KDF != PB-KDF / password hashes. There is no need that a KDF needs to be slow, e.g. you want fast handshakes for protocols (e.g. TLS), not slow handshakes.

That's not correct. THD measures some non-linearities and is unable to detect others (e.g. IMD).

Frequency and phase response are just linear characterisations, they don't model any non-linear effects. That being said, speakers and headphones all have a sound (unlike any properly designed amplifier); there is hardly any right or

Python 2 has old-style classes, new-style classes, functions, bound methods, unbound methods, slot wrappers, descriptors, method wrappers, built-ins, ... and I'm rather certain I forgot some. All kinda callable types I mentioned behave

A good formal reference uses way-over-the-top wording, a bad formal reference basically just says "ok". This is due to German law not allowing for "the employee sucks", nor allows it to use "code-speak" (it was

Data protection laws set quite tight boundaries on chatting between former and prospective employers, without the employee's consent. Further, I think the general consensus is that such chats are thought to be subject to the same rules

Germany, for example.

Yes, but differently; C/C++ explicitly prohibit zero-sized types due to object identity.

Ah, I almost got it right. It discarded too much, thus reducing throughput - even more subtle. https://github.com/torvalds/linux/commit/18aba41cbfbcd138e9f...

Linux ~4.7 or so fixed a bug in fadvise, specifically FADV_DONTNEED, that incorrectly rounded page boundaries to the effect of making some calls less effective. Found and fixed by a developer who wondered why his page cache was filling up,

That doesn't really help if the exporting application distributed the figure across multiple pages. E.g. in Visio you have to work around that by using the "export current viewport" option, which is quite annoying and irrepro

Though I agree that it was an annoying change. hex/fromhex have helped there, though a 3.4 codebase retains stupid helpers like bin_to_hex.

Python 2 is a vastly more complex language compared to Python 3. Just try to name the basic classes of types that exist in Python 2. Hint: Cannot be counted on two hands.

And/or because many Python projects have completely insufficient testing which means that any change that might break anything anywhere can go undetected.

by dom0 9y ago
Nowadays it's more likely that a Python 2 user wants to use a library and finds it doesn't work on Python 2, because the developers never targeted nor tested on 2.

So, you see, I know a bit about writing efficient code. I have held a firm belief, and still do, that if you're doing heavy lifting in CPython, you're doing it wrong, and better parallelism will not significantly help you.

Databases use journaling to avoid these issues. The difference between RDBMS' journaling and file system's journaling is the RDBMS journals application data, the file system does not (with few exceptions). Thus, a RDBMS gives you

while(1){write();} is about as far away as it gets from actual application code. This topic may be fun, but remains an utterly pointless micro-benchmark.

It's almost funny that you try to refute, or rather, dismiss, criticism of PHP with "but it's fast", when none of what you cite even mentions that. I just want to say: STFU.
