[ANN] SmallHarbour ALPHA release
by laurent laffont Aug. 15, 2011

Aug. 15, 2011

Hi, We are pleased to announce the first version of SmallHarbour. SmallHarbour is a public fork of SeasideHosting, running on top of Pharo, Seaside and Cog - driven by Romain Verduci and Laurent Laffont for ESUG SummerTalk 2011. The main goals are: - people should be able to (easily) setup their own web application deployment platform - provide a public service for hosting web applications. - be able to setup a web application without Smalltalk knowledge in one click. Actually SmallHarbour support Pharo and Seaside, but we expect to support Iliad and AidaWeb framework soon. When an account is created, you can go in Home and click on "Create blog" to deploy a Pier image. More templates to come. The alpha public server is at: http://www.alpha.smallharbour.org. Feel free to upload images. BE CAREFUL: that may be deleted / lost without warning. Do not put sensible informations. To setup your own SmallHarbour, - read documentation at http://project.alpha.smallharbour.org/seaside/pier/Documentation - see screencast http://project.alpha.smallharbour.org/seaside/pier/blog/2011-08-11 Feedback is welcome. We still need to find bugs, fix them and learn. Romain will present SmallHarbour at ESUG. Thanks ESUG, Adrian and Netstyle for sharing code, Mariano for help, Claire and Patrick who are working on visual identity. Cheers, Laurent Laffont - @lolgzs <http://twitter.com/#!/lolgzs> Pharo Smalltalk Screencasts: http://www.pharocasts.com/ Blog: http://magaloma.blogspot.com/ Developer group: http://cara74.seasidehosting.st

PhD offer - Brest france
by Loic Lagadec Aug. 12, 2011

Aug. 12, 2011

Dear All, We are looking for a top candidate to join our research group as a PhD student. We have one opening in the area of Smalltalk-based Electronic Design Automation. Please could you broadcast to any interested student. The position is to be filled as soon as possible. The project starts on 1st october 2011. Kind Regards, LoIc Lagadec ARDyT - Fault tolerant dynamically reconfigurable architecture Position type: PhD Student Functional area: Brest, France Research theme: Smalltalk, Reconfigurable architecture, innovative toolkit design Project: ARDyT Contact: loic.lagadec(a)univ-brest.fr Title: Instrospection plan compliant EDA toolset Reconfigurable computing (eg. FPGAs) combines the flexibility of software with the high performances of hardware. This comes from the on-demand metamorphosis of the hardware - at runtime - by "loading" a new circuit on the reconfigurable fabric, while this technology also supports extreme optimizations, by allowing drastic changes to the datapath itself, in addition to tailoring the control flow as traditionaly met in microprocessors. While improving performances has been the key issue for years, very few efforts have been reported in debug automation. Debuging requires introspection capabilities, controlability and fast-changes support. HLS (High Level Synthesis) tools allow to compile high-level (C like) languages to netlist (electronic level), hence guarantee fast changes but controlability and instrospection are still very limited. In the scope of the ARDyT project (supported by the French National Research Agency), some evolutions will be carried out over a classical FPGA such as embedding extra resources that will offer some introspection capabilities. The PhD thesis will contribute to refactor/re-design an existing smalltalk based toolset in order to take into account these extra resources hence new paradigms such as to combine the computation plan and the instrospection plan of the proposed architecture. In addition, debug controllers will be made available on-demand within the netlist of the application. This offers new exciting perspectives, in a scope of domain space exploration (DSE). A model oriented approach will be considered to ensure the durability of the resulting software and of its design method. This PhD will be co-supervised by the Lab-STICC MOCS and IRISA.

