Re: [Pharo-project] About sqnappy and LZ4

by Masashi UMEZAWA

Hi, Actually, I have never noticed that you have LZ4 bindings already. It is indeed a great news! I would never have started sqnappy if I knew the fact. As you say, the project has a similar goal. Anyway, it is good to have another option. Some Sqnappy characteristics: - it has a minimum dependency (it does not use FFI, NativeBoost) so that it can be run on older images - Streaming format support (to be soon) - you can compress very big data with relatively small memory footprint. Best regards, 2013/4/18 Mariano Martinez Peck <marianopeck(a)gmail.com>: > Hi, > > I was checking https://github.com/mumez/sqnappy.

Are there any objections to the last suggested set of default preferences? If not, maybe those should be included as well - but not worth holding up Johan's change, which is essential. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Issue-10219-Completion-enter-on-accept-awkwardness-tp… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
