Re: [Pharo-project] [squeak-dev] Play MP3s in-image

by John M McIntosh

Actually this is the old ancient first cut at an MP3 player that was written by John Maloney in 2000. It's pre-sophie and I'm not sure of the licensing as it might have been purged from the image and replaced by other code in the last 10 years from contributions by the eToys work, and yet another player I wrote. The *real* Sophie player starts with the SophieMovie abstract class. On 2010-12-13, at 8:52 AM, DeNigris Sean wrote: > I extracted the mp3 support from Sophie.

Igor, Thanks for your initiative, and I expect a lively discussion moving forward ;) To the community at large, We have a wonderful mix of people participating in Squeak/Etoys/Phoro/Cuis and other projects, some of whom have be participating for many years, as well as many newer contributors. Regardless of how the VM(s) are managed in the future, I would ask that everyone with an interest in this please be respectful of the people who created the original work for our benefit. In particular, Andreas, Ian, John, and Eliot have contributed major VM development that they have made available to us with open source licenses, and Dan Ingalls' original portable VM is a remarkable piece of work from which we all are benefiting every day. So the meta-comment is: Let's all be respectful of the wishes of the original authors of these works. For those doing VM platform work, I would ask also that you take the time to read the various README and documention files to be found in the platforms sources, as these often contain guidance as to how the code should be managed, how contributions can most effectively be made to the original authors, and of course how to build the VM for each respective platform. Thanks everybody! Dave

[Pharo-project] trying to load seaside from scratch into Pharo 1.1 or 1.1.1

by Lawson English

I get a pristine one-click image for 1.1 or 1.1.1 from the pharo-project website and do: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSeaside'; load. ConfigurationOfSeaside load. an hour or so into the install, I get message: Error: stream is already in a subclass of WAHtmlDocument. This is using Mac OS X SnowLeopard. :-( Lawson

The other Damien used that for the "by example" books. It works well to import the whole history, and I think for tracking authorship it would be a good idea. However, it would probably become an organization nightmare if people commit to both svn and git. Someone has to keep a git-svn clone somewhere and periodically update from svn and push/merge to git. Of course, unless there is a branch under git just for that, as soon as there is a merge conflict, human intervention will be needed. Also, that git-svn clone must not be lost. I'm not sure you can re-build it and the checksums will still match those on the git side. -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet

If you (or anyone else) want to help with that, just register, and i will simply add you to squeak-vm-developers group, so you can copy the whole history.

I think being able to preserve the history would be considered a pretty big plus if switching :) Cheers, Henry

I prefer being focused on hacking the code rather than reading boring docs/help about VCS tools. :) What is good in web-front end sites like gitorious, that you can do most of boring administration tasks using nice web UI.

I've been able to reproduce a crash on Windows in 1.0, 1.1, 1.2 beta and Squeak 4.1 images (release and trunk) using the Squeak 4.1.1 VM. My provocative test was (seemed to happen less often with large (>3MB) images): FileStream oldFileNamed: 'trouble.jpg' do: [:img | imageStream := RWBinaryOrTextStream with: img binary contents]. 50 timesRepeat: [[ ImageReadWriter formFromStream: imageStream] forkAt: Processor userBackgroundPriority ]. Just executing the code in the forked block works just fine. Cheers, Henry

Thanks Igor.
