Right. The big problem with accurately bisecting a 180 degree angle is you need to have access to points rather far in both directions from both points. If you want an accurate right-angle corner near the edge of a property that's fl

QUIC has its own flow control. It's not raw UDP. Now, I wish ToS/QoS were more broadly usable for traffic prioritization. It sounds like you're using UDP vs. TCP as a proxy for ToS/QoS. At a minimum, you're still

Some early Lisps had both compiled and interpreted mode, where the interpreter used dynamic scoping and the compiler used lexical scoping. (Which, I presume, caused much developer confusion when code worked fine in the interpreter and got

Note that weak typing and dynamic typing are orthogonal. I believe you're expressing sympathy for strong dynamic typing: types are checked an enforced dynamically by the runtime (such as Python raising an exception if you try to add a

Too late to edit, but it was Rolls Royce trying to stage Wankel rotors for a Diesel engine, not Mercedes. The Mercedes (Daimler-Benz) attempt was a modified rotor shape to increase compression. https://en.wikipedia.org/wiki

At my last job, I occasionally ran into people worrying about SHA-256 collisions for non-maliciously created build artifacts, so I wrote an internal wiki entry with the back-of-the-envelope estimates. If you're really paranoid, use get

Over what time frame do you believe global warming has a non-negligible chance of causing human extinction, as opposed to crashing populations, dramatically reducing quality of life, and/or destroying our current civilization?

This has been done in order to make a Diesel Wankel (a Mercedes prototype engine, IIRC), since there's a fundamental upper limit on the compression ratio of a Wankel rotor, which isn't high enough for a reasonably running Diesel.

The properties of the permutation are dependent upon the encryption key, so a client being able to select malicious inputs to get long cycles implies either that the client knows the AES key, or that the client has broken AES. In any case,

Cycle-walking FPE has a (nearly) unbounded upper-bound on latency. Breaking the 122 bits into two 61-bit halves and using AES as the round function for a Feistel cipher gives you a constant 3-encryption latency instead of the expected 64-en

You got me. What's that format / magic number? At first I thought it was the zlib header for incompressible data, but that's not right. Is that just the MAC address of some NIC you own?

Alan Kay is generally credited with coming up with the term "object-oriented", so for better or for worse, many people defer to his definition and his embodiment of ideas when looking for a strict definition of the term.

What does "pure binary" even mean, though? I think you mean a bare-bones COM-like format where the binary gets loaded at an ABI-determined static address in memory, the instruction pointer is set to the first byte of the binary,
