Exec summary: Java/Android & Flash, ReST, CSS optimizer, RepRap cogwheels, radiation detector.
Last Tuesday, we had a full house of developers, hackers, tinkerers, and there was much unlogged activity. The grocery store was all out of Extreme Cola, so we had to resort to julmust and gingerbread as hackfika.
“Just what Is ReST?” Emma asked, and Olle & Emma had an impromptu presentation session, with several ears listening in from the hacking couches. We talked about URLs, and made some examples of URLs-as-interface, and how it can be made readable for humans. When the initial talk-through was done, we went to an online presentation and walked through it. “It was wordier.” All in all, a good time.
(Followup, some forskers went to a talk made by Rickard Öberg at the Jayway office in Malmö, see link for slides.)
How can we build better css compression, can we build something that is aware of what classes are used throughout the site, and minimizes based on that?
Jake and Fredrik built a HTML-parsing CSS compressor, that replaces CSS classes and ids in both HTML docs and CSS docs with shorter ones. Lots of interesting work left looking at how we can work with template-based systems, and with JS parsing…
In another corner, StG and jonasb were working on their high-tech programming project to be able to deploy programs on Java for Android, while developing in Adobe Flash. A program translator, which has a project wiki page.
At times, the sound level increased, when the drill-press was singing its loud song. phrst was building cog wheels and end stops for the RepRap.
Radiation detection: Mia had a sympathy Tuesday at home, hacking her gamma scintillator, it’s fubar :<
The GM-detector was enhanced to almost double efficiency though. A continuation would be an Arduino-based multichannel analyzer.
Background for this project: For more, see an introduction to the science of detecting radiation. For more information on specific detectors see: http://en.wikipedia.org/wiki/Scintillator and http://en.wikipedia.org/wiki/Geiger_counter
For information on Multichannel analyzers (MCA) see Wikipedia’s article. MCA’s are used to plot a spectrum, in this case a gamma spectrum. The spectrum is important for identifying specific nuclides, since every nuclide has a unique “footprint”. A single-channel analyser (SCA) can be used to detect specific peaks e.g. the low energy gamma photons from Plutonium in a plutonium detector. The SCA filters out all other peaks.
That concludes our report. Thanks for reading.
