Indent Code and Lists by 4 Spaces in Emacs Markdown Mode
I noticed that my Emacs didn't maintain the current line's indentation when editing code blocks in Markdown (markdown-mode). I indent the first line with 4 spaces like any sane person would. When I hit enter to continue in the next line, thanks to the markdown-mode defaults, I am presented with a new line that's properly indented visually. Only when committing to git did I notice that Emacs inserted tabs instead of spaces. Gasp!
Global TODO Capture Hotkey for Emacs Org Mode on macOS
I am using GNU Emacs for a while now to do all kinds of stuff. I'm thinking about migrating away from OmniFocus as my task manager and use Org mode instead. What I like so far is the free-form list nature of Org files. I can have an outline of notes and sprinkle TODO items inside them. This way I can take notes on puzzling problems I'm working on and mark things I need to do later. This is super useful to remind myself what to clean up before a commit, for example write or amend tests or remove debug code somewhere. I like it. I got used to a lot of shortcuts already, so most of the pain of daily use is gone.
