Reply to comment by Arunia in ELI5: When a third party app says they offer "end to end encryption," what does that mean? by [deleted]
There are some who offer "end to end" encryption, but the app provider actually knows the encryption keys.
So while it is technically true that they have e2e encryption, they can read it anytime they want/need to.

For the Colosseum (Flavian Amphitheater) and many other structures it was because the buildings were no longer necessary, and the materials used in their construction could be better used elsewhere. Many cathedrals and other public works were created using the stones of ancient buildings. If you look closely at the Colosseum, you'll see thousands of little holes. These are from people who harvested the iron clamps the Romans used to hold bricks together.

What they're claiming is that your data gets encrypted on your phone and doesn't get decrypted until the intended recipient gets it. Encrypted data can't be read without decrypting it first, so in principle end-to-end encryption ought to keep the app developer from sitting in the middle of your conversation reading your messages.
In reality, though, it's important to remember that anyone can claim their app uses end-to-end encryption, whether or not it actually does. So you shouldn't rely on an app to do the right thing.

What is not "end-to-end" encryption is when the email is encrypted during transmission between servers, but is transferred from your email server to you in a form that the server (and its operators) can read.
And that's actually the usual case, as email headers must be readable by the servers because they have routing information, and some email servers will also scan your emails for spam, attacks, and viruses.

Because maintaining massive stone structures is expensive, and often nobody owns these buildings, and lacks the means to make the upkeep a paying proposition. When times are bad, and money scarce, people's romantic attachment to history very quickly goes by the board.

Standard messaging platforms resemble an old-school telegraph. End-to-end encryption more closely resembles physical mail.
To send a telegraph, you beep out your message. This gets sent to a telegraph station, where a person listening writes down your message, and then beeps it on to the next station down the line, where there's another person waiting. Eventually, someone writes down the message and hands it over to the recipient.
The important thing to note is that the telegraph operator reads the message at every hop. So if your telegraph operator knows your cousin, they'll gossip. And if the Government thinks you're up to Crimes, they'll watch over the shoulder of the telegraph operator to see if anything Looks Like Evidence.
Mail, on the other hand, is sealed in an envelope. And that envelope gets handed to a postman, tossed around by baggage handlers when it's put on a plane, carried around by another postman, and then delivered unopened to the recipient. No one else has seen the content of the envelope until the recipient opens it. It is a crime for anyone else to open this mail, even the Government if they're not going through proper channels (warrantee void where it's voided).
The encryption is, more-or-less, the envelope that stops non-recipients from reading. The "end-to-end" part is the fact that it stays unopened from the beginning of the journey to the conclusion.
This, of course, relies on trusting the postal system actually does what they say they do. The post office has actual laws that guarantee it works this way, whereas some service that claims end-to-end encryption does not.

Probably not actually, the only reason Rome survived the fall was because of the Church drew people there. Its population dwindled almost 90% and was sacked multiple times in-between the fall of the Western Empire and the Medieval period.
And even then the power of the city waxed and waned depending on who the Holy Roman Emperor was. The Holy See was moved for 70 years to France in the 14th Century
They always had other stuff to spend it on, like Armies, gifts and tributes to avoid attack, defenses, feeding the city, building new buildings with materials taken from those ruins. Keep a pagan building up to its prechristian status was not something anyone would want to spend money on.

Content is encrypted before it leaves your device, and is only decrypted when it reaches the other person's device. It has been encrypted from one end to the other.

The encryption is from your end to the other and only both devices know the code to decrypt the messages. Which means it should be safe.

GoodRx is specifically subject to a very recent FTC order requiring them to provide guarantees of data security and privacy. They have paid a fine for not doing so previously.
Whether you believe GoodRx will be more private/secure now that they have an explicit order and the eye of the FTC on them is up to you. Both "they fucked up once they'll do it again" and "they fucked up and now they'll have to clean up their act" are reasonable possible positions.

XI
But who, of all the plunders of yon fane On high, where Pallas linger'd, loth to flee The latest relic of her ancient reign; The last, the worst, dull spoiler, who was he? Blush, Caledonia! such thy son could be! England! I joy no child he was of thine: Thy free-born men should spare what once was free; Yet they could violate each saddening shrine, And bear these altars o'er the long-reluctant brine.
XII
But most the modern Pict's ignoble boast, To rive what Goth, and Turk, and Time hath spared: Cold as the crags upon his native coast, His mind as barren and his heart as hard, Is he whose head conceived, whose hand prepared, Aught to displace Athena's poor remains: Her sons too weak the sacred shrine to guard, Yet felt some portion of their mother's pains, And never knew, till then, the weight of Despot's chains.
XIII
What! shall it e'er be said by British tongue, Albion was happy in Athena's tears? Though in thy name the slaves her bosom wrung, Tell not the deed to blushing Europe's ears; The ocean queen, the free Britannia, bears The last poor plunder from a bleeding land: Yes, she, whose gen'rous aid her name endears, Tore down those remnants with a harpy's hand, Which envious Eld forbore, and tyrants left to stand.

Not always. Insoluble fiber won’t break down, and it’s common for whole seeds and fruit skins and other tougher materials to remain whole all the way to your poop.

Bullets fly in arches, they are pulled down by gravity. If you would fire a bullet horizontally over a flat surface and at the same time drop now from the same elevation it will hit the ground at the same time.
the result is the scope does not look parallel to the barrel, the barrel will point slightly upwards if you aim horizontally. It looks like https://qph.cf2.quoracdn.net/main-qimg-20f8f9b2aa7051df653d04e40e2233c2.webp The image uses rear and from irons sight, a scope will create a line of sight the same direction as an iron sight
You zero a sight so the bullet trajectory and the line of sight are at a specific distance. Sight for rifles usually have an adjustable rate setting that is calibrated for the rifles and ammunition so the line of sight is changing relative to the barrel the correct amount so they intersect at the new distance.
So if you zero the rifle with so, for example, the 100-meter setting hits the line of sight at 100 meters when you then change the setting to 200m the bullet should hit the line of sight too. If the range is incorrect the bullet will hit above or below where you are.
If you can hold a weapon vertically all the time the distance the optics are above the barrel does not matter for accuracy. If you need to turn the weapons sideways it is better if you have them closer to the barrel but that is something that is more likely you need to do with assault rifles than sniper rifles.
The main problem with a large offset is to avoid hitting something just in front of the barrel. If you are on the uneven ground something could be in front of the barrel but not in front of the sight. Lay down on the uneven ground and try to expose your body as little as possible to enemy fire then you risk just seeing over some dirt that is directly in front of the muzzle. This is the

What, no.
Thats doesn't make any sense. If we restored it to how it actually was, how is that a projection?
Also, nobody is suggesting we should do a full restoration, so again, what are you talking about?

I work for a doctor's office and we do have a significant patient population that benefits from GoodRx coupons.
I use the provider page to search their drugs and send the coupons via print to PDF and email them. It seems to be working just fine, though I am sure the data coming from my IP address must make me look like a pill fiend.
