Hello, After a long wait... finally: http://www.youtube.com/user/esugboard#grid/user/843D1D545F9F52B6 This now has: - Extensive, great two part PetitParser Tutorial by Doru (3 hours) http://www.youtube.com/watch?v=vgiJG3Vd6KU If you ever wanted to write a Parser, this will give you a very understandable, step-by-step introduction. - Enhancing SqueakNOS. http://www.youtube.com/watch?v=u9RUmIY2Sz8 Crazy, these Argentinians... - NativeBoost: http://www.youtube.com/watch?v=Bd6mz6F167s Generate Binary code from the image. And a *very* fast FFI as an example. Guido and Javier of the SqueakNOS video above are right now busy here in Lille building something *very* interesting with NativeBoost... - FFI, an introduction by Igor: http://www.youtube.com/watch?v=fU8XRCO7MUU What is FFI and how do we use it? - and the first part of "A little Journey in a Virtual Machine" http://www.youtube.com/watch?v=FJQmjhOvjUs This has 5 (!) parts and together with the FFI presentation, this allows you to experience the very first lecture ever given by Igor Stasenko. More to come... but this already might keep interested people busy for some enternaining evenings :-) We will post all the rest step by step. The ESUG Youtube account has more stuff posted already, e.g. the talks of this years IWST Workshop and some talks of ESUG2011, and the classic talk of Doru from ESUG 2008 showing how (not) to give ESUG talks.

OpenDBX + PostgreSQL + MacOS ? [WAS] Re: [ANN] Pharo Glorp port release

I'm trying to > connect to PostgreSQL on my Mac, if that matters > Well, that's the most complicated part and drawback of OpenDBXDriver: that you need both, OpenDBX library and the database client library. And there is even one more problem: SqueakVM FFI has problem with 64 bits... So...you need the following: - Install OpenDBX. You can get the binaries or compile it. - Install PostgreSQL database client 32 bits. The most documentation you can get is: http://dbxtalk.smallworks.com.ar/Compiling%20and%20installing%20OpenDBX http://dbxtalk.smallworks.com.ar/Compiling%20for%20different%20backends What you can find there was mostly written by me, that means, there are the backends that I have compiled. So for example, you won't find how to do it with PostgreSQL in Mac because I never did it. Maybe someone did it and can help you. I guess it should be similar to doing it in Linux. Finally, notice that for Windows you can download OpenDBX .dll, for Linux .rpm .deb but for Mac there isn't any binary because we don't know how to do it. Finally, notice that with our refactor of Glorp, you are able to use Glorp with the Smalltalk native client (no usage of openDBX). For production env I suggest using OpenDBX, but for a simple prototype or test, you can use the native driver instead.

Has the JTALK presentation been recorded? Where can I find it? I've found the slides, but not the talk itself. Thanks!

long ago morphic demos
by David West Sept. 14, 2011

Sept. 14, 2011

the early distributions of squeak included a project with several morphic demos: clock, racetrack, lens, scrolling text through a complicated space, etc. Are these still available somewhere? under what name? Or, do I have to load and old version and file-out? thanks davew

With the Fabrik demo, the text-flow and things like that. These demos where not created by code but contructed (by a human) and just in the image as Projects.

Bye, bye Jtalk... Hello Amber!
by Nicolas Petton Sept. 14, 2011

Sept. 14, 2011

As some of you may know there is a new Smalltalk in town - and up until today it was called Jtalk. After a furious three week development period after the ESUG 2011 conference (where Jtalk raised some eyebrows) we are now making a first release humbly numbered 0.9. We are also taking the opportunity to pick a slicker name for Jtalk - Amber! New website is at: http://www.amber-lang.net So, why would you take a look at Amber? In our opinion Amber is perfectly positioned for the HTML5 onslaught and the explosion of all-things-javascript like for example Nodejs. It is a Smalltalk that plays well with others and can seamlessly use Javascript libraries. At the same time Amber feels like a *real* Smalltalk, the environment is all there including Workspace, Transcript, Browser, senders/implementors/references to class, TestRunner, Inspectors, code editing with syntax coloring and a Debugger. There is no image, but all compilation is incremental. Below follows a summary of the massive changes since ESUG that triggered us to make a first release. We hope you join us in developing Amber and having fun! There is already work being made in using Amber on top of Java using Rhino, using Amber for making games and lots more. Fork at github, join in #amber-lang on freenode and hop onto the mailing list. regards, Nicolas & Göran (and thanks to Laurent, David, Bernat, Stefan, Raimon, Alexandre, Dale, Juraj, Ken, Pavel and everyone else that have been involved) --------------------------------------- Language, compiler and runtime - New 100x faster parser built using PEGjs instead of the old parser built using PetitParser. - New much faster ChunkParser implementation in handwritten Amber instead of using PetitParser. - Improved parsing error report with quoted source code plus marker pinpointing parsing error. - Removed PetitParser since it is no longer needed by Amber itself. - Added compiler optimizations in the form of speculative inlining of specific messages and control structures. - Added support for dynamic Arrays, just like in Squeak/Pharo. - Added support for similar dynamic Dictionaries, not seen in other Smalltalks. - Added & and | as allowed binary selectors and implemented them in Boolean. - Added a Set implementation. - Added basic support for Packages, dependency management coming soon. ...and various extensions, enhancements and bug fixes to the library classes. Development environment - A working Debugger with integrated inspector, proceed etc. - A structure with multiple different Amber environments in different directories. - A working amberc command line compiler including a Makefile for recompiling the whole Amber. - Enabled TestRunner in the IDE for running unit tests based on SUnit. - Added "File in" button in Workspace to easily paste and filein source code in chunk format in the IDE. - Added "Rename package" and "Remove package" buttons to browser that use the new Package model. - Added a standalone webDAV server in Amber so that it is simpler to get up and running and able to commit code locally. Example code and ports - Ported ProfStef interactive tutorial, available on Amber homepage (www.amber-lang.net/learn.html) but also in examples directory. - Included the ESUG presentation as an example also in the examples directory. - Several new examples running on Node.js and webOS included, all with Makefiles. Various other things - Issue tracker on github now used as primary source, closed a bunch of reported issues. - Wiki pages on github with information on how to port code from other Smalltalks, lists of articles, tutorials, roadmap and more. -- Nicolas Petton http://www.nicolas-petton.fr
