The US has a bunch of highly paid medics who fly every week or in some cases every day because they work somewhere with enough population to justify their practice but they choose to live somewhere hundreds of miles away, and at their incom

There is exactly one actual ocean liner left, QM2 which goes between my home city and New York. Most of the ships you're thinking of are Cruise liners, which are not in fact (unlike an airliner or ocean liner) designed to prioritize tr

That is specifically because the Tories privatised water. Historically, like most places, the vital-to-life water supply and corresponding sewage processing were owned by the public in England and Wales. People hated the idea of this be

Really often the alternative was not to make the journey. Whether that's the in-person visit to a customer site which could have been a video call (or an email) or the trip to go see how your Porsche was made in the factory. WG21 (the

This is, at best, misleading. It is common that a junction running at capacity with a pedestrian phase will always run that phase with the same timing regardless of buttons, but that same junction (never mind other junctions) may often n

Steve wasn't talking about unsafe. He was talking about being able to mint your own non-enum types with user defined niches. Rust provides for example NonZeroU8 which is an 8-bit unsigned integer that's never zero, leaving it with

Since this thread is mostly people complaining about Windows, here are two more fun anecdotes 1. I installed a new Windows-only gaming setup. Out of the box it was able to figure out how IPv6 networking works here but didn't get IPv4.

But that's just not ZSTs. All C++ is doing is, as with EBC you can overlap a thing which doesn't need any representation with any number of other such things and with the no_unique_address attribute C++ will say their total size i

That is what they claim but I'm very sceptical - not that they can preserve order but that they get similar performance.

The C optimizer is not allowed to re-order, so, unless you've specifically used some implementation override you know exactly how C will lay out basic types. Likewise packing isn't allowed by the standard, so you'd again only

The layout rules for C struct are definitely a blessing for teaching I can see that.

Python's hash table type, dict, promises that it remembers insertion order. If you put the mapping 5 => "dog" in first, then when we ask what is in the dict we'd get told 5 => "dog" first, duh. Historical

In general our types won't be comparable, suppose we've got three zero size types Truth, Beauty and Strange and we make six variables a and b have type Truth, c and d are Beauty, e and f are Strange: Out of the box a == b will not

One problem in trying to teach a "conversion" type approach is that if you didn't really understand a thing in language A where it was maybe not too important, what do we tell you in language B where it's identical (or e

The C++ design is optimised for the case where you're mostly storing Things everywhere and then at runtime code works out whether each particular Thing is a Customer, or a Product, or a Target, or an Artist, or what... I don't thi

I believe that an ML should be the First Language for Computer Scientists. It's much less clear which language we should teach people for whom it will likely be their Only Language, today Python is common, and for fields which care abo

Go is much older than Swiss Tables. Since the hash table is a widely used container type and Go aspires to having a sort of "kitchen sink" stdlib I assume Go 1.0 had a hash table, and it can't be a Swiss Table because those w

This has a section on Object Safety, I checked and the article was written this week, but "Object Safety" is a confusing name for this idea, and so for a little while now Rust calls this idea "dyn compatibility" because

This is why C++ doesn't have ZSTs, it wants all objects to have identities, the obvious way to distinguish them is by where they are in memory, but ZSTs don't have distinct addresses in memory.

But almost invariably in this context they mean "the continent" ie France, Spain, Italy and so on, probably not Scandi and not Ireland. So that's more like how people would say they're going "to the UK" when ac

There's a situation like with Amdahl's law here, which I'm guessing you're familiar with since this is HN but if not then I'm sure you can read about it. Consumer prices - the thing you're experiencing - have m
