[JOB] We are Looking for a Pharo Engineer
by Marcus Denker June 7, 2010

June 7, 2010

Hello, INRIA RMOD is looking for a full-time engineer for helping with Pharo development. As researchers, we need a really great system to explore new ideas with. The job of the engineer is to help us by improving the infrastructure we use for our work. What this of course means is that it's kind of a cool job: work in a research lab, but no paper writing, no teaching, no administration. In addition: - live in France (one hour from Paris, 1h20 from London, 35 min from Brussels) - try a lot of good beers (our office is just 10km from the border to Belgium) - french food - code all the day in Smalltalk and a bit of C Apparently from what the DHR services told us, the salary will depend on years of expertise and diplomas. We can think that 2700 Euros (before final taxes) should be a good working number for a candidate of the experience we are looking for. In France the employer pays already social security and pension. So the salary already includes lots (and lots) of deductions compared to e.g. a german brutto salary. Lille is an active city but not expensive (lot of students...), centrally located with good connections by train to everywhere (including CDG and Brussels airports). The job will to continue making Pharo better - better tools - better network support - better compiler infrastructure - improve the VM - help with day-to-day bug fixing and constant improvement Therefore we are looking for a candidate with some years of Smalltalk (possible Pharo/Squeak) background. Duration: 30 months Starting date: October 2010 Location: Lille (no remote job possible) Official Job Description and Application via: http://bit.ly/dyhdba Deadline: 15 July 2010 More about INRIA Lille: http://www.inria.fr/lille/ INRIA in General: http://www.inria.fr Engineers at INRIA: http://www.inria.fr/travailler/metiers/accompagnement/dev_applications.en.h… Lille: http://en.wikipedia.org/wiki/Lille http://www.mairie-lille.fr/en http://wikitravel.org/en/Lille Do not hesitate to contact us for more information.

Pharocasts: GUI - Proportional layout
by laurent laffont June 6, 2010

June 6, 2010

Hi, here's the screencast based on the GUI layout section of the Pharo book. http://pharocasts.blogspot.com/2010/06/proportional-layout.html I found a better (but not perfect) tool to edit subtitles on Linux: Jubler http://www.jubler.org/ , it's cross-platform. See http://www.my-guides.net/en/content/view/105/26/ Cheers, Laurent Laffont http://pharocasts.blogspot.com/ http://magaloma.blogspot.com/

A Day At The Beach
by Sven Van Caekenberghe June 5, 2010

June 5, 2010

Hi, Back in 2003, when Seaside was still very young, I wrote a short article about our initial exposure to Seaside. Recently, I went back to Seaside (and Pharo), pleasantly surprised by the immense progress made since then. So I decided to update the article, the code and the screenshots. It is targeted at people new to Seaside and Smalltalk. http://homepage.mac.com/svc/ADayAtTheBeach The examples are now also live. http://caretaker.wolf359.be:8080/ To all those who worked on Seaside/Squeak/Pharo since then: thank you ! You have much to be proud of. BTW, consider this my 'hello' message to this list, I am new. As far as I am concerned, Pharo rocks.

Debugging "Error: Could not access..."
by Geert Claes June 3, 2010

June 3, 2010

I am trying to use the debugger to find our why I get: "Error: Could not access http://www.squeaksource.com/Pharo" via an HTTP proxy server with authentication. I have successfully saved the network settings and from what I can tell the HTTPSocket has the correct HTTPProxyServer/Port and seems to have something in HTTPProxyCredentials so how do I find out why I get the Could not access? http://n4.nabble.com/file/n2228445/Proxy_Authentication_Settings.png http://n4.nabble.com/file/n2228445/Error_-_Could_Not_Access.png -- View this message in context: http://forum.world.st/Debugging-Error-Could-not-access-tp2228445p2228445.ht… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Fwd: [squeak-dev] Re: Using WebClient

I will continue with the multipart stuff, because this may become a payed work for a local customer. Indeed I could do the job with other tools but in most of cases that means install a gazillion of different pieces of software of third parts that are complex to make work. I prefer to develop my own solution, even with a bit more of work, but completeley Smalltalk. Then I can deploy on the customer a self containded service that I can extend as the customer need. I'm now reading about multipart/form-data enctype and will try to develop this feature for WebClient (if the customer don't cancel the project). Will send the news. Cheers.

Help with petitparser
by Adrien BARREAU June 2, 2010

June 2, 2010

Hello, I need some help with petitparser. I encountered 2 problems. Here they are: - I don't find to way in petitparser to: parse every string except a list of strings. For example, I want to parse all string except 'string' and 'STRING'. - I don't find a way to parse a string without taking care of its case. For example, I want to parse 'string', 'STRING', 'String', 'stRINg', etc ... I hope you'll can help me :) Adrien. _________________________________________________________________ La boÃ®te mail NOW GÃ©nÃ©ration vous permet de rÃ©unir toutes vos boÃ®tes mail dans Hotmail ! http://www.windowslive.fr/hotmail/nowgeneration/
