  • That method is still mostly recommended, though mostly for younger children/babies. The Heimlich maneuver is difficult to perform on a small body. You either over squeeze, and cause harm, or are too tentative, and so not helping.

    With babies, you hold them lying on your forearm, facing downwards, and slap (open handed) hard. I’ve only seen it used once, but it worked perfectly then.


  • The best bet is to let your local aviation authority know. They are generally the ones with the actual powers, as well as the knowledge to apply them.

    At least in the UK, the laws cover anything that leaves the ground under an open sky. There are exceptions for RC toys and drones, but they have limits. One of the limits is you cannot fly within a certain distance of anyone or anything not under your control.

    Basically, most places require your permission to fly over, or near to your land. If they are overflying, they are breaking the rules.

    It’s worth noting, depending on the size of the system, it can be difficult to judge distances. The ones I work with are large. We regularly have officials insisting we are massively out of our flight area. GPS logs show that it was well within the entire time.


  • The left is far less monolithic than the right. It was a sub-subset of the left, a percentage of feminists were/are anti male. Unfortunately, they were not called out for this, and so got very loud about it. This coloured the message from general left leaning sources.

    Growing up, there was a lot of “men are bad/evil” and that we needed to make it up to women. A lot of this pressure came from left leaning sources.

    Thankfully, I managed to avoid getting drawn into the right leaning backlash to this.



  • It did well for a long time. The BBC produces a lot of excellent programmes. It was also unafraid of holding the government’s feet to the fire.

    Unfortunately, the Tories successfully gutted it about a decade back. It still produces excellent programmes, but is neutered politically.

    As for the licence fee. It is effectively an extra tax. However, if you don’t watch TV, you don’t have to have a licence. It’s not perfect, but better than just a flat tax. It also helped keep them semi independent of the government.

    Training, lots of training. It also applies to you as well!

    I think our dog got past 2 years old before we had eaten more pork chops than he had stolen.

    He’ll still swipe my daughter’s dinner, if it’s left unattended. At least he will no longer steal it while she’s sat in front of it.


  • There’s a story, though I’m not 100% sure on how true it was. Queen victoria did a royal visit to the new lab overseen by Michael Faraday. She asked him what use this new “electricity” was? His response was along the lines of "mam, we’re not completely sure, that’s why we are researching it.

    As for actual uses. It could give us the theoretical key to room temperature super conductors. It could give us a foundation for exotic space drives. It could help crack new forms of fusion reaction.

    Ultimately, it’s a foundational block. What gets built on there is hard to predict. By comparison, GPS is not an obvious extension of relativity. However, without an understanding of relativity, GPS would basically be useless. It would drift km/day


  • The limiting factor is the bend. The subatomic particles want to go in a straight line. A magnetic field is used to bend the beam around into a circle. The faster the particles are moving however, the more energy is needed to bend them. A larger circle has less bend. This lets you get your particles faster.

    Since E^2 = M^2 C^4 + P^2 C^2 (the full form is E=MC^2 ). If you can force the particle to stop rapidly, then you can force the energy from momentum into mass. This is done by hitting 2 beams into each other. The faster the beams, the more energy is available to convert to mass.

    Most of the time, this creates a lot of mundane particles. However, ever so often it creates something interesting. They rapidly decay into mundane particles, but the shower they create tells us a lot about them. The catch is that all the energy needs to be present at once. You can’t use more particles, you need to make them move faster.

    As for why. The more particles we have to study, the more we can figure out about the underlying rules. We have a number of theories. They all agree at lower energy levels, but disagree at higher energy levels. By knowing which is correct, we can pry deeper into the workings of reality.


  • In almost all cases the point is to keep things reversible. The problem is puberty. Once the hormone cascades hit, it’s far harder to transition. At the same time, fully transitioning is not something many children are equipped to cope with.

    Luckily there is a 3rd option. Puberty can be delayed without permanent issues. This gives the patient and doctors time to figure out what to do long term. If they were confused, they stop the drugs, and puberty happens normally. If they truly want to transition, they are in a far better position to change than if they experienced puberty as the “wrong” gender.

    By delaying the changes, it allows time for them to process what they want. It also lets them experience living as the other gender, in a reversible manner.




  • Nothing is destined, the past is fixed, the present is happening, but the future is still ours to define.

    Don’t get me wrong, it fucking hard to even start clawing your way out. Even worse, you won’t see any benefits at first. Even just taking the first steps seem terrifying and hopeless.

