They keep the power pack in a shed away from anything too flammable. They could lose the shed, but it would be unlikely to take the house with it.

In some industries companies regularly test their biggest competitors for compliance, then complain to the government if they don’t meet requirements.

The lathe ways (the guides/support for each axis) do wear out, but you can re-grind them to be flat again.

Usually you sell the machine at this point to someone who doesn’t need the precision and get a new machine.

Hue bulbs by default emulate a dumb led bulb. This is configurable so you can have them be “dumb” in a way that you prefer, eg: customize color, brightness or do whatever you told them last.

I have several that some of the time I use a regular light switch to turn on/off and you wouldn’t know they weren’t standard led bulbs.

Toner cartridges generally last a few thousand pages and are much more tolerant of infrequent use than ink cartridges. Unlike Ink cartridges, laser cartridges don’t dry out or need to waste ink priming. The image drum does need to be occasionally replaced (not often, 10k+ pages), though if you tolerate defects in prints it can last longer.

How well non-original cartridges work is highly dependent on the printer model. Some have more complex authentication of the cartridges and others it’s a simple page counter.

The main downside is color is a significant increase in cost of the printer as fairly expensive pieces need to be duplicated for each color.

It primarily has to do with the physical construction of the magnets, in a toroid the inside of the toroid effectively has more windings per meter of circumference than the outside causing uneven containment.

With mobius strip you regularly flip between inside and outside, so the plasma particles get more even force applied.

If the discharge circuit is not present/functional, it can be months[1], even if the capacitor was discharged at one point.

When working with high voltage/power equipment, its best practice to keep the capacitors shorted while you are working to keep dielectric absorption from “recharging” the capacitor to 1-15% of its rated voltage.

If Baumol was solely the reason for increased prices, I expect the increase to be more in line with the increase in prices for hiring tradespeople or other professional services.

They don’t need to even do that, just occasionally send the train past a thermal camera and look for wheels that are warmer than average.

It’s more than twice as losses are lower boosting 220v to the 400v or 800v the pack actually needs.

As an example, a charger in some EVs is 87% efficient when charging from 120v and the same charger is 94% efficient when charging from 240v.

Nope. If your car lost power for whatever reason, the system would scavenge power from the inertia of the car and the brakes would still operate as they do when the car is operating nominally. The 1-10w needed to run the braking system is a rounding error in comparison to the 4-10kW of wind/rolling resistance at freeway speeds.

To lose local regen braking derived power requires a failure of the cars systems similar in nature to one that would cause loss of hydraulic fluid or air in a traditional braking system.

Edit: made more concise.

Having no power would be hard as the brake system can easily generate power to operate itself if the vehicle is moving (and if its not moving that is what the parking brake is for). This is more of a scenario that occurs when there is a catastrophic failure in the braking system, such as the motor control electronics getting damaged.

That would be the default of this system if the brakes are still able to communicate with and provide power for the brake pedal. Basically if the brake system lost external power, it would get the power needed to run via scavenging it from the motors. Once the vehicle came to a stop, it would then loose power and the parking brake would then engage.

The slam on brakes case would only trigger if there was gross damage to the braking system, where you might have bigger things to worry about.

Most EVs have permanent magnet motors of some flavor right now (some have both a PM motor and a pure induction). I would assume that if you were having the motor be the primary braking system, and it was induction, there would be a tiny cheap magnet installed in it to generate bootstrap power to prevent exactly this scenario.

That is easy to accommodate as you can design the electronics such that when there is no power they cause maximum braking force and dump energy into the braking resistors. This can be done completely with power taken from the motor itself and if it’s not turning to generate power, then I would expect the parking brake system to engage, eg: a spring defaults it to “On” and power is used to keep it disengaged.

I could not find anything that would prevent this in my brief skim of FVMSS 105 (US car brake regulations). The regulations are mainly about the performance of the braking system (eg: needs to stop car 10x from 60mph in under a specific distance) and only care a little about the specific technique.

You should see what you propose on cheap cars if motor pricing becomes less than the cost of regular hydraulic brakes.

Downloading the orbital parameters can be done via the internet rather than at the 50 bps that the satellites broadcast them at.

They have also been the cause of fire[0] on the Mir space station. They make for a reasonable emergency oxygen supply (no working infrastructure required), but you don't want to use them regularly due to the fire risk they represent.

The Valve Index does 1440×1600 per eye and it probably needs to be at least double that before artifacts become hard to notice.

It’s easier to use weight instead of volume if you want measurements more precise than a 1/4 cup.

Most home ovens struggle to hit the set point to within 25F for most of their internal volume. They also have large swings in temperature as cheap heating elements do not respond quickly.

I think the idea is to reduce (its reduce, reuse, recycle in order of preference) as a bag of toner needs less resources than a cartridge.

The internet indicates a 5k page cartridge costs ~5kg of CO2 to make, and each trip to the recycling center costs ~1kg of CO2 (rough average cost of shipping a package).

A 5k page pouch in a box weighs 0.2kg, assuming a 4x weight->CO2 cost (high end of plastic production), it comes out to 0.8kg of CO2 per pouch. This is less than the CO2 cost of shipping back the cartridge for recycling.

If you assume the cost of return shipping and recycling is free, the cartridge will need to last >6 times to be worth it from a initial cost perspective. The figures I can find on cartridge lifetimes is 3-4 recycles before they are too worn to recycle again.

Even though its single use, its still a net win from a lifecycle perspective.

On a desktop in Chrome, with a fairly powerful processor, its taking ~4 seconds to show the calculator after it makes the call to Uno_UI_Windows_UI_Xaml_Application_Start_Windows_UI_Xaml_ApplicationInitializationCallback.

It’s currently illegal to fly past Mach 1 over land barring a few exceptions (eg: military training areas).

In general the slow part is getting the data out of the ADCs, so by interleaving multiple you can increase the speed. To reduce costs, if you have a repetitive signal, you can trigger the ADCs at different points in the waveform to build up a better idea of what is going on.

For scopes that can do these high sample rates they frequently use two lasers and have the scope capture the beat between them as a demo of how fast they are.

Ideally the write enable line of the flash chips would be hooked up to their respective application processors, so when you are reading them via this header they will be read-only as the processor would still be powered down. For an adversary that is able to remove soldered chips there isn't much you can do without going completely custom for everything.

Having sockets would increase the costs ($1-20/flash chip) and doesn't raise the sophistication level of the attacker from unskilled labor (literally anyone in the chain of custody) to skilled labor (eg: someone that can do SMT or BGA rework).

It would also help if there was a standard header on the mainboard that you can use to verify all of the flash chips when the computer is powered off to minimize the amount of the computer you have to trust.

While some may argue that this header would be the perfect place to install a implant, doing so is vastly harder than popping some manufacturers computer. Also, since the header will be specifically checked by some users, it becomes a very risky place to install an implant.

The actual FCC document contains the specifics of what he did in the “factual background” section: https://docs.fcc.gov/public/attachments/FCC-22-43A1.txt

It looks like the FCC has plenty of hard evidence, and they are not making stuff up to fine him with.

Most storage media (DRAM[0], SSD, etc) do reads by pages anyways, so processing other bytes in that page is fast as they have already been fetched.

If the thermal plant uses clean fuel (eg: gas fired) the CO2 in the exhaust would be useful for the greenhouse as well.
