Since upgrading to Ubuntu 10.10, my laptop’s touchpad has been giving me problems. The left button does not work anymore. Actually, it works occasionally, but it always stops working especially when I need it the most, so it might as well be considered not working at all. Only the left button is not working though, [...]
I have been quite annoyed recently by the sluggishness of Ubuntu Gnome desktop, even on a laptop with AMD duo-core CPU and 2GB RAM, and after trying to cut down to the bare minimum of applications for my daily works. That’s certainly not a top of the line machine, but surely not an antique either. [...]
Erlang is great platform, however, if you want to develop Erlang programs, the best development environment is probably Emacs at this point. In this post, I’m describing the tools you need, and how to set up to develop Erlang codes. The OS is assumed to be Debian-based Linux (mine is Ubuntu 10.04). First, make sure [...]
The sync tool that was supposed to sync data between your laptop and your mobile device crashed, and you are in a hurry to get the information on your computer to your device. What would you do? I don’t know about you, but I took the shortcut, although a very stupid one. For those who [...]

In that case, if the guest OS is Ubuntu (or other Debian-based distribution), the network interface is also [...]
Most modern computers have multiple cores, and even new multi-core processors are available for portable devices now. Yet, software are not taking advantage of them. Processors are sitting idle, doing nothing, most of the time. A lot of frameworks, libraries, language extensions, and even new programming languages, have been proposed to take advantage of the [...]
Ubuntu 10.04′s repository only has OpenCV 2.0, but if you want to use the 2.1 version, which was released in April, you would have to build it from source. Here’s a simple how-to. First, you need to install the following required packages to build OpenCV: libgtk2.0-dev libpng12-dev libjpeg62-dev libtiff4-dev zlib1g-dev libjasper-dev libavcodec-dev libdc1394-22-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev [...]
In my previous post, I was talking about how unreliable it is to sync between Windows Mobile and Linux (Ubuntu to be precise). SynCE, OpenSync, etc, still had a lot of bugs. And believe it or not, those bugs are known for a long long time, and they never got addressed. As in my previous [...]
One of the annoying things of using Linux has been to get your personal data synced between your Linux desktop and your mobile device(s).
