Comment Digital cameras didn't survive metal detectors (Score 0) 97

My early digital cameras didn't survive metal detectors. I got permanent stuck pixels on the sensors just by sending the cameras through the metal detectors.

Before you ask, we were not allowed to use lead-lined bags like we did with traditional film.

Can't wait to see those grainy, blurry, smeared images with stuck green pixels from the far side of the moon!

Comment Inspired by the Off-the-Record Messaging protocol (Score 3, Interesting) 26

Their encryption is inspired by, if not directly based upon, the Off-the-Record Messaging (OTR) protocol.

Being a public-key encryption protocol, OTR messages can have the session key encrypted by more than one PK key, meaning that more than just the user's intended recipient can read the data.

The "perfect forward secrecy" and "plausible deniability" are still in effect, but you have two Bobs in the Alice and Bob encryption model.

Comment I stopped subscribing when they added non-nuclear (Score 1) 69

I stopped subscribing when they added non-nuclear threats to their "Doomsday Clock."

I subscribed because I'm interested in nuclear issues. Since ten years ago, half the magazine is now about climate change, terrorism, war, unrest, immigration, etc.

They've lost their focus, for sure.

Comment Re:Summary convinced me not to read the article (Score 1) 56

That post had me wondering if my home heat pump uses impellers or just relies on the action of the compressor's pump for coolant circulation.

Based on the cold snap we're having in Virginia, the noise our heat pump makes when reversing to defrost the outdoor unit makes me think it's just using the compressor's pump and not an impeller or "fan."

Thanks for that insight.
