You can think loosely of channels like pipes for fluid - pour it in one end and out at the other.

By including the arrow <- chan or chan <-, you are achieving three things:

You are making it clear that the parameter is one end of a channel.
You are expressing clearly which end is being supplied.
You are giving more information to the compiler for checking. If the function body tries to use the wrong end of the channel, the compiler can raise an error. These are good reasons to show the channel end whenever possible.

| when you see | which end is of the channel is it for? |

Hi Steve,

You go to APIs and Services > Credentials in the console and you can either take one of the keys that are already there or you can create a new one with the "Create Credentials" button. This is the only way to create API keys, but they can be reused any amount of times. There is a feature request to create them with a gcloud command, however. You can follow it here if you're interested. https://issuetracker.google.com/76227920

Let me know if you have any other questions or concerns and I'll be happy to help.

Cheers!

Table tops (BYO Fixed Legs)

The cheapest way to go is to get a table top and some fixed legs. Pick sitting or standing heigh, and then never change it.

Ikea Table tops	Dimensions	Price
Ikea Bekant oak veneer	47 1/4x31 1/2 "	$80
Ikea Bekant oak veneer	55 1/8x23 5/8 "	$90
Ikea Bekant oak veneer	63x31.5"	$100
Ikea Gerton beech	61x29.5"	$100

From Go: Format a time or date

Consider just running dateparse:

go get -u github.com/araddon/dateparse/dateparse
dateparse --timezone="UTC" "2019-11-20T22:32:59.882Z"
dateparse --timezone="America/Detroit" "2017-07-19 03:21:00"

From https://medium.com/@ribice/serve-swaggerui-within-your-golang-application-5486748a5ed4

SwaggerUI can be downloaded from their GitHub Repo Releases page. Once downloaded, place the contents of dist folder somewhere in your Go project. For example, swaggerui. After that, also move your openapi.json or swagger.json file to swaggerui folder (or whatever you called it), and inside index.html change url to ./swagger.json (e.g. url: "./swagger.json").

Serve using net/http

fs := http.FileServer(http.Dir("./swaggerui"))
http.Handle("/swaggerui/", http.StripPrefix("/swaggerui/", fs))

Information in this Gist originally from this github issue, which is outdated.

As @RomanMinkin mentioned, you can also consider Casbin (https://github.com/casbin/casbin). It is the most starred authorization library in Golang. There are several differences between Casbin and OPA.

Feature	Casbin	OPA
Library or service?	Library/Service	Library/Service
How to write policy?	Two parts: model and policy. Model is general authorization logic. Policy is concrete policy rule.	A single part: Rego
RBAC hierarchy	Casbin supports role hierarchy (a role can have a sub-role)	Role hierarchies can be encoded in data. Also with the new `graph.reachable()` built-in function queries over those hierarchies are much more feasible now.
RBAC separation of duties	Not supported	Supported: two roles cannot be assigned together

What's the diff between phabricator and github?

Phabricator’s and github’s usage of git is very different. With github you are always pushing new commits, but with phabricator you should never push (except when updating a deploy branch from master). You are better off pretending that we don't actually use git, and that the Khan Academy recommended Phabricator workflow is a series of inscrutable magic incantations that must be meticulously performed or you'll release Ẕ̶̨̫̹̌͊͌͑͊̕͢͟a̡̜̦̝͓͇͗̉̆̂͋̏͗̍ͅl̡̛̝͍̅͆̎̊̇̕͜͢ģ̧̧͍͓̜̲͖̹̂͋̆̃̑͗̋͌̊̏ͅǫ̷̧͓̣͚̞̣̋̂̑̊̂̀̿̀̚͟͠ͅ.

If you are still irrationally stubborn, like I am, and really want to continue using the familiar and universal-outside-khan git workflow, then since you will be fighting the Khan tools you need to be firm and unambiguous in communicating to phabricator what you want it to do.

My workflow is always:

Make a branch.
Make some changes
