rubric in glamour
by Tudor Girba 04 Jun '13

04 Jun '13

Hi, I started to integrate Rubric in Glamour. At the moment, only the basic text widget is integrated, and it is integrated with a different factory method (rubricText instead of text). The longer term idea is to replace the rendering of the existing TextPresentation. Once TxText will be adopted we will move again. Furthermore, the interface is basic, but given that Rubric offers a couple of nice features (such as decorations and wrapping), we should adopt that as well in the interface. An example: wrapper := GLMCompositePresentation new. wrapper with: [ :w | w show: [ :a | a rubricText ] ]. wrapper openOn: 'text' Cheers, Doru -- www.tudorgirba.com "Things happen when they happen, not when you talk about them happening."

Hmm, What combination of configurations, images , vm, plugins is supposed to work? cairo install through port is broken on 10.6.8 with xcode 4.0.2, glib2 won't compile. I'm not very happy with package management on mac, btw. Brew interferes with port... Stephan

Hi, Andrei joined Camillo and extended a bit the ZeroConf infrastructure to make it easy for other projects to generate install scripts. As a consequence, we now have: http://get.moosetechnology.org The Moose-specific customization code can be found in the Moose-Development-Tools package from: http://www.smalltalkhub.com/mc/Moose/Moose/main The scripts are generated via the Pharo command line like: Pharo/pharo-ui moose-latest-dev-4.8.image moosezeroconf Cheers, Doru -- www.tudorgirba.com "No matter how many recipes we know, we still value a chef."

I do not get it. There is no magic in scaling (of course you have the algorithms) but after I remember the discussion with igor about matrixes. So if we do not use what athens provides then roassal will get slower. >

We incrementally incorporate Mathieu's work in the mainstream of Roassal. are you working on using athens transformation into roassal? Because this will provide speed up. >> - do you see athens as just another canvas (in addition to morphic) where things are drawn?

Athens does not handle event as far as I know. For now Athens is a rendering canvas. It is lowest part. Event are Morphic stuff. > If an animation support is offered for Athens, we will then try to use it (if it is faster than the one we have currently in Roassal). Athens will not support animation. Another framework will use athens to render animation. Igor showed me some sketches and this is promising. > >> - what are the potential speed up points that you see where Roassal can be improved apart from using Athens? > > No idea. So far, I haven't seen any speedup, but rendering in Athens is much nicer. But are you using athens transformation? Because this is what we should do. >> - A more general question. We can render 5K or 10K nodes with Roassal today but the problem is that its so slow that we cannot use it. How do you measure the increase in performance apart from merely a time factor because 10secs might just be as acceptable as 1sec if the user is informed. So, we can have two parts: first the display creation part, that's normal that some computations take time and then the interaction part, which should be optimized. > > Well... we microbench Roassal for the rendering and interaction. > >> - Do you want to revisit the announcements part in Roassal because we saw sometimes ago that some announcements in Roassal were not garbage-collected and stayed in the memory? > > Recently we have built a memory profiler and we spotted many places in Roassal that produces unnecessary instances.

ESA Summer of Code - BRL-CAD Refactoring
by Ben Coman 03 Jun '13

03 Jun '13

Inspired by GSoC is the European Space Agency Summer Of Code. One of the project ideas [1] is refactoring BRL-CAD. Perhaps someone knows of a student that might like to apply Moose to the problem. Stipend of 4000 Euros [2], and possibly an opportunity to use it as a case study for Moose, and publicize Moose/Pharo to the "defense" community, who have plenty of funds and long lived projects that might benefit from software analysis tools. About BRL-CAD [3]: "For more than 20 years, BRL-CAD has been the primary tri-service solid modeling CAD system used by the U.S. military to model weapons systems for vulnerability and lethality analyses. The solid modeling system is frequently used in a wide range of military, academic, and industrial applications including in the design and analysis of vehicles, mechanical parts, and architecture. The package has also been used in radiation dose planning, medical visualization, computer graphics education, CSG concepts and modeling education, and system performance benchmark testing among other purposes. BRL-CAD is a collection of more than 400 tools, utilities, and applications comprising more than a million lines of open-source code."
