[ANN] Pharo Glorp port release
by Guillermo Polito Oct. 13, 2011

Oct. 13, 2011

Hi! We are reaaaaally happy to announce (at last) a very very stable release of the new Glorp port :D. We've done a lot to achieve the following results with Glorp: OpenDBX Oracle: - 7 errors related to Blobs, which are not supported by opendbx. - 1 failure related to timestamp cast (and I don't understand the test intention yet :P) OpenDBX MySql: - 100% green tests :D OpenDBX PostgreSQL: - 7 errors and 1 failure related to Blobs, which are not supported by opendbx (again). OpenDBX SQLite: - 6 failures related to large objects, which are not supported by opendbx (again again).. 2 (expected) failures related to times & dates. Native PostgresV2 Driver: - 2 failures with blobs So far, some FAQs: *¿What is the difference between this port and the old one?* Almost 4 years of work of the VW team with tons of bugfixing (see the last 4 years release notes from Glorp for more detail :P) *¿How can I load it?* If you want to load Glorp + OpenDBX, you can try the following: *Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfGlorpDBX'; load. (((Smalltalk at: #ConfigurationOfGlorpDBX) perform: #project) perform: #version: with: #stable) load* Also, you can try loading only Glorp (maybe because you want to integrate it with your own database driver): Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfGlorp'; load. (((Smalltalk at: #ConfigurationOfGlorp) perform: #project) perform: #version: with: #stable) load *¿How did we test it?* We've tested it in Pharo 1.2 and Pharo 1.3 + Jenkins CogVms. *¿What's coming next?* *We are working for your happiness (?).* Hehe, our next step is to release the DBXMagritte project, which aims to allow people working in the Software business to create easy CRUD -the same scaffolding idea from RoR for example- including some of the following features: - (create a class model + magritte descriptions) from a database schema - [if you already have a descripted class model] use magritte descriptions to create a database schema - use magritte descriptions to create glorp mappings And then, you can use the same descriptions for your Seaside app, or in every magritte-friend framework you like ;) So, thanks again to ESUG for sponsoring the project :). Guillermo, Santiago, Gisela, Mariano, Esteban and Diogenes

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.

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.
