Okay, so you travel from, say, Washington DC to NYC and then you have to set your clock back by... I think it's like 13 minutes? Which is why railroads started instituting time zones in the late 19th century: because it turns out havin

Almost all of the new highway construction is for passenger cars. Yes, the interstate highways were built in part to facilitate intercity truck traffic, but the reason for building yet another beltway around, say, Houston isn't for tru

I've been traveling around in Europe without a car for several days now, including several fairly rural areas. There's a distinctly American trope in play, that if the bus or train doesn't stop more or less exactly at your de

Well, even as-is, it turns out that the kind of assembly language that Knuth originally wrote it in itself had a very short lifespan. MIX assumes a single accumulator register for arithmetic, which hasn't been a common processor archit

People tend to rely on air temperatures when in reality the lethality of heat is probably more linked to the wet-bulb temperature. The human body has a natural resting temperature of about 37°C, and metabolism of course generates more heat

The author is comparing a 1990 hypothetical compiler to a 1970-ish compiler. The late 1960s and early 1970s are essentially when all of the foundational parser theory gets laid down. By the late 1970s, we're getting into autoparalleliz
