  • The moon is receding from the Earth and would eventually roughly double its orbital period, while Earth’s rotation would nearly stop (one rotation every 47 days), and both would be tidally locked to the other. The same side of the Earth would always face the moon, and the same side of the moon would always face the Earth (as happens currently).

    This is all assuming the system would continue unperturbed forever, however, it won’t. Before the above happens, the sun will turn into a red giant and the drag from the expanded atmosphere will slow down the orbits of both the Earth and Moon, eventually leading to them both ceasing to exist - the moon from reaching the Roche limit above the Earth, and the the Earth from entering the Sun’s photosphere and eventually spiraling into the core.





  • As someone with an Nvidia GPU on Wayland, unfortunately quite a few places.

    Resuming from sleep requires power cycling the monitors.

    Glitchy transparent artifacting down to the desktop if windows are overlapping next the task bar.

    Widgets in the system tray (KDE Plasma - I have temperature readouts) disappear and reappear randomly, and sometimes switch which taskbar they live on.

    VRR support is pretty bad, causing black screens when using full screen applications.

    2D-heavy games are flooded with thousands of vulkan draw calls, leading to abysmal performance and massive current spikes (and therefore coil whine). This is mitigated per-game with dxvk settings - often removing the whine without improving performance.

    HDR is … technically available.

    Overall I’m happy, but I cannot recommend this experience to anyone I know because it would drive them insane.




  • To put some math around CO2 usage:

    The entire structure of plants is built primarily from CO2. A tomato plant and fruit grows from seeding to maturity in about 60 days, and will yield about a kilogram of dry plant mass.

    That mass will be about 20% carbon, meaning each plant would need to uptake a net 3.3 grams of carbon - 12.3 grams of CO2 per day. A person exhales around 1Kg of CO2 per day, or about as much as would be needed to supply 81 tomato plants.

    And it is a terrible thing for science and contributes greatly to the crisis of irreproducibility plaguing multiple fields.

    If 1000 researchers study the same thing, and 950 of them find insignificant results and don’t publish, and 50 of them publish their significant (95% confidence) results - we have collectively deluded ourselves into accepting spurious conclusions.

    This is a massive problem that is rarely acknowledged and even more rarely discussed.




  • The biggest factor is diet - a large portion of ingested water comes from food.

    Someone who snacks on carrots is going to need to drink a very different amount of water to stay hydrated as someone who eats jerky and crackers.

    There’s also obviously differences in kidney function, salt retention, even just body size. Current medical advice is to just drink when you are thirsty, which works for just about everyone.



  • The issue isn’t forwards, it is down.

    You have a tungsten rod held in a clamp on a satellite in a nominally stable orbit. Releasing the clamp just means the tungsten rod is now in essentially the same nominally stable orbit as the satellite.

    To deorbit it, you need to meaningfully change its velocity. As tungsten is very dense, that takes a lot of fuel. The more fuel that is used, the sooner the rod will hit the ground and the higher the angle.

    Simply dropping it means you have to wait months or years for the orbit to naturally decay, a lot of energy will be lost to atmospheric friction, and there is little control over the impact point. Not exactly what you want in your WMD.




  • Well, sort of. HDCP exists, and does make it harder to capture an AV stream.

    For interactive content, the current push online components hosted on external servers adds a lot of complexity. While a lot of that stuff can be patched around by a very dedicated community, not every piece of content gets enough community appeal to attract the wizards to do such a thing.

    And while anyone can digivolve into a wizard given enough commitment and effort, the onramp is not easy these days. Wayyy back when cracking a game meant opening the file and finding the line for 'if cd_key == ‘whru686’, it was much easier to get casually involved. Nowadays, DRM has gotten so much more sophisticated that a tech background is essentially required to start.



  • No, not even close.

    I’ve used Unix systems for years at work, and have dual-booted windows with various flavors of Linux at home for just as long. When I just need something to work, particularly something new or after a stressful day at work, I just use windows.

    Why? Because it will just work. Maybe it won’t work precisely how I want it to, maybe it will send all my data to Bill’s push notifications, but it will run. In the rare case it doesn’t, a quick google will fix it.

    Compare that to Linux, where most things will work most of the time. And when they don’t, you get to hunt through GitHub issues off-the-clock like a peasant, wading through comments from people with entirely different configurations and ‘dunno it works for me’.

    Linux is for tinkerers, and for people who want a Unix shell and can’t afford a Mac, it has a long way to go to be more than that.

    The ideal answer is compost, regenerative agriculture, and (better treated) human-sources waste.

    Organic crop yields will almost certainly reduce a bit without animal waste fertilizer, but that is fine since crop consumption will fall by a greater amount due to not needing to feed a bunch of extra animals.
