Open Source Software for Linux
TurboVNC
TurboVNC is a derivative of VNC (Virtual Network Computing) that is tuned to provide peak performance for 3D and video workloads. TurboVNC was originally a fork of TightVNC 1.3.x, and on the surface, the X server and Windows viewer still behave similarly to their parents. However, the current version of TurboVNC contains a much more modern X server code base (based on X.org 7.7) and a variety of other features and fixes not present in TightVNC, including a high-performance Java viewer. In addition, TurboVNC compresses 3D and video workloads significantly better than the “tightest” compression mode in TightVNC 1.3.x while using only typically 15-20% of the CPU time of the latter. Using non-default settings, TurboVNC can also match the best compression ratios produced by TightVNC 1.3.x for 2D workloads. Furthermore, TurboVNC contains some unique features that are designed specifically for visualization applications.
Zim
Zim is a graphical text editor used to maintain a collection of wiki pages. Each page can contain links to other pages, simple formatting and images. Pages are stored in a folder structure, like in an outliner, and can have attachments. Creating a new page is as easy as linking to a nonexistent page.
TigerVNC
TigerVNC is a high-performance, cross-platform implementation of VNC (Virtual Network Computing). The TigerVNC client/server application allows you to launch and interact with graphical applications on remote machines over the internet or a local network. TigerVNC provides the levels of performance necessary to run 3D and video applications, and it attempts to maintain a common look and feel and re-use components, where possible, across the various platforms that it supports. TigerVNC also provides extensions for advanced authentication methods and TLS encryption.
Notable
Notable simple yet powerful Markdown editor that features multi-cursors, a minimap and best-in-class syntax highlighting.
Avant Browser
Avant Browser is an ultra-fast web browser designed for the modern web. It provides a user-friendly interface that brings a new level of clarity and efficiency to your browsing experience, and frequent upgrades have steadily improved its reliability.
SQuirreL SQL
SQuirreL SQL is a free and open-source SQL client and database administration tool. SQuirreL SQL is written in Java and uses JDBC to allow users to explore and interact with databases via a JDBC driver. With SQuirreL SQL you can manage your database through a graphical user interface where you can create and drop tables, add columns and rows, create function and query your data. The software is openly developed and released under the GNU Lesser General Public License which makes it free to use.
Graphite
Graphite is a free and open-source, enterprise-ready software designed to monitors and graphs numeric time-series data. It can be used to monitor performance and data for software, web applications and computer systems. Companies like Etzy, GitHub, Lyft, Reddit and SalesForce trust and use Graphite to store and graph business critical metrics.
Apache Storm
Apache Storm makes it easy to reliably process unbounded streams of data for real-time processing. It is a distributed stream processing computation framework written predominantly in the programming language Clojure. The software is released free and open-source under the Apache License. In a nutshell, Apache Storm does to real-time processing, what Apache Hadoop did to bactch processing. Large corporations like Weather Channel, FullContact, Twitter, Yahoo, Spotify, and Alibaba use and trust Apache Storm for big data analytics with fault-tolerance and fast data processing.
Openswan
Openswan has been a popular VPN alternative for Linux users since2005. It is an IPsec implementation with support for most of its extensions (RFC and IETF drafts), even IKEv2, NAT Traversal, X.509 Digital Certificates and more. Openswan comes packages with various Linux distributions, including Gentoo, Fedora, Ubuntu, Red Hat and others.
