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.

Today I get an alarm that a customer's website isn't responding. This particular customer isn't an American customer, and due to international law their server has to be hosted in their own country. So they picked a hosting company over there and we shipped their servers to the hosting company.

Traceroute showed that we could get to the city where they were hosted, but not the server itself. I called the hosting company's support line. After explaining to them that my boss had...

assert(technology != magic);

Posted 08-12-2011 at 12:37 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

Some years ago I happened upon an uncomfortable truth regarding source code. I happened to be programming in an interpreted language (the only language I knew when I was 8 years old), and I made the unfortunate realization that without the interpreter, my code was useless. Somehow that seemed disheartening to me, so I vowed I would learn everything there was to know about computers. I vowed that I would understand the machine.

I didn't really know where to turn (I didn't have any...

Book Collection

Updated 10-26-2013 at 09:26 PM by rocket357 (Update books I own)

I've been busy assembling a good library of computing books (stuff that directly interests me, of course...so you won't find Java or such in this list), and I would like to get some input (in the event I've overlooked critical "must-have" books). I don't own all of these (yet), but I've been buying them left and right as I can afford it (I usually buy one or two each payperiod, used on Amazon...as long as the book is readable and not too banged up, I'm game). The (not-yet-complete) list...

I've started development on my own operating system. I've achieved "hello world OS" status so far (boots up and prints a message to the console), and I've started working on core functions within the kernel to make actual kernel development easier.

So I'm going to use this space as something of a progress update as I go. Who knows, perhaps one day some of the crazy ideas I have on OS design will come to light.

Time will tell.

vpnc auto-reconnect script

Posted 07-14-2011 at 02:05 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

A native Cisco VPN client doesn't exist for OpenBSD, so I wrote this little script to make vpnc more useful. It detects when the vpn tunnel fails and re-establishes it.

Code:
#!/bin/ksh

# This script was developed on OpenBSD with ksh as the primary shell.

# set INT_SERVER to a list of 5 ping-able machines behind your vpn gateway
# ip addresses can be repeated if you have less than five machines.
set -A INT_SERVER 192.168.1.16 192.168.1.201
