If anyone actually ever wrote that, pre-C23, then more likely than not they intended for i to be a double. Otherwise, why write 0.0 when 0 would suffice? It could go either way: Switching to C23 could cause a bug, or it could fix a bug.

The term is weakly typed . Weak vs. strong and dynamic vs. static are orthogonal.

Appealing to quantum theory to defend free will does not make sense. If the quantum randomness is fundamental, and reality is stochastic at heart, that makes it non-deterministic, but it doesn't make it any less mechanical. It's

Managers won't be surprised ... if they've read the 1981 book. I think most people would be surprised to find negative correlation between individual ability and team ability, unless they've read this book or something like i

Lawyers have a saying: "Hard cases make bad precedent." I think a version of that applies here. ("Hard cases make bad definitions"?) We have a real and observable phenomenon surrounding us, and we have a name for it, &#

We're not talking about random changes. We're talking about paying attention to the measured performance of changes made for other reasons. Just like in this article. The author measured, wondered, investigated, experimented, an

All I/O delegates to the kernel, eventually. It's pure Python in that there's no cffi, no ctypes, no Cython, no C extensions of any kind.

Of course in this case there's no FFI involved - the open function is built-in. It's as pure-Python as it can get.

The PyObject header is a target for optimisation. Performance regressions are likely to be noticed, and if a different header layout is faster, then it's entirely possible that it will be used for purely empirical reasons. Trying dif

It's me who should be sorry, I meant "let him have his day in the sun", not "have at him". Only now did I realise that it could be misunderstood.

The problem is that now you need to define what "pure logic" is. Here's my definition: Math is the study of intersubjective knowledge.

We have different mental models. Your mental model, if you will forgive the straw man, is that SELECT over multiple tables is conceptually equivalent to nested for-loops over each table, and the WHERE condition is an if-statement. My mental

If it was that clear, then I wouldn't have asked.

I don't. I put distinct on everything by default, because it makes SQL more like relational algebra. What's the argument for avoiding distinct? Is it performance? I've often wondered if the (sometimes redundant) distincts

I stand corrected. You rarely spell out these larger numbers, so the exact spelling can be hard to remember. On similar lines, seeing "tredivte" on the list gave me a start - it somehow doesn't look right, even though it is.
