tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

type z
type 'a s

(* Sadly enough, without kind restrictions, this still allows nonsense types like *)
type nonsense = int s
(* GHC 7.6 supports this (lifting types to kinds & kind constraints) ;-) *)

type (_, _) llist =
  | Nil : (z, 'a) llist
  | Cons : ('a * ('l, 'a) llist) -> ('l s, 'a) llist

// There are four main design concerns here:
// * The API should abstract only DOM manipulations 
//   — law of Do Just One Thing.
// * The API should not allow plugins modifying jQuery,
//   these should be distinct modules/objects 
//   — law of Modularity.
// * The API should not use the DOM as a data model,
//   because this makes all operations inherently slow
//   — law of Orthogonality.
// * The API should be simple, consistent and easy to use

Grab ffmpeg from https://www.ffmpeg.org/download.html

It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.

The most trivial operation would be converting gifs:

ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm

• -crf values can go from 4 to 63. Lower values mean better quality.
• -b:v is the maximum allowed bitrate. Higher means better quality.
