Re: Re: [Q] WAListener and WAFileLibrary problem
by chunsj＠embian.com 03 Jan '08

03 Jan '08

For me, all the encoding related part does work well. My problem is that - as I said in my previous mail - now binary image file registered at WAFileLibrary, could not be sent correctly. During reading your message I found one possibility that can corrupt image file. I'll investigate that part. Thank you. PS) My application does use UTF-8 for both input/output. ----- Original Message ----- From: Niko Schwarz <niko.schwarz(a)googlemail.com> To: chunsj(a)embian.com, The general-purpose Squeak developers list <squeak-dev(a)lists.squeakfoundation.org> Sent: 08-01-03 23:46:37 Subject: Re: [Q] WAListener and WAFileLibrary problem <div>It appears that you're trying to convince Seaside to send UTF-8, right? I had the same problem during my time working with it. Then again, I didn't want complete texts but only the Euro currency sign.

News Report Dec 2007
by Ron Teitelbaum 03 Jan '08

03 Jan '08

Happy New Year everyone, Here is your news report for Dec 2007 and the year. We had a big hit with Craig's pictures http://news.squeak.org/2007/12/29/old-smalltalk-pics-from-parc-place/. There was an amazing amount of interest: 29,614 hits! Thank you! Craig helped us to beat our record and gave us our best day ever of 17,959 hits on Dec 30 (this was more then all the hits we received last month). This was a very nice way to end the year. Our second place post was http://news.squeak.org/2007/12/05/demand-olpc/ with: 1279 hits. We had only 5 posts for the month. Our search hits continue to be very strong on search keys that include 'OLPC'. For the entire year of 2007 we had 179,745 hits. This was our first full year (total of 16 months). My impressions of the Weekly Squeak are that we are doing quite well. I've noticed that there is a lot of talk about Smalltalk and Squeak and we are receiving a number of links from other communities, blogs and web sites. I'm sure most of the buzz has been generated by OLPC, Croquet and Seaside but I would like to believe that we helped a little to raise the awareness of other developers about the Squeak community and our continued support and progress. We have a terrific community and I'm looking forward to the new year of Squeak and Smalltalk. We are proud to be a part of and support this community. Thank you for supporting and reading the Weekly Squeak! Ron Teitelbaum and The Squeak News Team

Re: Squeak on a flash drive

Flash drives are plenty big nowadays to carry any and all smalltalks out there at the same time, no? Why would you care how big the image actually is?

my Framework
by David Zmick 03 Jan '08

03 Jan '08

i am working on a program with a framework, and modules that will plug into it, and i need to know how to send a class name around. for example: i have a method in one class, that servers as a module, that will "Procces Commands" sent to the framework. I have another class that is suposed to manage the commands and getting them to the right place. ManCommands-the command managing class Framework-the framework that manages input/output BasicModule1-a module that will eventually be used to run other "modules" how do i get the framework to tell ManCommands to send the command sent to the framework to the ProccessCommand method it BasicModule1>

IPC with Squeak
by Michael Haupt 03 Jan '08

03 Jan '08

Dear all, here's a little scenario for which I can imagine an implementation that I don't like, though. A process is talking to a running Squeak VM/image, sending it requests. Squeak responds. Through what channels could both requests and responses be sent? I can imagine using networking (sockets), but since the process and Squeak VM will surely be running on the same machine, that seems a little bit exaggerated. Are there other ways of doing IPC with Squeak that exist in the form of a loadable package? (Or would they have to be implemented?) Best, Michael

Close to/After the beginning of 2008 it might be a good time for an (ugly) but fun hack! ;) The project can be loaded into a 3.9 image. http://www.lazarevic.de/download/squeak/fireworks.002.pr This should also work, but no guaranties... http://squeakland.org/project.jsp?http://www.lazarevic.de/download/squeak/f… Cheers (in every sense), Alex :D PS: This is the result of some fun hours of hacking, but shouldn't be looked at closely! After all this should be much nicer in kedama! PPS: Use Alt-. to stop it

VM crash in primitive 230. PLEASE HELP
by Trygve Reenskaug 02 Jan '08

02 Jan '08

How does primitive 230 work? It crashes on my PC for certain operations, never on my laptop). There must be something wrong in my WinXP, but where? The primitive method is Socket>>primSocket: socketID sendData: aStringOrByteArray startIndex: startIndex count: count <primitive: 'primitiveSocketSendDataBufCount' module: 'SocketPlugin'> self primitiveFailed In the hope of enlightenment, --Trygve ================================================= Details: WinXP SP version 5.1 (SP2) Squeak 3.10.6 (release) from Aug 30 2007. Compiler: gcc 2.95.2.1999 1024 (release) Image: Squeak3.10.gamma.7159 out of the box (Same problem with earlier versions of Squeak) I have trouble with Universes and MC when accessing over the net. Some operations work OK, other operation cause a crash with byte code 224, primitive index 230. I have traced the problem from the Squeak end, and added a halt in Socket>>sendSomeData:startIndex:count: I have done two experiments, both of them consistently reproducible: EXPERIMENT 1 is the command: <UniverseEditor::update package list>. This command always works OK.

Pre-Release of the Scratch Source Code
by Jens Moenig 02 Jan '08

02 Jan '08

Dear Squeakers, Just to let you know that MIT has pre-released the Squeak source code of Scratch. Check out John Maloney's announcement in the official Scratch forum: http://scratch.mit.edu/forums/viewtopic.php?id=2745 The release mainly consists of a slightly modified developer's image and a changes file all based on a trimmed down and streamlined 2.8 (!) version of Squeak. Another interesting feature this dev-image contains is a built-in one-click deployment script to be found in a special developer's menu. In any way it's great fun to play with, and a source of inspiration to me, on how to create a great Smalltalk application out of a rather small base image. To fully use the non-Scratch parts of this dev image you should also get an old v2 sources file. - Jens - -- View this message in context: http://www.nabble.com/Pre-Release-of-the-Scratch-Source-Code-tp14577145p145… Sent from the Squeak - Dev mailing list archive at Nabble.com.

etoys tutorial

etoys tutorial Hi Kemal, Seems to me you had a perfectly good expectation of what to find in a "make your own etoy project". And its good feedback to let people know how what it is differs from the expectation. A very good and interesting way to learn about making etoys is to watch the 20 episodes of Squeaky tales at: http://www.waveplace.com/movies/ Their creator, Timothy Falconer ( http://bigfractaltangle.com/aboutMe.jsp ) , has promised more episodes in the near future.
