Prompt regurgitation. Model was likely instructed to create the app to do this piece "by hand" (or a phrase with similar interpretation) because the author wanted to avoid pulling in a dependency of some kind.

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

codys — Fri, 10 Jul 2026 01:14:21 +0000

It'd be very unfortunate if Postgres didn't have regression tests for data loss due to bad io patterns. Should be possible to do some checks against those in an appropriate test harness. Which might mean "have qemu run something we can kill off and examine the results".

If those don't exist, I hope folks recognize how useful they are and add them.

Yes, I agree it would be very nice to have a way to integrate ACME into zeroserve. I'm not sure if zeroserve's plugin system might allow one to add a plugin to support it?

zeroserve doesn't use the Linux kernel's eBPF runtime to run the eBPF it uses, so the constraints of the Linux kernel's eBPF runtime (chosen because of how the Linux kernel thinks about protecting the Linux kernel from user space) don't apply to zeroserve (or other tools that use the eBPF instruction set but don't use the Linux kernel's particular implementation)

I hope this signals a departure from us being stuck without web usb in firefox too. It's a shame that I've been stuck using chrome for it.

And maybe we'll get web bluetooth too.

I think their site is just slow, potentially because more people than they are used to are trying to view it.

I was unable to load it initially (got an error from firefox) and had to re-attempt. Still slow if one forces a reload (shift-r, etc, to not use local cache).

New comment by codys in "BYOMesh – New LoRa mesh radio offers 100x the bandwidth"

codys — Mon, 04 May 2026 03:08:41 +0000

The idea with either requiring very wide band or frequency hopping on the 900Mhz band is to make it so that usages of the 900Mhz band 1. are tolerant to some loss (ie: by temporary collision) and 2. don't collide continuously (by using wide band or frequency hopping).

It's a mechanism to try to make the 900Mhz band more useful to uncoordinated users.

The Apple way for hardware is more to design the thing so it breaks under normal use very quickly, and then refuse to replace it under warranty.

It's not a leading colon: It is a colon separator between the username and password, and the command used has the username as an empty string.

> Also, the "obvious reason" that American politics sent zero ex-presidents to prison is that Biden chickened out. So, there's that.

Don't forget Ford deciding to protect his political allies (by pardoning Nixon). And George HW Bush doing similar (preventing Iran-Contra scandal investigation by pardoning participants who could have fingered Bush or Reagan)

I'm not sure I follow. This outage seems like it occurred for less than 1 day. The post you link to is about having certificates expire after 45 days. What's the connection you see?

Seems you could use a single SQL statement for that particular formulation. Something like this, using CTEs is possible, but alternately one can reformat them as subqueries. (note: not sure how the select of orders is intended to be used, so the below doesn't use it, but it does obtain it as an expression to be used)

    WITH
     o AS (
      SELECT FROM orders
      WHERE orders.id = $1
     ),
     os AS (
      SELECT FROM orderStatuses
      WHERE orderStatuses.orderId = $1
      ORDER BY DESC orderStatuses.createdAt
      LIMIT 1
     )
     INSERT INTO orderStatuses ...
     WHERE EXISTS (SELECT 1 FROM os WHERE os.code != $2)
     RETURNING ...something including the status differ check...

Does something like this work with postgres's default behavior?

Garbage collection is not required for memory safety.

Languages that have garbage collection are not all memory safe.

It seems like the messenger might endorse the message though, and is attempting to be coy.

Folks should be careful of people using the "messenger" title to attempt to obtain the appearance of impartiality.

I believe google, who maintain chrome and are on the CAB, are an entity well known for hosting various websites (iirc, it's their primary source of income), and those websites do use https

OpenBSD does start X. And subsequently OpenBSD apparently hangs (or did so previously) when OpenBSD was running under Qemu.

The subject in the parent comment changed to OpenBSD when they mentioned it, and it appears you may have overlooked the subject change.

Possibly a better comparison (though a bit dated now) would be AT&T (or whatever telephone monopoly one had/has in their locality) charging an additional fee to use a telephone that isn't sold/rented to them by AT&T.

New comment by codys in "Show HN: BusterMQ, Thread-per-core NATS server in Zig with io_uring"

codys — Thu, 01 Jan 2026 15:25:33 +0000

> I am assuming the message durability guarantees lean towards YOLO rather than ACID?

"Core" nats doesn't have durability. Nats jetstream is the api built on top of nats that in the main nats-server impl provides durability. Jepsen tested Nats Jetstream.

Also from your link:

> Regular NATS streams offer only best-effort delivery, but a subsystem, called JetStream, guarantees messages are delivered at least once.

The project linked here does not implement the nats jetstream api, just normal nats.

So yes, it seems its same (documented, understood) "yolo" as normal nats.

It seems it's just a part of a doc on style in tigerbeatle, in a similar way to the various "Google Style Guide" for code. These rarely have something new, but document what a particular project or organization does with respect to code style.

New comment by codys in "Memory Safety"

codys — Fri, 26 Dec 2025 15:44:32 +0000

You've linked to a bug that was unintentional and was fixed.

Go allowing torn writes for their slices and interfaces (their fat pointer types) is intentional behavior in the go implementation and has no sign of being fixed.

Some one getting unsafe code unintentionally wrong is not an indication that any language lacks memory safety.
