YubiKey 4 series GPG and SSH setup guide

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.

You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.

First, install the required software:

Instructions for Windows

Open CMD (windows > run > type "cmd" > enter).
Run geth.exe --dev --ipcpath geth.ipc console

Nested Routers in Express.js

Express makes it easy to nest routes in your routers. But I always had trouble accessing the request object's .params when you had a long URI with multiple parameters and nested routes.

Let's say you're building routes for a website www.music.com. Music is organized into albums with multiple tracks. Users can click to see a track list. Then they can select a single track and see a sub-page about that specific track.

At our application level, we could first have a Router to handle any requests to our albums.

const express = require('express');

First of all, lets understand few date-time standard definitions.

ISO Time String

The standard that we are talking about is formally named ISO 8601:1988 but is popularly also called ISO 8601

ISO 8601 also has support for

years before 0 AD or after 9999
Week based dates
Ordinal dates

A Guide to Rust Syntax

A very brief guide to Rust syntax. It assumes you are already familiar with programming concepts.

This was written in 2014. It is not a good reference for Rust today, though the content is still correct.

cheats.rs looks like a good alternative.

	pragma solidity ^0.4.11;

	contract LinkedList {

	event AddEntry(bytes32 head,uint number,bytes32 name,bytes32 next);

	uint public length = 0;//also used as nonce

	struct Object{
	bytes32 next;

	This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

	usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

	Getting help:
	-h — print basic options
	-h long — print more options
	-h full — print all options (including all format and codec specific options, very long)
