Precise geolocation via Wi-Fi Positioning System

Trilaterate (or multilaterate). Angulation uses angle, like a directional antenna, constructive/destructive interference for beamforming (this is how airplane landing systems work if I'm understanding it correctly), or optics like our two eyes, to find the angles to a target from known positions in order to determine its position in space

Trilateration is based on distances from known locations, determined either by signal delay (GNSS does that; newer cell towers also but call it "timing advance") or signal strength (used with both WiFis and cell towers)

> locally, given the WiFi hotspots

You'll also need a local database with the hotspots' positions (usually those aren't actually measured but estimated from observations at different locations). I'm not aware of a device that ships with this, nor popular software that uses it as its primary method, as such databases are many gigabytes. Thus this is typically not local; you're sharing your data (thus location) with the server which then kindly tells you where it thinks you are

GPS receivers sold to public also required to not operate at certain altitude/speed to prevent it from being used in ballistic (and probably other kinds?) missiles.

A couple weeks ago there was an exam in an R1 institution that double booked the facility so one section did the exam in person on campus and the other did it "from home". The score distribution of the in person exam was a typical bell curve, and the distribution of the online exam looking like a power-law curve with over half the students scoring 100%.

Thankfully this outraged the professor, and through a variety of means (which I will not disclose publicly) over 25% of the students were caught red handed. Actions are being taken against them, though I'm not sure how far they will go. The evidence against them is overwhelmingly conclusive. In some cases the evidence led to more evidence of cheating in other courses. It seems clear that more that 25% cheated, but I guess catching some is better than none.

As someone who is keenly aware of this crisis, I feel tiny bursts of relief when I see these small wins, though it does feel a bit like bailing an ocean with a teacup.

    geo.provider.use_corelocation: true/false # presumably for tracking on MacOS

    geo.provider.use_geoclue: true/false # presumably for tracking Linux users with Geoclue2 provider [1]

    geo.enabled: true/false # presumably, turns the whole thing off

It also appears[3][4], that setting geo.provider.testing to true might be required.
