We do not control anything on that side. This is FUN that is changing and managing all that. This is why we should get autonomous. > Are the videos still on youtube? I could not find them again. No ideas. Normally they should be on canalU.

What do you mean? Because since the videos are quite large in fact we have this special server.

I do not really understand what you mean. - for us youtube can throw away our videos we want to have a server with them - then CanalU and Unisciel can have them - Unisciel prefers to have a webportal so we did one for them. - I'm not a big fan of Php :) so I would like to avoid to have to maintain the WebPortal this is why what you are doing is really cool because I would like to be able to package it and put it on large USB stick and send it to all the teachers I know. > I have a put up a preview on > https://siemenbaader.github.io/PharoMooc-website/. > > What do you think?

Re: [Pharo-users] MOOC TOC cleanup

by stepharo

Hi siemen Please pay attention that I have to check the following: MoocLab which produces the mooc has a private production repository for the videos and I do not understand but the videos there are much larger there than on the http://rmod-pharo-mooc.lille.inria.fr/ <http://rmod-pharo-mooc.lille.inria.fr/MOOC/Videos/W1/C019SD-W1-sous-titres-…> I do not remember if we downloaded the videos from the official mooc web site (FUN) and that they did some preprocessing that reduced the size of the videos that they got from MoocLab. I would need some help to see if - the videos on France UniversitÃ© Numerique are better quality than the one on http://rmod-pharo-mooc.lille.inria.fr/ <http://rmod-pharo-mooc.lille.inria.fr/MOOC/Videos/W1/C019SD-W1-sous-titres-…> Stef Le 11/11/16 Ã 08:47, Siemen Baader a Ã©crit : > Hi Offray, > > I'm not sure if this answers your question, but: the French and > English subtitle files in .vtt and .srt format are already online in > directories like > http://rmod-pharo-mooc.lille.inria.fr/MOOC/Videos/W1/C019SD-W1-sous-titres-… > and similar.

Re: [Pharo-users] Pier3 with latest Pillar?

by Jupiter Jones

+1 from me, and would love to help where I can. It would be nice to see Pillar return to being a cross platform project as well. One of the beautiful things about Seaside/Magritte/Pier was itâs compatibility across many dialects of Smalltalk. The âdevelop in Pharo and deploy in GemStoneâ was a big draw for me :) One of my clients uses VW so it was great to have these projects there as well. Pillar was refactored to use Traits and save duplication of (from memory) about 3 methods, but in doing so it became a Pharo-only project. I asked about this and found there wasnât an interest in maintaining cross platform compatibility, so I saved a copy on git hub [1] and added a PRPillarGemstoneCodeTool class with a simple method for flattening the traits. My hope was being able to maintain a cross platform version of Pillar and keep Pier updated in a manageable way. Frustratingly, my work only allows me the occasional sprints in Smalltalk and without a Pier project to work on, I havenât had the resources to keep it updated. Iâd like to see Pier get some love - itâs an awesome tool. How can I help?

Re: [Pharo-users] Progress Bar with unknown state or showing animated gifs

You can take a look at how I do seconds indicator in my ChronosManager tool, its just a simple ImageMorph stepping through png images with transparency.

Dues anybody try Artifact with non latin characters?

by Denis Kudriashov

Hi. I need to generate PDF with russian letters but when I try it resulting pdf is empty. I use example: oneLineTest: aStream PDFDocument new add: (PDFPage new add: (PDFTextElement new text: 'Hello ÐÑÐ¸Ð²ÐµÑ'; from: 10mm@10mm)); exportTo: aStream. I attach produced pdf. Best regards, Denis

Progress Bar with unknown state or showing animated gifs

by Peter UhnÃ¡k

Hi, is there a way to have a progress bar with unknown state? e.g. https://i.stack.imgur.com/gz9GK.gif ProgressBarMorph / Job / SystemProgressMorph seem to be based around progress only. Alternatively, is it possible to (easily) display animated gifs? Thanks, Peter
