Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

A Typical directory structure for running tests using `unittest`

Ref : stackoverflow

The best solution in my opinion is to use the unittest [command line interface][1] which will add the directory to the sys.path so you don't have to (done in the TestLoader class).

For example for a directory structure like this:

new_project

├── antigravity.py

git commit stats

Commands to get commit statistics for a Git repository from the command line -
using git log, git shortlog and friends.

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Emacs Survival Guide

Notation

C for Control key (also labeled as CTL or CTRL on keyboards)

M for Meta key (also labeled as EDIT, ALT or COMMAND on keyboards)

if your keyboard doesn't have this key, just press and release ESC for the same purpose.

C- means hold the Control key while typing the key chr.

psql: FATAL: Peer authentication failed for user “postgres” (or any user)

The connection failed because by default psql connects over UNIX sockets using peer authentication, that requires the current UNIX user to have the same user name as psql. So you will have to create the UNIX user postgres and then login as postgres or use sudo -u postgres psql database-name for accessing the database (and psql should not ask for a password).

If you cannot or do not want to create the UNIX user, like if you just want to connect to your database for ad hoc queries, forcing a socket connection using psql --host=localhost --dbname=database-name --username=postgres (as pointed out by @meyerson answer) will solve your immediate problem.

But if you intend to force password authentication over Unix sockets instead of the peer method, try changing the following pg_hba.conf* line:

	# Configure homebrew permissions to allow multiple users on MAC OSX.
	# Any user from the admin group will be able to manage the homebrew and cask installation on the machine.

	# allow admins to manage homebrew's local install directory
	chgrp -R admin /usr/local
	chmod -R g+w /usr/local

	# allow admins to homebrew's local cache of formulae and source files
	chgrp -R admin /Library/Caches/Homebrew

	'use strict';

	class NameCard extends HTMLElement {
	set name(val) {
	this._name = val;

	this.render();
	}
	get name() {
	return this._name;

	class PubSub {
	constructor() {
	this.handlers = [];
	}

	subscribe(event, handler, context) {
	if (typeof context === 'undefined') {
	context = handler;
	}
