Introduction

ccache is a compiler cache. It speeds up recompilation of C/C++ code by caching previous compilations and detecting when the same compilation is being done again. This often results in a significant speedup in common compilations, especially when switching between branches. This page is about using ccache on Mac with clang and ninja build system. If you want to use Xcode, please refer to the old CCacheMac page.

In order to use ccache with clang, you need to use the current git HEAD, since the most recent version (3.1.9) doesn't contain the patch needed for using chromium style plugin.

Installation

To install ccache with [homebrew](http://mxcl.

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

Hardening the USB Armory

As a good crypto nerd, I usually use an entirely encrypted linux FS: / but also /boot using grub LUKS support. It's a good setup but it's not perfect, the BIOS and the bootloader are not protected.

I recently got a USBArmory and I wanted to apply the same (or a better) setup.

I found some useful links but no clear howto. So this is my setup.

	#!/usr/bin/env ruby

	## disconnect

	# ./disconnect.rb -u yourusername [-o /your/path] [-p yourhttpproxyserver]
	#
	# This is a command-line utility for the bulk-downloading of run data from
	# the connect.garmin.com web application, which has lackluster export
	# capabilities.
