Using BioLux NV microscope in Ubuntu Linux

Using BioLux NV microscope in Ubuntu Linux

I recently got a Bresser BioLux NV microscope. Of course it is quite cheap and you get what you pay for. I'm still very pleased with it because it is a fun toy, and I'm not afraid to destroy something by not treating it properly. I'm also happy that the cam works well with Linux.

Ubuntu Linux 10.10 on Samsung NP-R540

Ubuntu Linux 10.10 on Samsung NP-R540

I recently bought a cheap Samsung NP-R540 with an ATI Mobility Radeon HD 4500. Ubuntu 10.10 installed smoothly. I encountered two problems: The comercial ATI-video driver did not want to install, so I switched to the free driver and I'm happy since. The Touchpad does not work well for me in multitouch-mode.

Usage of hg commit –date (mercurial)

Recently, I was trying to move some stuff from RCS to mercurial. There does not seem to exist a converter and since it was only a few revisions, I decided to do it by hand. The problem arose how to set the commit date manually and google yielded a nice blog post that answered my question (refering to the formidable but less searchable hgbook).

Makefiles for LaTeX

Makefiles for LaTeX

This entry was originally submitted to Debian Package of the day, but rejected because make is well known. Figure 1:The file In is used to produce InterM that is itself used to produce Out. Therefore Out depends directly on InterM and indirectly on In. I agree that most programmers and administrators know GNU make. Sadly, it is ignored by most others. GNU make solves a very common problem that everyone faces when processing more than one file with more than one programm. It keeps track which file has been changed and which files have to be regenerated.
