The Pragmatic Engineer surfaced this piece in Gergely Orosz’s June 23, 2026 essay, Slow down to speed up: so much has changed in 6 months’ time. Based on his Craft Conference keynote and reporting across AI labs, large technology companies, startups, and traditional enterprises, the article argues that software development has crossed an important threshold: coding agents can now generate changes faster than many teams can review, understand, and safely absorb them.

Montreal mayor says husband, who is Black, was stopped by police last year ‘at least 5 or 6 times — for nothing’ (r/news)

• dra_cula: I’ve heard that is called “driving while black”
• hearmeout29: My friend purchased a really nice BMW and he would get stopped a lot after he bought it. He always said cops would ask if any drugs were in the car and what he did for work when he was stopped. I’m guessing they thought he was doing illegal activities to get such a nice car. It’s fucked up.
• paulsteinway: Sometimes I ask white people in Montreal if they’ve every been pulled over for a “routine check”. None of them ever heard of such a thing.

Man falls to his death during rock concert at Madison Square Garden (r/news)

• Entire-Click2280: Goose are a band from Connecticut, Geese are a band from Brooklyn. Just pointing out the difference for people who were confused like I was.
• mountaindoom: Some arenas are just ridiculously steep in the upper levels. Prudential Center in Jersey scared tf out of me when I saw NIN there. Couldn’t even get up from my seat during the show, unless moving, and they were serving alcohol to us to boot.
• rgrossi: Was at the show.. terrible 😞

What popular career is actually not worth pursuing anymore? (r/AskReddit)

• GanonTechnology: Air traffic control. Pay hasn’t kept up, hours and stress increasing past sustainability.
• Adventurous_Bad_3421: Veterinarian. Roughly 250k for vet school, so huge student loans (and this is after a 4 year degree). You cannot make enough to pay them off unless you work for corporate (and even then…). Now you’ve got a high salary need coupled with corporate greed which equals high cost to pet owners who then resent you for it. It’s a no win situation. I’m not sure what the answer is, but lowering the cost of vet school would help immensely.
• CapnAwesme: Probably journalism, which is a real shame. We already have WAY more wanna-be journalists than the world can sustain which is why we have things like TMZ and so, so many clickbait sites.

What is a ’luxury’ item that is actually a total nightmare to own? (r/AskReddit)

• stool2stash: A few years ago we wanted to have a jacuzzi installed in our basement. The plumber who came over to give us an estimate actually talked us out of it. He said they are one of the most unused things people ever put in their homes and if you don’t maintain them to keep the pipes and jets clean, or if you just don’t use them often enough, mold can start to grow inside and then you spend half a day trying to clean the system. He recommended a big bathtub so we could just have a nice hot bath. We decided we didn’t have enough money for either option so hot showers are our spa experience.
• Prestigious_Cook_174: A massive house. It sounds amazing until you’re the one who needs to maintain and clean your 5 bedroom, 4 bathroom, double story with an open plan. Then realizing that you spend most of your time in the same three rooms anyway.
• JRS_Viking: A castle, you can buy them in plenty of places (especially in Europe) and they’re usually fairly cheap up front for the size of the properties and buildings on them. The problem is the upkeep, which you’re often legally obligated to do and obligated to keep it in it’s original state. So no big renovations, no changing the floor plan, no new shed in the yard for tools and equipment, no new stuff at all if it changes the historic value of the property.

Women in your 50s, what’s the most important piece of advice you would give to women in their 30s? (r/AskReddit)

• maudb: Sunscreen, wide-brimmed hats, no v-neck t-shirts in the sun, save and invest, appreciate and take care of your still-youthful body, cherish good friends, and try not to waste time worrying. The last one is my biggest regret, that I wasted so much time worrying and it accomplished nothing but making me miserable and stressed. (I finally wised up and mostly stopped.) Eeek, sorry, that was more than one piece of advice. Ok then, don’t worry so much is my #1.
• beach-drinking-247: Don’t worry about what other people think of you. They are more worried about themselves than anything you said or did.
• EveningAstronomer495: Please floss. Floss, I’m begging you. Every single day. I am the Ghost of Dentist Visits Future and I’m here to tell you what your bills are gonna be like if you don’t.

