There is a just-so story that explains the existence of money. Before money, the story goes, we all had to barter for the goods we wanted. If I wanted wheat and had chickens, I needed to find someone who wanted chickens and had extra wheat. Money solves this “double coincidence” problem by letting me sell my chickens…

This is the third part (I, IIa, IIb, III) of our honestly-who-knows-how-many part series laying out some general guidelines for how pre-modern armies are recruited, raised, equipped and paid. In th…

In the United States, we are losing our fondness for cash. As in many other countries, cards and other types of electronic payments now dominate everyday commerce. To some, this is a loss. Cash represented a certain freedom from intermediation, a comforting simplicity that you just don't get from Visa. It's funny to…
The story that The Simpsons' creator Matt Groening once illustrated a brochure for Apple back in 1989 has been making the rounds of the internet for a while now. However, in addition to that brochure, Groening did other artwork for Apple around that same time period. For anyone unfamiliar, Apple hired Groening to…
The vintage IBM circuit board below has a large metal block on it that caught my attention, so I investigated it in detail. It turns out t...

As previously discussed on this blog, Intel decided to quit the desktop board business in 2013. What has not been discussed is how Intel treated the buyers of the last generation (i.e. 8-series Lynx Point chipsets) of those boards. Since I have now acquired two of those boards, DZ87KLT-75K and DQ87PG, I had an…

Tools like iTerm2 , or PuTTY , or GNOME Terminal , or the classic xterm and rxvt are all “terminal emulators”; they take raw text and formatting instructions and interpret them to display pretty text on the…
