  • I’m assuming you’re in the UK, where they have consumer units, which we call “breaker boxes” or “main panels” in the USA.

    Then the electrician fitting the new consumer unit… found that the entire ground for the whole of the houses electrics… had been disconnected at some point in the past.

    This is one thing I wish we would improve in USA electrical work, which is to test the whole installation even if only one part of the house wiring has been worked on. In the USA, the typical workflow for a new sub panel would be for the electrician to pull a permit, do initial “rough in” work, have the municipal inspector come review, do the full work, and then inspector would come to review and sign-off the final work.

    But as far as I’m aware, there’s no requirement to assess the minimum safety of the entire house, in case there were gremlins in the existing wiring, of the type that would be illegal no matter the time they were installed. No tests for ground/earth resistance. No tests for swapped line/neutral. Quite frankly, no electrical tests at all, and everything is more about inspecting the physical wiring.

    That said, inspector will check that all bedrooms have smoke alarms. So at least there’s that…




  • I can accept the premise that LLMs are being used to write Commons speeches – MPs are also people, I’m told – but these graphs suggest that LLMs are overusing certain stock phrases which have existed in the business world and apparently in Commons speeches since at least 2007.

    What puzzles me is why LLMs are more prone to using these particular phrases. Does this happen for all users of LLMs, or only when British MPs in particular are requesting a speech?

    I’d be interested to know if the same trend for the same phrases can be found in the Canadian House of Commons, since although they also follow much of the same procedures, North American English should skew the frequencies of certain words. So if the same trend can be found, then that suggests that the common LLMs do lean towards certain phrases. But if the trend is not statistically significant in Canada, then perhaps British MPs issue different prompts than their Canadian counterparts.

    What I’m saying is that I rise today to highlight additional avenues of intrigue, as MPs and citizens alike are navigating a world where AI supposedly streamlines daily activities. That certain trends may or may not exist underscores the gravity of this seemingly bustling industry that we call AI.

    [just to be clear, that last paragraph is entirely in jest]





  • I’m informed the British do read the time 6:30 as “half six”, a shortened form of “half past six”. So “inch an a half” might become “incuax”, pronounced as “in-cha” and containing the unnecessary U, and an X for that Norman/French faux lineage.

    Naturally, Americans would instead pronounce it as “in-coh”, which would destroy any understanding when also speaking about Incoterms.


  • Oh, also: 1 1/2 inches is 1/8th of a foot. 3/4" is 1/16th of a foot.

    It’s not often that I’m surprised by some of the divisors that appear in US Customary or Imperial units, but I’m now shuddering to imagine what sort of horrific system of unit names have been built atop this fact of twos-powers fractions of a foot.

    Knowing the English, they’ll likely have invented a name during the medieval time for 1/8th of a foot (1.5 inches), like dozebarleycorn, since a barleycorn is already 1/3 of an inch. And then 3/4" might be a demidoze, or some such insanity. The horror, the horror.


  • Although I suspect this particular quirk of dimensional lumber stems from the British, the result is not too unexpected for modern-day America. After all, we (insanely) deal with sales tax the same way, where the advertised price is pre-tax, and consumers have to do math if they want to compute the final bill before reaching the checkstand.

    So having to measure the lumber to acquire its actual dimensions is entire above-board [pun intended] for anything beyond putting together a wood-frame structure.




  • If only one side of the switch/points remain, depending on the type of crossing and condition of the wheels, there’s a chance that the trolley’s right side wheels can jump over the switch and continue straight forward, even as the switch is set to diverge onto the non-existent siding.

    Or it could derail but continue barreling forward anyway. But trolleys don’t tend to be going that fast.





  • Let me make sure I understand everything correctly. You have an OpenWRT router which terminates a Wireguard tunnel, which your phone will connect to from somewhere on the Internet. When the Wireguard tunnel lands within the router in the new subnet 192.168.2 0/24, you have iptable rules that will:

    • Reject all packets on the INPUT chain (from subnet to OpenWRT)
    • Reject all packets on the OUTPUT chain (from OpenWRT to subnet)
    • Route packets from phone to service on TCP port 8080, on the FORWARD chain
    • Allow established connections, on the FORWARD chain
    • Reject all other packets on the FORWARD chain

    So far, this seems alright. But where does the service run? Is it on your LAN subnet or the isolated 192.168.2.0/24 subnet? The diagram you included suggests that the service runs on an existing machine on your LAN, so that would imply that the router must also do address translation from the isolated subnet to your LAN subnet.

    That’s doable, but ideally the service would be homed onto the isolated subnet. But perhaps I misunderstood part of the configuration.



  • It took me a few reads to internalize everything that you wrote, and it’s food-for-thought for when I level-up to adding another machine to my garage. It does seem that I can wait on the jointer for a long while, and on the thickness planer until my projects start using wider boards or I get really tired of hand planing those.

    Good to know that the combo planer/jointer is not exactly optimal, and I’ll have to keep an eye out for either separate machine that happens to be for sale on the used market.

    I have no other tool that could take a quarter inch off the thickness of a 10 inch wide board; the only tool I have that is appropriate for this task is my thickness planer.

    As it happens, this was precisely what I also had to do for an earlier project, and I ended up using my router table to do it. It was an awful slog of a time, and I hope to never repeat that ever again. Throughout the ordeal, I kept thinking about how a CNC mill would have made quick work of it, but I suspect a used thickness planer is going to be a lot more affordable for me
