[Pharo-project] [CogVM] glitch: OS X fullscreen with borders

by Max Leske

I discovered a small glitch in the fullscreen support on OS X: if you set the OS X dock to always show and then go into fullscreen mode, the window will have a top and bottom border of about the height of the dock (see screenshot). Cheers, Max

Hi, Doing nice formulas in Pharo would be of interest to me. And manipulating them even more (I am busy with that now). As for Geogebra as competition, these guys are now doing a ton of 3D (we use GG here with my wife, a maths teacher) and their DSL is pretty useful once mastered. I find myself constructing a lot of things from the little "command prompt" of theirs. That would be an interesting addition to DrGeo (and why not being GG-compatible on the commands). I know I can get a browser and all, but that's not cutting it the same way. DrGeo is Java-free, so where can we use it where Java is not fine? I'll look at what I can propose for engineers to work on. I'd add that a solver for constraints would be nice to have (like Simplex). Also, a good thing to add to DrGeo is a window with a list of entities with their name and possibility to rename/change attributes from there.

[Pharo-project] Questions on Traits

by Noury Bouraqadi

Hi, -Why new methods are compiled from the ones of traits? I remember that in the first implementation, when a trait was used by a class, new entries were introduced to the methodDict where the values are the compiled methods from the trait. Currently, a new compiled method is introduced with the exact code of the on from the trait. Why? -It is possible to compile a method that includes a super send in traits. Does it make sense?
