[Spec] Issue with toolbar button width
by Hilaire April 9, 2020

April 9, 2020

Hi, I am sketching the final touch on what will be a DrGeo workspace for kids. I am using a dedicated toolbar and I have issue with the button label: they are cut and their width seem to be somehow maximized. See bellow: By the way, Spec is quite a productive framework. Good work. Hilaire -- Dr. Geo http://drgeo.eu

[Mm10s] 2020-04-06
by Esteban Lorenzano April 6, 2020

April 6, 2020

Morning. Last week was kind of slow. Lots of (personal) things to take care that took more time than expected: kids, basement flood, etc. Anyway, this is what I managed to achieve: ### Last week * [spec2] add "align" property to box layouts (so you can center, or align right, etc.). * [spec2] SpTextPresenter now respond also to âeditableâ property (different than âreadonlyâ. * [spec2] add popover component (took more time than expected ;) ). * [spec2] SpCodePresenter now accepts insertPopoverAfterSelection: * review and accept (most) of all pending PRs from Spec2 ### This week (starting 2020-05-06): (Still stuck in the same) * [idlevm] more on the revamp of callbacks * [spec2] enhance SpMenuPresenter (to allow checkboxes and etc.) * [spec2] more on SpCodePresenter * [newtools] more on StPlayground

I should have initially posted this to the Pharo-dev list, as well. From: Pharo-users [mailto:pharo-users-bounces@lists.pharo.org] On Behalf Of Shaping Sent: Friday, 3 April, 2020 14:05 To: 'Any question about pharo is welcome' <pharo-users(a)lists.pharo.org> Subject: Re: [Pharo-users] Latest PharoJS Success Story; Wasm/WASI; very keen on Pony for the Pharo VM All: > Brain Treats got stuck during launch on my LG. > Which android version are you using ? The phone is old and this is likely the problem. Android version: 4.4.2 Kernel version: 3.4.0 > Is there a plan to move PharoJS to Wasm/WASI? > Dave and I talked about it a long time ago. This sounds like a good idea. Actually, Dave has a very ambition idea = turn PharoJS into Pharo* where * can be different targets. But, there's a lot to do before reaching this goal. So, don't expect it any time soon. Not to change the topic too much, but the following is related and I often think of it. Consider writing the pharo VM in Wasm or, better, with Pony (which can emit Wasm, as needed). Pony's reference-capability-based (ref-cap) concurrency-model guarantees provably that no data-races or deadlocks can happen if the code compiles; this solves a very large class of extremely ugly concurrency problems that no one ever wants to face. Pony gives high-performance concurrency (5 to 15 ns actor-thread switching time, depending on platform), and solves the most difficult class of synchronization problems at compile time. It runs as fast as C. It runs faster than C, as concurrency scales. You can't scale a highly concurrent app efficiently in C, and really shouldn't try if you wish to remain happy and mentally healthy. Pony is still pre-1.0, but the group is very active and competent. I think we should consider using it to build the VM. Have a look. Some videos for your amusement and information: https://www.youtube.com/watch?v=ODBd9S1jV2s https://www.youtube.com/watch?v=u1JfYa413fY https://www.youtube.com/watch?v=fNdnr1MUXp8 https://www.ponylang.io/ There are many others. I mentioned the Pony concurrency architecture around the holidays, but there was no interest from the list-not a good time perhaps. The tentative plan is to do what Google does with Flutter: have the JIT in support of the usual dynamicity a Smalltalker needs for rapid development; and have AOT, fully optimized compiling for production or speed-related reality checks, presumably needed less often during development. There are other possibilities. Anyone interested? I have some ideas for simplifying use of the six ref caps in the context of Pharo/Smalltalk. If this path is chosen, one must commit to strict state-machine-based algorithm development, without exception. This should have happened anyway by now, broadly in the programming space, but didn't. I'm working on a programming graphical tool and associated grammar (in VW) that make state-machine development easy and attractive. This , besides efficient use of machine resources, is the other reason for pushing in this direction. A Pony program is built from a net of asynchronously communicating actors. You change the state of your program with asynchronous messaging between actors. There is no blocking--no mutexes or semaphores-and therefore no wasted CPU cycles or mushrooming program complexity, as you try to use mutexes in a fine-grained way (a very bad idea). And as mentioned, there are never deadlocks or data-races. All cores on all CPUs stay busy, always, until the program goes idle or exits. The Pony group is also working on extending the model to the network level, so that all machine nodes in the network stay busy. In the round, as a start, think of Pony as Erlang/OTP, but much faster, with no legacy bugs, and provably no-deadlocking on compile. The asynchronous actor model is the programming pattern that Kay had in mind when he said "object-oriented." It's the one I want to implement in Pharo. The green threads are light, but don't efficiently use the cores, and a net of VMs with their respective images still communicate too slowly. I your time permits, please study Pony for a bit, before rejecting the idea as too big a change in direction or too complicated. Using Pony looks like the ideal VM simplification strategy, if our aim is efficient use of networks of machines, each with at least one CPU (often more), each, in turn, with many cores (whose numbers are still increasing). This pattern in hardware probably won't be changing much, now that speeds are topping out. Winning the performance game is therefore about efficiently using many cores at once, without burdening the programmer. I don't see a better way to do this now than with Pony. Thoughts and suggestions are welcome.

