Oddness in Delay behavior in Cog...
by Lawson English 23 Oct '11

23 Oct '11

http://pastebin.com/zqhCpxvL In a nutshell: 0 to: 11 do: [:i| myWait := Delay forMilliseconds: i. Transcript show: (myWait asString),':';cr. 5 timesRepeat: [Transcript show: (Time millisecondsToRun: [1000 timesRepeat: [myWait wait]]);cr.]]. delay of 0 => 0 ms delay of 1 => 2 ms delay of 2 => 2 ms delay of 3 => 4 ms delay of 4 => 4 ms delay of 5 => 6 ms etc Not a real biggie, but just seemed odd.

sources.squeak.org down
by Alexander Lazarević 21 Oct '11

http://www.downforeveryoneorjustme.com/sources.squeak.org BTW, if something like this happens and I want to save a local copy of a package that originates from sources.squeak.org wouldn't it be enough to adopt the package from the package cache and save my working copy with this ancestor? I've tried that, but somehow there seems to still be a reference to the version on sources.squeak.org. Alex

New COg VMs available at...
by Eliot Miranda 21 Oct '11

21 Oct '11

http://www.mirandabanda.org/files/Cog/VM/VM.r2502/ CogVM binaries as per VMMaker.oscog-eem.134/r2502 Ensure the unix run scripts set SQUEAK_PLUGINS if unset. Fix remaining bug in context access fixes of VMMaker.oscog-eem.119. stObject:at: and stObject:at:put: need to use stackPointerForMaybeMarriedContext: not fetchStackPointerOf:, since the context's stack pointer may be stale. Fix send trace printing. Interpreter sends need also to be printed. (A better fix is probably to redo sendBreakpoint: but this will serve for now). N.B. this reassigns the sendtrace flag values. Add primitiveNotEquivalent with prim # 169. -- best, Eliot

But if #bitAt: is defined for all integers, then for consistency #bitCount should work for negative integers also. Integers don't really have bits unless you are thinking in terms of the underlying representation, which is certain to be twos complement in any use case that I can imagine. So counting bits in a negative integer should work in the same manner implied by #bitAt:. I am surprised that a method like this does not already exist. But the method finder does not seem to find #bitCount either, so I wonder if some equivalent method already exists somewhere? BTW, tinkerers may enjoy playing with www.squeaksource.com/TwosComplement, which demonstrates bit twiddling in twos complement register arithmetic: 16r0505 bitCount ==> 4 (16r0505 asRegister bits select: [:bit | bit value]) size ==> 4 Dave

Squeak Oversight Board minutes – 10/18/11
by Chris Cunnington 21 Oct '11

Attending: Chris Muller, Bert Freudenberg, Colin Putney, Randal Schwartz, Levente Uzonyi, Jecel Assumpacao Jr., Chris Cunnington Notes on the 4.3 release: - this won’t be the Cog release because of the needs of Linux which might not be aware of a sudden change - Jecel is going to look at Linux distros and the vms they use - Colin will talk to Esteban about multiple versions of the vm and get the OmniBrowser to run on 4.3 - Chris C. will go through the Daily Commit Logs back to the last release to compile a list of changes to the 4.3 release Notes on Package Management ( Or, what would need to happen for Nicolas Cellier to take Complex out of the image?): - The question was discussed if Squeak Map would be used for package management or not in future - In the future Squeak Map may be the tool that lists packages that conform to a series of tests which are a de facto contract between developers and core contributors - If that’s the case, Squeak Map needs some work. But owing to some low profile changes that have already been made to Squeak Map, perhaps not as much as one might expect
