The same is true of Swift, and Swift can also call into C whenever it likes. The difference is that Swift can do the same for Objective-C at full fidelity, including support the full Objective-C feature set (ARC, arbitrary selectors, interf

You can definitely default on a negative rate mortgage, by not paying your monthly payment. You cannot pay nothing each month. Instead, the principal reduces each month by more than the amount you paid. You still have a term over which you

`some Shape` is literally identical to `impl Shape`, including the semantics you discuss above. The compile-time return value of a function returning `some Shape` must be the same on all execution paths. It just avoids expressing to the cal

It's worth noting that the iOS and macOS keychains are very different. In fact, if you check the design docs you'll find they share only four functions between them. Essentially, as far as I could tell, the iOS keychain particip

Requests cannot throw errors from urllib because Requests does not ever invoke urllib code. Any error that does not inherit from our top-level exception is a bug: please let us know so we can fix it.

No, the OpenSSL version is the only relevant factor here.

The python.org official installers are all linked against the system OpenSSL. You need to build from source to avoid that. I recommend getting Python from macports in this case, as they should allow you to link against their provided OpenSS

The problem isn't Python, it's OpenSSL. OpenSSL got TLSv1.2 support in version 1.0.1. Any older version of OpenSSL doesn't support TLSv1.2. That affects a number of platforms: - the system Python on macOS, which link against

That's not how the Westminster system works. Parliament has the right to legislate more or less as it pleases, and is not bound by any superior authority, including the courts. The courts in the U.K. cannot strike down Acts of Parliame

Sorry, let me be clearer. The reason that just having an in-memory Reader or Writer doesn't solve the problem is that the failure modes don't match up. An in-memory reader/writer has basically no failure modes beyond ENOMEM.

Yeah, so that's very reasonable. In Python-land this is all pretty easy. For example, HTTP/2 is a protocol of the first kind ("variable-length data structures with length prefixes") at the framing layer, which is impleme

I think that's a tempting conclusion to draw, but it's not quite right. The standard interfaces of Go reduce the pain, but the design principle ("Don't do I/O in parser or state machines") remains solid. The re

It turns out TLS isn't that bad. OpenSSL exposes a "memory BIO", which is basically exactly this. You send in writes, and then emit data when you can, and in the meantime it buffers. It's a bit more limited than that, bu

We're working on a draft that will allow clients to signal what resources are already in their cache. This should allow us to reduce the bandwidth risk of unnecessary pushes.

This is a real worry, but as with all things the actual behaviour of H2 on lossy networks is more complex than that. TCP's congestion control algorithms don't work that well when you have many TCP streams competing for the same ba

Yeah, I agree that for constrained devices this is somewhat problematic, though I'd say the only big concern there is header table size. Even that can be coped with, worst-case by just enforcing the lower-limit from the get-go and GOAW

This is because nginx has some interesting assumptions about the HTTP/2 preamble works. See this mailing list thread[0] for discussion about it. See also the nginx bug[1]. The TL;DR is that nginx wants to do some weird stuff with flow

You wouldn't. What I was respond to was this specific sentiment: "With Go it doesn't matter if an operation is blocking or non blocking, that fact can totally be abstracted from the client code." My argument was that tha