My *personal* take on this is is that we can migrate easily the catalog, without deprecating it: - the catalog repositories will stay alive as read-only, so it will be no problem to access old catalog entries (unless they depend on private projects, but that would be odd) - a low-energy solution for this is to migrate these repositories to squeaksource3. This should be mostly straight-forward. - a high-energy solution is to rethink the catalog. I know there have been some community efforts from Christophe Demarey for example, Esteban has also interesting ideas on how to attack this.

[ANN] SmalltalkHub Deprecation Notice
by Guillermo Polito April 3, 2020

April 3, 2020

SmalltalkHub Deprecation Notice SmalltalkHub is now getting old and it is time to deprecate it. We plan to replace it by a static file server during 2020. The public data will still be readable and consumable from monticello clients, but modifications will not be allowed in the near future. SmalltalkHub users should move their projects to git repositories or other monticello repository services. What is changing? If you currently host a project in SmalltalkHub, you should migrate your projects to another platform as soon as possible. If you depend on a project hosted on SmalltalkHub, you should contact the owner of that project to schedule a migration. If you have documentation or tutorials using SmalltalkHub, we recommend to update those after a migration. An archive of all public projects in SmalltalkHub will be made available in read-only mode. This archive will be readable through monticello clients for compatibility reasons. Private projects, due to privacy reasons, will not be published in the public archive and will be removed to protect their owners. Why are RMoD and Inria making this change? SmalltalkHub has finished its cycle. The arrival of git integration in the past years caused the move of most users in the Pharo community to git hosting services. They now use exclusively other platforms. Furthermore, RMoD and Inria lack the manpower to properly maintain the SmalltalkHub service and keep it up to date. Smalltalkhub has no added value compared to other code source hosting platforms. How much time do I have to adapt to this change? The SmalltalkHub deprecation will follow the next timetable: Monday 04 of may 2020: SmalltalkHub will be read-only. Creation of new users and projects will be forbidden. New commits will be rejected. All existing users, projects (public and private) and their commits will remain available and visible, but their settings will become read-only. Monday 02 of november 2020: SmalltalkHub will be migrated to a static file server archive. Private projects and their commits will not be available anymore. The RMoD team and Inria plan to keep the static file server alive for, at least, 5 years from the date of its creation. What will happen if I do nothing? Your public projects will become read-only and you will not be able to commit anymore. Your private projects will become unavailable. What alternatives do I have? Those wanting to keep using monticello can migrate their projects to other monticello hostings such as http://squeaksource.com <http://squeaksource.com/> or http://ss3.gemstone.com <http://ss3.gemstone.com/> Those wanting to migrate to git, Peter Uhnakâs git migration tool (https://github.com/peteruhnak/git-migration <https://github.com/peteruhnak/git-migration>) automates monticello to git migration in tonel format.
