[Pharo-project] Integrating Changes in 1.4 that require a new VM
by Marcus Denker Sept. 23, 2011

Sept. 23, 2011

Hi, There are two changesets waiting for integrating in 1.4 that have serious consequences: - Ephemerons. The VM level changes are in the Cog VMs build on Jenkins, but have not been integrated in the VMMaker codebase. http://code.google.com/p/pharo/issues/detail?id=4265 - Finalization code checks for #hasNewFinalization This is true in the current VMs build in Jenkins, but in older VMs this is not in. http://code.google.com/p/pharo/issues/detail?id=4483 There are two options: a) integrate in b) not integrate it a) means that the image runs on older VMs, too. b) means we accept that we can never improve anything for real. There will be more changes coming... e.g. imagine we have a Vector Graphics Canvas as some point next year... what will we do? use it or not use it to stay compatible?

The main goal of MPFR is to provide a library for multiple-precision floating-point computation which is both efficient and has a well-defined semantics. It copies the good ideas from the ANSI/IEEE-754 standard for double-precision floating-point arithmetic (53-bit significand). (I think I asked that questions once alrady...)

[Pharo-project] Clarifying and optimizing Integer>>asFloat

It's too long for a mail, but all explained here: http://smallissimo.blogspot.com/2011/09/clarifying-and-optimizing.html Optimizing such kernel message is important - for example when reading a file of floats... Which version do you prefer ? Shall comments be that long ? Any other opinion ? Nicolas

[Pharo-project] Smallspaces - Tuple Space for Smalltalk
by Dave Mason Sept. 22, 2011

Sept. 22, 2011

There is a reference on Wikipedia's page on Tuple Spaces to http://www.fongen.no/?docname=SmallSpaces/ but that is a dead link. I was interested in building tuple-space for Smalltalk, but this and a 1988 paper from Matsuoka and Kawai are the only things I turned up. If anyone knows more, please let me know. Also, I'd be interested to hear if people think this is a particularly good idea before I turn a grad student loose on it. Thanks ../Dave

[Pharo-project] jenkins cog - slow monticello on osx
by Tudor Girba Sept. 22, 2011

Sept. 22, 2011

Hi, Since a couple of weeks I am working with the Cog VM built on Jenkins: https://ci.lille.inria.fr/pharo/view/Cog/job/Cog-Mac-Cocoa/ Here is a little feedback. It worked quite well, the only problem is that Monticello is really slow in the Moose image. This means that even opening the Monticello Browser takes several seconds. I thought that this might be induced by something in the Moose image, but if I try with the Elliot's VM (2489), it works blazingly fast. Cheers, Doru -- www.tudorgirba.com "The coherence of a trip is given by the clearness of the goal."
