Personally, as a website visitor and occasional author, I don’t want the performance to be good enough to ‘do the job’. I want it to be as fast as possible. I want it to be instant. For that we need unbloated websites and better protoc

Also, the software they were using (OpenDNSSEC) had an automated delay to avoid exactly this issue, but the delay period was based on a setting in its config file that was supposed to reflect the TTL of the DS record, and they forgot to cha

Page 50 of the report says that some (unnamed) resolvers do this, and “we think this [..] is a very good implementation feature to reduce the impact of mistakes”, but that it’s “definitely not universally implemented”.

Yes, it would include that kind of thing. It’s written broadly to include all fees except (1) taxes and government-mandated fees, and (2) shipping fees (which have to match the actual cost the seller pays for shipping).

> Undefined behavior[2] Given that this particular undefined behavior usually causes crashes in practice, I expect the author is talking about casting away the const but not actually writing to the pointer. Which is legal.

But if you don't use packed attributes, then the compiler will still add padding as necessary to avoid misalignment, while not wasting space when that's not necessary.

> #define sizeof(x) (size)sizeof(x) I'm guessing this is lacking an outer pair of parentheses (i.e. it's not `((size)sizeof(x))`) on the grounds that they're unnecessary. In terms of operator precedence, casting binds

Technically, using volatile between threads is a data race and therefore UB [1]; the guarantees made around sig_atomic_t only apply between a thread and a signal handler on the same thread. Though, I'd argue that the no-optimization gu

> Atomics and volatile solve different problems, though. Yep, that's why atomics are only an alternative to uses of volatile _for atomicity_. For the original use case of accessing hardware registers, volatile is still the correct

(2010) The post is still accurate, but in 2011 C and C++ added atomics, which are a more portable alternative to uses of volatile for atomicity. They can be more efficient in some cases than the locks suggested by the post, especially in C

For Wait-Or-Die, do you really need to fetch_and_add to get a transaction ID? Do you need a transaction ID at all? It sounds like the goal is just to have an arbitrary-but-consistent ordering of active transactions so that different trans
