Consider this: I don't even know what hmac is, and it's implemented in a library. Also, I can't overload return values on their own in C++, I would have to overload the whole signature. In fact, to get the same monadic result

I'm not convinced so either, just that it doesn't not make sense. As for SoA, I'm thinking of two relatively new formats and applications that have default nullable types, are SoA, and are specifically targeting memory intens
93.
by henrydark 4y ago
But now you've forced computeHmac to only work only secrets, when there is no such need. You've coupled an implementation of an abstract algorithm with the particular case that _you_ want to use it this one time with sensitive sec

How do you operator overload in C++ so that calling computeHmac(secret(string)) returns secret(string)?

Given that they mention SQL more than other things, and stress SoA and memory intensive applications, I think this makes more sense than it would otherwise
96.
by henrydark 4y ago
But it's not just operator overloading, there seems to be a monad-like "secret" that makes calls to func(a, ...) -> b with secret(a) return secret(b). The example doesn't spell this out explicitly, but I think those

I don't k ow anything about wolves or parasites, but those two things don't contradict each other. Maybe wolves with the parasite are exactly more likely to form such a family unit

Replicate looks like numpy's repeat. For example np.repeat(list("abcd"), [2,1,0,2]) is equivalent to the first example in the link.

This is circular: sure, if telnet is _obsolete_, then remove it. But being obsolete exactly means no one is using it anymore. If someone is using it, then it's not obsolete. Regarding security, some would advocate that telnet, or whate

Except that dark matter might not actually exist, and it's a change in equations that is needed. I'm not sure what the software analogy is, except that there's no software dark matter, just people not familiar with their tool

This isn't surprising given that it's well known that we share more than 90% of our DNA with tree creatures across the universe

Working with sage for about 17 years, I've had the complete opposite experience. There is no alternative for holistic number theory, group theory, and algebraic geometry (except maybe MAGMA, which I haven't used in years), and sag

This fits with the literature on block vs random order exercise in learning motor skills, where random order mostly outbeats block. For example see [1] [1] https://best-essays-service.org/essays/health/the-effect-o

I often find that downloading lots of data from s3 using `xargs aws sync`, and then xargs on some crunching pipeline, is much faster than a 100 core spark cluster

With all this work to remove allocations I get the feeling that what really is needed is C++ with Go's concurrency syntax and runtime

that's for real and complex fields, and it's not exactly that. I don't think there's anything better than O(n^2) with no conditions

I once noticed a similar state machine in a restaurant I used to patronize. Instead of taking table numbers, they would bring toothpicks when coming to ask if everything is Ok. The way I upset the system was to hide the toothpicks. The wait

To be fair, mathoverflow.net has always been for professional mathematics, mostly for professional mathematicians. Though these days even professional questions are sometimes treated poorly.

Python has coroutines (in the original sense), so one can implement almost Break-break. For example, it's easy to implement an object so that this will work as expected: from easytowritelibrary import LoopManager lm = LoopManager

Specifically the original double loop example also has this behavior and complexity. If the loops were written as for y in a2: if cond: break for x in a1: # something then they would have O(|a2|) complexity instea

This could be fine, but it does restrict things somewhat and could lead to more unexpected results. The piece doesn't present the correct way to use multiple inheritance in python, so this section is a bit of a strawman. Namely, it is

I'm sure that most python developers who have worked with pickle for more than 3 lines of code can confirm that pickle does not in fact just work
