Hi alain This is great to know that you can now work officially on Bloc and I really hope that your project with Thales will succeed. We need a strong Pharo. After more than 5 years of discussions with Thales I'm happy to see coming truth. People do not imagine the amount of energy we can spend sometimes :) And indeed you are right! I was sad to see that you are not even part of the github team after all the effort you spent on Bloc (and Miro and Miro2). I think that I was just the guy asking stupid questions but indeed this is true that it was in collaboration with Rmod, thank to mention it. I also agree with you that this is important that your work is respected and acknowledged and indeed I do not see how it relates to humane assessment.

[ann] bloc & cairo+morphic
by Tudor Girba May 11, 2017

May 11, 2017

Hi, We are happy to announce that based on the work of Glenn, Alex extended Bloc (Sparta) to work directly in the Morphic world using Cairo as a backend. Cairo is less powerful than Moz2D (see the screenshot below for an example), but the implementation addresses a concern that the community raised regarding a perceived increased liability due to the dependency to Moz2D. Essentially this means that Bloc can be treated as another graphical library that can coexist with Morphic without requiring any external VM plugin. I would also like to point out that adding a new backend and host was possible because of the many iterations (including throwing away whole implementations) that Alex and Glenn went through. I think they did an amazing job. You can find a bit more details about Bloc here: http://www.humane-assessment.com/blog/bloc-flexible-backends-hosts/ Another issue raised regarding Bloc was that of the engineering effort required to make it a reality. That is why I would also like to announce that Alex joined feenk.com where he is primarily working on the graphical stack for Pharo.

[Zinc] How do I set the entry limit for ZnMultiValueDictionary?
by Max Leske May 11, 2017

May 11, 2017

Hi, I'm performing a legal request that has more than 4000 parameters. This causes the Zinc server to return 400: Bad Request because ZnMultiValueDictionary is limited to 256 entries by default. The dictionary has the option to remove the limit or to adjust it with a dynamic variable. Unfortunately, I don't see any way to properly configure this without monkey patching Zinc. Ideally, I'd like to remove the limit (which can't be done through the dynamic variable by the way because when the dynamic variable answers nil, the default will be set to 256). The first thing that comes to mind is to move this setting to ZnConstants, but then I don't see any way to configure ZnConstants either (ZnConstants is referenced directly by its users). Maybe ZnConstants could be changed to hold a concrete constants class (itself by default). In any case, I think this setting should be configurable and the configuration should be possible through one single entry point, together with options like #codec. Thoughts? Cheers, Max

Missing plugins to make the vmProfiler work on Pharo
by Sophie Kaleba May 11, 2017

May 11, 2017

Hi Esteban, Hi all, I am working on porting the Squeak VMProfiler to Pharo as a gsoc (I will post a more detailed presentation about that in the mailing list later today). While trying to use the profiler with the Pharo VM, I get the following error : "PrimitiveFailed : primitive #primitiveExecutableModules in VMProfilerLinuxSymbolsManager failed". (see stack trace attached). This plugin (VMProfileLinuxSupportPlugin) does not seem to be included by default in the Pharo VM (it works with a Squeak VM). I haven't tried on a mac, but I guess the plugin (VMProfileMacSupportPlugin) is missing too. For the moment, I am using the latest Squeak VM with my Pharo image but it is not quite convenient. Would it be possible to include the 2 plugins to the Pharo VM ? If I can be of any help, just tell me Thanks! Sophie

GSoC 2017 Introduction
by Myroslava Romaniuk May 10, 2017

May 10, 2017

Hello everyone I have been accepted as a GSoC student and my project is Advancing in Pharo Quality Support. Here <https://docs.google.com/document/d/1cX7VJ2QZejq_Cu6Ur28UCiUwzSD-Bu8GgSDqECi…>'s the link to my proposal, if you have any suggestions feel free to comment or send me an email, I would really appreciate some feedback. Here are also links to my github <https://github.com/myroslavarm> and linkedin <https://www.linkedin.com/in/myroslavarm/>. In short, my project consists of several subprojects: - updating rules (improving hints, moving the rules to corresponding packages) - advanced rule toggle (a functionality to enable/disable rules from Pharo settings, a shortcut to ban a rule globally) - smart error handling (display errors that occured during critique computation along the actual critiques) - match-rewrite tool (combines features of matchtool and rewritetool, improves the process of inspecting, creating, editing and removing rules) - pre-commit quality feedback (an extension to either monticello or iceberg that will show modified parts of a project and critiques related to them --- if I have time) - making rules more maintainable while reporting encountered bugs Thanks very much for this amazing opportunity to be working with all of you, and for the help you're providing us, GSoC students, with - on Discord and in the mailing list. Looking forward to the amazing summer with the Pharo community! -- Myroslava
