Comment Re:I run Debian and i3 / Sway (Score 2) 49

I mostly run application fullscreen and switch between them. The only exception is when I'm comparing the content of two windows (in which case I tile horizontally or vertically) and file selection (floating).

When an application uses the entire screen without the window decorations needed in a regular window manager, a screen's limited real estate is in fact better used in a tiled window manager.

on all my machines. Once you get past the tiled window manager paradigm - if you've never used one before - you realize how fast and seamless it is, and it truly is the least common denominator in terms of memory usage.

I left Mint (which is really a Ubuntu derivative) years ago, and now i3 / Sway let I have the same unified desktop on all my machines, fast or slow, new or old, and they all feel perfectly usable.

I highly recommend spending the time to create a i3 or Sway config file. It's well worth the effort and it's a one-off.

And if you just want to try i3 or Sway on your existing distro, install it and simply change the Window manager for your user in the display manager: it lives totally independently of whatever your currently use, so it's risk-free.

Can confirm Bazzite. 85/90% there I'd say, which means there's still a bit of "tread carefully" for people. I'm very happy with the running, but I'd be less than truthful if I said it was completely frictionless.

For example, 90% of my gaming is on Elder Scrolls Online, the 'play' button on Steam runs the Zenimax launcher not the game itself and there's also an annoying recent'ish (few months) bug where it seems games launched from a 3rd party launcher don't know they've got the foreground focus. Steam thinks the launcher has the foreground., andn ESO this manifests as not autoswitching to the main game window after you've gone through the Zenimax launcher, no sound and sometimes stuttering frames because the ESO game window still thinks its in the background somehow. Random'ish alt-tabbing and clicking will bring it back, but it means there's a a) a small bit of friction where there was previously none and b) some change or regression because all this used to run fine without that issue.

I played Rez:Infinite. Great game, but it has an "Attack" mode which will crash after the third level or so. Again, friction.

I play Skyrim. Setting both Skyrim and ESO up for modding, including running some Windows binaries required by the mods, was a relatively painful learning experience.

I have a friend who wanted to switch but didn't because of kernel DRM in some of the Windows games. Once again, friction.

I'm very happy with the switch and wouldn't go back, but I'm experienced with Linux (Slackware 0.9 alpha being my first distro, and I'd installed before distros like that existed as well - anyone for Minix on an Atari ST?). I can see people not quite as annoyed with Windows as me not really seeing the benefit. For me, it was one giant Co-pilot advert too far that made me say "right then, done". After I'd told it no god knows how many flaming times, Windows popped up some "Let's get ready in your new Co-Pilot account!" thing that literally just had me hard power off and wipe the OS away. My PC is purely for gaming, I use a Mac laptop for my desktop work, so I get that luxury.

(as an aside, I do wish Steam would ban using launchers when it itself is the launcher. There's no reason for that Zenimax launcher to exist in the Steam version of the game, and it's annoying as hell because it prevents me from using Big Picture mode and just treating the whole thing like a console. That's true for either Windows or Linux, this is a 3rd party launcher thing and not an OS thing).

You're confusing the importance of avoiding Kessler syndrome in LEO with the difficulty of causing Kessler syndrome. GEO debris can potentially remain there for millions of years before interactions between the gravitational pull of the Sun, Earth, and Moon sufficiently perturb it. LEO debris remains for weeks to months. You have to have many orders of magnitude more debris in LEO to trigger Kessler Syndrome, where the rate of collisions exceeds the rate of debris loss.

The fact that a LEO Kessler Syndrome would also be short is something that exists on top of that.

It's also worth nothing that not only are modern satellites not only vastly better at properly disposing of themselves than they were in the 1970s when Kessler Syndrome was proposed, but they're also vastly better at avoiding debris strikes. All of these factors are multiplicative together.

People forget that the primary concerns about Kessler Syndrome were about geosynchronous orbit, which used to be where all the most important satellites went (many of course still go there, but not the megaconstellations). It takes a long, long time for debris to leave GEO. But LEO is a very different beast.

Yeah. In particular:

with fragments likely to fall to Earth over the next few weeks

LEO FTW. Kessler Syndrome is primarily a risk if you put too much stuff with too poor of an end-of-life disposal rate in GEO. End-of-life without proper disposal rates have declined exponentially since Kessler Syndrome was first proposed (manufacturers both understand the importance more, and do a better job, of decreasing the rate of failures before deorbit - in the past, sometimes there wasn't even attempts to dispose of a craft at end-of-life). And now we're increasingly putting stuff in LEO, where debris falls out of orbit relatively quickly. It's not impossible in LEO, esp. with higher LEO orbits - but it's much more difficult.

