[ANN] LatAm Squeaksource Mirror

by Johan Fabry

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 know very little about NativeBoost. I'm very interested in its implementation, but would like *some* examples of usage. Regards, -Martin
