Given how many studies have built-in sampling bias or other surprising assumptions, I still welcome people gut-checking it vs their experience. (Plus, the stories are interesting, right?)

Having worked for a business that made a serious go of running everything out of stored procedures, I have to say that lack of version control was a huge problem and effectively limited all development to a single person who held all the rules in their head.

lack of version control, clunky language mechanics, performance issues, etc.

This has been tried, but thousand-line stored procedures are truly a nightmare.

The description of the interview seems like it was explicitly non-technical, though.

I mean, we're pretty deep into Westworld/Blade Runner-style scifi at this point. It's actually a crazy, mind-bending question to try to grasp what is going on with chatclaudini at this point. Regardless of what labels we choose or properties we choose to affirm, we're far too deep into uncanny valley for it to be very helpful.

LLMs often seem to have trouble determining the severity of a bug/incident/problem in a vacuum. If you run an LLM over 1000 items in parallel and ask "is this bad," it will come up with reasons for it to be bad way more than it might if it were considering all 1000 at the same time.

Scrolling down, a bunch of these seem to just be "the startup shut down after getting customers", which doesn't seem particularly scandalous to me?

Fair point that there might be some functional changes you can suggest, but I continue to suspect that by the time this PR hit GitHub, all the most important decisions have already been finalized.

First of all, redis is amazing, and your 4 month development process speaks to the fact that you've already designed and verified correctness super thoroughly.

... just speaking as someone who sometimes has to review very long PRs sometimes, though, I feel like 25% is a roughly normal level of "signal to noise." 5,000 lines of core logic is a LOT, and the tests and dependencies do still need to be read.

EDIT: I feel like the problem, as a reviewer, is processing 4 months of intensive research/development and providing useful feedback. At that point, there's probably not much major input you can have into the core architecture or strategy, so you're probably not providing much more than a bugbot at that point.

Oh wow, I didn't realize that Redis is still mostly just authored by antirez! (My understanding is that he had left for some time and then returned to the project.) That is, honestly, pretty amazing. Well, redis is great and clearly it's worked out.

I'm curious, do people around you use AI? Because in my own workplace, people use lots of AI, and they ship lots of PRs, which correspond to actual features on the roadmap. I've been doing this a long time, and there is a whole lotta stuff shipping. I'm a manager and in the handful of hours I have I'm shipping the equivalent of what I would have as a full-time eng years ago.

Reviewing 22,000 lines of code, even from antirez, with this complex of a feature set and minimal PR description sounds like a nightmare. One starts to see why major open-source software like Postgres tends to be developed on a mailing list, with intermediate design decisions discussed by the community, separate patches for different related features, incremental review, and then a spaced release cadence.

I was expecting to see some verbose LLM output, but actually the code has a distinctly hand-crafted feel. Nice to see! I'm not sure if "production ready" is a safe claim 7 commits in to a project ;)

tibbar — Wed, 22 Apr 2026 16:44:47 +0000

$8M sounds like a lot, but (a) the cost of making a material financial mistake c an easily dwarf this, and (b) the cost of the engineers maintaining the system was likely about this expensive anyway. And infra is expensive when you're Uber. It all seems rather overblown to me.
