My interests revolve around designing and building systems, particularly communications systems (hardware, software, protocols) and VLSI/ASICs/FPGAs.

In a former life I was an FPGA and embedded systems engineer, working on bringing up custom PCBs from initial board testing (voltages, PCB traces) to application level software development. I now work on large-scale communications systems.

Lately I've been tinkering in Linux and UNIX kernel development, low-level TCP/IP, Erlang/OTP, C++11, and wireless mesh networks (e.g. ZigBee). And I always have an itch to start writing some Verilog/VHDL.

At the end of the day I just enjoy making things.

It is what I ended up doing. My SysAdmin told me to do it too! :) I think he just didn't want to deal with me.
comment Override RPM install path
Thanks! I have and will continue to complain to the admins. They think 10G for the root partition is plenty...never mind how often I have to clean up all of the corporate logging crap in /var....

I was able to run 'modprobe -r pcspkr', but when I played the test sound in Gnome's "Sound Preferences", I could still hear the sound. When I tried 'modprobe -r snd_pcsp', I got a "FATA: Module snd_pcsp not found" message.

Turns out the little devil was PackageKit!
