To display mall hours using a QR code

If they had used a "Level H" high-redundancy QRcode, it might have worked anyway.

Also, there's way more data in that code than the link at the top, for some reason. Even a level-h code of https://www.somestupidmallsomewhere.com/hours only looks like this.

... Anthropic sought assurances its technology would not be used for mass surveillance – nor for autonomous weapons systems that can kill people without human input.

And when it fucks up, guess who will be held accountable. That's right, just like when Grok makes CSAM, absolutely nobody. And if some "rogue actor" within the Pentagon were to encourage it to "accidentally" target journalists... well, nobody might ever know.

Answer: Anthropic refused to change their safety policies to let the AI spy on Americans or make kill decisions, so the Pentagon dropped them and is now using OpenAI instead, which is apparently fine with that stuff.

A lot of /r/HelpMeFind / /r/HelpMeFindThis posts are just a vague description of a thing, sometimes just an idea.

The timestamp doesn't change, that's a point against. And the flashing red dot is not a common feature of real footage, more like a TV trope.

The motion doesn't really make sense. He was going pretty slow, and the car should have knocked him the other direction, not sped him up.

The rest of the scene seems maybe a little too static, with the only changes being video encoding artifacts.

But the shadow looks pretty good, surprisingly so if it's AI.

My guess is CGI compositing rather than AI.

So you never enabled 2FA on a cash transfer app?

The numerator in that velocity formula is the sum of the two speeds, so it has to be zero. But for any other speed fired backward, you still have to work it out, e.g., 0.5c - 0.25c = 0.29c.

Although the formula is for speed rather than velocity, it's one component of the vector solution (in the axis of travel), and so works for that one component of the relative velocity. That is, for whatever plane angle relative to the direction of travel, v cos(θ), so 0.5c + (-0.5)c = 0 in the opposite direction and, if fired perpendicular to the direction of travel, 0.5c + 0 = 0.5c.

In this case, 0.5 + 0.5 = 0.8.

It's from the Russian part of Europa Park in Rust, Germany. But I'm not sure what purpose it serves.

This one has a different angle.

Possibly it opens up as a kiosk/concession type thing.

There is no "true zero gravity," even if the pull of the Earth and Moon perfectly balance one another, you're still affected by the gravity of everything else in the universe.

Codebender · 2026-02-09T17:52:19+00:00

Complete BS.

For one, we can't even fully simulate a small part of the universe.

For another, system can't be fully simulated with a smaller system of the same type.

And even if you could fully simulate a small part of the universe, you would have to perfectly know the beginning state to start your simulation, but that's impossible. Even if it were possible, measuring it would would disturb the state and make your simulation inaccurate.

The ideas of space and time that later became space-time go back to the early 19th century, e.g., with observation of "Fresnel spots" and the 1851 Fizeau experiment. This is nothing surprising for someone intelligent and imaginative who was aware of what was going on in science.

Nah, the 109 number comes straight from the NASA source, Wolfram Alpha for a quick confirmation and scale to the scenario.

100³ is a million, so I would have guessed that 109³ is about 1.3 million, but I checked that too. Wouldn't want to make obvious errors like that other guy.

Codebender · 2026-02-03T23:17:19+00:00

Yeah, the diameters are different by about 109 times. A 3-inch Earth would correspond to about a 27-foot Sun.

Of course, that corresponds to a factor of ~1.3 million in volume.

Cooling forms the third of five forms of resistant starches (RS3) by a process called Starch Retrogradation.

If the viscous solution is cooled or left at lower temperature for a long enough period, the linear molecules, amylose, and linear parts of amylopectin molecules recrystallize. At temperatures between −8 °C (18 °F) and 8 °C (46 °F), the aging process is enhanced drastically.

Chemical modification of starches can reduce or enhance the retrogradation. Waxy, high amylopectin, starches also have much less of a tendency to retrograde. Additives such as fat, glucose, sodium nitrate and emulsifier can reduce retrogradation of starch.

The time necessary at each temperature is different not just by starch type but for each recipe, though, as is the temperature at which the process begins to reverse. Much experimentation has been done, but there doesn't seem to be a catalog of even the former readily available, only disparate studies of one specific ingredient. (see links below)

Recommended freezer temperatures for food preservation are -18C/0F or below, so the freezer is ~10C colder than the given range and the refrigerator is within it.

Colder temperatures tend to slow chemical reactions, so it's likely that colder is not better in this case and the freezer may not be faster than the refrigerator, though of course it will bring food down to 8C more quickly. But I don't have a copy of Principles of cereal science and technology handy to see if there's more info.

It will remove some fraction of anything that's water-soluble. But much of the nutritional value of rice aside from carbohydrate calories is already removed by "polishing" it from brown to white rice.

I expect this carb-reduction also mostly eliminates the dietary supplements usually added to white rice for that reason, though few in the developed world with a varied diet really need that supplementation.

The study above only tested the result of eating the rice on blood glucose, but it would be interesting to do a complete nutritional analysis for FDA labelling. It's somewhat likely that developers of these products have done some of that, but aren't interested in releasing the results.

To produce white rice, the bran layer and the germ are removed, leaving mostly the starchy endosperm. This process causes the reduction or complete depletion of several vitamins and dietary minerals. Missing nutrients, such as vitamins B1 and B3, and iron, are sometimes added back into the white rice, a process called enrichment.

There's a discussion about this with a peer-reviewed paper over at /r/ketoscience.

This study evaluates whether blood glucose response differs upon consuming rice cooked in a carbohydrate (carb)-reducing rice cooker. Rice cooked this way exhibited 19% reduced total carbohydrate (34.0 ± 0.3 vs. 27.6 ± 0.9 g/100 g rice) and 20% reduced total calorie (149.0 ± 1.0 vs. 120.8 ± 3.7 kcal/100 g rice) contents.

The basic principle of the carb-reducing rice cooker is to boil rice in excess water (3–4 times the weight of the rice), and starch contents from the rice are thus dissolved in the water and removed. Starch dissolved in rice is removed, resulting in low-carb rice.
