Work in progress, I'll write this up properly when I'm done.

Almost all credit goes to @maxogden for putting me on to this and pointing me in the right direction for each of these items.

Prerequisites:

• Raspberry Pi
• Kindle Paperwhite freed from its locked down state (jailbroken) http://www.mobileread.com/forums/showthread.php?t=198446
  • You have to downgrade your Kindle to 5.3.1 to install the current jailbreak; that's just a matter of getting the old version image, putting it on your Kindle via USB and telling it to install "upgrade". Then you put in the Jailbreak files, load the ebook and break.
• Your kindle will be quick to detect an upgrade is available so it'll want to upgrade soon afterwards but the jailbreak will last but you have to reinstall the developer certificates so it's a bit of a pain but doable. Find all the instructions on the mobileread.com forums and wiki.

In addition to awesome docs #228, Bower deserves a proper logo. See below for sketches. I'm curious if you think any of these are worth me putting more effort into.

Take a look at Yeoman right now.

The other two entities have awesome logos. Bower's got to represent.

Why I Like Go

I visited with PagerDuty yesterday for a little Friday beer and pizza. While there I got started talking about Go. I was asked by Alex, their CEO, why I liked it. Several other people have asked me the same question recently, so I figured it was worth posting.

Goroutines

The first 1/2 of Go's concurrency story. Lightweight, concurrent function execution. You can spawn tons of these if needed and the Go runtime multiplexes them onto the configured number of CPUs/Threads as needed. They start with a super small stack that can grow (and shrink) via dynamic allocation (and freeing). They are as simple as go f(x), where f() is a function.
