Install Java SDK and JRE in Ubuntu ?

Want to install Java 2 SDK (j2sdk) in your Debian or Ubuntu? Well, I’ve created a home-made package for Java 2 SDK 1.4.2.

First download the deb from either of this mirror:

  1. Rapidshare.de
  2. Mirror #1

and after that, just do :
$ sudo dpkg -i sun-j2sdk1.4_1.4.2_09_i386.deb

and Sun Java 2 SDK 1.4.2 should be installed in your system by now. You can refer to https://wiki.ubuntu.com/Java if you want to build other Sun Java deb package (like Java 1.5.0)

That’s all for today folks, happy programming in Java!

I’ve received Ubuntu CDs!


My Ubuntu CD


Mypapit Ubuntu CDs

Hello there, yesterday I received 10 set of Ubuntu 5.04 “Hoary Hedgehog” CDs from my friend. He gave me the CDs to be distributed for other people who wants to use GNU/Linux.

Ubuntu is a nice distro for people who want to start using GNU/Linux. It Ubuntu is newbie-friendly and has a nice selection of applications to start over with. Ubuntu uses apt-get package management system which enables user to receive package updates and upgrades.

The Ubuntu pressed CD cover is nice each sets contains 2 CDs, the typical installation CD and the LiveCD. The installation CD can be use to install GNU/Linux inside your pc, the installation process is fairly easy and simple to follow. The LiveCD is for people who wants to test out Ubuntu without installing them, you can boot the GNOME desktop, and can start using GNU/Linux immediately.

I’m planning to give away the CDs to my friends and to my sister, as well as to anybody who really wants to use and learn GNU/Linux. They might be a couple of leftovers CD, so if you want the CD, I can send it to you also, just email me for details.

I’m Officially a Debian GNU/Linux user now!


Debian Logo

I’m announcing now that Debian has become my official GNU/Linux distro. Previously I’ve use Mandrake (my first distro) as my official GNU/Linux distro, then Slackware, and finally SuSE. Fedora Core 4 actually was on my candidate list as my next official distro because it’s spiffy package management system, but in the end i chose Debian over Fedora.

Debian is more flexible than Fedora because I can download only one CD out of 12 CDs to perform complete installations. Well, people might argue that Fedora can do the same, but the way Fedora did it wasn’t obvious. And you apparently have to end up downloading the entire 4 CDs, which turn out not enough to fully enjoy the distro (Fedora people assumes that most people code in Java, and put a lot of java things inside the CD)

Well, Debian is a nice distro for me, it isnt too bloated, easy to configure, and it has a good package management system. I like Debian.

p/s: I’ve installed countless of other distros before this, but the “official” status is only given for distro that i use for my production purposes and usually meant to last more than 9 months on my pc.

When Microsoft write about GNU/Linux-related tutorial

I came across this official article in Microsoft Help and Support Website.

What worth mentioning about this article is, this is the first Microsoft article that explains a little bit about GNU/Linux filesystem accurately and in non-biased way against their own filesystem.

This article also feature short tutorial on how to use the GNU/Linux “fdisk” program, including “fdisk” keys to create, write, and delete partition. The Linux disk/partition terminology such as /dev/sda, /dev/hda1, etc, are also explained in this tutorial. Yeah, something that I never expected from this company, but they did it after all?

Wanna know the catch?

Open Source Windows and Linux Games

Have you ever felt the urge to kill off your time while you are working? A sense to release your tension from boring repetitive work at the office (or at home)?

Of all those burden and urge, you might have downloaded games from the internet and scored a few good round out of it, only to find out finally that you cant write your name on the high score list because you need to register first.

How many times you came across games you downloaded from the internet which impose delayed “unregistered” splash screen, denied you from high score list or even stopped working after a few days of installing?

The game locked you out from your own windows system, and some even installs malicious adware or malware that contaminate your windows!

Well not anymore if you choose the way of the Free (as in freedom and beer) path.

Their selection of games is quite good and moreover is Free! The games are not only nice and small, but they also come with complete source code and covered under the GNU General Public License.

Another place to seek FOSS games is at the LGames project hosted at Sourceforge.net. Most of the game listed here are rather clone of popular arcade games, excepts they comes with source codes and installer.

Most of the games featured on the website mentioned here are created by the portable libSDL (Simple Direct Media Library) which ease of the process of developing the games across numerous platform.

Please show your appreciation when you can and donate a few bucks to them. I’m sure they will return your gesture :)

Linux kernel patch, Nano devfs hacks

Linux Logo

Greg KH have released “nano” devfs patch for the current linux kernel to mitigate the concerns of embedded system developers.

However according to Greg the inventor of udev (userspace /dev filesystem), he is not going to submit ndevfs patch to the main kernel tree. He explains it in his words :

“I’m not going to be submitting this. But what it is, is a nice proof-of-concept for people who ‘just can’t live without a in-kernel devfs’ to show that it can be done in less than 300 lines of code, and only 6 hooks (2 functions in 3 different places) in the main kernel tree. That is managable outside of the main kernel for years, with almost little to no effort.”
