There a whole branch of quantum mechanics research that’s trying increasingly complicated ways of not looking at the particles while trying to sneak a look.

Blacktip Reef sharks, like some others such as great white and hammerhead, are “obligate ram ventilators” because forward movement is the only way they can push water over their gills. Nurse sharks and some others are able to close their mouth and pump water to the gills while stationary.

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.

This is because NSA has two roles: eavesdropping on foreign adversaries, and protecting our internal systems from adversaries. Under the first role, they might introduce an exploit known only to themselves. Under the second, they help protect US systems from exploits known to others.

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 because ducks are actually going someplace, while eagles are soaring over a thermal, trying to stay in one spot to watch for food.

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.)

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.

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.

I’m not sure there is any more the hermit kingdom can be sanctioned, other than getting Russia and China to actually honor the existing sanctions. (Ha!)

Ukraine doesn’t want to target Moscow. They are not like Russia, they go after actual military targets, not civilians. They have been using their homebuilt drones for long enough inside Russia to show their priorities.

I can run 7B models on my laptop with its embedded GPU. Running on a phone or a Pi is possible with smaller models, but very slow. Expect good speed with a desktop Nvidea GPU. Later this year, there should be new computers with an NPU integrated to the CPU which should speed up computers that don’t have a dedicated GPU. (But a GPU will still outperform them by a lot.)

70B models will run very slowly on even the best consumer hardware due to memory limitations.

The whole point of a public key is it can be publicized. Use any public publishing method, the more public the better.

We knew the deal was changed, but not by who. (As far as I know.)

Hair is hair. At least they didn’t use wall paint.

Nearly all such satellites would have highly directional antennas, so the aliens would have to be neat earth before they could do that. Voyager is not expecting a command signal from anywhere else but Earth. The signal would have to originate not more than a fraction of a degree from Earth from Voyager’s perspective.

And now here in California, they are starting “Transitional Kindergarten” or TK for the 4 year olds, before they go to Kindergarten at five. (More focus on reading and writing than a typical Preschool.) TK is offered at the normal public schools, and at most private schools that have K and up.

Prions wouldn’t work like that. They would have to be very similar, and the same chirality, as our own proteins, or else the misfold would not self-replicate like prion diseases do.
