ASUS makes a pretty handy Chromebox, and it's handy not just because it's running ChromeOS, it's handy because of everything you can do to the box itself.

The ASUS Chromebox is easily upgradeable, and capable of running just about any linux distribution.

The model I picked up, the M004U has the following specs:

Celeron 2955U (1.4GHz) 64 bit Dual core processor with 2MB L3 Cache
2GB DDR3 1600 RAM with 2 slots
16GB SSD HDD
802.11 b/g/n dual-band wireless, Bluetooth 4.0, and gigabit ethernet

Mac OS X 10.11 El Capitan

Custom recipe to get OS X 10.11 El Capitan running from scratch, setup applications and developer environment. This is very similar (and currently mostly the same) as my 10.10 Yosemite setup recipe (as found on this gist https://gist.github.com/kevinelliott/0726211d17020a6abc1f). Note that I expect this to change significantly as I install El Capitan several times.

I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.

This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.

You are encouraged to fork this and modify it to your heart's content to match your own needs.

Using Homebrew to manage Node.js and io.js installs on OSX

Having both Node.js and io.js installed with NVM was giving me a load of problems, mainly with npm. So I uninstalled NVM and manage Node.js and io.js with homebrew.
Heres how.

Install Node.js and io.js

$ brew install node
$ brew install iojs

Tutum Zero Downtime Re-deploy

I tweeted Tutum last night asking if they're looking at implementing zero downtime re-deploys for a given service. Slightly surprised by their response as it seems like a critical feature if you want to use the service for a production environment.

"not a top priority, but by Spring :)"

As Tutum currently doesn't support graceful termination of containers within a service, I was experiencing a 5-10 second window of 503 errors, so decided to use the following hack (code below) until the feature is officially implemented.

	For nginx,

	location ~* \.(eot\|ttf\|woff)$ {
	add_header Access-Control-Allow-Origin *;
	}

	Or better way inside virtual host location use,

	Inside location use
	if ($request_filename ~* ^.?/([^/]?)$)
