So you’re up for some fast, old skool, 2D, platform, shoot ‘m up action! Well you came to the right place. Smash Battle, a game based on the famous Mario battle from Super Mario Bros 3 on the good old NES. The game is simple yet very addictive. Fight your way through several missions to unlock secret characters. Battle with one, two or even three friends in the multiplayer mode to show of your old and dusty game skillz.

It's not qmail. It's also not netqmail.

notqmail is a community-driven fork of qmail. notqmail begins where netqmail left off: providing stable, compatible, small releases to which existing qmail users can safely update. notqmail also aims higher: developing an extensible, easily packaged, and increasingly useful modern mail server.

The web platform is the delivery mechanism of choice for a ton of software these days, either through the web browser itself or through Electron, but that doesn’t mean there isn’t a place for a good old fashioned straight-up desktop application in the picture.

Fortunately, it’s easier than ever to write a usable, pretty, and performant desktop app, using my language of choice (Rust) and the wildly successful cross-platform GUI framework GTK.

GUI prototyped using Glade.

Snap! is a broadly inviting programming language for kids and adults that’s also a platform for serious study of computer science.

Snap! is now a community website where you can share and publish projects so others can find and remix them, and where you can ask questions and discuss the beauty and joy of computing. We invite you to check out the new site. Did you know that you can embed Snap! projects in other web pages?

We've also enhanced the programming language, making it easier to discover and to use powerful blocks for analyzing data and transforming media.

Vorta is a backup client for macOS and Linux desktops. It integrates the mighty BorgBackup with your desktop environment to protect your data from disk failure, ransomware and theft.

Abricotine is an open source, cross-platform Markdown editor built for the desktop with inline preview functionality.

Drill is a new file search utility that uses "clever crawling" instead of indexing, for Linux, Windows and macOS.

Why another editor?
With so many great markdown editors out there, the question remains why another one is necessary. I am a political theorist and therefore need to read a huge amount of texts as well as keep notes for each and every one. This makes it necessary that I keep all of my files as open as possible and also searchable.

Additionally, I tend to write my papers using as little markup and styles as possible. Word processors as Microsoft Word or LibreOffice are simply not made for easy and focused writing. That's why there is Markdown. It keeps apart your content and your final styling of a text. This way you are not distracted by all the neat formatting options word processors offer you and focus only on your content. Styling is applied in a second step.

Zettlr solves all of these problems in one single app. With Zettlr I can write in one file, simultaneously copy text from other files and finally export my papers using the powerful open source platforms pandoc and LaTeX. Simply put: Zettlr is the get-together of the best features of existing solutions and a supercharged approach to your own workflow!

I recently built a small agent-based model using Python and wanted to visualize the model in action. But as much as Python is an ideal tool for scientific computation (numpy, scipy, matplotlib), it's not as good for dynamic visualization (pygame?).

You know what's a very mature and flexible tool for drawing graphics? The DOM! For simple graphics you can use HTML and CSS; for more complicated stuff you can use Canvas, SVG, or WebGL

Flameshot is an easy to use, open source, Qt-based screenshot utility which is adept at capturing custom areas of a desktop.

FSearch is a fast file search utility for GNU/Linux operating systems, inspired by Everything Search Engine. It’s written in C and based on GTK+3.

Features

• Instant (as you type) results
• RegEx support
• Wildcard support
• Filter support (only search for files, folders or everything)
• Fast sort by filename, path, size or modification time
• Include and exclude specific folders to be indexed
• Ability to exclude certain files/folders from index using wildcard expressions
• Customizable interface

TimeShift for Linux is an application that provides functionality similar to the System Restore feature in Windows and the Time Machine tool in Mac OS. TimeShift protects your system by taking incremental snapshots of the file system at regular intervals. These snapshots can be restored at a later date to undo all changes to the system.

Snapshots are taken using rsync and hard-links. Common files are shared between snapshots which saves disk space. Each snapshot is a full system backup that can be browsed with a file manager.

TimeShift is similar to applications like rsnapshot, BackInTime and TimeVault but with different goals. It is designed to protect only system files and settings. User files such as documents, pictures and music are excluded. This ensures that your files remains unchanged when you restore your system to an earlier date. If you need a tool to backup your documents and files please take a look at the excellent BackInTime application which is more configurable and provides options for saving user files.

TimeShift is a system restore tool for Linux. It provides functionality that is quite similar to the System Restore feature in Windows or the Time Machine tool in MacOS. TimeShift protects your system by making incremental snapshots of the file system manually or at regular automated intervals.

Tilix is an advanced GTK3 tiling terminal emulator that follows the Gnome Human Interface Guidelines.

Snap! (formerly BYOB) is a visual, drag-and-drop programming language. It is an extended reimplementation of Scratch (a project of the Lifelong Kindergarten Group at the MIT Media Lab) that allows you to Build Your Own Blocks.

It also features first class lists, first class procedures, and continuations. These added capabilities make it suitable for a serious introduction to computer science for high school or college students.
