No More Sprint

Finally dumped Sprint due to a failed EVO 4G LTE. Ended up going to Verizon with a Galaxy S4. Yeah, one evil over the other, but the big thing was that Sprint’s service sucked rocks in a big way. They are literally the only major provider that does not have LTE service in my area. […]

Storing IPv6 Addresses in MySQL

Last year when I was searching for ways to overcome the lack of built-in IPv6 functions in MySQL, I was curious how other people were solving the problem.

Netflix on Roku Bandwidth
