funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

Package browser?
by Rob Vens June 28, 2013

June 28, 2013

I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. Should I still use categories? If I create a package in Monticello browser I am not able to add classes or anything (not as far as I could see). Just starting out using Pharo, so apologies if these questions are already answered elsewhere.

Actors library
by Alex Schenkman Jan. 24, 2012

Jan. 24, 2012

Hi list, Is there an Actors library already available in Pharo? The part I'm interested in is the asynchronous message passing. If it has been done already, why not reuse? Thanks in advance!

Node.js seems to be a wrapper around a C-Library that provided async IO for all platforms. Wouldn't it be possible to provide binding for the C part of Node-JS and use that for async/Event based IO?

Serializing to/from Json
by Larry White Aug. 30, 2011

Aug. 30, 2011

Hi, I'm hoping to use CouchDB for storage on a seaside application. It would be lovely if I didn't have to serialize/de-serialize by hand to json for all my persistent objects, and could use instead something like a smalltalk version of Google's Gson library. Is there anything like that? I've tried the JSON library bundled with SCouchDB and it seems to automatically handle simple objects (eg, where the inst vars reference Strings or Numbers), but not handle more complex objects. Also, I haven't seen anything that de-serializes from json. Thanks much! Larry

I have no experience using with the Mac. I do not load the latestVersion but the stable version of FFI, which is I think 1.3. So after loading the Configuration from the Metacello Repo I just do ConfigurationOfFFI load in a workspace. The problems I had with it were using it on a 64bit os and a 32 bit vm. I needed to get the 32 bit versions of the libraries I wanted to access loaded and accessible on my system.

[ANN] LatAm Squeaksource Mirror online again
by Johan Fabry Aug. 25, 2011

Aug. 25, 2011

Hi all, I'm happy to announce that the Latin American public, read-only Squeaksource mirror is again up and running. (We are bringing the contents up to date right now, it should be competely up-to-date in about 5 hours ...) The URL is: http://www.dsal.cl/squeaksource/ Note that you can use this mirror *in a completely transparent fashion*. We have worked out a solution to the privacy issues raised by the first iteration of our mirror. I would like to emphasize that private data has never been present on the mirror, only the name of private projects was accessible. TECHNICAL DETAILS BELOW. Please redistribute this announcement! (below is mainly a repeat of the body of my previous mail) 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 :-( - Lukas Renggli pointed out that the Squeaksource sitemap file provides a list of projects. We pass this to wget (with some massaging of the data inbetween). - 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 helping us, especially Fabrizio Perin and Mircea Lungu - Lukas Renggli for pointing out the issues with the previous version and providing an alternative. - 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

Fwd: [Pharo-project] [ANN] OpenDBXDriver Release - DBXTalk Release Step 1
by Mariano Martinez Peck Aug. 25, 2011

Aug. 25, 2011

---------- Forwarded message ---------- From: Guillermo Polito <guillermopolito(a)gmail.com> Date: Wed, Aug 24, 2011 at 1:19 PM Subject: [Pharo-project] [ANN] OpenDBXDriver Release - DBXTalk Release Step 1 To: Pharo Development <Pharo-project(a)lists.gforge.inria.fr> Hi folks!! We are proud to make our first release of OpenDBXDriver -1.0 version-, formerly known as SqueakDBX. Now the project involves much more than just a database driver. This whole new project is called DBXTalk and OpenDBXDriver is just one of the sub-projects. There are several changes between this version and the last one of SqueakDBX, but most of them is about infrastructure: test were moved to a separate package, platform packages and backend classes were renamed, all "SqueakDBX" was replaced with its new name. To install it: Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfOpenDBXDriver'; load. (((Smalltalk globals at: #ConfigurationOfOpenDBXDriver) perform: #project) perform: #version: with: #stable) load. We have also created a new repository for all the code: http://www.squeaksource.com/DBXTalk The issue tracker is in: http://code.google.com/p/dbxtalk/issues/list Thanks to Natacha Perrin we have a new DBXTalk logo that you can see in: http://imageshack.us/photo/my-images/37/dbxtalk46.png The license of the logo is Creative Commons. We have also started a Pharo By Example chapter. So far we are writing about DBXTalk, but soon we will do about Glorp. We attach a draft of it while it is integrated into the main git repository of the book. Just in case here is the git repo fork: https://github.com/guillep/PharoByExample-english. Just to let you know, we have already ported the last VW release of Glorp to Pharo and we have it already working MySQL, PostgreSQL, Oracle and Sqlite3. We are closing some last problems and we will soon make the first release. We want to thanks Alan Night for all his help and his reviews :). 4 persons of the team are present at ESUG right now and we are going to give a talk on Friday. We will upload then the slides. Finally, we would like to thanks ESUG for the sponsorship through this ESUG SummerTalk. Thanks! Guille, Mariano, Esteban, Santiago, Gise -- Mariano http://marianopeck.wordpress.com

Memories about an ESUG talk: Smalltalk's Image Problem
by Offray Vladimir Luna CÃ¡rdenas Aug. 19, 2011

Aug. 19, 2011

HI all, I was making a talk here in Colombia trying to invite people to conform a Smalltalk study group. I was showing them Pier and Seaside as "selling points" for making a project and there is some initial interest. The typical questions about: * If Smalltalk is so good, why is not widely known ? * Which famous/big project is made with Smalltalk ? where in place. I think that Pier, Seaside, Etoys, Scratch, DrGeo, Croquet, are really good projects to motivate people towards learning Smmalltalk, but they're kind of "niche" projects (I have no problem with that), but searching for information about who to solve these questions I found this talk on ESUG 2009: http://www.esug.org/Conferences/2009/Current+List+of+Talks/Smalltalk%27s+Im… So I wonder if anyone has the memories/slides of this talk and, of course, what community thinks about these questions. Thanks, Offray
