  • Yes, I absolutely have understood that. I also understand that that means the assumptions that a ring main are built on - that the distribution of load around the ring will be even in relation to the supply point - no longer apply.

    In a ringmain, any individual stretch of the inwall wiring is under-rated. A single two-gang wall socket (with 2 perfectly legal and standard compliant 13A fused appliances/multisockets plugged in) can draw more current then the cable in the wall is rated for. It is “safe” because it relies on the current being drawn, on average, equally from both sides of the ring. If you plug a generator in that is closer to the socket, that is no longer true - more current will be drawn on the shorter path to the generator than the longer path back to the fuse box. An already marginal system is now unsafe.

    I’m not saying it can’t be done, and I hope it will be done, but it works in Gemany is a fucking stupid comment that we keep seeing but is irrelevant because Germany (and almost everywhere else on Earth) has a completely different domestic electrical system.




  • “That system” was not “designed for electric heaters” (I have no idea where this ridiculous myth comes from, ) it was designed to cut costs because copper was expensive after the war.

    In-plug fuses do not make it safe, they help mitigate two critical flaws: the first, that a faulty appliance can draw 32A through a 13A cable without blowing the distribution fuse, and secondly (relevant to this case) they make it harder - but not impossible - to unbalance the ring by plugging too much load into a single socket.

    But it’s only a mitigation, it doesn’t make it safe. A standard two-gang wall plate on its own is all that is required to overload the inwall wiring (26A from two sockets on a 24A feed protected by a 32A breaker.) Adding 4A of feed-in as well is a significant bump to the risk of an already unsafe system.

    And sure, nobody is going to notice the problem on day 1, and as long as the only electrical appliances you use are mobile phone chargers there is never going to be a problem. But a while down the line when the householder decides to plug in a couple of the new AC units they feel they can now justify because they’re powering them off solar, whose maximum draw just happens to coincide with maximum solar production, that’s when the smoke will come…

    (And that’s ignoring the ubiquitous DIY’d spur off the ring for the conservatory or extension, or the accidentally broken ring when someone replaced a wallbox and now they actually have two 24A radials on a 32A fuse - all far from uncommon in any UK house that ever had a home improvement nut living in it.)



  • Everyone doing the “it works in Germany” dance needs to remember that the UK, almost uniquely, has ring main domestic wiring, which presents unique safety challenges.

    (Specifically, in-wall wiring that is under-rated compared to the fuse that protects it (e.g. 24A wall wiring on a 32A fuse), which is only safe if the ring is in-tact (no undetected breaks) and, critically for this application, the load is evenly distributed around the ring.)

    Yes, it can and should be made to work - but it is not as straightforward as “herp derp works in Germany so yolo”.


  • It’s only regressive when framed as a tax on consumers - which is of course easier to do in a ridiculous country that allows retailers to advertise prices without all the retailer’s costs included.

    A properly organised VAT type tax is not regressive - it’s a tax on corporations that buy product for cents and then sell them on for dollars, pocketing the difference. I’ve no idea why sales taxes bring out this “but won’t somebody think of the corporations!” handwringing.



  • Yep, I set mine up last weekend.

    Used a nice Racknex rackmount kit to put a Raspberry Pi with SDR in the rack, and a little LCD display on the front that cycles through the details of aircraft currently in range - so it also serves the important purpose of Blinkenlights.

    I’m fortunate to live close to two international airports (one small, one big) and under a reasonably busy flight corridor as well, so plenty of planes to spot - light aircraft, helicopters and military all the way up to A380s.


  • Quite; I just set a (locally hosted) LLM off writing the tickets for implementing all the opcodes in a simple device emulator, based on grovelling through datasheets and documentation. Whether the tickets get implemented by an AI or a human, it’s a timesaver having the AI do it, and the tickets will be better written than I would have done.

    Everyone railing against this also overlooks the reality of professional software development: professional software is developed 5% by skilled, trained Software Engineers, and 95% by code monkeys who shotgun copypasta from Stack Overflow until it works. Even if we extremely generously assume that the hardcore “never use AI” Lemmy brigade are in the 5% (and not, more likely the 95% drowning in their own Dunning Kruger,) the “but AIs produce unreadable code and make mistakes” threat isn’t putting off anyone who’s ever actually had to hire a significantly sized development team.



  • You can subnet logically with IPv4.

    If you go IPv6 on the internal network you ‘win’ not having NAT, and exposing all your intrrnal services to the net (which… just why?), but lose the ability to do redundant ISPs/failover/loadbalancing, policy based routing, VPNs… Unless you do IPv6 address translation. Which puts you back to “IPv4+NAT, except more complicated.”

    IPv6 inside the firewall is more or less entirely pointless.


  • I wouldn’t have an objection to paying them for that.

    I did object them to them trying to charge me to stream from my server to my TV in the same house without touching any of Plex’s infrastructure at all, because their license-check is too dumb to understand some of us use things like “subnets”. (I objected even more that their “support” teams are evidently staffed by obnoxious jerks trained only to say “give us money”.)

    Fortunately I found the switch to Jellyfin incredibly easy, and so far it’s actually been more reliable than Plex ever was.

    I was contributing to Open Source almost certainly before you were born, so wind your neck in kid. But, even if we suppose you are right and the GPL somehow restricts the use of licensed works for AI training (although a quick refresh on the license shows no evidence that it does) - while GPL fanatics make the most noise, it is absolutely not the most popular open source license.

    GPL variants covers roughly 20% of the licensed work on Github. The vast majority of such work is permissive open-source licensed, with the MIT license covering almost 50% alone. That’s because the vast majority of open source contributors are not in fact wannabe Citizen Smiths, but rather people who want, without restriction, to contribute to the advancement of computing.
