Using a Yubikey 4 on Windows

These are my notes on how to set up GPG with the private key stored on the hardware Yubikey. This will reduce the chances of your GPG private key from being stolen, and also allow you to protect other secrets such as SSH private keys.

It's just some notes and a partial worklog for now, but I may turn it into a full blog post later.

The polybar package has been updated so this is no longer needed.

Add the following chunk to your existing ISC dhcpd.conf file.

if exists user-class and ( option user-class = "iPXE" ) {
    filename "http://boot.smidsrod.lan/boot.ipxe";
}
else {
    filename "undionly.kpxe";

####Disabling SPI write protection

Put the Chromebook in developer-mode:

• With machine powered off, hold down Esc and Refresh(F3) while hitting power button
• At warning prompt, hit Control+D, then Enter at prompt about enabling developer mode
• Machine will format itself

Now remove the write-protect screw to enable flashrom to flash new Coreboot/Libreboot.

Flip powered-off machine over and remove 8 philips-head screws. 2 are located under rubber feet.

Apache Mesos Build scripts

The Getting started instructions are a good start (no surprise there!) but are somewhat incomplete and currently look a bit outdated (I plan to fix them soon): however, the outcome has been that I have struggled more than I felt necessary in building and running Mesos on a dev VM (Ubuntu 14.04 running under VirtualBox).

Some of the issue seem to arise from the unfortunate combination of Mesos Master trying to guess its own IP address, the VM being (obviously) non-DNS resolvable and, eventually, the Slave and the Framework failing to properly communicate with the Master.

In the process of solving this, I ended up automating all the dependencies installation, building and running the framework; I have then broken it down into the following modules to make it easier to run only parts of the process.
