To me it looked like it died quickly after all the technical people left to do Qwaq... Now OpenQwaq is GPL, so we will not even think about it as it will make all our thoughts GPL, too.

[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
