width defined
by a setPreferredSize argument.But it's not..
Then I searched similar problem and even debugged my code for hours and
finally knew that unexpected layout was because of misuse of setColumn().
so after I deleted setColumn() code and only use setPreferredSize()
my layout is looking fine and that exactly what I wanted it to look.


***I/O Handling***
Hove to choose an appropriate way of handling I/O DB file in an assignment.
and for understanding the fandamental I/O in Java,
do read this tutorial first.

Lesson: Basic I/O
Top Ten New Things You Can Do with NIO
Conventional & Interruptable IO - Reading large files -- use FileChannel or BufferedReader?

***Handling a binary file in Java***
Hexadecimal - Wikipedia, the free encyclopedia

I have to parse a binary data file and store in memory and search with given criteria in it.
and must take place in fastest search!
so I am wandering what kinds of parsing a binary data file could be fastest?!
I need to learn some basics about data manuiplation in Java.. do read some discussion board and consider..
Java Programming - Parsing binary file- unsigned longs


***Flexible Search Mechanism***
The Exam clearly mentions that the application search must be applied of flexible search
mechanism, but don't even say what is flexible and not.
So I tried and looked at some discussion on this ambiguous description of a specification.
Here you can see other's opinions on it here.

After I have read above discussion, I knew "flexible search mechanism" implies on a feature for application user,
then doesn't mean that flexible search algorism in terms of programming ways...

The key points that I have to accomplish are application search has to be flexible and fast.
To know how search could be faster in Java, you can check out this apache project and
some other discussion boards on forum.sun.com.

Apache Lucene

Java Programming [Archive] - Any Ideas For a Fast Search Engine?
Data structure for fast search within large text
Collections: Lists, Sets, and Maps - fast searching

I knew some keywards of search methods by reading disucussions.

Fastest is by hash O(1),
then comes binary search O(log N),
and finally linear search O(N).

@Op. Google on Boyer-Moore string search. It's a very fast search algorithm.

Architecture of Apache-Tomcat connectivity,port number and protocol

2008-04-14T16:21:00.000-07:00

We often follow a server configuration without understanding its concept and how it works.
This practice would bring you a problem. for example, if any problem occure related to it, you can't figure out the real/root cause...
Only when you know how it works, you can check steps what you have configured and what it is supposed to be, again otherwise you will never find a problem cause.

MVC Patturn in J2SE and J2EE

2008-04-04T05:06:00.000-07:00

This term is very famous with people who have been working as Web application developer and have used J2EE technology. Because This term is explained in all books which new J2EE developer generally read.
And such guys will write source codes based on Spring or Struts Framework which force you develop application applying the MVC pattern.

My doubt comes up at this time like,

"well, View can be anything for example Swing or HTML, How can I switch to Swing from the HTML view originally developed as J2EE application??"

And When we look at the Swing source code and learn some basic concept and write some example small application copied from Sun Tutorial, start wondering

" Is it possible to just switch the view without changing anything on the controller and model?! I am really wondering if we would work a bit hard to adapt the Controller source to Swing View? or even the Model?!?!"

Well, if any of you have same doubt or currently struggling to figure out the difference(in practice) of the MVC use in J2EE and J2SE application..

Look at this for studying J2SE MVC use Article.

Another guy was once clueless about the difference b/w J2EE MVC and J2SE MVC.
look at this discussion board thread.

This may be also a worthy technical article for a guy who is clueless.
--> Advanced Model-View-Controller Techniques

***MVC Version list***

MVC version1.0
MVC version1.5
MVC version2.0 -- well known MVC version an application is divided into 3 parts(Model,View,Controller)
Modifying MVC version2.0 (above sun.java article introduces this concept and other framework also follow this architecture for instance, Apple Cocoa, J2EE Framework(Struts..))

Debian Linux

Network configulation on Debian.

Debian Reference
Chapter 10 - Network configuration

*Packages*
While configuring Gnome-gcc package, error came up as below.

"checking for C compiler default output... configure: error: C compiler cannot create"

But one idea came up with which is to install using a deb file(its extension is .deb).
By executing the command like,

$dpkg --install [your desired debian file whose name ends with ".deb"]

-->you can refer for more information here (http://www.debian.org/doc/FAQ/ch-pkgtools.en.html)

It will automatically extract and place at correct folder location.
If there is a deb file available with preferred package version, better use a deb file rather that compiling and installing from source files.

Here you can look up your desired package focusing on debian.

***Install gnome-ppp***
An install program ended while installation with showing error cause,

"gnome-ppp depends on wvdial; however : Package wvdial is not installed.

okay I went on installing wvdial first, and then I got following error details when wvdial installation failed.

"wvdial depends on ppp,
***,
wvdial depends on libuniconf4.2,
***,
wvdial depends on libwvstreams4.2-base,
***,
wvdial depends on libwvstreams4.2-extra,
***,
wvdial depends on libxplc0.3.13"

aaahh!! I got to install 6 packages for installing gnome-ppp!! and now I don't even know how many more required packages have to be installed for installing those 6 packages...
could be 10 to 20 packages...

haa..

I avoid installation nightmare and decide to use "Synaptic Package manager" with debian installation CD-ROM.
By using its manager tool,I can select and download a desired package(If it's available in CD-ROM) from CD-ROM without bothering package dependency!!

***Watching a DVD***
When I inserted a DVD and then tried and ran, this message came up,

"The source seems encrypted, and can't be read. Are you trying to play an encrypted DVD without libdvdcss?"

huh,,,Always Linux has to be set up something when try to something new..
and makes us frastrated...but I know through setting up and figuring out a problem cause on Linux, some people are having fun! (like me?!)
anyway, I will have to start figuring out the problem cause of DVD watching failure..

I just googled with above error message and found usuful instruction on this and solved a problem. All you have to do is just follow an instruction on there!!

***Language setting***
Mainly my partner need to input Japanese letter on Linux , so that I need to install for allowing us to input Japanese language.
and found this package Language-env and his package allows not only Japanese , but Korean,Chinese, (Tamil?! not sure) French and further more!

Ubuntu Linux

2008-03-30T08:06:00.000-07:00

I have been using several types Linux Distributions for example,,, FedraCore,RedHat,Debian...
and then now I decided to use Ubuntu Linux...
The reason why I chose is the Ubuntu has been making progress very fast that is like no other distributor does...And from Ubuntu wikipedia page I knew founder has great sense of progressing open software. I don't wanna spend my time on the one which in the future no one uses,, I wanna use it becomes more famous and well-developed...I bet Ubuntsu will go on greatly..
I hope...

Monitor Your Tomcat Application Memory use on JVM

2008-03-06T02:41:00.000-08:00

Our application has a batch job included inside, it is called TimerTask.
And For be sure to know how much it affects memory use, We got to monitor JVM memory when the job runs.

Above Java5.0, Java SDK includes a monitoring tool itsefl called Jconsole.

here are some useful reference pages that I saw while I went on

How to use jconsole, what is jconsole, how it works, what we can do with it...

here is my case..
I need to monitar a tomcat application..

I opened startup.bat and added the following in just before calling catalina.bat line inside..

set JAVA_OPTS=-Dcom.sun.management.jmxremote=true

then open command prompt and run startup.bat then after execute jconsle command from same command prompt window.. that's all..

you will see tomcat application in jconsole window!

There are lots of J2EE Application development technologies&tools on the earth but we know only a few of those...

2008-03-05T00:41:00.000-08:00

In Japan and India, People tend to use Tomcat+Apache+JavaSDK technologies for developing J2EE application. and IDE is Eclipse...
then when the application becomes a product version, we simpliy change servers that are Tomcat+Apache to WebLogic/WebSphere if we need higher performance and more reliability.

It is because when they were new beas, those techs were poplar and lots of study material in bookstore and Internet articles..and they were lighter from performance perspective than other application server..

Java technologies cover more and more in various fields.
You could know just you access Sun website and says and introduces lots of teshs..
NetBeans<==>Eclipse
Tomcat<==>GlassFish
Oracle,PostgreSQL...<==>MySQL(it finally became part of Sun!!)

