    That may be fixable at compile time, I believe. In the worst case, you could write a patch. (Dijkstra would prefer a half-open indexing scheme anyway.)

    Coincidentally, this very book on auction theory was suggested to me by a fellow faculty member about three months ago. I guess I really ought to find some time to read it!

    It's not mixed-in, it's in a separate tank. But since the tank is an aluminum alloy (often with copper or lithium mixed in) these days, I wonder about its behavior in the presence …

    There's no Dewar vessel on the LV as far as I'm aware of. The surface of the stage is the propellant tank, made of simple Al-Li alloy, several millimeters thick. It works fine beca…

    .50 BMG is supersonic but drops in velocity rather quickly, like any other small caliber round. Depending on the position of the shooter (especially if opposite to the recording eq…

    It would make you an ignoramus in all things Latin, I assume? Given that "viri" means "(a plurality of) human males"...

    Reminded me of Part 4 of https://www.inf.ethz.ch/personal/wirth/FPGA-relatedWork/Comp... . Intellasys/GreenArrays are kind of similar but only with tiny local memory.

    It's a pervasive element, though. Which to me means two things. First, I wonder if there isn't a way of adding it ( really ) transparently into a language. Basically, whenever ther…

    In fact, it is well known that the two hardest things in programming are cache invalidation, naming things, and off-by-one errors.

    We totally can! We'll just ask the output be at least 8 out of 10. The output being...uh, the average of grades from our ten resident artists. ;)

    Perhaps something related to continuous optimization? I think Oberon experimented with that.
