Yep, that right here is the kind of pattern-matching you have to be careful about! Read what you wrote carefully:

cooling effect ... temperature gradient

The vat is literally cooler. You put a thermometer in it, will show a lower temperature than thermometer in air. This is not a fake effect "only shows lower because it's wet", it's a real temperature. You put your stirling engine cool coil in the vat and hot coil in the air, you got yourself a temperature gradient. A small one, maybe 10 degrees C, but more than zero.

The people saying Maxwell's demon/"cannot separate" are mistaken. They've pattern-matched to the wrong concept. This is possible and is the way swamp coolers operate. They exploit the difference between ambient temperature and dew temperature of the liquid, say water. As long as relative humidity is below 100%, some water will evaporate, leaving your vat colder than environment. The separation is simple - the wind carries away the 100% humid water vapors, replacing it with fresh low-humidity air. You can then use the temperature difference to drive a stirling engine or something.

The point where your free energy ends is when you run out of water. You need to take your 100% humid air and cool it down somewhere else to get the water back by condensing it. In nature this happens automatically at nighttime when the heat radiates into the cold of space and air temperatures drop. If you are running a closed-loop cycle though, like on a spaceship, you need to provide your own source of environmental heat (the Sun) and your own heat sink (the cold of space), and at that point you should just be using a regular high-efficiency heat engine instead of this swamp cooler.

Don't like how the headline says "plummets", which implies an uncontrolled fall. The correct terminology here is "dives". They took "plummet" from the quote of a passenger, to whom the experience was indeed like random drop, but in the headline they use active voice with intent ("to avoid a potential collision"), which is the perspective of the pilot, so active control terminology should be used.

What you smoking? No one in New York is ever charged with vehicular manslaughter. It's all an "accident".You can even flee the scene like happened here, and if you are found you will still not be charged (leaving the scene of an accident involving injury or death is a crime but never enforced for some reason, a small traffic fine at worst). Just look, if they ever find this driver, all they'll do is ask some questions and let them go. You can even drive drunk, kill someone with the car, flee the scene, evade capture for days, and then maybe you'll be charged, but the charges will be dismissed anyway because now days later you being drunk cannot be definitely proven.

It's got all the details right - the twin engines, the glass front dome, the tricycle gear, the tail turret. Post this on Warthunder forums and you got a credible secret leak. Sure it looks like a scribble, but you try to draw a random plane from memory any better!

It's a future hologram that looks correct when seen from any direction.

There is a crazy idea that since Peano arithmetic has not been proven to be consistent (and cannot be proven so, by Goedel's Theorem), if you ever find a counterexample you can use nondisjunctions like these to immediately effectively prove anything. This may have dubious effects on objective reality. "I have one apple and one apple. Since I can prove that 1+1=5, I now have 5 apples." And boom! You got 5 apples.

Open up developer console (F12) network tab and reload page/play audio. In the list of network requests, look for something that looks like the resource you want (e.g. in this case, filename: "mp3", initiator: "media", type: "mpeg"), right-click and "save response as". This doesn't work on every site, but works on yours!

Fancier sites do not serve media files directly but fetch encoded chunks of data and recombine them using javascript. To get the whole file back you need to re-implement the javascript, which is what yt-dlp does, but only works for sites it knows how to handle.

I have conflicted opinions on this. Disrespecting a person's tragic death is wrong, but consider also if someone is so desperate for a stuffed toy that they would lift it off a memorial then maybe they really do need it hard enough to deserve it. The toy would just lie around in the rain otherwise and eventually go to waste. It's better use for the toy and better respect for the memory of the deceased if the toy ends up in the hands of a child of the desperate parent. Even if the thief has no children and is just crazy, wanting the toy for themselves, even a madman's comfort from having a toy has value.

The only situation where I can wholly condemn the thief is if they are taking the toys and flowers with intention to resell later. That's no better than digging up flowers from someone's yard!

Pedestrians are much more terrified of bicycles than cars, makes sense to put the guardrail there to protect them from vicious cyclists.

Oh right, the Nazis will come for the 2020 Census data next.

It’s unthinkable that CMS would violate the trust of Medicaid enrollees in this way

Once again stolen medical records are being used for state oppression. In WWII, the Netherlands suffered 75% of their Jewish population killed - the highest of any country even Germany - because the invading Nazis made a beeline for the medical records archive where the government kept a meticulous track of all Dutch citizens. I never volunteer race or ethnicity on any such forms - there is no medical benefit, it can only come back to hurt you.
