  • You’re passionate about something you don’t understand and have never tried.

    Tap to click you remove your finger and press it back down to click. That’s why it’s called tap to click and not press to click.

    With haptic touchpads you keep your finger where it is and apply more force. It’s a completely different gesture and is very similar to mechanical clicking touchpads.

    Why it’s better is because it is consistent across the whole touchpad surface versus mechanical typically don’t work towards the top of the touchpad. Mechanical touchpads normally feel loose to me and you can’t change the actuation force. With a haptic touchpad you can change the actuation force since it’s a force sensor with a software defined threshold.

    It also doesn’t feel anything like phone haptics. It feels more like a press than a vibration like a phone does.

    These are also higher quality touchpads in general that have more resolution. Theoretical even better than the Apple force touch devices I have used.

    Walk into an Apple store and try one of their devices before you complain again.



  • Except piloting a plane requires actual skills. Plus actually flying the thing isn’t even the hard part, it’s not that much more difficult than driving a car from what I understand. The difficult parts are doing paperwork, setting up the plane, dealing with ATC and passengers, and most of all finding a way to fund all the training and building up the flying hours without going broke.

    Before any commercial plane takes off all kinds of performance calculations are done and flight plans are filled to make sure it’s actually safe. Load and balance plus fuel checks all have to be done. Pilots need to plan and brief on emergency procedures and so on, this is also done prior to landing.


  • Volts don’t measure power. Also nobody specified the load was resistive. Most loads are not resistive. See light bulbs, diodes (inc. LEDs) and even electric motors as an example. If you are talking about resistive loads you need to specify that. For a resistive load doubling the potential difference (volts) causes the current to also double because I = V / R and power to quadruple P = VI. So run time would half since you are spending double the energy at four times the power (power is rate of energy consumption).

    I am now disappointed in people who call themselves electricians.


  • Similarly, batteries, for an example, wired in parallel will give you more power for less capacity, while batteries wired in series gives you more capacity but less power.

    You have no idea how batteries or electronics work. Adding in parallel increases capacity and maximum current and maximum power. Adding in series increases emf (volts) and maximum power and capacity. Adding extra batteries almost always increases capacity in some way. The actual duration is as much about load as capacity.

    If your load is something like a resistor then adding batteries in parallel will increase duration since current draw and power output stay the same and capacity has doubled.

    If your wire in series then current draw will double and power draw will quadruple because the potential difference (volts) has doubled. This follows I = V / R and P = VI. This also means the duration is halved because the power drain is 4x but the capacity is only 2x. Make sense?

    I = Current

    V= Potential difference (p.d) / electromotive force (e.m.f) measured in volts

    R = load resistance

    If something supplies power you call it’s voltage electromotive force, if it uses power then it’s called potential difference. Why is it this way? No idea

    Please note I am not factoring in internal resistance and some other factors here because that makes things way more complicated.

    Also you can measure battery capacity in two ways: amp hours and watt hours. Only one actually tells you the total energy stored, which is watt hours. To work out watt hours from amp hours you need to multiply it by the nominal imf (volts) of the battery.




  • Not everyone left of centre is a ML.

    I never said that they were. It primarily seems to be MLs attacking liberals and everyone attacking MLs.

    Liberals are not left wing.

    Depends when and in which country you’re talking about. In America at current they are an odd party that don’t seem to stand for much, in the past they have been more left wing. In other countries I am not really sure as liberal isn’t a well defined term like neoliberal or libertarian is. You could take it to mean socially liberal in which case it could be a left or right wing position much like a libertarian could be.



  • It’s almost like no one remembers that redneck meant socialist union organizer before it was corrupted to truck loving suburban hillbilly wannabe. The working class is ripe for radicalization, but you have to treat them like full people first, not caricatures.

    That’s not what redneck originally meant at all. That usage came later in the 20th century. Have a quick look at the Wikipedia article.


  • Have you tried updating the kernel? If it’s been rated to work with a certain Linux distribution and it doesn’t work on yours then chances are that the distribution they tested with is using a newer kernel.

    That being said new hardware can be quite problematic on Linux. I personally haven’t had issues with Huawei Matebooks provided I installed the newer kernels, but Apple Silicon was a nightmare.
