An test suite for free, open source JVMs

This weekend I continued my work on getting the CDK and Jmol run with free, open source JVMs. Really, a lot works fine, as reported earlier in this blog: JChemPaint works and Jmol almost works (see the Classpath’s FreeSwingTestApps wiki page), and well over 95% of the CDK JUnit tests run without trouble too. So it comes down to identifying what does not run properly, and file bugs for this. For example, 26101 and 26108. 1 minute read

Tagging blog items

If you have read my previous post and visited that other blog, you might have noted the Technorati keywords . Or tags, really, as explained in this rel=”tag” microformat. Adding them to blog items, will enable indexing by Technorati, one of the bigger blog search engines. So, from now on, you’ll see these tags in my items too, hoping they don’t get annoying. No idea, btw, how blog planets respond to them… For the record, the tags I list below are general for my blog, and not for this blog item specifically. less than 1 minute read

A blog about bioinformatics, semantic web, comics and social networks.

I never got around to mentioning this blog, but YAKAFOKON is a nice blog about, as the titel already says, bioinformatics, the semantic web and social networks. Nice to read, and interesting comments on the function and features of the internet and how they relate to bioinformatics, and science in general. Recommended! less than 1 minute read

Skype on Kubuntu using a Tiptel USB telephone

Because I wanted to test internet telephony I downloaded Skype and tried to get it to work on my Kubuntu system. Unfortunately, the Skype version is only 1.2.0.18, and it does not work well with arts :( That is, using artsdsp it crashes with segfaults whenever I start even a chat, let alone a phone call. This could be worked around by disabling sound in my KDE session, and then the /dev/dsp is open again. less than 1 minute read

Dutch Google News themes messed up

Recently, a Dutch version of Google News was started, and might mean a replacement for nu.nl. I do not like the verbose layout much, because it makes it more difficult to scan headlines. I do like the themes. Except for one. less than 1 minute read

Open source Jmol hits student text book Biochemistry

Today I received news on the Jmol user list that Lubert Stryer’s Biochemistry replaced the proprietary Chime with the open source Jmol. The third edition from which I learned biochemistry in my first year at the university did not feature a CD with live figures, but I am very thrilled to see a program on which I have actively programmed hit a text book I used myself in the past. less than 1 minute read

1D NMR Spectra do not work in QSPR

About two years ago a student started with me to work on the use of 1D NMR and IR spectra in quantitative structure-activity relationship (QSAR) work, with the goal to show that these spectra contain 3D information relevent to QSAR models. It is known that these spectra depend on the 3D conformation of the molecule. less than 1 minute read
