Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

Installation

The Ruby Way! (Fun)

On my LAN, I have:

Machine A: An OS X machine running VirtualBox 3.2
Machine B: An OS X machine running VirtualBox 4

Here's what I did:

first, create the image on machine A by running the Palm Emulator application.
open VirtualBox 3.2 on machine A to make sure it set up correctly. Run it and watch it boot. If it works fine, shut it down.
On Machine B, close all VBox VMs that are currently running, and close the VirtualBox application if it is running.

Remove me from this list and please don't contact me again by any means. That means don't e-mail me, don't call me, don't find me at conferences, don't send carrier pigeons to my house with small notes attached to their feet, don't even wave to me in the street if you see me. I'll snub you right there in public and that will be really awkward for you. I can't be held responsible if your friends don't talk to you anymore after that. And no, I don't care how great your position supposedly is, what technology it's using, where it's at, how many celebrities are invested, how close they are to closing funding, how much equity they're offering, how many times Paul Graham has high-fived the founders, how close they are to the Mission in San Francisco, how much the position is paying, how great the company is, who claims they know me that works there, how big their signing bonus is, or who I'll supposedly be working for/with. I'm not interested.

Just once more to be totally clear: don't contact me again. At al

Simple file/stream encryption using OpenSSL

Create and store a 512-byte random encryption key named secret:

$ mkkey secret

Encrypt the contents of file with the secret key and write it to file.enc:

$ encrypt secret < file > file.enc

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

Useful emoji for git commit messages

If you add emoji to your commit messages for a GitHub repo, they become less boring, and you can convey the kind of change you're adding. See the full set of GitHub supported emoji here (also useful for easy copy&paste via a simple click).

The following is a possible scheme to use:

Note: This is an older post that I did back when I thought I might have time to be a blogger. Oh I was oh so wrong. However, it has proven useful for some folks on stackoverflow. Thus I'm keeping it alive here on Gist.

One of my past projects dealt heavily with an open source Apple technology called HTTP Live Streaming. It’s an HTTP based streaming protocol that at its most fundamental level provides a way to stream video and audio from just about any server with nothing but a few free software tools provided by Apple**. However, it has a few additional features that I think make it a really exciting tool. Yet, I haven’t seen HTTP Live Streaming used very much. This is probably mainly due to the combination of a lack of good/clear documentation, and Apple’s Live Streaming Developer Tools being command line based also make the barrier to entry higher than many developers want to deal with.

The hope is to share my understanding of how to use this technology to:

	#!/usr/bin/env ruby

	require 'readline'
	def prompt(prompt="> ")
	input = nil
	prompt += " " unless prompt =~ /\s$/
	loop do
	input = Readline.readline(prompt)
	break if input.length > 0
	end

	define(['require'], function(require) {
	var stubbed = [];
	return {
	stub: function(name, implementation) {
	stubbed.push(name);
	requirejs.undef(name);
	define(name, [], function() {
	return implementation;
	});
	},

	# There was a day where I have too many color schemes in iTerm2 and I want to remove them all.
	# iTerm2 doesn't have "bulk remove" and it was literally painful to delete them one-by-one.

	# iTerm2 save it's preference in ~/Library/Preferences/com.googlecode.iterm2.plist in a binary format
	# What you need to do is basically copy that somewhere, convert to xml and remove color schemes in the xml files.

	$ cd /tmp/
	$ cp ~/Library/Preferences/com.googlecode.iterm2.plist .
	$ plutil -convert xml1 com.googlecode.iterm2.plist
	$ vi com.googlecode.iterm2.plist
