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.

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.

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.

But Recall is recording screenshots, not data stored on disk. That’s not the same as Apple’s hourly data snapshot which is just a automated backup of what you have already stored. Recall will be recording the videos or images you watch, even when you don’t keep them locally. It will store the things you decided not to save, and every time you have to open your password manager to check a password, or create a new one. It might be limited to your account, but that still means it’s accessible to anyone who can figure out your password or access your unlocked PC behind your back. Or to that virus you accidentally downloaded, if it’s not immediately detected.

I do a lot of code. That means I often deal with three or four programs at the same time, and perhaps 10 loaded throughout the day and I want to see them all. So I have two monitors that are each 27" and 4k.

This means I can see a web browser sized to a full 1080 size, next to a database query, and still see the code that I’m working on, and keep an eye on any new emails or text chats. Without needing to Alt-tab to switch windows. It’s like spreading your work over a dining room table, instead of those little desks you got in high school.

Most apps don’t need to be larger than 1080. But some can be taller to see more code (maybe 160 lines, for example) without scrolling too much. And I hardly ever deal with just one window at a time.

Some of that may not be subjective, even if it is a personal difference. Some need glasses, some don’t get glasses because they just barely need them, and others have problems glasses can’t fix, especially as we age. Some eyes are just different, and that’s physical differences, not just a difference of preference.

The problem is “unsafe websites” is actually a very broad category. Even popular, reputable websites have accidentally hosted malware in the advertisements, some of which can infect without a click.
