seL4 – Open source formally verified bug free microkernel OS released

General Dynamics C4 Systems and NICTA are pleased to announce the open sourcing of seL4, the world’s first operating-system kernel with an end-to-end proof of implementation correctness and security enforcement. It is still the world’s most highly-assured OS.

What’s being released?

It includes all of the kernel’s source code, all the proofs, plus other code and proofs useful for building highly trustworthy systems. All is under standard open-source licensing terms — either GPL version 2, or the 2-clause BSD licence.

Unique about seL4 is its unprecedented degree of assurance, achieved through formal verification. Specifically, the ARM version of seL4 is the first (and still only) general-purpose OS kernel with a full code-level functional correctness proof, meaning a mathematical proof that the implementation (written in C) adheres to its specification. In short, the implementation is proved to be bug-free (see below). This also implies a number of other properties, such as freedom from buffer overflows, null pointer exceptions, use-after-free, etc

UNetbootin – create a USB bootable linux drive

UNetbootin allows you to create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions without burning a CD. It runs on Windows, Linux, and Mac OS X. You can either let UNetbootin download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you’ve already downloaded one or your preferred distribution isn’t on the list.

Data visualisation packages

To bring your data to life, there are plenty of options around.

D3 is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation.

As you can see, there are loads of different graphs, graphics, plots, etc you can generate to display your data differently.

Bokeh is a Python interactive visualization library for large datasets that natively uses the latest web technologies. Its goal is to provide elegant, concise construction of novel graphics in the style of Protovis/D3, while delivering high-performance interactivity over large data to thin clients

The advantage these packages have over, say, IBM ManyEyes is that they are locally installed and you don’t give your data away.
