  • The device needing more power won’t get it, simple. Depending on what device it is, it will automatically throttle down so it needs less power, but obviously it will also deliver less performance while so throttled. And if the power is missing during a very sensitive part of a process so there’s no time to throttle down, your PC could blue screen or restart.

    It’s very unlikely to suffer any long-term damage from this.



  • Why do you consider telegram private? It’s a pretty bad option for that. They are only using true end-to-end encryption when using the explicit “secret chat” feature, which is limited to one-on-one still, afaik.

    “Normal”/default encryption gets resolved on telegram servers, so your clear text messages are sitting there for them to do whatever they want. Given that telegram is based in UAE and has knownRussian management influence,I’d be extra hesitant.

    It also is for-profit and closed-source for the servers ( only clients are open source), so nobody knows what the servers really do.

    If you care about privacy, go use Signal or any Matrix-based messenger such as Element. Especially because they lack zero of the comfort and usability that Telegram offer, but are much more secure.


  • 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.


  • Inherited a Hilti Hammer drill from my dad that was used for basically everything in construction and demolition he ever did since before I was born - around 4 decades ago. It was and is the tool he and now me always go to when cheaper drills can’t deal with the problem. Be it hammering through super massive concrete walls or enduring hours-long destruction sessions, it just does the job.

    Nowadays it looks like a utter piece of junk that got tumble dried with rocks, but it’s as reliable as on day one.


  • 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.



  • Regarding the profit incentive: providing free school lunches or medical/ hygiene supplies does not hurt profits. As the meals/supplies will still have to be sourced from the market, it probably will now be a few big contacts with big suppliers that will cover entire school districts.

    The costs of these contracts will be a public burden unless they implemented a specific focus tax to pay for it, so it will come out of various broad tax pools. This means everyone pays a little bit so every kid has something to eat. Even if you don’t have any kids or if your kid gets homemade lunch packs. This is where the “social” aspect comes in.

    Other countries, many of them European, actually go a step in the other direction: if you do not have kids, you actually pay a premium on your income tax. And that is generally accepted, because for society to live on, obviously kids are necessary. And if you don’t support society by raising kids, you at least help cover some of the associated costs. These premiums are explicitly used to fund kindergartens, schools etc…

    An often valid capitalist criticism of public large contracts on infrastructure such as this is that the public offices tend to be notoriously bad negotiators, accepting worse deals than private companies would. This is because there’s little to no incentive for them to reach good terms. It also makes the process more vulnerable to corruption and politicking on a grander scale. These are not guaranteed to happen, good governance can definitely avoid this. But public governance simply isn’t that great to begin with in many areas.


  • But it’s not really true. Switzerland has no naval branch of its armed forces.

    It has a dozen or so of 10t patrol boats armed with a single 50cal MG for its lakes, and those are organized in a single motor boat company, which is staffed and manned by the military engineers branch.

    Their duties are supporting the border guard (police) on the lakes against trespass/ smugglers and assisting (civilian) search& rescue.

    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.



  • Laying even 10 times the cable should not be more difficult when you have 60 times the total population (335mio in US vs 5.6mio in Finland) and hence more resources.

    And sure, Alaska definitely it’s expensive and inefficient to service, having a pop density of about 0.5 inhabitants per km². But unlike Northern Finland, most of Northern Alaska is in fact entirely void of human life and more akin to a desert. There really mostly are a handful of oil industry clusters and native communities. And still, the extremely low pop density means it’s only 730 000 people living in Alaska. That is 0.2% of the entire population of the USA. If you were to completely ignore and not service Alaska, you should have a an even easier time providing service to the vast majority of the US population in all the main states. I think it’s pretty clear this is a political failure and not a matter of financial resources or natural obstacles.


  • You are absolutely correct that distribution matters. However, Finland has an even more uneven population distribution than the US. 75% of the population lives in the costal cities, with 30% of the entire population living in the capital region( density of 193 persons/km²). The entire rest of the country is not empty dessert ( which would require no services), but very sparsely populated rural woodlands, down to 2 people per km².

    Density still is an overall useful quantifier given that extra knowledge, as providing services for a small population of only 5.6mio inhabitants is not easy either. Sure, providing coverage for the 75% in the cities is fairly easy. But that still leaves 1.5mio rural residents, which require huge investments in cable to supply with broadband. And due to the vast distances, you definitely cannot cover them with wireless alone, if you were thinking that.
