Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

A "quick and dirty" random password generator that I see a lot of people use is a construct similar to the following:

dd if=/dev/urandom of=/dev/stdout bs=6 count=1 2>/dev/null | base64

This produces output such as the following:

0zdQE0WC

Or perhaps even:

Pg7Ub+Rx

base64 is an encoding scheme that "converts" binary data into text data using 64 characters. The 64 characters chosen vary...

Shut up and Hack

Posted 06-27-2014 at 01:06 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I'm nearly 75% through a bottle of Merlot, so this blog post may not be here tomorrow afternoon after I sober up a bit and get a chance to read it. Suffice it to say this won't be one of my typical technically-inclined posts.

I read something tonight that bothered me. I happened upon a brilliantly written blog about a young woman's struggle for finding her self worth and her identity. It brought tears to my eyes as I read through her setbacks, her victories, and eventual vindication....

Shifting Gears (take 2)

If you follow my blog you'll know that a few months ago I said goodbye to my Linux Engineering position at Rackspace and joined Amazon Web Services as an AWS Support Engineer. It's been long enough that I feel I have my feet on the ground and I am qualified to give a status update.

Holy crap, Amazon. Go big or go home, they say. I'd love to give some cliche' about "if you work at Amazon you've already gone big", but I'm not even certain I could say that. The problems...

Lessons Learned, Applied

I decided to take the move to Seattle as an opportunity to completely rebuild my home network and harden/update/reinforce particular areas I felt needed attention in my last configuration. A fresh install of OpenBSD-5.5 ensured that nothing from the old configuration remained (partially because I upgraded to a larger CF card, and partially because I just felt like cleaning house completely).

First off, I had a single port that was trunked to the switch, with multiple vlans running...

Bought a beaglebone black.

And a bunch of LEDs, resistors, jumpers and a breadboard. Time for a little fun.

Installed OpenBSD-5.5 on the beaglebone (tried running CURRENT...ouch. Compiling on this thing hurts because the sd card is so incredibly slow...probably my fault, as I used a cheap class 4 micro sd...).

Wired up a simple circuit and started gpioctl'ing pins. Hrmmm. Nothing works. Perform OpenBSD-project problem remediation:
