by Igor Stasenko 25 Sep '09

25 Sep '09

Here the changeset which allows loading the packages with classes having nil superclass in MC. I'm not sure who is in change with MC, so i cross-posted it to dev list(s). -- Best regards, Igor Stasenko AKA sig.

Nicolas Cellier uploaded a new version of Morphic to project The Trunk: http://source.squeak.org/trunk/Morphic-nice.191.mcz ==================== Summary ==================== Name: Morphic-nice.191 Author: nice Time: 25 September 2009, 7:41:07 am UUID: adaf0573-f44a-0340-9626-2b9f99d02c32 Ancestors: Morphic-ar.190 Fix for http://bugs.squeak.org/view.php?id=1035 Changing the extent of a PolygonMorph does also change its origin... This was not expected by some container Morph: when container were resized, the PolygonMorph contents was moved weirdly, sometimes outside the container.... For fun, this did happen only when growing the container size, but not when shrinking... See super bounds: and order of message send #extent:/#position: or #position:/#extent: to understand the bug... The solution I adopted is to always use the extent:/position: order in the PolygonMorph. =============== Diff against Morphic-ar.190 =============== Item was added: + ----- Method: PolygonMorph>>bounds: (in category 'geometry') ----- + bounds: newBounds + "This method has to be reimplemented since self extent: will also change self bounds origin, + super bounds would leave me in wrong position when container is growing. + Always change extent first then position" + + self extent: newBounds extent; position: newBounds topLeft + !

breakpoint at primitiveAdd
by Ang Beepeng 25 Sep '09

25 Sep '09

Hi all. I run Squeak in debug mode. I put a breakpoint at function 'primitiveAdd'. By right when I print '3+4' in a workspace, Squeak will break. But, strangely, nothing happen, and the result returned. When I debug '3+4', the breakpoint triggered. What is the problem? Thanks a lot.

Built 64 bit vm for 64 bit compaq ES40 alpha server running gentoo linux.
by richard snow 25 Sep '09

25 Sep '09

I was able to use vmmaker to generate a 64 bit vm for the Alpha. However it can't run 32 bit images, so I'm kind of stuck. Where could I get an image (3.10-6 hopefully). Richard Snow -- http://mypals.info

Not sure where to post this
by Chris Hogan 25 Sep '09

25 Sep '09

Has anyone else noticed this? http://gizmodo.com/5365299 Does anyone know if Chuck Thacker had anything to do with this project? It seems very dynabook like, and it almost looks like it has some sort of Google Wave type functionality from the video release. If this thing is anywhere near as cool as the video, it's the notebook I have been dreaming about. -- View this message in context: http://www.nabble.com/Not-sure-where-to-post-this-tp25614041p25614041.html Sent from the Squeak - Dev mailing list archive at Nabble.com.

Recent MC doesn't support loading classes with nil superclass?
by Igor Stasenko 25 Sep '09

25 Sep '09

Tested both in Pharo-Core & Squeak trunk image. The class i defined is: ProtoObject subclass: #BBBNameOfSubclass instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'NILSuperClass'. BBBNameOfSubclass superclass: nil In attachment you can fin the fileout of it. And MC package, saved with it. If you try load the package, MC will display warning that you should resolve dependencies 'nil' before loading the class ;) Background: I wanted to migrate to newer image and saved my package, im working on, which i didn't touched for 3-4 months, and found that it can't be loaded :( -- Best regards, Igor Stasenko AKA sig.

minExtent vs. minHeight/minWidth
by Markus Lampert 25 Sep '09

25 Sep '09

Hi all, I'm looking into fixing the ProportionalSplitterMorph behaviour in SystemWindow and came across minHeight and minWidth, which return unrelated results to minExtent (quite to my surprise). minHeight/minWidth almost always return 2 unless specifically set otherwise, via minHeight:/minWidth:. minExtent actually tries to come up with a reasonable minimum extent for the receiver. Given the naming I would have expected minHeight/minWidth to be implemented in terms of minExtent, or vice versa. Does somebody know what the intent of the 2 different interfaces is (the method comments don't help)? Thanks, Markus

Test mp4-movies from ESUG, feedback wanted...
by Göran Krampe 25 Sep '09

25 Sep '09

Hey! Two testmovies from ESUG: http://mimer.msc.se/esug In short these movies are x264 encoded, mp4 container using 720x576 (original resolution) with some deinterlace/denoise tricks, variable framerate (same as source), bitrate 1500kbps, two pass encoding, AAC sound mixed down to mono and resampled to 22.05khz, bitrate 32kbps. Phew! How did I create them? I ended up using Handbreak, first playing with its excellent UI and then ending up scripting it from the CLI. It seems the two leading "transcoders" in Linux land are Avidemux and Handbreak. I just happened to use Handbreak. This is the script for anyone interested: #!/bin/bash HandBrakeCLI -i $1.$2 -o $1.mp4 --preset="Normal" -m -I -b 1500 -2 -T -e x264 -x ref=2:bframes=2:me=umh -E faac -B 32 -R 22.05 --mixdown mono -d fast --denoise medium And you use it like: "./hb INPUTFILE MP2" ...which should spit out: INPUTFILE.mp4 Regarding all the options above, see this page: http://trac.handbrake.fr/wiki/CLIGuide I have not yet started to "batch through" all the files so you typically have until tomorrow to give me feedback on different options and/or tell me that the DAMN files don't work! :) regards, Göran PS. Later when I put them all up we can "decipher" them together and write some description on what is on them :)

Hints on encoding ESUG movies using mencoder...
by Göran Krampe 24 Sep '09

24 Sep '09

Hi! I have a bunch of mpeg2 movies that I got from Jorge at ESUG. I looked around a bit on "current approach" to encoding and I came up with vanilla mencoder using lavc like this: mencoder M2U00051.MPG -o esug1.avi -ovc lavc -oac lavc -ffourcc DX50 This will produce an mp4 movie with mp2 sound tagged as "Divx5" in order to make it work in most players. Anyone have other options I should use? Otherwise I will encode these and put them online as soon as I can. regards, Göran
