me and my stuff

Today I'm looking for mp3 player for my ubuntu. Feisty come with rhythmbox but after few months using I think it's time to try something better. Rhythmbox does not let me edit idv3 tags and [for me]it's hard to manage library so it's not acceptable. All I wants are a) idv3 tags must editable. This is important for me because some of my mp3 collection don't have info in tags or some have a wrong info. b) full support thai language. c) gtk+ application will be good. I found this blog [http://onlyubuntu.blogspot.com/2007/03/media-players-available-for-ubuntu.html] list some media players in ubuntu. I choose some to try[all are easy to install in Feisty just 'sudo aptitude install <packagename>'] Beep Media Player is like xmms. If I'm not wrong I think the project is stop now. Amarok come with great interface, full of features but it's KDE app so it's need some other kde package to install and run. Exaile, like KDE's Amarok but it's G...

The problem about playlist on media player are unreadable when it use thai character. This is caused by different encoding used in id3 tags and in media player. Id3 tags use cp874[don't know why] but in current linux distribution, player use unicode. This will not be a problem if tags are english characters that cp874 and unicode has the same value e.g. 'A' is '0x41' for cp874 and '0x0041' for unicode, but not for thai character. To correct thai character in playlist. There is a script to convert 1-byte charsets to unicode[ download ] by Kopats Andrei. Now what to do: 1. download the script. You'll get 'tag2utf.py'. 2. install requirement software sudo apt-get install python-eyed3 3. in the script, looking for charsets = {'cp1251':'c','koi8-r':'k' } and replace with your language encoding[ for thai change it to charsets = {'tis-620':'t' } ] Now we ready to convert mp3 tags. run script by 'tag2u...

Yesterday, In the morning my boss tell me to looking at the router. It blinks like it'll going to blow up. Something in our network use almost 60% of my bandwidth. I look around and see that network light on the acient small box on the floor blinks too. It's a secondhand computer from japan and I almost forget it. On that box,I install dapper server,postfix,courier,mysql and use it as a mail server with no firewall. poor me. :( This is first time I got hacked(as I know hah ha). I've no idea what to do first. I go to check /var/log/auth.log and found many ssh attack. 'who' give me two users online, me and test1[the hacker]. 'top' show that user test1 run tons of ssh-scan process. I can't remember that did I create that test1 user myself or the hacker do a dictionary attack, found my password then create test1 user. What I do at that time is restart computer, delete test1 user then create a firewall . Then I go to ubuntuforums and found this thread . It lo...

To add/remove service in ubuntu. Manually you can put init script in /etc/init.d then create symbolic link from /etc/rc?.d/S[NN]name or K[NN]name to /etc/init.d/scriptname.[S for start and K for stop] In ubuntu has a tool to manage init scripts call update-rc.d. For example if you want to start serviceA in runlevel 2 3 4 5 with sequence number 18 and stop in runlevel 0 1 6 with sequence number 99 use the command.[the scriptA must already create in /etc/init.d] pnix@pnix-a7n:~$ sudo update-rc.d serviceA start 18 2 3 4 5 . stop 99 0 1 6 In redhat base linux, i use chkconfig do the same thing. For more detail try 'man chkconfig'.

After running the system for a long time. Today I found few things I should do to clean the box. First clean the old package files in cache, When you do "sudo aptitude update|upgraed|install", the packages will be downloaded to your local disk[ locate at /var/cache/apt/archives/ ] then installed. If you try ls that directory you will see how many packages you've download. To prevent these cache from growing we should remove some outdated package by pnix@pnix-a7n:~$ sudo apt-get autoclean Password: Reading package lists... Done Building dependency tree Reading state information... Done Del compizconfig-settings-manager 0.1.0+git20070717~3v1ubuntu0 [461kB] Del libcompizconfig-backend-gconf 0.1+git20070709~3v1ubuntu0 [29.5kB] . . Del libdecoration0 1:0.5.1+git20070706~3v1ubuntu1 [2401B] pnix@pnix-a7n:~$ next install localepurge.