Most of java developer know a lot of about Tomcat, Eclipse and several Apache foundation tools and something about Database side (i.e.Oracle) in Japan,India.
But that's all..

To tell all of you the truth I am also one of that kind guy.... but I just wanted to know other part in Java technologies.
such as, GlassFish application server, javax.activation package(part of J2EE), JAXP..related to WebServices(like Axis)..

There will be a lot of fun and new world for those developers.

Parsing XML quick learning with sample code

2008-03-04T04:33:00.000-08:00

Hi, I got a need to learn how to parse a xml file in java, Actually I used and did same things 3 years ago, that time I used othar libraries(Xalan, Xerces) provided by Apache project. but this time I try and use part of the standard development kit of Java 6.0. that part is called JAXP.

Requrements:
My need with a XML parsing library is
1.load a xml based configuration file(i.e. server.xml for Tomcat)
2.update from a Swing based application

Steps:
For achiving this, what I am going to do with JAXP is looking at JAXP home website and know its overview and goals.

mod_rewrite-Apache HTTP Server
I got some task to improve search engine ranking of our E-commerce website.
then one guy who has big influence a meeting decision was encouraged to use mod_rewrite module, then change our visible URL to user
from
somewebsite.com/somewebapp/paraa-11_parab-22_parac-33.html
to
somewebsite.com/somewebapp.do?paraa=11&parab=22&parac=33

We are completely not sure how much it will work and bring us great success, but we will probably implement this URL rewritting feature..

I tried first with Apache 2.0 for Windows OS but I got a ploblem.

I don't know why so we will try with same configuration on Linux OS. then I will see..
but if we succeed with Linux, another wonder that I will come up with is why I failed using mod_rewrite tool..

[don't work]

RewriteRule ^/aaa/alice.html$ /aaa/bob.html

alice.html and bob.html both are located in aaa directory.
and also I can display sending those requests through IE("http://localhost/aaa/alice.html", "http://localhost/aaa/bob.html").

Handling "mutually exclusive access" in Java for Enterprise application use

2008-02-24T07:10:00.000-08:00

For all enterprise application developer in Java, We have to handle an Handling "mutually exclusive access". This requires when we are going to change/update data state of DB or variables in software. In a DB part, usually DB server takes care of and will throw an exeption when we violate data state consistency.. but for a variable part we need to do ourselves...

Research: Serialization in Java

2008-02-20T06:38:00.000-08:00

I've gotten some questions related to Serialization concept in Java.Here are the questions as follows.

Purpose:
"The purpose of Serialization in Java is to persist an object for future use or need from other network place."

I understand the serialization is often used when we need to have a persisted object in software.What is its responsibility come in the persisted object concept?! Without serialized object, can't we make an object persisted?
A serialVersionID is used when we need to maintain serialization compatibility between versions( Each class object has its version and it will change when any class members change.But how will it be generated when we don't define it explicitly.

=>A1. We can, with Database server or file in general way.And an object serialization concept obviously has unique advantage that is you can use exactly same object on any JVM.
In other persistence ways, they just hold data persistently and here serialization in Java hold not only data but also the object which is holding data.

Problem1:
First of all, I had the following exception, and immediately see the exception description on java api document online.

java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.io.InvalidClassException: ClassA ; local class incompatible: stream classdesc serialVersionUID = 204317070979582118, local class serialVersionUID = 5826146587350558648
at Someclass.somemethod()...

and guess the cause which is serialVersionUID is different from an object transfering from RMI server..
But I did first time to an object on client machine JVM to declare an long value has same serialVersionUID of RMI server object, but it failed..
Because server object's UID has been generated by JVM, which means it wasn't declared explicitly on that object..

my client object UID wasn't compared with server's..

so I ask management team leader to replace server object to declare UID explicitly and my client object has same one.

then this problem has gone in an air!!

3:
An object is marked serializable by implementing the java.io.Serializable interface,
which signifies to the underlying API that the object can be flattened into bytes
and subsequently inflated in the future.

1:
To wit, when we create an object with the new keyword, the object's constructor is called only when a new instance of a class is created. Keeping that basic fact in mind, let's revisit our animation code.

1:There is, however, a strange yet crafty solution.

grammar:Notice that both methods are (and must be) declared private, proving that neither method is inherited and overridden or overloaded.
grammar:So, even though those specialized private methods are provided, the object serialization works the same way as far as any calling object is concerned.

Log4J logging software

2008-02-11T09:08:00.000-08:00

Log4J -- well known logging library
Log4J Ver. 1.2 API

before decide to use logging, We got to do several things..
1.decide the log level policy.
It has 6 levels to be assigned.
you should define in your project, what log level represents what information.

1.fatal
2.error
3.warn
4.info
5.debug
6.trace

Surely it looks very strange if you define the unexpected system error log is assighed as debug log level.. So you'd better categorize all possible error and desired information outputed in log file and assign the log level meaningfully and acceptably..

Here is the one that we define in my current project...

All we wanted to do with Log4j is as follows.
1.Create and place log file with current date in the specified directory where is in working directory.
=> log file with current date means if run the software for 5 days everyday, we got 5 different log files. so we can easily study and analyze when a particular error occurs. (but I feel if logging information is less amount, you'd better have all in a single log file so that you can only open and study one file. If we have log files by date category in a single directory, when we access that log directory issued with "ls" command, it displays bunch number of log files with different date in it. then for looking for a specefic log file, we again have to issue other command like "ll | grep 08020" or kind of it for displaying only some logs in periodic term.
=>the reason why we wanted log files to place in the specified directory where is in working directory is we thought of future directory structure change.
our desired log file location is in the following directory.

working directory/logs/{here we have all log files}

Loggers,Appender,Layouts are key classes in Log4j software classes.

Logger class has important methods that are listed in the following.


package org.apache.log4j;

public class Logger {

// Creation & retrieval methods:
public static Logger getRootLogger();
public static Logger getLogger(String name);

// printing methods:
public void trace(Object message);
public void debug(Object message);
public void info(Object message);
public void warn(Object message);
public void error(Object message);
public void fatal(Object message);

// generic printing method:
public void log(Level l, Object message);
}

You can define a prefered level to each logger but all logger inherits Root Logger whose level is assigned Leve.DEBUG by default but you can set yours yourself.
(You can find this note in log4j online manual page==>Note that by default, the root logger is assigned to Level.DEBUG.)

Appender class has responsibility of allowing a user to define where a log is outputed, to detail more, Log4J has appenders exist for the console, files, GUI components, remote socket servers, JMS, NT Event Loggers, and remote UNIX Syslog daemons.

So In my case I need to output in files, and for the purpose of improving implementation productivity temporarily, and console. so for specifing the destinations where log is outputted we have to configure appender class to be given to a logger through calling the addAppender method on it. And more over If you wish to custermize the output format, you just need to associate a Layout object that you configure with an appender object.

But simplify all your configuration, you just write a configuration file and load it from the start point of your application where would be initialization method.

imagine this init() metho is loaded just at one instance after your application has started up.


init(){

DOMConfigurator.configure(System.getProperty("user.dir")+"\\logs\\log4j.xml");

}

We can have a configuration file in either properties or xml.
I decided to be in xml. you can refer xml configuration format example here(http://wiki.apache.org/logging-log4j/Log4jXmlFormat).

Please look at the following log4j.xml sample.

oh, How can I paste and display XML code here?!
Does Blogger prohibit displaying XML code?!
==>03.03.08 I could display XML code in blogger.All I have done was to convert <> special characters to HTML entities.

Linux/Unix Command

2008-02-06T16:22:00.000-08:00

This post tells you some useful Linux/Unix Commands.

References:Alphabetical Directory of Linux Commands

$rsync

rsync [options] sources dest
Transfer files; used frequently for updating files across a network. File transfer with rsync is fast and efficient because it checks local files against remote files in small chunks, or blocks, and transfers only the blocks that differ between the files.

