  • My dad picks up hobbies like other people pick up interesting stones at the beach. He got into home networking a few months ago and has since spun up an onion architecture of networks from least to most trusted. All IOT devices get segregated on their own individual networks and the secure core network has adblocking and tracking-blocking firewalls. He has like 3 guest wifi networks. All addressing is resolved with IPv6.

    His home, by the way, has one home computer, three phones, and two smart speakers. Twenty year old dumb TV. No smart appliances.








  • I’d just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.

    Firstly, a black hole isn’t an object, really. If you manage to compress enough mass in one place, gravity becomes the dominant force and the mass collapses into itself, eternally compressing and densifying. This is the singularity at the center of a black hole, and we use the term singularity because it’s describing a single unmeasurable point in spacetime.

    Next point: high gravity curves space. Light only travels in straight lines if it can get away with it, so when light bends in space it’s because the space being traversed is deformed by gravity. Like, the Earth is, as far as it cares, going in a straight line that happens to curve back to where it started. If gravity is strong enough in a region, all possible “paths” through space become bent inwards to higher gravity. Like, even a perfectly straight line away from the black hole will be forced inwards again. That’s the event horizon, the region in space around the singularity where nothing can escape anymore: all paths go deeper into the black hole.

    Third point: weird shit happens inside the event horizon. We’re well into Math now because we can’t actually see inside these things, but we can use math to theorize and describe the inside of a black hole. Basically, time and space switch places inside the event horizon. Because every possible direction you can move in only takes you deeper, that means the future is the singularity, and as you move forward in time you move closer in space to it.

    So in net: they’re not really holes and they’re not really physical objects: they’re regions where every path in space is forced into going towards the singularity, which is itself infinitely small and infinitely dense.

    Anyways, you can accurately calculate the precise size of the region. It’s called the Schwarzschild Radius, and it’s the size of the black hole that any particular amount of mass, if forced to collapse, would become. Turns out that if you calculate the size of the black hole that contains all of the mass and energy in the universe, it would be about the size of the universe, but not quite precisely. That’s all that’s been calculated.


  • The only places it seemed to work were those that were already established as the centers of capital and were thus benefiting from the expanding frontier of exploitation. Capitalism has run out of land and run out of people outside the imperial core to further exploit and so turns inwards to devour its once-beneficiaries. Internationally and especially in the global south it has served no purpose, ever, except to brutally oppress and exploit.
