  • LLM usage

    The golden rule for LLM usage in KDE is Don’t be lazy:

    Don’t try to use a tool to replace your own judgment, interpersonal communication, or learning process.

    Don’t take unsustainable shortcuts.

    Don’t avoid growing as a person.

    The result will be poor-quality work that eventually becomes someone else’s problem.

    Nobody in KDE should know if you use an LLM — not because you’re concealing it, but because your usage of it produces output indistinguishable from what you could produce yourself. Contributions with obvious and lazy LLM usage may be ignored or closed.

    Are we reading that same thing? Hardly seems like a pro LLM stance or the worst take that could be made.



  • I wasn’t genuinely serious. I find the politics over what is simply projection maths rather funny, both because of the actual impact it has and the stupidity of that impact. I bet Trump truly thinks Greenland is bigger than it is.

    Counter point though. Screens TVs and phones are perfectly capable of displaying true scale globes. Google maps used to do this when you zoomed out enough. I think it still does with the right settings.

    You do need to spin the globe to see the other side of the planet though.

    It is basically only printed media that is forced into projections.



  • This is a rather common misconception about sensitivity, it is only true under the constraint where you are unable to increase the amplitude of your measurement.

    You are always limited by shot noise (counting noise, quantisation noise, Poisson noise, whatever name you give it). And people love to say that you can only beat it by squeezing (increase noise in one quadrature to reduce it in another). But another option is to just increase N, turn up the laser power to have more photons or atoms in your sensor and watch your noise floor drop way faster than you will ever get using squeezing.

    Now the cold atom sensors are an interesting case. No one has managed to laser cool atoms faster than an overall rate of around 10^9 atoms per second. And we have been stuck there since the mid 2000s. As a result, the fundamental noise limit from shot noise hampers these cold atom accelerometers significantly in short term sensitivity, as they just don’t have enough N of atoms in free fall. In this case, you might look to squeeze to get a better signal, but that’s a lot of complexity for not much gain.

    There are only 2 examples I know of where squeezing has made a difference to a real world measurement. LIGO, can’t increase photons without thermally heating the mirrors too much, and confocal microscopes looking at biological samples, cant turn up the laser power without burning the tissue. In 99% of cases, just increase N to make a better sensor.











  • Exactly, I’m not sure how people can’t fathom how expensive it used to be to run everything on cash.

    The free cash cost of the past had factored into it, the 30 minutes of wage needed to clear the tills and check the balances, the bank fee that they get to process 5kg of shrapnel, armoured guards to move large sums of cash around, specialised training, firearms and custom vehicles. Cash was an industry, of which a small amount remains.

    Now the extra cents they slap on your card payment at the tap, that has always been bulshit. The price on the sticker being the amount you pay is a core tenant of this country, and I’m glad they are cracking down on it.

    I’m also strongly in favour of keeping the cash option there. Many many good reasons to have it around.