$man logrotate

logrotate is designed to ease administration of systems that generate large numbers of log files. It allows auto-matic rotation, compression, removal, and mailing of log files. Each log file may be handled daily, weekly,monthly, or when it grows too large.

Funny usage that I found is someone uses "logrotate" tool for handling CVSroot folder management.

/home/someuser/folderA/cvsroot
.tar.gz {
notifempty
missingok
}

***setting up cvs server and manage cvs account***

1. install cvs package.

$pkgadd -d

2. make sure PATH variable includes the cvs executable file path.

$set

3. create a group for CVS user and change cvs files group owner to "cvs".

$groupadd cvs
$chgrp cvs /{somewhere}/cvsroot /{somewhere}/cvsroot/CVSROOT /{somewhere}/cvsroot/CVSROOT/*

4. create a Linux system user(called "cvsuser") for a CVS user and grouped in of a cvs group.

-->create a user
$useradd -m -d {new user's home directory} -g cvs cvsuser

references:
-m "Create home directory for new user account"
-d "This option specifies the users home directory.If not specified, the default from /etc/default/useradd is used."
-g "The group name or number of the user's main group.The group name or number must refer to an already existing group.If not specified,the default from /etc/default/useradd is used."

-->set up a "auto_home" file
$touch /etc/auto_home??
$vi /etc/auto_home
cvsuser sunblade2:/export/home/cvsuser

-->change the "cvs" user's password setting in /etc/passwd by hand
$vi /etc/passwd
cvsuser:x:503:101::/home/cvsuser:/bin/sh

5. add a cvs user
$cd /{somewhere}/cvsroot/CVSROOT
$/usr/apache/bin/htpasswd -c passwd {$user name}

reference:
-c create a new file

-->create cvswrapper file under $CVSROOT/CVSROOT directory.
$vi cvswrappers
*.gif -k 'b'
*.jpg -k 'b'
*.jpeg -k 'b'
*.class -k 'b'
*.jar -k 'b'

reference:
"cvswrappers" file is...
"If the file $CVSROOT/CVSROOT/cvswrappers exists, any file whose names match the specifications in that file will be treated as packages and the appropriate filtering will be performed on the file/directory before being imported. see node wrappers' in theCVS manual."

The cvswrappers file discription is here(http://cvsman.com/cvs-1.12.12/cvs_183.php).

-k "keyward expansion" this option value can be 'b' for specifing a file data type as "binary".

6. configuration of starting up the cvs server as part of the inetd service.
-->activate cvspserver service in "/etc/inet/service"
$vi /etc/service
cvspserver 2401/tcp # CVS Server

-->add its configuration in /etc/inetd.conf
$vi /etc/inetd.conf
cvspserver stream tcp nowait root /usr/local/bin/cvs cvs --allow-root=/data/cvsroot -f pserver

-->restart inetd
$pkill -HUP inetd

references:
$man pkill
"NAME pgrep, pkill - look up or signal processes based on name and other attributes..."
-HUP "(Hang UP) to tell a program a specified proram hanged up and need to get restarted.so obviously it causes the program to restart."

FTP:
Essential ftp Commands
ftp(1)

Compress directory and transfer to remote machine at one time by shell programming.

* auto_transfer_backup.sh

1.tar zcf A B
2.ftp -n < somewhere/ftp_commands.txt

open $remote_ip
user $username $password
bin
prompt off
cd $remote_dir
lcd $local_dir
put cvsroot.tar.gz
quit

Reference:
prompt-Toggles interactive prompting.
Interactive prompting occurs during multiple file transfers
to allow the user to selectively retrieve or store files.
By default, prompting is turned on.
If prompting is turned off, any mget or mput transfers all files, and any mdelete deletes all files.

binary-Sets the “representation type” to “image”.

ftp> binary
200 Type set to I.
ftp> bin
200 Type set to I.

ftp> ascii
200 Type set to A.
ftp> asc
200 Type set to A.

ftp> prompt -h
usage: prompt [ on | off ]

CRONTAB:

Run a particular program(i.e. shell programming file) at every fixed time.
By the way, we can control specified user access by using /etc/cron.d/cron_deny or cron_allow.

--
A crontab file consists of lines of 6 fields each.
Each of these patterns can be either an asterisk (meaning all legal values) or a list of elements separated by commas.An element is either a number or two numbers separated by a minus sign (meaning an inclusive range).

1st field - minute (0-59),
2nd field - hour (0-23),
3rd field - day of the month (1-31),
4th field - month of the year (1-12),
5th field - day of the week (0-6 with 0=Sunday)
--

(i.e.)
when you want to run a command at 6am on Sundays and standard output and standard error go to a empty file, which means go into the air!.

0 6 * * 0 ${command or shell file path} /dev/null 2>&1

Reference:
/dev/null 2>&1
$man bash and go to see "redirection section".
http://www.xaprb.com/blog/2006/06/06/what-does-devnull-21-mean/

http://en.wikipedia.org/wiki/Data_sink
http://blogs.sun.com/chrisg/entry/who_or_what_deleted_dev

The word following the redirection operator in the following descriptions, unless otherwise noted, is subjected to brace expansion, tilde expansion, parameter expansion, command substitution, arithmetic expansion, quote removal, pathname expansion, and word splitting. If it expands to more than one word, bash reports an error.Note that the order of redirections is significant. For example, the command

ls > dirlist 2>&1
directs both standard output and standard error to the file dirlist, while the command

ls 2>&1 > dirlist
directs only the standard output to file dirlist, because the standard error was duplicated as standard output before the standard output was redirected to dirlist.

2008-01-31T06:37:00.000-08:00

Nowadays people such as a software engineer put their profile and skill-set on Internet and they even don't pretend to keep in secret those information...
Because they expect somebody like HR department guys finds it and they wait for a call/an email from HR...Further more they like their name to be more known by more people in all over the world..

I was hesitate to put my profile or any informatin that can identify who I am on Internet, but those big stream has changed my mind...

So I've decided to put some experience or my consern/interest related to software development here on Blogger blog...

Yaari! sent an invitation mail to all my friends list by accessing my gmail account without my permission!!

2008-01-28T08:16:00.000-08:00

id="BLOGGER_PHOTO_ID_5163081753596866386" />
Just couple of days before, some friends that I haven't heard from for a while suddenly sent me an email and he was just inquiring if I sent him an Yaari! invitation.
He said that looked like spam...

I replied and said that was not mine and asked him ignored it.

I can't just believe the SNS website took user's email lists and use them in our back...

I also was wondering there would be others who have same problem and looked up those people in a net.
and yeah, there are many...

the following URSs are just other cases..

・yaari.com gained access to my contact database

ODesk Assignment No.1: Emailing tons of News Letters every month.

2008-01-11T00:44:00.000-08:00

Assignment:

1)Send a HTML based News Letter to client's customers that is currently about 2,500. in the future it would increase to over 10,000.
2)If we will get bounced backs, put them into a list and eventually make a bounced back list.

My approach:

1) Write a java based software to send them all automatically(like,,,Read recipient's email from Excel and send news letter to it automatically.)So that nobody will get involved in routine, monotonous, and repetitive work! The email addresses are loaded from provided excel file.
2)If we have gotten bounced back, it will change the background color of particular cell where email address is put in excel file.
3)==>02.02.08:SMTP server we have used set Daily Sending Quota on our account,we are not sure it is set initially or set in between, we could send out only limited number about 500 in gmail, 250 in our DSL provider account. All we have to do in this talk is sending out 10,000 mail as soon as possible.
we decided to use 6 or 7 DSL provided account to send out.Each set 250 limitation, we could only send out 1,500(6*250) per day, we need 7 days to complete 10,000 sending(7*1,500=10,500).Software obviously need to be extended to handle this specific situation
(Since we have been using DSL smtp server, the limitation setting on our accounts is out of our hand unless we have our own SMTP server..) So we need some feature for solving this problem.My basic idea is An user can type and save a valid DSL account info as many as possible they can and when we launch software, it loads that account info file and keeps in (its memory space.) and picks up by ordering in a file and uses it for sending out, IF the specific exception occurs that is of cource "Daily sending quota exceeded", changes DSL account from an account that already exceeds daily quota and continue sending.
Software will stop only when there is no more valid DSL account in a file.
4)==>27.02.08: We need to extend our software to have "forward" feature. and only differences between "forward" and our new feature are we need to correct "subject" and address in "To".

