I am speaking only about drawing a box where we put the discussions on processing. Ii am naming people is just to remark the fact that there is people not only interested on this, but also working on this, meaning that to have a place for having this punctual disussions could be nice (just as a way of organising the discussions and having only informtion relevant to the processing thing. Still, i am aware that when we organise like this we are not organising for that, losing some freedom, and adding a complexity when gathering general information). What if we have links to all the groups in Pharo-project (pharo-misc, pharo-processing, pharo-robotics, pharo-web) ? I can do the firsts steps if we agree in here. > But we need indeed a general approach how to handle that.

Usually this is kind of a premature optimization to put groups and permissions and all of that on the table. If it comes to groups it comes to permissions and the management of them. You might try to solve a problem that might not even have. But you put the burden of managing memberships and permissions and that prevents collaboration to some extent So my golden rule to this is that if you donât have real good reason to add something like this organization, just donât. Wait until there is a problem. At that point you know what problem you have and you might have an appropriate idea how to solve it. This is very hard to do a priori. But we need indeed a general approach how to handle that. Every time someone asks me to be added to pharo-contributions Iâm thinking about if the setup is ok.

My report, some are the same than Esteban, as we work a lot together :D ### Last week: - (Pair Programming with Esteban) Modifying the TFFI callbacks to include information about the Smalltalk block in the plugin data structure. This improves the debugging experience and the detection of errors when a Callback in the image side is garbage collected. - (Pair Programming with Esteban) Compiling the Queue based ThreaddedFFI plugin to use the latest libffi version. This is required to build in Catalina. - (Pair Programming with Esteban) Adding synchronization code to correctly interrupt the AIO waiting idle loop. This is still work in progress as we have to test more scenarios. This modification allows us to extend enormously the idle time of the relinquish processor primitive without losing events nor delays. - (Pair Programming with Esteban) Fixing a glitch in GTK with the keyboard input and event handling when the GTK windows opened by Spec2 is the topmost of the application - Detection and fix of the GCC 8.3+ optimization glitch that prevented the built of the VM in newer Linux distributions. - Another iteration on the FreeTypeFont glitch issue. - Detecting all the requirements to use the Sista bytecode in the default image. This modification requires some changes in Fuel. There is a need for more changes in the debugger if we want to integrate full block closures. - Fixing small issues and reviewing PR for Pharo8 - Supporting Students in their modifications of the VM and experiments they are doing (Theo & Pierre here in Lille, and Federico in Buenos Aires): if you have problems just call :D. ### This week (starting 2019-12-16): - Pushing Pharo 8 release (Release Notes / PR / fixes) - Adding tests to the interruptable AIO and main thread worker of the headless VM. - Clean-up of code of the VM to allow to compile with MUSL and different libc implementations. This will allow us to run in Alpine Linux, improving the experience of Pharo running in containers. For doing so the correct way is to extend the debugging functions to allow different streams and outputs (today it is done through a hack, so we have to keep the behavior but implemented in a way that does not break the encapsulation of libc). - Working on GC tests with Guille.

TaskIt

by Santiago Bragagnolo

Hi everybody! We are starting to discuss with norbert about letting taskit to leave my incubator (my github account to go elsewhere). I have being thinking about it since long time, since i would like it to allow taskit to evolve into more than just my needs and wishes. The sidequestion i am bringing today it may seem (or even be) almost scholastic at this point, but i think it should have some space. The question is if to move it to pharo-contributions, or if to create a new pharo-processing. During the ESUG i came up with the idea/feeling/etc that it would be nice to have a group of people interested into processing (as hobby, duty, etc) for being able to push further this project and what-ever-other related project. During the conference i addressed norbert, tomohiro, mariano, matteo, guille, pablo, noury, (people for whom processing directly or indirectly is a primary concern) and i think there is even more people interested in this kind of general problematic, for what i sensed specially during my esug presentation. I think that to build a kind of team or group for discussing and working on this subject is a step in a direction that search to solve many modern daily problems that pushes us out of larger models of business and interaction (cloud and derivatives). Having this points in mind i think that the choice of this new github project could be a good point to start a to work on this goal (as a first place of gathering). Still, i would like to hear other's opinion, in order to be able to deal with this maybe before new year :). Thanks for your time and reading :) Santiago
