You are aware that not all research leads to concrete, patentable ideas, right?

Thanks. And wow, the CPython source code seems to be very much readable. I've been meaning to dive further into Python internals for a while, maybe this is the time to do so.

Okay, I think I get it now. The check you refer to is done inside the BINARY_ADD implementation. That's why the bytecode is the same for both cases. Am I right?

How can the interpreter know, at bytecode compilation time, that x is bound to an int? Surely it generates two code paths, one for the "common case" and another for when x is a general object with an __add__ method?

Technically, you could prove P=NP without actually discovering a polynomial-time algorithm for an NP-hard problem. Not all proofs are constructive.

This reminds me of this (slightly old) article, wherein the authors observe that about 1 in every 30,000 TCP packets fails the TCP checksum, even though the actual errors should have been caught by the link-level CRC. They go on to speculat

Note that no error detection code is able to detect all errors; it just lowers the probability of an error passing undetected even further. (CRCs are pretty robust in that they always detect sequences of errors with length <= N, with N

Interestingly, any physical, finite machine can be modelled as a finite state automaton (which is even more limited than a pushdown automaton) with a large enough state space. The distinction only comes up when you consider idealized infini

How is a "limit to how much memory [one] can address" not a physical, rather than logical, constraint? Really, the crux of the matter is that you can have a function call itself an unbounded number of times in C (i.e. unbounded recursion).

They hint that they use this huge regex instead of a parser for performance reasons. At any rate, the regex was not written by hand; it is a concatenation of simpler, easier to understand regexes.

The key observation is that, since counting votes is an inherently distributed problem (with a comparatively simple centralized step at the end), you can always deal with it by adjusting the number of polling stations. I can speak for what

In general, function calls cannot be inlined by the Python compiler because (almost) any function name may be re-bound to a different object at run time. A very smart compiler could probably attempt to prove that no such modification can oc

At the very least, (s)he would have had to understand the main ideas to deem them interesting (though perhaps the details were difficult to follow). So yes, you're right that it isn't technically a contradiction. The way it was written did

On the topic of self-contradicting reviews, I once got one where the reviewer began by noting that "the paper is very difficult to read and almost impossible to understand" and proceeded to remark that "it contains very interesting ideas"..
