I see. Tell me more about that's because we know Eliza's "trigger" questions that tip her hand.

Is this a news story or just an advertisement?

The Martian had excellent realistic science, but failed as a novel IMHO. Watley is stranded on Mars, utterly alone. Is he scared, depressed, angry? Does he blame the other astronauts? How does he cope with it all? Sorry, we're not going to talk about any of that: too busy turning hydrazine into potato fertilizer.

The Martian: definitely
Interstellar: I don't see this as an example of hard sci-fi at all. A bunch of gobbly-gook about a magic mathematical constant needed to overcome gravity and that was transmitted through some kind of hyper-dimensional dream fugue.

How about Neal Stephenson's Seveneves? Or Avogadro Corp by William Hertling?

Is this "Notify me when a restart is required" option available for home users, or only for Enterprise Edition group policy? I'm running the home version of Windows 10, and every couple of days I come to my PC in the morning to find that it restarted overnight. Some programs aren't shutdown cleanly, and it's a super pain in the ass. If there's any way to delay or control these restarts, or reduce their frequency, it would be a huge win.

This comment - you are writing, likely, than any sentence oddly, full of commas.

And what's the point of a loan if you need to repay it in the same instant that you borrowed?

I'm sympathetic for people who fall for Zelle scams, but I don't understand why anyone thinks the banks should replace their lost money. The banks didn't pull the scam, and they don't have the stolen money. If somebody tricks you into walking into a bank branch and withdrawing $1000 cash and giving it to them, would you expect the bank to reimburse you? This just seems like an example of victim mentality and believing that anyone but you is responsible for your problems.

Summary was apparently written by James T. Kirk.

Thanks. But I still don't see what the problem is here. The retail investor gets their trade at their limit price or better, and your company makes a few pennies on average by making a short-term bet about subsequent price movements. Why is that a problem?

It seems like the regulators' real beef isn't with paying for order flow, but with the basic idea of zero-commission trades, which payment for order flow helps make possible. Regulators dislike zero-commission trades because they make it "too easy" to trade stocks, and potentially fuel meme-stock rallies. Does that sound right?

I don't get it. What exactly is happening here that's viewed as a problem? Can someone who's familiar with this please explain in more detail?

Telnet seems to be installed on my Mac by default. Windows users can grab PuTTY.

Bitcoin is not encrypted, nor is it really anonymous. The blockchain is a type of public ledger. Anyone can look at it, and see how many coins are held by Bitcoin address 292397, and what addresses those coins came from. Anyone can watch the blockchain for updates, and know the instant when the owner of address 292397 spends some coins, and what addresses the coins are sent to. All of this transaction and balance information is available for everyone to see. That makes it very trackable.

Bitcoin is secure because nobody except the owner of address 292397 can create a valid transaction that spends coins from that address.

Bitcoin is somewhat anonymous, because in theory nobody knows that address 292397 is owned by John Doe of Pittsburgh. But in practice it's not that difficult to match addresses to real people, if you have lots of historical transaction data and other personal data from the real world that you can correlate with bitcoin transaction records.
