If the advertisers can see the MAID for each ad impression, then there's no need to be too specific about who you target - it'll just cost you more. On the other hand, if the advertiser doesn't get to see the MAID-per-impression, then the easy solution is to supply your one target MAID, plus another 999 bogus MAIDs (or, if the platform verifies that MAIDs are accurate before allowing you to use them, then you use 999 MAIDs from Liberia or some other country that your target won't visit).
This question of "what skills are students missing?" reminds me of the new teaching methods they were trying out as I started high school. The new teaching program centered around objectives. The idea was that each objective was a skill that the student needed to learn, but the upshot was that you had to score more than 70% on every single quiz to pass the class, and that you could retake every quiz you failed, repeatedly.
The implementation varied between classes - in my World History class, there were a large number of objectives, and each objective was met by a small quiz that tested ~one skill. (There were a lot of retaken quizzes in that class.) In Biology, there were about 10 objectives for the entire semester, so you could still pass while missing a few small skills, as long as those missing skills were spread out among different units.
My high school used that "objectives" system less and less as I moved up the grades -I assume that most teachers got tired of it pretty quickly and just decided to make their usual teaching material "look like objectives" rather than rebuild their curriculum in later years.
The Microsoft campus in Redmond would most likely not be knocked over by the tsunami: a rather hilly Seattle is in the way, then there's the large Lake Washington, and then Redmond is another ~40 feet above the lake on the far side, plus another ~2 miles inland. A fair amount of the energy of the tsunami is going to be expended by the time the Microsoft campus gets salted. (Kirkland is west of Redmond, adjacent to Lake Washington, so it's a similar-but-somewhat-less-optimistic story there. Fremont is adjacent to Seattle and slightly inland, so it will be worse there.)
Of course, the infrastructure of the greater Seattle area is going to be trashed, but chances are good that the Redmond and Kirkland campuses of Microsoft and Google respectively would be intact.

This isn't even "the big one" as the OP describes, much less "the really big one", but it's a rough description of where the flooding will happen. Downtown Seattle (up and left of the word SEATTLE on the map, with streets in a dense diagonal grid) won't be strongly affected, because downtown Seattle is a hill. With an 8.5 or 9.0 earthquake, of course, Seattle will be much worse off, but there's still some hope that Redmond and Kirkland won't get too damaged.
Star Control II uses a starmap as copy protection ("tell me the constellation at these coordinates..."). I lost the starmap at one point, but if you can remember just one of the answers, you can just keep running the game until that answer is the correct one. (The copy protection is at the very beginning, and the game won't bug you during play.)
Using a socket wrench rather than, say, a crescent wrench means there's more nut in contact with the wrench at any given moment. So the wrench doesn't have to be quite as strong, since the torque is distributed over a larger surface area and thus a larger volume of wrench is available to absorb it.
The current knowledge of jellyfish intelligence is "we've figured out they have memories." Jellyfish are extremely simple creatures; the "brighter" ones are known for their ability to avoid obstacles. [1] These are not particularly sentient creatures.

You convince your loved ones to switch to something else. If they won't, then you must realize that, deep in your heart, you love freedom more than you love your loved ones, and must switch to non-video calls or other methods of communication.
The market is large enough, the transactions are relatively large, too.
In Kenya, M-Pesa is by far, the #1 payments service, with nearly half the country using it. It grew acceptance as a replacement for the other way of remitting money from the cities to villages - busses. Prior to M-Pesa, bus drivers would act, for a fee, as money carriers, bringing income back from the cities to families back home.
The competent hackers were, literally, brute-forcing the old system. Bus drivers are easier to compromise than mobile handsets and infrastructure.
Almost every single non-reply post on this article is criticizing how much the app isn't AirBnB. Maybe the new measure of success on HN is finding the excellent discussions under those criticizing posts? Those criticizing top posts always have a huge amount of discussion under them.
