  • Room is too well insulated and sealed. Once the bedroom door is closed, the air exchange is too low. I’m planning to fit a heat exchanging fan system next year to permanently fix it.

    Opening a window isn’t as bad as it first seems. Most of the heat in a home (at least a brick one) is in the structure. Change the air, close the window, and it will rapidly warm up again. It’s only leaving it open for longer periods that cool it down.


  • If you’ve not got one, I would highly recommend getting an air quality meter.

    I had this issue last night, awake randomly at 2-3am. When I checked, the air quality was terrible. (It’s bespoke scale put it at 10 out of 100) after opening a window and letting it improve, I happily drifted back off.

    It turned out I didn’t wake up randomly, I was dragged awake from a light sleep due to the air quality plummeting. It won’t apply to everyone, but it’s worth checking if it’s a common problem.

    (For reference, 10% air was CO2 of 2360ppm, and VOCs at 5000ppm with 80% humidity. Fresh air is CO2<500, VOCs<100)

    LLMs can’t become AGIs. They have no ability to actually reason. What they can do is use predigested reasoning to fake it. It’s particularly obvious with certain classes of proble., when they fall down. I think the fact it fakes so well tells us more about human intelligence than AI.

    That being said, LLMs will likely be a critical part of a future AGI. Right now, they are a lobotomised speech centre. Different groups are already starting to tie them to other forms of AI. If we can crack building a reasoning engine, then a full AGI is possible. An LLM might even form its internal communication method, akin to our internal monologue.

    The difference is about 0.5%. A mass weighing 100kg at the north pole would only weigh 99.5kg at the equator. Most of the difference is the centerfugal force of the earth’s rotation.

    I’ve not checked the numbers, but apparently it’s detectable in Olympic sports. More height records get broken at equatorial latitudes that higher ones.

    Some slight ramdom paper reading, back in my uni days. Though I’ve ran across it via other sources over the years since. Unfortunately I don’t have any links to hand though.

    It might better be described as people put numbers into categories. Most people have a 10-20 category. 19.99 fits. 20.00 gets bumped up to the next box. It’s a sub/semi conscious thing. If we use our higher thought process, we can deal with the numbers. That takes effort however, by default, we chunk. The price just abuses a common rollover point most people share.

    It’s a subconscious thing. It’s how our brain is wired. It’s a bit like advertising. Most people don’t like ads. However, when confronted my 2 similar products, we will go with the familiar one. The source of that familiarity is irrelevant, ads make it familiar, just the same as using it, or a recommendation.

    It’s possible to override both of these effects, but that requires a level of conscious effort. I can almost guarantee you’ve been caught by both at different times. You just didn’t notice (since noticing would allow you to correct).

    Basically, $19.99 is in the category “under $20”. $20.00 is in “over $20”. Without conscious correction, you act on this.


  • It was originally to force the cashier to open the till.

    Say an item was $20. If the customer paid with a $20 note, then the cashier could, intheory, pocket it, without it showing up on the rocords. If it was $19.99 they needed to open the till to get a cent out. This meant it was recorded, and so the till wouldn’t balance.

    Most people round down. Their brain locks on to the 1 of 19.99, and approximates it to 10.00. We need to actively counter this to see it as 20.00. It’s a skill most people don’t apply all the time, and a number can’t even do.

    Once you can do it reliably, it’s mind-boggling that others can’t, but it’s still a learnt skill, that needs to be applied.


  • My minion is still too young for that. I plan to wind them up mercilessly however. Right now, dad jokes are the height of humour to them.

    • “I’m hungry”
    • “Hi hungry, I’m dad!”
    • “Nooooooo, I’m not called hungry!”
    • “So why did you tell me your name was hungry?”

    I’ll be a little sad when it finally gets old.

    I know a few teachers, the “cringy and bad” is the goal, not a mistake. It’s apparently quite therapeutic watching the “cool kids” squirm. How bad can you make them, but not make it obvious what you’re doing?

    The fact that it also helps a lot of kids remember it is almost just a bonus.





  • My head canon, at least with Superman, is his powers. He doesn’t have multiple unrelated powers, but only 1 main one. Instinctive momentum control.

    • Flying - Momentum control

    • Bullet proof - Momentum stopped at the point of contact.

    • Heat beams - Changing the momentum of particles he’s focused on.

    • Holding a plane by a thin aluminium sheet - Adjusting the momentum of the plane directly.

    • No sonic booms, for massive wind - momentum nulling on the nearby air.

    In this case, catching a falling person safely makes complete sense. He just nullifies their momentum before they hit.

    I was rear ended, HARD once. That distance gave me the space to control both my vehicle, and the one that hit me. It turned a potential multi car, multi lane pileup into a 2 vehicle wreck, either 1 more dinged car.

    The space isn’t for the 99.999% of the time, but that 0.001% OH FUCK time.


  • We have “family film nights”. We all have dinner together, then get out some beanbags, on the floor. We then all watch a film together, cuddled up on the beanbags.

    The films are ones our daughter hasn’t seen, and can often push her boundaries. E.g. we watched “Monsters Inc” together. She was a little bit scared, but with mummy and daddy there, she loved it.

    It’s definitely one for building memories together. We are too often distracted, even when present. Having dedicated family time makes a huge difference.

    Oh, and she also doesn’t watch much paw patrol, even when around friends. Apparently “Daddy doesn’t like it” is quite enough to put her off it. A classic “respect over fear” situational win for me.

    On a side note. The screen time correlation goes away, when you correct for the child’s parenting and lifestyle situation. It’s not “screens are bad” but that kids in worse situations watch more TV, etc. The causation is backwards.
