I published a free online code testing tool (like Codility / HackerRank) if anyone is interested. I hire a lot of software devs as part of my job. I wanted to screen them with some basic 10 minute tests before doing a full interview. Something like reversing a list or FizzBuzz type stuff. Existing tools are pretty expensive to send lots of candidates through and I really didn't need all the bells and whistles, so I just wrote my own very basic Python one a little while back. I decide to polish it up a bit and release it for others that might need it.
It currently supports Python, Javascript, Ruby, and Java. If anyone is interested it's at https://codetester.io/
