Some useful Git aliases that I use every day
#
# Working with branches
#
# Get the current branch name (not so useful in itself, but used in
# other aliases)
branch-name = "!git rev-parse --abbrev-ref HEAD"
# Push the current branch to the remote "origin", and set it to track
# the upstream branch
publish = "!git push -u origin $(git branch-name)"
# From https://raw.github.com/chrishunt/dot-files/master/.tmux.conf

Git Submodules basic explanation

Git Submodules - Basic Explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a sub-repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

  • Separate big codebases into multiple repositories.

Hexadecimal color code for transparency

Hexadecimal color code for transparency

Twitter

How to set transparency with hex value ?

For example, you want to set 40% alpha transparence to #000000 (black color), you need to add 66 like this #66000000.

Enable tab completion for JSX with Emmet in Atom

Enable tab completion for JSX with Emmet in Atom

This guide assumes you have the emmet and language-babel packages already installed in Atom

Gif of the tab completion working

  1. Open the keymap.cson file by clicking on Atom -> Keymap… in the menu bar
  2. Add these lines of code to your keymap:
'atom-text-editor[data-grammar~="jsx"]:not([mini])':

Top-level `await` is a footgun

Edit — February 2019

This gist had a far larger impact than I imagined it would, and apparently people are still finding it, so a quick update:

  • TC39 is currently moving forward with a slightly different version of TLA, referred to as 'variant B', in which a module with TLA doesn't block sibling execution. This vastly reduces the danger of parallelizable work happening in serial and thereby delaying startup, which was the concern that motivated me to write this gist
  • In the wild, we're seeing (async main(){...}()) as a substitute for TLA. This completely eliminates the blocking problem (yay!) but it's less powerful, and harder to statically analyse (boo). In other words the lack of TLA is causing real problems
  • Therefore, a version of TLA that solves the original issue is a valuable addition to the language, and I'm in full support of the current proposal, which you can read here.

I'll leave the rest of this document unedited, for archaeological
