  • True. Hence my caveat of “most cards”. If it’s got LEDs on the port, it’s quite likely to signal which speed it is at with those LEDs.

    I haven’t yet come across a gigabit card that won’t do 10Mbit (edit: switches are a different matter) but sometimes I’ve come across cards that fail to negotiate speeds correctly, eg trying for gigabit when they only actually have a 4 wire connection that can support 100Mbit. Forcing the card to the “correct” speed makes them work.







    1. Replace CMOS battery.
    2. Get small UPS.
    3. Discover that small UPS’s fail regularly, usually with cooked batteries.
    4. Add maintenance routine for UPS battery.
    5. Begin to wonder if this is really worth it when the rest of the house has no power during an outage.
    6. Get small generator.
    7. Discover that small generators also need maintenance and exercise.
    8. Decide to get a whole house battery backup a-la Tesla Powerwall topped off by solar and a dedicated generator.
    9. Spend 15 years paying this off while wondering if the payback was really worth it, because you can count on one hand the number of extended power outages in that time.
    10. In the end times a roving band of thugs comes around and kills you and strips your house of valuable technology, leaving your homelab setup behind and - sadly - without power. Your dream of unlimited availability has all been for nought.

    Conclusion: just replace the CMOS battery on a yearly basis during planned system downtime.


  • I had a full run of vaccinations and got COVID about 6 months later. Nothing serious, in bed for a few days, cold and flu tablets kept everything under control, a perfect case of the effectiveness of the vaccines in taking the edge off.

    But for about two weeks after “recovery” I was constantly forgetting keys, or my wallet. Drove halfway to the airport for a week away for work one morning and went, “oh shit, where’s my wallet?” and I’d placed it on a bench behind my car when I put my suitcase in the back and didn’t pick it up again. I’m 50 years old, I can count on one hand the number of times I’d forgotten my wallet before that.

    That brain fog eased off after that but I wonder sometimes if there are still long term effects that I’m not aware of.

    Splitter is fine as long as there is somewhere for the water to go after it exits the regulator. You need that flow for it to work.

    Just know that you also need a bit of back pressure so the regulator can actually reach the point of regulation, I mentioned sprinkler heads but this back pressure can be a hose with a nozzle, or just your thumb on the end even, as long as there is a bit of flow 😄


  • Hey there.

    Pressure regulators typically only work when there is flow and also back pressure they can work against.

    If you try and measure with the gauge like in the picture you will basically end up measuring input pressure as any tiny leakage of water through the regulator will have nowhere to go afterwards and pressure will build up.

    If you want to test the regulator, you need to put it in a line with a few sprinkler heads on it so that there is both flow and back pressure and then put your gauge in a tee piece on that line so it can measure the pressure of the water flowing past.




  • But, critically, it’s not a fucking CAPACITIVE BUTTON, and I’ve never accidentally hit it once.

    Yeah. I use resume a fair bit because you can set it to the speed you want and if your cruising gets interrupted by a slow truck, or roadworks, or by passing through a town, you can just press it and the car will accelerate back up to the set speed. Not like a rocket, maybe a couple of km/hr per second.

    But still, like you say, easily-triggered capacitive buttons for critical functions, holy shit that is a bad idea.



  • that works how the article describes, where it will accelerate you to whatever the last cruise control speed was.

    That’s what the resume function does normally?

    That is:

    • You switch on and activate cruise control
    • You’ve tripped it while active by pressing the brake

    At this point cruise control is still “hot” and pressing resume will turn the cruise control back on, usually with a speed interlock so you can’t activate it at a dead stop.

    If the car has “one pedal driving” then inadvertent activation could be pretty surprising, and would require you to lift your foot off the accelerator and hit the brakes. Coupled with the rocket-ship acceleration of most EVs this could easily cause an accident I guess.


  • Your rods and cones in your eye and the nerves that transmit the information to your brain have signalling limits, they can only fire so fast and they have a time to reset. It depends on lighting and what you’re focused on as well.

    Which is why film can get away with 24 frames per second because in a dark theatre and a bright screen 24 fps is enough to blur that signalling so that it looks like decent motion. Only thing cinematographers had to watch out for is large panning shots as our peripheral vision is tuned for more rapid response and we can see the juddering out of the corner of our eyes.

    I could see the 60Hz flicker of crt monitors back in the day if I had a larger monitor or was working next to someone with 60Hz. Not when I was directly looking at it, but when it was in my peripheral vision. The relatively tiny jump to 72Hz made things so much nicer for me.



  • Maybe mention the fact that this recent alarming jump is very likely due to us doing accidental geo-engineering for the last 80 years and we’ve only just stopped it.

    We finally banned sulfur-laden bunker fuel globally for shipping last year. Dirtiest fuel in the world basically, all the left over crud from refineries straight into your cargo ship’s engine. Sounds like a good environmental move but, oh shit, guess what? Those sulfur aerosols the ships were pumping into the atmosphere worldwide were actually keeping surface temperatures down.

    Climate scientists were shitting themselves over the temperature jump until someone made the connection. They’re still shitting themselves over it now, but at least it’s an explainable jump now.

    It’s proof that fairly “trivial” changes by humans can have measurable effects on climate.



  • You’re never going to live in a world where you’re allowed to fly without photo id amigo

    Move to a different country.

    Eg in Australia I can book a domestic ticket and have two interactions after that:

    • x-ray/security where they scan my carry on
    • boarding at the gate where they scan my pass.

    No photo ID - or any ID really - needed. Now there’s enough dribs and drabs of information when I book the ticket and etc etc that they can identify me, but there’s nothing stopping someone from booking a ticket for someone else under their name.
