Really free chemistry books
With pleasure I read Analogue or Digital? - Both, Please. Funnily, I just created MP3 (or, preferably Ogg Vorbis, superior but hardly any support by commercial companies, who rather seem to pay license fees) directly from the CD.

VRMS meme: how much non-free software are you running?
Over at Planet Ubuntu there is a meme running around VRMS (Virtual Richard M. Stallman, brilliant name!) which finds non-free software on your desktop. I uninstalled Sun’s Java6, for which there is the OpenJDK6 alternative.

Bioclipse, RDF and defeasible reasoning
Well, I have yet to read the paper in detail, but my new student Samuel is going to work for 20 weeks on defeasible reasoning with DrProlog in Bioclipse.

Open Chemical Data #1: NMRShiftDB
As I reported earlier, progress is only possible of you can modify and redistribute. This is why Open Data, Open Source, and Open Standards are so important to us Blue Obelisk members. For data, proper licensing makes these two requirements possible, but more importantly, make those rights explicit. Rich is running the nice Zusammen blog, but most of his entries are not Open Data. Even larger chemistry data repositories can be vague and have seemingly contradicting statements.

The Art of Programming: do not leak implementation details
At the JChemPaint workshop here in Uppsala, where we have Mark from Chris’ group as our guest, we encountered an inconsistency in CDK 1.2, where the bond stereochemistry did not yet follow the pattern recently adopted of having Class fields, to allow using null to have the semantics of undefined. Previously, the defaults for native values were confounded with set values. For example, the formal charge unset and 0 would be have a field value int = 0.

NMRShiftDB RDF #2: Some statistics
This morning I had some more fun, and since the statistics view on the NMRShiftDB server is down, I though I could recalculate the statistics myself. Because the current RDF version of the data does not include all information yet, I cannot reproduce all of them. On the other hand, I can determine some other interesting statistics.
