A witty advice

Posted by Willy Permana in Komputer on May 22, 2010

My netbook webcam doesn’t work properly on BlankOn Nanggar. It can capture images, but it will be displayed upside down. After several hours googling, I finally get some sure workaround to solve this problem.

*Try holding your computer upside-down*. Dead simple, no? :)


Even though I already used the libv4l library, the webcam still displaying images upside-down. Maybe the webcam still haven’t been included on libv4l table on Nanggar release.

Well, it’s not like I badly need to use the webcam. But I do hope it’ll be fixed on the next BlankOn release. Maybe it’s already fixed on Ubuntu 10.04.

E17 a.k.a Enlightenment, a lightweight window manager

Posted by Willy Permana in Komputer on March 30, 2010

Recently I’m trying Enlightenment, a light window manager. I’ve known this app for a long time, but only recently try to install it (I blame Dedi for tempting me :P ). I usually use GNOME. It’s virtually the only desktop environment I ever use. KDE isn’t up to my taste, and I rarely use XFCE anymore since my Xubuntu box has been monitor-less for a while.

The installation steps are the same as posted on Dedi’s blog, with some minor changes. I use old repo key because new repo key will give a GPG error. And since I’m using BlankOn Nanggar, I use packages for Jaunty.

  1. Edit my sources list

    2. $ sudo nano /etc/apt/sources.list

  2. Add following line

    3. deb http://packages.enlightenment.org/ubuntu jaunty main extras

  3. Add repo key

    4. wget http://packages.enlightenment.org/repo.key.old -O - | sudo apt-key add -

  4. Update packages and install Enlightenment

    5. $ sudo apt-get update
    $ sudo apt-get install e17

  5. Log out and choose Enlightenment session

Enlightenment with Clearlook theme


You can get additional theme, app and stuff for Enlightenment from http://e17-stuff.org/ and http://exchange.enlightenment.org/ (Thanks Dedi, for the link :) )

So, do you want enlightenment? (Hahaha, bad pun, I know :) )

Note: Ubuntu repository also got Enlightenment packages, but it’s still an e16 version.

Getting Ubuntu .deb packages using apt-web

Posted by Willy Permana in Komputer on March 20, 2010

At home, I’m using Ubuntu 8.04 for my main OS. Unfortunately, it’s not connected to internet. Whenever I need to install anything, I had to download it manually from Ubuntu repository. (Well, I also using BlankOn 5.0 at my workplace, but since BlankOn 5.0 is based on Ubuntu 9.04, I can’t just copy its packages in apt cache and copy them to my Hardy machine.)

Manual download has it own cons. Ubuntu repo website do lists the dependencies for a .deb package, but how do I know what’s the dependencies for the dependencies, or whether some of the dependencies are already installed or not?

This is where apt-web, a web-based .deb package finder application developed by mas Fajran “Iang” Iman Rusadi, came in. It helps me to know which packages I have to download and gives package URL on chosen repository mirrors for any specific release. For instance, if I want to install inkscape on Hardy, apt-web let me know that I only need to download two packages (inkscape & libmagick++10), either from Kambing, Buaya, UGM or other mirrors.

Neat, eh? :)

To try apt-web, you can visit http://apt.web.dahsy.at

Happy unbirthday!

Posted by Willy Permana in Komputer, Usil on March 11, 2010

Uhh, I guess today is not my unbirthday. But yesterday is my unbirthday. My 9106th unbirthday, to be exact.

What’s an unbirthday? Why, it’s any day that’s not one birthday, of course. It’s a term first coined in Lewis Carrol‘s novel Through the Looking Glass.

Now, how do we check how many unbirthday has passed? If you’re using Debian/Ubuntu or their derivatives, you can install python2.6-examples package, which include a script to count your unbirthday days. For other distro or OS, please refer to included manual :P

$ sudo apt-get install python2.6-examples
$ python /usr/share/doc/python2.6/examples/Demo/scripts/unbirthday.py

If you’re interested on the novel, you can download it for free from Project Gutenberg website.

BlankOn incompatibility?

Posted by Willy Permana in Blogging, Komputer on January 21, 2010

This morning I was accessing this blog with Opera 10 on BlankOn Nanggar. Everything went fine till about noon when suddenly my blog displayed only as text. No image, no CSS whatsoever (save for the Facebook badge, which rendered fine). And to make matters worse, I couldn’t even access the admin page.

It’s quite strange, as the blog is accessible using Firefox on Windows XP (else there’s no way I could write this post). Wondered what went wrong…