Being looked down upon as Amazon employee (Blind)

• horn dog (Meta): H1Bs and their obsession with prestige 🙄

• Big Cack (Amazon): You’re hanging out with the wrong people son

Grad to staff in 2 years at meta (Blind)

• CapybaraBK (Booking.com): They are a complete liar, not rare for people that turn into founders to lie about their background.
• bo34fi86fi (Meta): Not really. On average meta e3 to e4 takes a year, then e4 to e5 around 2 years. e5 is only senior. Staff is e6. To get to e6 there needs to be enough scope/business reason for the manager to justify it., and it takes years usually. Also the promotion is lagging so you essentially need to be performing at an e6 level for around a year before you get promoted.
• cv-x (Mercedes-Benz AG): No, but you can get from Staff to unemployment in 2 years

Americans Have Turned Against AI in Incredible Numbers (r/technology)

• UnderstandingLess156: Meanwhile at work, “have you tried using AI to write your emails?”
• Arcosim: I’m a very tech oriented person and I’m already tired of AI because it’s constantly being shoved and pushed down my throat by some of the worst human beings imaginable wanting to maximize profits at the expense of humanity itself.
• Asyncrosaurus: Who knew having every CEO come out and scream about how their cool new AI product was going to cause mass unemployment, would result in backlash. No way to have forseen that.

Polymarket Accused of Using Fake Winning Bets to Fuel Viral Growth (r/technology)

76-year-old woman killed after a Tesla ‘on auto-pilot’ crashed into her Texas home (r/technology)

• Ruddertail: Jeez, how fast was it going to punch a hole like that? That’s crazy unless they build houses out of paper in Texas.
• orangeyougladiator: Cue Elon bots coming to tell us why this wasn’t the Tesla fault
• sysadminbj: I’d be very curious to learn what the onboard sensors have to say about this. Was the driver paying attention? Were they asleep? Is this just a freak thing where the autopilot software got confused and freaked out?

One Fluid, Three Scales

Fluid physics works because scientists can describe the same liquid or gas at radically different levels. At the microscopic scale, Newton’s laws track particles as they move and collide. At the mesoscopic scale, the Boltzmann equation replaces that impossible particle-by-particle accounting with the statistical behavior of a typical particle. At the macroscopic scale, the Euler and Navier-Stokes equations treat the fluid as a continuous substance, allowing engineers and scientists to model everything from airflow over a wing to weather systems.

Techmeme surfaced Lily Hay Newman’s WIRED report, “OpenAI Launches Full-Scale Effort to Patch Open-Source Bugs as It Takes on Anthropic’s Mythos”, published June 22. The story captures a practical shift in AI security: frontier models are making vulnerability discovery cheap enough that finding bugs is no longer necessarily the hardest part. The new constraint is the human and organizational work required to validate reports, decide what matters, write acceptable fixes, test them, and coordinate disclosure.

This summary covers The Economist’s June 13th, 2026 Science & technology column listed in the contents as Well Informed: Anti-ageing balms and published under the headline The chemicals that reduce wrinkles.

The crowded market for anti-ageing skin products borrows heavily from biochemistry, advertising ingredients such as retinoids, antioxidants, peptides and exfoliating acids. Much of the supporting evidence, however, comes from company-funded studies or consumer surveys. Only a smaller group of ingredients has convincing scientific backing, and even those can reduce some visible signs of ageing rather than stop the process.

Lebanese turtle conservationist Mona Khalil killed by Israeli strike (r/news)

• invasiveplant: Poor woman. Sounds like she was a real source of straight-up uncomplicated good in the world
• 526mb: It’s sucks that decades of conservation efforts in one of the toughest places to be a conservationist may be overshadowed by the tragic circumstances of Khalil’s death. What an incredible legacy to leave behind.
• amy-schumer-tampon: They are speed running international hatred.

After deadly protests, more Iranian women choosing to defy hijab law despite the dangers (r/news)

• LameAfro: Imagine getting triggered over Womens hair. Biggest cry baby Goverment of all time 😂
• PlankownerCVN75: Fucking good for them, man.
• mynameisnotnemo: I want yall to understand that Iranian women have very thick skin and they don’t give a flying fu** about this law. My mom’s friend is a teacher in Shiraz and she goes to work without her roosari (hijab) and no one cares. Even the police around her in the school don’t press. I was just in Shiraz late last year and there’s a famous walking trail called piyadeh ra salamat. I walked here often and I saw women both with or without hijab and nothong was abnormal about this. It feels like a law which is still the written “law” but it’s not being enforced how outsiders may think at all. If the government attempts to crack down on those opposing this law, it will fail.

