Sorta bullshit from the same lab that hyped their night time solar that works but is thermodynamically impossible to be practical.

Flash an ir diode with encrypted data and because encrypted data looks like noise, you can't tell that the data isn't just heat noise.

That's it.

They invented a bunch of hype words to get press because unfortunately that's how labs get money these days.

We're all the way back around to IR diodes now? Is this just early 2000s retro stuff, and we're going too get physical keyboards on our phones again soon?

My newish Xiaomi has an IR diode which is very useful to switch the AC on or off when I can't be bothered to find the remote, and to mute TVs in restaurants.

It has a 3.5mm audio jack too.

I used to love turning town loud TVs in bars back when IR blasters were common.

They invented a really neat diode. It creates electricity when it emits ir. But of course that isn't enough to get research funding which is why they make ridiculous hype.

Ok but that's a sick ass wallpaper

I feel like publishing it like this effectively neuters the security aspect…?

[-] mangaskahn@lemmy.world 34 points 2 months ago

Security by obscurity is no security at all. If you can't publish the details of a system and have it still work, it was never secure in the first place.

Tell that to Apple

And the United States government, whose nuclear launch systems for decades had a default "0000000" password on systems so old they figured nobody would know how to hack them in person anymore, and they're incompatible with the internet.

It's disturbing to me that my high school hobby of fixing and operating old computers meant I could have launched nukes.

It's disturbing that a lunatic with dementia could have nuclear launch codes

I think "finance" is even more obviously bullshit.