Or to put it another way: fragments can't build up to hit other things if they're gone after just a couple weeks.

And this trend is likely to continue - a lower percentage of premature failures, and decreasing altitudes / reentry times. Concerning ever-decreasing altitudes, we've already been doing this via use of ion engines to provide more reboost (with mission lifespans designed for only several years before running out of propellant, instead of decades like the giant GEO ones), but there's an increasing interest in "sky skimming" satellites that function in a way somewhat reminiscent of a ramjet - instead of krypton or xenon as the propellant for an ion engine, the sparse atmospheric air itself is the propellant, so the craft can in effect fly indefinitely until it fails, wherein it quite rapidly enters the denser atmosphere and burns up.

Relativity = gravity is represented by the curvature of spacetime. Curvature is linear, R. The formula treats curvature linearly. As things get closer and curvature spikes, the math just scales at a 1:1 rate

Quadratic gravity = Squares the curvature. Doesn't really change things much when everything is far apart, but heavily changes things when everything is close together.

Pros: prevents infinities and other problems when trying to reconcile quantum theory with relativity ("makes the theory renormalizable"). E.g. you don't want to calculate "if I add up the probabilities of all of these possible routes to some specific event, what are the odds that it happens?" -> "Infinity percent odds". That's... a problem. Renormalization is a trick for electromagnetism that prevents this by letting the infinities cancel out. But it doesn't work with linear curvature - gravitons carry energy, which creates gravity, which carries more energy... it explodes, and renormalization attempts just create new infinities. But it does work with quadratic curvature - it weakens high-energy interactions and allows for convergence.

Cons: Creates "ghosts" (particles with negative energies or negative probabilities, which create their own problems). There's various proposed solutions, but none that's really a "eureka!" moment. Generally along the lines of "they exist but are purely virtual and don't interact", "they exist but they're so massive that they decay before they can interact with the universe", "they don't exist, we're just using the math out of bounds and need a different representation of the same", "If we don't stop at R^2 but also add in R^3, R^4, ... on to infinity, then they go away". Etc.

The theory isn't new, BTW. The idea is from 1918 (just a few years after Einstein's theory of General Relativity was published), and the work that led to the "Pros" above is from 1977.

Mostly agree. I abandoned the Mac around Systen 7.5 era for the 486DX 66Mhz. The multitasking and protected memory spaces put it in advance of the Mac, and the CPUs started to lag the competition as well.

I came back in the OS X era (can't remember if I ever had Cheetah, but I definitely had Jaguar) where although the chips were a bit slower overall it didn't matter much because the OS was just better. Now the chips are better, the OS is better (for versions of 'better' that don't include gaming)...but the OS as compared to its own standards is worse than it used to be. Better than Win 11 - hmm. Not the highest bar anymore.

A bit more about the latter. Beyond organophosphates, the main other alternative is pyrethroids. These are highly toxic to aquatic life, and they're contact poisons to pollinators just landing on the surface (some anti-insect clothing is soaked in pyrethrin for its effect). Also, neonicotinoids are often applied as seed coatings (which are taken up and spread through the plant), which primarily just affect the plant itself. Alternatives are commonly foliar sprays. This means drift to non-target impacts as well, such as in your shelterbelts, private gardens, neighbors' homes, etc. You also have to use far higher total pesticide quantities with foliar sprays instead of systematics, which not only drift, but also wash off, etc. Neonicotinoids can impact floral visitors, with adverse sublethal impacts but e.g. large pyrethroid sprayings can cause massive immediate fatal knockdown events of whole populations of pollinators.

Regrettable substitution is a real thing. We need to factor it in better. And that applies to nanoplastics as well.

Comment Re:Soaring RAM prices (Score 1) 118

Which, to be honest, fundamentally misunderstands used RAM readings. Vast majority of that 'used' RAM is in easily discardable caches - Apple had the same PR problem with misleading reports when they released whatever the version was about 4-5 years ago and their tools reported full memory.

Windows does use more RAM than most, but it showing almost all the RAM full is the same kind of caching strategy that macOS uses. Apple eventually started calling this "Memory Pressure" and gave it a simple traffic light system. RAM is doing you no good if it's free, might as well use it to cache if there's not a hard requirement for it right that moment.
