How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

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:

SleepWalker

var touchstartX = 0;
var touchstartY = 0;
var touchendX = 0;
var touchendY = 0;

var gesuredZone = document.getElementById('gesuredZone');

gesuredZone.addEventListener('touchstart', function(event) {
    touchstartX = event.screenX;
    touchstartY = event.screenY;

Secure sessions are easy, but not very well documented.  
Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

The desired configuration for using NginX as an SSL proxy is to offload SSL processing 
and to put a hardened web server in front of your Node.js application, like:

[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]

Edit for express 4.X and >:  Express no longer uses Connect as its middleware framework, it implements its own now.

If you're not familiar: What is fail2ban? fail2ban is an awesome linux service/monitor that scans log files (e.g. auth.log for SSH) for potentially malicious behavior. Once fail2ban is tripped it will ban users for a specified duration by adding rules to Iptables. If you're unfamiliar with fail2ban Chris Fidao has a wonderful (& free!) series about security including setting up fail2ban here.

Recently Laravel released a new feature in 5.1 to throttle authentication attempts by simply adding a trait to your authentication controller. The Laravel throttle trait uses the inputted username, and IP address to throttle attempts. I love seeing this added to a framework out of the box, but what about some of our other apps not built on Laravel? Like a WordPress login? Or even an open API etc.? Ultimately,

Setting up p4merge as diff and merge tool on Windows. Tried for Git version 1.8.4.msysgit.0.

Two alternatives are explained: using the command line, and directly editing the config file.

Setting up from the command line

Being the installation path "C:Program Files\Perforce\p4merge.exe", just run:

$ git config --global diff.tool p4merge
