SABRE is pretty good compared to the card file it replaced.


It's better to say SABRE replicated, in digital form, that card file. And even today the legacy of that card form defines SABRE and all the wrappers and gateways to it.


SDI is not really comparable. The numbers for the orbital parameters did not add up at the time, but they had Edward Teller behind them.


It's just a heavy metal umlaut for someone who could have written "state-level" or "country". Like forcing the word "geopolitical". I would not get too worked up about it.


The more recent US hegemony in radio communications technology was held by pioneering Bell Labs work leading to patented implementation as 3G standards. I think the US rested on the laurels of those patents for too long. Microwave RF basebands were not too long ago considered advanced as alien technology. Now China has re-developed them on their own terms.


Won't errors due to cosmic rays be an increasing issue at these process sizes?


You can't be sure what's in it these days, especially if it looks super professionally packaged.


thats unrelated to its classification


My bank just said that there was "no error" when I did this after Amazon failed to deliver something last year. I imagine that Amazon makes up a good portion of their chargeback complaints now.

Separately, I had my bank block Amazon Prime from charging my debit card. It shows up as a different merchant so they were do it and I can still make one-off purchases (which I don't like to any longer). I did this because the UI to cancel Amazon Prime did not work on my new, updated MacBook. It did not respond to clicks on the "confirm cancel" or whatever button.


Is church/temple out of the question too? Where do people go these days?


On a printed receipt at a restaurant, I once saw suggested tip percentages where the corresponding currency amount was greatly inflated and nowhere near the actual percentage.


It also has a vidicon tube for gathering images, although that can no longer be switched on.


Do we know the reason? Heater/cathode failure or HV supply would be likely reasons, or is there now insufficient power from the Pu source to run it?

(The HV supply on a vidicons is usually about 700V—that's high enough to be quite stressful on P/S components.)


There is a heater for the vidicon which had to be shut off due to power budget. This heater had been on since launch. After being switched off, turning on this heater back on, or the vidicon's cathode filament (itself a separate heater) would have cracked the tube due to the cold of space.


Yes, to save power. But there's nothing to photograph out there.


Makes sense, nice to know it wasn't due to failure.
