Precompiled Cog VM for MS Windows
by Hannes Hirzel 30 Aug '10

Hello Where do I find a precompiled Cog VM for MS Windows? http://ftp.squeak.org/Cog/ does not contain it and on www.squeak.org I do not find it either. Regards Hannes

Perhaps somebody would be willing to show a piece of code written in a functional style? This was presented but then quickly dismissed: Smalltalk at: #square put: [: x| x * x ] Chris

Date[And]Time fractional seconds printing
by Andreas Raab 30 Aug '10

30 Aug '10

Hi - I've noticed a while ago that at some point in the evolution of Squeak both Time as well as DateAndTime had "nano seconds" added. Unfortunately, the default printing of both of these classes leads to some extremely strange effects now. For example, where historically something like DateAndTime now asUTC. would print "2010-08-18T23:23:54+00:00" it now prints silly nonsense like this: "2010-08-18T23:17:49.888000007+00:00" (I just found this in one of our log files). Similarly, if you evaluate "Time now" you get results like "4:22:07.369 pm". In short, the question is: Is there any point whatsoever to print fractional seconds by default? It seems to me that if you need to print fractional seconds you might as well use some other selector and leave #printOn: with the historical behavior of not printing fractional seconds. Anyone in favor of preserving fractional seconds by default please raise your hand and provide some arguments why such behavior would be preferable. Cheers, - Andreas

Experimental Cocoa OS-X based Squeak Cog JIT VM 5.8b4.
by John M McIntosh 30 Aug '10

30 Aug '10

I've stuck a version (5.8b4) of the cocoa based os-x squeak cog JIT based VM in my experimental folder. http://homepage.mac.com/johnmci/.Public/experimental/Squeak%205.8b4.app.zip I spent the last two days becoming very familiar with Open/GL and rewrote the display logic to use Open/GL. I am still doing some further optimization, but people should test this version and let me know what they find. Other Fixes. I think the control-arrow keys should work now, someone test this and let me know. -- =========================================================================== John M.

Running a fresh Squeak4.2-10382-alpha on your latest 5.8b4. Cool! Can now resize the window to extend all the way to the right of the third monitor. Have 30" (2048x1280), 20"(1280x960), 20"(1280x960). Not sure what the logic is that it uses to decide which monitor to fill when you click the green '+' button. Seems like if the left hand side of the Squeak window is on the left screen, and more than a certain amount is on the middle screen, it resizes to the middle. If the right extends to the right of the right screen, it resizes to the right screen unless the left hand side of the window is closer to the left side of the left screen, then it resizes to the left. Doesn't seem to make complete sense. Full screen on in Squeak World/Appearance seems to follow the same logic for which screen to end up full screen on. More than likely I suppose this is OS determined. Yes, get the artifacts when resizing the Squeak window. At least they go away when operation is complete. Anything in particular you want me to try?

Are there any tests we could do to see the improvements? You can use the frame rate morphic to observe the rate rate you get in your application, compare to 4.x. Comparing to a 5.7 in 64bit mode may not be fair because with the same open/GL code it does a frame rate 25% better. I'm also interested in any drawing issues, yes it does lose it's mind when you resize the window (I might fix that someday), but I'm more concerned about drawing artifacts & visual differences between it now and 4.x -- =========================================================================== John M.
