  • A wizard drops you on the moon. You immediately panic about not being able to breathe, plus your salivia is boiling and your blood is…well, it killed you pretty darn quickly.

    Thankfully, the wizard noticed and set spells that puts a tiny bit of atmosphere right over your head, and , repairs the damage inflicted already. There is a chair and a go-board in front of you.

    “Wait, that’s it?” you ask the wizard after he explains what the spells did. “Arent I going to burn, or freeze, or something?”

    “Eventually, yeah,” says the wizard as he sits down. “But the human body’s great at homeostasis. Since your blood isn’t boiling it can circulate heat within you, you can burn calories to add heat as needed, and sweating is absurdly effective since the relative humidity of a vacuum is pretty much less than zero.”

    “But, didn’t the Apollo capsule spin to manage heat, and aren’t there huge radiator fins on the ISS so they don’t slowly burn? I thought managing heat was hard?”

    “It is. For an inanimate object. Especially one that isn’t filled with water or surrounded by a thermo exchange medium. You ever see a capsule bleed or a probe sweat?”

    While 0 has no value and is often placed after 9 on keyboards, you asked about digits in a base and not numbers. This becomes clear if you describe the various bases.

    • Binary is 0-1
    • Octal is 0-7
    • Decimal is 0-9
    • Hexadecimal is 0-F

    If you sort zero at the end, you’d need to spell out the digits or label them all as 1-0, which isn’t very descriptive.

    Mind you, “zero-first ordering of digits” is not a fundamental rule, since the glyphs only have a need to be sorted when they stand for a numerical value . And if you used a phrase like “first X digits” without noting a range the omission would be a composition error.



  • Are there any real-world examples where encryption backdoors have been successfully used without compromising cybersecurity?

    No. Adding a backdoor to cybersecurity is fundamentally introducing a vulnerability that can be exploited by an attacker.

    A backdoor in your IT security is like a hidden button to bypass the lock on the impenetrable front door of your impenetrable house. Sure, it makes the police serving a warrant easier, but now there’s a button that anyone can push to bypass your door.

    What you will find are instances with no apparent violations. Just like setting all the nuclear weapons to have the exact same easily remembered activation code didn’t actually lead to a nuclear exchange.






  • I think it’s a good idea to foster a social place, or places,.where you just go to talk. Be as kind as humble as you can, and just post new topics you want to talk about or on-topic replies to things that seem interesting. The Mastodon / bsky model is probably a little better than Lemmy in this regard, since the basic unit is “account” and not “subreddit”.

    And I obviously have no idea what we call these things on Lemmy. What do you think they should be called?









  • This is a bad take on identity politics, unless you “identify” as a jerk who doesn’t care about others and wants to be sexist, transphobic, or racist.

    Identity politics is “we should organize people based on how they categorize themselves”, and that’s bad for a whole list of reasons but not any of what you said.

    The thing you’re talking about really does exist, but I think “you must change who you are” may have a more precise name.

    I think that “puritanical”, “tyrannical”, or “bigoted” politics may be more accurate.


  • No, the executive CANNOT arbitrarily convict anyone. In fact, the whole grand/petite jury system exists specifically because we assume that the administration might be a petty tyrannical jerk.

    The key feature of American federalism isn’t the polite myth that is “rule of law”. No country is,since the laws are all dependent on people to carry them out. Instead,it’s “separation of power”.

    Trump is going to do terrible and shameful things, as Biden did terrible and shameful things, but the ultimate check on his would-be tyranny will be the greed and pride of the Republicans in Congress and on the court.



  • So, EVERY radio on the planet is suddenly overwhelmed by broad-spectrum jamming from orbital sources? Every cell phone, wifi, broadcast TV, satellite, AM/FM?

    A bunch of people die,.due to distracted-driving car accidents with no way to call for help. News and government adapt modestly quickly, since the Internet itself runs mostly on already-shielded wires. There is a run on ethernet cables and phone modems for a bit, though, since not everyone has one. Navigation and timekeeping get harder, since no GPS or radio time sync, but humans adapt to those fairly quickly.

    Long-term consequences depend on how long the aliens keep it up. It’s definitely a holy crap there are aliens! moment, though, since a bunch of sudden radio transmitters would be detected in the sky and identified as alien tech way before the toilet paper shortage even starts.
