  • There are 2 parts at work. The focus reflex and the blink reflex. The window between them is the dangerous part. If the pulse is fast enough ( a few ms) then the eye can’t focus, and it’s fairly safe (unless you were already focused on the emitter). If the pulse is low enough power then the blink reflex kicks in and protects your eye.

    Hitting a mosquito is a hard task, tracking one is even harder. It’s better to use an ultra short pulse, with a bit more power. You can also shift the frequency. If it’s an infrared laser then the eye won’t lock onto it, and will struggle to focus it dangerously.





  • I’d argue they didn’t, they just changed.

    There are 2 groups worth noting. Government and private.

    Government assassination is still a thing. Israel has used it aggressively over the last few decades. There are also signs that china has too. That’s just off the top of my head. It’s also worth noting that drone strikes etc can fill the same roll as an assassin.

    Private has definitely changed. I suspect the high profile assassinations have stopped. Low level ones just had to get a lot better at not looking like assassinations. The ever classic boating accident being a good example.

    The change is mostly from improvements in policing. You can no longer just move to another city to escape the law.

    It’s also worth noting that a lot of society has changed. It used to be that a country pivoted on its leader. Now, it’s a lot more reliant on formal structures. Taking out a leader doesn’t have the same, devastating effect it used to. Iran being a good example.







  • Counselling can be useful for undoing, or avoiding maladaptive behaviours (behaviours that are intended to help one problem, but cause other, often more severe problems elsewhere). It’s mostly covering the emotional results but the line is quite blurry.

    If your tinnitus is bad enough for it to be offered, your likely experiencing emotional based stress from it’s fallout. Unpicking that, can avoid developing worse behaviours e.g. using alcohol to get drunk each night, to help fall asleep.

    I would guess, with tinnitus, you would also want more specialist help. Tinnitus itself is in the brain, it’s very often caused by physical problems in the inner ear. It’s possible to reprogram the brain to ignore the rogue signals (ghost or real). That would likely fall under the CBT umbrella, if not something even more specialised.


  • A lot of the big building companies, in Europe, treat solar panels as a premium option and so charge a larger profit margin on them. Installing solar, while constructing the house is a LOT cheaper and easier than retrofitting them later.

    The panels have gotten cheap enough that it’s no longer a real cost burden, Vs the cost of the house.


  • A friend had an excellent (but evil) one.

    His son had found some more… interesting areas of the internet (aka porn). He collected a selection of his browsing history and sat him down. They then went, video by video, having an open and honest discussion about it. Dad had FAR more tolerance for mortifying embarrassment than his son did. He learnt to clear the history at least.

    The 2nd discussion, 6 months later, used the router logs instead.

    I’m not sure I would use this particular method. However, it was apparently highly effective at making his kids think things through (for better or for worse!).






  • My wedding hit full population inversion. It was quite funny watching the few neurotypicals slowly realise the whole dynamic was wrong/unusual. Most of them adapted quickly to join the rest of us weirdos. The few that didn’t were quite out of sorts.

    Oh, and my wife didn’t get diagnosed until well after I was. Nothing was wrong. She was no weirder than her friends… Half of them are now diagnosed in various ways!


  • Part of the issue is that the category of “ebike” is quite large. It really needs to be split into multiple subcategories for regulation.

    For bikes intended to mix with pedestrians, you definitely need to limit speed and weight. Europe’s 250W, 25kph rules seem reasonable for this.

    The problem most places have is the grey area between ebike and moped, particularly for cargo bikes. They are fast/heavy enough to be a risk to pedestrians, but not enough to be classed as motorbikes. They need some restrictions/licencing to keep pedestrian areas safe, but not so much that they get lumped in with cars.
