GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content (text, graphics, mathematics, interactive content, etc.). The rendering engine uses high-quality typesetting algorithms so as to produce professionally looking documents, which can either be printed out or presented from a laptop.

An Inkscape plugin that allows to organize a set of slides on top of Inkscape layers.
The plugin allows to export the slides as a pdf file composed by several pages, each one corresponding to one slide.

Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.

zbackup is a globally-deduplicating backup tool, based on the ideas found in rsync. Feed a large .tar into it, and it will store duplicate regions of it only once, then compress and optionally encrypt the result. Feed another .tar file, and it will also re-use any data found in any previous backups. This way only new changes are stored, and as long as the files are not very different, the amount of storage required is very low. Any of the backup files stored previously can be read back in full at any time. The program is format-agnostic, so you can feed virtually any files to it.

This is achieved by sliding a window with a rolling hash over the input at a byte granularity and checking whether the block in focus was ever met already. If a rolling hash matches, an additional full cryptographic hash is calculated to ensure the block is indeed the same. The deduplication happens then.

Mathomatic™ is a portable, command-line, educational CAS and calculator software, written entirely in the C programming language. It is Free and Open Source Software (FOSS), published under the GNU Lesser General Public License (LGPL version 2.1), and has been under continual development since 1986. The software can symbolically solve, simplify, combine, and compare algebraic equations, simultaneously performing generalized standard, complex number, modular, and polynomial arithmetic, as needed. It does some calculus and is very easy to compile/install, learn, and use.

A long list of top python projects in 2014.

Pybtex reads citation information from a file and produces a formatted bibliography. BibTeX style files are supported. Alternatively it is possible to write styles in Python.

Pybtex currently understands the following bibliography formats:

• BibTeX
• BibTeXML
• YAML-based format

The resulting bibliography may be output in one of the following formats (not supported by legacy BibTeX styles):

• LaTeX
• HTML
• markdown
• plain text

HandBrake is a tool for converting video from nearly any format to a selection of modern, widely supported codecs. Converts video from nearly any format. With an easy-to-use GUI.

Photoshop is one of the most used image editing applications around. But how easy is it for a user to switch from Photoshop to the GIMP when they move from a Mac to Linux? A redditor is doing just that and wanted some feedback from his fellow Linux users.

This guide shows how you can install and use incron on a Debian 8 (Jessie) system. Incron is similar to cron, but instead of running commands based on time, it can trigger commands when file or directory events occur (e.g. a file modification, changes of permissions, etc.).

Syntastic is a syntax checking plugin for Vim that runs files through external syntax checkers and displays any resulting errors to the user. This can be done on demand, or automatically as files are saved. If syntax errors are detected, the user is notified and is happy because they didn't have to compile their code or execute their script to find them.
