    Air will rush in at the speed of sound from any leak. It'll weigh 10t per square metre. Also 700mph is basically a bullet which you happen to be in, you want it to take lots of seconds to slow down else you best hope you're lying down, 10 seconds at 3g does not sound like comfortable deceleration, let alone 3 seconds at 10g or 1 at 30. This is about 10x the energy of an F1 crash so that again sounds fun. With literally zero room for error, unlike a plane which has much room for error and failure.

    Want to see what happens when air hits something in a vacuum? https://www.youtube.com/watch?... or you know take your pick https://www.youtube.com/result...

    The air is still coming at you at 750mph and will weigh 10t per square metre. Good luck surviving.

    Um you know the speed of sound in air is 767mph not 70mph. And when the pressure difference is 1atm that'll be the rate at which air will flood in, doesn't really matter how large the breach is. I suggest you go look at some ~15psi (~1atm) overpressure situations. https://www.youtube.com/watch?... I mean a school ping pong ball canon is basically the same as this system. That doesn't seem like fun to me. Or you know what happens in explosions.

    https://en.wikipedia.org/wiki/... 10 PSI effects:
    Reinforced concrete buildings severely damaged
    Severe heart and lung damage
    Limbs can be blown off

    So you know that sounds fun.

    Also 600000m vacuum tube seems unlikely. Expansion and whatnot.

    Actually it's not just them, see https://en.wikipedia.org/wiki/...

    The view that a number of these 'mental illnesses' are actually just part of the human condition, not something that is ostensibly wrong, does have some support among some in science and medicine and that we may be medicalising relatively trivial bits of what it is to be human. I would agree there are certainly some serious conditions where therapy and drugs are necessary to manage and control. But as this is specifically about SSRIs used to treat depression it is certainly something which there is limited data showing the efficacy of treatments, often showing similar results to a placebo. That and 50+ years of anti-depressants have actually made the problem worse, vastly more people are now diagnosed with depression and long term usage of drugs is increasing, so some debate as to if they help the majority of users is certainly warranted.

    Meditation has been shown to be at least as effective that almost all anti-depressants. So why should the value of these drugs not be evaluated, especially as increased suicide ideation is a side effect of many anti-depressants.

    It is 'culture' which is at it's heart an IFF (Identify Friend/Foe) system. But rather than just being about which hand you hold the fork in it has more rules about behaviour and 'morality'. I mean look at when the Christians banned slavery or polygamy.

    I'd argue that communism is the only governmental system which fits with Christian belief. Most of the others are 'everyone is equal' too, also much about sharing the wealth (or against the concept of wealth entirely). Libertarian is basically against the who point of the Judaeo-Christian religion. But you know what's missing the point of scripture if you get to get what you want.

    I am at least consistent, atheism, I think they are all lies used to enrich a few and control the many. I'd much rather have a morality system which doesn't need to exclude people because it deems them not people.

    I believe that it was all written to control people. I do not view it as an accurate historical record, no. But still that does not change it having said history, as with all sources one has to put them in context. I mean to accept the dates you have to accept that various people were hundreds of years old, so there are issues. But the date is based on information available in the book.

    It's not even good at setting moral standards in today's world for all the teaching about everyone being equal there are still slaves and women have no power. So it's just certain men are equal to a few other men, everyone else is not even a person.

    I mean if this is the agreement that users sign up for, that the data is theirs and will not be included in a sale because it is not an asset it could possibly be useful. You'd have to have an agreement which didn't have the 'and we can change this at any point' type language. A very narrow data specific agreement would probably be best, keep the language in it short and understandable. If they do not legally own the data they cannot sell it. Also none of the no class-action or any other restriction of rights should this be broken. I don't think corporates would be able to do this.

    Ah that must be newish as they never used to have much in the way of loose produce (then almost all have gone this way too) as I'm sure wastage is higher with loose vs prepackaged. Loose veg is rarer these days, most everything is prepackaged :(

    Foil vs CPET definitely isn't the way you put it however, I cannot recycle foil (including the 'single' use cooking trays) in kerbside recycling, I can do this for the CPET trays which are the alternative. No idea why you'd line anything with foil, the enamel trays I have are easy to clean so why put things on those that you need to dispose of? Also had you thought of making your own food not buying ready meals, that's also better for you.

    No the apples (like basically every other vegetable and fruit) come on a styrofoam tray wrapped in polyethylene. M&S are basically the worst for excessive packaging so this is an absolute joke. They basically do not have loose produce, everything is prewrapped in usually at least 2 layers of plastic, not useful stuff we can get recycled at the kerbside either.

    Early model Li-ion were maybe 100 charge cycles, that has improved to multiple hundreds, Li-po were always several hundred and can now be over a thousand. Battery tech has moved on substantially in the last 20 years (not capacity unfortunately). Most phone batteries will last at least 3 years for most users (and those in the EU get a 2 year warranty). Although the re-usability of phones is massively increased with replaceable parts. I'm thankful we're moved past charge memory of NiCad and NMH which were the height of batteries in the 90s. I've seen so many fewer battery issues with laptops in the last 5 years compared with the previous 5, so the tech is not as bad as you make out. Putting that much energy into such a small space makes me want to source genuine parts more than pattern match products, but that is no guarantee cf. Samsung, at least we've moved on from the days of $100+ replacement batteries.

    Note the 'without constant hands-on'. Newer aircraft are actually good at landing and taking off (assuming favourable weather) and may be arguably safer than human controlled, although conditions are not always favourable.

  22. There really isn't a good place anywhere else https://en.wikipedia.org/wiki/...

    If you are interested in why the meridian is in London you should do some reading, but everything else would have put the date line in a stupid place, Greenland and Iceland are part of Europe and islands are usually related to the continents they are near (the Azores and Canarys). Those few people who do live close to the date line choose the side which makes most sense to them (UTC+14 anyone) based on who they deal with most often.

  23. Technically we're never on UTC we're on GMT, which are almost but not quite exactly the same thing.

    "Since 1972, UTC is calculated by subtracting the accumulated leap seconds from International Atomic Time (TAI), which is a coordinate time scale tracking notional proper time on the rotating surface of the Earth (the geoid). In order to maintain a close approximation to UT1 (equivalent to GMT)" So UTC is a track of 'total time' where as GMT is 'local time', the up to 1 second differences exist which some high precision devices may require to know about. Your watch does not. Leap seconds are to keep UTC in alignment with UT1, so 12.00 UT1 is 12.00.abcdefgh UTC (or 11.59.abcdefgh)

  24. As mentioned, this is definitely possible, just depends on if 4k is all you want. If you want pretty then 4k is probably not going to come out of a console, but they will definitely be able to render something at 4k, just not all the things you would probably get at 2k.
