我当了30年文学刊物编辑，见过许多憋着劲儿要“一鸣惊人”、结果连第一段都画不上句号的作者。写作面对的最狠的敌人是什么？不是文笔差，不是没想法，而是那个在你耳边嘀咕“这不行、那不够”的完美主义小鬼。它让你写了三句删两句，让你总觉得这句、这段“没写好”，最后留下一个完不成的“作品”，或者什么也没留下。

I’ll give you an example of what this looks like, which I went through myself: a couple years ago I was working at PlanetScale and we shipped a MySQL extension for vector similarity search. We had some very specific goals for the implementation; it was very different from everything else out there because it was fully transactional, and the vector data was stored on disk, managed by MySQL’s buffer pools. This is in contrast to simpler approaches such as pgvector, that use HNSW and require the similarity graph to fit in memory. It was a very different product, with very different trade-offs. And it was immensely alluring to take an EC2 instance with 32GB of RAM and throw in 64GB of vector data into our database. Then do the same with a Postgres instance and pgvector. It’s the exact same machine, exact same dataset! It’s doing the same queries! But PlanetScale is doing tens of thousands per second and pgvector takes more than 3 seconds to finish a single query because the HNSW graph keeps being paged back and forth from disk.，更多细节参见新收录的资料
Однако цены на нефть, считает экономист, все равно могут как расти, там и опускаться соразмерно обстоятельствам. «Например, если боевые действия также будут затрагивать нефтегазовую инфраструктуру ближневосточного региона, цены перейдут к росту, и не важно, что говорит американский лидер», — заявил эксперт.
