Another great reason to use a custom, constantly shifting keyboard layout

I use blank key caps, and I find it leads to much more comfortable touch typing.

Slower, sure, but cozier also

Why would blank keycaps matter for touch typing

[–] [email protected] 11 points 2 months ago

It's just a question of matching pattern with most used words against languages...

[–] [email protected] 20 points 2 months ago (2 children)

The article doesn't mention how it compensates for different keyboards. Like wouldn't different switches and wear change the sound?

[–] [email protected] 22 points 2 months ago

That's because it's Wired. Basically a big ass advertisement.

It sounds like bs but its cause that's been solved since around Roman times, heres a pretty interesting website on the technique

Dude in the thumbnail looks like an un-and-coming Bond villain.

Dude in the thumbnail is Samy. He's been a bond villain for a long time now.

Laughs in DVORAK. This is some pretty funny Schitzotroll.

[–] [email protected] 11 points 2 months ago (1 children)

it's heuristic, so it doesn't matter what layout you use.

My keyboard is loud enough that it can be heard that far away anyway

Make it a UV laser and it would be invisible.

[–] [email protected] 32 points 2 months ago (3 children)

demonstrating that he can point a laser that's invisible to the human eye at a faraway laptop, through a window, and detect the computer's vibrations to reconstruct virtually every character typed on it

Infrared is not visible

[–] [email protected] 10 points 2 months ago (1 children)

It is visible to security cameras

[–] [email protected] 1 points 2 months ago

Ahh ok, that's what you meant before I guess

Since that function is usually meant for night vision, I wonder how well a security camera can pick out the laser during the day i.e. when the IR sensors are being swamped by daylight also coming in through the window

[–] [email protected] 3 points 2 months ago (2 children)

Infrared doesn't pass through windows.

[–] [email protected] 3 points 2 months ago (3 children)

actually thats UV. transition lenses won't change with a glass window thats not open. infrared is basically heat and does indeed pass through. Cars in the sun would not get hot so fast if they did not let in infrared.

[–] [email protected] 2 points 2 months ago (1 children)

I have an IR camera and windows look like mirrors. Might depend on the type of glass idk.

[–] [email protected] 7 points 2 months ago (1 children)

if this yahoo from the internet I found in a search is right then its both:

"Glass will bock low frequency IR (red hot), but allow the passage of high frequency (white hot) IR. Hence, the heat of the sun will easily pass into a greenhouse, but once this energy is converted into low frequency heat by the objects within that absorb it, then the resulting low frequency heat is trapped. Hence, the Greenhouse Effect."

That makes a lot of sense, thanks for doing the homework!

Infrared is not visible

To humans

[–] [email protected] 17 points 2 months ago

It's already infrared. Also, UV is partially visible to humans in some scenarios.

And perhaps he was named Billy

And perhaps he has a willy.
Uhm... what was the topic again?

Great, now hackers and spies can detect my typing instead of using RATs or Trojans or packet sniffers, or just beating me with a $5 wrench (XKCD)

Also:

The trick, which takes advantage of the subtle acoustics created by tapping different keys on a computer, works even without a view of the computer's keyboard, so long as the hacker has a line-of-sight view of any relatively reflective portion of the target laptop.

So... Closing the curtains is all it takes to defeat this amazing technological method. GG.

[–] [email protected] 3 points 2 months ago* (last edited 2 months ago) (1 children)

I'm not sure why you're so dismissive of this? It's kind of asinine.

Does everyone everywhere only ever use computers in an enclosed room? Is everyone with something value to exfiltrate easily accessible to kidnap and beat with a wrench?

This is valuable for corporate espionage, political purposes, or for nation states. If miniaturized, even easier for targeted attacks where it might be difficult to inject malware, or for broad attacks on office workers.

And the best part is that it doesn't leave a trace which beating someone with a wrench and malware would do....

Came to find out about the audio quality of this exceptional microphone.

:(

[–] [email protected] 1 points 2 months ago

Random unrelated thought I just had, can you guys think of any interesting musical applications to a laser microphone? I found this super cool video when I tried to look it up (there's practically nothing)