From last post about tag in jsp. This post is about directive tag in more details. Directive tag can devide into three types e.g. page, include and taglib <%@ directive attribute="value" %> page directive : page directive will provide the information about the page for jsp engine to compile that page. Below are some importance attributes of page directive : language tells the engine about language that the page is using. usage: <%@ page language="java" %> extends tell jsp engine that this page will extend from specify class. usage: <%@ page extends="test.myclass" %> import used to import any class to use in our jsp page. We can use comma(,) to import more than one packages. usage: <%@ page import="java.sql.*,mypackage.myclass" %> session="true|false" , default is true so jsp pages are session enable. usage: <%@ page session="true" %> buffer , control buffer usage for that jsp page. usage: <...

Today I upgrade utorrent[sure on feisty] from 1.6 to 1.7 then restart utorrent. This upgrading cause unused parts of uTorrent's window are black. That's annoying me. After some searching, look like it wine bug , I run with wine 0.9.40, the newest one. The black window area will happen when use in mode

JSP is the html page that add java code[called JSP tags] into it. JSP tags can be devided into 6 different types. These are: Comment tag use to add comment. <% --comment here-- %> or <! --comment here-- > Declarations tag use to define the variables,methods or classes to use in the JSP page. <%! Declaration1; Declaration2; %> Scriplets tag use to insert java statements. <% Statement 1; Statement 2; Statement n; %> Expressions tag use to print out any data on the page. These data are automatically converted to string. <%=[Value] or [Expression]%> Directives tag is used for many purposes depend on directive and attribute in tag. there are three directives page, include and taglib. <%@ directive attribute="value" %> Action tag is use to transfer control to other server objects[ex. pages] or perform operations on other objects. <jsp:action attributes /> action tag has three types e.g. include,forward and usebean.

Two weeks ago, I read on ubuntuforums and found this thread about how to get compiz fusion work on ubuntu fiesty . It show you clearly step by step how to. Today I'm just decide to try and it's real amazing. 3D Cube and many effect feel smoother than the old compiz from repos. It's work on my asus n6200td 128M card, my memory is 512M, athlon xp 1700+ and A7N8X-E mobo. Compiz fusion still development version but for me it's very very very stable. So I urge you to try it now. Compiz Fusion is merging of compiz and beryl project. It's not on feisty repos yet but may be on Gutsy Gibbon.

Usually when I want to make a request over network in java I familiar to use Socket class like this. Socket theSock = new Socket(server,port); PrintStream ps = new PrintStream(theSock.getOutputStream()); then uses ps.println() to send a request and uses theSock.getInputStream() to reciece response to see everything that sent over output stream. But this maybe not suitable for all situation. Talking with web server will be done through HTTP message[request,response] that consists of header and body . So to make a post,get http request [with Socket class] //Post ps.println("POST uri HTTP/1.1"); ps.println("Content-Length: "+body.length()); ps.println("Content-Type: "+contenttype); ps.println(); ps.println( body ); //or Get ps.println("GET uri HTTP/1.1"); ps.println("Connection: Close"); ps.println(); and web server will responds with HTTP response like. Here's the example. HTTP/1.1 200 OK Date: Wed, 04 Jul 2007 10:14:54 GMT . Conte...

Last week I need to post data in xml format to one server. For security reason one node[xml] require 3DES encryption and encode to Base64 before send. It's a good idea to encrypt sensitive data before store in database or transfer over internet but I'm not even know what 3DES is. After some search, I found that it's not too hard. This post is about how i encrypt data in java. 3DES algorithm use symetric key[secret key] to encrypt or decrypt data. So.. First define a key [ length must be 24 bytes ]. I do this by getBytes() from random string. byte [] seed_key = (new String("er48nsjhwlG593mjhgdb20ih")).getBytes() create Cipher object SecretKeySpec keySpec = new SecretKeySpec(seed_key,"TripleDES"); Cipher nCipher=Cipher.getInstance("TripleDES"); nCipher.init( Cipher.ENCRYPT_MODE, keySpec ); Cipher class provides the functionality of a cryptographic cipher for encryption and decryption. To create cipher object, pass transformation to getInstance m...
