[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

Re: [Pharo-project] Possible FFI issue

by Diego Lont

Hi all, Ok, an update. We tried a different access driver, and this also solves the problem. So for now, we are helped enough.

Re: [Pharo-project] [Preview] The Alternative Browser

Ok, I made a screencast. http://ubuntuone.com/70xFLiJjNRbCGdpVGVIE97 It shows mouse-based navigation, buggy drag and drop, as well as keyboard navigation in the entire system, and a few things that are interesting to see : an empty System-Text package, for example. It's done on the base one-click 2.0 image.

Maxima is pretty cool indeed. For inspiration, wxMaxima is a UI built on top. That's what we use over here for maths stuff with my wife. There is also Octave for numerical computing, Maxima being on the symbolic side. 2012/8/2 Lawson English <lenglish5(a)cox.net> > Recently, I ran into this: http://maxima.sourceforge.net/ > > an interface/binding lib might be easier than writing your own from > scratch. > > > L > > > On 8/1/12 3:03 PM, Clara Allende wrote: > >> Hi guys, after having exhausting four months of Physics lessons, I >> decided that would be fun to write a program to deal with Electricity >> problems :) (Yeah, I'm not a normal person :P) >> >> So, I need to make differential and integral calculus, are there any >> libraries to do so?
