Re: Yahoo archive truncated

Hi Scott, A warning message (from Yahoo!) has just shown up on my screen. It says "Warning! Your group has exceeded its message storage limits of 64 MB by 0.0 MB. If you don't remove messages, older messages will be deleted to make room for new ones.". It might be the reason. I first noticed that last week when I saw "Using 64.0 of 64 MB (100%)" on the top right/bottom right of the group's messages page at <http://groups.yahoo.com/group/squeak/messages>. It is funny you can still see that warning there...

[Fix] for Events-3.2 and Zurgle
by Jeff Sparkes 26 Sep '02

26 Sep '02

I've been running with Zurgle, and then filed in Events-3.2.cs from Ned Konz to switch to the newer event model, and I couldn't pop up the Zurgle preferences. As far as I can tell, Morph>>updateableActionMap was not returning the new ActionMap. It seems that setProperty should return the property value, but I couldn't figure out why it wasn't. The fix just assigns to ActionMap to a temp variable, then returns it. There may be a better way, but this gets me my preference dialog back.

An example...
by Stephan B. Wessels 26 Sep '02

26 Sep '02

Couple weekends ago I installed Squeak 3.2 on a Linux box and started tinkering with some simple enhancements to FileList to help me move change sets over from my Macintosh. I wanted to ³stay inside Squeak². After going through the steps of writing some simple, but useful code, I realized there may be Squeak developers out there who would benefit from the ³process² I used. Calling it a process may be generous. So the following weekend I tossed the code out and began again but this time wrote an HTML based document, with lots of pictures, to describe what I did. The idea being it might help someone. The alternative may be unforgivable. :) Given all that, you are welcome to look over http://w3.one.net/~swessels/pages/steve/squeak/copyFilesTutorial/index.html Constructive feedback is welcome. - Steve

[FIX] RandomFix-sr v2
by Stephan Rudlof 26 Sep '02

26 Sep '02

I have forgotten a small fix in Random in the last version. Greetings, Stephan "Change Set: RandomFix-sr v2 Date: 26 September 2002 Author: Stephan Rudlof Random: - corrected: >>seed: needs to call initialize just once. >From the class comment of BRandom: BRandom: - simplified Random with corrected comments. - faster as the original (more than 25%). - no changed semantics (should give exactly the same results as Random (except for the errorneous seed 0)). - could replace Random (by merging the methods and removing obsolete inst vars in Random). Since Squeak Floats are working with 53 bits for the mantissa, Random nextValue has been simplified (see BRandom nextValue). Precision is sufficient... (16r7FFFFFFF * 16r000041A7) asFloat asInteger = (16r7FFFFFFF * 16r000041A7) ...since Float works with 53 bits and we need less than 48 (46 without sign bit): (16r7FFFFFFF * 16r000041A7) hex '16r20D37FFFBE59' . The comments are corrected regarding the border cases (min and max values). Test: | bc rand irand | bc _ [:r :num | num timesRepeat: [r next]. ]. rand _ Random new. irand _ BRandom seed: rand seed. { { [bc value: rand value: 100000] timeToRun.

squeak in a german version
by Utta C. Hoffmann 26 Sep '02

26 Sep '02

dear specials and anyones of the squeakfondation, i got your e.mail from allen russell - i was looking and am looking for a german squeak -version, that i can use in schools( i'm teacher in arts und would like to introduce kides in a crreative manner of computer handling. so it would be nice, if i can get a hint from you! thank you a lot and in hope of a sign utta Guten Tag Utta! Es tut mir leid, aber mein Deutsche ist nicht so gut, also ist dieses email auf english :) The menus, code and general interface to Squeak are only available in English. However the eToys component of Squeak (which is especially designed for children) has been translated into a number of languages. I don't know whether German is one of those languages, but there are several German users of Squeak. I suggest that you subscribe to the Squeak email list and ask your question there; I'm sure many people will be happy to talk to you.

Crash Dump from 3D morph

SqueakMap 5:th release!
by Göran Hultgren 24 Sep '02

24 Sep '02

Hi all! Just released SqueakMap with some nice/cool additions: http://anakin.bluefish.se:8000/gohu/11 Don't miss the additional fix I threw up there too. Daniel - I have not integrated you Loader yet - but this release should be interesting for you (a number of the things we have been talking about are now reality). I haven't updated the entry in SqueakMap itself yet though because this release contains some fairly new code that I haven't had time to bang my keyboard on. :-) Features to notice: - New installer architecture to be able to deal with different "package" types more easily. Anyone wants to add an Installer class for 3.3a Modules? Or for Projects? (.pr-files) Or some nifty other source formats like SIF? - The client now sends "SMSqueakMap version" in the update requests and the server can then "refuse" to serve a client with a too small version number. This was added to help us later when we have a lot of users of SqueakMap and we need to evolve it. We will only raise this version number when the SqueakMap code changes so much that the client needs to be updated. - Now SMSqueakMapBrowser only has buttons for "download" and "install". The former always tries to unpack. Any old files are now overwritten. The menu choices and the buttons are now sensitive to whether the package actually can be downloaded and/or installed. - A new button has appeared in SMSqueakMapBrowser called "fast install package". It has a menu (ripped off) similar to the "new morph..." menu. You simply select the package you want and bam, there you go! Can't get any faster than that! (need to add some "Cursor sleep" stuff there...) - SqueakMap now remembers (but only in RAM, not in the logfile - but it does actually log it in the ChangeSet so that it stands a fair chance to remain "correct" in case of an image recovery operation) what packages you have installed and their version names! This means it can present them in a menu and also show which packages are "upgradeable" (=new version available according to SqueakMap). Do note though that simply filing in again might not be a good upgrade method! But it does offer you to enter a new name for the changeset in order to avoid clashing with the old one etc. Some way to clear out the information on what packages are installed (if it gets corrupted) would be nice to add too. This "fast install package"-menu is my "take" on the minimal UI for SqueakMap that we are thinking of putting into the regular 3.2 update stream - just the menu. The menu would typically be available somewhere in Squeak and the map would automatically do a "load updates" before it pops up (in the browser you need to press that button manually first). Currently it shows installable packages (packages that some installer says it can install), installed packages and upgradeable packages. Any choice tries to install the latest version of that package - even if it is already installed. Rather neat. The label between parentheses shows installed and/or available version. Now I am off to Greece! Will be back on monday. regards, Göran PS. Personally I think I would vote for this alphabetic menu to be the "base minimal UI" in 3.2 and the next level would be Daniels Loader (which is a simplified SMSqueakMapBrowser) and then if you really want to get confused you install SMSqueakMapBrowser. The last two should of course simply be installable packages using the alphabetic manu.

You aren't given that choice. Maybe not, but when you load the project, it _is_ copied into your squeaklets directory and can be loaded from there as often as you like. Cheers, Bob
