Jenkins now live
by Chris Cunnington 01 Mar '12

01 Mar '12

http://76.74.255.163:8080/ Our Jenkins server is now live. I'll get it running behind squeakci.org. Then I'll configure the Workspace, zip files, and directories, so that users can cut an paste Smalltalk or Codex (the Mason build system DSL) into a window to have a Squeak 4.3 image execute, run tests, create a zipped deliverable, etc. I'm about four weeks ahead of schedule, as I said I'd get this done after Smalltalk Directions.

[Announce] S8 in the Concrete Jungle
by Elvio Fernandez 01 Mar '12

01 Mar '12

Hi! Alejandro Reimondo (Ale) will make a presentation about S8 platform and U8 service on Tuesday March 6, 2012 to NYC Smallltalk Developer’s group. http://www.nycsmalltalk.org/2012/01/10/s8-release-candidate-smalltalk-on-js/ There is a lot of topics to talk about..., the topic of most interest (to us) is to explain what we are doing with S8. A breaf description of our regional point of view about OT and Smalltalk, and our proposal of a modern formulation of development using Smalltalk will be the starting point of the presentation. The S8 platform was implemented to let us(smalltalkers) be responsible of our execution environments (as it was in the early days of smalltalk). That impose a change of attitude and the formulation/idea must be supported by tools and evidence/experience of others in the same field. As a demostration on how we can do that with S8, Ale will mention the platforms we have implemented for using the U8 service (designed to make worldwide social development with smalltalk http://u8.smalltalking.net ). On technical side, to mention where a person can start application development and self-learning using U8, he will describe the frameworks we have implemented on top of S8 (we all know the importance of frameworks) and the process we are using for development/testing of frameworks. The presentation is also open to the topics of interest of the audience. And Ale will be happy to respond questions about how to use S8 in diferent contexts of development. Some of the technical points that will be of interest are: - how to use our FFI framework? (make API calls, use native libraries and implement callbacks using S8; 100% smalltalk code) - how to do server side development? (NodeJS framework) - how to use your code from other smalltalks? - how to use javascript libraries? and (more important) how to write interfaces to existing libraries fast and minimize errors / testing points? - how to develop for Android and phones? - how to use cloud services? - how to work using U8? How to contact experts and people to do development of frameworks using the U8 service? - why we minimized the toolset at this stage? and what powerfull features of smalltalk we support today. - what is not implemented yet? and how to contribute? - ... In all the presentations and coding events we made here (in Buenos Aires) the time has been short for going deep in groups, and the presentation was important to get in touch with people that has interest in global development as it is used to be in this decade. So, if you are near NY on March,6 join us. If you can't attend there next week, please contact us at info(a)smalltalking.net and consider we have open the Betatesting site to start contributing and using U8 from now and we are doing one betaworks meeting per week to let people put their hands on the frameworks, tools and S8 platform, in small groups. ...If you can´t wait and want to start coding now/today, please visit the U8 page ( http://u8.smalltalking.net ) and register there to become a member of our community, to be in contact with people and companies interested in social development using Smalltalk. cheers, --------------- on behalf of Smalltalking Associationwww.smalltalking.net

I'm pretty new to squeak, please let me know if I should be looking for help elsewhere, (and where that would be :) TIA I'm trying to follow a OpenGL tutorial posted on YouTube by user sparaig. It's only 9 lines of code (Installer repository: 'http://source.squeak.org/FFI') install: 'FFI-Pools'; install: 'FFI-Kernel'; install: 'FFI-Tests'.

my principle (was: can this be done)

Bret encouraged people to "have a principle" and, it turns out, I seem to have one. "Ensure computers serve humans, not vice-versa."

reddit link for a squeak how-to please vote
by Lawson English 01 Mar '12

01 Mar '12

http://www.reddit.com/r/programming/comments/qcjo9/meta_howto_figuring_out_… Squeak is often used as a prototyping system for graduate students and professors, who are often notoriously bad at providing documentation. This video shows one of an infinite number of possible ways of using the Squeak IDE to figure something out: specifically, given a node in a graph built from the Connectors package, how does one figure out what that node is connected to? Please vote, thanks. L.
