Played a bit around with the #Minolta #Dimage7 which I finished repairing a few weeks ago...

The image sensor, which is more than 20 years old, shows some clear #HotPixels @ longer exposure times, but I can tolerate that. I just have to take a few 'empty' black pictures to filter out and everything will be fine. :wink:

And yeah, I love the Dimage7's fucking old macro lens! 🀩🀭

"...researchers' #hotpixels attack forces one of the variables tracked by DVFS to remain constant. By monitoring the two other variables, they were able to determine which instructions were being executed..."

'Hot pixels' attack steals data through CPU readings

A team of security researchers at Georgia Tech, the University of Michigan and Ruhr University Bochum in Germany has reported a new form of side-channel attack that capitalizes on power and speed management methods used by graphics processing units and systems on a chip (SoCs).

Uh, asking for a friend ... what would happen to a thermal imaging sensor if you accidentally sent it through a radiation sterilization chamber?
