At least you can read the bytecodes created by squeak in the current image: Open a browser in Squeak and select a method in a class. Right click on the methods name in the method pane and select "What to show..." and "byteCodes". Have fun, Torsten

Progrmaming in Bytecode?
by Aaron 31 Jul '02

31 Jul '02

Hello! I know this may sound sadistic, but how could I go about programming in Smalltalk bytecode, directly? I've seen assemblers for Java, that do the same job as assemblers for native CPUs. I imagine such a tool doesn't exist for SMalltalk at this time, but perhaps it wouldn't be hard to put one together in my quest to play with bytecode. How could I write methods in bytecode directly? I know- it sounds sick. I've never wanted to program any sort of machine language, but today- out of nowhere- I got a hankering to do so. Progrmaming 'machine language' on the SVM seemed like a good place to learn. :) Aaron

SqueakMap crashed but it's up again!

Hi! I think someone from unibe.ch checked it out, Alexandre perhaps? :-) Anyway, I am not sure - Squeak segmentfaulted on me suddenly. But it's up again. regards, Göran

Computer Music in Squeak
by Richard A. O'Keefe 31 Jul '02

31 Jul '02

We have an annual 'Hands-On Science' week in the summer holiday, when high-school pupils from around the country come and try things. There are 'projects' where we have them for 3 or 4 mornings and 'snacks' where we have them for a couple of hours. I received an unexpected request to run another one this coming summer (it's winter here now). It suddently occurred to me that a computer music project using Squeak should be really fun, but I've never done anything like that. Any suggestions would be MOST welcome. It may not come off, but if it does it should be quite enjoyable for the students. We'd probably have a lab of OS/X macintoshes, if it makes any difference.

External processes from Squeak

Hello, Is there a way to execute an external process from squeak and get its input, output and error streams? (something like popen() ) Yoel

Hi With John's suggestions I've rebuild a new mac package with the newest VM and the plugins in ftp://st.cs.uiuc.edu/Smalltalk/Squeak/3.2/mac. Someone want to give it a try? thanks! cheers bruce

Antialiased Fonts on 3.2
by Russell Allen 31 Jul '02

31 Jul '02

Hi everyone, I'm not sure whose project this was (Henrik's?) but I was wondering whether the aa font support described at page 1225 of the swiki had been updated for 3.2 by anyone; in particular whether anyone has support for coloured (ie not black) antialiased fonts... I managed to force the 2.8 changeset to install on a clean 3.2 image, but don't know enough about font support to know what (if any) damage it may be doing to the rest of my system - it certainly seems to be breaking a lot of stuff in the FileList. On the other hand, it sure looks pretty on my iPaq... Russell

Re: New Random Number Generator
by Mark4Flies＠aol.com 31 Jul '02

<< Hmm. Have you compiled the C code and tested it? Just in case... it wouldn't be the first time that demo C code had some subtle mis-print in it. >> Yes, I copied the C source file from the Mersenne Twister (MT) Web site into Project Builder on Mac OS X. It ran with out any error. I took the 1000 numbers and brought them into JMP for statistical analysis. They looked great. (JMP random number generators are based on this same MT algorithm now.) << To check further, knock up a little C prog to take a few numbers and do the various shifts/masks, and some Squeak code to do the same. Compare; it should at least illustrate where the differences are creeping in ot bite you. Chances are good that it is a single trivial typo-like error somewhere. >> Thank you for the advice but now I suspect that it is probably not a typographical error (confirmed original C source) but a subtle difference in the behavior between Smalltalk and C when it comes to long unsigned integer operations. I just have no clue! Again, thanks Tim for looking at this problem for me. -Mark
