New Platforms and applications
by astares＠gmx.de 27 May '05

27 May '05

Hi, Found this today: http://weblogs.java.net/blog/invalidname/archive/2005/05/new_platforms_n_1.… Chris Adams is lamenting about Java, "Run everywhere" and new platforms and applications. Just wondering if Squeak is already ported to Microsoft XBox 360, Nintendo Revolution or Sony PlayStation 3? We dont have a Puzzle pirates game like Java - but a much cooler Squeak Pirates implementation (see http://www.impara.de/projekt_pirates.htm) But like Java Squeak is also still missing a collection of calendars, stickies, stock charts and other mini-apps ...

[ANN] wxSqueak 0.4
by Rob Gayvert 27 May '05

27 May '05

An update of my interface to wxWidgets is available at http://homepage.mac.com/rgayvert/wxsqueak.html Below are some notes on what has changed in this version. Any comments or suggestions are appreciated. .. Rob --------------------------------------------------------------------- 1. Uses the latest Squeak (3.8) and wxWidgets (2.6.0) releases. 2. Virtual method callbacks. It is now possible to create Squeak subclasses of wx classes such as wxGrid and wxListCtrl (and many others) that redefine parts of the default wx behavior. For example, renderers and editors written in Squeak can be assigned to cells of a wxGrid. About 90 methods for 18 classes have been added so far. 3. Client data may be added to items in list and tree controls. 4. More demos. Most of the wxPython demos that involve non-custom controls (around 75 or so) have been reproduced. 5. All ordinal arguments and return values have been converted to be 1-based instead of 0-based. This applies to list indexes, grid coordinates, pages in book controls, menu items, etc. 6. More assertions have been added to primitives. The short term goal is to intercept all of the assertions that may appear when using a debug build. Long term, the goal is to prevent any primitive from causing a crash because of bad arguments. 7. A VM linked with a debug build of wxWidgets is now provided. Using this avoids crashes caused by assertions in the wxWidget library code. 8. More support for XRC. Most components built with an XRC editor (e.g., DialogBlocks, wxDesigner, wxGlade, XRCed) can be instantiated now in wxSqueak. This will be the basis for a future GUI builder. 9. Monticello packaging. The Squeak source code is now organized into 5 Monticello packages. The Bootstrap package must be loaded first, followed by the WxWidgets package. The Tools, CodeGeneration, and Tests packages are all optional. Issues: 1. In wxMac, a few demos don't work, and there are display problems with some controls. wxMac is less mature than other platforms, but is catching up quickly. 2. Errors in virtual callbacks are sometimes fatal. 3. Memory leaks are less common, but still an issue. 4. Under Win32, the executable compiled with Visual C++ is only 50% as fast (as measured with tinyBenchmarks) Tentative Roadmap: 0.5 Unicode, Linux (GTK) version, custom controls, GCC build for Win32 0.6 API complete 0.7 Memory leaks fixed, more efficient event handling 0.8 GUI builder 0.9 Shrinking/modularization, app builder 1.0 Squeak 4.0

Yet Another SBC
by Frank Shearar 27 May '05

27 May '05

http://www.embeddedarm.com/epc/ts7200-spec-h.html >From the blurb: "TS-7200 Single Board Computer 200 MHz ARM processor for Linux * ARM9 processor with MMU * 32 MB SDRAM * 8 MB Flash drive (16 MB optional) * 10/100 Ethernet * Compact Flash * 2 USB host ports * 2 COM ports * 20 DIO * PC/104 expansion bus * Optional A/D and RS-485 * Optional 802.11b WiFi" What makes this interesting to be (with my Copious Free Time) is that the USB ports are HOST ports, unlike gunstix's CLIENT ports. The latter has always bugged me: I want an SBC to which I can plug in a NIC & a webcam and run a cheap SIP-based video source (aka "security camera", aka "baby monitor"). All on Squeak, of course! frank ******************************************************************* This email and attachments (if any) must be swept for viruses before opening.

Re: SqueakMap Release repository
by Chris Muller 26 May '05

26 May '05

Hi Lex, I just now noticed your reply, thanks. > Just by the way, did you remember to put in your repository password > before trying to save? > > If so, this still sounds like an HTTP problem, because of what shows up > at the top of the stack: Well, does the function work for you? Just to clarify, I'm speaking about adding a "SqueakMap Release" repository through Monticello's gui and specifying: MCSMReleaseRepository package: 'Tracing Messages Browser' user: 'cmm' password: 'my-Correct-Squeakmap-Password' However this gives me the stack-trace I pasted into my initial e-mail. After digging further, I noticed it was using the following method even after installing Monticello-231 in a stock 3.8-final-basic image. MCSMReleaseRepository>>squeakMapUrl ^ 'http://localhost:9070/sm' I do not have any localhost running on 9070 so this obviously isn't going to work. So I tried changing it to 'http://map1.squeakfoundation.org/sm' and then 'http://map1.squeakfoundation.org'. Both reported an error message but then, after looking on SqueakMap, it appears it did post something, albeit under just a partial name. i.e., the package I was trying to post was "Tracing Messages Browser" but it put it up there under "Tracing". - Chris

Problem with Process class using
by BELEM Mahamadou 26 May '05

26 May '05

Hello I have problem with the class process in SmallTalk. In my program I created many processes with a process by active object. After a time, I want that every object stop to run. For it, I use "terminate" methode but the objects continue to run. To stop the process I do: theObjects do: [: myObjet| myObject terminate]. in object class, I do : Object >> self proccess terminate. where process representes the object activity. Can someone say me where is the problem? regards --------------------------------- Découvrez le nouveau Yahoo! Mail : 1 Go d'espace de stockage pour vos mails, photos et vidéos ! Créez votre Yahoo!