Kentucky Attorney General sues prediction market, online casino companies (r/news)

• TheKingPooPoo: Someone must not be getting their slice of the pie
• Not_a_Rodeo_Clown: My guess is I don’t agree with this guy on pretty much anything, and I would not be surprised if his motive here is purely financial, but I will still applaud anyone taking on prediction markets.
• ImTooSaxy: We’re making a nation of gambling addicts, starting with kids buying “mystery box” toys as well as in video games. It used to be that you could only gamble in Las Vegas and Atlantic City, and maybe at the bingo hall at church. America has gotten real weird, real quick.

Pharmacists of Reddit - what recent medication trends are worrying you that aren’t being talked about? (r/AskReddit)

• Empty_Ad4954: I work in a large teaching hospital. We see lots of patients on GLP-1s with pancreatitis or recurrent bilious emesis. When they’re discharged they’re told to speak to the original prescriber about whether or not to continue the GLP-1. Which of course does not happen every time
• iamellenphant: Absolutely the GLP-1s. These are serious medications with potential for serious side effects (as another commenter pointed out with pancreatitis, I’ve also seen gastroparesis requiring surgical involvement). The fact there’s now so many of these unvetted companies willing to prescribe the plethora that’s out there with minimal supervision makes my skin crawl.
• AMH1028: Hi, actual pharmacist. I am worried about the vast number of over the counter ”natural supplements” that actually contain unregulated prescription medication. For example, gas station “stamina” pills that have sildenafil, a med that requires a prescription. Even stimulants are found in these supplements it’s crazy.

What’s so expensive that it’s not even fun anymore? (r/AskReddit)

• jillyymariee: Movie theaters. What do you mean a popcorn is more than my already expensive movie ticket?

Amazon VP argues humans are too inconsistent to oversee AI agents (Blind)

• ShitFarce (Salesforce): First humans were needed in the loop because they feared the backlash. Now its too much of a risk because fuck humans. I bet that VP can be easily replaced by an agent
• 小熊维尼 (Palo Alto Networks): Of course a dumbass at Amazon would say this
• XpBs23 (Meta): Leaders think they have intuition to make the right decision, 95% of the time it’s just luck

• DoesntWork (Justworks): Some place where I can’t be taxed. Some place where the US has 0 control. I think the Strait of Hormuz would be excellent.
• geffler (Microsoft): Everyone seems to talk about expat and moving to SE Asia but reality is everyone stays in USA
• hyX774J (Google): Taiwan and Andorra are the only countries with same-sex marriage and no extradition treaty with the US

Morale is so bad at Mark Zuckerberg’s Meta even the company’s own CTO admits it’s ‘probably the worst it’s ever been’ (r/technology)

• Prudent_Link6029: Virtual pizza in the metaverse should boost morale
• casualfrog68: The firings will continue until the morale improves.
• hmmm_: Every company I’ve ever been at, once employees feel they are disposable it’s over. You don’t easily recover. It corrodes individual performance, it gets team fighting each other, good people start to leave. It’s an insidious change in the way a company feels and the negative effect accumulates over time - usually CEO/CFOs have the good sense to move on so the new CEO gets blamed for the decrease in company performance.

Ukraine launches TrophyLab platform to share captured Russian weapons’ technology with allies — “Every missile, drone, and vehicle seized on the battlefield is now a source of knowledge for the free world” (r/technology)

• LifeFeckinBrilliant: Any Chinese or Iranian stuff I wonder…
• NeonFraction: They’re about to make some military nerds VERY happy.
• Puzzled-Hedgehog4984: The reverse-engineering pipeline has been running since 2022 — this just makes the output shareable at scale. What’s underrated here isn’t the captured hardware, it’s the institutional knowledge Ukraine is building about exactly where Russian supply chain quality breaks down. That catalog has value well beyond this war.

Problem gist

The input is a reference to one node in a connected, undirected graph. Each node stores a value and a list of neighboring nodes. The goal is to return a deep copy of the entire graph: every original node must have a newly created counterpart, and every edge must connect the corresponding copied nodes.

A Clock inside the Nucleus

Modern atomic clocks are already astonishingly stable: the best lose only about one second every 100 million years. Yet they still rely on electrons in an atom’s outer regions, where stray electric and magnetic fields can disturb the measurement. Physicists have long wanted to move the clock’s reference point into the much smaller, denser, and better-shielded atomic nucleus.
