[ANN] Beta version of Squeak 3.7 CDROM
by Marcus Denker 05 Nov '04

05 Nov '04

Hi, Under ftp://ftp.ira.uka.de/pub/squeak/cdrom/ there is now Squeak 3.7 as a CD image. The CD has -> Squeak 3.7 dir from ftp -> latest SqueakLand installers -> Smaltalk Books from ESUG CD -> Croquet installers -> SqueakMap Mirror. There's no space for the rest that used to be on the CD (Mailinglist archive, swiki archive...), but these will be on a Squeak DVD (later this month, I guess). This CD will be available via swiftCD after a week or two of beta. I would be nice if some windows user could run a virus-checker over the contents of the CD. Marcus

"Create, Play ad Learn" grant
by Roel Wuyts 05 Nov '04

05 Nov '04

Hello, somebody from Microsoft forwarded me this link. It immediately struck some chord: looks like an excellent way to get money to (re)develop (part of) etoys or Croquet (or some extention to it, etc.). The really nice thing is: there is no need to use Microsoft-specific technology, like they ask in some of their other research proposals or contests. And with only 6 pages the proposal is not to heavy. Deadline is end of November. Smells like a real opportunity... > Call for Proposal on “Create, Play and Learn – Innovative > technologies with social and cultural value” > > > > Microsoft Research Cambridge (MSRC) is pleased to announce the > ‘Create, play and learn’ call for proposals (CFP) to solicit, support > and generate new ideas and technology applications with leading > researchers in partnership with MSRC.

I2C Serial Port in Squeak
by Jon Hylands 05 Nov '04

05 Nov '04

Hi everyone, I have a question for the VM guys -- I'm planning on using an I2C bus on my next autonomous robot, and the Squeak machine I'm going to use (www.gumstix.com) has a hardware I2C interface, with a driver for it in Linux. As far as I can tell, the I2C port looks just like another device in Linux, so I'm hoping I can just use the serial port with a different com port #. Any thoughts? Later, Jon -------------------------------------------------------------- Jon Hylands Jon(a)huv.com http://www.huv.com/jon Project: Micro Seeker (Micro Autonomous Underwater Vehicle) http://www.huv.com

[Q] Package dependencies
by Chris Muller 05 Nov '04

05 Nov '04

I am at a crossroads trying to determine whether I should keep bothering with package-dependencies. Monticello supports dependencies by using "add required package" on the menu. But I have run into an unexpected, but understandable behavior. To describe, consider my package hierarchy: MagmaServer.23 requires MagmaClient.24 requires Ma Client Server.17 requires Ma Object Serialization.21 Now I do some work on MagmaServer and Ma Object Serialization, and now have MagmaServer.24 and Ma Object Serialization.26. Note that Ma Client Server did NOT change, it is still at version 17. Now I Save MagmaServer.24. Even though expanding the hierarchy in the Monticello browser shows the most-recent, working-copy versions of all my packages as the dependencies, Ma Client Server.17 is still referencing Ma Object Serialization.21 instead of 26. I understand that Ma Client Server references its exact dependency versions by UUID and, since it didn't change, didn't resave it just because one of its dependencies evolved. Still, its confusing that the UI shows the version of the current working copy when you expand the dependency tree, not the exact dependency version. Also, when I save a package that defines dependencies, Monticello automatically saves versions of all *changed* dependencies; implying that the root-package you are saving is being saved with its dependencies as a whole. But wait, those packages that didn't change are still pointing to older versions of their dependent packages. I expect this is also why, after copying all my latest .mcz files into a SAR that I sometimes still get "not found" errors when trying to load on another computer; the referenced dependency is an old one and I only have the newest ones in the SAR. This is painful, so I'm thinking of just ditching dependencies and loading packages and building SAR's manually.. unless there are other alternatives I'm not considering.. Doesn't everyone have these challenges? What is a best-practice? Thanks, Chris

TestRunner in 3.8 -- ARGH!!!
by Torsten Bergmann 05 Nov '04

05 Nov '04

Hi, after the heavy discussion on the list I refactored TestBrowser again, commented it, repackaged it as Monticello package and registered it as a project on SqueakSource. I added some people as developers. As soon as Kazuki Minamitani-san has registered on SqueakSource.com I will add him as a second Administrator and developer. Anybody who would like to add more features to it or restructure it to use OmniBrowser as a base is invited to help. Try downloading http://www.squeaksource.com/TestBrowser/TestBrowser-tbn.115.mcz Note that it installs a preference #testBrowserRunsAbstractClasses - so it's up to the user how it should behave regarding abstract classes. More infos: http://minnow.cc.gatech.edu/squeak/3891 Andreas wrote: >I tried it and I couldn't get it to show my test category unless I >switched >to "show all" (this might be a bug in the filtering). is this still a problem, if so please send a changeset to reproduce it.

Make morph stay in front
by Trygve Reenskaug 05 Nov '04

05 Nov '04

Hi, I have a subclass of PasteUpMorph called DialogMorph. The only thing special about it is this method: morphicLayerNumber " Should make dialog stay in front (most of the time), but DOESN'T " ^3 But it doesn't stay in front. I can clock any window and it pops in front of myDialog. Anybody have any ideas? I'm running Squeak 3.7-5989-basic under WinXP (Same problem in Squeak3.6-5429-full) Thanks --Trygve -- Trygve Reenskaug mailto: trygver <at> ifi.uio.no Morgedalsvn. 5A http://heim.ifi.uio.no/~trygver N-0378 Oslo Tel: (+47) 22 49 57 27 Norway
