  • Dust from tires.

    There was an air-quality researcher who tried getting samples in Toronto, of pollen.

    He couldn’t find the pollen.

    Only tires-particles.

    The significance of the changes in tires, since the 1970’s, is astonishing.

    What tires can do, nowadays, … outright unbelievable, compared with way back when.

    Look at how far over modern bicycle-racers can lean, compared with images of the old races, when their tires hadn’t anywhere near the grip they’ve got now…

    but they’re still being poured into the atmosphere at stunning rate…

    All the wear of your tires, as the tread gets thinner, its going into the ecology, either the air or the waters or the land around the roads,

    & then you’ve got the oceans-of-used-tires which often can’t be recycled, or cost too much to be recycled…

    There has been extensive study on this stuff, btw, dig a bit & you’ll find some in-depth stuff!


  • I would suggest, instead, that “Classical Physics” is created by entanglement:

    the non-quantum reality at our scale is just what happens, when everything is entangled, to the point of clogging-up-the-works of quantumness, as it were…

    .: you get things like … as you scale up from quantum-level … the everything-is-discontinuous/everything-is-turbulence … turns into, once enough entanglement is happening, “laminar flow” in fluid-dynamics, even-though NOTHING in QM is laminar-flow, so there’s simply no basis for “laminar flow” at the lower-level…

    I wonder how significant this is, really…

  • This may all SEEM fine & dandy, but…

    The such ocean gyres, if I’m remembering what they’re called correctly, had a normal, established-for-millions-of-years kind-of-ecology in them…

    NOW, however, we’re forcing that this fungus become a dominant-player in them…

    WHAT DOES THAT FUNGUS DO TO THE OTHER ORGANISMS IN THAT ECOLOGY?


    ( people may remember some years ago when the Purple Loostrife we imported was killing all our North American marshes, turning them into thickets of woody stems/runners/etc, & each individual plant could put out 50,000 seeds per year…

    So, the Canadian Gov’t did test after test after test, & finally resolved that a … Chinese, iirc, ladybird bug ate the stuff, but didn’t eat any other plants…

    so, they imported them & let them loose…

    You know those new orange ladybird bugs?

    the ones that bite animals?

    Those are the ones, ttbomk.

    They don’t eat any other plants, other than purple loostrife, but their habit of biting us means that carnivorism is normal in them, and … how does that affect the ecology??

    You can’t just arbitrarily alter ecologies & responsibly expect them to remain functionally-balanced, & in-harmony: consequences tend to multiply each-other, & tipping-points do get crossed. )

  • I think I read somewheres that you need 240Hz monitor to reach flicker-fusion with parrots?

    It was either 120Hz or 240Hz.

    I lost flicker-fusion one time in a movie theatre when an onscreen character pulled a knife, & suddenly the screen was AVALANCHING my mind with discrete-frames, & they were jumping around ( my eyes were jumping-around, but my perspective, within my brain, had been jarred ). That even seemed to have lasted about 1 second.


    There is some video, journalism or documentary or something, on dragonflies, and the person with the knowledge was saying…

    ~ we know how long it takes for each layer in a brain ( neural-network ) to process its layer’s stuff, and we know from the short reaction-time of dragonflies that they’re using 3-neurons-deep brain for navigating/hunting/reacting.

    We don’t know how. ~


    I seem to remember that neural-signal in our biology runs at about … 300km/h?

    Something like that.


    So, with all the circuitry being shorter in an always-smaller kind of animal, it may have a predictably-shorter flicker-fusion rate?

    ( within kind, so no extrapolating from humans to birds, e.g. )


    Anyways, interesting question!

  • do you need an immune-system?

    or is AIDS fine with you?

    the answer to that question is the answer to whether your computer needs an immune-system.


    get ESET.

    Unless things have changed significantly, VirusBulletin, iirc always had them catching more of the in-the-wild viruses than any of the other ones.

    Kaspersky is Russian, so you don’t want to be trusting it.

    There are more computer-pathogens now than there were a few years ago, not less.

    Pathogens multiply, just like humans do.

  • This is right.

    Water or metal, take your pick: both massively-outperform air.

    Wikipedia often has speed-of-sound for elements, iirc…

    glancing at this, now I think that hexagonal-diamond would be most-efficient & fastest…

    https://en.m.wikipedia.org/wiki/Speeds_of_sound_of_the_elements

    Hexagonal-diamond is diamond, but with the carbon links in a different pattern.

    Apparently you make it either 1 of 2 ways:

    either alternate the orientation of layers of graphene, before compressing ( with explosives ) into diamond,

    or you put carbon into a meteor, & crash it into a planet or something.

    IOW, it forms about 60x as quick as normal-diamond, and takes insane pressure to do it.

    Normal diamond would probably be next on the scale.

  • I’ve used Linux since about 1996, when only Slackware worked for me ( Red Hat didn’t work right, & I never tried Yggdrasil ).

    Ian began his Debian distro sometime around then ( Deb was his partner, hence the distro’s name )


    About a year ago, I was using openSUSE, both Tumbeweed & their more-stable LEAP.

    They removed the drivers for my wifi adapter, in an update.

    They broke my desktop.

    Again.


    I’ve been told by Steam support ( in 2023, iirc ), directly through their system, that they ONLY support the Ubuntu family of Linuxen.


    UbuntuStudio stuck with XFCE for YEARS, even though XFCE is rigged to prevent one from being able to grab the corner of a window, because almost-all of its different options ( themes? ) permit only a 1px thick window-grabber, and that isn’t usable.

