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

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

GitHub Pain Points

This is my feedback on using GitHub to manage a popular project (ESLint). Topics are presented in no particular order. In general, everything I say about issues also refers to pull requests.

For each problem I've suggested a solution. I realize that actually building out a solution is a complex process and my suggestions do not reach the level of detail sufficient for implementation purposes. It's just to give you an idea of the direction I'm thinking.

Problem: No good way to distinguish new issues from "accepted" issues

Users are opening new issues every day, and these issues automatically bubble to the top of the issues list by default. We do label issues that we're committed to doing as "accepted", but if there are enough new issues, you don't even see those until the second page of issues. Why is this a problem? In a word: distraction.
