I've also update the Linux and Mac VM to the latest version in the one-click distribution of 3.0. If there are no complains, we can use that container for Seaside 2.8.x too :-) Lukas On 9 February 2010 00:07, John McKeon <p3anoman(a)gmail.com> wrote: > Fixed > Seaside 3.0a5 > Pharo1.0rc1 update 10505 > > On Mon, Feb 8, 2010 at 5:50 PM, Lukas Renggli <renggli(a)gmail.com> wrote: >> >> Thanks for all the help, I've uploaded a new version of the Seaside >> One-Click distribution with the adapted ini file.

It seems to be an easy one, though I didn't try the fix, just reviewed the code. So the cause of the issue is in MultiByteFileStream >> #basicChunk, which doesn't care about readLimit. When readLimit is less than "collection size", the end of the returned chunk may be the end of a previous chunk. This method has at least two other flaws (These probably won't hurt anyone in the near future, though both can be avoided): 1. if read buffering is disabled it will raise an error 2. it assumes that the encoding of the stream is ascii compatible Levente > > Cheers, > Henry >

Yes, this seems reasonable, as we should delete all references to Cursor. Do you agree with this ? If true we need to create an issue and commit :) Cheers Mariano On Sat, Jan 23, 2010 at 12:28 PM, Fernando olivero <oliverof(a)lu.unisi.ch>wrote: > Hi, i think this send to Sensor could be avoided by replacing the > Cursor>>show: method with > > Cursor>>show > self class currentCursor: self. > > > > > Instead of a: > > Cursor>>show > "Make the hardware's mouse cursor look like the receiver" > > Sensor currentCursor: self > > > InputSensor>>currentCursor: newCursor > "The current cursor is maintained in class Cursor." > > Cursor currentCursor: newCursor. > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >

[Pharo-project] Pharo screencasts - how to

by laurent laffont

Hi, I want to share how I record screencasts for Pharocasts http://pharocasts.blogspot.com/ in case someone wants to participate. Now there's 11 screencasts. The difficult part is to have a good idea / scenario for a screencast. Comments and ideas are welcome. If you want to publish on Pharocasts I can give you write access. Or if you have a "draft" screencast I can edit it / re-record it for publishing. I try to record screencasts with a minimum duration of 5 mn. These instructions are for Linux (but I'm a beginner in video stuff). I don't know which software to use on other operating systems. Have advices ? I record with xvidcap http://xvidcap.sourceforge.net/. I define a capture zone of 800x600 (use 4:3 or 16:9 standard resolution. If not you can have poor encoding results). Set multi-frame mode (you have to right-click on the file button to access preferences, not very intuitive). I choose AVI format / MPEG 4 codec. If you open / close applications for the screencast, note that KDE has very good options to memorize / force windows positions, so they are always opened in your capture zone.(Other window managers like E17 have these sort of options). The trick is to not stop recording when you write errors, you can cut the "wrong" parts later. To edit the video, I use avidemux http://fixounet.free.fr/avidemux/. It has Qt and Gtk GUI and work on Linux / Windows / OSX / BSD ..... It's really easy to use. When you want to cut a part, you define the beginning with the A button ( Ctrl-[ ), the end with B button ( Ctrl-] ), then Edit -> Cut ( Ctrl-X ). You can navigate using arrow keys. When finished, click on save (Choose another filename !!). So now you have your screencast in .mpeg file. Note that people using MacOSX Tiger or older have problems to watch this video. So I convert in .mov using ffmpeg http://www.ffmpeg.org/ like this: ffmpeg -i my_video.mpeg -b 500k my_video.mov. (but I think it's not the best command as the video size is bigger and quality lower). To publish the video I use Vimeo http://vimeo.com/. I've tried YouTube and Daily Motion but the quality is lower or the video duration is limited. I had problems using the "standard uploader", so I switch to the "basic uploader" on the download page, works better. It's really fun to record screencasts, and a good way to show development practices. Cheers, Laurent Laffont
