Knitting looks humble because its basic unit is so familiar: a loop of yarn pulled through another loop. The Scientific American Advances article “Knit Picking” shows why that simplicity is deceptive. A knitted sheet is not just a soft grid. Each stitch can bias the fabric to bend, twist or curl, and those local tendencies can combine into large, complicated three-dimensional forms. That is why a T-shirt hem can roll when cut, why patterned knitting can produce ridges and folds, and why predicting a finished textile from its stitch chart is still hard.

This summary covers The Economist’s May 31st, 2026 Essay article listed in the contents as Modern war and published under the headline The crucible of transparency.

War in the age of exposure

The article argues that modern war is being reshaped by a new, incomplete but powerful form of battlefield visibility. Soldiers, vehicles, aircraft, missile launchers and command posts are harder to hide than before because cheap sensors, satellites, drones, software networks and precision weapons are knitting the battlefield together. The result is not omniscience. Fog, deception, jamming and geography still matter. But armies now fight under more eyes, and those eyes can often be connected quickly to weapons.

ICE detainees are dying by suicide at an ‘alarming’ rate, an AP investigation finds (r/news)

• EldenLordGodfrey: Every suicide is a murder by ICE
• blckout_junkie: This is a feature for them, not a bug. I have given up hope for the future at this point.

Iran’s president offers resignation, citing total takeover by IRGC commanders (r/worldnews)

• Jonathan13211: Aren’t the IRGC even more hardline anti peace?

• Panzerkatzen: The IRGC are downright fanatical.

In Germany, deliberately engaging in catch and release only fishing is illegal and considered cruelty to animals (fishing for food is fine). How do you feel about that? (r/AskReddit)

• BunnyCheeky: You caught it in its natural habitat without planning to make it your family’sdinner. Giving it existential crisis by lifting it out of H2O then releasing back to the water with ptsd. Give the fish a lawyer and it will immediately sue you.
• Friendly_Excuse1432: This is why proper catch and release matters so much. A fish can survive being caught, but rough handling, fingers in the gills, excessive squeezing, and stripping off its slime coat can seriously reduce its chances. If you’re going to release it, at least give it a fair shot. Otherwise, keeping it is arguably more humane than pretending it’s fine after being manhandled for a photo.
• DadsAfroButter: Give the fish a lawyer, it will sue you for a day. Give the fish a legal team, and he’ll lobby to remove contaminants from the waterways for life.

What feels legal but is actually illegal and will possibly get you arrested? (r/AskReddit)

• ToomintheEllimist: Huh. Today I learned. I used to do that all the time back when I always had tons of coins on my person (from tips) and lived in an area where lots of foreign tourists had trouble understanding the meters.
• willstr1: IIRC the theory behind this (or at least what the law makers claim as the theory behind this) is that parking meters aren’t just about revenue but about discouraging people from staying parked in one spot for so long, so it’s literally designed to be inconvenient, good Samaritans putting coins in the meter reduces that intentional inconvenience.
• righteouspower: Trying to get your consigned Legos back from Bricks and Minifigs, apparently.

Biggest mistake of my life: leaving Google (Blind)

• ablox (Roblox): Yeah for all those who think like that, pleeeeaaaase stay at Google. Don’t come over here, we already have enough of your kind here, ruining the place.
• JYSj74 (Datadog): Xooglers finding out people work harder in other companies is always hilarious.
• bbbgo (Google): Companies are not static. Google you left probably doesn’t exist anymore.

RIP Design and customer support – the first victims from AI replacement (Blind)

• yaldaboink (Lucid Motors): Companies that outsource customer support to chatbots are satanic
• Lvru34 (Microsoft): I will like human customer support. I hate these robots response
• lambdaops (Amazon): AI does shit in design. It’s useful to create a pamphlet , but nothing more if you are looking for serious work. At best it can help designers automate boring work or try out some new inspirations.

Huawei chairman thanks the US for export restrictions on chips, says it supercharged China’s semiconductor industry — Washington’s export controls encouraged Chinese firms to invest in R&D and build their own tech stack competing with American tech (r/technology)

• zleuth: … As we all knew it would.
• Nail_clippings_Pete: At their work rate the espionage will reverse.
• Legote: Supercharge or not, they were going to do it anyways as they did with almost every industry the US “had” and advantage in.

Microsoft is threatening legal action for disclosing exploits / The company is feuding with a security researcher publicly posting vulnerabilities. (r/technology)

• TheFoxsWeddingTarot: Highlighting the importance of ethical hackers to our safety.
• Red_Eye_Insomniac: So they want to ensure that discussions about windows exploits only happen in criminal hacker groups and dark web forums rather than out in the open? Oh yeah that makes so much sense.

Mystery company accidentally blew $500 million on Claude AI in a single month — failed to put usage limit on licenses for employees (r/technology)

• Fateor42: Would be funny if they can’t pay and just declare bankruptcy leaving Claude holding the bag.
• film_composer: That’s an interesting thought… If a company goes bankrupt because they blew through all of their money on an AI-generated product, is there any legal protection against the company’s owner just keeping what was generated and taking it to a new company? In ordinary circumstances, assets can be repossessed, but what happens when the asset is more abstract? There’s probably an obvious answer, but this is out of my wheelhouse.
• Nobody_Important: AI companies suddenly caring about ip laws would be both hilarious and very on brand for 2026.

Quick facts

• Difficulty: MEDIUM
• Problem: Validate Binary Search Tree
• Topics: Tree, Depth-First Search, Binary Search Tree, Binary Tree

Problem gist

Given the root of a binary tree, decide whether the tree is a valid binary search tree.

The important detail is that the BST rule is global, not just local. A node in the left subtree must be smaller than the root, not merely smaller than its parent. A node in the right subtree must be larger than the root, not merely larger than its parent. The same rule repeats at every node.

What happened

Microsoft Research’s official research blog published Ire identifies another LOTUSLITE specimen, a June 12, 2026 post about using Project Ire, Microsoft’s autonomous malware-classification agent, to reverse-engineer a LOTUSLITE variant that largely evaded normal indicator-based detection.

The important detail is not just that an AI system labeled a binary as malicious. Microsoft ran Ire on a Windows DLL sample without giving it origin metadata, telemetry, a threat-intelligence prompt, or a family name. The agent used decompiler-based tooling and produced a function-by-function behavioral report covering installation, command-and-control packet structure, command IDs, persistence, obfuscation, and decoy behavior. Microsoft then compared that report against Acronis’s public LOTUSLITE write-up and found the same underlying malware family shape, even though the sample’s hash was not in the published indicator list.

From a Walk to a Theory

Jack Murtagh’s article begins with a puzzle that looks like a civic pastime, not the seed of a new field. In 18th-century Konigsberg, residents wondered whether someone could walk through the city and cross each of its seven bridges exactly once. The bridges connected two islands and two riverbanks, and every attempted route seemed to force a repeated crossing. The question was simple enough for nonmathematicians to ask, but it resisted the mathematical tools available at the time.

This summary covers The Economist’s May 31st, 2026 Finance & economics Buttonwood column listed in the contents as Giga-IPOs and published under the headline The incredible shrinking stockmarket.

A strong market with fewer public companies

The article argues that America’s stockmarket can look triumphant and diminished at the same time. Major indices are at record highs, but the public market itself is thinner than it used to be. The number of initial public offerings has fallen sharply from the pace of the 1990s, and the count of listed American companies has dropped from about 8,000 in 1996 to roughly 3,900 last year.
