URGENT: Google Summer of Code 2007 - Help needed
by Giovanni Corriga 03 Mar '07

03 Mar '07

Hi all Google has recently announced the third edition of its Summer of Code program. In this program Google provides funding to students to work on open source projects. I think Squeak could benefit, both technically and in advertisements, from partecipating in such a program. Unfortunately, the deadlines are pretty tight: - March 12th for Squeak to apply as a mentoring organization - March 24th for students to apply as developers for the program. I'm trying to have Squeak apply to the program. So if anyone would like to partecipate to this effort, either as a mentor, or as student developer, or just to provide ideas and suggestions, please contact me ASAP at my personal email. Ciao, Giovanni

Looking for old Smalltalks for DOS
by Aaron Reichow 03 Mar '07

03 Mar '07

Hi! This a call for old versions of Smalltalk. I used to have a couple of them, and feeling the urge to see if they work in DOSbox on OS X, I having tried in vain to find them. I did find my copy of Smalltalk/ V 3.0 for DOS and use a computer at my wife's work for this purpose to copy files off the 5.25" disks, and it works! This is a graphical version of Smalltalk for DOS that doesn't work well in DOSbox, perhaps problems with EGA drivers or something. But I did have another version of Smalltalk for DOS that worked entirely with text windows, though I can't remember the precise name/version of the software- Smalltalk/V 286 perhaps? Anyway, if you have a copy of this, could you please send it my way? In addition, I am very interested in any old version of Smalltalk for various OSes, though only for Mac and PC hardware. I'd love to see a real version of Smalltalk-80 running on an old Mac, for instance. Please email me if you can help me out with this! Regards, Aaron

[ANN][Squeak-dev Image] Version 83
by Damien Cassou 01 Mar '07

01 Mar '07

Squeak-dev image is an image made for squeak developers based on Squeak3.9-final-7067. If you use it, please tell me. You can download it here: http://damien.cassou.free.fr/squeak-dev/ Changes in this version: ------------------------------ - Finally add connectors (sorry for this package) - Prepare Browser Booster - Add a new shortcut to KeyBinder : CTRL+k opens a Workspace (a Shout workspace if installed). - RoelTyper is now downloaded from SqueakSource - Prepare LambdaMessageSend - Bad comment in Connectors - Add example for DebugReport and Sixx - Change minnow.cc.gatech.edu to wiki.squeak.org As usually, all installed packages have been updated. Prepared packages: -------------------------- There are a lot of packages prepared for you in this image. They are not loaded in the image, but they can be easily: - Open ScriptManager (world->open...->Script Manager). - Go to 'Prepared packages' folder (on the left). - Select the package you want to install. - Click the link at the very bottom of the text. Future work: ---------------- - Wait for feedback. - Use Lex Spoon's universes instead of prepared packages. - Base squeak-dev image on Keith Hodges 3.9.1. - Try to pre-download prepared packages (I tried but don't know how to use Monticello like this) Please tell me what is your experience with this version. Please tell me what you want for this image, this is for you. -- Damien Cassou

packaging style requests
by Lex Spoon 01 Mar '07

01 Mar '07

I have two requests for packaging style, after having delved through 100+ packages for the 3.9 stable universe. First, SAR's with fancy load-time scripts are often too smart for their own good when used in a package universe. A particular example of this is load-time options. Instead of having a single SAR with a load-time option, I wish people would divide the package into smaller packages. Then people can install precisely the component packages they want. As an example, if package Foo's tests are considered optional, then just make it two packages. Post Foo and Foo-Tests, where Foo-Tests depends on Foo. Second, we have a lot of readme windows popping up. A readme popup is very friendly if you are installing 1 package. However, with a package-browsing tool, it's not uncommon to install 5 or 10 packages at a time. When you do so, you end up with more windows than the user can possibly pay attention to. I was installing 100 at a time recently, and the result was just comical. I would like it if we had a registry of readme's, so that packages do not clutter up the main screen just to announce they are now loaded. This would help at package-loading time, and also it would mean people can actually find this documentation again weeks later after the package is installed. Barring such a tool, how about we limit ourselves to one readme per program? You an always add hyperlinks to the other ones. Okay, that's my wishes. Do with them as you will. Happy Squeaking, all! I've had fun browsing through all the great things everyone has posted. -Lex

Profile with fork
by Frédéric Pluquet 01 Mar '07

01 Mar '07

Hello, I want profile my work to find how reduce the execution time. In my framework I do a lot of fork, creating processes. When I profile, via MessageTally spyOn: [], only the "active" process (the father) is profiled and I don't have any information on the subprocesses :-( Is there a simple way to resolve my problem ? Must I use an another tool ? Thank you for your future answers, Fréd ___________________________________________________________________________ Yahoo! Mail réinvente le mail !

RE: Exporting Namespaces

+1. Just please, no colons.

[ANN] Exupery 0.11 released
by bryce＠kampjes.demon.co.uk 28 Feb '07

28 Feb '07

This release contains: * primitives for #new and #@ * ExuperyMethodContext (allows full debugger support for compiled code) * interrupt checking (allows Alt-. and profiling to work inside compiled code) Installation instructions are here: http://wiki.squeak.org/squeak/3945 The new primitive only works for pointer objects with less than 64 instance variables and are a fixed size (not Arrays). This covers most uses inside Smalltalk, and the new primitive can be easily generalised when there's a benchmark that requires it. Here's the benchmarks: arithmaticLoopBenchmark 1387 compiled 127 ratio: 10.920 bytecodeBenchmark 2139 compiled 484 ratio: 4.419 sendBenchmark 1582 compiled 728 ratio: 2.173 doLoopsBenchmark 1063 compiled 843 ratio: 1.261 pointCreation 1075 compiled 1030 ratio: 1.044 largeExplorers 585 compiled 595 ratio: 0.983 compilerBenchmark 474 compiled 454 ratio: 1.044 Cumulative Time 1058.337 com We delayed this release to fix a bug found by Andy Tween that seems to occur frequently on Windows but is cross platform. Thank's to Andy's help the bug is now fixed. And thanks for building the Windows VMs. The next release will compile in the background. Bryce
