Not so long ago, it was decided that KDE 4.0 will use SCons as a configuration and building tool, instead of the autotools and make: the common ./configure && make && make install which has served the open source community very well for so long. SCons is different in several ways.

Yesterday I reviewed an article which published a QSPR model which looked something like: \[y = 151 + 50p1 - 12p2 - 0.006p3\] with quite OK prediction results (R=0.9880). But I was not quite comfortable with the coefficient for the \(p3\) variable. The article did not calculate significances for the coefficients, so it was not obvious from the article wether is was useful to include them. I then looked at the range for p3, which was 110-150;

The great thing about open source is that… it’s open. When I was browsing the internet just now, I dropped in on KDE Dot News. In the rightside column, there is a feed of new KDE software from KDE-apps.org. A new version of my favoriate music player, amarok, lured me to the KDE-apps website, where I saw rkward is latest announcement.

I just read that the Kubuntu team wants to include Kat in the dapper release (scheduled for April 2006). Kat is (to be) the KDE equivalent of Google’s desktop search bar. This is great news for us chem-bla-icians, as Kat has support for full text searching of chemistry files! Let’s see if I can get the Kubuntu team to package up kfile_chemical too, which will extend Kat (and KDE in general), with extraction of meta data from chemical documents.

Some time ago Rajarshi Guha introduced R bindings for the CDK (see his CDK News articles), and today I tried to install his rcdk package that makes it happen. However, it requires SJava which compiled fine on other machines, but not on my AMD64 machine. The problem seems to be related to the GNU GCC 4.0 compiler I have installed.

On the 7th International Conference on Chemical Structures Jeroen Kazius has a poster on finding discriminative substructures, that is, molecular fragments which can be discriminate between two acitivity classes. The software is released as Gaston , is written in C++ and has the GPL license. Later I encountered MoSS which has the same goal, but uses a different algorithm.

Most Dutch chemists have their annual Lunteren meeting, so do I. Lunteren is a small village on the Veluwe where nothing much can be done, except for listening to the presentations. I participate in the Lunteren meeting for analytical chemists, i.e. HPLC, MS, GC and all their combinations upto and including HPLC/MS/MS, and since a few years the Lab-on-a-Chip stuff.

Just finished applying the latest spelling error fixes to CDK News 2.3 . Took me some three hours to finish it up the 12 pages, which has mostly to the need to recompile the PDF after each change to make sure that nothing in the layout got broken.

Jerome Pansanel contributed new patches for kfile_chemical; on Monday actually, but I have been busy with other things, among which a presentation I have to give next Monday for some 100+ analytical chemists. The patch adds support to KDE for five new chemical MIMEs: XYZ, Mol2, SMILES, VMD and GenBank. Therefore, I just released a new version (0.10), and added an announcement to Freshmeat.net.

Today is my 31st birthday, nearing half-point now (statistically seen). Also, by now I should have had my scientific moment of glory, otherwise I can forget that Nobel prize. Oh well, forget it. Have you seen those small advertisements on this page (RSS users, please visit the website :)? Funny links they give. The system is very nice btw: it awaits google indexing of the blog and then decides which ads are relevant.
