- what are the different VM built by the Pharo project continuous
integration server
- how to get the platform sources from Gitorious
- how to generate the interpreter sources using ConfigurationOfCogVM
- build the VM
- run and debug it with gdb and XCode
- what Slang is and how to change it for debugging purposes

Enjoy it here: http://www.pharocasts.com/2011/04/debug-cog-vm.html

Hi guys. I think there is a mistake..."expert"??? No....I am FAR from being an expert. I am just a newbie like you but that I try to share the minimum I learn.
BTW, the video has a couple of mistakes I did that I want to share just in case:

1) I downloaded git in an ugly directory (inside the build of another git repository) and then I don't know why there was an error and I couldn't download git sources again. So, I needed to stay with the ugly and confusing directory.

2) When I debugged with XCode you could see there were a lot of '??' in the debugger. This was wrong and it was because of a compiler flag in the Mac builds. This was fixed a couple of days ago, what we were still using an old version

3) when we put a flag in the method lookup for the #dnu it didn't work because (I think) of the black magic that happens when executing things from the workspace. If I would have evaluated the same code but from a method, it should have worked

BTW, How can I have such an ugly voice? heheh

Cheers

Mariano

You are not alone. Most people usually don't like how they sound.
But you are not TV narrator/reporter to care about that. :)

You did a great job Mariano & Laurent. Thanks!

To: [hidden email]

My apologies for the short lead time, but I need a person that is very
conversant with Squeak-Seaside-Pharo-Pier-GLASS plus an interest and
ability to quickly learn and mentor others in web-mobile languages and
tools. Will be working with English speakers, so facility in that
language is essential.

The person must be able to be in New Mexico, US, from May 23 to July 29.

You will be working 6-8 hours a day, Monday through Thursday - teaching,
mentoring, developing projects (list below) and overseeing my software
Studio when I am in London Jun 4-19.

Compensation:

Approximately $10K USD plus health benefits for the two-months. If you
like the work and are good at it, the position can be converted to a
one-year, renewable annually, as a visiting professor (at least a
Masters degree is required). The annual salary will be approximated
$60K USD plus benefits.

An ownership interest in the products being developed is also available
- as a supplement to the academic salary.

Applications we will be working on, priority order -- technology:
1) iPad app for the Bradbury Museum at Los Alamos National Labs --
XCode - cocoa based framework
2) an outcomes assessment app for Highlands University -- Web ecology
(HTML,
CSS, PHP, MySQL, Javascript)
3) itsYourRep - an achievement profile / portfolio Web App - very
similar to #2 -- GLASS
4) confirmOwnership - for paying client, tracks ownership interests
in investments, etc. -- Seaside or GLASS
5) ambientAgile -- an app using cameras and projectors to create a
distributed 'agile wall' -- not sure, start with Squeak-Seaside
6) Web-based subset of Behavior! Seaside or GLASS
7) Infrastructure for Software Design Studios - content management
plus Web presence - Seaside / Pier / GLASS

I must find a person very quickly, so if you are interested, please
email me and we can arrange a phone call to discuss the opportunity.
