I just load the baseline with no version specified. If that works for you, maybe we should release another versionâ¦

Sponsoring our new mooc

by stephane ducasse

Since more than a year we have been working on a new mooc called: âAdvanced Object-oriented Design and Developmentâ It will be quite good. We are bullet proofing it with a new lecture here at Lille. It will not focus on Pharo but on object-oriented design, tests, design patterns. It will present - Test and test-driven - Essential aspects of OOP - Basic and universal principles - Double dispatch - Case studies in Pharo - Some design patterns - Some coding idioms and we will composed of 8 modules Currently it has around 50 lectures and we expect around 60 + exercises. You can access some drafts of the support here: https://rmod-files.lille.inria.fr/?dir=DesignCoffeeClub <https://rmod-files.lille.inria.fr/?dir=DesignCoffeeClub> The production cost of this mooc is around 200 K Euros financed by Inria and it will be filmed in January. We hope to deploy it in April or May 2023. The mooc will be produced in english (and may be dub in french). It occurred to me in this difficult time to find good developers that some of you may want to sponsor this mooc\to get exposure. You can be associated with some of the best OO teachers: me, Guillermo Polito and Pablo Tesone. We have cumulated more than 40 years of teaching experience. Several books... Yes at the end of the day we should sale a bit our expertise - check below our track record with the previous mooc. As a sponsor you will get your logo and links on all the supports: Slides and videos. Note that this mooc is designated to have a live time of 10 years or more. It is teaching fundamental points of OOP. So this is a unique opportunity to market your company to people wanted to learn advanced OOP Note that there are no other lectures like this one. We have two levels of sponsoring: 2000 Euros for platinum sponsor 1000 Euros for plain sponsor Let us know. Just a little reminder of the previous Mooc on Pharo. It has more than 8 years. For the record, some youtube videos (that we published after 4 years of running the pharo mooc) got more than 6000 views and this is by developers. We got around 10000 followers not counting the people watching the mooc on youtube and here are some of the testimonies we collected over the years. J'ai trouvÃ© Ã§a trÃ¨s intÃ©ressant, beaucoup plus que prÃ©vu ! je regrette de ne pas m'y Ãªtre mis plus tÃ´t. J'ai enfin l'impression de vraiment faire de la POO ! Ou Ã l'inverse je me rend que je n'en faisais pas vraiment... - Anonymous, 2019 I have just completed week seven of the Pharo Mooc (beginner and object oriented tracks) I am starting a redo of the Mooc with the web track (TinyBlog project). I have already learned so much ! I have spent the last 20 years or so in software development and, following this Mooc, I realized I hadnât really grasped the essence of object oriented design. - Anonymous Â« Really one of the best mooc I have ever attended. And I have attended quite a few (openSAP, openHPI). As an old fashioned ABAP developer I want to be reborn as Pharo developer in my next life :-) Â» - Anonymous Hi! I finished the MOOC some weeks ago and I would like to congratulate everybody involved! After a decade+ of Python programming I think I found my new favorite language :). I'm making a small Teapot server for Slack command bots, I'm goona push it to Github (yay Iceberg), if anyone is interested. - EduardoPadoan I just completed the @pharoproject Mooc the best investment I have ever made of my time. MAQBOOL Hey all - I've just finished the Mooc - thanks for an excellent course and a thouroughly interesting look at a new way to program :smile: Looking forward to starting to play with Pharo on some upcoming ideas I've had. - Tieryn As much as I thought I understand object-orientation, it is very clear NOW that without a truly useable Smalltalk, which Pharo is, it is impossible to really understand and exercise object-orientation. Thank you all soooo much. - Mike D. 06/12/2020 I finished the Pharo MOOC a few days ago. Thank you very much to Damien, Stephane, and Luc for their work on the material!

Impressed with the quality and content, and grateful that it is available and free. Many thanks! - Aryeh IMHO the videos were very well done. I would even say shockingly well doneâ¦ for a bunch of programmers who are supposed to be clueless about design - SeanDeNigris - 10/26/2017 The more I learning about @pharoproject the more I appreciate it's beauty and simplicity, finally, object-oriented programming is done right - MAQBOOL Mooc absolument remarquable.

Re: [Roassal - Spec ] How can I trigger the refresh of an inspector pane

by Pierre Misse Chanabier

Milton will probably correct me tomorrow, but in the meantime. You need to send the message #refresh to the RoassalPresenter. This will trigger the "script" that should have been defined. (At least that's how it has worked for me). For example: - my initialization: memorySpace := self instantiate: SpRoassalPresenter. memorySpace script: [ :canvas | "My creation/refresh code" ]. - my update: memorySpace refresh Pierre On 9/25/2022 4:01 PM, stephane ducasse wrote: > Hi > > I have a roassal pane in my inspector to display quadtrees. > I added the possibility to add a point to the inspected quadtree. > But the pane does not refresh > I have to do it by hand > and I would like to know how I can force the inspector to refresh >

Re: Pharo nanoseconds or clock ticks

Hi Kasper, There is `Smalltalk highResClock` that should be what youâre looking for. It's still not available in ARM64 builds, we need to define it using some handwritten assembly.
