Klavaro is a very flexible touch typing tutor, supporting customizable keyboard layouts. You can edit and save new or unknown keyboard layouts, as the basic course was designed to not depend on specific ones. Also, there are some charts about the learning process, and for advanced users an online ranking scheme, comparing your typing proficiency with others.Its interface is very simple, without artifacts to distract the user, and some may find this boring, but we think keyboard memorization requires a high level of concentration, and must be done by touch, not visually.

Scrivano is a note-taking application aimed at those who prefer handwriting over typing. It offers a simple and easy to use interface to write down your thoughts and ideas. The app gives you an infinite vertical canvas (but limited horizontal space) without sacrificing the ability to easily export your notes in traditional printing formats (e.g. A2, A3, A4, etc...).Here is a summary of the most important features:4 different paper backgrounds to choose from: Plain, Lined, Grid or Dotted with customisable spacing and backgrounds.Grid Snapping: in Scrivano you can toggle the grid snapping feature so that your drawings will automatically snap to grid lines in the background. This is very useful to easily draw tables, diagrams and lines.Automatic filling of strokes: toggle the paint bucket in the toolbar to fill your drawing shapes and strokes.Stickers: save your frequently used symbols and diagrams, so you can easily drag and drop whenever you need them.Insert images: paste or drag and drop any image on the canvas to unleash your creativity!Offline saving: save your notes anywhere on your main drive, so you can manage them however you please.Laser: Scrivano offers a special laser tool to quickly draw over your notes. Incredibly useful when sharing your screen or presenting something!Annotate PDF files: You can import your PDF books, lecture slides, articles and documents to annotate them using Scrivano's built-in inking tools.NOTE: The flatpak version of the app runs in a sandbox environment and it can only read/write files from these folders: xdg-desktop, xdg-documents, xdg-download and xdg-pictures. If you want to circumvent this for more freedom, you can use Flatseal to override these restrictions.

Genius is a general purpose calculator program similar in some aspects to BC, Matlab, Maple or Mathematica. It is useful both as a simple calculator and as a research or educational tool. The syntax is very intuitive and is designed to mimic how mathematics is usually written. GEL is the name of its extension language, it stands for Genius Extension Language, clever isn't it? In fact, many of the standard genius functions are written in GEL itself.What can it do?Arbitrary precision integers, multiple precision floats.Complex numbers, stored in Cartesian coordinates as usual.Math-like-looking expressions, tries to be as much a what-you-mean-is-what-Genius-understands, up to a limit of course.Matrix calculations / Linear Algebra, with many related functions.Number theory.Calculus, numerical and even very limited symbolic calculations.Statistics, all the basic statistical functions.Numerical equation solving, polynomial roots, etc...Combinatorics.Most common elementary / trigonometric functions.Modular arithmetic, including inversions and modular arithmetic on matrices.A complete programming language, with automatic typing. In fact large part of Genius standard library is written in GEL.2D Function line plots, standard 2D graphs of up to 10 functions at once, with possibility to export to EPS or PNG.Parametric plots, with possibility to export to EPS or PNG.3D Function surface plots, with possibility to export to EPS or PNGSlopefield/Vectorfield plotting.GUI IDE where you can edit and run/test your programs.Can output matrices in LaTeX, Troff (eqn) or MathML, this is I think a very cool feature that allows you to copy stuff directly from Genius to a document in LaTeX, troff or MathML.

SciDAVis is a free interactive application aimed at data analysis and publication-quality plotting. It combines a shallow learning curve and an intuitive, easy-to-use graphical user interface with powerful features such as scriptability and extensibility. SciDAVis runs on GNU/Linux, Windows and MacOS X; possibly also on other platforms like *BSD, although this is untested.SciDAVis is similar in its field of application to proprietary Windows applications like Origin and SigmaPlot as well as free applications like QtiPlot, Labplot and Gnuplot.What sets SciDAVis apart from the above is its emphasis on providing a friendly and open environment (in the software as well as the project) for new and experienced users alike. Particularly, this means that we will try to provide good documentation on all levels, ranging from user’s manual over tutorials down to and including documentation of the internal APIs We encourage users to share their experiences on our forums and on our mailing lists.More information, including screenshots, reviews, current contributors can be found on the SourceForge project webpage.
