All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env | |
# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced | |
# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start | |
# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running. | |
# Add the following to your shell init to set up gpg-agent automatically for every shell | |
if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then | |
source ~/.gnupg/.gpg-agent-info | |
export GPG_AGENT_INFO | |

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.
I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.
Chrome 51 has some pretty wild behaviour related to console.log
in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.
I tried a few different techniques to make a GIF via command-line and the following gives me the best control of quality and size. Once you're all setup, you'll be pumping out GIFs in no time!
Install FFmpeg
Install ImageMagick
UPDATE: You don't need shims anymore! We can just use this now, and eventually it'll even be in Ember core.
app.import()
works with node_modules
now! As of Ember 2.15. Previously it only worked with bower_components
and vendor
.
Docs for app.import
are here:
