Robots

Since I've been working on high throughput biological image analysis looking for patterns and modeling 3D visualizations, I've been reading about computer vision. Beside the beauty of mathematical formulations for image processing, I found many related papers about robotics and the impressive development of robots which a specific use.

Reading this Gizmodo article I noticed the Hirose-Fukushima Robotics Lab at Tokyo Tech, check the movies section for examples of their fantastic robots like this:



I always like the robots in SciFi, from R2D2 to Megatron, but when you see the actual research in robotics, you can believe in a close future we'll have more sophisticated robots (complete robots, not only robotics arms or autonomous vehicles).

No miracles

Last weekend I saw this cartoon printed in a T-shirt at the PSC, and last day Kbyte's twitts reminded it to me.

Old computers Dream

I own a little old laptop (it was owned by a very good friend, traded in a perfect time for us). It's a HP pavilion ZT1114, PIII @ 1GHz, only 256 Mb in RAM, no battery, I recently change the HD. The computer is still working well, except for versions of heavy Linux can run but response time is slow.

Long time I used in this machine Mandriva, from 2007 to 2009 releases, changing the default desktop to XFCE to save memory and optimizing the system, also I tried Puppy Linux and other minimalistic Linux distributions. But always I feel something missing, an ultimate Linux distro with fast performance.

Until few weeks I noted the new release of DreamLinux, a Debian based distro with a pretty and fast desktop (XFCE). I had installed last week and after one week of use, I like it!
  1. Everything works well.
  2. The AWN bar looks like MacOS X.
  3. The Debian stability and large collection of packages.
  4. EasyInstall application is really useful.
  5. DCP-Control panel works well.
Of course not everything was perfect:
  • The first time I installed it, the main user account wasn't created with the correct configuration, so I logged as root, created a new user again and used it.
  • This new user, I added manually to sudoers list.
  • Wicd cannot use my WiFi configuration, it never connect to my router, so I wrote a shell script to activate my network.
This kind of problems scares a newbie, I could resolved, but other people just format the machine.

Hitler disappointed with OpenGL

This a video so geek, but it's funny (if you known about OpenGL dev).
