I assume it's only fast for large databases when running on a filesystem that supports copy-on-write? In particular, I assume it won't benefit from CoW on a tmpfs?

The pgtestdb readme claims 20ms setup, while OP claims 100ms. Where does that difference come from? A different postgres setup (in memory vs disk)?

I feel the template approach has a kind of awkward performance level. As the article points out, 100ms of overhead is still a lot if you incur it for each test. But once you re-use the database, it doesn't matter much if creating it ta

There is the ePrivacy directive as well, which mentions cookies (as a representative example), and I think it requires user consent in cases where GDPR doesn't.

Two of six screenshots show the app. So the rejection fits the rules and is easy to understand. I often agree with complaints that Apple's rejections are unclear or problematic, but this isn't one of those cases. And I'm kind

I think introducing unpredictable new prohibitions is a much bigger problem than the specific bans on cryptocurrency or AI written code. Especially when it leads to existing code becoming unavailable and doesn't just ban new contributi

I definitely got more out of paying full attention to lectures in university compared to wasting effort on hand writing notes. And properly typeset lecture notes written by somebody else are much better for studying than the illegible handw

Abusing IP ranges which were assigned to an organization but aren't actually used on the public Internet as private addresses is pretty common. Sure, it's bad practice, but not a big deal.

When designing a character on a computer, you play around with many options, until you settle on one of them. Since you did exactly the same thing for all those variants, it's difficult to remember which one you ultimately picked. Writ

I consider an inline-pointer a form of inline-metadata. When I mentioned that inline metadata isn't necessary I was referring to the kind of external lookup you describe.

Yes, large allocations need to be aligned to `alignof(max_align_t)`. But small allocations could have a smaller alignment. For example a single byte allocation can actually be a single byte with no alignment, since types can't have an

Your bump allocator suffers from integer overflows turned into buffer overflows when the requested allocation is big enough: if (a->cursor + size > a->limit) return NULL; // out of memory I'd rewrite it like t

by CodesInChaos 3mo ago
There is no reason an allocation needs to contain any inline metadata. And even if it does, the allocator could choose to make it unalined, and pay the cost of an unalined access on de-allocation.

I'm a big fan of persisting almost everything in the primary database. With one exception: I'd immediately use object storage (S3) for files which are large in number or size. Files which are few and small (e.g. templates) are fin
