  You actually have gotten a bad explanation. There’s no such thing as being “a little too fast” which would cause this effect, and there definitely is no “spiraling out” due to inherent speed/momentum.

  An object in orbit of another remains in orbit as long as its horizontal velocity is high enough to not be pulled into a collision with the parent, but low enough to not escape the gravitational pull altogether. The closer to the parent, the stronger gravity affects the object, so you have to go faster horizontally to keep “missing” the parent, making gravity only pull you into a circle around it instead. That’s why it’s also called orbital speed: the object is not going straight in a line, it travels at speed in an orbit.

  If you want to change an orbit, you need to accelerate or decelerate. This energy has to come from somewhere. And obviously, the direction you accelerate in matters. If you speed up horizontally, increasing your orbital speed, you’ll get further away from the parent, but by moving further away, your orbital speed will decrease and be lowest at your furthest point. Then, if you don’t keep accelerating, you’ll start to get closer to the parent again, which makes you go faster. This is an elliptic orbit.

  If you go fast enough horizontally, you eventually can get so far away that the parent’s gravity influence becomes negligible, and the gravitational influence of another parent matters more. This is called reaching escape velocity. If you leave earth orbit, this is usually the sun.

  If you were to simply slow down the object in its orbital speed, the object would get closer to its parent until it collides.

  If instead of accelerating the object “forward”/horizontal to human observer on earth, you’d accelerate “up”/away from the earth, you interestingly would not cause the object to get further away from its parent. Yes, you’d move higher up, but that would also mean that you equally slow down along the “forward” axis. So as explained before, if you stop accelerating, the object will start being pulled by gravity again until it reaches its now even closer than before proximity to its parent, half an orbit later on the other side. Because it’s now closer to the parent, it has sped up and will then start moving away again, another elliptic orbit has been achieved.

  And if you accelerate “sideways”, so neither away from the surface nor forward along the orbital path, you actually change very little: you only affect the inclination of the orbit. Usually we think of objects going around the equator, but they don’t have to. An orbit can go any which angle, even rotating around the poles, going South to North or vice versa.

  So long story short, how does the moon speed up? It doesn’t have and rocket engines or similar. The reason is the vast difference the earth and the moon rotate around themselves. The earth takes 24h to rotate. The moon takes roughly 27.3 days to rotate a single time. This causes the Earth to “push” the global tidal waves around its oceans much faster than the Moon gets pushed. This actually causes the moon to get “dragged along” a tiny little bit on every tidal rotation. This not only speeds up the rotation of the moon itself: the moon is so slow that it doesn’t have time to transfer all that rotational energy before the tidal wave on Earth has moved on the surface to be a bit on front of the Moon. This is the moment where the Earth’s center of gravity is a tiny bit “forward” of the middle of the Earth. This in turn pulls the moon forward along its orbital path, speeding it up horizontally. Obviously, this also means that Earth’s rotation gets actually slowed down by the same amount.

  All these effects are incredibly tiny! The moon moves “away” at 3.8 cm per year, whereas it will take 50 years for an earth day to be a single millisecond longer.

  A mesh surface is not automatically longer lasting. Quite the contrary, actually:

  Mesh is “less material per surface”. This means more stress is put on the strands than for a full cover upholstery.

  Mesh is open, which over time means that dirt and grime will start gathering in the cushion beneath the mesh. This can end up pretty nasty over the years of heavy usage.

  In the end, it’s always about proper materials: good quality foam exists and are used by some, but obviously it’s usually more expensive. Same for the surface material: there’s super cheap PVC leather that will start flaking off in weeks, and there’s high quality PVC leather that will last a decade. Or just go for real leather if you got the money. All of the closed surfaces have the advantage of being incredibly easy to clean and maintain: simply wipe them with a wet towel. For real leather, only a tiny bit of extra care is needed ( waxing ).

  Technically true, but I think everybody knows exactly what kind of dlc is meant, and because they still make up the majority of dlc content and addon-sized dlcs are so rare, it’s fair to call them that.

