Re: [Pharo-project] Alien Plugin for Linux

by Henrik Johansen

Uhm, this method (and many others in the extensions-category) have been present in their expected-by-Alien form in Pharo since at least 1.0 Probably a better idea to separate the Alien-"Core" into two packages, one which is actually needed, and one which you only need to load in really old Squeak/Cuis images in order to have it work. In which case you probably won't have method trailers either, and generate: #(0 0 0 0) is the proper extension. Come to think of it, you probably have to go back to pre-closure enabled for that to be the case, with the amount of platform support for alien vms offered back then, it might not be a bad idea to just ditch it entirely.

Re: [Pharo-project] Alien Plugin for Linux

by Fernando olivero

A question to the Ocean developers, why do have a particular Alien-Core package in the ocean repo? ( Alien-Core-LucFabresse.64.mcz ) Are there some fixes that could be included in the official package? Please let me know so i can integrate them. I'm asking because i'm cleaning a bit the Alien mess, ( see previous mail) , and would like to have a single working official Alien.

[Pharo-project] Updating the Alien Squeaksource page

by Fernando olivero

Hi John , could you please update the Alien squeak source web page. Gofer new url: 'http://www.squeaksource.com/Alien' ; addPackage: 'ConfigurationOfAlien'; load. Then evaluate the desired group/s: ConfigurationOfAlien loadCore. ConfigurationOfAlien loadTests. ConfigurationOfAlien loadLibC. ConfigurationOfAlien loadMacOSX. ConfigurationOfAlien loadVMMaker. ConfigurationOfAlien loadWin32. Should be changed to Gofer it squeaksource:'MetacelloRepository' ; package: 'ConfigurationOfAlien'; load. Then evaluate the following to get the default installation (Smalltalk globals classNamed: 'ConfigurationOfAlien') perform:#loadLatestVersion. Or evaluate the following to get more specific group/s: ConfigurationOfAlien loadCore. ConfigurationOfAlien loadTests. ConfigurationOfAlien loadLibC. ConfigurationOfAlien loadMacOSX. ConfigurationOfAlien loadVMMaker. ConfigurationOfAlien loadWin32.

Re: [Pharo-project] Statistic tools in Pharo

+ octave scilab R_lab etc... If you want to give a try on reinventing the wheel, I have a functional interface to Linear Algebra BLAS/LAPACK in VW and Dolphin. Unfortunately, this so called Smallapack interface is not functionnal in Squeak (vm lock & crash expected). Maybe it's worth improving, tell me if interested. This does not handle statistics nor PRNG though...

Hi Alberto, I first need to evaluate my need. There is a number of statistical tools that I need, which at the end may be quicker to directly implement them than relying on an external library (which also comes with its own bag of issues by the way).
