[Pharo-project] [ANN] Sqnappy - a fast compressor wrapper

by Masashi UMEZAWA

Hi all, Recently I've developed Sqnappy - Squeak/Pharo binding of the snappy compressor library. https://github.com/mumez/sqnappy About snappy: https://code.google.com/p/snappy/ Sqnappy is easy to use. You can just send #compress:, #uncompress to SnappyCore: compressed := SnappyCore compress: data. uncompressed := SnappyCore uncompress: compressed. With a simple test, Sqnappy was 10.8x faster than the existing GZipWriteStream/GZipReadStream. Additionally, Sqnappy implements snappy framing format, so that it can treat big data with a small memory allocation. About framing format: https://code.google.com/p/snappy/source/browse/trunk/framing_format.txt Tested from a workspace, 1.3 GB pg_dump file was compressed in around 10 seconds and decompressed in 6.5 seconds . No annoying GCs. It was comfortable. Enjoy! -- [:masashi | ^umezawa]

Re: [Pharo-project] Pharo 3.1 meeting

by Sean P. DeNigris

Does "update the monkey" refer to Penelope? I was going to ask whether we can start using the Penelope issue urls e.g. in the "[update 3.0]" posts, but then I checked the Penelope pages for the #30059 issues and: http://bugs.pharo.org/issues/id/10367 http://bugs.pharo.org/issues/id/10389 were two days behind the actual issue And http://bugs.pharo.org/issues/id/10356 reported 'MessageNotUnderstood: receiver of "joinUsing:" is nil'. Where is the Penelope code? Maybe we could help... didn't see it on sthub... Slightly OT, in the "[update 3.0]" posts, it'd be helpful to list the diffs under the issue they belong to instead of all together at the end. I.e. url1 diff1a diff1b url2 diff2 url3 diff3 instead of url1 url2 url3 diff? diff? diff? diff? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Pharo-3-1-meeting-tp4683613p4683644.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
