I have an "on again/off again" relationship with treemaps. Lately, I've been taking another look, partly inspired by Björn Engdahl's MSc thesis Ordered and Unordered Treemap Algorithms and Their Applications on Handheld Devices.

Something a little different, my dad's work features in the Winter 2008 issue of Art News New Zealand by Rob Garrett, who has a copy of the article on his web site. Dad designed eight stained glass windows for Westlake Boys High School in Auckland, New Zealand. Rob Garrett describes them thus:They are gorgeous to look at (the picture below shows them before they were mounted in the school hall).

As much as I like the idea of a globally unique, resolvable identifier, my recent experience with JSTOR is making me wonder.JSTOR has three identifiers for articles it archives, DOIs, SICIs, and stable URLs (the later being introduced with the new platform released April 4, 2008). Previously JSTOR would publish DOIs for many of its articles.

BioOne sucks. Really, really, sucks. I have lost count of the number of times they break DOIs. These are supposed to be the gold standard globally unique identifier, and BioOne continually buggers them. For example, take this URL:http://www.bioone.org/perlserv/?request=get-abstract&doi=10.1600/02-14.1.Note the doi=10.1600/02-14.1 bit at the end.

Partly inspired by Pedro Beltra's post Open Science project on domain family expansion about using Google Code as a project management system, I've started to populate the iPhylo project. At this stage I'm uploading some scripts for parsing and extracting bibliographic records, and adding wiki pages describing how this is done, discussing different bibliographic identifiers, etc.

MarkMail is a great tool for searching mail archives. Although focussing on software development projects, they are open to requests, so last week I asked if they could index TAXACOM.

I've just discovered Nicolas Garcia Belmonte's JavaScript Information Visualization Toolkit (JIT). Wow! This is very cool stuff (and no Flash). To quote from the web site:Nicolas also links to a talk by Tamara Munzner, which I've embedded below to remind myself to watch it.

Trivial as this may seem, I'm trying to find out who designed this "Open Access" logo, and whether there are some original files for it. I've seen this logo (or variations on it) on the PLoS web site, the open access publisher Hindawi Publishing, and the Mac OS X program Papers uses it.It's driving me nuts that I can't find the original.

The more I play with GBIF the more I come across some spectacular errors. Here's one small example of what can go wrong, and how easy it would be to fix at least some of the errors in GBIF.
