  • Circadian rhythms aren’t based solely on the sun. They are also based on social and physical activity. Things they don’t get when sitting indoors for the entirety of their daylight hours.

    Lack of sleep is primarily because they are not physically tired come bed time. They aren’t physically tired becauae they haven’t engaged in any physical activity all day. They’ve been obligated to sit indoors during daylight hours, and they don’t have daylight for outdoor evening activities.

    Instead, they get to sit indoors, under artificial lighting and watching bright screens, both of which screw up their sleep schedules.

    DST is in use 3/4 of the year. It is “normal” time, where everyone recognizes that 4am is entirely too fucking early for a sunrise, so we push that back to 5AM.

    “Standard” time is the abnormal abomination that we currently switch to for about 3 months in winter.

    Seasonal depression in kids and teens is primarily due to the lack of outdoor activities in winter, which is caused by an abnormally early sunset driving them indoors immediately after school.

    Locking the clocks on normal, “summer” time solves the problems with the time change. The “kids walking to school in the dark” problem is mitigated by the fact that they already spend the darkest three weeks of the year on winter vacation; we can extend that one more week by stealing three days from each end of the summer vacation. The remaining two or three weeks of early morning darkness do not justify stealing months of evening daylight from the rest of us.


  • (Buffalonian bison) (Buffalonian bison intimidate)] intimidate (Buffalonian bison).

    [(Albany cattle) (Utica bison bully)] intimidate (Syracuse oxen)

    [The] Albany cattle (that Utica bison bully) intimidate Syracuse oxen.

    In this sentence, “cattle” are the subject, and “oxen” are the object. The verb is “intimidate”. Everything else is some form of adjective modifying “cattle” or “oxen”

    We can go further:

    [The] Albany Cattle (that Utica Bison bully) intimidate [the] Syracuse oxen (that Poughkeepsie yak deceive).

    Cattle are still the subject; Oxen are still the object.

    The cattle (which are bullied by the bison) intimidate the oxen (which are deceived by the yak)

    Moving on:

    [The] Albany cattle (that Utica bison [that Buffalo buffalo buffalo] bully) intimidate [the] Syracuse oxen [that Poughkeepsie yak deceive].

    The cattle are still intimidating the oxen. Which cattle? The cattle that are bullied by bison. Which bison? The bison that are buffaloed by buffalo.

    Which oxen? The oxen that are deceived by the yak.

    The buffalo buffalo the bison; the bison bully the cattle; the cattle intimidate the oxen. Which oxen? The oxen which are deceived by the yak.



  • The reality is that “tactical” and “strategic” are functionally meaningless adjectives when applied to weapons or systems.

    Theoretically, “tactical” refers to how a military unit engages another military unit. It is how a commander wins a battle against an enemy unit.

    “Strategic” refers to how a nation engages another nation. It is how a government wins a war.

    The term “tactical nuke” referred to something that a lower level commander could have been authorized to use under his own judgment. If Soviet tanks were rolling across Europe during the cold war, commanders may have been granted the discretion to use small nuclear weapons to halt their advance.

    Since the the doctrine of Mutually Assured Destruction was established, there has been no such thing as a “tactical” nuke. Any wartime use of a nuclear weapon of any kind demands an escalation to total annihilation. I used the term “tactical” ironically, to refer to a pre-“MAD” doctrine that can no longer exist.

    In declaring that conventional bombs cannot penetrate this fixed bunker, it seems that someone is pushing for unconventional warfare. The reality is that this bunker is not impenetrable. It shares the same weakness as any bunker: getting into and out of it. Bomb the entrances to the bunker, and it will take months or years to tunnel back in. Whatever they are doing inside it, they won’t be doing until they manage to dig it up again.













  • You can’t make that round.

    I mean, you could. You’d need three times as many contacts in the receptacle as pins in the plug. Each pin would have to be able to touch exactly 1 or 2 contacts simultaneously. Each receptacle contact would need to programmatically assign itself to perform the role expected for the particular pin it is touching at any given moment.

    Pin 1 would start off touching Contact A. As you rotate it, it would connect to A and B. Keep rotating it, it drops A and touches B alone. Then BC. Then C. Then CD. Then D. Then DE, and so on.




  • You seal everything but the battery in one watertight compartment. The battery is a sealed, self-contained package, in a second compartment. Dunk the phone, the only thing that gets wet are the battery contacts, which are protected the same way that earbuds with magnetic chargers are protected: if the contacts get wet, the battery shuts itself off until it has been dried off.
