The toll castle of Pfalzgrafenstein once exploited a narrow stretch of the Rhine. Its rulers could lower chains across the river, stop passing ships and charge for access to a waterway they had done nothing to create. That arrangement is an old illustration of economic rent: income extracted by making a cheap or abundant resource artificially scarce.

Amazon Cargo Boeing 767 Crashes At Miami International Airport (r/news)

• firefaery: Hope the folks that were on that plane are okay
• DarkBomberX: If the photos are anything to go by, hopefully the crew is okay. Looks like the cockpit is intact.
• Grown-Ass-Weeb: 24FlightRadar is showing a lot of planes being diverted to Ft Lauderdale, Tampa, and Orlando. And some being routed to the Dominican Republic or returning to where they came from in South America. I’d hate to be the ATC workers right now.

US carrier Abraham Lincoln departs Thailand after respite visit (r/news)

• Meta2048: I know a couple people in Pattaya where they docked and they said there wasn’t a very noticable increase in tourists. They saw some small groups (3-5 people) of likely sailors wandering around but nothing crazy.
• southendgirl: After 250 days, they only got 5 days in port??? Couldn’t they get 10 days since their carrier just broke the record?
• Cmd3055: All these people taking pictures of the aircraft carrier somehow made me think of what it might have been like to watch the last Roman legions march by as they were leaving Britain.

What’s a common ingredient that completely ruins a dish for you, no matter how small the amount? (r/AskReddit)

• sailphish: Maybe not super common, but lavender. I’ve never had something with lavender that wouldn’t have been better without the lavender. I feel like they put it in deserts to be fancy, but the food just ends up smelling like laundry detergent.
• BrianKronberg: Shell. Sorry Maryland, getting shell in my crab cakes does not prove it’s real, it proves laziness in the kitchen.
• papasmurf303: Anything that touched a silicone utensil that’s been through the dishwasher. Apparently I’m one of the lucky few who has the receptors for it, and it makes anything taste like pure dish soap was added to it.

For the men with more life experience, what’s one lesson you learned the hard way that every young man should know? (r/AskReddit)

• Artofxian: People either like you or they don’t. You can’t make people like you the way you like them
• Specialist_Gas_8984: Meaningful male friendships get increasingly harder to make as you get older. Don’t take your existing ones for granted, invest in them, make time for each other, even as life gets increasingly busy and pulls you in different directions.
• Hogjocky62: Never respond to a major problem instantly. Think about it for hours or days and respond firmly with a steadfast plan. Never make large financial decisions based on emotion! Walk out of the negotiations at least twice before signing!

Are Microsoft titles severely inflated? (Blind)

• failmode (Microsoft): I was going to say the other way around. We import dipshits from places like Meta and give them a partner title (or higher) and they just don’t understand what it means to build a platform.
• Yaamraj (Microsoft): I jumped from L62 to E5 so meta isn’t any better wrt title inflation. I jumped back from E5 to L65 in 2 years and now am a L66. I will try for E7 and above now on It’s a funny game
• 他强让他强 (Microsoft): You wish. Partner is the new senior, principal is the new sde2. Yes, in many orgs, giving higher title is deliberate, in exchange for stagnated tc increase.

My wife hasn’t slept with me since she was laid off from Meta (Blind)

• minokotok: About 2-3 month layoff shock is normal. People differ - some instantly get into the maniac phase : grooming like crazy, interviewing, happy and energetic. Others feel down and absolutely devastated. Obviously, maniac version is more fun. All will pass.
• worstever (Microsoft): When my husband laid off last year, he was slowly losing his mind in the whirlwind of interviews and rejections. We actually started doing a thing we called “Small Town Saturdays” where we would go to a new small town we hadn’t been to before, grab breakfast at a local diner, and then roam whatever thrift stores, antique stores, and book stores we could find. Basically, we found that getting him out of the house and routine of constant interviews and rejections for at least 1 day a week was KEY. But he also opened up more about what he was feeling during those trips, which helped us connect better emotionally.

