Actually AI is a place where TCP works mostly fine, due to its bandwidth limited nature rather latency limited.

The really problem of iPhone camera is not these benchmark things. The problem is that the photo captured by the “Modern iPhone” simply does not look nice , let say, compared to iPhone 4S.

So do we observe overall Microsoft software quality improvement so far?

up2isomorphism — Fri, 28 Aug 2026 17:57:26 +0000

Funny thing is that the major reason most people use musl is because glibc make it (artificially) hard to do completely static linking.

It is not misleading at all. For all these softwares, the team that behind is the most important part rather than the software itself.

Just use C, these are well understood things 20 years ago.

The deep problem is that insurance is a highly profit driven business in the US which basically go against what a good insurance should look like.

Ubuntu has not been famous for robustness as a distribution. It seems the tastes is a major factor as seen in this case.

Hardware is so far nowadays to make people with little systems knowledge confident to make such claims at least from their use cases. However it is neither generally reasonable nor efficient.

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

up2isomorphism — Fri, 07 Aug 2026 23:29:51 +0000

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.

New comment by up2isomorphism in "How is the Bun rewrite in Rust going?"

up2isomorphism — Mon, 27 Jul 2026 21:23:44 +0000

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

up2isomorphism — Thu, 23 Jul 2026 22:15:11 +0000

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.

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.

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.
