Whonix is an anonymous general purpose operating system based on Virtual Box, Ubuntu GNU/Linux and Tor. By Whonix design, IP and DNS leaks are impossible. Not even malware with root rights can find out the user's real IP/location.

Whonix consists of two machines, which are connected through an isolated network. One machine acts as the client or Whonix-Workstation, the other as a proxy or Whonix-Gateway, which will route all of the Whonix-Workstation's traffic through Tor. This setup can be implemented either through virtualization and/or Physical Isolation.

It's great to see Africa starting to explore the benefits of open source not only as a way of rolling out software more cheaply than would be the case for proprietary programs, whose Western pricing makes them particularly costly for emerging nations, but also as an effective means of building up a vibrant indigenous software industry that is not based simply on shovelling lots of money to the US.

However, it's sad to see that Microsoft seems to have learned nothing from its earlier, unsuccessful attempts to spread FUD about open source, and seems intent on recapitulating that shabby and rather pathetic history in Africa too.

w3af is a Web Application Attack and Audit Framework. The project's goal is to create a framework to find and exploit web application vulnerabilities that is easy to use and extend..

In this webinar you will learn the key differences between Zimbra Collaboration Server and Microsoft Exchange. Discover how next-generation products like Zimbra are dramatically lowering TCO and improving user productivity.

Ansible is a radically simple model-driven configuration management, deployment, and command execution framework. Other tools in this space have been too complicated for too long, require too much bootstrapping, and have too much learning curve. Ansible is dead simple and painless to extend. For comparison, Puppet and Chef have about 60k lines of code. Ansible’s core is a little over 1000 lines.

...

Where Ansible excels though, is expressing complex multi-node deployment processes, executing ordered sequences on different sets of nodes through Playbooks. Playbooks contain one or more plays, each executed against a different batch of nodes. Think about webservers, database servers, and backend servers in a multi-node web environment. A play can address each set of machines in a cycle, ensuring the configurations of the machines were correct and also updating them to the specified version of software if required.

At the end of the 1990s, Korea developed its own encryption technology, SEED, with the aim of securing e-commerce. Users must supply a digital certificate, protected by a personal password, for any online transaction in order to prove their identity. For Web sites to be able to verify the certificates, the technology requires users to install a Microsoft ActiveX plug-in.

...

It forced consumers to use Internet Explorer because it was the only browser ActiveX plug-ins were compatible with. By default, Web developers optimized not only banking and shopping Web sites for Internet Explorer, but all Web sites.

Unsurprisingly, this later caused all sorts of problems. And this, kids, is why "standardizing" on a vendor-specific solution, as opposed to an actual open standard, is an idiotic idea.

Linux system administrators often receive complaints about the performance of their systems.

It can be rather difficult to track down these problems and to find why, when, and how often they happen. Being able to zoom in on the processes that are responsible, and to see what has happened in the past, is very valuable.

The atop utility was written with just these things in mind.

Sikuli is a visual technology to automate and test graphical user interfaces (GUI) using images (screenshots). Sikuli includes Sikuli Script, a visual scripting API for Jython, and Sikuli IDE, an integrated development environment for writing visual scripts with screenshots easily. Sikuli Script automates anything you see on the screen without internal API's support. You can programmatically control a web page, a Windows/Linux/Mac OS X desktop application, or even an iphone or android application running in a simulator or via VNC.

calibre is free and open source e-book computer software that organizes, saves and manages e-books, supporting a variety of formats. It also supports e-book syncing with a variety of popular e-book readers and will, within DRM restrictions, convert e-books between differing formats.

That blurb is from Wikipedia. The site itself has a demo video. The app looks really nifty.

The purpose of beets is to get your music collection right once and for all. It catalogs your collection, automatically improving its metadata as it goes using the MusicBrainz database. (It also downloads cover art for albums it imports.) Then it provides a bouquet of tools for manipulating and accessing your music.
