New comment by ahlCVA in "The USB Situation"

ahlCVA — Sat, 02 May 2026 11:21:27 +0000

Apple implements the USB-C/USB PD specs to a t and is unforgiving if you don't do either.

At work, our quick test for if a device implements USB PD correctly is to plug it into an Apple power supply (optionally with a PD protocol sniffer in line). If it doesn't work (either no/intermittent VBUS or the wrong VBUS), it's always been the case that the device is doing something wrong.

It can be annoying but strictly speaking their fault.

You're probably taking the wrong painkiller

New comment by ahlCVA in "IPv6 is not insecure because it lacks a NAT"

ahlCVA — Wed, 21 Jan 2026 13:38:17 +0000

Obviously the two aren't the same (especially given the need to do routing), but I've always found it amusing that in the systems world, capability-based systems (i.e. making it impossible to address things you aren't allowed to access) are gaining traction while the philosophy in the networking world seems to be going in the opposite direction (make it possible to address everything, i.e. IPv6 vs. NATted IPv4, then add filtering).

New comment by ahlCVA in "Bose open-sources its SoundTouch smart speakers ahead of end-of-life"

ahlCVA — Wed, 07 Jan 2026 19:04:15 +0000

Calling publishing API docs "open-sourcing" is a bit hyperbolic, but as token gestures go, it's at least worth a little bit.

I'm not familiar with those devices in particular, but I wish vendors would take steps to make life easier for after-markt firmware developers especially once devices go EOL by doing things like proactively dropping a GPL tarball and giving people a way to disable secure boot locks on devices that have them.

New comment by ahlCVA in "Gpg.fail"

ahlCVA — Sun, 28 Dec 2025 23:47:19 +0000

This is a per-credential setting, so you can have your SSH signing key be a no-touch key and still use touch confirmation for everything else.

(see "uv" option here https://fidoalliance.org/specs/fido-v2.0-ps-20190130/fido-cl... - the -sk key types in SSH are just a clever way of abusing the FIDO protocol to create a signing primitive)

For what it's worth: You can set no-touch-required on a key (it's a generation-time option though).
