Exec summary: RabbitMQ, Java/Android, machining RepRap parts, Linux kernel compilation.
Not everyone was in time for the meeting, but we had a full quorum just in time for the important vote. The night was bitingly cold. In spite of that, the folks congregated in the couches around the meeting table was quite numerous. The vote was a resounding YES. We are moving!
qzio and Emma could supply details about the ReST architecture talk. Over some fastfood, Olle expressed interest in RabbitMQ, a hip and trendy piece of software. phrst made it clear that he’d been using it successfully at work for two weeks, and declared that he could explain it. Turns out: he could. In minutes, we were following a Python tutorial, learning the concepts. See Part One, part two, and part three. An impressive piece of working Erlang culture, allowing great simplification of software. “It has grown so much in the 14 days I’ve known it. Used to be that there was only the AMPQ specification document. Now, there’s this whole documentation culture.” Two weeks, and already a veteran of a software subculture.
The work to create a turn-key, one-stop, ActionScript-to-Java package continues. StG and jonasb were heard talking about their stack, which involves Visual Basic and ActionScript that generates Java. And on the other hand: Java.
The RepRap machine had fallen down from its table, perhaps last Friday. It had taken some physical damage. Five (5) parts were in need of replacing, and phrst wielded the drill-press carefully, slowly making new pieces. Bootstrapping using a knock-off Dremel.
In other news: Today marks the one-year anniversary of the goodwill-generating, member-attracting, community-strengthening, hardware-donation-inspiring police raid. Please do click randomly to read more about that. Innovation and tech culture continues unabated.
We also had Extreme Cola in abundance.
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.