  Moneygrab empty dlcs ( shiny horse armor! ) are stupid, and history has shown that people are not fiscally responsible enough to not be lured into spending absurd amounts of money for very shallow or plain empty content. “Vote with your wallet” doesn’t really work in the face of more and more insidious marketing efforts.

  If you have to say it often, it might indicate you have trouble formulating your initial advice in a way that is acceptable to people.

  Nobody likes to be told they’re wrong, so it helps to be empathetic about it. Packing your advice or instructions into a tactful and diplomatic approach doesn’t cost you much, but makes it much more likely for your advice to be accepted and implemented. And the recipient will usually end up being grateful for having avoided a mistake. They might even start to look for your and ask advice in the future. And if you keep doing that, he might even consider you a nice person or even a friend.

  An arrogant and condescending approach will only do harm, even if you are factually right.

  I’ll still use the opportunity to voice my opinion clearly on this: Yes, forced circumcision on infants is only a very small step above the also still common practice of female genetic mutilations at birth/infancy. It does not matter what reasons you claim, only medical necessity should matter. Society should protect its infants from any religion or tradition demanding body modifications of infants.

  Leave people’s bodies alone until they can decide on their own what to do when there is zero proven medical benefit to doing it before without their informed consent.

  The common “improved hygiene” argument is nonsensical. You know what improves hygiene? Washing, and teaching kids how to wash themselves.

  Otherwise you could cut off ears using the same logic. No ears, no need to wash behind the ears.

• ⁨Comment⁩ on ⁨„If companies were to do the right thing, they would lose the most valuable customers on earth, preteen kids”⁩ ⁨⁨6⁩ ⁨months⁩ ago⁩:

  I was about to say… What does “suitable” mean? I grew up in the 90s, and “suitable games” ranged from SimCity or the settlers to age of empires, crusader Kings, quake, doom, unreal tournament or half life.

  There is no need to over protect kids from the “simple” evils: when I was very young, I didn’t want to play violent or scary games, even knowing they exist. Later I got curious and explored them. Depending on your choice a game such as the settlers, age of empires or crusader Kings could well be classified violent and “unsuitable”. But violence is everywhere, and those were some of the games that I fondly remember for instilling a huge curiosity in history and cultures in me. And yes, we were marketing victims as well: everyone spent way too much on Magic, Pokemon or Yu-Gi-Oh cards and related toys. But it didn’t infect every part of our lives.

  Help your kids reflect on their choices and wants. Help them find out why they really want to pay too much money for that shiny Roblox skin. And offer alternatives with free, open content sharing so they realize they are being swindled. Media literacy is much tougher today because companies got much more insidious marketing vectors to infect kids.

  Nowadays there are thousands of games being released per week, in addition to classics such as Minecraft, Terraria, Rimworld, Eco, which still have very strong modding and multiplayer communities.

  I’m curious, why are you “happy it’s been done”?

  I live in a country where we don’t perform this procedure out of tradition/religion, or at least not in the majority. I’m only aware of it being done for specific medical pathologies such as phimosis.

  Because I kind of agree with the sentiment that performing unwarranted surgeries on someone that is unable to voice his (non-)consent is an ethical problem. Even more so with excisions, which always are drastically and usually irrevocably diminishing the body.

  You can disable camera shaking and some post process features such as motion blur, then it’s no different from any other shooter game in terms of motion patterns.

  Speaking of trains: if you happen to drive on a road that parallels a train track, and you see train lights: switch of your brights.

  There’s a train driver in that train, and he has to watch his track just as you have to watch the road. And no, they don’t have magical eyes that don’t get blinded by those bright lights.

• ⁨Comment⁩ on ⁨Brought to you by the vertical mouse gang⁩ ⁨⁨9⁩ ⁨months⁩ ago⁩:

  Depends what you expect. On a pro tournament level, nobody will use a vertical mouse. Usually they are a little bit heavier than regular mouses, plus they have a slightly higher center of gravity. This makes them a little bit more “wobbly” during ultra fast movements.

