This summary covers The Economist’s April 25th, 2026 International article listed in the contents as America's arms industry and published under the headline Shooting to prominence.

The article argues that America’s defence industry is entering a disruptive phase. The Pentagon still relies on giant contractors such as Lockheed Martin, RTX and Northrop Grumman, but war is changing faster than their procurement habits. Cheap drones, software-defined weapons and battlefield AI are making older, costlier systems look ill-suited to some of the conflicts the United States is now fighting or preparing for.

CNN founder Ted Turner, a pioneer of cable TV news, dies at 87 (r/news)

• WREPGB: He’s been alive this whole time?
• hybridaaroncarroll: One thing I’m grateful for what he accomplished: TCM. Saving many old movies from the dustbin of celluloid history was a massive win for nerds like me.
• RipErRiley: The guy just dipped his feet into pro wrastlin and dethroned Vince McMahon temporarily. Impressive. Cable news? Meh.

South Korean judge who hiked ex-first lady’s jail sentence found dead just 8 days after sentencing (r/worldnews)

• HarlequinKOTF: Not suspicious at all.
• TheoreticalResearch: Creepy ass woman, creepy ass family.
• Grimtongues: Shin Jong-oh beat himself to death, dumped his body into a flower bed outside the courthouse, and then wrote a suicide note saying he was leaving this world voluntarily… seems legit

Alleged suicide note written by Jeffrey Epstein unsealed by federal judge (r/news)

• ScottScanlon: And this thing just magically appears six years later. Totally believable.
• mrdominoe: Was it written on some bullets?
• sirdodger: They unsealed that pretty quickly after they found it. Funny that the rest of the files are going to remain sealed and redacted until it’s been so long that their provenance becomes in doubt and any witnesses and corroborating evidence are long gone.

What scientific discovery sounds fake but is 100% real and still freaks you out? (r/AskReddit)

• Critical_Physics_770: Prions
• cmayfi: Ants measure distance by counting their steps. Scientists proved this by taking some ants out of a line and putting tiny stilts on them. Those ants then over shot the food source they were going too
• scary_warrior: Grizzly bears run as fast as the average horse

TIL Krakatoa’s eruption was estimated to be at 310 dB, the loudest sound ever. Well above the typical max sound limit of 194 dB (r/todayilearned)

• mryazzy: People forget decibels are logarithmic, not linear. This doesn’t mean twice the noise generated by a rock concert. It is many orders of magnitude louder.
• WontThinkStraight: How many decibels would the asteroid that killed the dinosaurs have been? Feels like that would have been louder.
• SpunNumeroUno: I wonder what it actually sounded like, just an explosion or something more complex… Hmm

Pope Leo called his bank’s customer service line. They hung up on him (r/nottheonion)

• Accurate_Koala_4698: “Yeah? And I’m the Queen of England”
• Totheendofsin: The poor teller waking up to find she’s part of an international news story because she hung up on what she assumed was a prank caller
• kahllerdady: My god would I love to be the call center supervisor on whatever shift THAT was!

What’s the best company to have on your resume as tech hiring is being reshaped? (Blind)

• apple145 (Meta): Role > Company especially after junior levels. If I’m a janitor at Anthropic, is that really impressive?
• jsueppoklk (Anduril): I think this is a stupid poll. Can that be an option?
• hd7Vat (DoubleVerify): I don’t think IBM was ever S tier since the ’80s.

Why does Leetcode still exist (Blind)

• takoyaki79 (Datadog): Leetcode was just a filter. Why do people not understand this. It sucked but actually straightforward to grind. You are going to miss it I promise. I honestly believe interviews will soon be build and deploy an entire product end to end in an hour. With a lot more room for interviewer bias. “Sorry your solution didnt have “taste””
• BeEvil_ (Google): Leetcode was always useless
• slackerswe (Microsoft): It’s a proxy to determine your ability to solve problems. It’s not perfect. Google was doing it before leetcode was a thing. It worked out for them, rest copied it.

How to deal with AI slop essay colleagues (Blind)

• EditConfig (Google): Paste their AI response to another AI and respond back with that response. Make sure to begin the prompt with “you’re a nitpicking, disagreeable, autist”.
• MomDonny (Disney Streaming Services): So you prefer “read the code”?
• funhero (Microsoft): At Microsoft there are a lot of Indian engineers and it is common for folks to use ai to help organize their thoughts. So they may also be using it in this way as a sort of “pseudo translator” to try to get their thoughts across better.

A Michigan farm town voted down plans for a giant OpenAI-Oracle data center. Weeks later, construction began (r/technology)

• rudebii: Im sure there are other means to make the data center go away, but the only ones I can think of will get me banned by Reddit’s AI moderation.
• Eskimomonk: Sounds to me like the people of that town deserve to own that data center and the profits of whatever it generates
• veracity8_: It’s crazy that data centers can get built overnight but when someone suggests legalizing duplexes in the Denver metro residents riot at city hall

xAI will be dissolved as a separate entity. (r/singularity)

• Fine-Drummer9812: This is what Elon wanted to do with OpenAI and Tesla
• AdAnnual5736: AKA jam all of the unprofitable companies into the profitable company that’s kept afloat by government contracts.
• MysteriousPepper8908: Seems like if you really believed in your AI efforts, you would want that as more than just a product of a completely unrelated enterprise.

TikTok’s algorithm favored Republican content in 2024 US elections, study finds (r/technology)

• temporarycreature: Figuratively speaking, my jaw has practically hit the floor, my eyes have rounded into perfect, incredulous circles of disbelief, and every fiber of my yellow fur is buzzing with the realization that the very results I expected to be found are actually found.
• adrr: Of course it did. China wants the GOP in power. They know they’ll run up the debt, not invest in infrastructure, not invest in cheaper electricity with solar and wind, cut spending on science, cut spending on education. GOP will just help makes the billionaires richer.
• Local_Fly_7359: China wants us weak with weak leadership.

I’m curious if “I’m curious” is the new em dash AI tell (r/webdev)

• Bodine12: Honest take? It’s 100% AI—and your instinct is right to call this out. Curious if any others here feel the same.
• remy_porter: I’d caution against looking for such simplistic tells. Like the em-dash, there’s a lot of chance for false positives. Ditto the “it’s not just x, it’s y.” I’d look for the broader feel of the text- to this day, LLM generated text just causes my eyes to slide right over it. It’s basically unreadable, not in the sense that it fails to look like text, but in the fact that it’s so devoid of information that there’s no reason to read it.
• bobtheorangutan: I’m curious — maybe I’m the AI

• Problem: Next Greater Element II
• Main tags: Array, Stack, Monotonic Stack

What the problem is really asking

The input is an integer array nums, but the array is circular. After the last index, the scan wraps back to index 0.

For each index i, the task is to find the first value that is strictly greater than nums[i] when walking forward through this circular array. If no greater value appears before returning to i, the answer for that index is -1.

Problem: Swap Adjacent in LR String

Problem gist

The string contains three characters: L, R, and X. Think of X as an empty space. The only allowed moves are:

1. XL -> LX, which moves an L one position to the left.
2. RX -> XR, which moves an R one position to the right.

Given start and end, the task is to decide whether start can become end after any number of those moves.

Why heat conduction matters

This article turns a materials-science result into a broader question about what physicists think the limits of matter are. Copper has long been the default metal for moving heat away from hot components. Its usefulness is not glamorous, but it is central to modern technology: electronics, power equipment, data centers and industrial systems all depend on getting heat out before performance drops or hardware fails.
