To be slightly fair to the parent comment, it seems at least a bit valid to choose whether to consider the social security tax to be revenue to the government and social security payments an expense or to treat them as an entirely separate

The same problem that a hybrid architecture solves for ships: the ability to use physically small electric motors with very high power density that are mechanically decoupled from the rest of the vehicle. This lets a bunch of designs pull o

I would guess that a military version would be a hybrid: electric motors as in all the e-VTOL prototypes, enough battery power to comfortably take off, land and maneuver in combat conditions, and a small hydrocarbon-fueled engine to recha

How many CAFE compliant “light trucks” do you see around? CAFE is a great example of a well-meaning regulation failing because the people who developed and approved it didn’t think through the obvious consequences.

An idea I’ve been kicking around (which isn’t quite applicable to this use case, I think) is to aggressively restrict the Sec-Fetch- headers on user content. If a server is willing to serve up an untrustworthy SVG, it could refuse to serve

If it’s calling clock_gettime, it should be fine. If it uses RDTSCP, it should be fine (assuming your system actually has synchronized TSCs, and there is a long history of this failing). If it uses the sadly vendor-dependent magic incantat

The UniFi U7 Lite is $99 and appears to be every bit as good as the more expensive gear unless you want 6GHz or need extra radios or have clients with more than two spatial streams.

Traditionally they were done in FORTRAN or C or maybe bespoke DSP code, usually using ordinary boring complex numbers. Sometimes you’ll see FFTs over rings, called “number theoretic transforms”, used to multiply very large integers. I supp

I can also implement compliant IEEE 754 floating point arithmetic, with all rounding modes and exceptions, in Conway’s Game of Life, and I can implement that on a Turing machine and emulate that Turing machine in Brainfuck. This does not

I can guess: Pure lambda calculus doesn’t have numbers, and FFT, as traditionally specified, needs real numbers or a decent approximation of them. There are also Fourier transforms over a ring. So the task needs to specify what kind of n
