Batteries are bounded by more predictable chemistry more so than something like the breakdown of a mechanical based trigger waiting for rust or decomposition. Chemistry makes it easier to model and predict. If you've got a 1Ah battery and it consumes x watt hours per hour, then it takes y days to burn through. Tolerances that cause the battery to have slightly more or less capacity or component power consumption will likely be <5%, thus not radically different because nobody is timing this to the minute.

If it becomes more expensive to buy products manufactured in certain countries then customers would naturally change their buying habits to other companies. The price to the customer ultimately acts as an incentive to companies.

I could connect a smart plug and disconnect it if below -15, if that would help

If you didn't know already, many smart plugs are not rated for the amount of power that fridges and other compressor based appliances. They can overlosd the plugs and cause failures or fires. Also shutting off a compressor mid cycle increases the wear.

These pictures remind me of YouTube thumbnails with fhe style of over emphasized visuals and it makes me wonder if people got accustomed to that style and that makes it easier to pass the BS test.

Just think of all the countries and companies that grab this data, group by email address, then start to identify preferences of people around the world. Its not just for identity theft. The possibilities are endless! And horrifying.

I'm not an HVAC technician so I wouldn't know exactly, but I think there's two things to consider: static pressure and duty cycle. Static pressure is the fan working hard to spin which causes wear on bearings. Duty cycle is how long the machine runs. If your duty cycle is too low then the machine is turning on and off quickly which is bad.

You could look at the size of the unit and there's some rules of thumb that translate size, climate, and square footage of just the areas you leave the vent open and there are online calculators you can use.

I think the only way to know for sure is to measure the pressure drop across the intake and outflow and see what the fan motor is rated for.

Depends on the unit and whether it was over sized or under sized for the space, but restricting 60℅ air flow is a lot.

Another thing to consider is that if you later want to heat up the entire house, the unit has to work harder. Sometimes it can be more efficient to just keep the house close to your target temp.

Yeah there's a few reasons why the offer that wins the buy box (the term for which merchants offer is shown to the customer prominently) and is complex, but I wouldn't consider it particularly sinister or designed to mislead. If one person has prime and the other doesn't, it might weight more towards a prime offer which may be more expensive, a price from a merchant may have changed, or gone out of stock.

They're forging the GPS to look like it's in the EU. Do we turn off all the EU terminals too?

I'm a little surprised they can't identify spoofing by comparing the incoming signal to the proposed location. They already have antennas that can be steered using the phased array.

It's possible, but it costs money to design the hardware so it's accessible, it has to use a connector which has to be robust against vibrations (is m.2 robust?), then there needs to be a standardized protocol to communicate with the card. Does the car computer need to know how to authenticate against the cell network or does the card? Is it industry standardized or specific to the manufacturer? All kinds of things need to be designed and car manufacturers have no reason to invest in they.

The problem is the cell modem in the car, which is hard to replace. Cars last a lot longer than phones do. When whatever network that the car uses shuts down, then you can't remote start your car. That's a marginal cost that the car company has to pay for.

CDs have an advantage over USB drives in that they can't actually secretly be USB HID devices like a fake keyboard or mouse that runs a bunch of commands when it plugs in. It's only a storage device.

A super secure environment might then lock down all USB devices to ones known by them and then epoxy all ports and devices.

Great if only my family would even believe this as opposed to just saying something about FEMA using DEW and HAARP and space lasers to actually create hurricanes to be able to extract lithium or something.

ICANN specifically set aside all two character TLDs to be for country specific codes. There's only a few cases where they kept ex countries TLDs around and phased them out over several years. It would be an entirely new precedent if they did keep it. So I wouldn't depend on it

I have my doubts that a company would be able to just abandon a live and operational nuclear power plant. I'm no nuclear or power engineer, but I am familiar with data center power consumption. There are companies in the region that would absolutely build more data centers, but are power constrained from the utility companies in the area, that are not just for AI, but for general compute. Even then, it's low carbon production energy. If you have a ton of excess power, just start forcing high carbon production facilities in the area to close and now you've greened the grid.

Computer algorithms solve problems all over the world for companies already. I bet airlines already have teams of people using computer algorithms to figure crew management, flight routing, cost optimization, etc.

The fact that they're exploring quantum computers and non-classical algorithms just suggests that gate allocation is NP-Hard. Sure things go wrong when computers fail already, Look at Southwest or Delta's recent meltdown, but to act like this a bad thing is just nonsense. This should be looked at as a good thing that airlines are working on.

Why do you think this is going to replace air traffic control work? It's picking which gate to park the plane at. This was done by airline and airport operations teams, not ATC. Imagine if you could automatically pick gates to reduce the time a plane spends taxiing and/or minimize time passengers spend walking. That's 100% a useful application for computer optimization algorithms. Humans aren't going to do that better and it's not a function of safety that tower or ground control needs to do.

While I'm not a fan of the loan nor the massive waste of power most LLMs are, I actually think that's its a good thing because if Microsoft can break through some of the excessive red tape on nuclear plants then they'll bring this online and hopefully prove that nuclear power can be safe and a good source of large amounts of power, when the huge demand for AI dies down, then maybe they'll keep the plant around and provide power to the grid.

On Android, you can specify which applications you want included or excluded. Or you can specify that you only route your home LAN IP ranges through wireguard. Both of those would accomplish your goal.

Kind of but it's not fair to put it all on the manager. Multiple people decided to hire the person. Somebody else approved that code review. People approved the technical design. Why didn't the tech lead raise concerns with the manager about someone's under-performance, etc. it's unfair to just put all blame on the manager.

The idea of extreme ownership is about not saying "not my problem I won't do anything" or blaming your reports. It's about saying I can and should do anything and everything in my ability to fix problems.
