[Pharo-project] How important is ANSI Smalltalk / speeding up ASCII/Latin1/Unicode I/O
by Dave Mason July 23, 2009

July 23, 2009

I have been wondering about ways to speed up character-set conversions, and related I/O as mentioned in the recent email about MultiByteFileStream. However this change might break parts of the ANSI Smalltalk hierarchy - particularly around String. So my question is, how important is ANSI compatibility? Squeak? GNU Smalltalk? VW? VA? On a related question, how common is it to subclass String? Would it be a mess if it were its own little hierarchy of classes? ../Dave

[Pharo-project] The Pharo Toolset Guide (request)
by Esteban A. Maringolo July 23, 2009

July 23, 2009

Hi, As I told, I'm new to this squeak/pharo world, particulary in relation with its toolset. I'm developing, and by now I was using fileOut/fileIn to manage, save, version, etc my codebase. I would like to know how to create a Monticello repository to host my projects, how to create a package for them, etc. I know there are many versions around, and don't know which is the one in use in the latest Pharo core. Is there a "terse guide" to get a smalltalker coming from other smalltalk to understand the phylosophy behind the Pharo tools, and how to use them? Besides http://www.wiresong.ca/Monticello/UserManual/, is there any other resource I should be aware to learn the mentioned above? Best regards, Esteban A. Maringolo

[Pharo-project] Fwd: [Vm-dev] Fwd: Show stopper network bug on Windows

All, who interested in this, please continue this topic on VM-dev list. Because Andreas is maintainer of windoze VM, and no one knows better than he is of what is working or not and why. ---------- Forwarded message ---------- From: Andreas Raab <andreas.raab(a)gmx.de> Date: 2009/7/23 Subject: Re: [Vm-dev] Fwd: [Pharo-project] Show stopper network bug on Windows To: Squeak Virtual Machine Development Discussion <vm-dev(a)lists.squeakfoundation.org> Igor Stasenko wrote: > > Hello guys, those, who not subscribed to the Pharo list. > > I think you should read this: > Â http://code.google.com/p/pharo/issues/detail?id=961 > > since it seems there are some networking problems with Win32 VM. None of these are Windows VM issues. The problem referred to above is simply that someone was using a year-old 3.10.2 VM and tried to call IPv6 primitives (the debug log shows that clearly). The IPv6 prims are not available in these old VMs. The discussion below is similarly confused. The Windows VM does return fully qualified names if your network environment is set up properly. Usually, the domain name is set by DHCP, but you can set it manually in the advanced network settings (on XP it's under network, properties, TCP/IP, advanced, append dns suffixes; Vista will surely differ).

[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?

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
