Git sees every file in your working copy as one of three things:

tracked - a file which has been previously staged or committed;
untracked - a file which has not been staged or committed; or
ignored - a file which Git has been explicitly told to ignore.

Ignored files are usually build artifacts and machine generated files that can be derived from your repository source or should otherwise not be committed. Some common examples are:

dependency caches, such as the contents of /node_modules or /packages
compiled code, such as .o, .pyc, and .class files

The code examples and direct quotes are all from Raymond's talk. I've reproduced them here for my own edification and the hopes that others will find them as handy as I have!

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

Intro

Normally the Jetbrains applications store their config and system in a directory in your home directory. That's fine except when you run out of space in your home directory, or they change the directory with an upgrade. For example, when you upgrade PhpStorm from 2016.3 to 2017.1, the config directory and systems directory changes as well. This means that 2017.1 doesn't have the plugins you installed with 2016.3

Somewhere buried deep in the knowledge base is an article that explains how you can fix this but putting it out here makes it easier to find.

Instructions

These instructions are written for Ubuntu, if you run another distro the locations and files might be different.

I'm assuming you config and system directory will be stored in /d1/config/{JetBrains App}/

Context managers

In Python, a context manager is an object that can be used in a with statement. Here's a context manager that reports the total wall-clock time spent inside a with block:

import time

class Timer(object):
    def __init__(self, msg):
        self._msg = msg

	# Basic Makefile for Golang project
	# Includes GRPC Gateway, Protocol Buffers
	SERVICE ?= $(shell basename `go list`)
	VERSION ?= $(shell git describe --tags --always --dirty --match=v* 2> /dev/null \|\| cat $(PWD)/.version 2> /dev/null \|\| echo v0)
	PACKAGE ?= $(shell go list)
	PACKAGES ?= $(shell go list ./...)
	FILES ?= $(shell find . -type f -name '.go' -not -path "./vendor/")

	# Binaries

	const http = require('http');
	const server = http.createServer();

	server.on('request', (request, response) => {
	let body = [];
	request.on('data', (chunk) => {
	body.push(chunk);
	}).on('end', () => {
	body = Buffer.concat(body).toString();

	# import config.
	# You can change the default config with `make cnf="config_special.env" build`
	cnf ?= config.env
