Recently I wanted to enable debug level logging of chef-solo runs in a vagrant box. As it turns out there are two ways to do this and both appear to be undocumented:
Vagrant.configure("2") do |config| # ... config.vm.provision :chef_solo do |chef| chef.arguments = '-l debug' # ... end endVagrant.configure("2") do |config| # ... config.vm.provision :chef_solo do |chef| chef.log_level = :debug # ... end end

Adafruit has a great LCD+Keypad kit for the Raspberry Pi with excellent assembly instructions and a nice Python library. I just had to order one along with my first Raspberry Pi.
After it arrived I picked up a 25W Radioshack Pro-Line soldering iron, some 60/40 rosin-core solder and got to work. Luckily I had an old, dead iPod mini to tear apart and practice on. After soldering the first dozen points I felt like I was getting the hang of it. All-in-all I think it came out pretty well.
I just switched to the default WordPress theme Twenty Twelve because my old theme was dated and not mobile-friendly.
Why the default theme?
Most free WordPress themes suck. They are displeasing to the eye, bloated, and just too ”bloggy”. I want a modern, responsive, theme that complements my content. Why is the WordPress community still failing to grasp these concepts? (For the record, “premium” themes also fall short.)
I can’t wait for Ghost. Hopefully its community truly appreciates the concepts that make it a great blogging platform.
Apache mod_rewrite is incredibly powerful but it’s also a PITA if you’re trying to do something advanced. Luckily, you can log mod_rewrite’s activities and better understand why your rules aren’t working.
Just add RewriteLogLevel and RewriteLog to your Apache VirtualHost config:
<VirtualHost *:80> # ... RewriteLogLevel 8 RewriteLog /var/log/apache2/rewrite.log # ... </VirtualHost>
I suggest log level 8 but you can try lower. Logging rewrites will be SLOW: do not enable in production.
Sample rewrite log output:
[perdir /var/www/local.dev/www/] RewriteCond: input='/small/asdfsadf/avatar.jpg' pattern='^(.*)/(.*)/(.*)' => matched [perdir /var/www/local.dev/www/] RewriteCond: input='/var/www/local.dev/www/small/avatar.jpg' pattern='-f' => matched [perdir /var/www/local.dev/www/] rewrite 'small/asdfsadf/avatar.jpg' -> '/small/avatar.jpg' [perdir /var/www/local.dev/www/] internal redirect with /small/avatar.jpg [INTERNAL REDIRECT]

JSON.stringify is pretty cool, in fact you can use it to print javascript data structures in a more readable format.
Of course modern browser javascript consoles already format nested data for you, but this is really helpful when using console.log() in Node.js
console.log(JSON.stringify(window.location, null, 2));
// prints...
