Hacking during the switch from DST to normal time forced the user to wait one hour. Opening images from different time zones did also show this bug. What?! Time millisecondClockValue is supposed to be continuous. I’ll have to admit I didn’t follow the previous discussion too closely, but syncing millisecondClockValue to the wall clock seems like a very bad idea. - Bert -

AW: [squeak-dev] [ANN] The Squeak 5.1 Release Plan
by Herbert König 17 Jul '16

17 Jul '16

Really exciting news! Herbert <div>-------- Ursprüngliche Nachricht --------</div><div>Von: "marcel.taeumel" <Marcel.Taeumel(a)hpi.de> </div><div>Datum:13.07.2016 10:29 (GMT+01:00) </div><div>An: squeak-dev(a)lists.squeakfoundation.org </div><div>Betreff: [squeak-dev] [ANN] The Squeak 5.1 Release Plan </div><div> </div>Hey, there. I just want to inform all of you that we are in the middle of preparing the next Squeak 5.1 release. We are working on automation for generating/updating all release artifacts so that we are eventually able to shorten our release cycle in the future. For this, we are using smalltalkCI (thanks Fabio!), TravisCI, and AppVeyor. Here are the important dates: * Feature Freeze on July 31, 23:59 AOE * Code Freeze on August 14, 23:59 AOE * Release between August 15 and 19 As these dates suggest, our goal is to have the release before this year's ESUG. However, there is another important Smalltalk-related event this year: 20 years of Squeak. :-) Yeah! It was around October 1996, when the first Squeak came into the world. ...having its own worlds. :D So, it would only make sense to also have a special release for this birthday. For this, we revived all of the cool multimedia content, known from Squeak 1 through Squeak 3, and made it fit for the current Squeak code base. Oh, this is so exciting. :-) Anyway, what's with Squeak 5.1 and 64-bit? Since the release of Squeak 5.0, we've been working hard and made a lot of bug fixes and added some features to improve the overall usability and robustness of the Squeak live programming system. Meanwhile, the VMs improved as well. Cog's object format "Spur" got more robust, the JIT improved, and the whole code base moved from SVN to Git: https://github.com/OpenSmalltalk/opensmalltalk-vm. Still, what's up with 64-bit? We have working 64-bit VMs for Mac OS X and Linux. Hence, we will take the chance and also release 64-bit bundles for Squeak 5.1. Be informed that this means a new .image file. You cannot open a 64-bit .image with a 32-bit VM and vice versa. This, however, is nothing serious because we are working on an updated version of our SystemTracer to convert back and forth. With limitations, of course. ;-) You cannot fill a bottle of beer into a shot glass. What's up with the All-in-one? There will be the usual 32-bit all-in-one package, which combines VMs for Linux, Mac OS X, and Windows. Since there will be no 64-bit Windows VM within the next two months, we refrain from creating an almost-all-in-one-32/64 package. This would only confuse the users. In the future, we can arguably expand the concept of the All-in-one to also contain 32-bit and 64-bit VMs and images. So, what are the prospective release artifacts for Squeak 5.1? * All-in-one (Linux/Mac/Win) 32-bit * Mac OS X App 32-bit, signed * Mac OS X App 64-bit, signed * Linux Bundle 32-bit * Linux Bundle 64-bit * Windows App (maybe with MSI Installer) 32-bit, maybe signed * ZIP archive containing .image and .changes, no VM, no .sources We plan to also use the new release automation process for Squeak 5.0 and update those release artifacts as well. We will update our squeak.org Website but you will always find the artifacts on http://files.squeak.org/5.0 and http://files.squeak.org/5.1 . :-) Best, Marcel -- View this message in context: http://forum.world.st/ANN-The-Squeak-5-1-Release-Plan-tp4906439.html Sent from the Squeak - Dev mailing list archive at Nabble.com.

rice paper background in trunk?
by Eliot Miranda 17 Jul '16

17 Jul '16

Hi All, how do I set rice paper as the background as opposed to this drab grey? Marcel told me once but I think I deleted the email. I can't find anything on lists.squeakfoundation.org. Sorry for the noise. _,,,^..^,,,_ best, Eliot

CFP: 1st Workshop on Meta-Programming Techniques and Reflection (META) with SPLASH 2016
by Stefan Marr 15 Jul '16

