Serial Port on the Pogoplug v2

I have run the hotel/apartment room server off a BeagleBoard-XM for a few months now. I had no case for it, so I was a little worried to have an exposed computing platform hanging out there while the cleaning team and visitors were around. This put me on a search for a ARM-based platform that was small, silent, and could run Arch Linux. Up till this point I had used the Beagleboard with Ubuntu due to the ease of install. Yes it is capable of running Arch, but it isn’t a seamless process. Additionally, being ARM v7 it was not able to run Plex which is my media streaming platform of choice for the ouya ...

2013 Investment Recap

I like to look back at the year and see how good (or bad) my investments were in stocks for the year. As the rest of the year is going to be crazy busy I wanted to type this while I couldn’t sleep last night. I doubt there will be any huge swings from now till 31 Dec. I buy and hold-on to stocks vs. quick trades so my goal is not to make a quick buck on a flip. There were a few interesting surprises and fails this year. I am leaving my overall investment dollars out so you just get percentage gained. Overall my portfolio is up 21% which isn’t my best showing, but better than zero. If anything this reaffirms that I should stick to ETF and Mutual Funds for 2014 :) ...

BASH Profile Calculator and Extractor

Most likely my favourite addition to my otherwise untouched BASH profile is the calc function. From the shell on my Linux box I can simply type “calc 2*10+10/1” and be presented with a result. Having been on a Mac with spotlight the past 3 years, this is something I truly missed. Additionally I missed a universal extractor that was easily accessible. File-roller works sufficiently in the GUI, but I wanted something quick from the CLI. Now I can type “extract archive.tar.bz2” and away it goes… ...

The Great Illusion

I started my day with a run and was lost in the writings of Norman Angell. A month or so ago I read his book, Great Illusion, and was awe-struck on how much pre-WWI Europe mirrors our own world today. He makes the case that globalization in those times would prohibit the tinderbox from catching fire due to the inter-dependencies. I see those same arguments today (article from The Telegraph) and feel a sense of misery from past mistakes being forgotten. ...

Simulating WAN Links with Linux and TC

Simulating WAN links used to be a difficult process. I would load FreeBSD with a dummynet driver and play with the settings to tweak where I needed it for the activity. OpenBSD with ALTQ made this a step simpler with the ease of bridging adapters. On a recent project for Spec Ops Technology, I needed to simulate a WAN with latency, loss, and randomness. I decided I needed to dig more into the netem work included in most recent linux distributions. Netem has matured to the point of being a very potent utility for setting up quick testbeds. Additionally with most any modern Linux distro you are online in minutes. I will post a very quick script to get you online: ...
