When I was growing up, my grandfather had a shed in his garden. He would spend hours in there, making and fixing things. This was way before we had the internet, so I spent a lot of time studying him creating things in that shed. Although the shed was full of many tools, from drills to lathes to electrical gubbins and lots of things I doubt I could identify even today, he made use of only a tiny subset of what he had at hand. Yet there never seemed to be limits to what he could achieve.

Make Lua development easy with Luarocks
Bash too basic? Too much whitespace in Python? Go too corporate?

A framework for building products from open source projects
My first memory of playing with a computer was through an MS-DOS terminal on the x86 PC in my grandfather's pharmaceutical research lab in the early '90s—playing games stored on 3.5" floppy disks and doing touch-typing exercises. As technology improved, I spent an obscene amount of time taking my computer apart to add more RAM, a new graphics card, or a new fan, mostly so I could play cooler games. It was a fun, ongoing project, and I bonded with my father over it. It was also way cheaper than buying a new computer.
