Time seconds in 3.10
by Jimmie Houchin 08 Dec '07

08 Dec '07

Before Squeak 3.10 Time now seconds. returned a SmallInteger. Now it returns a Fraction. This was discovered in Seaside when I was using 3.10 and encountered a DNU. I fixed what I thought was a bug in Seaside only to find it is the Squeak behavior that changed. But I am having difficulty finding the code that returns the Fraction in 3.10. Just trying to learn the behavior and difference between 3.10 and before. Philippe on the Seaside suggested this _might_ be a bug 3.10. Why the change and is this a bug? And any help showing me where the Fraction enters the picture, greatly appreciated. :) Thoughts. Thanks. Jimmie

Success flag and using return value of primitive function
by Igor Stasenko 08 Dec '07

08 Dec '07

Currently, a VM expects nothing in return from primitive function (actually functions have format sqInt (*)(void) but result is not used). I'm wondering, why in VM , to indicate success, a successFlag global variable used instead of just returning 0 or 1 to indicate if call was successfull or not? To what i see, if not using the successFlag , then speed can be improved, because there will be less frequent reads and writes to successFlag by simply reusing a return value from function which is currently ignored. The good point in using a successFlag is, that it can be set anywhere in primitive and then do something else, and only then return from function. But a common scenarion is often look like: something isWrong: [ ^ interpreterProxy primitiveFail ] where primitiveFail internally sets successFlag to false. So, can anyone provide arguments, why its done in such way? -- Best regards, Igor Stasenko AKA sig.

I have installed RB and AST from SqueakMap for 3.9, but I have many random problem swith features not working as hierarchy browsing, simple editing in the browser, refactoring tools as renaming methods. These problems happen more or less randomly. Hilaire

ANN: new Genie release
by Simon Michael 07 Dec '07

07 Dec '07

As penance, and encouraged by Brian, I ended up doing a bunch of work on the Genie package yesterday. Genie is a very cool gesture recognition system by Nathanael Schärli that for years required a bit of setup work and has been largely ignored. I'm pleased to announce that there is now a ready-to-run version of Genie on squeak source. This version includes better Squeak integration, a small dictionary of useful gestures for project navigation and UI control, and most of all, should "just work" after installation. It has been tested with Squeak 3.10 and 3.9 so far. Please give it a try and ask questions if you have any trouble. http://squeaksource.com/genie.html Also note the squeaksource Genie project is now globally-writable, so feel free to make it better. Thanks - Simon

Hi, > I'm happy to see that our book has been donwloaded 11708 times so far. > The french version is around 70% and apparently some people started a > translation in spanish. Excellent! Does anybody know who is in charge of the spanish translation? I'd like to join. > So you can do three things: > - buy the book :). The quality of the printed version is quite good. > - write new chapters (more costly) for the next volume > - translate it to new languages. May I suggest you to consider the translation and incorporation to SBE of some chapters from the french book "Squeak, programmation" by Xavier Briffault? (with his permission, of course!). I'd suggest (some version of) chapters 7 ("Le noyau systeme de Squeak"), 8 ("Notions avancees: application de la reflexivite en Squeak") and 9 ("Les processus"). Of course these chapters should be conveniently adapted to the overall philosophy of SBE. I'd volunteer to do it myself, but my knowledge of the french language barely allows me to read some technical books. Anyway, I liked Briffault's book a lot and I think that those chapters would add nicely to SBE. Besides, there is no english translation of the above mentioned book, so a partial translation would make available some of Briffault's work to english readers.

An idea about the license problem
by Chris Cunnington 07 Dec '07

07 Dec '07

How about "The Add A Comment Campaign"? Finding people is hard, and dealing with them is worse. So forget the people who wrote the code. They don't matter. What we need is a list of the pieces of code that need to be accounted for. With that list we can address the problem. All those pieces of code need to be modified, and new initials left to cover over the older author. The easiest modification (thank you Ron T. for your expressing your trepidation about modifying the code) is to leave a comment. In the code. With quotation marks. Thus all the pieces of rouge-owned code get modified by people we can get to sign the form. Voila. Give me a list of all the pieces in Squeak, and I'll assign them to volunteers willing to leave ten comments apiece. If their are five hundred pieces that need to be changed that's fifty volunteers. And if you think this is a facile solution, then I request you define the word "rewrite" and ask who's going to adjudicate the level of "rewritedness"? At the very least create a list of code that needs to be re-owned and forget the list of people who wrote it. They're long gone, man. Chris