The usual way to improve a coding agent is to give every task a stronger model. That raises quality, but it also spends frontier-model compute on routine work and still leaves the model without an independent reviewer when the task would benefit from one. Project HydraFusion takes a systems approach instead: decide at runtime not only which model should work, but which small workflow of models is worth paying for.

A forecast built from one number

Most predictions of human extinction begin with a threat: nuclear war, an asteroid, ecological collapse or some other physical mechanism. The “doomsday argument” begins somewhere stranger. It uses probability and a single estimate—that about 117 billion humans have been born—to suggest that humanity may be much nearer the end of its history than the beginning.

Techmeme surfaced OpenAI’s September 6 report, “Research acceleration: The view inside OpenAI.” The company says it has reached an “automated research intern” milestone: its coding agents can now carry out some well-defined research tasks that would take a skilled person several days, provided a human chooses the task and supervises the work.

The familiar warning that the stock market is not the real economy now has a second layer: benchmark indices are no longer good portraits of the stock markets they supposedly represent. A handful of enormous companies, many tied to the artificial-intelligence investment boom, increasingly determine the movements of indices containing hundreds or thousands of stocks. The result is that diversified-looking portfolios can carry far more concentrated and volatile risks than their labels suggest.

Constitution doesn’t include right to clean water, federal court rules (r/news)

• Grey-Squirrel-World: That is why they passed the Clean Water Act in 1972.
• wallyrules75: Because when the laws were written no one thought we would be sooo stupid to ruin our water sources. So this judge sides with stupidity that benefits the few over the welfare of the masses.

What’s the worst carcinogen most of us are unknowingly inhaling or ingesting every single day? (r/AskReddit)

• yoc0__0: It’s 100% radon gas, and nobody talks about it. It’s the 2nd leading cause of lung cancer and primary cause for non-smokers. I discovered we had a radon issue in my new house when I moved in. Was the equivalent of smoking a pack of cigarettes a day just breathing the air in the basement, half a pack upstairs, and the issue wasn’t even as bad as a lot of people’s radon levels. It’s terrible for you and it depends on where you live geographically with how bad it is, but damn near everyone should get radon mitigation.
• GuyWalksOutOfABar: From all the responses, apparently it is breathing, eating, and touching.
• Gerble66: We’re learning a lot right now about how harmful tires are. When they wear down, they spread micro plastic debris and other materials which are harmful to basically all life.

You’re dropped into a medieval battle in a tank with giant speakers — what song do you blast to terrify an army that’s never heard recorded sound? (r/AskReddit)

• MrOxion: Any Mick Gordon song from the Doom soundtracks (especially “the only thing they fear is you”)
• ShufflingToGlory: Probably some haunting contemporary hymn, sung by a large choir. You’d want them to think God’s judgement had arrived to take them to hell.
• TenaciousLilMonkey: THX sound effect

What did you think was an American stereotype until you actually visited? (r/AskReddit)

• kinetic_honda: That Americans are very friendly. I have lived in the US now for 19 years and I can happily say that this is very true. As a brown immigrant, overwhelmingly, I have been treated very well here and people have always been very friendly.
• maxpoontang: My nephew came over from Germany and was shocked the buses were actually yellow. He enjoyed the American experience though.
• Kloppite16: Not so much of a stereotype but more so an effect. Growing up as a kid (not in US) I watched movies shot in New York and there would be steam coming out of the manholes in the street in dark scenes, think Batman. I always thought that the steam was a movie effect till I visited New York last January and the steam coming out of the manholes is definitely real. My jaw kinda dropped at seeing it and then I felt like an idiot.

Quick facts

• Difficulty: MEDIUM
• Problem: Delete Node in a BST
• Topics: Tree, Binary Search Tree, Binary Tree

Problem gist

Given a binary search tree and a key, remove the node whose value equals the key and return the tree’s root. If the key is absent, the tree should remain unchanged. Every value is unique, so the binary-search-tree ordering identifies at most one node to delete.
