[Pharo-project] 'primitive has failed' in MultiByteFileStream while running update
by Boris Popov July 22, 2009

July 22, 2009

I'm new to Pharo, so one of the first things I tried was to go System->Software update, which results in the attached error after a while, Pharo0.1 Latest update: #10379 Squeak VM 3.11.3 (beta) from Jul 10 2009 Also, why is debug.log using Mac EOL convention on a Windows machine?

[Pharo-project] Producing a new core

Hi, it's been quite some time (relatively to Pharo speed) that no core has been produced. Could you please release an image? Thank you -- Damien Cassou http://damiencassou.seasidehosting.st "Lambdas are relegated to relative obscurity until Java makes them popular by not having them." James Iry

[Pharo-project] Who are you?
by Alexandre Bergel July 22, 2009

July 22, 2009

Dear all, 284 people are subscribed to this mailing list. It is a bit hard to deduce how many users of Pharo there are, but the number of subscriptions gives a number at least. How many companies are using Pharo? Without thinking too much, I know there are Netstyle.ch and Pinesoft. Are there more? I am preparing an academic presentation and having such figure will be great. Kind regards, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

John do you know if the primitives mentioned by nicolas are integrated in the mac VM. David Lewis integrated them apparently in VMmaker http://bugs.squeak.org/view.php?id=7368 http://bugs.squeak.org/view.php?id=7260 Stef

[Pharo-project] Halo lost in linux and others quirks
by jdinunci＠uc.edu.ve July 22, 2009

July 22, 2009

Hello, I'm new to smalltalk, I've been trying squeak for some time, and recently I discovered pharo, so I downloaded the files and started to play with it. The problems: *) Halos behave inconsistently: I can only activate halos in the world menus. If I middle-click in the workspace, the preference browser or any other window, they don't appear. *) Preference Browser -> Keyboard: If I deactivate duplicateAllControlAndAltKeys and duplicateControlAndAltKeys, no matter the state of swapControlAltKeys, actions like copy are always invoked by the alt key. *) If I use the window menu -> window color and *drag* the pointer over the palette, the system slows down and the mouse is captured by the palette for several seconds (the more time you drag, the more time you need to regain control). Where I'm tenting: @ work: Intel Core2 Duo, 2GB RAM, Ubuntu 9.10 64 bits @ home: Intel, 512MB RAM, Ubuntu 9.10 32 bits What I'm testing: set #1: pharo-vm-0.15.1b-linux, pharo0.1-10373web09.07.2.zip set #2: pharo-vm-0.15.1b-linux, pharo0.1-10379dev09.07.3.zip set #3: exupery 0.15-linux, pharo0.1-10373web09.07.2.zip set #4: exupery 0.15-linux, pharo0.1-10379dev09.07.3.zip all sets with SqueakV39-sources.zip In all sets, both machines, the problems were the same. I've been playing with squeak 3.9 installed from the official ubuntu repository in both machines and it runs fine. I tried using that interpreter with the pharo images and it couldn't read the images due to version mismatch (6502 vs. 6504). I' tried to compile the last squeak but I didn't had all dependencies at hand, and it was too late. Thanks -- Ing. JosÃ© Dinuncio Unidad de Redes TelemÃ¡ticas Universidad de Carabobo

[Pharo-project] [ANN] Algernon now available in Pharo
by Esteban Lorenzano July 22, 2009

July 22, 2009

Hi, I uploaded a new version of Algernon, now working with Pharo. The changes I introduced were: -changed the updating system: now it is automatic, but just when Algernon is shown (this will make a little bit slower the showing of Algernon, but preserves you from need to press cmd+r to refresh the system -who after all, everybody I know does every time-). -using #beginsWith: instead deprecated #startsWith: -using #fileOutCategory: instead non-existing #fileOutCategory:asHtml: You will need latest changes of Pharo (Stef fix to TextMorph), and execute this script to have Algernon on your system: ScriptLoader new installingUniverse. "In case you don't have already Universes installed" Installer universe addPackage: 'Algernon'; answer: '*' with: false; install. Installer ss project: 'Algernon'; install: 'Algernon'. Installer wiresong project: 'ob'; install: 'OB-Algernon'. Algernon open. Cheers, Esteban

[Pharo-project] Why Pharo?
by Esteban A. Maringolo July 22, 2009

July 22, 2009

Hello, Mariano's post spurred me to write my reasons of "why to use it", so I started this post. >>After many hesitations (I was reluctant to use Squeak) I decided to >>use Pharo for it and not Dolphin (my favorite Smalltalk), because of >>several reasons. >would be nice to know them hehe >sorry...in another thread. - It's mainly about getting mainstream, and not willing to develop everything from scratch once and again. - At work we've developed everything by our own on VSE/Dolphin, so every time we wanted to do something, we had to build it by ourselves (most of it). We even had a Magritte like framework (years before Magritte existed), persistence, reporting, etc. Now some of them, are very mature frameworks. But I can't borrow any of them for personal use ;-) and don't want to spend a year rewriting the frameworks I've created, contributed to or used at work. - Because what I want to build is going to be web based (and I hope to get it mobile to), anything that runs on linux is good to be considered as a server solution. - So I wanted a rich class library/frameworks, in order to be able to focus on the business logic I want to build. - I wanted to have the latest versions of such frameworks, even when it's getting easier to port them (I did port Swazoo and Seaside in the past), I'm not in the mood to do it now (yes, I'm getting lazy). - Because Dolphin future is uncertain yet, DNG seems to be the next-generation VM/Smalltalk, but I can't wait until it's ready, the conditions clear ($$$) and have the above mentioned points included. - Because I like where Pharo is going to, or seems to be going. I like its mission and how its being managed (releases, issues, patches,tests). It's a solid foundation for any reliable project. - Because nothing really new has come from other really good smalltalks like VAST/Dolphin/VW, everything is getting ported, and eventually a contribution gets back to the source. I see GLASS as an "extension" of Pharo/Squeak, because it was made very compatible, and the edges in contact work very close to each other (GLASS is useless if outdated in relation with Pharo/Squeak). - Because after all, Pharo is also Smalltalk. And I rather choose it before going to other also good stuff (like Rails), or not so good as PHP/Java/DotNet) - I want to focus on the business I'm trying to solve, and forget about everything mentioned above. The only thing that keeps me remembering the stuff above, is I'm still not comfortable as I am with Dolphin, not just because of habit. Dolphin's IDE is really neat, quick, consistent, gets the stuff done and then gets out of your way. You have to use it and do some real work to understand what I'm talking about. But I'm pretty confident Pharo will achieve such level of maturity in the not so far future. I hope it clears my reasoning behind choosing Pharo. Best regards, -- Esteban
