Intro

The below is a breakdown / bird's eye view of how a sparse-array backed ECS like EnTT or Shipyard works.

Please see the thanks and references at the bottom - without their help I would not have been able to share this breakdown with you... everything here is really just notes and rephrasing of what they've written already :)

Also, these notes do not cover archetype systems (like unity) nor adaptations of archetypes (like in Flecs). Though there's a couple comparative footnotes at the end.

Here we go!

Setting up Pi Zero OTG - The quick way (No USB keyboard, mouse, HDMI monitor needed)

More details - http://blog.gbaman.info/?p=791

For this method, alongside your Pi Zero, MicroUSB cable and MicroSD card, only an additional computer is required, which can be running Windows (with Bonjour, iTunes or Quicktime installed), Mac OS or Linux (with Avahi Daemon installed, for example Ubuntu has it built in).
1. Flash Raspbian Jessie full or Raspbian Jessie Lite onto the SD card.
2. Once Raspbian is flashed, open up the boot partition (in Windows Explorer, Finder etc) and add to the bottom of the config.txt file dtoverlay=dwc2 on a new line, then save the file.
3. If using a recent release of Jessie (Dec 2016 onwards), then create a new file simply called ssh in the SD card as well. By default SSH i

Bevy Remote Protocol (BRP)

The Bevy Remote Protocol (BRP) is a transport-agnostic and serialization-agnostic protocol for communication between a Bevy application (acting as a server) and a remote (or local) client. It's a request/response-style protocol (similar to HTTP), meaning that every communication is always initiated by the client, and the server only responds to the client's requests.

Example Uses

• A editor/inspector, allowing the user to inspect and modify the Bevy application's state in real time, both locally and remotely;
• “Gameshark“-style cheats, allowing the user to modify a game's state in real time;
• JS/HTML-based UI interacting with an embedded Bevy application running in a browser;
• Non-Bevy/Rust applications (e.g. a C++/Python/Java application) interacting with embedded Bevy modules;

Anchors in Markdown

To create an anchor to a heading in github flavored markdown. Add - characters between each word in the heading and wrap the value in parens (#some-markdown-heading) so your link should look like so:

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.