"Be effective!"

Issues&Solutions

Issue1:
Error I got from Gmail ==> Daily sending quota exceeded
----
Exception in thread "main" com.sun.mail.smtp.SMTPSendFailedException: 550 5.4.5 Daily sending quota exceeded. f55sm8668781pyh.28
----

Solution1:
1.Search result of this quiery(Daily sending quota exceeded)

(We haven't gotten any solution yet, so my alternative way is to use ISP provided mail account to send news letter out..
Or we will stand with that mail quota limit and send a few hundreds mails day by day till complete sending all.)
==>27.02.08:we discussed and decided to use several ISP provided accounts, let's say, for example use 6 ISP accounts which every account restricted with daily quota limit about only 250 mails per day, but in total we could send out 1,500(6 * 250) mails per day.also decided not to use gmail because gmail smtp server eventually gives our mail back with uncertain error(PERM_FAILURE)...We tried and looked for a solution for it but nothing gives

Issue2:
PERM_FAILURE:SMTP Error (state 13): 550
Suddenly I got baunce backs mail from most of recipients that sent my newsletter to using Gmail account, they actually didn't create any problem last month emailing newsletter...
So I got to find the reason and its solution for proceeding my emailing task..

Solution2:
1.Search result of this quiery(SMTP Error (state 13): 550)

(We haven't gotten any idea to solve this yet)
==>27.02.08:we gave up using gmail account for sending our newsletter out.

Issue3:
The contents of the News letter is made using MS-word and is sent using MS-word feature that is you can select "send to" option from File menu or sort of it. This is the way a HTML news letter made. But Due to MS-Word HTML generator is not well-performed enough, when we try and get an original HTML code from a HTML newsletter, HTML code is broken. This fact leads another problem that is the allighment and format of our newsletter sent by our software are collapsed.
So I need to skip one thing that is parsing a newsletter into HTML code.
and directly send a newsletter without parsing it or getting an original HTML code from a newsletter.

(current procedure)
1.receive a HTML newsletter sent through MS-word.
2.parsing it into HTML code using ,for example if you use gmail "show original" option from option menu in gmail.(<==this step should be skipped.) 3.copy and paste HTML code in our software. 4.send out (<==No.3&4 steps should be skipped.because it collupses HTML format&allingmen.)

(required procedure)
1.receive a HTML newsletter sent through MS-word.
2.send out recieved mail just as it is, only correct "subject" and address in "To".
it is almost same feature of "forward" function.

Solution3:
1.Search result of this quiery(SMTP Error (state 13): 550)

(We haven't gotten any idea to solve this yet)
==>27.02.08:we gave up using gmail account for sending our newsletter out.

Other errors I've gotten:
1. javax.mail.AuthenticationFailedException: Your mail spool lock busy.

First Assignment on ODesk!

2008-01-09T20:44:00.000-08:00

I got first assignment on Odesk, It was started from on 8th, Jan!

Before I become the one who works on that assignment, I already analyzed how I will work on and solve most issues.

So I was very happy with working on and didn't need to waste my analysis time.

overall Assignment description is to email a news letter to bunch or
client's customers( in generally called subscriber).
I need to finish making a software to send it to all of them.
otherwise I got to send it manually taking tons of time!

Opening an US bank account from offshore place

2008-01-04T08:21:00.000-08:00

This is obviously one of the headache that the payment options what freelancer has to choose.

Odesk freelancers are now having 3 options to get Odesk work payment into their pocket.

1.Online bank account
2.US bank accont
3.Odesk credit card

100% sure that all freelancers wish to have a US bank account to get 100% payment without paying any service charge.
But in real many freelancers are living in other countries and which means they don't have it but are eager to have it though.

This idea is only applyed to the freelancers who are living in Japan.

Idea:
By using MJFG service(Your Domestic bank), open the US bank account(Union Bank Of California) for free!!

You have to look at and fill up this form(Form W-8BEN)(PDF) if you are non-US residents.

But there would be similar option that you could open it in your country.Better check it out instead of paying service charge doing nothing!

It is 100% worth to read it out!

Javamail desktop application

2008-01-03T04:50:00.000-08:00

Javamail desktop application

As you know the Javamail API produced by Sun, If we try and make a mail client application, first we would come up with Javamail.
Javamail
-- Javamail home web site(java.sun.com)
-- Javamail FAQ(java.sun.com)
-- Javamail online traininig(java.sun.com)

http://java.sun.com/developer/onlineTraining/JavaMail/
Now I got an assignment from ODesk that is to send a HTML newsletter to numerous number of recipients(like 1,000 to 15,000) with different recipient name on the top in a HTML body.
and also they wanted me to do same job repeatedly, I guess it will happen in every month. Because newsletter which they sent me has a title includes "December, 2007".

So what I thought to complete this work is to let an application complete mailing a newsletter task.
Before we dealt with, I suggested my solution of what an application does the task and they accepted.

I thought that time I could save one person from working on the boring task that sends hundreds of mails manually by automated and productive idea.

This is my main source of energy for working on that task.

So, now I have to make a HTML newsletter sender application in a short time basically based on JavaMail API.

Here is my tasks that I have to proceed and broke it into small pieces.

---Tasks what I am supposed to do for my ODesk assignment---
1.1.Make sure how to send a mail using gmail account by javamail based desktop application.
+--Javamail using Gmail SMTP 465 port!(forum.java.sun.com)--It has a real and workable sample source snippet. You can very easily copy-paste it and test how it works.

1.2.Make sure how to send HTML newsletter via Gmail account mail server using javamail desktop application.
+--How do I send HTML mail?(java.sun.com)--This is part of Javamail FAQ page and it says that sendhtml.java is all prepared to show how to do by sun.com as a demo application bundled with Javamail package.

1.3.Make sure how to send a HTML news letter includes multiple images embedded using Javamail API.
+--How can I create an HTML message which will contain multiple images?(jGuru)

2.1.Figure out, identify, and decide what the application has to do or in other words, what my client wants it to do.
2.2.Use and make sure the features of a sample desktop application bundled with javamail api package with gmail account
3.Take out unnecessary features and added necessary's.
4.Test it out if it works as my client expects what it has to do by testing manually and automatically.

How is this plan I set up?!
Does anybody figure out the missing tasks what I am suppose to do for this task?!?!

New Year Resolutions in 2008!

2008-01-01T08:56:00.000-08:00

Happy new year to all!!
We have had the first day in 2008 which is the best timing to make our new year resolutions that anything you want to have!!

First I will have to ask myself this question,
"Q1.What would I want to do this year?"

For answering this question, I would need to answer this question first,
"Q2.What is your short term goal that you set up right now?"

-->
A2.I wanna work in the US to become the real international software developer. Yeah, that's rigth. the following question comes like this. "why and what for do you set up such goal?"

-->
Yeah, because I wanna know how people in US work on a software development project, an wanna figure out the good ethics or bad compared with those in Japan or India.
And will find out the better way of developiong a system by mixing our and US people's good ethics!!

A1.so, things what I have to do to make it happen this year, I have to train myself techinical stuffs and experience more of system development with the US firm. and learn their business procedure.

For getting an opportunitity working in the US, I must have strong techinical experience and performance as a Java Developer, so my target will be like the followings...

---Goal List---
1.Work on ODesk jobs to gain more real work experience.
2.Get the SCJD certification
3.Familiar more with J2EE design which means in my case, study the Design Patturns(Head First Design Patturns.).
4.Catch up the Web2.0 technologies.--Ajax,JSF

and study more the English language...at least can manage the telephone interview with HR person in the US firm.

