We still use controllers for most video games over keyboards/mice or touch pads for a good reasons related to how games are played (from a couch vs desk) or the types of games. No human computer interface is a panacea. It should always be a mix for any complex system, not either/or.

>We still use controllers for video games over keyboards/mice Not that good an example, at least for first person shooters.

I'm sure the vast majority of FPS players are using controllers...

Yes but instead of worrying about the theoretical EMP that has never happened and will never happen how about we worry about the fact that we keep crashing into merchant ships like on the regular? Engineering priorities and all that.

A geomagnetic storm is not an EMP. They are completely different phenomena.

A geomagnetic storm is a very long duration, low frequency event that causes movement in the magnetic field of the earth. This can induce a voltage on large conductive structures notably very large metal objects, but primarily on long distance electrical lines such as telegraph (in 1859), or electrical transmission lines today.

An EMP is an incredibly high-frequency, short-duration event in which a very intense electric field is generated which can affect mostly very small electrical devices such as integrated circuits, etc.

They aren't even vaguely similar.

Honest question: Why don't modern cars yet monitor humidity in and outside the car and make the correct decisions to keep your windows clear? Why are we focusing on self-driving cars while our cars are too dumb to do this much on their own?

Because when the sensor goes screwy I don't want my car to start flipping shit like the defroster on when it's not needed? Because manual controls make such automation totally unnecessary? Because even if the automated system were designed to be "fail safe", the state that's 'safe' is actually context dependent, therefore manual controls will be necessary anyway? It ain't broke, so stop trying to 'fix' it.

The problem is the current solution doesn't work. Because trying to perfect those settings manually while driving in near zero visibility is scary and dangerous. And nobody even knows the correct settings to use! There are YouTube videos testing whether cold or warm air is the fastest way to defrost and/or defog your window, because nobody knows or remembers.

I honestly don't remember and my solution is "try both for a little bit while maintaining control of the car".

Tactile is better.

That's also the lesson electronic musicians found out over time.

You can still use MIDI/VST/synthesizers/DAWs and so on -- but having tactile control over them is better (faster and more expressive) than a tiny, or even a large, screen.

And of course, you can combine both methods (but not when you're just given a screen).

This is why I detest touchscreens for most car functions. Specifically AC, with old fashioned knobs I have full control over AC without taking my eyes off the road, but nowadays everyone wants to put it on their infotainment system, hidden beneath 4 other buttons.

Yesterday I was driving back from Scotland to England, doing 70ish, when we ran into a really heavy thunderstorm. Went from good visibility to almost zero in seconds, and the only thing I could properly see was the crash barrier alongside the lane. I found myself desperately trying to see where the road was, simultaneously trying not to get rear-ended as I slowed up, switch on the rear fog lamps and hazards, max wipe…

Honest question: why didn't you take the train? This would have been a good time to take another sip of your whisky and soda.

Recently I've taken up metal machining as a semi-serious hobby. Fully automated CNC machines don't entirely fit my use-cases but for a couple of them LinuxCNC works fine. The primary UI for LinuxCNC is a touchscreen and frankly it's a frustrating limitation. LCD Touchscreens are just not well suited for that sort of environment. Legit OEM CNC controls are better but honestly every time I use one I can't but feel like…

I’ve hooked up a PlayStation 3 controller to my LinuxCNC-based mill, and it’s become my primary working interface.

I only use the keyboard when I’m editing config or loading code.

Automatics are great when they work. I do have automatic wipers, which usually work pretty well. Fortunately they didn't remove the manual controls though because I had a boat on the roof yesterday, and the rain sensor behind the rear-view mirror didn't really see as much rain as I did.

There is a max-demist button, which for me is the perfect automatic function - it says what I want, and lets the car get on with selecting max fan/heat/AC/flow to the demist vents. And I can find it with muscle memory when I need it.

It isn't caused by any specific humidity levels. While it is depositing water droplets on to the glass surface, that same water is normally suspended harmlessly in the air (it is effectively de-humidifying the air onto the cold windows).

It is caused by the glass's surface temperature being much lower than the air temperature inside the car. Humans are warm. The air we breath is warm. We're heating up the interior of the vehicle. When that warm air contacts the cold surface of the glass, the water droplets migrate from the air onto the surface.

In order to detect it you'd need to know the glass's surface temperature ideally in the middle (away from the car's body) and also know the interior temperature. The interior temp they already have. But figuring out the glass's temp is non-trivial. Infrared camera is the only thing I can imagine working (since a sensor wouldn't be transparent or wouldn't be replaced when the glass is) but that would likely give inaccurate readings due to the outside temperature.

You know, I think touchscreens are not preferable unless you need/want to be able to have controls for many different systems in the same space (e.g. a smartphone with multiple apps). If you are needing a dedicated control for a high-stakes system, the fact that it's a more modern-looking interface should not matter. Touchscreens are inherently inferior to a mechanical interface, if it's a single-system (i.e. doesn't…

I agree, and would add that a case where the UI is evolving and you want to be able to ship functional updates and changes easily is another 'use a touch screen' indicator.

Which is why you have such a wide range of physical controllers for DAWS.
