@cstross every cop and federal agent adopts it as part of their uniform in 0.02 seconds

@cstross It's a great idea, but now I'm thinking of just having a rickroll tee

[meyerweb@mastodon.social]

@cstross So a reverse Scorpion Stare, of a sort. I dig it.

@cstross Yes, please.

@cstross I got this shirt. Sadly it does not work as well as one would think it would.

@nblr @cstross Unless someone wants to photocopy a photo of it!

[sabrinaweb71@sociale.network]

@cstross and please sign me up, I want one too

@neurovagrant @cstross @unknownbinaries Woah! Anyone able to find a source in Europe?

@Angle @cstross Are there phones that will do that automatically? The most I've ever seen is where the camera automatically detects and interprets the QR code, but if it's a URL you have to tap on it in order to actually point a browser at it.

@cstross Every time I see something like this I think to myself, Monty Python‘s “The Killer Joke” seemed like such a silly idea at the time…

@neurovagrant @cstross @unknownbinaries I wish that provoked something stupider than a web search, though.

BTW please enjoy:

@anotherdaniel @neurovagrant @cstross @unknownbinaries could probably make one on any online print shop...as long as their systems don't try to read the QR code and then quarantine themselves!

[trainguyrom@techhub.social]

@nblr @cstross I'm guessing that's the pattern of yellow dots on US Currency to prevent scanning it?

[imsop@tech.lgbt]

@cstross I can't think how to search for it now, but I remember reading a while back someone went to a convention wearing makeup designed to defeat autofocus algorithms, and watched people frowning as they tried to take photos of it.

@cstross Shades of William Gibson's "Ugly t-shirt" from Zero History. Papers were written...

@cstross Max Gladstone wrote something similar in Empress of Forever... QR code face paint to hack a security camera

[scurra@mastodon.social]

@cstross I'm now wearing a badge on my coat that is a QR code which links to a page on my personal website that (currently) says "by photographing/filming me without permission, you agree to pay me an appearance fee of £100." It's obviously an empty threat, but hey, I felt like I needed to do something.

@neurovagrant @cstross @unknownbinaries How big a zip bomb can you get in one, anyway? And can you fit the EICAR string in an unpleasantly long way in?...
