[ANN] Pyonkee is available on App Store
by Masashi UMEZAWA 29 Aug '14

29 Aug '14

Hi all, I have just released a Scratch clone running on iPad. It is based on Scratch 1.4 from the MIT Media Laboratory. The app is now called "Pyonkee" - freely available on App Store. https://itunes.apple.com/us/app/pyonkee/id905012686 Pyonkee was originally started as a fork of John M McIntosh's Scratch Viewer. https://github.com/johnmci/Scratch.app.for.iOS. While Scratch Viewer just works as a viewer of the existing Scratch projects, Pyonkee supports creation/edit of projects. Other features: - User interfaces are optimized for iPad - Native font support - Embedded camera support - IME support - Auto-saving project - Sending projects via e-mail - Project import/export through iTunes (currently disabled) Moreover, source code is open on github. Feel free to fork it. https://github.com/SoftUmeYa/Pyonkee Enjoy! -- [:masashi | ^umezawa]

I would not be surprised if it is something to do with wide characters. I vaguely recall that we fixed a similar sounding problem elsewhere in the system recently. Unfortunately I cannot remember what it was. In any case, I am attaching a png of the debug window for the problem as I encountered it last weekend. This will need to be turned into a repeatable test case. Dave

What's up on build.squeak.org
by Nicolas Cellier 27 Aug '14

27 Aug '14

Hi, it seems that most of the builds are red for 2 months. I checked the last artefact for squeak trunk: http://build.squeak.org/job/SqueakTrunk/853/ It's still blocked with the [Warning signal: 'About to serialize an empty package.'] With this warning, a test never time out (I don't know why exactly, but it seems that theProcess monitored by the timeout watchdog is already suspended by the Warning) As a result, the tests do never complete and are aborted after 20 minutes... Chris has fixed the problem since, but it seems that the CI does not upload latest trunk. Why? It seems to be the same problem as the TestRunner: updating triggers the same [Warning signal: 'About to serialize an empty package.'] Ah Chris, it's irony that it's you who precisely keep on fighting modal UI ;) Now the question: how do we escape from this situation? Shall I cheat and modify the update that is blocking?

MutliByteFileStream - failing test fixed
by Chris Cunningham 26 Aug '14

26 Aug '14

Hi. I would move to include MultilingualTests-cbc.19.mcz <http://source.squeak.org/@DkMJpXbIY68oFww2/AiqHJsnF?31> (which makes the failing test omre informative) Multilingual-cbc.201.mcz <http://source.squeak.org/@DkMJpXbIY68oFww2/AiqHJsnF?25> (which fixes the source so the test doesn't fail) This is rather a brute-force approach to fixing the test, although if you want the legacy behaviour (ignoring line ending), either don't set a line ending converter, or pass wantsLineEndConversion: false to the stream; in either of these cases, the new logic would be bypassed (correctly) and there should be no peformance hit at all. There could be otherwise; if anyone notices one, let me know - i have an idea how to deal with it, but would rather not until someone NEEDS it. -cbc (ps - could someone with Developer/Admin access please delete Multilingual-cbc.200.mcz <http://source.squeak.org/@DkMJpXbIY68oFww2/AiqHJsnF?28> from the inbox? It is wrong.)

[Survey] State of the Art in Debugging
by Michael Perscheid 25 Aug '14

25 Aug '14

Dear all, A student of us is working on the topic of debugging and how it works today. Therefore, please find attach his mail with the request to answer his questions. Dear Sirs or Madams, since 1974, researchers and software developers try to ease software debugging. Over the last years, they created many new tools and formalized methods. We are interested if these advancements have reached professional software developers and how they influenced their approach. You can help us answering that questions by taking part in our online survey. It will take about 10 to 15 minutes and is fully anonymous. You can reach it under https://www.uni-potsdam.de/skopie-up/index.php/689349 Thank you for your interest, Benjamin Siegmund Thanks in advance! Best regards, Michael --- Michael Perscheid michaelperscheid(a)googlemail.com http://www.michaelperscheid.de/

Re: [squeak-dev] The Trunk: Morphic-cmm.743.mcz
by Chris Muller 25 Aug '14

25 Aug '14

This time I moved all the abadoned ancestry to the Treated Inbox so that we won't be inclined to re-adopt them again. All mcm's since dtl.283 were fixed to not point to the bad Morphic package. My god what a mess.. I don't know if I have magic pixie dust in my package-cache or not but... I am able to update from a 4.5-13686 image to a 13918 trunk cleanly, no errors or dirty packages.

Changes to Trunk (http://source.squeak.org/trunk.html) in the last 24 hours: http://lists.squeakfoundation.org/pipermail/packages/2014-August/007260.html Name: Morphic-cmm.740 Ancestors: Morphic-cmm.738 Re-fixed the Morphic ancestry mess. Please do not re-adopt anything from kfr.732 to mt.742. All changes which didn't break something have already been manually included. It's too bad we lost the historical record for those changes, but its better than a broken trunk. ============================================= http://lists.squeakfoundation.org/pipermail/packages/2014-August/007261.html Name: Morphic-cmm.743 Ancestors: Morphic-cmm.740 Forgot to resave as the highest number dammit. =============================================
