JavaScript code for generating Firebase Push IDs
/**
* Fancy ID generator that creates 20-character string identifiers with the following properties:
*
* 1. They're based on timestamp so that they sort *after* any existing ids.
* 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
* 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
* 4. They're monotonically increasing. Even if you generate more than one in the same timestamp, the
* latter ones will sort after the former ones. We do this by using the previous random bits
* but "incrementing" them by 1 (only in the case of a timestamp collision).

onBlur for entire react element
function OnBlurComponent({ onBlur }) {
const handleBlur = (e) => {
const currentTarget = e.currentTarget;
// Check the newly focused element in the next tick of the event loop
setTimeout(() => {
// Check if the new activeElement is a child of the original container
if (!currentTarget.contains(document.activeElement)) {
// You can invoke a callback or add custom logic here

How to configure multiple deploy keys for different private github repositories on the same computer without using ssh-agent

How to configure multiple deploy keys for different private github repositories on the same computer without using ssh-agent

Let's say alice is a github.com user, with 2 or more private repositories repoN. For this example we'll work with just two repositories named repo1 and repo2

https://github.com/alice/repo1

https://github.com/alice/repo2

You need to be to pull from these repositories without entering a passwords probably on a server, or on multiple servers.

Instructions on how to fix npm if you've installed Node through Homebrew on Mac OS X or Linuxbrew

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
