Re: [Pharo-project] Differential and Integral calculus in Pharo?

by Nicolas Cellier

There is also StMath in Visualworks Or maybe you could try to exhumate MathMorphs? Differentiation is easy, and you can have fun implementing your own... Integral calculus though is a tougher subject. Nicolas 2012/8/2 Clara Allende <clari.allende(a)gmail.com>: > Thanks for all your answers guys!

Thanks for all your answers guys! This is very interesting :) @Guille yes, I know and I already told you yesterday that I will study for tomorrow's exam and then play with crazy math stuff in Pharo :P @Serge I took a look at your work (and Daniel's), it is awesome!

It's not hit the top of my todo list, but it is ON the list.

[Pharo-project] RPackageOrganizer does not unregister when we unload MC ?

by Mariano Martinez Peck

RPackageOrganizer default packages select: [:each | each name = 'HistoryCollection'] -> an Array(a RPackage(HistoryCollection)) (MCPackage named: 'HistoryCollection') workingCopy unload. RPackageOrganizer default packages select: [:each | each name = 'HistoryCollection'] -> an Array(a RPackage(HistoryCollection)) I would expect the last line to answer empty... is this a bug? -- Mariano http://marianopeck.wordpress.com

[Pharo-project] R.I.P. FileDirectory

by Esteban Lorenzano

Hi, In update 20240 we finally completed the unload of FileDirectory. From now, just FileSystem is available to manipulate files... AFAIK, this is the biggest (and almost the only) "incompatible" change from 1.4 to 2.0, so I recommend framework developers to start your migration right now, so they are usable by 2.0. Don't wait until it is to late! :) (Also, that can be useful to detect FileSystem bugs now, and not next year) Cheers, Esteban
