  • Well, this is how a large part of how carbon credits “work”. You can pay someone to not cut down their tree, for example, and get a certificate in return. However, the demand for wood will likely just get satisfied elsewhere and there is little stopping people from selling multiple carbon credits per tree, or just including trees that would not get cut down anyway.

    In the best case scenario, actual carbon gets stored so that it won’t decompose (like dead trees or other biomass in oxygen, maybe even plastic someday) or burned (like coal that future people can reach); however, that’s energy-intensive (hydrocarbons release energy when turned into oxides and vice versa) and difficult. Obviously, such carbon credits are expensive and they would probably cost an airline as much as fuel for your flight. Sealing an oil reservoir instead of using it, as I suggest, would be the easiest way to effectively accomplish this but oil producers don’t want to miss out on the fields they operate.
    Unless the “carbon neutral” option for your flight ticket is a large percentage of its price, they are probably using dubious carbon credits - in the typical case, they are like saying your crypto mining rig is zero-emission because it’s next to an existing hydroelectric dam. The energy from that could have been used to offset some carbon-intensive production elsewhere (unless all your energy demand is already satisfied by clean electricity and you cannot export, like Iceland some islands).
    At worst, it’s a pure scam that offsets no carbon and is pushed by Big Oil to prevent buyers from considering systemic changes to their carbon-heavy operation.

    Edit: Iceand indeed has an overproduction of clean energy and they use it to extract and export aluminum, which is energy-intensive. Still, as long as there are gas furnaces and combustion engines on the island, there is room for improvement. However, small tropical islands (which cannot host aluminum factories) mostly use solar panels and some storage solution, and computationally heavy tasks are a legitimate use for any excess electricity production.







  • Input devices almost never use USB 3.0. In fact, most manufacturers save money and don’t shield the cable, forcing half-speed USB 1.1, which is enough for all mice and keyboards - less than 50 kb/s of the available 6 Mb/s is required even for 240Hz polling. High-end mice might have USB 3.0 (9 pins instead of 4 in the plug) but there should be no practical difference between 3.0 and 2.0 speeds. The polling rate will most likely be identical and the microsecond difference between how long each takes to transfer the data is likely way lower than lag from the mouse’s wireless connection.

    Just use any USB 2.0 hub, even $2 ones from AliExpress will work the same as high-end ones. Most are sold with 4 ports because that’s what their standard generic chip does. You probably have one lying around or built into the monitor. You’re unlikely to cause interference so just choose any spot with strong signal to the desk area, not necessarily line-of-sight: if the mouse works everywhere within 2 meters from the intended area, then the intended area will have good signal and minimal chance of dropout. The lag or polling rate does not decrease with signal strength unless you count extra nanoseconds the radio waves need to travel.

    The only difference is when you need another port for high-speed applications such as mass storage devices or MTP with your phone, at which point just plug them directly into the PC for max speed.





  • They are purposefully slowing down old.reddit.com. Expect a lot of refugees when its inevitable shutdown happens.

    Anyway, infrastructure mismanagement is typical for late-stage enshittification. Value of the company goes down, and execs who have sold their shares high are quietly stealing equipment from the datacenter to get some value out of it. (Not literally, they just fire any techs who suggest overdue upgrades and give themselves a bonus for making such a difficult decision.)

    By this logic, the Earth would move at supersonic speed below me whenever I jump. When I start falling, I keep my momentum with the surface of the Earth.

    Anyway, of course there will be lateral movement because it’s hard to control one’s aerodynamics precisely enough. But theoretically, if you had an indestructible smooth pipe and there was no drag, you could safely travel to the other side of the world in under an hour.
