tldr: Assume you want to quickly jump down 30 lines. You could reach to press ‘3’ then ‘0’ followed by ‘j’ <30j>. However, I prefer to hit ‘3’, ‘3’ then ‘j’ followed immediately by ‘3’ and ‘k’ <33j3k>. It’s 2 more keystrokes, but I can make them faster than I can reach up for ‘3’ then ‘0’ and get back to home row.

• This talk is a bit dated, but the lessons about using what you already know to learn something you want to know are timeless
• Johnny does a good job walking through a large swath of the elixir universe as of 2013 in a short amount of time
• Johnny’s talk can be found here

tldr

• The future is functional
• Elixir is a functional language built on top of Erlang
• Elixir (thanks to Erlang and OTP) has already “solved” concurrency
• Dave’s talk

I love a good conference talk and currently I am really into the Elixir Programming Language. One thing though is it’s tough to know which talks to watch online:

• Some have great presenters, but cover a topic I am not currently interested in
• Some are about a topic relevent to what I’m interested in or need to learn, but the video is poor quality
• Some just aren’t that good

tldr If your shell prompt looks fine in iTerm2, but strange inside emacs shell (specifically, seeing '1337;Remote Host...CurrentDir' inside ansi-term or multi-term) try deleting your iterm-shell-integration file. (see applicable links at bottom of this post)

tldr: The fzf plugin for vim is an absolute game-changer. Some things to try:

• :Files: fuzzy-find (very fast) files in your project
• :GFiles: fuzzy-find the files in your project that are under version control
• :Buffers: like :ls but you can again use fizzy-find
• :Lines: search you project by line of code
• :BLines: like above but limited to current buffer’s contents
• :Tags: yup, fuzzy-find for ctags
• :BTags: yup, it’s what you think

tldr: If you’re using universal-ctags and want elixir support:

• navigate to, or create, ~/.ctags.d
• inside, create elixir.ctags file
• copy and paste the contents of the elixir-ctags file into ~/.ctags.d/elixir.ctags.
• run ctags -R in your project directory