15 Jul '16

**Call for Papers** ======================================================================== 1st Workshop on Meta-Programming Techniques and Reflection (META’16) Co-located with SPLASH 2016 October 30, 2016, Amsterdam, Netherlands http://2016.splashcon.org/track/meta2016 Follow us on twitter @MetaAtSPLASH ======================================================================== The Meta’16 workshop aims to bring together researchers working on metaprogramming and reflection, as well as users building applications, language extensions such as contracts, or software tools. With the changing hardware and software landscape, and increased heterogeneity of systems, metaprogramming becomes an important research topic to handle the associate complexity once more. Contributions to the workshop are welcome on a wide range of topics related to design, implementation, and application of metaprogramming techniques, as well as empirical studies on and typing for such systems and languages. ### Important Dates 08 Aug 2016 - Abstract Submission 15 Aug 2016 - Paper Submission 05 Sep 2016 - Notification 09 Sep 2016 - Demo, position or work-in-progress paper submission 23 Sep 2016 - Demo, position or work-in-progress paper notification 30 Oct 2016 Workshop ### Topics of Interest The workshop is a venue for all approaches that embrace metaprogramming: - from static to dynamic techniques - reflection, meta-level architectures, staging, open language runtimes applications to middleware, frameworks, and DSLs - optimization techniques to minimize runtime overhead - contract systems, or typing of reflective programs reflection and metaobject protocols to enable tooling - case studies and evaluation of such techniques, e.g., to build applications, language extensions, or tools - empirical evaluation of metaprogramming solutions - security in reflective systems and capability-based designs - meta-level architectures and reflective middleware for modern runtime platforms (e.g. IoT, cyber-physical systems, mobile/cloud/grid computing, etc) - surveys, conceptualization, and taxonomization of existing approaches ### Types of Submissions and Workshop format We welcome both technical papers and work-in-progress and position papers from the academic as well as industrial perspective. Position paper should present new ideas and emerging problems and take a perhaps controversial stance on a specific topic and argue the position well. Furthermore, we plan interactive brainstorming and demonstration sessions between the formal presentations to enable an active exchange of ideas. The workshop papers will be put on the workshop website, if not requested otherwise by the authors, but they are not part of formal proceedings. Papers are to be submitted using the ACM sigplanconf style at 10pt font size. See http://www.sigplan.org/Resources/Author/. - demos and posters: 1-page abstract - position and work-in-progress paper: 1-4 pages - technical paper: up to 8 pages Demos, posters, position and work-in-progress papers can be submitted on a second, later deadline to discuss the latest results and current work. For the submission, please use the submission system at: https://meta16.hotcrp.com/ ### Organizing Committee Shigeru Chiba, University of Tokyo Elisa Gonzalez Boix, Vrije Universiteit Brussel Stefan Marr, Johannes Kepler University Linz ### Program Committee Marcus Denker, INRIA, France Robert Hirschfeld, HPI, Germany Hridesh Rajan, Iowa State University, USA Romain Rouvoy, University Lille 1 and INRIA, France Eric Tanter, University of Chile, Chile Tom Van Cutsem, Bell Labs, Belgium Tijs van der Storm, CWI, Netherlands Takuo Watanabe, Tokyo Institute of Technology, Japan

OpenWeatherMap.org api?
by tim Rowledge 15 Jul '16

15 Jul '16

I don’t suppose anyone has already written stuff to connect to www.openweathermap.org site? I’ve found python code that claims to suport it (but it makes little sense to me so far) at https://github.com/presch/python-openweathermap-api/blob/master/package/pyo… It would be nice to be able to do similar directly from Squeak. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Maybe Computer Science should be in the College of Theology

spyOnWorldFor:
by Yoshiki Ohshima 14 Jul '16

14 Jul '16

I am trying a few things on Squeak 5.0. In earlier versions there was AndreasSystemProfier (formerly known as QSystemProfier) and had a method called spyOnWorldFor:, which was quite useful. I just loaded AndreasProfier-eem.11.mcz and tried it but it crashed the 5.0 all in one VM on Mac OS 10.10. Is this a known issue? Is there an alternative to it? -- -- Yoshiki
