  • There’s some very important transatlantic cables that come ashore in New Jersey; data centres built there will have excellent links to both the Eastern US and a lot of Europe, making it quite a desirable location.

    Data centres have a few constraints on their locations. Network connections, of course, and power and water for cooling. Their margins are also a bit dubious (Ed Zitron did an excellent investigation in a recent article) but they benefit from low taxes and sweetheart deals with the local municipalities. Doesn’t take much to make that deal look shaky and be rid of the DC. Well done though NJ, keep it up!





  • Takes the ‘shell model’, which is exceedingly dodgy theoretically but gives good results, and reinterprets it in terms of quantum mechanics, which are pretty solid theoretically. So just need to validate it against what we already know - sounds like they did most of their work against a single isotope of tin.

    (We don’t have a theory of quantum gravity, so even though quantum mechanics and general relativity are both well-studied and tested theories with enormous predictive power, they can’t quite be right. If this new result gives us a better understanding of the strong nuclear force, which it might, then it might also give us a better understanding of all forces. Getting some ‘island of stability’ larger isotopes might help with packing a lot of power into a small space; elerium-115 style, too.)


  • Each package has an average of 1.1 Gb of binaries? Maybe delete a few of the old versions, then. But I think the most serious ask there is the network infrastructure - lots of big downloads around the world soon add up.

    The Arch linux package is about 150 Mb; they’ve a few larger ones, but most come in at a few megabytes. (Have just checked my Pacoloco shared cache - average of 773 packages is 5.8 Mb. That serves a network server, a gaming desktop, my personal development laptop and my work development laptop, so it’s a cross section.)




  • Audio codecs like MP3 usually do a Fourier transform to move the sound into the frequency domain, discard any frequencies that you’re unlikely to notice, and encode ‘rate of change’ for the remaining ones. So the encoding problem is usually sound with fast changes in intensity or frequency, which is basically what percussion is.

    System is quite percussion heavy, so will sound bad.

    Recently moved from Spotify to Qobuz, because fuck Dan Ek, and the fact that they’ve got better bitrates across the board really makes the difference for jazz and jazzy stuff. Neglected, sounds crap on Spotify. Sounds great on Qobuz. But that’s the change from ‘bad’ to ‘quite good’ bitrates; additional bits are very much a case of diminishing returns.



  • I’d be happy if plasma looked a bit more like WinNT. Completely functional, all the information there at a glance. Nothing hidden away in hamburger menus, no guessing about what you can and can’t click on. Does what it needs to then gets out your way. The best-designed that Windows has ever been.




  • If you’ve any suggestion on how to implement that, then it’s a million-dollar idea.

    The “I’m a human” test that only takes a few seconds and then lets you do what you like for an hour was always vulnerable to ‘auth farms’. Pay some poor bastards in the third world a pittance to pass the test a thousand times an hour, let the bots run wild. And the bots have gained the ability to pass the tests themselves, at least by boiling the oceans in some datacentre while the VC money holds out.

    Finding the people running the bots, fitting them with some very heavy boots and then seeing if they can swim in the deep ocean is probably needlessly cruel, but I’d be up for tarring and feathering a few. Once the videos got out, the rest might think harder about their life choices…


  • I dunno. Oxygen Not Included looks crisp on a 4K monitor. And it makes my job easier, being able to have an absolute tonne of code on-screen and readable. I reckon I could probably use an 8K monitor for those things.

    Yeah, I generally have FSR running on any 3D game made in about the last decade - even if I can run it at 4K at a reasonable framerate, my computer fans start to sound like a hoover and the whole room starts warming up. But upscaling seems a better solution than having separate monitors for work and play.


  • Imperial came about as a system of units by measuring “everyday” things, and it remains pretty good for that. When you step outside the everyday, then it absolutely sucks - science deals with a lot of things that are too small, and engineering deals with a lot of things that are too large.

    When I used to work in the water industry, working out how much chlorine is required to dose a hundred million litres of water per day at 0.5 mg/l, and therefore when I’d have to place an order to refill our fifty tonne storage tank, is easy enough to do in my head. If we were working in imperial, I’d have converted it to metric first and then estimated it.

    On the other hand, metric calculations for pressure suck. If I weight 160 lbs and my bike tires are at 80 psi, then I have about two square inches in contact with the ground. If my car weighs 2500 lbs and its tires are at 30 psi, then each tire has about 20 square inches in contact with the ground. If I wanted scientific accuracy, then sure, I’d do it in metric, but I’d check the end result in imperial.

    There’s near enough five thousand feet in a mile - if you need more accuracy than what you can do in your head, do it in metric with a calculator.
