  • In short, Facebook are incentivised to increase conflict and hate, it improves user engagement. They have also leveraged their large user base to boost numbers in threads significantly. Threads is already a cess pip of bigotry and hate.

    Federating with them would be like connecting your house’s drinking water pipe with the sewage pipe of an industrial pig farm. It would pollute our community to the point of destruction.

    They might try and control this initially. Unfortunately, it would almost certainly be part of an embrace, extend, extinguish attempt. ( https://en.m.wikipedia.org/wiki/Embrace,_extend,_and_extinguish ). They play nice till they have control of enough communities, then they stop the controls, to increase profits.


  • One of Sir Issac Newton’s famous phrases is

    “If I have seen further it is by standing on the shoulders of Giants”

    This sounds very nobal and humbling. However, its meaning totally changes with a few facts. It was written in an open letter to Robert Hooke. Hooke was apparently quite short, and EXTREMELY sensitive about this. Newton was basically dissing Hooke. Nobody will be standing on your shoulders, shortie!








  • I’m a parent, and we made the conscious decision to become parents. That said, I can fully understand people who don’t want to have that responsibility. It can be exhausting and thankless, changing almost everything with your life, hobbies and habits.

    On the other side of the coin, the depth of love you feel as a parent is impossible to describe. With that comes a set of incredible feelings, watching your children experience, learn and grow.

    Basically, parenthood is almost completely thankless, but I wouldn’t give it up for the world.

    I have a relative who has an unfortunate condition that causes internal bleeding. They’ve had enough blood transfusions that their antibodies are completely haywire.

    Multiple times, doctors have not listened to their protests, and given them O-. They turn an impressive shade of yellow (among other, more serious, issues).

    Last I heard, there were 2 compatible donors known, 1 in a different country. Thankfully, you can store blood longer term. It’s just not cost efficient to do in bulk. They have their own little stockpile of blood at their local hospital (mostly self donated).


  • 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.


  • 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.

    Several differences.

    The kettle is a lot closer to the cup and has thermal mass. I generally pour with the water at the bottom still boiling slightly. It takes time to get the water out of a microwave and pour it into the pot/cup.

    A kettle gets the water to a boil, then stops. A microwave is likely to either overheat (and so waste energy) or under heat, and so be too cold.

    The kettle water can be used to easily warm the pot, if needed, before it fully boils.

    Kettles are a lot more consistent for water heating than microwaves. Add water, click switch, wait for boil and switch clicking off. I would give good odds I could walk into most people’s kitchens and work their kettle without instruction or significant effort.

    Kettles can’t superheat water.

    After your, rather notorious, party in Boston, I’m just glad you’ve upgraded to using hot fresh water, rather than cold salty water.

    It’s also worth noting that tea, like coffee has a WIDE range of qualities. I’ve found most/all American teas to be well below par. This is particularly prominent in earl grey. Most earl grey sold in England is, quite frankly, shit. You only really notice when you have the good stuff.

    FYI, the reason that microwaved water is an offence to tea drinkers isn’t actually the microwave part.

    The issue is that black tea should be made using water over 95°C (203F). Basically a rolling boil, straight out of the kettle. With a microwave, your water likely hits 100, then cools quite rapidly. By the time you add it to the tea, it’s getting too cold.

    The optimal temperature is different for green or white teas, but Britain mostly drinks black tea.

    On a side note, a disproportionate number of British “explorers” wrote complaints about not being able to make a good cup of tea, while climbing mountains. The power air pressure lets water boil at lower temperatures.
