Agile Artificial Intelligence book
by Alexandre Bergel Dec. 12, 2018

Dec. 12, 2018

Dear Colleagues and Friends, The first 6 chapters of Agile Artificial Intelligence are now stable. Now is a good time for reviewing them. The chapters are available online from: https://agileartificialintelligence.github.io/ You can also see that the structure of the book has evolved. I believe that the part are stable. Maybe content of Part II and Part III can still evolve. You can contribute to the chapters by simply making a pull-request. People who do so, (i) will have their name listed on the book website, (ii) will have their name in the printed version of the book, and (iii) I will be very happy to invite you for a beer next time we meet. Thanks to all of you who have pushed the book and sent encouragements. The community deserves your effort. Kind regards, Alexandre

Unable to compile myself Pharo
by Garreau, Alexandre Dec. 11, 2018

Dec. 11, 2018

I need Pharo soon for my studies, and since itâs not packaged for debian (how sad for something requiring bootstraping hence binaries :/) I wanted to compile it, but (please tell me what additional informations I could give you, Iâm under Debian GNU/Linux 32bits for now) since then: galex-713@portable:~/doc/comp/src/pharo$ make ./pharo bootstrapImage.image ./bootstrap/scripts/bootstrap.st --ARCH=32 --BUILD_NUMBER=1 --quit pthread_setschedparam failed: Operation not permitted This VM uses a separate heartbeat thread to update its internal clock and handle events. For best operation, this thread should run at a higher priority, however the VM was unable to change the priority. The effect is that heavily loaded systems may experience some latency issues. If this occurs, please create the appropriate configuration file in /etc/security/limits.d/ as shown below: cat <<END | sudo tee /etc/security/limits.d/pharo.conf * hard rtprio 2 * soft rtprio 2 END and report to the pharo mailing list whether this improves behaviour. You will need to log out and log back in for the limits to take effect.

Testing User Agent from Zinc
by horrido Dec. 10, 2018

Dec. 10, 2018

Is there any way I can check the user agent string from Zinc or Teapot so that I can determine whether the user is on a mobile device? I need to modify the HTML accordingly and it's really, really messy trying to do this with JavaScript (navigator.userAgent) and conditionally inserting innerHTML. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] OpenGL resources?
by Esteban Lorenzano Dec. 7, 2018

Dec. 7, 2018

Hi, wellâ¦ there is an (or several) OpenGL packages. I would say is a perfect environment because you do not have the compile cycle, but you already know that :) Iâd recommend starting here: https://github.com/ronsaldo/uffi-opengl <https://github.com/ronsaldo/uffi-opengl> And in general, anything Ronie does is âgraphic-heavyâ. I would take one of his projects/demos to learn how to use it.

OpenGL resources?
by Todd Blanchard Dec. 7, 2018

Dec. 7, 2018

Hi, I need to learn OpenGL for my job and was wondering if any of the OpenGL experts could comment on Pharo's OpenGL integration and its suitability for a learning environment. Are there any particular packages I should look at that are heavily OpenGL oriented that would make a good base for learning? Thanks

Fwd: Announcing Repl.it Multiplayer
by Santiago Bragagnolo Dec. 7, 2018

Would this be interesting to have in pharo?? What do you think? ---------- Forwarded message --------- From: Amjad from Repl.it <contact(a)repl.it> Date: jue., 6 de dic. de 2018 21:55 Subject: Announcing Repl.it Multiplayer To: <santiagobragagnolo(a)gmail.com> The official release of Repl.it Multiplayer, the collaborative coding experience. [image: Repl.it Logo] <http://url1361.repl.it/wf/click?upn=LLQySNMYKcsdrD3Xpw6uy0-2F0rOvSNWPLVoxcc…> Hey Santiago, Professional programmers all know that software development is a fundamentally social experience. But coding remains a single-player experience by default â today, we're changing this! As part of our mission to make computing more accessible, we believe connecting coders, learners, and teachers together in real time, in the development environment, is a big piece of the puzzle. That's why we're proud to announce *Multiplayer*. Multiplayer lets you code with friends in the same editor, execute programs in the same interpreter, interact with the same terminal, chat in the IDE, edit files and share the same system resources, and ship applications from the same interface! We've redesigned every part of our infrastructure to work in multiplayer mode -- from the filesystem to the interpreter.

Re: [Pharo-users] Pharo 7 Monticello browser and github repositories

Your feedback as a fresh Iceberg user would be useful. Sorry I don't have any links handy, but it would be interesting to see what you can work out intuitively. One thing though, if you are using Windows you'll need to "Use custom SSH keys..." (if you are using ssh based protocol) cheers -ben
