`assert()` (sometimes called `invariant()`)

Instead of checks like:

if (value === null) {
  throw new Error("missing value")
}
doSomethingThatNeedsValue(value)

Strictly Frameworks

Mobiledoc - github.com/bustle/mobiledoc-kit - framework to build editors with a standardized JSON structure
ShareDB - github.com/share/sharedb - framework to sync any JSON document using operational transforms, add real-time collaborative editing to anything else
Bangle.dev - github.com/bangle-io/bangle.dev - toolkit built for building editors, based on prosemirror

Abstracted Editors

These use separate document structures instead of HTML, some are more modular libraries than full editors

Most VPN Services are Terrible

Short version: I strongly do not recommend using any of these providers. You are, of course, free to use whatever you like. My TL;DR advice: Roll your own and use Algo or Streisand. For messaging & voice, use Signal. For increased anonymity, use Tor for desktop (though recognize that doing so may actually put you at greater risk), and Onion Browser for mobile.

$PATH in MacOSX 10.7

MacOSX has a truly global path setting that precedes any other setting like ~/.bash_profile. The file /private/etc/paths is a list of pathnames. The order from top to bottom defines the resulting order in the $PATH variable. After loading /private/etc/paths there is a directory /private/etc/paths.d/ with files in the same style. Those are appended to the $PATH variable.

The default content of /private/etc/paths looks like this:

/usr/bin

/bin

	pragma solidity ^0.7.0;

	library bytesSwap {

	function bytes32ToString(bytes32 _bytes32) public pure returns (string memory) {
	uint8 i = 0;
	while(i < 32 && _bytes32[i] != 0) {
	i++;
	}
	bytes memory bytesArray = new bytes(i);

	/**
	* 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).
