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.

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.

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.

Because bits are not expensive anymore, and if we used 64 bits, we might run out faster than the time needed to convert to a new standard. (After all, IPv4 is still around 26 years after IPv6 was drafted.) Also see the other notes about how networks get segmented in non-optimal ways. It’s a good thing to not have to worry about address space when designing your network.

SQL

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.

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.

They are cancelling flights because those specific airports don’t have the equipment to provide a precision landing (ILS) during low visibility weather. They only published a landing procedure with GPS. They will now spend a few months installing the ILS system to enable such landings so they can resume commercial flights.

Before GPS, all airports would be either VFR only or would have an ILS system installed. Since then, some airports were built without an expensive ILS but used a published GPS approach to allow low-vis landings.

They could have continued flights with only VFR navigation, but that would seriously restrict the weather they could operate in.

Or there was documentation. You even remember reading it.(Or writing it) But since then we’ve changed from shared folders to SharePoint to something else, and reorganized folder hierarchy at least five times. I have no idea where to find it, or if it was purged in one of the cleanups.

The guy that invented time zones was solving a problem where each little town had their own time standard. I don’t think that was sustainable.

My bank has called me a few times. Each time they ask about specific transactions, so it’s mostly yes/no answers. (Occasionally I’ve asked for additional clarifying info, but they never asked about card numbers or the like.) Usually it’s been abnormal transactions that i know about, but a few times it was a cloned card number being used elsewhere, (before chip became standard) and then I had the card shut down.
