I can’t tell you how relieving it is to hear somebody else complain about this. This has been my pet peeve for ages.

Well, this has sucked up a couple days of my free time so far... :)

New comment by bradfitz in "OpenSCAD is kinda neat"

bradfitz — Sat, 20 Dec 2025 18:29:45 +0000

I find myself using OpenSCAD regularly to 3D print little things for the house. (Most recently: hooks to attach Christmas lights to our roof deck's glass walls)

And when something gets too trick, ChatGPT is amazing at writing in it. Often it nails the whole design in the first try, like https://bsky.app/profile/bradfitz.com/post/3maelwomyw22n to mask off certain Raspberry Pi pins to make reassembly of projects easier later.

I seem to recall reading that as a kid too, but I can't find it now. I keep finding references to "Encyclopedia Brown, Boy Detective" about a Civil War sword being fake (instead of a Great War one), but with the same plot I'd remembered.

I've been idly following this stuff on & off for years, but I never saw proving a point "instead of using Rust" as one of the motivations of the project. Was that ever stated anywhere?

Until they start using Sidewalk/LPWAN type things automatically instead of your home WiFi.

I had to go look that up! I assume that's https://en.wikipedia.org/wiki/The_Feeling_of_Power ? (Not a janitor, but "a low grade Technician"?)

Related, I gave a 6 minute lightning talk about writing tests in Go that use the test binary itself as the PID 1 under an emulated Linux in QEMU:

How many of those additional 1,643 were a result of your 2014 blog post? :)

I assume it's intentional, playing on "libre" (as in libre software, not just gratis software)

I'm a co-author of tsidp, btw. You don't need tsidp with a Tailscale-native app: you already know the identity of the peer. tsidp is useful for bridging from Tailscale auth to something that's unaware of Tailscale.

Primarily using Tailscale for authentication as well, replacing perkeep's other auth methods.

Tailscale employee here.

I kinda doubt we'll end up charging for it (as it costs us ~nothing except support costs, which are real), but it's easier to make it free later when it's GA rather than rug pull on people and start charging for it in the future if we start it out free+unlimited.

It doesn't. But judging from forum posts, it seems like it was a common failure mode and it might've been fixed in later hardware revs.

I ordered three and they all worked and then one died. Fortunately they replaced it, though.

Go does. And it supports timeouts and cancelation.

Go strings are just bytes. There is no Unicode or encodings.

Nope. It’s just bytes with no encoding.

There's no WebRTC in Tailscale.
