<h2><a href="http://harvey-os.org/">Harvey OS</a></h2>

<p>Harvey is a new operating system. It’s most directly descended from Plan 9, the research operating system developed at Bell Labs as a successor to Unix. This influence spans from its distributed application architecture all the way down to much of its code. However, Harvey aims to be a more practical, general-purpose operating system, so it also uses ideas and code from other systems.</p>

<p>Harvey strives to provide an accessible development environment. The kernel is compact—less than 100,000 lines of code. You can build it with either GCC or LLVM, and run it under QEMU or real hardware. This makes it especially suitable for education and experimentation. It is a work in progress and the development team welcomes new contributors and ideas.</p>

<h2><a href="http://brew.sh/">Homebrew</a></h2>

<h2><a href="https://inkscape.org/">Inkscape</a></h2>

<p>Inkscape is an Open Source vector graphics editor, with capabilities

similar to Illustrator, Freehand, CorelDraw, or Xara X using the

open-standard Scalable Vector Graphics (SVG) file format. Inkscape's

main goal is to create a powerful and convenient drawing tool fully

compliant with XML, SVG, and CSS standards.</p>

<p>In contrast to raster (bitmap) graphics editors such as Photoshop or

Gimp, Inkscape stores its graphics in a vector format. Vector graphics

is a resolution-independent description of the actual shapes and

objects that you see in the image. This description is then used to

determine how to plot each line and curve at any resolution or zoom

level.</p>
