That’s why most boat power systems use LiFePo4 (aka LFP) batteries instead of LiCoO2 like you phone battery. LFP is immune to thermal runaway, and can’t burn even if it did overheat.

Boats with electric motors don’t need a dedicated generator, as the motor can act as a generator when you put it in neutral. (If properly configured.)

Sailboats can operate at lower power levels, because their displacement hull is efficient at low speeds. (Where a planeing hull needs higher speeds to get more efficient.) When I had solar electric sail boat, I could motor at 2 knots with no wind using only 500w of solar without touching the battery. I usually ran it at 3.5 knots if there was no wind, which gave me lots of range on battery for a full day on the water.

They also have the sail as a primary power source when there’s enough wind, so you don’t always need the electric motor. Sometimes, if the wind is strong enough, you can use the water turning the propeller to generate electricity to charge the battery. Or if the wind is light, you can use the motor to add more speed than sail alone, using less battery than using electric alone.

They have one other advantage: unit price. But Lithium is rapidly catching up, and is already better if you calculate price per lifetime charge cycle.

It’s also checking your other traffic. (Since Cloudflare handles traffic for so many companies.) Are you visiting other sites in a realistic fashion, or are you doing 99% of your traffic trying to do one thing over and over.

Others mention the mouse motion, and monitoring your other traffic to similar sites. When it shows the checkbox, it has already determined you are probably human. If you had suspicious activity, they will give you more advanced tests instead of just a checkbox.

Spoilers in Connect are not readable when I click them. (White on white) Unless I first select the post so the background in grey.

It’s a third party kernel module, which Microsoft would love to be able to block, but legally can’t. It’s technically possible to write a virus scanner that runs in user space instead of the kernel, but it’s easier to make sure everything gets scanned if it’s in the kernel.

Because most of what you look at in real life is mundane. But go find a nice sunset or a green forest, and you can appreciate it. When you see a scene in HD or 3D on the screen, there is a heavy selection bias to show you pleasant scenes that most people seldom see in real life. If it was super 4k and 3D, but it was just your same living room you see every day, it would be uninteresting. But the same camera showing a living room in a 10 million dollar house would be interesting. (And the natural views outside even more so, most likely.)

This actually exists, but for a different operating system. The AS400 (aka iSeries) had a command line where programs had a standard way to specify parameters, so that pressing a prompt key (F4) would allow you to build the proper command line by filling a form. I do miss that, pity it doesn’t exist for Linux.

I’m saying it’s happened before. AOL. Palm. Yahoo. Blackberry. A company with an effective monopoly gets complacent and fails to serve their users. They get replaced.

But that’s also a path for them to no longer be a monopoly, if the right competitor makes the right moves.

You can do that kind of imposed structure if it’s an internal tool used by employees. But if the public is using it, it has better be able to parse whatever the consumer is saying. Somebody will say “I want a burger and a coke, but hold the mustard. And add some fries. No make it two of each.” And it won’t fit your predefined syntax.

It’s more than voice recognition, since it must also parse a wide variety of sentence structure into a discreet order, as well as answer questions.

That sounds more like they are excluding most corporate internal systems, (which would also happen to cover the systems run by government.)

They don’t want you if you’re not watching ads or paying money. They don’t want to give you bandwidth for free.

People do sometimes get electrocuted in fresh water, but only when a boat in a marina has shore power (120V) and a bad connection of the hot side into the water. This can only occur with shore power, because otherwise the circuit can’t leave to boat. It also doesn’t occur in salt water because salt conducts electricity better than the human body.

An EV battery might have enough voltage, but the current would prefer to travel directly from - to + on the battery itself. You would have to literally get in the way of that for it to affect your body. Most situations where that could happen, such as touching the electrodes directly, would be almost as dangerous even when you are dry. And again, salt water would conduct it much better than your body, therefore bypassing you, as long as you don’t get in the way.

USB PD (Power Delivery) actually does use a higher voltage for more wattage. Standard USB is limited to 5V at 0.5A and sometimes up to 5V @ 2A on quick chargers. But PD chargers can give 20V and 3A for 60w or even 5A (100w) with properly rated cables. There’s even a proposal for up to 48V at 5A to get 240w. This is all determined by a negotiation between the charger, the cable (which does have a small chip for this purpose), and the device, therefore PD chargers must support multiple voltages.

Sounds like sleep. Hibernate is when it turns completely off, such that you can leave it unplugged for a weekend and still have battery when it pops you back into your session. It takes longer to save and restore the session than sleep does.

I’d guess it’s easier for the paramedics to jump out when they first arrive on scene. Nothing happening in the back yet, so they can look around and see the situation while rolling in.
