TIC-80 is a free and open source fantasy computer for making, playing and sharing tiny games.With TIC-80 you get built-in tools for development: code, sprites, maps, sound editors and the command line, which is enough to create a mini retro game.Games are packaged into a cartridge file, which can be easily distributed. TIC-80 works on all popular platforms. This means your cartridge can be played in any device.To make a retro styled game, the whole process of creation and execution takes place under some technical limitations: 240x136 pixel display, 16 color palette, 256 8x8 color sprites, 4 channel sound, etc.Note: Access to all devices permission required (--device=all) so that gamepads can be used with this Flatpak.

The app exists in several packages: Flatpak, Snap, PyPI and can be installed on Linux, RaspberryPI, all ARM, Mac, Windows (Cygwin), Android (Termux).Works with Python and NcursesThe app is very low in memory and CPU usageCheck my website if you need more graphical interfaces. The app has two brothers :)Bibles included: King James Version, Segond, Ostervald, Diodati, Reina Valera, Almeida, SchlachterPlease share the info with your friends. Time is short. Tribulations are at the door. ** All The Glory To God.For the story: the app was created after Bible Multi The Light (Android) and before Bible Multi The Life (Android, iPhone, iPad, Big Sur, Mac, Linux). You can find them on their stores and F-Droid.If you have problem in your Terminal when quitting the application, type "reset" to restore the terminal or CTRL-DIf characters are missing, please install the utf8 characters with "sudo dpkg-reconfigure locales": select en_US, es_ES, fr_FR, it_IT, pt_PT (UTF8). But it also works with en_GB, fr_BE...

Artikulate is a pronunciation trainer that helps improving and perfecting a learner's pronunciation skills for a foreign language. It provides courses with native speaker recordings for several training languages. The learner downloads those courses, selects a category of phrases to train, then starts with recording her/his own voice when speaking the phrases and comparing the results to the native speaker's recordings by listening to both. By adjusting and repeating the own pronunciation, the learner can improve his/her skill.

Artikulate

The Engauge Digitizer tool assists in interactively extracting numbers from images of graphs. Conceptually, it is thus the opposite of a graphing tool that converts data points to graphs. It provides assistance in enhancing the image quality and matching the data points. Engauge Digitizer is used by individuals such as grad students and researchers as well as engineers and employees in large government and commercial organizations for processing single files but also managing databases of thousands of image files.Features of Engauge Digitizer include:Automatic grid line removalAutomatic point and axis matchingAutomatic curve tracingImage processing for separating important details from background informationA wizard providing an interactive tutorial to explain the basic stepsMultiple coordinate systems in the same image can be digitized in advanced modeCubic spline interpolation between points gives more accurate curves with fewer pointsHandling of cartesian, polar, linear and logarithmic graphsSupport for drag-and-drop and copy-and-pasteContext-sensitive help, user manual and tutorials explaining every featurePreview windows to give immediate feedback while modifying settingsAutomated line and point extraction to rapidly digitize data

JClic is formed by a set of multimedia applications that are used for carrying out different types of multimedia and interactive educational activities: puzzles, associations, text exercises, crosswords, etc.The activities are usually packed in projects. A project is formed by a set of activities and one or more sequences, which indicate the order in which they have to be shown.Since 1995 teachers from different countries have contributed to a big repository of educational activities which work on procedures of diverse curricular areas, from kindergarten up to secondary education and shared under Creative Commons licenses.The JClic suite is composed by this applications:JClic Player: allows students to play with the activities and, optionally, track reports of their work in a local or remote databaseJClic Author: a visual tool used by teachers and authors to create or modify activities and projects
