TIL – Elixir can keep config settings from one run to another. I was reading from the shell environment in config.exs and running export foo=”bar” wasn’t being picked up from one run to the next. Once I moved reading the environment variable out of config, it worked consistently.
I needed a Riak install separate from existing projects’ installations to work on a new project. I ran into some trouble. OSX keeps changing the way it handles configurations like maximum open files, so existing doc was out-of-date.
