With C++17's compile-time conditionals, plus good old C preprocessor macros, you could do this: #define MATCH_VARIANT(x) [](auto& x) #define CASE_VARIANT(x, T) constexpr (std::is_same_v<std::decay_t<decltype(x)>,

As the paper's abstract states, "Quadratic cost uniquely makes the marginal cost proportional to votes purchased". The full paper shows their proof and the assumptions behind it, such as "an individuals’ value for votes

If merely 100 less-wealthy voters out of the whole population couldn't coordinate to buy a few extra votes—and they wouldn't even have to explicitly communicate, it would just take 100 people who individually hear about the issue

Sounds like the system would be doing its job in that case.

That translates fairly well into Python, with its set type and list/set/dict comprehensions. def setrange(first, next, last): return set(range(first, last+1, next-first)) fizz = setrange(3, 6, 100) buzz

"Chat stories" with "comic-book inspired" young-adult plots, made to be read on mobile phones... Sounds like they've reinvented Japanese cell phone novels[1]. Sci-fi/fantasy YA plots are also common to light no

"Unambiguous" is not the same as "trivial". C code generally reads left to right, so a trivial syntax for declaring, say, an array of const pointers to functions that take a const pointer to a char and return a const poi

I'm all for some kind of social support system to help people through automation. Unemployment benefits, basic income, subsidized retraining, those have their merits. But how does giving someone a do-nothing job, where everyone (includ

You can even solve cubic equations with origami[1], which is what allows you to double a cube and trisect an angle by adding folding to the usual tools of compass and straightedge. (It's still not enough to square the circle.) [1]: ht
