Create png from pdf
by Sabine Manaa Jan. 19, 2017

Jan. 19, 2017

Hi, currently, I create pdfs with Artefact and it works fine. For displaying previews of the pdf reports, I use Apache PDFBox to generate pngs from the pdfs. This works, too. But I would prefer to generate the pngs directly from pharo and do not call external libraries. Stephane told me that "there is a form in a morph and it can be converted in png". Can anyone give me a small entry point or has done similar and provide some code snippet?

Of all the great things i have seen added to pharo over the past years, the absolute coolest i have yet seen is the addition of a hotkey sequence for âSave Imageâ..

Big List of Naughty Strings
by Sven Van Caekenberghe Jan. 16, 2017

Jan. 16, 2017

This might be interesting to some people for testing purposes. You all heard stories how certain input caused certain systems to crash. Here is someone who collected lots of these strings. Big List of Naughty Strings https://github.com/minimaxir/big-list-of-naughty-strings Luckily, Pharo can at least read them all in, without problems, as far as I can see. 'https://raw.githubusercontent.com/minimaxir/big-list-of-naughty-strings/mas…' asUrl retrieveContents lines. Sven PS: You won't see all the weird/exotic Unicode characters (choosing a different font like Arial Unicode MS shows a lot more).

Hi, Thanks, that's very nice.

Hi, Pharo 4 might be hard on MacOS Sierra. There was a late change to the VM, at least for Squeak, to stop the black screen on startup on Sierra.Â Â Â Pharo 4 was before that change, and, for that matter, before Sierra.Â Pharo 5 was after and clearly has that change. I'm pretty sure that the patches are one of these two: [https://github.com/OpenSmalltalk/opensmalltalk-vm/...](https://github.com/O… [https://github.com/OpenSmalltalk/opensmalltalk-vm/...](https://github.com/O… and I'm almost 100% sure that the second is the magic one.

So it would look as if one's choices are: * Build the version of the VM from the Pharo 4 bundle, but, apply one or both of the patches above. * Figure out why Pharo 4 is necessary and move to Pharo 5. * Run a squeak V3 VM and hack something together.Â This might not give the full Pharo experience. To run the squeak V3 do the following: Download and unzip the newest Squeak V3 VM.

Older Pharo on MacOS Sierra
by J.F. Rick Jan. 14, 2017

While Pharo5 works in Sierra if I place it in the Applications directory, older Pharo versions don't. While the image opens, I just get a giant black window. Any way around this? Happy New Year! Jeff

SPLASHâ17 Call for Contributions: Workshops
by Ronald Garcia Jan. 14, 2017

Jan. 14, 2017

/************************************************************************************/ ACM Conference on Systems, Programming, Languages, and Applications: Software for Humanity (SPLASH'17) Vancouver, Canada October 22-27, 2017 http://2017.splashcon.org <http://2017.splashcon.org/> Sponsored by ACM SIGPLAN /************************************************************************************/ CALL FOR CONTRIBUTIONS: Workshops /************************************************************************************/ ## SPLASH Workshops Following its long-standing tradition, SPLASH 2017 will host a variety of high-quality workshops, allowing their participants to meet and discuss research questions with peers, to mature new and exciting ideas, and to build up communities and start new collaborations. SPLASH workshops complement the main tracks of the conference and provide meetings in a smaller and more specialized setting. Workshops cultivate new ideas and concepts for the future, optionally recorded in formal proceedings. ## Call for Submissions: We encourage proposals for workshops on any topic relevant to SPLASH. If there is a topic relevant to SPLASH that you feel passionate about, and you want to connect with others who have similar interests, you should consider submitting a proposal to organize a workshop! The exact format of the workshop can be defined by the proposal submitters, and we more than welcome new, and unconventional ideas for workshop formats. The following suggestions may serve as a starting point: - Mini-conferences provide their participants the possibility to present their work to other domain experts. The smaller and more specialized setting of the workshop allows for more extensive Q&A sessions and facilitates ample discussions,which may continue after the workshop. Typically, presentations of work-in-progress as well as of completed projects are welcome. The workshop may or may not produce formal proceedings. - Retreats act as a platform for domain experts to gather with the purpose of tackling the issues of a predetermined research agenda. Retreats are highly interactive and goal-oriented, allowing their participants to address open challenges in their domain, to explore new, uncharted ideas, and to (maybe even) uncover new, promising research domains. - Agenda-setting workshops provide a forum for domain experts to determine a research agenda for a sub-field, and may include collaborations on an agenda document that is published after the workshop is over. Other common activities at workshops include poster sessions, hands-on practical work, and focus groups. Proposal submitters should feel free to direct questions about workshop formats to the workshop chairs. Workshops that include presentation of research papers, and that implement a SIGPLAN-approved selection process, may be archived as formal proceedings in the ACM Digital Library; note that this option is available only to submitters to the early phase. ## Workshop Submission Phase: This year, SPLASH provides two options to submit proposals, either Early Phase or Late Phase (but not both): Early Phase Submissions due: 20 January 2017 Late Phase Submissions due: 3 March 2017 ## Information Website: http://2017.splashcon.org/track/splash-2017-Workshops <http://2017.splashcon.org/track/splash-2017-Workshops> Email: workshops(a)splashcon.org <mailto:workshops@splashcon.org> ## Organization: SPLASH General Chair: Gail Murphy (University of British Columbia) OOPSLA Papers Chair: Jonathan Aldrich (Carnegie Mellon University) Workshops Co-Chairs: Craig Anslow (Middlesex University, London) and Alex Potanin (Victoria University of Wellington) /************************************************************************************/
