Sam Kear (skear)

Joined 4 years ago from Kansas City. Last activity 2 weeks ago.

I'm a technology enthustiast that enjoys sharing my knowlege about a wide variety of computer related topics.

I have a bachelors degree in Information Technology from the University of Missouri-Kansas City.

Currently I work as a network analyst for an algorithmic trading firm in the Midwest.  My primary focus is optimizing networks and servers for extreme low latency operation.  As a registered representative for a broker-dealer I hold both the FINRA Series 7 and Series 63 licenses.

Previously I worked as a field technician providing onsite computer and network support for hundreds of clients in the Kansas City area.

I enjoy working with Linux and have an interest in embedded devices.  I'm also a big fan, and supporter of the pfSense project which is based on FreeBSD.
