New comment by up2isomorphism in "Making Postgres 300x faster for analytics: batching, operator fusion, and SIMD"

300x if it is true you will be just busy dealing with you customers rather than pitching here. Also since it is a vibe coded project, if you are really that good , you should even need to related yourself with Postgres. Who will want related itself to something that is 300x slower than itself?

Coming from a country where almost everybody rides a bike. I would say US is the worst place to ride a bike. Also the utilization is inherently low due the city layout and weather is bad in winter in most US cities. It would be much more efficient to use the space for bike lanes for better pubic transport.

If actually anyone noticed, then it is a pretty bad move. Also “going well overall “ does not answer the author’s observations either.

The statement is weird, of course it is aiming at replacing bun, and it might not be a bad thing. Not sure what that clarification serves.

1.5B is a joke

The results are great. They will still need to post the detailed chat session to show how AI is helping though.

This is not really true considering Apple and nvidia are two most successful hardware companies, and they are notoriously closed. Not to mention microsoft, oracle they are all pretty closed.

I think there will be soon a wave of rewriting rust to language X coming up.

This is a very wasteful way of getting communications to somewhat compensate the lack of competition in US telco market.

You are exactly depicting the problem of the rust culture.

New comment by up2isomorphism in "Postgres rewritten in Rust, now passing 100% of the Postgres regression tests"

up2isomorphism — Fri, 10 Jul 2026 07:40:12 +0000

300x is mostly a marketing term, especially without the test description.

BTW, showing no respect to what it is trying to copy looks uncomfortable.

It is very bad metric to measure a rewrite using the original tests. It is like to say you clone a cat by mimic 600 cat images.

Then the question is why? Because that is an another way of saying donating tokens.

It depends on how inequalities is defined. But from the wealth distribution point of view, today’s wealth distribution skews much more towards the top. Although the lowest living standards improve thanks to the technology advancement.

New comment by up2isomorphism in "Epoll vs. io_uring in Linux"

up2isomorphism — Sun, 21 Jun 2026 01:03:32 +0000

The author takes a very benchmark focus on this topic which only says part of the story particularly for complex systems. Noticed that there are a number of very similar interface that exist on other platform like windows long before io_uring, but that does make Linux’s I/O system worse or slow than these platforms. A fast server is likely fast in either multiplexing or async API if implemented correctly in almost all cases.

There is really nothing free in terms of money, there are only things really free in term of spirit. But AI coding assistant are not those things related to spiritual freedom.

The comment under this kind of post is unreadable now. Yeah, probably with 100B you can hire anybody to call something "a beast".

This is totally understandable from human’s perspective. On the other hand this is a result of global market and trade and most importantly growth based economics. So it is very hard to cure a problem by removing the symptoms.

Actually it almost serves like an anti-features to me.