    I’ve been in that hole, I still have that voice in the back of my head. There are 2 ways out, only 1 offers the possibility of happy moments.

    I personally decided (eventually) to say fuck it, and plough forward till I made it or it killed me. I had to go way past where I thought my limits were. But the voice was wrong, I was (and am) far more capable than it told me.

    If you want some advice on mental control techniques, I’ve a few that might help. I’d be happy to share if you want.


  • That’s your choice. Just don’t expect others to change your life for you.

    And if it helps. I went through that cycle more than a few times. Put effort in, get nothing back then give up, and slip further. Even now, it’s a constant battle. I know where I will end up if I falter however, so I keep my foundations strong, even when the depression tells me it’s not worth the effort. Those anchors make it possible to pull myself back out of that pit of despair.

    Oh, and yes the initial climb out is exhausting, rewardless and terrifying. I fully understand why you don’t want to try again. I’m just saying that the climb isn’t infinite, and there’s firm footing further up.


  • It sounds like you have depression messing with your mind. I empathize a lot, since I’ve been in that place.

    The thing I will say is that most of the problems looming over you are paper tigers. They have far less substance than your mind is telling you they have.

    Unfortunately, the lesson I learnt was that no-one will actually help you. People will make a lot of nice noises, and will even accommodate you, but they won’t help. That needs to come from you. Don’t get me wrong, it’s terrifying, but it’s like neo taking the red pill. It’s not that he’s not scared, but that he knows the other option is not where he wants to be.

    Up until now, I’ve just been making nice noises, so onwards to some practical advice.

    Appearance.

    You mentioned you are a bit of a lock in. Often you can get your appearance slip, don’t let it. It can be as simple as keeping personal hygiene sorted, and wearing “smart” clothes when you go out. They don’t need to be expensive, just look nice. For men, a button up shirt and some chinos can make a huge difference to how others react to you.

    Socialising

    As painful as it is, social skills are a necessary tool of life. They also go rusty VERY quickly. This leads to a feedback loop that leaves socialising as a terrifying idea. Your goal should be to have a short conversation with a “stranger” every day. This could be as simple as asking a cashier how their day is going, or asking for directions from someone out and about.

    At this point you’re probably mentally whimpering “I can’t do THAT!”. You actually can, and most people will actually respond positively. The part of your mind saying you can’t is the problematic part. Recognise that it is trying to help, but that its advice is bullshit.

    Anchoring

    The above is the most basic stuff you should be aiming for. The most important thing however is to establish mental anchors. Think of them like the bolts climbers use for their ropes. Reaching them is hard, but once they are embedded, recovering from a fall gets a lot easier. You also preferably want several anchors. Sometimes they fail, it happens. If you only have one, that can cause problems, but if you have several, repairing the lost one becomes a minor annoyance.

    A good anchor is a commitment you can lean on and say “that’s a positive thing for me” even when you really don’t feel it. Groups, or periodic events work best. Meet-up is a good resource for finding things and ideas. Some more ideas below.

    Gym - a regular fitness regime does wonders for your mind. It also gives organic opportunities to talk to people.

    Sports - often cheaper than the gym, find a regular sport meetup and go along. Don’t worry about being completely rubbish at the start. Most people respect effort, and you will see the payoffs quite quickly.

    Martial arts - similar to the above, but a bit more formalised.

    Dungeons and dragons - one of the classic “weirdos unite!” socialising methods. If you’re polite, and followed the hygiene advice earlier, you’ll find most groups extremely accepting.

    Makerspaces - if you’re engineering/creative then these make excellent opportunities to socialise. I actually ended up establishing one. It turned out I wasn’t the only weirdo in the area who wanted somewhere to socialise on our terms.

    The pub - a classic, but often doesn’t fit a lot of people’s mindset.

    Cinema groups - cinema has gotten a bit expensive now, but once you have a job again they can be a good social event. You get to hang out with a group for a while, without needing to talk much. Once the film is over, you have an automatic topic of conversation.

    I’ll leave things there. Just remember, that voice in your head means well, but is lying to you. The looming monsters are paper thin, but only you can punch through them.

    When one of your times is in milliseconds, while the other requires awareness of relativistic effects, you might as well call it instant.

    The propagation speed in copper is 2/3 C. With analogue monitors, that was effectively amped and thrown at the screen. The phosphate coating is the slowest part, that takes 0.25-0.5ms to respond fully.

    By comparison, at the time, “gaming” LCD screens were advertising 23ms response rates.
