A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

ruby-1.9.3-p392 cumulative performance patch for rbenv

(I guarantee nothing. No warranty I am not responsible blah blah blah. Seems to work great for me so far. Thanks to Tyler Bird who I forked this from.)

This installs a patched ruby 1.9.3-p392 with the railsexpress patchsets: https://github.com/skaes/rvm-patchsets

Stealth Addresses, Transactions and Messages

Normal bitcoin addresses cannot be published in public without losing all privacy, since all transactions to that address can be seen by anybody. Stealth addresses let us publish an address in public which can be used by payers to derive a new address that the payee has access to, but no one else knows is associated with the stealth address. The trick is that the payer must use a nonce to derive the address paid to, and this nonce must be delivered to the payee so they know how to recover the funds. This nonce can be delivered in the transaction, so that no separate channel is required to communicate the nonce.

The same technology can also be used to construct new public keys to send encrypted messages to.

We will discuss four methods:

The simplest form of stealth addresses, which has some drawbacks that can improved upon.

O(1) Block Propagation

The problem

Bitcoin miners want their newly-found blocks to propagate across the network as quickly as possible, because every millisecond of delay increases the chances that another block, found at about the same time, wins the "block race."