Wow, the goal that I set up looks very interested!!

ODesk vs Elance

2007-12-24T22:58:00.000-08:00

I may not have right to criticize this topic ODesk vs Elance, I've never worked on Elance fleelance work so far.

* look and feel
http://www.elance.com
http://www.odesk.com

Elance won. It much likes following on trend, then intellectual looking. but Odesk looks like made by a web designer fresher..

Job Interview on ODesk

2007-12-20T06:38:00.000-08:00

I had a job interview on ODesk. We talked by Yahoo! messenger when it was at around 23(GMT -5) interviewer time and mine was 13(GMT +9)..
( someone could guess where the interviewer lives ^^)

It was really fun to talk to and of course stressed me,, you know it always happens when anyone takes an interview.

But just now I got a notification from Odesk service that told me the job interview result.. It was failure...

I will make the other job opening.

Became an ODesk freelancer

2007-12-16T06:21:00.000-08:00

Have you heard "ODesk" before??

Last week I was just doing net-surfing for a while and accidentally I found this website.
Oh actually I was trying to find something new to get a job...
I don't remember the search criterias to find this service. But it looks really nice for me..

ODesk
http://www.odesk.com/w/

This website are really useful for the people finding a job and also proffecionals.
It is worthey to register your information to be a buyer or a provider!

I did anyway...

SCJD preparation

2007-11-25T09:53:00.000-08:00

as many of you know how much worthy the SCJD certification is, i agree its effectiveness.
i've decided to take the exam of SCJD of first step;CX-310-252A.

SCJD consists of 2 steps(do you know?) which are CX-310-252A(http://www.sun.com/training/catalog/courses/CX-310-252A.xml) and CX-310-027(http://www.sun.com/training/catalog/courses/CX-310-027.xml).

through be ready for this exam, we will know OO analysis&design,coding standard,javadoc,logger architecture,java network interface and more.

this exam focuses on J2SE and get better understanding of J2SE to know how smart we can use J2SE packages, and much more focusing on the OO design rather than just test if we know what the particular package is...

The time has come finally!

2007-07-15T14:59:00.000-07:00

We are really happy to say, complete the project internally.
officially we have some work,but according to our plan, it's over!

At the last moment, we knew who can be great contributer and who are not.
it's something like this.

For example, you gotta work something, and same size of work is given to others equally. you work hard and others also work really hard. but at the end of the deadline, a few guys said that they may not complete it by themselves. obviously they need some help, they are requesting to get any help.

in that situation if you are involved, you might have different thoughts.

1.the mind is that you wanna help them
2.and also you the thought that you wanna be free from work.

hopefully in our team we have some (1.) guys.
but some guys are (2.)...
how can we have more (1.) guys.
or how can we make people more (1.) guys.?!

cheers for ourself!

3 years needed to be popularin software product market?!

2007-07-14T14:02:00.000-07:00

it's the open source product now becomes popular.
it's the hibernate, AJax, Linux.
all products i got started to learn 3 years before which was in 2004.

now in India, they are saying that these products are must technologies which open system developer should know.

3 years took to be popular in the world.
even if nowadays technologies are rapidly developing..

End of Project

2007-07-13T09:10:00.000-07:00

The company im working for is middle size.there are almost 250 employees.
it's of course developing rapidly.
For one project, all the resources are being used.
Through running this project, we knew lots of organization problems.

HR process--->some guys refused to work for because of salary&evaluation issue.
Project management---->lack of experienced engineer, the way of handling with Japanese project by Indian manager.
Network system--->weak network,system infrastructure.
Engineer training process--->some engineer the company training given didn't show the performance.
work culture difference--->the way of working, or the understanding towards the schedule or promise or deadline.

im seeing what's happening now from inside of organization, im feeling this company is doing really well based on this much resources. this is my real impression.
but still it's hard to manage the middle size development offshore project.

but surely we are on the way to be the stable, big company.

we will make it based on this project experience ;)

Diet food is booming in India.

2007-07-11T13:39:00.000-07:00

the chain store in Chennai which is Nilgiri's supermarket is having diet food shelf.
by accident, i bought picked up the diet cookies and bought it.
(i thought that the price was Rs.15 for one pack of cookies, in fact it was Rs.155(aprx, 4bucks!))

it was the Joseph's Lite Cookies-->(http://www.josephslitecookies.com/home.cfm)
imported from the US, (i saw its WebSite, it says the product has been made by hand.. it's great!)

even if Indian currency is still cheaper than US dollar, it was sold by Indian people..
because this is really good for health (according to its Advertising Copy.)

Once you go to the book store here, you will see definitely the diet magazine and diet book corner...

For your information regarding with Indian life cost,
One lunch, it may cost around Rs.30 in local restaurant.
(you would eat enough volume of food!)

Joseph's cookie was actually really expensive.
4 times lunch cost equals to one Joseph's cookie!

SAP technology in India

2007-07-05T10:53:00.001-07:00

SAP is considered as the largest ERP package software product in the world.

in Japan SAP product are used for lots of the big company mostly which are in public.
SAP is expensive compare with other competitor's products. so that the demand for SAP are recently decreasing and instead of SAP, cheaper and smaller SAP package becomes popular.

my generation in the software field in Japan might think that SAP is gonna be dead technology just like mainframe field.
(in here "dead" means that it's just the less demand.)

lot's of software guys want to be in Java or .NET field in Japan.
(of course this trend also create another problem which is over competition..)

BUT in India, SAP is still poplar technology, there are still lots of training class for getting the certification and job ad for SAP engineer.
It is new for japanese..
at the same time, in India SAP is still poplar and in Japan SAP is gonna be lesser need.

one day i asked to my colleague working in SAP project about this matter.
he said that for becoming SAP engineer, we have to invest lots of money (yeah because of SAP software itself it's expensive.), so that once become them, they can definitely go and work in Good company or get the onsite opportunity.

I think his answer gets the point.

everybody wants to release the task.

2007-07-03T10:49:00.000-07:00

we are facing on the problem.
we, the onsite team where is in India,are working in development, testing phases.
everybody wanna send the completed task source codes to the Onsite where is Japan.
Because we want to send the source code ASAP, tester becomes no use.
they said while testing,
"yeah, it looks fine, no need to test in various test scenarios."

but obviously he was wrong.
even if we don't have time or dead line has come, we complete the whole testcases, and fix the all bugs before send to the Onsite.

let see if we delay the task but source code kept good quality.
or we keep the deadline but source code has lots of bugs.

i prefer the first case.
because it will take more time when the other guy try to fix the but than the developer in change does.

right??

we need to think realistically.

so i need to open my mouse to let them understand what is happening in the project.
we have to work smarter.don't only see and think current issues. try to think whole process and future views.

indian mind

2007-07-02T02:05:00.001-07:00

Good Afternoon from Chennai,India.

it's hot today on 2nd July.
sun shine is burning our skin to change our its color to dark brawn.
I haven't cought up any news lately so that i can only tell you major issues/news.

This year in 2007 is the biggest anniversary year for indian people and the country, India.

60 years passed after india was borned which means that this year is 60th independence year.
this celeblation reminds me of historical topics and various stories heard form my indian friends.

it's not related to the independence year,but it might be interested.
my friend told me that British exploited a lot from us.but gave us a great gift which is English.
we are proud of speaking/writing/reading English. that's why we are playing great role in world economy.
that's why we are getting more and more offeres to work for the US, the UK and so on.

Indian people appreciate british at leaset one thing.

how can you work on schedule??!!

2007-06-29T23:46:00.000-07:00

Morning has come to tell me that i delayed the schedule of my responsible task release.
Even if i have worked whole night..

let's think about the cause of delay.

