I just get a flat floating image of a black hole. Am i holding it wrong?
All password managers support passkeys.
Both apple and google allow exporting your existing passkeys to third party password managers too.
Also each website gets it's own unique public key with passkeys. It isn't a single credential
You're literally arguing a strawman
Skill issue on promoter side.
Fable oneshotted it for me.
""" Reveal a motion-camouflaged message hidden in video noise.
How it works: The background noise scrolls vertically at a constant rate (a few px/frame), while the noise inside the letters does not follow that motion. Any single frame looks like pure static. The decode is:
1. Estimate the background's global motion between consecutive frames
with phase correlation (this is the "optical flow" step - the motion
is a pure translation, so one global vector suffices).
2. Motion-compensate: shift frame t+1 back by that vector so the
background lines up with frame t.
3. Take the absolute difference. The background cancels almost
perfectly; the letters (which don't move with the background)
light up.
4. Average the residual over a SHORT window of consecutive frame pairs
(long windows smear the letters, because the text itself drifts
slowly over time), blur lightly, and threshold with Otsu.

Residency is purely about taxes, health insurance and right to work. You e.g. don't get voting rights in national elections.
EU citizens automatically get permanent residency in any EU country regardless of language.
E.g. I'm a permanent resident in Germany as a Dutchie.
(However I did end up picking up German and speak it now. But never had to do a language test)
The whole point is that it allows introducing controlled side effects as long as the output is reproducible.
Bur you're extremely annoying to talk to so I'm not gonna continue engaging. Probably an LLM
This is just a mechanism for the builder to inject credentials during fetch time. The derivation is still content addressed (it's a fixed output derivation).
The derivation isn't even marked as impure or whatever. There is just an environment variable that gets injected by the builder into the build env so you can authenticate.
This is required to talk to hugging face
What are you on about?
Or do you mean that the cas address of HF should directly be addreessable in nix itself?
They do not.
Now I have two CI providers to replace by the end of the Quarter
Sigh
For example we gesture when something tastes good and I don't even say "tastes good" out loud i just wave my hand next to my cheek. But quickly learnt that people think you're crazy in the head instead of complimenting the chef.
Looking into switching today :D
The quest being much lighter makes it nice though (but you should buy a third party headstrap that doesn't suck)

I made a Prometheus exporter for it:
The only way I found out is because I run NixOS and it downloaded a dynamically linked binary that failed to start up and it spat out an error
Arguing for html on a platform with less rich semantics than markdown is just ultimately funny

Yeh. But wire's storage is based on Cassandra which handles replication of storage. So you could deploy it on local nvme drives as well using a local storage CSI.
That's also how the wire.com cloud is/was run. Large Cassandra cluster on top of EC2 Instance Store as opposed to EBS.
I was actually on site at the Bundeskanzleramt and they had requirements of being able to install the entire server stack airgapped. We ended up building quite a cool delivery method based on Nix to ship the whole closure of the system and the containers inside and spin up a Kubernetes cluster with it. I'm wondering if it is still being used.
Amazing to see it's still going strong :)
They dont have a service usage problem they have a slop problem. Ban the slop and the platform will thrive