  However, for regular playing, they work just fine. I don’t play on pro level, but okay competitive shooters almost daily, and I haven’t noticed any real disadvantage. And it helped my wrists enormously, because I’m a full time office worker as well. I decided a couple years ago that the small theoretical disadvantage is not worth the risk of RSI and have been using the cheap CSL/Anker/whatever vertical mouses since. Only very recently I boughta second, regular mouse with more thumb buttons, useful for some sim games I play. I now tend to switch fairly randomly between the two, which probably is even better for hand and wrist.

  Additional info: getting used to a vertical mouse takes much less time than most people expect. Yes, it’s weird at first, but start working or gaming and you’ll stop noticing the different posture very quickly.

  There are many special versions of torrent tools that allow disabling uploading. If course you still have to upload your requests “please give me block 1234 of file XYZ”, which some tools include in the transfer rate shown and others show separate as overhead or meta transfer rates. However, no actual file contents will be uploaded. This is important for some jurisdictions/nations. While both downloading and uploading content is illegal, uploading causes more “damage” ( it’s legally easy to claim proliferation of the uploaded content, multiplying the financial damage). Also, in some countries, it’s either but legal to track user downloads at all or not in a manner that would provide court-proof evidence. Proving illegal uploads is very easy: the legal company will simply use the p2p network itself, but record which blocks were received from what IP address at what time. This list in many countries is sufficient to get a court to order the ISPs to share info on who owned that IP address at that time, opening you up to a lawsuit.

  Thus example is how it works in Germany and must other EU countries. The exact approach obviously differs, because everyone has variations of privacy laws. E.g. not every country makes isps store IP assignment history for longer than necessary for billing purposes ( usually a month), whereas in other countries isps hand out that info even without court orders…

  Educate yourself and act smart. There is no magic protection when doing p2p piracy. Luckily, most companies do not care to pursue pirates. Others ( like kalypso media) are infamous for having partnered with legal companies whose sole purpose is to generate income by chasing pirates with intimidating and expensive “pay 800€ now or we sue you in court for millions” letters.

  Interesting, will have to read up on how that works in Brazil. We also have a separate tax id here ( which is also used for pension and social security ), but that one is even more secure/private than the passport ID. We only provide that to our chosen medical insurance provider ( bc they need to register it with the ministry of finance ) as well as employers ( because 50% of the insurance has to be paid by employers).

  It’s explicitly not allowed and intended for generic identification purposes, because it makes it too accessible for identity theft and associated scams.

• ⁨Comment⁩ on ⁨ProtonMail and SimpleLogin emails will be blocked from registering on websites⁩ ⁨⁨11⁩ ⁨months⁩ ago⁩:

  Where do you live that providing your government id to a business is standard? In Germany, the only one outside of a judge to be allowed to request that is law enforcement ( even then only with proper cause ). Of course, some businesses are legally required to request and process your ID number ( e.g. when booking international flights, medical insurance companies etc), but these are under tight federal control and supervision to ensure data safety.

  Age verification sometimes is a thing for purchasing 18+ things ( media or drugs like alcohol & smokes), but even then businesses will only ever perform a visual check of the date of birth on your ID. Technically they can never demand to hold your ID, not even for a short time just to better read the date. You only have to show them your ID. And actually recording and/or storing any of that information would be insanely illegal.

  Germany / Europe might have its issues, but we at least try and take our freedom and data privacy serious. I would never dream of handing my ID to a generic business like a club for anything more than the age check.

  To each his own. Some prefer the original audio simply because it is foreign, making it easier to mentally dive into a fantasy world. Others get taken out of the immersion by having to read subs and not focusing on the screen all the time.

  Isn’t it weird that EU, famous for being so fragmented that they can’t decide on common interior or foreign policy, all while being ridiculed for their large and inefficient bureaucracy, still is the sole entity that manages to stand up to mega corporations?

  And those are sometimes fights that have zero benefit to a different wealthy elite, but actually protect citizen liberties.

  I shudder to think how the world would look like if EU had not established and enforced the GDPR as well as it does. Consumer protection is probably one of the only fields where the EU had a global positive impact.
