Vietnamese typing on Linux

For the list of other platforms, please see my old post: Vietnamese typing.

This entry is mostly for Ubuntu Linux, yet it can be applied on other Debian-based distributions, and probably some RedHat-based distro too.

My upgrade from Hardy Heron (8.04) to Lucid Lynx (10.04) went smoothly on desktop PC, but on laptop there were some small issues.

Here are 2 major issues then and how I solved them:

1/ Grub error: boot into text mode only, could not get GUI by startx or xstart command
==> SOLUTION STEPS: fix the old grub (not grub2) menu.lst (or edit boot menu directly)
* Change root partition from by-uuid ("root=UUID=asdf...") to by-path ("root=/dev/sda7")
* Change kernel version from old Hardy (2.6.14-19-generic) to new Lucid (2.6.32-22-generic)

2/ Sound error: could not hear sound, conflict sound system of YouTube/StarDict/VLC/MPlayer
==> SOLUTION STEPS: a little painful
* Run gnome-volume-control to uncheck "Mute" options, try changing sound theme (Ubuntu/NoSound/...)
* Install gnome-alsamixer or pavu, adjust the options and volume
* Resolve the libflashplayer.so location for Flash and libnpjp2.so location for Java RE.
* For StarDict, use aplay as command for playing sound files (usually in /usr/share/WyabdcRealPeopleTTS/ )

Some minor issues may be possible:
- (Gnome) combination (Alt+F2) does not work ==> SOLUTION: enable the "Gnome compatibility" plugin in CompizConfig S Manager (ccsm)
- Postgresql 8.3 startup failed due to memory segmentation ==> SOLUTION: open file postgresql.conf in /etc/postgresql/8.3/main/ and reduce value of the variable shared_buffers (for example 32M -> 16M)
- Some custom launchers' icons are changed ==> SOLUTION: find alternatives in /usr/share/pixmaps/

Hope this helps,

Y!M pager server

is down for Y!M 6.5 and prior versions:

( http://mediocre-ninja.blogspot.com/2009/06/pidgin-ym-connection.html )

Compatible clients such as Pidgin and Kopete suffers, too. But if you upgrade to the recent versions, it should be fine.

For pidgin (on Ubuntu), you need to upgrade pidgin-data to 2.5.7+ to work with new Y!M protocol.

Xmarks for Chrome

Lâu nay thằng FF 3 trên Ubuntu (lappy) cứ bị lỗi ì ạch, chuyển sang 3.5 vẫn chậm, 2.0 thì chạy được nhưng nhiều add-on ko compatible, thế là phải xài Konqueror và Chromium .

Hai cái này xài được, chỉ vướng 2 chỗ là bookmark (Xmarks) và zoom. May quá bây giờ Google đã release Chrome bản chính thức cho Linux , không những chạy Flash phe phé, mà còn zoom khá hơn, và Xmarks cũng đã hỗ trợ :

bye bye FireFox@lappy !

Maven Archetype quick notes

maven-archetype-plugin allows the user to create a Maven 2 project from an existing template caled an archetype.

If you just use an IDE to generate Maven project, you can be familiar with default project structure of Maven:

Let's consider an example using it to create a "todo-list" project which contains 2 sub-projects: todo-core and todo-web

cd workspace

mkdir -p todo-list

cd todo-list

Old-fashioned way:

mvn archetype:create -DartifactId=todo-core -DgroupId=org.vnoss

mvn archetype:create -DartifactId=todo-web -DgroupId=org.vnoss -DarchetypeArtifactId=maven-archetype-webapp

New way:

mvn archetype:generate

mvn archetype:generate -DarchetypeArtifactId=maven-archetype-webapp

Now we can edit the pom.xml to get desired result.
