So you want to do some sphere packing to make your inflatable space habitats for deployment on the Moon and Mars snug and cozy. Perfectly straightforward you think to yourself; since one can start with a triplet of spheres tangent pairwise by placing one at some origin on a 2D plane, extending the second out in the \(x\) direction and completing the triangle by identifying the third sphere's position based on the radii of all three.
One side project that has been sitting by the wayside since completing my PhD has been to polish up and publish Wafer: my fancy 3D wavefunction solver. For reasons, one of which is mostly structured procratstination, this polishing ended up being a port/re-write in Rust. Delving into the Rust ecosystem has been fun and if you check Wafer's commit history you'll notice large rewrites again and again as I basically play around with things; having no real development schedule or design restrictions.
It may seem a little counter intuitive then, that I'm also trying at the same time to learn all the rigid structures of software development. Proper documentation, testing, error handling, data structures etc.
Due to my erroneous assumption that an OVZ container is indistinguishable from a full OS on the inside, my VPS upgrade from Debian Wheezy to Jessie didn't go exactly as planned…
Starting from a clean install I went about revamping a number of things, as well as keeping on top of the new security measures that have been added to the observatory in the past six months.
I love static sites and have no use for too much dynamic frivolity, which also means I can tighten up security policies so my server is (hopefully) more of a vault with an excellent CCTV system for you all to look inside with. But comments on this blog have been an issue. Disqus has been a necessary evil since this blog's inception, but both my own and the worries of the internets are something that needed tending to.