    Why??


    Try installing Haskell Stack on Void Linux for ARM.

    You can’t:

    Haskell Stack requires GMP lib, for arbitrary precision arithmetic, and you can’t get that to work on it.

    They won’t add it, to make Haskell Stack installable.

    So, if the only machine you’ve got is ARM based, and you need to learn Haskell, go get a different distro.

    ( “Haskell Programming From First Principles” requires Stack )


    I used Ubuntu Server on ARM, for awhile, and the Ruby it included was broken, with a hard-coded bit in one of its scripts that had the wrong-location for one of the basic things in Linux…

    can’t remember what it was, perhaps it was /usr/bin/mv instead of /bin/mv or something … it was stupid, though, and it was in the Ubuntu version of Ruby, which was a deprecated version of Ruby … so…

    the upstream Ruby maintainers wouldn’t fix it, because they only maintain the maintained versions of Ruby, AND…

    Ubuntu wouldn’t fix it, because they insisted it was upstream’s problem, even-though they wouldn’t include a maintained version of Ruby.

    Fuck idiocy.


    On & on & on.

    Fix 1 thing, & break 3 more , seems to be the “religion” of the various Linuxen.

    I’m old, & tired of being beaten-on by “friends” and “allies”.

    Abusers are abusers.


    IF I ever succeed in fixing my health, breaking ( permanently ) my health-obstacles,

    THEN I want to do a linux-distro that simply excludes all bullshit, & enforces correctness-of-function.

    Funtoo seems to be part of The Right Answer ( it is the evolution of Gentoo ), in that people get the benefit of whatever hardware they’ve got, instead of a dumbed-down version which is more sluggish than need-be.

    I’d want it to be based entirely on Haskell, & Julia, leaving-out pretty-much all other languages ( Haskell’s correctness & Julia’s ruthless-efficiency ).


    Notice how there is a huge push to replace X.org with Wayland?

    Wayland removes ability to run The Linux Terminal Server Project, so you can’t have little arm-terminals stuck on the backs of displays, and 1 single real-computer in the back, with an ocean of RAM, for all the students to use for their real apps…

    This “improvement” forces all to either have a powerful-enough desktop or … not be allowed to run the modern distros/Linuxen at all.

    War against inclusion of people in poorer places, where it is much more doable to afford a bunch of RasPi-terminals than it is to afford dozens & dozens of x86-64 machines, is warring for … fashion & class-status??

    The X Window System works. Through it, TLSP works.

    It enables people to have their Blender-renderer machine in the other room, where its fans-noise isn’t going to bother them.

    Fashion-motivated or fad-motivated “strategy” consistently solves the wrong problem.

    Same as breaking people’s wifi solves the wrong problem.

    WTF “loyalty” for a distro can ANYone have,

    … once one has been “punched-in-the-face” by them, enough times??


    I’ve read OpenBSD’s statement that “lack of a manpage IS A BUG”.

    That IS PROPER.

    They GET it.

    There are development/programming methods that hold-to the same kind of properness:

    Behaviour-Driven Design, e.g.

    Test-1st.

    As somebody pointed-out, of all the “agile” methods, XP included engineering-processes, like test-1st whereas … the rest, like Scrum, don’t…

    That difference-in-religion, XP’s objectivity MATTERS.

    Any “improvement” which breaks the functionality-tests or behaviour-tests, and you don’t get the “improvement” in.

    Nobody has the integrity to do that, at the distro-level?

    I wouldn’t permit any desktop-environment which is hard-coded to have 1px window-grabbers to be included in a distro, hence XFCE would have to get fixed, or it would be locked-out, explicitly for that usability-defect.

    I wouldn’t permit breaking of people’s network-access to be an official update’s component.

    MAKE IT WORK RIGHT.

    That needs to be SOME distro’s spine, that is usable-by-most, and efficient, and including the capability that people actually need to get stuff done…

    I want low-vision people being able to use it.

    I want blind-readers working in it.

    I want deaf people having full function through it.

    I want quadraplegics being able to work through it.

    I want TLSP working, so a single x86-64 machine, plus a batch of displays & RasPi’s stuck on their backs, give a classroom the ability to teach calculus with Julia which is the proper way to be learning algebra or calculus ( seriously, try Julia: it’s wonderful ).

    Anyways, you’re seeing a tiny sliver of the decades-of-abuse that operating-system makers have put in us, that is in me.

    I won’t willingly run any MS software ever again, due to their religion of molestation-of-priivacy & abuses ( I was one of the ones stung by their stolen from STAC disk-compression tech, in DOS 6.20, and their Vista era sending all searched-terms from the desktop to Microsoft violated privacy-law for both health-care sytems & for police systems, but … they’re “too big” to make accountable?? etc. )

    But the Linux world seems to have one hell of a religious-problem against stable usability.

    Distro-runners need to read a book by Al Ries: “The 22 Immutable Laws of Branding”, and understand that that stability/identifiability is a REQUIREMENT for a userbase to be not-sabotaged by one’s distro.

    DON’T KEEP CHANGING THE WAY EVERYTHING WORKS, and expect your userbase to love you for it.

    KDE 3.5 had much right-idea, but nowadays … wtf??

    Too complicated to be allowed to see where one is, within the menu-system??

    That isn’t a “feature”, that is “fashionable” mental-illness.

    And I despise the Apple-style contextless GNOME way.


    /grouch

    just an opinion, of an old, useless bastard, who’s tired of being obstructed/abused by distro-decisions.
