3D Visualizing Quantum Chemistry Molecule in Ubuntu Edgy

First of all, I'm not a chemistry scientist at all. It is not my field. This era, we are on the globalization and multi-disciplinary interaction. I am just a computer engineer and any fields might involve to computer. Actually, computer itself is absolutely useless as long as you don't have applications to run. Recent drugs are officially recovered using virtual screening technology based on computational science where as computer system is used as a key component to simulate the effect of each drug candidate instead of going to try it in real laboratory. This technique is a part of quantum chemistry. Not only simulation is used here but also visualization is another critical part. I can't remember how to explain the structure of a molecule but I'm sure it must be in 3D plane. Human may imagine how it is but it is impossible to communicate to others by just description. The only way to solve this problem is 3D visualization in computer. That's why I'm here. Moreover, my box is Ubuntu Edgy. I have to find my way to visualize input/output in 3D.

Flexible BitTorrent Client for Embedded Devices

Today, I and my colleages were thinking about embedding BTQueue into a kind of Linux-based router. Well, it is not easy to do so because of the nature of Python interpreter and its slogan.

Battery included!

I found Python for OpenWRT. It looks very promising and amazing by its size about 20 MB. In short, it is only usable on any routers with big flash memory or with USB for external storage. Unfortunately, these routers are not available in Thailand. So I suppose to have an embedable version of BTQueue. How to do that? The easiest solution is to slim down Python. I found Tiny Python. Anyway, it is just for MS Windows platform. So I looked for another solution not limited to just Python. Lua might be a good candidate here as a glue to ctorrent or libtorrent. The full set of Lua is about 100 KB.

How to convert MP3 to AAC using FFmpeg

MP3 is one of the most popular audio format for a decade and now it has a new competiter called AAC. Many recent audio players are supporting both formats. Who's know one or both of them may lose in this competition. Anyway, some players only support AAC right now. That's why I have to post this howto.

Trying Emacs 23 on Ubuntu Edgy Eft

There are 2 editors in this world I would like to try. The first one is Vi which is my favorite editor for years. The second one is Emacs which many people suggest me to try for getting another experiences. I have tried Emacs many times with no luck. I was unable to use it as I wish. Even getting out was not easy for me. Now the time has come for my next chance. This time, I have advisors and supervisors to help me get through this trouble startup to change my life. Don't worry, Vi is still my first choice on remote connection via ssh. Thanks to all expertists at Codenone.

BenQ Joybook S52 built-in sound card partially work with ALSA

Wow! It has been about 7 months since I migrated to Ubuntu Dapper in my laptop, BenQ Joybook S52, with on sound. During that time, I live with a USB sound card. As I mentioned in the past, this issue has been posted about 19 months ago. Fortunately, this issue has big progress last week or two. Congratulation for all you having BenQ Joybook S52 and S53 series!
