RE: Chess Object problem

Hi Kevin, I'm really glad you asked this question. Because I didn't and here is the response I got! The fix which is referenced above is actually the worst one of all of them (sorry to say that Ron ;-) since it not only uses the non-primitive version (bad for speed) but also adds to the allocation overhead by converting the byte array to a string. And unless I'm mistaken this alone will slow down the chess game by a factor of two (because this code is soooo heavily used in the game). I have actually sped up the whole game by a factor of four (no kidding!) by carefully avoiding allocations in the move generator. http://bugs.impara.de/view.php?id=1879 See the bug for the patch or the chess game is working fine in 3.9b. Now to your questions: > 1) If this is a known problem with a known fix, how > could I have discovered that? Go to www.squeak.org and look at the right side bar at the bottom. You will notice a Bug Reporting link. Go ahead and sign up to Mantis, you should also consider signing up at squeakPeople, and squeakSource. Once there you can query for bugs to see if the issues have been solved. If you are really looking for a solved issue then remember to clear the filter that filters out closed bugs. By querying for Chess on closed bugs you will find the one I reported. As you also found out asking on the squeak-dev or even here is a good way to know. For most of the current development you will find someone that knows. > 2) Is there a way to save/update code from the > debugger? (I made the change in the class browser.) Yes and you have to pause for a second to think about what a wonderful thing it is that changes can be made to a running system. **Pausing to reflect** Ok to change a method in the debugger right click and accept just like anywhere else. Amazing !! > 3) If this is not a known problem, where/how do I make > my fix available for everyone? The best thing to do is attach a change set or Monticello file, fileout or even just paste the code to the bug report and let who ever is the package maintainer look at your fix and decide if it's a good one. Ken will usually come along and assign the bug to someone. The package maintainer will work with someone to harvest the fix into the dev release. That all works in theory unless you mention this on Squeak-Dev. Then what you get is argument about who maintains what, is it an efficient system, why is there only one group responsible for harvesting, and we need more help doing the harvesting. Still that's my recommendation.

do it or not ... that is the ...

Hi evryone, Looking around, I have seen a lote of stuff DoIt, doIt, do it, RBDoItNode and so on... But I wondering what is the aim for DoIt. I mean, that somthing strange is the DoIt seem to be things that bind code to sombody but don't now where...? In fact I was although wondering how methodes are bind to a class. How browser done it[do it:)]? And what is the class for methodes? Thanks Mathieu

self executable with squeak -- pause on startup

Hello First week with squeak :) I have one (really not one:) question. When I start squeak by clicking on squeak.exe, I get pause about 15 sec. Then if in folder only one image file squeak starts with it. If I use somthing like 'Squeak.exe my.image' squeak startups immediatly. I must always use '.bat' files for applications? Or exist way to do this with more style? Where is problem? I don't think it is so expensive for VM to find image file(s). Alex.

Re: self executable with squeak -- pause on startup

what I do is dragging an image on the squeak icon or shortcut... and it is fast ;)CÃdrick _______________________________________________ Beginners mailing list Beginners@xxxxxxxxxxxxxxxxxxxxxxxxxx http://lists.squeakfoundation.org/mailman/listinfo/beginners
