Yup. We don't even have "cruise control" that is usable in the wintertime -- but we just placidly believe every yahoo who claims to have solved the problem of completely autonomous driving! Have we ever heard of Unit Testing?

Geohash is great, but doesn't include any error detection or correction. This means that one (undetectable) symbol changes, and you could be half-way around the world from the original Geohash location. The EZCOD encoding provides acc

The EZCOD uses a base-32 encoding that equates 0, O, o, and , 1, I, i, and 2, Z, z, and 5, S, s. The real key asset that EZCOD has vs. the other common encoding systems is the ability to correct errors -- not just detect them. Even the mos

The incentive to publish negative results is: "to not be labelled a charlatan". The widespread non-publication of negative studies (and, tragically, their datasets) has, rightly, tarnished the validity of all published scientific

Actually, it would appear that scientists did, in fact, kick everyone in the balls for 20 years: http://www.americanscientist.org/issues/feature/2014/6/the-s... Perhaps it was accidental in most cases.

Indeed; since timezones have the same abbreviations for multiple different timezones, it is difficult to collect a set of abbreviations that are consistent across a data set. I wrote cpppo ( https://github.com/pjkundert/

Simplicity and reliability. The rotor is completely inert (no windings). The big drawback has historically been "torque ripple". However, with modern high-speed power electronics, the current to the windings can be modulated to counteract

This is the argument that comes up every time a C vs. C++ discussion occurs. It is faulty, because it assumes a false premise -- that the C and C++ implementations will be largely of the same complexity. Unfortunately, in the C implementat

Because redefining tab width as something other than 8 is, quite frankly, a disaster. The problem is, a "tab" does not advance by 8 spaces; it advances to the next column divisible by 8! Shockingly, most editor writers don't seem to realiz
