Some pictures from the animal enclosures in the Bavarian Forest national park. Very few pictures sadly because first most animals hid due to the excessive heat, then due to a massive downpour that had me flee the park myself.

The rain was unreal, looked just like a small cloud passing overhead but more and more small clouds came drifting and all got stuck on the mountain range to add to the rain. When I got out, completely soaked, I looked back after 10 km driving in brilliant sunshine and saw a black spot still hovering right over the park...

The Garching Research Center near Munich had its open door night yesterday, so I looked at some of their exhibitions. Quite interesting though it's hard to demonstrate anything of substance in the environment -- there's just too much theoretical groundwork to cover in advanced research. There was one intriguing-looking "quantum violin" that I walked away from because I found it impossible to understand the required theory on the spot, late at night.

Microsoft has open-sourced WorldWide Telescope, a .NET application that aggregates global astronomy imagery into guided tours and whatnot. I haven't used it myself, in fact I was quite unaware of its existence, but it sounds rather interesting.

The upcoming Java release 8u60 finally fixes Windows DPI scaling in JavaFX with fully automatic coordinate and image scaling, same as in WPF and browser display engines. This resolves the biggest deficiency JavaFX had as a desktop GUI framework.
The upcoming Java release 8u60 is set to finally fix the JavaFX DPI scaling issues on Windows that I described back in August 2013. To recap, JavaFX would scale the default application font to the ...

The core with only rudimentary shell regions were found in the New Zealand kea, representing one of the only living species at a basal divergence with all other parrots, implying that parrots evolved vocal learning systems at least 29 million years ago.

There was nobody around to teach them "Polly wants a cracker" back then, though.
 
Activity mapping of Psitticine brains suggests a song system embedded within a song system, a network nesting which was not identified in other avian vocal learners (i.e. Passeriformes and Apodiformes).

For any fellow academics that have been frustrated with manual re-extraction of data from their .bib file for CVs, reports, web sites, etc:

Parsing BibTeX into S-Expressions, JSON, XML and (back to) BibTeX with Racket: http://matt.might.net/articles/parsing-bibtex/
BibTeX is a tool for managing and automatically generating bibliographies when using the TeX/LaTeX document preparation system. It takes much of the tedium out of the process of writing and formatting bibliographies. At the heart of BibTeX is a plaintext .bib file with entries like: ...

Electron microscope video of phonograph needle in an LP groove. About 1/400 actual speed. Captured via Tektronix MDO3000 oscilloscope.

This video was made via the "stop motion" animation technique.  I moved the LP by 50 microns at a time, and captured a frame after each move. The setup inside the microscope was made possible by the fact that there are two separate stages with their own motion controls. I fixed the needle to one stage and the LP to the other so that I could get both parts into the frame at a good angle.
