Project Loading 3.9, 3.10
by Derek O'Connell 03 Apr '08

03 Apr '08

I cannot reload a saved project back into the same 3.9 image or into the latest 3.10 (both "dev" images). It seems "RenamedClassSourceReader" is not implemented. This is documented as a 'new' and 'major' bug in mantis from 01-11-07 (http://bugs.squeak.org/view.php?id=5720). Any work-around?

Hackontest Announcement: Form a team, implement sth. useful and win a trip to Zurich
by Markus Gälli 03 Apr '08

03 Apr '08

Hi folks I've just added Squeak to the "Hackontest" open source gathering- competing-whatever-event which should happen in Zurich this September. Bottom line: Come to Switzerland this summer and get your trip paid from this well know advertisement company by adding some cool feature to anything Squeak.

I did this in Squeak1.1.image (this was the baseline of my benchmark comparison) so it should work fine with 2.3. Cheers, - Andreas

Just increment the numbers in #tinyBenchmarks (incrementing by one roughly duplicates the run time, so incrementing by 4 should be more than enough). Paolo

The Old Man
by Marcus Denker 01 Apr '08

01 Apr '08

"One of the sad memories of my life is a visit to the celebrated mathematician and inventor, Mr Babbage. He was far advanced in age, but his mind was still as vigorous as ever. He took me through his work-rooms. In the first room I saw parts of the original Calculating Machine, which had been shown in an incomplete state many years before and had even been put to some use. I asked him about its present form. 'I have not finished it because in working at it I came on the idea of my Analytical Machine, which would do all that it was capable of doing and much more. Indeed, the idea was so much simpler that it would have taken more work to complete the Calculating Machine than to design and construct the other in its entirety, so I turned my attention to the Analytical Machine.'" "After a few minutes' talk, we went into the next work-room, where he showed and explained to me the working of the elements of the Analytical Machine. I asked if I could see it. 'I have never completed it,' he said, 'because I hit upon an idea of doing the same thing by a different and far more effective method, and this rendered it useless to proceed on the old lines.' Then we went into the third room. There lay scattered bits of mechanism, but I saw no trace of any working machine. Very cautiously I approached the subject, and received the dreaded answer, 'It is not constructed yet, but I am working on it, and it will take less time to construct it altogether than it would have token to complete the Analytical Machine from the stage in which I left it.' I took leave of the old man with a heavy heart." -- Lord Moulton -- Marcus Denker -- denker(a)iam.unibe.ch http://www.iam.unibe.ch/~denker

Re: Problems installing FFI on 3.10 release
by astares＠gmx.de 01 Apr '08

01 Apr '08

Hi Andreas, the problem comes from Monticello 1.5 which is AFAIK now used in squeak-dev image. (Note that the squeak-dev image from Damien for 3.10 is still beta!). So let's try the real 3.10 without anything loaded. The offical release 3.10 image is http://ftp.squeak.org/3.10/Squeak3.10.gamma.7159.zip When I use this clean image and open Universe Browser, select "update list from network", then load System ->FFI Version 3.9.1 -> IT WORKS AND LOADS FINE (but still has the NetNameResolver problem (Mantis 6980) we discussed in March and which requires your patch for the image before loading FFI) Using Monticello 1.5 in Sq 3.10 is currently problematic. For instance it makes an ugly overrides for HTTPSocket>>httpPut:to:user:passwd: where HTTPProxyServer class variable is used directly instead of using "self httpProxyServer". This was OK for pre 3.10 but now things have changed. Bye Torsten -- Ist Ihr Browser Vista-kompatibel? Jetzt die neuesten Browser-Versionen downloaden: http://www.gmx.net/de/go/browser
