True, in that case it should just adopt the noexcept status of the object it holds.

I would argue performance-noexcept-move-constructor should always be on. Move constructors should almost always be noexcept since they typically just move pointers around and don't…

The scale and stakes of the investment now are much, much higher now than in dot com. Likewise, don't assume I'm more bearish than I am. But enormous investment requires more benef…

Quite a large bubble. The burden of proof for demonstrating the enormous economic value LLMs are providing really is yours. Sure, there are anecdotal benefits to using LLMs, but we…

I'm not saying LLMs are useless. But the value they have provided so far does not justify covering the country in datacenters and the scale of investment overall (not even close!).…

Firstly, it's not really good enough to say "our employees use it" and therefore it's providing us significant value as a business. It's also not good enough to say "our programmer…

The thing that drives me crazy is that it isn't even clear if AI is providing economic value yet (am I missing something there?). Right now trillions of dollars are being spent on …

Related to this, I've been wondering how much we should actually be depending on RLS for. There are known timing attacks against it [1]. [1] https://www.cs.tau.ac.il/~mad/publicati…

Yes, that's true. And not even ClickHouse considers their MergeTree engine to be an LSM-tree (see https://github.com/ClickHouse/ClickHouse/blob/bfc0260f359a0c... ). That doesn't ma…

I actually think you're describing a WAL.

The original purpose of an LSM-tree is to take I/O off the critical path of a write (there are other reasons to use them though, for example reducing space amplification). I would …

LSM-trees do need a WAL. The entire idea of LSM-trees is that writes are buffered in memory and written out all at once. But a particular write doesn't wait for the memtable to be …