1.short period schedule (or we can say wrong estimation )
2.incapability
3.unexpected incident occurred
4.ineffective work method
5.lack of resource
6.plan was not efficient.
7.resource allocation was wrong.
8.team management didn't work well.

mmm what is the real cause? or some causes are related each other?
let me take a succeeded example to identify the difference between my case and their cases.

how do people keep the schedule limit??
what are the differences??

oh, but how can i find the succeeded case??

useful information wanted ;)

no way to get away.

2007-06-27T10:04:00.000-07:00

I'm testing some programs, it might be released to the onsite tomorrow.
but my body condition is weaker because of continuous short sleep..

BUT, even if it's bad, i can't leave till complete the testing.
it's kinda hell.

who can survive under such work environment?
who wanna work?

people say to us like

"work harder! don't sleep a lot while you are young age"

you can get great experience and it helps you in the future.
they said like this.

we need to consider what you can get and what you loose.
have to compare&decide based on your priority and plan.

i choose already to work hard now.
so i can't say anything for their words.

if i say that don't wanna work long time which means that it is against my policy.

the professional person will never change their words.
they know how much it costs.

people will see you a lier.
people won't ask you anything.

so, this is really simple just keep your promise!

in my current case, just complete testing.
even if it will take till tomorrow morning.

i can say them like this tomorrow

"i compelted and prepare the bug report.i assume the bug fixing will take a half day, so i will be back afternoo."

yeah, it's great idea..

but im warring about the next my task.
if i will come late tomorrow, i will start next task at late time.
i might again work whole night.
it might repeat...

oh i need to cut this bad situation off one day.

nobody wants to work full night...

Task Allocation.

2007-06-26T17:49:00.000-07:00

Every morning we have to have a meeting with TM(Team Member)s.
and then make sure that every members is knowing what we are gonna do each day.

that's what just now my boss suggested me to do.
he sees me that i haven't managed the team.

i have lots of execuses.
for example.. oh sorry.. not sorry but,,

but if once open my mouse for saying it, i might become a looser.
i might not improve any more.

"execuse"

i hate this word. hate when i hear from somebody is saying.
hate to hear at the last moment when suppose the member completes thier allocated task.

so i won't do what i feel really mad when somebody does.
but insted of that, i will do to somebody what gets me happy.

this is good thing isn't it?
this is kinda my policy.

im guessing evrybody has same policy.
i mean i believe evrybody does!

so i accepted boss's suggestion and will follow his words.

be flexible, better have the room to accept my fault.
this is what really need to lead you to the next step.

internal condition.

2007-06-25T19:21:00.000-07:00

people see me im always active even if after we stayed up whole night.

i thought the reason why i look like that.

one big point is the mind we are having affects our looking.
we feel exhausted, mind feels tired, people see you exactly what you are feeling.
oh on the other word, what your mind is feeling.

so one suggestion to make you look active, take care of your mental condition.

how?!

you can search in the google!

oh! i got the first rank result is ---> http://en.wikipedia.org/wiki/Mental_illness

Spoken Language School... Japanese accent

2007-01-24T05:51:00.000-08:00

Yesterday i earlier left the office, was boring. kill my time tried to see the spoken language class.
teacher is a wife of my friend who i met for buying a secand hand car...
yesterday, i called him not to buy a car, to see his wife's english spoken class.

ironically,,,

he might be dissapointed because he might expect i wanted to buy his car....

so after left the office i went to their place where spoken english class is being held...

I understood at one grance how they are teaching and class atmosphere...
they chatted with enjoyment..
teacher looked energetic,confident,educatable,wise,warm,kind,helphul and positive...

it sounds like no reason i don't apply for her class...

I often think what's the english everybody can understand.
no more "sorry?", no more "pardon??"

How can we speak in english everybody can understand only one time?
(everybody means several nationalities, several language skill...)

it bothers me so many times.
because obviously i speak with my country's accent.

the teacher answered my question,

i remember clealy her word,

"learn(copy) my english" with smile on her face, confidence...

additionally, she said,
better learn british english, american english is srang...
or indian english is nutral...worth to learn even if it's indian accent english...

long long loooong way to be there where i reach to be satisfied with my english proficiency...

haha..

Drinking?!

2006-12-27T07:06:00.000-08:00

You know here in Tamil Nadu,
most of the restaurant are not allowd to sell an alcohol drink. if a few can sell, most of them can sell upto 10 or 11PM.

only very few restaurant can sell whenever they want.

so if people hold a party,
most of the cases, they do at their house...

my house owner is a paster who said to me, never bring alcohol inside of my house...

oh where can I drink after finish the work later night.

suppose in japan, on the way to home we drink until the last train,,, here in Chennai, never do it.

well,
be nice.
no more complainment.

jya!

The Hindu Jornalist

2006-12-27T07:04:00.000-08:00

yesterday, i made a friend in India.

his business card says his own website

http://www.gautamanbhaskaran.com/gb/index.html

when i will be free, i call him to go for dinner!

because i really like to watch a movie.it's really nice chance to satisfy myself.

beach running

2006-12-10T05:50:00.001-08:00

i would like to show a beach photo to you all.

this is where i always run on every weekends.

"put photo on here"

well, imagin local people are sitting just beside the waves. what they are doing is they do "No.2"..

in those sh*ts, i was running.

and it smells not good in there.
bad smell is come from center of chennai.
exaust gas, burning air,waist smell...

but just next moment, local child speaks to me with pure smile, "Hi!".
it always makes my feeling better, and makes my running speed faster.

so my life in India is mixed of good and bad moment.

but i feel, most of bad feeling is coming from bad environment.
most of good feeling is from people's attitude or smile or kindness.

so i can say,
in India,
people are really nice but environment is worse.

BTW,
today's dinner i used my hand to pick up food like indian style. it's nothing special. because i have done since I came to Chennai.

haha.

first experience is the rainy season(wet season)

2006-10-28T07:13:00.000-07:00

oh, it's terrible.

most of this week, a raining continues.

it looks like "tsuyu" in japanese word.

but i feel here is more heavy than japan.

the reason is savage system is not completed in here, so that lots of water remain on the road, it becomes the river , then becomes the flood. yesterday morning around office there was less water on the road, 4 hours later at lunch time, the river appeared everywhere!

I took off shoes then went to restaurant, it tooks double time than usual. wiped out pants then walked with naked foot.

yesterday was the first day the river appeared.

people looked like funny they were in the river on the road.

but i guess if it will continues for a couple of weeks, people would be tired of it.

actually for me, i feel stressful because i can't exercise on weekend...

as a business trip, i may go to Tokyo for a short time.

what i wanna do first is to cut my hair.

and go to "Izakaya", haha.

I am definitely "syomin" people, haha, not "high so" people.

Watami, Matsuya, Yakiniku...

finally i will shift to new place....

2006-10-07T04:02:00.000-07:00

hu-..

today, on Saturday I went to see a house whether i like to live or not. it looks.... not bad..actually indian standard house.
for me, lower than japanese standard, but, here in India,
shouldn't compare everything between them.

just accept the real.

then need effort for making it better if i want.
since i have started to look for a new place, it took over 2 months..

We have to pay a commision fee if we look for through a brooker.
normaliy it costs as same as one month rent fee.
and have to pay advanced fee. it's almost 8 months amount of rent fee...

money isn't matter, privasy and time is more important.
and free...

from next week, again i feel excitment like biggining when i came here..

viva new indian life!

oh indian inspires me!

2006-10-07T04:01:00.000-07:00

wow one of my wish is to feel good inspiration.
actually lately, i feel a lots.

because company japanese trainee learn japanese then they will be able to speak fluently in a half year.
i thought it's easy. and everyone can do that.

but i was wrong.
learning new language is quite tough.

"sorry japanese trainee, you are all great!"

why i feel like this is now i start learning local language.

"tamil"

quite tough, acutually....

I respect for japanese trainee now.

boring day...

2006-09-25T01:23:00.000-07:00

today, im doing nothing.
just killing time till leaving here.

today is the weekday people study or work all day.

I can see the different face of Bangalore from weekend one.

at 8 to 10, people commute office or school, then at 12 to 14 every restaurant is packed.

