FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. It is designed to fit a wide range of uses including product design, mechanical engineering, architecture and 3D printing.FreeCAD allows you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production-ready drawings. it is a multiplatfom (Windows, Mac and Linux), highly customizable using the Python language. It reads and writes to many open file formats such as STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE and many others, making it possible to seamlessly integrate it into your workflow.FreeCAD includes a modern Finite Element Analysis (FEA) tools, experimental CFD, BIM, Geodata workbenches, a Path (CNC) workbench, a robot simulation module that allows you to study robot movements and many more, and a rich collection of plugins and macros installable directly from within the application.

Anki is a program which makes remembering things easy. Because it's a lot more efficient than traditional study methods, you can either greatly decrease your time spent studying, or greatly increase the amount you learn.Anyone who needs to remember things in their daily life can benefit from Anki. Since it is content-agnostic and supports images, audio, videos and scientific markup (via LaTeX), the possibilities are endless.Optional LaTeX support is provided by the TeX Live Flatpak extension org.freedesktop.Sdk.Extension.texlive//21.08.

GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable.Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. It is easily extensible and customizable via user-defined functions written in Octave's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.

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.

Tux Paint is a free, award-winning drawing program for children ages 3 to 12. Tux Paint is used in schools around the world as a computer literacy drawing activity. It combines an easy-to-use interface, fun sound effects, and an encouraging cartoon mascot who guides children as they use the program.Kids are presented with a blank canvas and a variety of drawing tools to help them be creative.

Tux Paint

Tux Paint's Color palette includes a new Color Mixer option, which allows users to combine different proportions of primary colors (red, yellow, and blue) and shades (white, grey, and black) to create new colors, similar to mixing paints.The Color Picker option, which previously offered a static palette of around sixty-five thousand color choices, now supports separate hue, saturation, and value settings, allowing users to choose from over sixteen million colors.Also, a keyboard shortcut is now available for quick access to the Color Selector — the "pipette" tool used for picking colors from the current drawing.The Paint and Lines tools now provide a way to adjust the spacing of brushes, allowing dotted lines or smearing effects to be made. Many brushes have been given better default spacing values, as well.Two new variations of the Zoom Magic Tool, Tile Zoom and Rush, have been added. When shrinking a drawing with Tile Zoom, it replicates the drawing across the canvas in tiles, rather than filling the canvas with a solid background color. The Rush tool blurs the results.Tux Paint's Shapes tool now offers hexagon (6-sided) and heptagon (7-sided) polygons. For shapes which can be stretched (rectangle, oval, etc.), the aspect ratio of the shape is displayed at the bottom while you make your adjustments. Instructional information shown while using some other tools has also been expanded.Keyboard shortcuts, such as [Control]+[S] to save a drawing, are now accessed with the more traditional [⌘ Command] key when using Tux Paint on macOS. Sizing of Tux Paint's built-in on-screen keyboard has been improved. The look and feel of the user documentation has been improved.

Tux Paint's Paint and Line tools now support brushes that rotate based on the angle of the stroke. This new rotation feature, as well as the older directional and animated brush features, are now visually indicated by the brush shape selector. Additionally, the Fill tool now offers a freehand painting mode for interactively coloring within a confined area.Six new Magic tools have been added to Tux Paint. Panels shrinks and duplicates the drawing into a 2-by-2 grid, which is useful for making four-panel comics. Opposite produces complementary colors. Lightning interactively draws a lightning bolt. Reflection creates a lake-like reflection on the drawing. Stretch stretches and squashes the picture like a fun-house mirror. Lastly, Smooth Rainbow provides a more gradual variation of Tux Paint's classic Rainbow tool.A number of existing Magic tools have been updated, as well. Improvements were made to Halftone, which simulates photographs on newsprint; Cartoon, which makes an image look like a cartoon drawing; and TV, which simulates a television screen. Additionally, Cartoon and Halftone, along with Blocks, Chalk, and Emboss, now offer the ability to alter the entire image at once!Finally, Magic tools are now grouped into collections of similar effects — painting, distorts, color filters, picture warps, pattern painting, artistic, and picture decorations — making it easier to find the tool you need.

