This chart shows all objects in the Universe, arranged by mass (vertical) and radius (horizontal).

The edge of the upper left corner is the "Schwarzschild radius" - anything along this edge becomes a black hole, so we don't expect stuff above and to the left of that.

The edge of the lower left corner is the "Compton wavelength" - anything here has a size so small that measuring its position that accurately would require enough energy to create a new one.

These two corners intersect in a white dot. This would be a black hole so small that it's heavily affected by quantum mechanics. By definition its mass would be the Planck mass, and its radius the Planck length. Nobody has seen such a thing.

The black region to the left of that dot, labeled "QG", contains imaginary objects that are more compressed than black holes, yet also ruled out by the uncertainty principle. So they're doubly impossible - unless Quantum Gravity, which we don't understand, changes the rules.

The pink strips of slope 3 are lines of constant density. For example "QGP" is the density of quark-gluon plasma, "BBN" is the density of the universe when Big Bang nucleosynthesis was going on, and so on.

The Earth is only slightly more dense than a flea.

The black dot labeled "Hubble radius" is the whole observable universe.

I like this chart a lot. It's from here:

@dangoodin it adds an additional confirmation (that sends pretty useful). It’s a proprietary extension
So for services that use that push MFA, I don’t think there’s a substitute

Backup on iOS uses iCloud, which stinks if you don’t have premium iCloud. I’d prefer a passkey

If you could tell your Congressional rep not to vote for a bill that would give the Trump administration the power to revoke non-profit status from any org they don't like...say...EFF, for example, I would appreciate it.

Tell Congress Not To Weaponize The Treasury Department Against Nonprofits

The House of Representatives just passed a dangerous bill that gives broad and easily abused new powers to the executive branch would allow the Secretary of Treasury to strip a U.S. nonprofit of its tax-exempt status. Nonprofits would not have a meaningful opportunity to defend themselves, and could be targeted without disclosing the reasons or evidence for the decision. Even if they are not targeted, the threat alone could chill the activities of some nonprofit organizations. Over 130 civil liberties, religious, reproductive health, immigrant rights, human rights, racial justice, LGBTQ+, environmental, and educational organizations signed a letter opposing the bill as written. We most tell the Senate not to pass H.R. 9495, the so-called “Stop Terror-Financing and Tax Penalties on American Hostages Act.”

@north maybe somewhere. I have a “land line”, but it’s over fiber instead of twisted pair copper. A long distance calling bundle is included in the package.
Somewhere, maybe there are a few people with classic hookups paying for long distance because they’ve been maintaining a contract since 1988.
I’d be surprised if ATT hadn’t simplifies the contracts and eliminated it, but I heard of someone still leasing a phone from them a few years ago

I never, ever respond to political text messages. It is impossible (for me, anyway) to know which ones are scams -- most of them, I suspect -- and which might be legit.

Even the "legit" texts are a plague of spam in any case.

I block and report as spam all political texts.

YMMV, but it looks from here like criminals have declared open season on our bank accounts.

Doh! It was Friday we flew out! That was the first day.

The next day, my son in college was flying out. He had a seat assigned. His aircraft had been parked at the airport the night before. Reportedly, the airport was less chaotic.

We found out about his flight delay about five minutes before he did. He was delayed about an hour.

Then, we found out about his flight cancellation about five or ten minutes before he did.

He had to get into a massive line to rebook. The mobile app offered to help him rebook his flight, but that kept erroring and not showing any alternative flights. I called him. At the time, I didn’t think this was the worst airline IT fiasco. Now, it looks like one of the worst, if not the worst—espresso for Delta.

The mobile app wasn’t effective. He couldn’t talk to their call center—hold times were hours. Texting didn’t work. He doesn’t have a Xitter account, and I don’t think that would have helped. Chat support was down.

I went to the website, and worked to rebook his Saturday flight. There was nothing for Saturday or Sunday. Other airlines, like Southwest, were sold out on Sunday.

The rebooking pages look like HTML from 1998. I rescheduled for Monday, and was redirected to the home page—it turns out, the seat was probably acquired by someone else, and there was no error message. I rescheduled again—same mystery behavior again. Finally, I got confirmation on a Tuesday flight. It was clear that this part of the operation hadn’t gotten attention in years.

My son got a ride from the airport with a friend

I’d never had to go this far down the website to do anything with Delta. We had a great trip—my son’s was shorter than planned—but a lot of less tech-savvy people who travel less probably ended up in worse shape
