Sometimes I think the RFC editors are trolling us.

This sounds an awful lot like https://en.wikipedia.org/wiki/Company_scrip, which has been illegal for a long time and for good reason.

Is laser printing more feasible? I've had the same Brother black & white laser for almost a decade and it's more than adequate for everything I do. If I ever need color, I send it off to a service that has much nicer printers than most people would ever want in their homes.

> If you encountered a cheetah in pre-industrial times (and survived the meeting), you might think it was impossible for anything to go faster.

Fun fact, there is no historical evidence of an adult human ever dying from a cheetah attack. They are naturally shy, and a lot smaller than you may realize.

New comment by jelder in "Show HN: Semble – Code search for agents that uses 98% fewer tokens than grep"

jelder — Mon, 18 May 2026 11:36:21 +0000

LSPs are already miles better than grep-like tools. This was true for humans as much as it is for LLMs. It's a shame that Claude still treats it as a second-class citizen (both in the app itself and in the training). A simple "remember to use LSP instead of grep" is usually enough to get it on the right track.

New comment by jelder in "If AI writes your code, why use Python?"

jelder — Tue, 12 May 2026 13:50:24 +0000

There's a huge difference between a program which can be verified as correct by static analysis, and a program which can only be verified as correct by running it. Python is the latter (though maybe in between with gradual typing). The iteration loop just collapses when an agent is driving an LSP in a statically typed language.

jelder — Thu, 26 Mar 2026 12:02:26 +0000

Who goes out of their way to “star” a GitHub repo, and what does that even mean? Is it a “like” button, a tip jar, or a bookmark? Does this bare any relationship to the importance, quality, novelty, trustworthiness, or any other property of the repo other than number of stars?

What a dumb metric to focus on.

New comment by jelder in "We give every user SQL access to a shared ClickHouse cluster"

jelder — Sat, 21 Mar 2026 12:42:15 +0000

We did this with MotherDuck, and without introducing a new language. Every tenant has their own isolated storage and compute, so it’s trivial to grant internal users access to specific tenants as needed. DuckDB’s SQL dialect is mostly just Postgres’ with some nice ergonomic additions and a host of extra functionality.

New comment by jelder in "Pipelined Relational Query Language, Pronounced "Prequel""

jelder — Mon, 23 Feb 2026 16:31:03 +0000

DuckDB had the right idea: just allow some flexibility in the relative order of the `select` and `from` clauses, and make a few other concessions for ergonomics. This then becomes valid:

    from events      -- table is first, which enables autocomplete
    select
        count(),     -- * is implied, easier to type
        customer_id, -- trailing commas allowed everywhere
    group by all     -- automatically groups by all non-aggregate columns
    order by all     -- orders rows by all columns in selected order

You can't trust a product that uses ads, because then you are the product.

If you were to rank all of the C compilers in the world and then rank all of the welfare systems in the world, this vibe-coded mess would be at approximately the same rank as the American welfare system. Especially if you extrapolate this narcissistic, hateful kleptocracy out a few more years.
