Re: A history of Squeak

I'm fascinated to see Squeak 1.1, but couldn't get it to launch in Windows 2000 using the VM in the WinVM.zip in there. I simply dragged Squeak1.1w.image onto Squeak.exe but the VM crashed instead of starting the image. See crash.dmp below. Of course, I also have Squeak1.1w.changes and SqueakV1.sources in the same directory. Am I doing something wrong? Oh.. Whoa, there it is! I tried using my 3.5 VM and it actually worked!

I've started the Server Image with: $ squeak ==> it works I start it with: $ squeak -headless ==> it doesn't work even after some minutes ... now the next strange behaviour ... I connect via RFB to the same headless image I started before which refuses connections. As soon as I connect to it, the Webserver accepts connections. This is exactly the moment after I typed the password to connect and accept it. Directly after the headless image accepts connections. I don't understand this behaviour. It is not so important to me to get this to work, but it would be good. thanks for any hint Chris Burkert PS: I'm using a fresh #5429 image with RFB and SmallWiki. PPS: RFB is a great tool. Thanks a lot for this Ian! -- http://www.chrisburkert.de/

[Unix] strange -headless behaviour with KomHttpServer
by Chris Burkert 05 May '04

05 May '04

Hi, I tried to run a Image with KomHttpServer and configured it to start up automatically when the Image starts. This works great when I type: $ squeak squeak.image It takes some seconds, the Server starts up and I can browse the content. But when I type: $ squeak -headless squeak.image nothing happens. I get Connection Refused every time and no SqueakDebug.log gets written. What can it be? bash-2.05b$ squeak -version 3.4-1 #1 XShm Wed May 5 15:07:17 CEST 2004 cc Squeak3.4 of 1 March 2003 [latest update: #5170] FreeBSD banias.csn.tu-chemnitz.de 5.2.1-RELEASE FreeBSD 5.2.1-RELEASE #1: Sat Apr 3 08:20:51 CEST 2004 chbu@banias.csn.tu-chemnitz.de:/usr/src/sys/i386/compile/BANIAS-5.2.1 i386 default plugin location: /usr/local/share/squeak/3.4-1/*.so I'm using 3.6 full #5429 images.

A history of Squeak
by Andreas Raab 05 May '04

05 May '04

Hi Guys, Recently I got interested in doing some statistics on the evolution of Squeak. As it turned out, trying to assemble the history of Squeak was quite a bit harder than I expected mostly because I didn't only want to cover the artifacts (images) but also the evolutionary steps (updates). Fortunately, with some help I was able to create what I think is a pretty complete history of Squeak from 1.1 to 3.6 (3.6 because it is the latest official release). However, because of the difficulties to assemble the history, I'd like to ask your help in preserving it. If you have some disk space (~100 MB) please consider mirroring http://isgwww.cs.uni-magdeburg.de/~raab/squeak/history so that these interesting bits and pieces don't get lost in the future. Also, just for the fun of it, I did some statistics on the author initials ever found in the update stream and assembled a little spreadsheet (in the "stats" directory) to see who has ever contributed to which Squeak version. It's pretty interesting to check this out and to see how much was changed in each version. If you are interested in similar historical aspects check out the little (rather ugly) stats.st script which does some analysis on the update stream. And if you find something interesting, let us know ;-) Cheers, - Andreas

Help: how to begin with Ballon3D?
by Joei 05 May '04

05 May '04

Hi! everybody I'm a C++ programmer and started to study squeak about four days ago. The implementation of squeak is so great that I felt it's really a pleasure to program with a pure object oriented programming language. Then I decided to port one of my C++ program which use OpenGL to squeak. I've read almost all documents in squeak.org and Swiki. I also read the book "Squeak: A Quick Trip to Objectland"written by Gene.Korienek. Then I decided to use Balloon3D to do my work. So I read the tutorial of Ballon3D come with Squeak. But I found out that I still cannot place a texture to a geometric object successfully. So, the question is: How to program with Balloon3D? or Where I can find more documents about it. Many thanks Jo.

Magma is pretty close to that - though I >> am not sure how intrusive it is in the image. I can comment on this. First, as far as intrusiveness goes, it is very *non-intrusive*. That was a primary design goal from the very beginning. There are *no* base changes, even though there are several method *extensions* to base classes. But all my extension methods are prefixed with "ma" to minimize namespace collisions. Let me tell you, when you load Magma into your image, you can feel confident that your image will remain perfectly intact.

Yeah, the reason the Magma SAR is 185K is because Magma is composed of about 10 independent "modules". This does tend to add to the bulk of the code. The other consideration, though, is the size of the *allocated-memory* footprint while running. As far as Magma goes, I decided to make the server as "lightweight" as possible in terms of allocated-memory footprint so as to support as many simultaneous users as possible with a reasonable machine. Almost *nothing* is cached and no domain classes are necessary on the server. The server only deals with "buffers" for the current request and the Integer oid relationships between them, which will also hopefully facilitate optimization via primitivization (say that 5 times) of certain behaviors on the server. In terms of the client, Magma is only as light as the client program allows. WeakDictionary's are used to let unreferenced objects out, as well as things like ReadStrategy's to optimize bringing only the objects you want into the client. #stubOut: is also available to chop off large branches of objects after you've already read them in but no longer need them. I am very excited about Magma's future. The latest version on SM is the best-yet, and I'm currently working on some exciting enhancements (exciting to me, anyway) while still keeping with its philosophy of simplicity. - Chris
