Hack Reactor - Week 2 Day 1

Week 2 has begun. The energy still remains high throughout the cohort.

Today we started a new sprint focused on sub classes and pseudo classical instantiation. We also had the first of many student presentations on various topics. Today’s was given by a senior and was about anti-bodies. Needless to say this was over my head, but an interesting part of the curriculum nevertheless.

Highlights of the day:

  • Keyboard shortcuts
  • Keyboard shortcuts
  • Keyboard shortcuts
  • Permutations

Keyboard shortcuts

Wow, just wow! I knew I was missing out on a lot of power, but Josh Wyatt blew me away. He showed us tons of great tips for Sublime, Bash, Chrome, and more. Just a great, great lecture. To top it off, it was a bonus. Not on the curriculum. Hack Reactor is so great!


Had a great discussion about permutations with cohortmate, Neil Lokare. It started by discussing one of the extra credit problems from the prior sprint. Basically, given a set of letters, how do you identify all the valid words. My pair, Eric Benson, and I tried to do this recursively. Neil got it to work using a permutation library, but there were some errors. It seems that there isn’t a good library to do this.

The more we talked about it, the more interested I became. I love hard problems and trying to reason through a solution. This one is no different. Perhaps this will be something we work on to get a good library published.
