Torque sleep only makes sense for dual engine models, definitely not "the entire fleet". Could be part of the announcement (torque sleep is overdue), but there has to be more. Something that also applies to the single engine models.

Torque "sleep" may refer to a new motor control algorithm. It would work just fine on the single motor cars. Basically apply torque until speed reaches the setpoint, then turn the motor off. Only "wake up" and apply torque when the speed drops below the setpoint. If you do it quickly enough it is unnoticeable. It increases efficiency because it automatically takes advantage of tailwinds and downslopes. The same thing could be done with an i.c.e. car as well, without as much benefit, by stopping fuel flow and ignition on a short-term (milliseconds) basis.

My dad designed, but had an architect complete the details of, the house I grew up in. We moved in in 1967. The house has plunger switches in the door jambs of the closets. Open the door, the light goes on. Close the door, it goes off. Very simple, and very effective as long as you are willing to keep the closet door closed most of the time and go without light if you go in the closet and close the door behind you.

As for X10, I was an early adopter, starting in 1979. I've thrown away many defective X10 devices (controllers, lamp modules, appliance modules), yet those closet door switches still work. Not saying automation is bad, just not robust enough yet.

Please provide reference(s). I have never seen any indication of this, or at least there is no read limit for the flash memory itself. You can read from it indefinitely just like static RAM, without "refresh" as required for DRAM.

Here we go again (same discusion on Slashdot several years ago). Everyone can see 24 Hz. flicker. I seriously doubt there is anyone on earth that cannot. This problem was solved long, long ago by flashing each movie frame on the screen 2 or 3 times, then switching to the next frame. 3 x 24fps = 72 Hz. This corresponds perfectly to the fact that, for most people, a CRT refresh rate of 72 Hz. or so is comfortable. For example, the Eumig S710D Super 8mm film projector from the 1970s has a 72Hz. refresh rate due to its triple-slotted shutter.

Passage of these bills effectively bans drones and video camera guided RC (Radio Control) aircraft because cameras are used for navigation, not just taking photos of objects of interest.

Useful applications of privately-operated drones and RC aircraft with cameras include roof inspection and birds-eye view promotional shots for real-estate listings.

Making these devices illegal will cause more harm than good.

My first computer experience (1972) was at 110 baud, banging away
on an ASR-33 Teletype connected via leased line to a DEC PDP-8 running Dartmouth Basic.

I'd get up and run a lap around the building for fresh air while printing
a program listing. Data rate in/out was 10 CPS (Characters Per Second).

I recall proudly showing my dad the program listing at home, unrolled on the living room floor at about 10 or 12 feet long...

Reliance on tools of this nature will reduce the quality and clarity of the source code. The programmer will have little motivation to use descriptive variable names or constant definitions.

This is evident in the video. You can see the use of integer literals everywhere instead of symbolic constants.

How about writing up a tutorial on how to correctly declare
c/c++ numeric variables. When I went to school many moons
ago, int and long were it.

has a tutorial on declaring variables, and a table listing sizes.
They state the sizes of char, short int, int, long, etc.

If this is not the correct way to do it, please help enlighten us!
Thank you.

It is not well to be thought of as one who meekly submits to insolence and intimidation.