I will go for lunch after rush hour in restaurant.

now it's at 1:40 p.m.

but i think sometimes boring day is needed to reset my mind or refresh it.

i completly get bored...

oh..

anyway, Bangalore has terrible air pollution...
my lang hurts... from arrived here..

really nice friend in Bangalore

2006-09-24T08:41:00.000-07:00

I could meet the person who works in Bangalore as a software engineer.

every moment was really nice, he took us to popular place in here to make us happy.

I can find many differences between Bangalore and Chennai.

Firstly,richer people.
there are lots of car or bike in everywhere.
it means people can buy it are rich.

Secondly,worse transportation.
I tryed to go to the electolonics city where are lots of IT comany building such as Infosis, Wipro.
the way to there are terrible.
no one can stand to commute to the office.
now highway is under constraction. it may be completed in 2008.
I'm feeling chennai is really bad, but the one in Bangalore is worse...

Thirdly,multicultural city.
I saw lots of types of people.
religion, language, looking...
I heard many language in here, Tamil, Kannada, Hindi..
citizen in here must get used to multicultural atmosphere.the city building or street is becoming similar to others like tokyo, hang kong..

in this travel,
I visited nice place and had good time and got relaxed.
when you are tired of indian life, just go for there by air,train,bus.
it's worth to visit.

i could know new face of India.
i experienced very well.

thanks my friend!

first visiting Bangalore

2006-09-22T05:17:00.000-07:00

You know, from tomorrow to coming Tuesday I'll be in Bangalore.

it makes me excited, because it's the most famous, biggest software city in India.

For me working in India as a software engineer, knowing its features, atmosphere is meaningful.

it will give me idea for planning my future plan.

I wanna talk to somebady who works in there and then know how they are feeling about working in there.

and once more, wanna talk to one of the employee of biggest software compnay such as TCS, Infosys, Satyam, Wipro, TCS etc.

so that I can know where I am now, and what level of our company is it.

this travel is not like for private purpose, for researching or gathering the information of software company.

it sounds like for business purpose...

anyway, in there, I will drink lots of beer freely, and get relaxed.

because you know, some of state in India, selling alcohol is restricted.

The state i'm living is the one.

good luck with my journey.

haha.

=======================================================

Let's go for drink with me?

I wanna see someone who lives/works in Bangalore.

latest life report updation

2006-09-19T02:01:00.000-07:00

Recently, what i am doing is no use. nothing i done.
the direction i am walking is changed many times.
it's because my future plan is often changed.

At first, I wanted to work in India, because of special work experience,language ability, international business style, and enjoy the life of India.
for more than 3 months, i tryed to get all of them, to achive all my goals.
but life is the way we solve the problem.

so that of course, in Indian life, some problem(obstacle) exist.
resolve these problem have taken almost 4 months.
But im now gonna make comfort life which is what i expected in Japan.

after i will solve these problems i can do whatever i want and have a stressless life.
from everybody i can be free.i can use my time whatever i want.

first stage in India is to get used to living here, making comfort lifestyle.
so from now Im thinking what the second stage is.

what destination do i wanna go??
why do I wanna do this way? not that way?
through second stage where will I go to?
next second stage is third stage which is next 4 or 5 years later.
after 4 or 5 years later what person will I be??
how life will i have?

while i was laying down on the roof top in Varanasi, i was thinking of my future and current matters...
but thinking is good thing but no use to resolve the matter.
only thing can resolve matter is just doing by myself. have to take an action. nothing can do in my mind.
have to keep walking sometimes run toughly.

now I'm on the way to go where I wanna reach the stage.

these days what am I doing or thinking?

2006-08-20T07:09:00.000-07:00

you know, in India, people are really kind.
they rarely come to meet on time.
transportation is like a hell.
food is really taisty.
office worker only think their own carrer.
climate is awful especially afternoon.

compare to my country, living here is really tough.
but i think once you are getting used to live and work here,
here's life seems like much better than before.

yeah, now I feel so..

most of my time is used for working or building my carrer in here.
sometimes it gets me tired but chatting and eating with these nice guys releases my stress and gets my feeling better!

i have confidence to say, I like India, and its life.

but someday the day ends its life will come.
at that time i won't regret anything, just do it, just try to do.

"Do my best"

nowadays, I'm thinking like this way....

haha.

Yeah, try to view your situation.

2006-08-05T05:18:00.000-07:00

There is big gap between 2 people.
Good lemedy is to try to view opposition's situation.

Lets, view from opposition's side.
*what can you see?
*Is there something to solve conflict stuation?

Yeah, you could find the resolution.
or, Both of you might walk across their gap.

Usually, people think only theirselves,
because Most of people like theirselves the most in the world.

But, in mutial society, such kind of action lead to fail your way.
selfish action never bring the happy life.

In the developing coutries, this is common sence, poor people can't think other people, they don't have the room in their mind.
But, They know how to struggle to live in poor world, among poor people, they cooperate theiselves, for exapmle, work toghether, share the food,facilities, everything.(You can see when you visit the villege...)

On the other hand, in developed countries, they can live indivisiality, so that they have not experienced to share their stuffs or cooperate among them..
then they are tending to become selfish people..

oh, it's really hard to make sence what I want to tell you in this jarnal...

haha.

heavy rain forces me to ....

2006-07-27T06:45:00.000-07:00

Suddenly, Heavy rain came, it force me to browse internet..
Yes,now is in its situation.

Many people are standing front of shops, waiting stopping it.
It reminds me of my country's one.

In my country, you can see same scene at the entrance of station building.
While people is commuting to or from office or school, it starts rain, then some of them are forced to wait stopping it.

both of countries's people are doing same action, some people keep waiting, some start running in it, some call for help by mobile, others take taxi,,, like that..

But i feel small difference between indian and my country people...
the ratio of waiting people in India is higher than in my country.
just because they don't have other options except waiting.

Well, while writing a jurnal of this blog, raining may be stopped.
I can hear the loudly sound of thunder, but it seems raining is stopped.
Do you know here's sewage system??
Just 10 minutes or 20 minutes of raining makes big pound on many roads...
road range is shortened, then traffic jam must be worse...

yes, now my shoes are wetting because of it.

BTW, a few days past, I was given nice phrase by my friend.

he said,
"rabbit chasing by Lion never stop running, if stops, rabbit must be dead(eaten)."

Yes, here in India, Most of them are eager to get good status or high saraly.
they never stop learning(working) at least in my company.

furtunatly, the comparision to my country's people is almost same.
means, my friends in my country are learning as same as them.
I'm proud of this fact.

well, Im gonna be back to my house.

the wished future should be opened by me

2006-07-18T05:39:00.000-07:00

you know the meaning of this jurnal title.
people sometime couldn't make their way whatever they want..
they might be forced to do what they don't wanna do...

but in that situation,
how do they think the solution?

1.try to consider the best way??
2.otherwise, don't do anything, then follow their circumustance??

Of cource, people should choose first option.
If people are eagar to come true their wishes, must do it.

In the life, one of the important thing is that how the people live enjoyable.
when feeling enjoyable, people suppose to do along with their thoughts.

just follow your thoughs.
just think the following ways...
what do you wanna do?
what is the obstacle against your wish?

and one more thing,
what people wish strongly to do whatever they want shows you not-cool guys...
you might look selfish.
then you might be saying on your back...

so, please think like a fire but act like an ice.
it's one of the way you can come true your wishes without any antipathies.

haha!

Japanese film festival in India

2006-07-13T05:16:00.000-07:00

Now, Japanese embassy is holding the japanese film festival, in Chennai.

This event must contribute to introduce the japanese culture to them.
The movies selected are very nice.

the yoga life

2006-07-09T02:41:00.000-07:00

im glad to inform this info,

from today, my yoga life is going to start.
so happy and good stimlus for you.

haha,

my body may be tremendous flexible!!
but its not cool i think, but good for fun!!

anyway, I cant wait to take a class.

if you come to india, I can arrange short yoga course for you all!!

anyway, for what people do the yoga??
what is the purpose,aim??

for health, fun, mind, spirit, a lots of effects yoga can provide.

