Hi, Some of the things that got mentioned last week...
Instagram wrote earlier in the year how the RDBMS Postgres has managed to keep pace with their growth. http://instagram-engineering.tumblr.com/post/40781627982/handling-growth-with-postgres-5-tips-from-instagram "Camlistore is your personal storage system for life." A 20% project by some Googlers. Now reached version 0.5. "Content-Addressable Multi-Layer Indexed Storage". (Came up in relation to Terry's "Open Source Document Management Tools" thread.) http://camlistore.org/ Unicode has combining diacritic marks̆̇̈. The Supercombiner is lots of them together to see how well the renderer, e.g. browser, copes. http://sbp.so/supercombiner Unicode's Right-to-Left Override. http://xkcd.com/1137/ An individual cell in an FPGA is based around a look-up table mapping its inputs to outputs to implement a Boolean expression. http://www.fpga4fun.com/FPGAinfo2.html The π filesystem sounds like a nice idea, don't store a file's bytes, instead store the offset of where its bits appear in π and the length, and store this metadata instead. I think the implementation seems lacking; the file's content is turned into multiple (offset, length)s, one for each *byte*. The metadata is larger than the source. :-) https://github.com/philipl/pifs Tim Waugh wrote vtgrab some years ago. It allows monitoring of another machine's VTs (virtual terminals). http://cyberelk.net/tim/vtgrab/ The Menger sponge simultaneously exhibits an infinite surface area and encloses zero volume. Might take some time to 3D-print. https://en.wikipedia.org/wiki/Menger_sponge A third-party's rendering of the UK National Grid's status. http://www.gridwatch.templar.co.uk/ The tall ship Pelican, currently at Weymouth. You can pay to be crew, including for a trip to the Caribbean. Or package off SWMBO as a surprise, Tim. http://www.adventureundersail.com/ Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday, 2013-11-05 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue
