Hi, I forgot who is maintaining the ubuntu launchpad ppa vm build. But whoever you are ( :) ) would it be possible to include a vm build for the actual ubuntu release utopic unicorn? thanks, Norbert

14353 Delay refactoring (part 2) - change from milliseconds to microseconds
by Ben Coman Dec. 1, 2014

Dec. 1, 2014

The change of Delay from milliseconds to microseconds is ready for human review. (https://pharo.fogbugz.com/default.asp?14353) With this change from milliseconds to microseconds, clock rollover is eliminated, but it seems Delays run at reduced performance. newCodeEnabled FALSE TRUE 128507 101227 delays scheduled per second 100% 79% relative performance 7.8 9.9 microseconds per scheduled delay 100% 127% relative performance I "guess" this is due to the move from 32bit millisecond immediate SmallIntegers to 64bit microsecond boxed LargePositiveIntegers. It would be interesting to check this on Spur64, but for now, is this performance penalty a reasonable trade for eliminating delay clock rollover? The Delay class comment warns of the critical performance its high priority event loop, and on paper a 21% drop in performance seems significant, but actually the main Morph interCyclePause is 50 milliseconds. So... (9.9 - 7.8) / 50000 = 0.004% difference in performance. (Did I get that right?) Comments? P.S.

Re: [Pharo-dev] [squeak-dev] IdentitySet>>collect:

Which defaults to "^self species" and is overidden as required. In the case of Sets, you start with an "unordered collection without duplicates", but since #collect can introduce duplicates, you end up with "an unordered collection with duplicates" --> Bag (per Dave's suggestion) So I think its reasonable that the following two snippets should produce the same result. oc := OrderedCollection newFrom: #( 1 2 3 4 5 ). (oc collect: [ :e | e even ]) occurrencesOf: true. "--> 2" s := Set newFrom: #( 1 2 3 4 5 ). (s collect: [ :e | e even ]) occurrencesOf: true. "--> 2" which you get with the following change...

Woden processor occupation and text highlight
by Yuriy Tymchuk Dec. 1, 2014

Dec. 1, 2014

Hi, first of all let me know where I can write questions about Woden (because I have not seen a lot of activity around it in any chat). Woden and Roassal3D have a problem that when the 3D window is shown, text highlighting is not working. Usually itâs not a big deal, but Rubric writes white text on white background :). I think a problem like that was already in Roassal2 and maybe someone remembers how to solve that? Uko

Woden-GT integration

Hi everyone, I think that during ESUG Woden was integrated into Toolkit in a way, what you can see a 3D visualization as one of the representations of the view. Is there any additional package that provides this functionality? Uko
