Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

• charAt(pos: number): string ^ES1

  Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

Let's Encrypt on Ubuntu 14.04, nginx with webroot auth

This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt.

As it is not possible to change the ports used for the standalone authenticator and I already have a nginx running on port 80/443, I opted to use the webroot method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com and example.com).

Configuration

For this, I placed config files into etc/letsencrypt/configs, named after <domain>.conf. The files are simple:

v0lkan

user web;

# One worker process per CPU core.
worker_processes 8;

# Also set
# /etc/security/limits.conf
#   web soft nofile 65535
#   web hard nofile 65535
# /etc/default/nginx

    filter: blur(3px);

from uuid import UUID

def validate_uuid4(uuid_string):

    """
    Validate that a UUID string is in
    fact a valid uuid4.

    Happily, the uuid module does the actual
    checking for us.

Stylus Mixin for Linear Gradients

A Stylus mixin for linear gradients with support for comma-separated splat arguments. In part created as a work-around / abstraction for this.

The method for retrieving the fall-back background colour can do with some improvement, such as averaging the colours or selecting a colour by means of passing an additional argument.
