  • I kinda agree, you are "allowed" to sing or dance or paint just because you want to and not to get good at it, nobody is going to yell at you for that.

    But on the other hand I feel like a large amount of people won't even try something for fear of being bad at it. I don't think they explicitly think of it this way but "the only point of doing something is to be good at it" is the implication of that attitude.

    (That's not to say that you shouldn't seek to improve your skills if that's something you enjoy. Just that 'trying to get better' isn't a prerequisite for doing anything at all. You can have fun and enrich your life while sucking at something.)

  • Ummm… 10 knots * 200 = 2000 knots. I don’t think so lol.

    First of all, kinetic energy scales with the square of an objects velocity.

    Second, since we're talking about a continuous stream of fluid instead of a single object, increasing the air speed not only increases the enegy per unit mass of air, but also the number of units of air per second that pass through the turbine. Which means that the amount of energy extracted scales by the cube of the wind speed.

    So, more like going from 10 knots to 60.

  • This seems like it’s not going to be a productive conversation if you’re going to accuse me of using a strawman argument.

    It seems like its not going to go anywhere because you think of all human communication as an act of manipulation.

  • When you wanna watch something but for whatever reason using a big screen is inconvienient, would you just watch it on your phone or wait till you find the time to watch it on the big screen?

  • It would be a matter of what kind of video it is and what situation I'm in.

    Generally I watch almost everything on my desktop PC, but if I'm away from my computer and I also have to sit and wait for a few hours I might watch something insubstantial (not a movie or something) on my phone using an earbud. That is if I'm not using my phone to read instead.

  • I am reminded of this story:

    https://retractionwatch.com/2024/02/05/no-data-no-problem-undisclosed-tinkering-in-excel-behind-economics-paper/

    Heshmati told the student he had used Excel’s autofill function to mend the data. He had marked anywhere from two to four observations before or after the missing values and dragged the selected cells down or up, depending on the case. The program then filled in the blanks. If the new numbers turned negative, Heshmati replaced them with the last positive value Excel had spit out.

    Of course that guy didn't need fancy autofill to act like an idiot, he used good old fashion autofill.

  • Games you fell out of love with.

  • I fell out of love with Team Fortress 2 after they murdered the art style with the cosmetics and extra weapons.

    I didn't realize it at the time but later on I fell further out of love with it for its role in normalizing lootboxes. In retrospect we should have shut that shit down as hard as horse armor was. Tribes: Ascend and TF2 were patient 0 and 1 in the pandemic. It was seen as acceptable at the time since the games were free, but we didn't anticipate the broader effects it would have.

  • New nickel-iron battery charges in seconds, survives 12,000 cycles

    Jump

  • Late 19th/Early 20th century had about 1/3rd of all cars on the road be electric.

    Long before lithium batteries were ever a thing.

    You want to tell me what the top speed and range of those cars were?

    Also, Theres a much higher demand thanks to the modern resurgence of electric cars, for better, cheaper batteries.

    I think you'll find that the first modern resurgence in EV interest came in the 1970s, with the 1973 oil crisis.

    If you research the history of battery technology I think you'll also find that it hasn't been static since 1900 with lithium ion popping up out of nowhere in 2008. In between we had things like nickel metal hydride cells, and for a few years before Li-ion became practical there were even some EVs that came with the option of molten salt batteries (called "ZEBRA" batteries) for extra range. Those things needed to be heated to 572° F in order to function. Nobody would have done that if they could've just instantly pulled a better battery technology out of their ass like you seem to think they can. By the way, the name "ZEBRA" comes from "Zeolite Battery Research Africa", the scientific project that invented them, which was started in 1985.

    Just like computers have much increased demand for ram today than they did in the 1970s.

    I promise you that people wanted more computer memory in the 1970s.

    While we're on the topic of computers though, do you know what the current state of the art is in chip fabrication? It is extreme ultraviolet photolithography, or EUV.

    The first commercial product made with EUV was released in 2019 (the Samsung Galaxy Note 10) but the first EUV demonstration took place in 1986 at the Japan Society of Applied Physics. Originally they thought EUV would be ready by 2006, but it took an extra 13 years to develop.

    Notably a number of other technologies, like contact lithography, electron beam projection, ion beam projection, and proximity x-ray were being developed simultaneously, in competition with EUV. EUV won out in the end but for a long time people were not sure which would be the most practical to implement.

    So yes, the pop-sci articles written about stuff like this are stupid, but the idea that things are fake unless they can move from the lab to the factory floor within a year is just not how the world works.

  • Even if they could be used for something productive that's impossible now because of their extreme over-use and abuse.

  • Research into the lithium ion battery started in the 1970s and they only became common in EVs in the 2010s.

    So yes, it would "take long" for companies to "jump on them".

  • 15 years I think

    This number gets lower every time I see it.

    First, manufacturers typically guarantee their panels for 25 to 30 years.

    Second, while we can extrapolate from existing data and perform accelerated aging tests, we're actually not completely sure how long PV panels last in the real world because the oldest ones from 1987 are still going.

  • Its at least somewhat based on the transistor density increase they get from other techniques right? Like "3 nm" is the equivalent transistor size they'd need to get the same transistor density using 2005 chip design.

  • I had a very similar childhood in the US.

    I sat at a booth and played with coloring books while my mom worked in a restaurant's kitchen, dad's work was seasonal and very irregular. We didn't drink the tapwater in our little town because it didn't smell right and even came out discolored a few times; instead we'd drive to springs where a bunch of other people got their water too.
