Actually, the article (correctly) expanded the acronym as cost-per-mille (note the 2 L's). Mille is latin for thousand.

I think he said that make solved only a small, relatively easy part of the problem, and he didn't want to have to work around the limitations of make and the syntax of makefiles. He also mentions that different make implementations hav

Maybe it compares output file timestamps against input file timestamps to decide whether to re-build, as make does? It's hard to figure out details like this without either documentation or source.

Feynman was perversely proud of the fact that when tested (as a child?), he _didn't_ have a "genius" IQ. Wikipedia claims it was 125, but I thought I'd heard him claim it was 134, one point too low to qualify for Mensa.

Heh, looking at my neighborhood, the smallest available file is a scan of the 1933 7.5-minute Sierra Madre quad, 5.24MB, and the largest is the 1979 30x60 minute Los Angeles quad, 44.53MB. Most of the 7.5 minute quads seem to be in the 15-3

Drawing a rough box on a map of the US I estimated about 40 degrees of longitude by 20 degrees of latitude. The most detailed maps are the 7.5-minute quadrangles, which I believe are available for nearly all of the continental US. Since 7.5

I remember reading about "vendor" branches in the cvs documentation (probably in the early 2000s), which if I recall correctly were trying to solve a similar problem to sub-modules in git. So I don't think the Rubyists invent

I had the impression (from talking to traffic engineers) that it was pretty much common knowledge in the field that newly constructed highways only alleviate congestion for a very short time (a year or two), after which it returns to previo

This sounds interesting, but before anyone starts changing their lifestyle based on this, you should be aware that not only isn't this a double-blind trial, there's no control group, and the results lump together subjective and ob

I would expect spammers to choose names at random from a list of common first and last names. Though I sometimes see spam emails with "$FROM" in the From: field!

How could someone's real name always fall "within some expected value"? Someone who's real name is an outlier is going to be an outlier, they're not going to "fall within some expected value." If they&#x27

They don't know, they guess, based on some heuristic algorithm. In Google's case, their algorithm informed my son that the name on his birth certificate is not a "real name", and forced him to pick another one (he kept h

I don't know about whether they were joking or serious, but I think their point was that for any person, there are probably some charities they'd object to funding. I know people who won't donate to Habitat for Humanity (US c

You're comparing a fairly stable, relatively well understood danger with a rapidly growing, less well understood danger. Elsewhere in this discussion, someone quotes a CDC estimate that by the end of the year the number of ebola cases

But the assholes insist that they're _required_ to be that way, by the rules of capitalism, and almost no one seems to argue with them (except those "spouting left'ish wing propaganda").

Keep in mind that hospital "costs" are largely fictional. When the bill says $45 for a sponge, the insurance company has negotiated a much lower rate for the whole procedure, and if you go to the hospital and say "I'm a
