A science fiction novel I'm reading reminds me of one of my least favorite authorial contrivances in that genre. Our heroes' spaceship assumes standard orbit around an alien world, they start listening to electromagnetic traffic, and more or less instantly start getting video of the aliens below. No. No, it's not going to work that way, not at all, unless you arrive during a ridiculously short window after the locals invented radio. This assumption is a hangover from the analog technology of my youth. The problem is that it's highly unlikely that the locals are still using analog audio and video. If they were, this contrivance is reasonable. There are only a limited number of ways to do that, and it shouldn't be all that difficult to deduce the parameters from looking at the shape of the waveforms. Once they've gone digital, though, all bets are off. There are huge number of possible ways to write digital audio and video codecs, and you can't figure out what encoding is being used from the shape of the waveform. The really good ones look like white noise, because the better your video compression is the more statistically random the compressed blocks are. Aliens arriving in orbit around Earth today would still be able to crack audio with passive listening, because broadcast radio has not gone to spread spectrum digital. But the window for video started closing in the first decade of this century and is now pretty much shut. There's no way around it. Your visiting spaceship is going to have to capture a local video receiver, peel the hardware, and disassemble the firmware. This is not a particularly difficult task, but it is one that requires getting up and close and personal with alien artifacts. Okay, I'll stop waving my cane now.


Russia and its pathetic supporters want you to forget this: Prigozhin destroyed Putin’s fake justifications for the war in a video released before his coup attempt

Exclusive: A year after Tenet Media was busted for funneling Russian money to MAGA pundits like Benny Johnson, a Trump administration effort involving State and the FBI has welcomed Tenet's founders back into the US. @BulwarkOnline: thebulwark.com/p/lauren-chen-…
