As an Rails dev on OSX, do any tests (or various dev tasks) that spawn a browser work with the WSL? ie. the letter_opener gem will open a sent email in the browser, selenium will run tests in the browser, etc.
What about PostgreSQL? Last time I tried it I had to install it on Windows because of some reason I cannot remember...
I do not use Postgress, I use Firebird SQL and I had no problems installing it in WSL.
