P.S. Even though itÃ(TM)s not my thing, I bet FacebookÃ(TM)s software can handle iPad apostrophes. Hey Slashdot, perhaps you should ping them for technical advice? Then again, I donÃ(TM)t mean to rush you. ItÃ(TM)s only 2021. WeÃ(TM)ve only had web boards for about 30 years. These things take time IÃ(TM)m sure.
Ever consider that maybe the problem is that the iPad apparently can't produce standard ASCII apostrophes? 99% of the posts here have no problem with apostrophes, only those that are "Sent from my iPhone".

And in the meantime, his bitcoins may now be worth $100 million. After his restitution and prison term, the remaining $91.7 million will go quite far in Ukraine.

Rupert Murdoch now owns the National Geographic Magazine and TV show. I think there is still a non-profit arm that pays for explorations etc. (which provides the material for the magazine and TV show, presumably benefiting Murdoch). Even so, people who donated large sums of money and even their estates before the takeover are probably are probably not too happy (or are spinning in their graves).

My guess is that they have bought into Ayn Rand's rhetoric (sounds like a paraphrase of the John Galt speech in Atlas Shrugged).

Isn't making false reports to the police against the law?

Attached to: iRobot Says It'll Be a Few Weeks Until It Can Clean Up Its Latest Roomba Software Update Mess
Exercise: If a house is 2000ft large, and a roomba is 1ft large, how many times does the house need to be cleaned with a random walk till every sq ft has been cleaned?
Model the house as a circle with 2000 sq ft area. Its radius is thus about 25.23 feet.
A 2D random walk with 1 sq ft steps takes about
(4/pi)*n^2*(log n)^2 steps to cover the room with radius n ft,
or about 8447 steps when n=25.23. So it is about 8447/2000 = 4.2 times
less efficient than doing the whole room without repeating a spot.

Attached to: Iron Powder Passes First Industrial Test As Renewable, Carbon Dioxide-Free Fuel
Those hand warmers that fit into your mittens use the same principle, turning iron into rust, with additional ingredients to slow down the reaction so it will last ~10 hrs. I use them all the time in the winter because I have Reynaud syndrome and as a result am susceptible to chilblains (bad blisters that last for weeks).
Occasionally the packs don't work, maybe because the packaging developed a leak or something. It turns out that a magnet will attract the good ones (with iron) but not the bad ones (with rust). Fortunately bad ones are rare; I think I've seen only a couple over several years that were not past the expiry date. But a magnet lets you avoid an unpleasant surprise outdoors, as well as letting you know if ones that have expired are still good.

Attached to: Zeptoseconds! Scientists Measure the Shortest Unit of Time Ever
Well, the Higgs boson lifetime is said to be
156 yoctoseconds = 0.156 zeptoseconds, which is over
1000 times shorter than 247 zeptoseconds. I wonder how
they measured that. With 3 digit resolution, to boot.

Attached to: Teenager on TiKTok Resurrects an Essential Question: What is Math?
There is also formalism, which is starting from a set of axioms and rules, and seeing what evolves. The starting axioms and rules that most mathematics can be derived from is first-order logic and ZFC set theory. Whether or not you believe the axioms isn't even relevant; it's just a game of mechanically manipulating the symbols in the axioms according to a set of rules.
Mathematicians don't work this way because it's much too inefficient. But just knowing the actual rules and how to start from them can be enlightening in itself, especially for people who sort of understand math intuitively but feel vaguely uncomfortable that they don't "really" understand it. Here is a comment from a high-school student who "discovered" formalism https://groups.google.com/g/metamath/c/CEhsDt9i6Zw/m/ITqazdzHBAAJ:
Metamath [a system based on formalism] was what I needed to overcome the discomfort that I had
with mathematics as I had been taught: intuitively grasping the concepts
while lacking any understanding of the underlying logic.

Attached to: The Gateway PC Brand Returns With New Laptops
My Gateway (in the late '90s I think) was beloved for one reason: it had a physical volume control wheel, mounted on the side like in old transistor radios. I used it all the time, for instantly turning down some obnoxious blaring site and instantly muting it when I saw the boss approaching.
I hated the lack of it on my next PC that required multiple two-key-combination presses to turn the volume down, with a lag in the response. I was very close to modding it with an external potentiometer in series with the speaker but didn't quite get that far.

Attached to: Airbnb Criticized For Asking Its Customers To Donate to Their Past Hosts
Earn over $2million? 90% over $2 million. I'd even say the first $100,000 is tax free - that's right, a standard deduction of a $100,000.
A problem with this is that the people who most easily afford to pay i.e. have already accumulated a vast wealth can end up paying nothing, like Zuck who (I've read) pays himself a $1/year salary.
What I think would be better is an asset or "wealth" tax of some kind. This isn't a new idea; middle-class homeowners already pay a "wealth tax" i.e. a percentage of their home value as real estate tax.
Indeed, I think it would be interesting to explore abandoning income tax all together and base all federal tax on net assets (assets minus outstanding loans on them). BTW it wouldn't necessarily mean that the asset (like a farm) would need to be sold to raise the tax money. Instead it could be owed to the gov't, possibly as a percent of the asset rather than a fixed dollar amount, that would be collected when the asset is sold. There would be many such details to be worked out of course. But it has worked for real estate ownership (which is worse because the tax is based on full value, not net value after mortgage).

What does this have to do with liberal/conservative? Just because some wacko may be liberal doesn't mean all liberals are wackos. And whatever misguided point she's trying to make, I doubt she actually believes 2+2 != 4 when it comes to adding up the numbers on her grocery store bill.
I'd say someone Trump's illogical rants about COVID-19 (such as less testing means there will be fewer cases) and other things are far more dangerous.
