Background

One of the biggest missed opportunities thus far with HTTP/2 ("H/2") is that we are not yet able to sunset WebSockets in favor of H/2. Web Sockets and H/2 both support multiplexing messages bi-directionally and can send both textual and binary data.

Server Sent Events ("SSE"), by contrast, are not bi-directional (they're a "server-push-only" channel) and binary data cannot be sent easily. They are, however, very simple to implement. Adding to the menagerie of options, RTCPeerConnection can also be used to signal data to applications in a low-latency (but potentially lossy) way.

Because H/2 [does not support the handshake (upgrade) that WebSockets use to negotiate a connection](https://daniel.haxx.se/blog/2016/06/15/no-websockets-

How to Change Open Files Limit on OS X and macOS

This text is the section about OS X Yosemite (which also works for macOS Sierra) from https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/#mac-os-x

The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/

Mac OS X

To check the current limits on your Mac OS X system, run:

state-machine-component

A tiny (265 byte) utility to create state machine components using two pure functions.

🔥 JSFiddle Demo

Usage

The API is a single function that accepts 2 pure functions as arguments:

	// add this please
	// add this please
	require("preact-cli/lib/lib/webpack/polyfills");
	// look above

	import { h } from "preact";
	import habitat from "preact-habitat";

	import Widget from "./components/hello-world";
