Smalltalk Virtual Machine, StVM
by askoh May 14, 2014

May 14, 2014

There is a trend of making languages to run on Java Virtual Machine. But it still cannot run Smalltalk like Smalltalk on Smalltalk VM. Is it a possible goal? How about running Java on the StVM so that Java can have the live environment and debugging capabilities like in full blown Smalltalk? How about doing the same for Python, Ruby, Lisp, ObjC, C#, etc? Thanks in advanced for all you thoughts.

geometric framework
by Natalia Tymchuk May 14, 2014

May 14, 2014

Hello. I want to do visualization on Roassal and I need the geometric shapes and their properties, for example: build circle on 3 points; find mid perpendicular. Can you tell me does some framework exist or no? Thank you. Best regards, Natalia.

Serial port support on Pharo (2 or 3)
by Goubier Thierry May 14, 2014

May 14, 2014

Hi all, has anybody success using serial ports with Pharo on Mac or Linux? We're having reports of lack of success, including lack of success in recompiling a Pharo VM with a correct serial port access (a few months ago), where the same approach was sucessfull with a squeak VM.

Github & Pharo.org
by phil＠highoctane.be May 13, 2014

Am I blind or am I having a hard time spotting our stuff on GitHub from Pharo.org as well as some other properties that help us be visible? Meaning: https://github.com/orgs/pharo-project/ https://github.com/SquareBracketAssociates are very important places and aren't mentioned much. As are: https://github.com/tide-framework if someone wants to use Marina so use the Pharo power... Maybe can we add these and http://en.wikipedia.org/wiki/Pharo as well (as we bothered updating the page...) Also, in http://pharo.org/get-involved we sent people directly to the Fogbugz thing. We should mention this Penelope monkey as well: http://bugs.pharo.org/ Also, in documentation, people are doing webapps, so we need to add "Dynamic Web Development with Seaside" to http://pharo.org/documentation http://book.seaside.st/book And, we also must also add this gorgeous http://spec.st/ and Sebastian's Mapless supernice site as well. I do not have access to the CMS, so please some kind soul, do it :-) [or tell me how] Phil

developing games in Pharo
by Ralph Boland May 13, 2014

May 13, 2014

I was recently approached to develop a children's educational computer game version of a real (wood etc.) game (looks like a pretty good game). I said I would only be interested if I could do the first implementation in Smalltalk (Squeak or Pharo). But if I develop this game in Smalltalk what am I dealing with in terms of releasing this product to a customer (over the Internet). 1) I know I have to build a suitable executable but I have never done this. I have only written Smalltalk code that I then use. So how do I build such an image and how big is it (assume code for game is small (say 3000 lines of code)). 2) How do I get the virtual image on the customer's machine. Keep in mind the customer is someone somewhere on the Internet who probably knows little about how to install Smalltalk or anything else. I am assuming here that installing the game and installing the VM are two different tasks. Is there a way to make this a single task? 3) So far I am assuming the target machine is Linux/Windows/Mac on a Desktop/Laptop. But can Smalltalk be run on any of the IPad/Notebook/etc out there? These machines represent a larger game market I believe. 4) Assuming I can arrange for my computer game (if I write it) to be installed are there memory/cpu usage issues that I need to worry about (the game itself will use a minimal of memory/cpu except for graphics which also is pretty reasonable). I am thinking here of IPads etc. For Desktops/Laptops there should be no problem. Download time and subsequent storage space is also a concern; remember the device is probably used for lots of other things so the amount of space allocated for games may be small compared to the space on the machine? 5) Sorry for the redundancy if these questions have been asked before (which I am sure they have). Thanks for any feedback; I am sure others are interested in this question too. Ralph Boland

Instead of making the initial framebuffer large enough, I changed the code in NBGLFrameBuffer>>extent: to reattach all attached Renderbuffers. ( I don't know if this is a driver issue or if it is a failure in NBOpenGL) Again, someone can tell me where (OS, graphic-card) Roassal 3D runs out of the box? And even now, that I solved this issue and all(many) Roassal examples are working, The R 3D IDE still only shows a black screen. And I still don't know what this is supposed to be, any tutorial screenshot or video, showing what R3D IDE is? Nicolai
