CockroachDB and Docker Compose

This is the first in a series of tutorials on CockroachDB and Docker Compose

• Information on CockroachDB can be found here.
• Information on Docker Compose can be found here

1. Install Docker Desktop

Because we already have an official CockroachDB docker image, we will use that in our docker-compose.yml file. We recommend you use one of the current tags instead of latest.

Things that programmers don't know but should

(A book that I might eventually write!)

Gary Bernhardt

I imagine each of these chapters being about 2,000 words, making the whole book about the size of a small novel. For comparison, articles in large papers like the New York Times average about 1,200 words. Each topic gets whatever level of detail I can fit into that space. For simple topics, that's a lot of space: I can probably walk through a very basic, but working, implementation of the IP protocol.

Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

Channel Changes

The channel layer received significant features and an overhaul of the topic abstraction. Upgrade your 0.7.x channels should only require a few simple steps.

Notable changes:

• An updated version of phoenix.js is required, replace your priv/static/js/phoenix.js with https://github.com/phoenixframework/phoenix/blob/v0.8.0/priv/static/js/phoenix.js
• "topic" is now just an identifier. You join topics, broadcast on topics, etc. Channels are are dispatched to based on topic patterns in the router.
• Channel callbacks in 0.8.0 introduce the concept of outgoing events. Prior to 0.8.0, chanenls only processed incoming events via the event/3 callbacks. In 0.8.0, event/3 has been renamed to handle_in/3, and outgoing events callbacks can be defined via handle_out/3
• All channel callbacks, such as join/3, leave/2, handle_in/3, and handle_out/3 now accept the socket as the last argument. This mimicks GenServer APIs
• The return signature of handle_in, `handle_
