  • NiCd was the one with the bad memory effect that required full charging cycles. They where also really toxic which is why they are illegal in many countries now.

    NiMh hardly had any memory effect left, but would degrade comparatively quickly.

    Li-Ion/Li-Po is what we currently have. They don't like to be full or empty for long times and like shallow charging cycles.

  • The voltage of a Lipo corresponds to it's charge level. So a Lipo at 4.2V (or in case of high voltage Lipos 4.35V) is full.

    Up to ~80% of the charge, the lipo is charged by current limiting (basically, the voltage of the charging circuit raises so that it stays so much above the cell battery that it's charging at a set current). This is the fast charging part of the charging process.

    After the charging voltage reaches the maximum allowed cell voltage (4.2V/4.35V), the charging circuit cannot go above that voltage because it would risk overcharging and blowing up the cell. So the carging circuit holds the voltage at maximum level until the cell voltage catches up. Since the voltage difference shrinks with every bit of charge on the cell, so does the charging speed.

    That's why you only see "Charges the phone from 0-80% in X minutes" in the ads, and not 0-100%.

    This means, that the charger in incapable of overcharging the phone.

    But keeping the charger running even though it doesn't charge the phone anymore wastes energy, so what they do once you reach 100% is that it will disable the charger until the voltage is down to 95%, when it will resume charging. That's why it's quite likely if you unplug the phone after charging overnight, that the battery is not at 100%, but slightly below.

  • Well, anything unpopular that doesn't use any software (even low-level software) that is also commonly used in popular environments. For example, game consoles, embedded devices or car entertainment systems often use outdated versions of popular browser engines. So to hack these, you don't need to be a highly skilled hacker, you just need to be able to try some older vulnerabilities.

    And there are enough malicious websites that will just automatically check for these vulnerabilities. And then it's enough to accidentally open one of these malicious websites and even though nobody wrote the hack specifically for your car, you might catch some malware regardless.

  • Everyone has their irrational topics where it's hard or impossible to be reasoned with. The issue is that it's really hard to spot that with yourself, because in one's mind it all sounds reasonable.

    Many firm beliefs that everyone of us holds are not nearly as much backed by science than we actually believe.

  • That puts your original comment into perspective.

    I don't think there is an argument that could convince someone who wears their gun like it's a religion. They see that as part of their identity, and you can't change that with simple logic.

  • I mostly use solid basic shapes (like e.g. a cylinder) which I modify using extrude or moving edges/vertices and then combine using the boolean modifier, which can do union, difference and intersection.

    Sometimes you have to switch to carve in the modifier to get it to work correctly.

    The important thing is to only work with watertight objects. So for your hollow cylinder example I'd do the following:

    • Create a cylinder with the desired outer radius and height.
    • Create a taller cylinder with the radius of hole.
    • Move both onto the same location. The taller cylinder should stick out on bottom and top
    • Select the outer cylinder -> modifiers -> add modifier boolean -> difference to inner cylinder
    • Select the outer cylinder and export it with the option "Export only selection"
  • It was, 25 years ago. Same as Windows' security was absent at that time.

    But people never update their prejudices, so all the jokes are from the last millenium.

    If you want an OS that is really malware-free, you need to run temple os.

  • Because he put in the same comment, that high street and highway are called that way because they where elevated over the other streets, which is nonsense.

    In fact, high street/highway are that way, because in Old English high didn't only denote elevation, but also a high status/rank/importance.

    Modern English still uses that meaning, but it's rarer nowadays. For example, high society, high sheriff or high priest aren't called that because they are tall.

    High is also used with a lot of words where elevation doesn't matter: high rank, high value and so on.

  • The term high in highway has nothing to do with elevation, but has the same meaning as in "high government official", "high society" or "high priest".

    None of them are named so, because they are especially tall, but because they are of elevated status. Same as the highway or high street.

  • High Street, same as Highway, come from Old English, where high denoted not only elevation, but also status/rank/quality.

    You can see this in a lot of other Modern English words. For example, a high sheriff, a high priest or high society aren't called high because they are very tall.

  • Yeah, the thing is, people in that kind of situation usually stop asking questions or stop using Linux alltogether.

    These toxic fanatics that keep attacking everyone who could use help with using Linux are at least as effective at keeping the market share of Linux low as Microsoft's anticompetitive behaviour is.

    And, tbh, anyone who hasn't had a problem with Linux where they had to spend >5h to fix it probably hasn't done anything else than using Linux to launch a browser.
