Probably the smallest feature-complete bitcoind RPC interface in existence.
var request = require('request');
function Bitcoind(url) {
this.url = url;
};
Bitcoind.prototype.rpc = function(method, params, callback) {
this.request({jsonrpc: '2.0', method: method, params: params}, callback);
};

Using Ruby to fuck up a file system
```ruby
require 'fileutils'
require 'securerandom'
2_000_000.times do |site|
site_name = SecureRandom.hex[0...20]
puts site_name
Dir.mkdir File.join('./', 'sites', site_name)

How do I make try_files work here..
# So, the idea here is to take USERNAME.neocities.org, and have it serve
# from /home/web/neocities/public/sites/USERNAME/REQUESTED_FILENAME
# When I try to use it, I get in error.log:
# invalid number of arguments in "try_files" directive in /etc/nginx/sites-enabled/neocities:5

Idea for storing an SSN (or CC#, or anything confidential) on a database, preventing an attacker from looking at it if they've compromised the database the encrypted text is in, by hiding the private key on an offline machine, and encrypting the text with the public key (which it theoretically cannot read itself without the private key)
require 'openssl'
public_key = OpenSSL::PKey::RSA.new(File.read('./public.pem'))
cipher = OpenSSL::Cipher::Cipher.new('aes-256-cbc')
cipher.encrypt
cipher.key = random_key = cipher.random_key
cipher.iv = random_iv = cipher.random_iv
encrypted_data = cipher.update('SSN number')
encrypted_data << cipher.final
