[Pharo-project] About sqnappy and LZ4
by Mariano Martinez Peck April 18, 2013

April 18, 2013

Hi, I was checking https://github.com/mumez/sqnappy. Some time ago I wrote bindings for LZ4: http://smalltalkhub.com/#!/~marianopeck/LZ4 Do you know which are the differences? It looks both are intended for the same purpose: speed in decompression/compression over compression ratio. From what I can see in http://fastcompression.blogspot.fr/p/lz4.html it says encoding 555 MB/s decoding 1.80 GB/ while in https://code.google.com/p/snappy/ it says "Snappy compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec or more." So...doesn't LZ4 seem to be faster than sqnappy? And I already wrote the bindings for LZ4...so I was wondering that... Best regards, -- Mariano http://marianopeck.wordpress.com

[Pharo-project] Issue 10219: Completion: enter on accept awkwardness
by Sean P. DeNigris April 18, 2013

April 18, 2013

From https://pharo.fogbugz.com/f/cases/10219/Completion-enter-on-accept-awkwardn… : > The combination of enter on accept, with the current behavior to select > the first completion suggestion by default = trouble. For example: > > 1. Type "printOn: aStream"... pretty common method start > 2. Hit enter to go to the next line > > You will now have "printOn: MCDataStream" WTF!! I get burned by this > pretty regularly and it's annoying. I'm not sure what the fix should be... > probably no default selection in the suggestion menu, but possibly only > when enter on accept is enabled (t would require an extra key press to > complete and when do you ever type a tab in the middle of a line?) ----- 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.

[Pharo-project] the fun theory
by Torsten Bergmann April 18, 2013

April 18, 2013

I read about this game today. It is written in Lua and one can play the game by editing Lua scripts (in an external editor) to optimize trains for transportation: http://trainsportedgame.no-ip.org/index.php http://www.youtube.com/watch?v=yFKZd8nEQyA This game combines learning and playing and is a nice attempt to get people into coding. Maybe we can raise the Pharo fun factor by getting people into something similar...

[Pharo-project] Xtreams's FileDirectory dependence
by Frank Shearar April 18, 2013

April 18, 2013

Xtreams depends on FileDirectory in at least three places, all in the Xtreams-Terminals package. (Three messages on FileUrl, #appending, #reading, #writing; two tests in XTFileReadingWritingTest >> #setUp and #tearDown) Pharo 2.0 has no FileDirectory. So it seems like the easiest (not necessarily simple, nor right) thing to is to break that out into Xtreams-Terminals-Squeak and Xtreams-Terminals-Pharo packages, and similarly for the tests. After that, we'd need to adjust the ConfigurationOfXtreams. I think I forgot to fulfil a promise to submit an updated version of this that loaded FFI correctly (sorry!). Thoughts? Do any Pharo folk load Xtreams? frank

Hi, IÂ´m searching for Options to visualize diagrams, for example an class-diagram. Is there an graphViz-Implementation in Pharo or better other Options to display Diagrams? (here is the graphViz-Dot-Example: graph ethane { Car -- tire1 [type=s]; Car -- tire2 [type=s]; Car -- tire3 [type=s]; Car -- tire4 [type=s]; } Thanks for routing me in the right direction!