[ANN] LatAm Squeaksource Mirror
by Johan Fabry Aug. 11, 2011

Aug. 11, 2011

Hi all, I'm happy to announce that we have a public, read-only Squeaksource mirror up and running at the Universidad de Chile. The URL is: http://www.dsal.cl/squeaksource/ TECHNICAL DETAILS BELOW. Feel free to broadcast this announcement! MOTIVATION: For us, Switzerland is a long way and the connection to Squeaksource has always been painfully slow. We've set up this mirror to help to address this, and I imagine that it will be of use not only for the Chileans but also other countries in latin america, which is why I am announcing it here. ITS TRANSPARENT: I've worked out a way to make the use of this mirror transparent when using Pharo 1.3: you just use monticello as always, and have a setting to redirect loads from Squeaksource to wherever you want. I have successfully loaded Moose and Seaside from the mirror using this package, so it should work for you. And I can tell you, it was blazingly fast: Seaside loaded in 5m45, and most of the time was spent compiling ... ;-) So try the mirror and the package out, send me your comments, we want to work on this to make Squeaksource a better experience for everybody. HOW TO USE from Pharo 1.3: - Get the redirection package from http://www.squeaksource.com/MonticelloRedirect - To load from the mirror instead of from Squeaksource, do-it of the following: MRManager redirectFrom: 'http://www.squeaksource.com/' to: 'http://www.dsal.cl/squeaksource/'. - To remove this redirection: MRManager removeFrom: 'http://www.squeaksource.com/'. - See comments of MRManager for more info. MRManager list can be useful at some times. - Only 2 classes, < 10 methods, not counting accessors. The trick is the use of MethodWrappers. - I did not test this in Squeak or other versions of Pharo. Feel free to try it out in your environment and send me patches if needed. - There is no UI, contributions are welcome!! DETAILS ON THE MIRROR - It's a full copy of Squeaksource, updated daily. - The mirror is read-only: if you want to make a commit you still have to do it in Squeaksource. This is to avoid all the complications of distributed writes. - Updates happen once a day, before midnight Chilean time. Updates take typically (up till now) 200 minutes (!), average download speed here is 200KB/s :-( - The Squeaksource team has been so kind as to provide a list of the packages that are in Squeaksource, refreshed daily and we pass this to wget (with some massaging of the data inbetween). - The Squeaksource list of packages is available here: http://scg.unibe.ch/download/SSProjectList/projectList.txt - The software that does the mirror is available here: https://github.com/vramiro/easy-wget-mirror MANY THANKS TO: - Daniel Galdames for doing the original mirroring tests - Victor Ramiro for taking Daniels' work and putting it in production - The Squeaksource team for providing the daily list of packages, especially Fabrizio Perin and Mircea Lungu - You for trying it out and telling us about it! ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile

My doubt is accessing of smalltalk's collections from provided low-level code. Another problem is how to prepare this low-level code, how to put it inside the method and so on. Something like "Hello World" for NativeBoost. > I don't remember an algorithm for multiplying matrices of arbitrary size. > I was taught it in university but it was long time ago :) Matrix algoritm is not that hard to find...wikipedia, you know. Generally speaking, if dot product solution will be demonstrated, I think, matrix multiplication will be easy. > ... and it converts it to utf8 encoding before pushing it to function. What function do you mean? One of smalltalk object's methods or something other?

> i'd like to know what you would like to know about things you don't > know about NativeBoost :) Well, ok, first thing I always like to see is examples of usage, you know. I mean not "packages which uses my package". I mean something like "Imagine, you want...some situation described.... You can do it with NativeBoost this way: ....code example...".

Writing an object graph into a no-sql database [WAS] Re: [Seaside] ESUG SummerTalk - Fuel, binary object serializer

Sorry to come back with this old post, but now I am interested ;) Right now, I have a requirement where I need to write a graph into a file. I am using Fuel for that. Each graph, has its own file. In the image side I just store the filename, When I need to load it it reads such file and materialize it with Fuel. I was thinking going a step forward and use a key/value (a.k.a no-sql) database. With Fuel, I can take a graph, and serialize directly into a ByteArray, hence I can take a graph to swap, I assign an ID, and and save it into the database. In the image side, I keep that ID. Then, when needed, I search it in the database and then after with that ByteArray found, I materialize it with Fuel. So...first question is, do you think that could be faster/better than directly writing into a file as I am doing now? Now, which are the available Pharo wrappers for no-sql databases that let me do that? I would appreciate any link or documentation about them. What do I need to use such databases from Pharo? FFI and a library installed in my machine? are there binaries for Mac OS? Thanks in advance, -- Mariano http://marianopeck.wordpress.com
