  Brigadier Martin Hotine is not quite the image of a decorated officer. His name is styled with trailing acronyms that make it no surprise that there is an official portrait, yet in that painting he appears disheveled, his tie far off center in the collar of his jacket. He leans off to one side, not quite like he is sitting for a portrait, but more like he was caught in the middle of something. Pho

  During the heyday of AT&T, it was often said that the telephone system was the largest machine ever built. The "hello machine" certainly was vast, but whether or not you consider it to be a single machine raises challenging questions of definition. The Internet, I think we can all agree, is not a single machine but a system of interconnected ones. The telephone network, though, felt a lot more lik

  Email, one of the most pervasive and enduring technologies of computer networking, was invented in about a dozen places by dozens of people in the 1960s. It's hard to lay out a clear history of the technology because it's just so obvious—pretty much as soon as more than one person could use a computer, there was some kind of mail facility. These ranged from mainframe-centric systems where all of t

  In 1914 the Department of the Interior, through the Bureau of Reclamation, investigated the possibilities of developing the Columbia River. Thousands of arid but potentially fertile acres needed only water to become the Imperial Valley of the Northwest. Locked in the mountain ranges were valuable ores awaiting electricity to turn them into needed metals. Two years later the State engineer of Orego

  Through decades of consolidation, reorganization, and divestiture, AT&T left a famously complicated corporate history. One of the greatest enterprises in American history, arguably the greatest enterprise, AT&T has often rivaled the federal government in the size of its budget and workforce. One of the reasons, as we well know today, was monopolization and its close relative vertical integration.

  It has been an unfortunate turn in the software industry, one of many as of late, that gambling is once again one of its primary engines. With the rise of almost nationwide online sports betting, not to mention prediction markets, making odds on real-world events and extracting the money of suckers is no longer limited to island nations. It is a great American pursuit, or at least, that's what mod

  The submarine is a surprisingly ancient technology—at least in its early, primitive forms. The idea is quite simple, that a well-enough-sealed boat ought to be able to submerge and resurface. It's the practicalities that make the whole thing difficult. It is generally considered that the US Civil War was the first use of submarines in combat; these were primitive machines with very limited operati

  If you've done much with modern cellphones, you've probably noticed just how odd the architecture can be around audio. Specifically, I mean call audio: modern smartphones have made call audio less of a special case (mostly by just becoming more complicated in general), but in older phones you would often find arrangements where the cellular modem 1 had direct analog audio to the microphone and spe

  Light: it's the radiation we can see. The communications potential of light is obvious, and indeed, many of the earliest forms of long-distance communication relied on it: signal fires, semaphore, heliographs. You could say that we still make extensive use of light for communications today, in the form of fiber optics. Early on, some fiber users (such as AT&T) even preferred the term "lightguide,"

  Years ago, when I was in college, I had one of those friends who never quite had it together. You know the type; I'm talking lost a debit card and took three months to get a new one because of some sort of "mixup" with the credit union that I think consisted mostly of not calling them for three months. In the mean time, our mutual friend ended up in a quandry: at WalMart, at one in the morning, wi
