    It's a feature of X (so works in any app running in X, not just FF and your terminal emulator). Wayland changed clipboard behaviour (along with many other things) and decided the s…

    You could use LVM or btrfs snapshots (at the filesystem level) if you're ok restarting your database between runs

    US treasuries (bonds, notes and bills) are mostly considered as good as cash. They're used heavily in the international banking system (for payments, and as loan collateral themsel…

    This is cool! The simulator was useful for understanding what was going on, I hadn't realised until I watched a few that the roons can push marbles out in between squares.

    I don't see planning mentioned much in the article or comments. The Town and Country Planning act is a large cause of high development costs in the UK. Roads, rail, public works, n…

    This feels similar to heat pumps being >100% efficient though? Perhaps a less misleading headline would be 'Very low-power LEDs also convert heat to light'

    Ukraine's drones are already partly automated because of the jamming environment: they can visually lock the drone onto a target from up to 10km away.[0][1] They're also using dron…

    Well, the chargers won't be pulling 1MW continuously, so you can smooth this out by installing batteries with the chargers. The grid demand becomes a more constant trickle into the…

    This was a compelling idea, so I looked it up. Unfortunately it doesn't appear to be true: https://www.tesco.com/groceries/en-GB/products/253034146

    I've used my Kinesis Advantage 2 for years and am inseparable. I'd like to swap to the Kinesis 360 but my current keyboard is just fine and it feels like a small upgrade

    What's your problem with UEFI? If your OEM wanted to install malicious firmware they can do that in BIOS no?

    Systemd timer units are usually two: one for the service you want to run, one for the timer file. I think you're confusing systemd timer units with Cronie[0], a crond implementatio…

    If you're already using systemd, you can use its built-in credentials manager[0] which uses a combination of an on-disk key and the TPM2 to encrypt secrets at rest. Probably annoyi…

    I just don't think agile is designed for fixed-anything. Every project has unknowns: you can either spend effort to de-risk the project and increase your confidence in the time/cos…

    Work make me use Chrome, and I have recently converted hard to tab groups. I've found two main uses: one for a collection of reference tabs that I mostly want open or closed togeth…

    I'm not a biologist, but I'm guessing that having the concentrations of two antibiotics peak at the same time etc is much much trickier than having one molecule with two mechanisms…

    I think it's not correct to say that void is a monotype in C++, because the compiler won't allow you to assign the result of a function marked void to a variable, and you cannot de…

    Void is different from this type though, as a variable of type void can't be occupied. In ML and friends monostate is called unit (and gets used a lot because void returns aren't a…

    I strongly suspect the chances of Orion-style propulsion happening are close to zero. I think we're much more likely to see fission engines (where the heat from a conventional fiss…

    The strength of the body of the rocket comes from some level of pressurisation – much like a drinks can. I suspect that if the tank got holed the ship wouldn't have held up during …

    This is such a good book, and it was very accessible as someone with little chemistry education.

    Is that explained by capacitance? I'm sure the capacitance of your finger through paint is pretty low but capacitors allow AC to pass
