Custom HA Uplink

Zocalo coffee shop migrated to digital registers with a solution from square. While these devices are able to process transactions off-line, some types of transactions need the square registers to be on-line. At the time the coffee shop had only one up-link provided by Comcast. Comcast was providing good service at the time, but with the increased demand for the registers to be on-line they needed higher availability.

Smart Shack

I live in a a really nice cottage behind the house of my roommates. When I moved in a lot needed to be done to modernize and I took the opportunity to learn more about general construction, electrical installations, and industrial wiring concepts.

Linux Kickstart installations

This solution was created to solve the problem of enabling hands free remote installations of Linux boxes [1]. The objects that implement this solution are; a kick-start server, a networked rpm based Linux box (client), and the kick-start rpm. The kickstart server is configured as described in the resources section. Some of the code and ideals here are from Gary [2], and Aaron Gowatch.

Radio Transmission and Broadcasting

I have experience setting up radio transmitting equipment, and make shift broadcasting studios on a shoestring budget.

On the transmission side of things I can fabricate a dipole and tune it with a SWR meter, build a transmitter (if I have a kit and instructions), crimp LMR-400, and have a bunch of techniques for "masting" an antenna and gaining access to line of site.

Nagios Plugins

"Nagios is the industry standard in enterprise-class monitoring. It allows you to gain insight into your network and fix problems before customers know they even exist. It's stable, scale-able, supported, and extensible ..."

I have found that having a Nagios environment is indispensable for keeping an eye on any distributed application or set of hosts I am responsible for.
