    How accurate is this two-pass approach in general? From my outsider's perspective, it always looked like most of the difficulty in implementing Lanczos was reorthogonalization, whi…

    "Esports" is not a league. That would be like saying "sports" is a league. There are leagues around some games (like the ones mentioned in the article). There are also events with …

    It's new because it makes no sense. There already is an implicit "branch" on every array access in C, it's called an access violation. Do they test for a segfault on every single a…

    The only series that release "every 12-18 months" are sports games and Call of Duty, and I can assure you that the overlap between that audience and the Persona one (which has five…

    Nice writeup and algorithm. My first instinct would have been to take the lazy way out and just use a table with 365 entries (or 366, or both depending on the implementation), but …

    First of all, you are correct that nonlinear optics usually requires high field strengths. But... >Photons are bosons and therefore are very reluctant to interact, essentially requ…

    For completeness, there are languages that do not require stacks to implement (nor any workarounds that in practice emulate a stack). If you do not support explicit recursion, you …

    The usual technique is to keep a 4-element array of sums (so sum[j] is the sum of all terms of the form a[4*i + j] * b[4*i + j]), and then take the total at the very end. This allo…

    That is true. Still, we are kind of trading one unintuitive postulate (an invariant speed) for a different one: Why would we ever think that the time interval between two events ca…

    The mathematics are sound, but the reasoning around is unclear to me. The derivation shows that Lorentz transformations and Galilean transformations are the only ones that allow fo…

    MATLAB had its first commercial releases in the mid-80s and had indexing syntax that looks pretty much the same. Since it got popular very quickly, I assume that it is the most imm…

    After thinking about the problem a bit, I've come up with a completely different approach. I'm sure this is known, but I can't find anything so I'd appreciate if someone can point …

    This does look quite nice. I always felt that the operator precedence / association rules in other stack languages were by far the most difficult thing to get used to, not the nons…

    Hello and thank you for the neat article. I have not finished it yet (I'm still partway through the ML bit), so ignore me if this is explained somewhere, but as far as I can see yo…
