Data Science

Posted on 2015/02/02

I’ve started work on a Data Science Certificate through John Hopkins University. There are nine courses total. The first is “The Data Scientist Toolbox.” I’ve been meaning to get more up to speed on R and R Studio, this should help.

Reading RFCs for Fun

Whenever I am having a bad day, I like to read RFC 1149 – A Standard for the Transmission of IP Datagrams on Avian Carriers which describes how “Avian carriers can provide high delay, low throughput, and low altitude service.” It contains gems like “Multiple types of service can be provided with a prioritized pecking order” and “An additional property is built-in worm detection and eradication.”
This RFC was actually implemented and tested by the Burgen Linux Group (read more here), although the ping log seen below does indeed show it is a high delay implementation. If you are technically inclined, read it here for a good laugh and the implmentation details here.

Entering the third year

Third year Begins
Eight terms down, four to go. The second year as a doctoral student is over. What a ride! After many discussions and much advice from committee members and mentors, i have finally committed to reducing the scope of my dissertation a bit. This next term will be all about getting ready for my proposal defense….and a fun elective on mobile development theory.

Soaring Fun

I haven’t been soaring for awhile now, as my glider awaits an annual and some minor maintenance. This past Saturday I took a friend flying in a Grob Twin Astir. I captured many photos and several videos in flight using my Google Glass. This one starts as I enter the pattern in preparation for landing and continues all the way to exiting the glider.