I visited a few yoga class for reserch the timing, price, method, atmosphere...
I felt nowhere is same place, and difficult to find best place.
so , i decided the class held by friend of my friend after all.

I tell you the price range.
the most expensive place among the places i visited,
1) first month Rs2000 from next month Rs1000, once a week, 1 class is for 1 hour.

next is cheepest one.
2) one month Rs500, third a week, 1 class is for 1 hour.

do you think big difference??

through seeing a few yoga classes, I supposed to imagin what yoga is.

well, lets do it oneself!!

double price range?!

2006-06-30T23:39:00.000-07:00

at all the developing countries, there is same situation as india.
I tell you the price range for lunch.

[lunch]
1.traditional lunch.
rice with 2 types of sambar, one fried stuff, 1 tsp of pickle.
--- Rs.14

2.modern cafe lunch.
a cup of black coffee
--- Rs35
chicken rolled chapati
--- Rs60
---total Rs95

modern cafe food couldn't get me full, indeed, waste my money.
all my co-worker are surprised with cafe's price.

but, we can see the double range price not only food but household appliance, car, cloth, everything!

1 month passed exactly today.

2006-06-30T23:36:00.000-07:00

wow, time passed tremendously fast!!
everything is going well.
people say that "I can get used to live soon".
yes, it's mostly correct.
but someparts are not correct.

I don't wanna suit some indian habits, that's why i have something i didn't get used to yet.

but mostly they are relly nice and all japanese can learn from them many things.

"they think,act,live simply"

-who care about other's thought?
-no,nobody.

it's one of the best way to be simple life.
try to forget your around circumstance.

they look older than us.

2006-06-25T07:33:00.000-07:00

oh my godness.
I didn't expect he was 16. he looks at least 20.
Most of Indian guys look older than japanese.
but I can say from another way.we look younger than the other countries's people.

Im also said that I look univ. student or 20 to 22 years old.
but im not.

let's try to guess their age in first impression.
you may be wrong.
but you see and talk to many indian, you can guess corectly better than before.
this is same as others.
like a studying english. at first we can't catch enligsh, but keep listening,

I wish I would be able to upload image data.

2006-06-23T05:53:00.000-07:00

Hi,all!

Here in India, nobady can stand to live if dislike a bugs,animals,dirty sight&smell.

I got used to live with them.if you do, your indian life is gonna be nicer!
I see cow, black bird(forget a english word), dog, goat, horse.
and mosquito,fry.... every day.

they make a peaceful sight.
Pls,imagin,,,
a bird is stopping on a cow's back
and a dog is lying and resting beside a cow under cow's shadow in early morning.
they are living cooperatively.
how wonderful they are.
Also human live being cloth to each other.

They try to share every resouse, food, house, privacy, money, happiness, sadness, marrigement, work, future in their family!!!

That touch my heart strongly!!
They teach me and show me many things I've never experienced.

I wanna show you some photos to experience the part of my experience.
But still use a internet cafe banded to upload image data.

please wait the day is coming I use own internet service at my house.

Something is gonna be better!!

2006-06-16T23:53:00.000-07:00

My feeling is better than before I was depressed little bit in here.
Because my life is clother to my expectation I had in japan.

and then, I can be nice guy to teach them japanese.
but, real adult guy is not like such a person.
I mean the person dont reflect from surounding mood.
He can always control himself.

I wanna be like him.

someday I'll be like him and i can infuluence well to others.

BTW,
Here in india,I rarely see a person who hurry to do something.it's not as same as in japan.

and my collegues express their thoughts even if they talk to the CEO or have a job interview.

Im learning it from them.

haha.

sometimes,I can feel the effectiveness.

for example,
I ordered the photo service print 16 passport size photos.But the photos looked really bad, like a , there are green color stuff over my face.
and can't see my face clearly.When I received them at the shop, I claimed them to reprint my photos, storongly.

Before, i came to India, I think I didn't say strongly and claimed like that.but now I do as Indian do.
and after that i could get new and clear photos and their apologies(in india sometimes they dont accept their fault).

haha.

but I understand the "TPO". when Im in japan I follow a japanese style.

2 weeks passed after working here today

2006-06-14T06:33:00.000-07:00

2 weeks passed after working here today.
everything is funny.

do you wanna know how i feel this life??

I feel I choosed the one of my best option.But it's still hard to do tha way i expected in japan.
only thing I can't control the situation is that

"i speak japanese more than english everyday."

because every guys wanna know japanese and they ask me in japanese, then ,of course i response in japanese.

Their eyes are really blight, i mean , they are quite willing to be better japanese speaker.

I wanna help them heartly though.
but I also take care of myself, i wanna improve my english.

so, it's difficult problem.
"I wanna help them, but simultaneously, I wanna improve my english."

oh, what a small men i am....

2006-06-02T23:37:00.000-07:00

It pasts 1 and half days to come India, Chennai.
Now I'm creating this message from internet cafe nearby the place I stay.

Thanks for coming to take care of me to the Kansai airport.
I could come here completely safty.

Anyway, At the office, I only speak Japanese...Because the guys who are my co-workers want to learn japanese and I'm forced to talk to them in japanese....

It makes me sad, but I'm not negative, I learn enligh by myself, dont think that I rely on the others who are my co-workers. I will make a friend with the person who can't speak japanese. Of course I think I'll keep really good relationship with my co-workers.
I think I can be stronger than before.I learned to be strong from many experience of living in many countries.

Well, I'll be back to the guest house(my place).

I love tennis!!

2006-05-26T12:26:00.000-07:00

I played tennis almost 4 hours today.
My body is all sore...
like a after doing push up.

I had not played tennis with them since I moved to Tokyo, for 2 years.
I didn't know whether I could join them, but they accepted me with great smile.

I was appreciated with their kindness.
They reminded me of the memory of playing tennis at there.
It can be comfortable time to rethink about it.

In the future, When I will come back to parents house, I also wanna come back to the tennis court and play it with really nice people!!!

I can't wait to play it again, probably, I'll do it tomorrow or the day after tomorrow!!
Oh, there is kind of heaven at there.

dinner with my father

2006-05-25T09:56:00.000-07:00

Last dinner with my father was long time ago.I can't remember exactly when the last day was.
My father was tired because of his work but he talked to more than usual day.
He also thought today was something special for us. We talked to about him, me, brother, sister, relatives, grand-ma, and a lot!!

and At the front of counter, I paid our dinner for him by credit card.
I tryed to make him happy and wanna give something to him, because I was appreciated for his help for me.

and I think today, I can be real man, not child of him.

Thanks a lot, Daddy!!

playing tennis with people live in my hometown

2006-05-24T05:13:00.000-07:00

I'm gonna play tennis for a week.
For me , what I play tennis reminds me my memory of junior high school or high school.
I used to play really hard for that time, I thought only tennis for 6 years.

For people, It's really important to do something hard and try to achieve their goals. That imfluense theirselvs of goodness.

What is the thing like playing tennise of mine for you??
Succer? Baseboal? swimming? misic? reading? video game?

It get yourself really fine, if you have it!!

Back to my parents house

2006-05-23T11:26:00.000-07:00

Finally, I came back to my parents house in Osaka, Japan.
I had not been here since this new year vacation.During that time i didn't come back, It happened many things to my family.

1. my first nephew was borned.
2.my sister got married.
3.I quited a job.

I think I talk to my brother, parents, grand mother, brother's wife a lot for a week I'm staying in here.

Tonight, I saw a picture of nephew, he looks like stuborn and calm and strong boy.
He is , of course , similar with my brother but, my mother said, he is similar with his mother.
I don't know the truth, but I'm just releaved that he looks really fine!

My brother said to me that he will take a baby to here to see me, because I won't be back here for a couple of years so that he wanna me to remember a baby's face.
It must be different face if after it pasts for a couple of years like 2 or 3 years.

A baby grows really fast!