Tux Paint's Fill tool now offers options to fill an area with color gradients. The "Radial" fill creates a circular gradient centered around the mouse click, while the "Linear" fill allows the interactive creation of gradients at different angles and sizes.New Magic tools have been added to Tux Paint: "Pixels" makes it easier to create retro-gaming style pixel art, "Checkerboard" fills the entire canvas with a check pattern, and "Clone" allows duplicating parts of the picture via brush strokes.Tux Paint's user documentation has been overhauled, making localization easier. Parties interested in helping with localization are encouraged to contact the Tux Paint team.Finally, a new pair of accessibility options have been added. The entire user interface can now be enlarged benefiting users with impaired vision, and making the program more suitable to very high density displays. This feature, along with a new option to re-organize the color palette, can also be helpful to users of coarse input devices, such as eye-gaze tracking systems.

A major improvement has been made to the Shapes tool, which now provides options to choose whether shapes are drawn from the center or a corner, making it easier to use in any situation.The on-screen keyboard, an accessibility feature optionally available when using the Text and Label tools, now appears larger on bigger displays; helpful for users of coarser input devices, such as eye-tracking systems.The Eraser tool adds new, smaller eraser sizes, and applies smoother, contiguous strokes when the pointer is moved quickly.Finally, this newest version adds options to export individual drawings and GIF animations, making it easy to share pictures, cartoons, and slideshows with others.

The latest version has promoted the "Fill" tool, previously found under the "Magic" section of Tux Paint, to the main toolbar, where it's easier to find. It also includes some performance improvements during start-up and when bringing up the "New" drawing dialog. The solid background colors can also be placed at the end of that dialog, allowing emphasis of template images.Tux Paint also now makes it possible to disable stereo sound, which can benefit users with a hearing impairment, or in situations where only one speaker is available.

New in this version are a "color picker", which allows any color within a drawing to be chosen using the pointer, and a set of three-, four-, and five-pointed star shapes.The latest version also incorporates a number of new translations, bringing the number of supported languages up to nearly 130: Bengali, Bodo, Dogri, Kabyle, Urdu, and Devanagari and Perso-Arabic variations of Kashmiri and Sindhi. Thirty other translations have been updated, as well.

We heard you! Following up on feedback we received in several channels, we removed the concept of a Hack mode from our first class learning environment. In Hack mode, the user had the hacking affordances available, namely the Flip to Hack functionality to look behind an application, see what is happening behind the scenes, modify the application and run it in a sandbox environment.To provide the user with a sense when those affordances were available, the desktop background wallpaper changed and the cursor switched to the Hack cursor. Those changes have been perceived as intrusive (“it spoils the system and it changes your cursor style”). We decided to reduce that barrier of adoption and removed changing the cursor and wallpaper. The hacking affordances are available by default and not tied to a specific mode, so you can still enjoy the Sidetrack quests and use the Hacking Toolbox on the flip side of the app to solve the riddles.We are very happy to announce that Hack is now fully open source. All of the components have been released under an open source license.Hack and it's components is now available outside of Endless OS. It will run on any GNOME based Linux system with (GNOME Shell: &gt;=3.36, Flatpak: &gt;1.8.2).Hack relies on a GNOME Shell extension to enable features like Flip to Hack. If the extension is not installed the user can instal it from within the Clubhouse UI.The dependency of the Maker and some Art quests on the Project Library app has been removed. The content is now shipped with the Clubhouse itself.The installation flow of apps needed by quests has been improved. The quest will open GNOME Software automatically with the required application detail page to guide the user through the installation process.The Clubhouse detects the network status. Feedback is shown if quests have network dependencies and can not run without a connection.
