Thanks a lot. Esteban is travelling/on holiday so he will check that soon I imagine.

Re: [Pharo-dev] Initial versions for OSWindow and Woden

by stepharo

Hi ronie I should sync with igor to understand what is the path to integrate what you did with him. Because I want new events and what you and igor did (or at least I do not want to lose all the event cleaning I did long time ago). I wish a lot of success to Woden :) Stef On 31/5/14 11:54, Ronie Salgado wrote: > Hello There, > > I have been working in OSWindow, which is a cross platform API for > dealing with native operating system windows.

Re: [Pharo-dev] GPU accelerated GUI

by stepharo

It depends what you measure. If you measure classBrowser opening then nautilus is slower because it is doing more stuff. Now we invested a lot in - cleaning morphic and we will continue. We fixed broken rectangles (around 150 creation), added Margin to avoid ifTrue: removed many of the totally useless extensions. Now we do it step by step because it takes time and we try to understand what we remove!!! - in Spec, spec is a MVP like system. Now building one takes time and ben did a great job. Now we should check if he will continue or not (it depends on him and his job). We should probably do a pass on Spec. Alain Plantec is rewriting core morphic from scratch and it is quite fast. He just shows me this after how he can package halos as a separate package. Now the risk is high because Alain does not have the amount of time he would like to work on that. So if you really want to help make a benchmark showing the difference between 1.4 and 3.0 on a **concrete** case. Without that we cannot make progress.

I tried comparing my slaves with the ones used in Pharo and I didn't take it much further. Additionally, if I connect to the slave through remote desktop (:puke:), and try to execute the zero conf script with the same user, on the same folder from a msys console, I have no errors. > > Maybe someone has an idea? :) Indeed. Very strange. You can find all environment variables available to your jenkins job for this slave here: https://ci.inria.fr/dbxtalk/computer/dbxtalk-windows-32bit/systemInfo There are some other variable added on the fly, depending on your job config (values of axis in matrix jobs for example). I defined a test job to debug that: https://ci.inria.fr/dbxtalk/job/test-zeroconf/8/console The error comes from the http://get.pharo.org/vm. It looks like a permission problem to write in the workspace of your slave. Hope this helps, Christophe.

Fwd: [Pharo-users] [SummerTalk] Refactoring in Pharo

by Damien Cassou

---------- Forwarded message ---------- From: Mark Rizun <mrizun(a)gmail.com> Date: Mon, Jun 2, 2014 at 4:19 PM Subject: [Pharo-users] [SummerTalk] Refactoring in Pharo To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> Hi guys! I'm happy to announce you, that I will be working on SummerTalk project entitled "Refactoring in Pharo" with RMoD. Obviously, it's about refactoring system in Pharo. The goal of this project is to improve existing refactrings in Pharo and add some new ones. If you are interested in this topic please visit my blog for more details: http://myfuncoding.blogspot.com/ After some work is done, I'll publish info here and on my blog. Also, source code will be available on my smalltalkhub, and it's going to be soon ;) Thoughts and feedback are welcome.

Re: [Pharo-dev] String deduplication

by Chris Muller

This is a normal pattern in application-development. For example, Todd Blanchard's HTML validating parser grabs a huge chunk of HTML, and all the parts are simply referenced by position within that big String.

That's true, the most important ideas are already protected. I hope to have a working version before the end of this year. There will be some performance impact, mostly due to the use of Float geometry instead of SmallInteger. Hopefully Eliot's Spur with immediate Floats will compensate for that. But I have done some benchmarks, and the Morphic 3 graphics engine is twice as fast as Cairo, and almost as fast as AGG (Anti-Grain Geometry). Cheers, Juan Vuletich
