    IIRC, on the Z-80 peripherals where I/O space mapped using IN and OUT instructions, not memory-mapped (aside form the screen).

    We picked solid fuel _thermal_ neutron reactors, not fast neutron reactors. We also picked ceramic fuel, which complicates heat transfer and is subject to cracking.

    Except that they are intended to just be thrown away.

    There are no special disposal instructions for ionization smoke detectors. They may be thrown away with household trash, however your community may have a separate recycling program.

    The alpha from Am241 will not be detectable at any distance from the detector even if the metallic/ceramic enclosure is breached. The mean free path of an alpha particle in air is very small - about 5 cm.

    It wasn't the people that killed it, it was the studios. They were afraid Divx would cut into their DVD sales. From the article:

    Many people in various technology and entertainment communities were afraid that there would be DIVX exclusive releases, and that the then-fledgling DVD format would suffer as a result. DreamWorks, 20th Century Fox, and Paramount Pictures, for instance, initially released their films exclusively on the DIVX format.[5] DIVX featured stronger encryption technology than DVD (Triple DES), which many studios stated was a contributing factor in the decision to support DIVX first.[6]

    Today the studios are scrambling for cash and are much more likely to embrace streaming/encrypted media. They trust Netflix, and need a new way of selling us the same media. Remember that DVDs and blurays were 'secure' - ,a href="https://en.wikipedia.org/wiki/Advanced_Access_Content_System">supposedly blurays can revoke media keys. It's not a big stretch to go from having the encrypted media on a bluray to downloading the encrypted data. As long as the key escrow is secure (this is what Netflix brings to the party), having you pay for distributing their content makes sense.

    Which is hilarious, because this is exactly the same business model as the Circuit City Divx service! The disks were encrypted and you paid a small fee to unlock the files for 48 hours after your initial viewing.

"But once you have set it up, the operating costs are not much and more importantly, the environmental costs also go down. Good on your pockets too in the long run."

    Don't quote Nyquist, quote Shannon. Nyquist only applies to the minimum sampling rate for an unaliased time domain signal, not directly how much information can be transmitted in that bandwidth. There are plenty of encoding schemes that get multiple bits/baud.

    The Tsar Bomba TEST yielded 50MT. That was because it was missing it's outer uranium boost blanket that would've made it dirty as sin but a full 100MT.

    I quote:

    The initial three-stage design was capable of yielding approximately 100 Mt, but it would have caused too much nuclear fallout and the plane delivering the bomb would not have enough time to escape the explosion. To limit fallout, the third stage and possibly the second stage had a lead tamper instead of a uranium-238 fusion tamper ...

    More likely "making them harder to be noticed by the people they're spying on". If I hear a plane constantly buzzing everywhere I go, I'm gonna get suspicious.

  18. The oft-overlooked part of this is all of the infrastructure needed to manage the sats once in orbit. There are only so many earth stations and only so much TDRSS satellite bandwidth available.

    Also, by the time a satellite is finished, technology has usually outpaced the onboard systems and made it illogical to duplicate the original sat.

    Not exactly true. There seems to be a relationship between the fall rate and latitude.
