For example, considering a sequence like [5, 4, 7, 8, 2]

What is the 4th element? 8, but if I asked what is the "0th element", you would answer 5, but that is the 1st element. The document introduces the terminology of the zerid element (0id element), oneid element (1id), etc. to handle 0-based indexing.

If it was just because it was cheap, we'd also see similar fraud from Mexican or Vietnamese sellers, but I don't really see that.

It's great to say your software is higher quality, but the question I have is whether or not is is higher quality with the same or similar features, and second, whether the better quality is known to the customers.

It's the same way that I will pay hundreds of dollars for Jetbrains tools each year even though ostensibly VS Code has most of the same features, but the quality of the implementation greatly differs.

If a new company made their IDE better than jetbrains though, it'd be hard to get me to fork over money. Free trials and so on can help spread awareness.

The issue is the lack of synchronization between cancellation and not handling cancel failure.

All cancellations can fail because there is always a race when calling cancel() where the operation completes.

You have two options, synchronous cancel (block until we know if cancel succeded) or async cancel (callback or other notification).

This code simply handles the race incorrectly, no need to think too hard about this.

It may be that some io_uring operations cannot be cancelled, that is a linux limitation. I've also seen there is no async way to close sockets, which is another issue.

This means is damages your neurons in any amount.

Contrast to say, copper, which doesn't start causing damage until levels exceed a certain tolerable threshold.

While lead is toxic at any amount, low amounts of lead cause low amounts of damage. It doesn't change the fact that the ideal exposure is 0 and over 99% of people have about 5 to 10 times the bond lead levels found in remains of our ancestors, and that even relatively low lead exposure levels from breathing lead in the air from just air pollution are linked to dramatically reduced IQ.

Take the whole "saturated fat is unhealthy" thing.

Here's what happened:

Study finds that unsaturated fat is healthier than saturated fat, but all fat is associated with lower mortality vs carbs.

Repeated as "unsaturated fat is healther than saturated fat".

Repeated as "saturated fat is unhealthy".

This conclusion isn't supported by any research compared to carbs(!).

Same-calorie diet of high fat is healthier than one based on carbs. But we are often taught otherwise.

The saturated fat is bad (wrong) consensus is reached like a game of telephone.
