news 28 Posted October 6, 2014 Genius is a general purpose calculator with many advanced capabilities. To find out more go to: http://www.jirka.org/genius.html Time to break traditions so a new genius release just a month (not a year) after the last one. The reason are a few cool features, like a preinstalled list of examples (or demos if you will), drawing curves in the surface plots, and most of all fixing a funky bug, string starting with 'E' from the compiled standard library were eaten by 1.0.18. Anyway, the list of examples should make for a more fun release, they are mostly taken from demos I did in class at various points. So the hope is that this way people will find out better what can be done with genius. In any case, Genius is one of the oldest GNOME projects going back to late 1997. It was the original GNOME calculator before I got wild ideas about it doing absolutely everything. It is programmable, has a powerful language and handles many fun features including support for matrices, rational numbers, and nice 2D and 3D plotting. The GUI version requires GNOME2 (at least glib2 if you don't want a GUI) a recent enough GMP library and the MPFR library. You can still use the command line version if you prefer non-gui interface. Here are the news in 1.0.19: * New menu: Examples. These are annotated programs that show some mathematical concept. Generally taken from the classes I have been teaching. They are installed under prefix/share/genius/examples/ and are mostly using graphics so only work in the graphical GNOME/GTK version * New plotting functions: SurfacePlotDrawLine, SurfacePlotDrawPoints, SurfacePlotClear, PlotWindowPresent * New rotation animation in the surface plot window * Fix string constants from compiled library starting with 'E' (funky bug) * A few fixes * Translation updates (Miguel RodrÃÂguez Núñez, Daniel Mustieles, Wolfgang Stöggl, Marek Černocký) * During making of these changes the author (Jiri) was partially supported by NSF grant DMS 1362337 and the Oklahoma State University http://download.gnome.org/sources/genius/1.0/ ftp://ftp.5z.com/pub/genius/ http://www.jirka.org/genius.html Genius is in Ubuntu, Debian, Fedora, GARNOME, OpenSUSE, and probably other distribution repositories, so check those. Usually you want to install two packages: genius and gnome-genius (perhaps also gnome-common on some distros). Of course, it will be a little bit before this version hits those servers ...
