python "breakpoint" (more or less equivalent to ruby's binding.pry); for a proper debugger, use https://docs.python.org/3/library/pdb.html

Vim: pushing built-in features beyond their limits

The situation

Searching can be an efficient way to navigate the current buffer.

The first search commands we learn are usually / and ?. These are seriously cool, especially with the incsearch option enabled which lets us keep typing to refine our search pattern. / and ? really shine when all we want is to jump to something we already have our eyeballs on but they are not fit for every situation:

  • when we want to search something that's not directly there, those two commands can make us lose context very quickly,
  • when we need to compare the matches.

SSH Tunneling

Problem

You want to query a DB and get a result set, but you don't have access to that DB directly from your localhost.

  • Bad solution A: Cry
  • Bad solution B: Ask someone who does have access to run your query for you
  • Bad solution C: ssh into a box that has access, then psql into the DB
