Once upon a time there was a user that wanted to install firefox.

The user tried to do pacman -S firefox but it didn't work. The all mighty pacman reported that firefox-3.2.4-1.i686.pkg.tar.gz could not be found on his mirror. So the user tried pacman -Sy firefox. It worked and the user rejoiced since he could once again go and troll /h/.

But all was not good. The user had made a grave error!

See, when the user told the almighty pacman to -Sy firefox, pacman did

What forces layout / reflow

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.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.

Conceptual Model

At the moment GraphQL allows 2 types of queries:

• query
• mutation

Reference implementation also adds the third type: subscription. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.
