Could we get Internet choice in San Diego?
Today Google announced that they are exploring bringing Fiber to San Diego. This is excellent news, but it will be a long time before anything actually happens. With Time Warner Cable bringing 300 Mbps/20Mbps connections to us later this year and possibly having gigabit from Google, consumers may actually have a choice in San Diego.

Wireless Link Becoming Limiting Factor
I've been experimenting with WiFi access points in the past few weeks and have tested the performance of the wireless link. The max speed of 802.11 n (most of my devices are n devices with a few ac and even a g device or two) is 300 Mbps or 450 Mbps depending on the number of antennas. That may sound fast, but actual performance is a lot less than that and in my testing, I was able to get about 225 Mbps using Iperf. Usually I can get between 50 and 150 Mbps. That should be plenty fast enough to max out many Internet connections; I currently pay for 50 Mbps down/5 Mbps up.

Determination or insanity?
For the last week I've been tracking down a bug in my current project. I've spent just about every spare minute including the weekend trying to figure out why my code works in a test app, but not the main app. I rewrote a huge piece of some communications code to no avail. I tried threading the communications, putting in proper locks, changed how I processed the bytes, etc. Basically when I was receiving large amounts of data from a Bluetooth device, some data was lost in the transmission and the checksum was incorrect; for small amounts of data, this problem didn't show up. At this moment in time, I believe I'm the only person in the world working with this combination of hardware and software which made using Stackoverflow useless.

Troubleshooting OS X Server's Websites
Today I was trying to install a program on my OS X Server and the software complained that something was listening on port 8080. I couldn't figure it out, so after a bit of searching I found a command that could get me closer:
