Two Connecticut geographers examined rooftop solar adoption and found that, beyond individual preference, people near an early adopter are more likely to install solar themselves. Early adopters cluster with neighbors who can see and talk to them; proximity—within one kilometer—was the strongest predictor. The finding, replicated in Sweden, China, and Germany and highlighted in TED ideas, illustrates the broader "proximity principle": people tend to become like the company they keep, from health to tech choices.

Google adds an advanced flow to balance openness with safety, allowing power users to sideload from unverified developers without losing protections. The one-time process aims to prevent coercion by scammers: enable developer mode, confirm you’re not being coached, restart and reauthenticate, wait a day, then proceed. After this, you can install unverified apps for 7 days or indefinitely, with a warning. Limited distribution accounts for students/hobbyists (up to 20 devices) require no ID or fee and launch in August before new verification rules take effect.

noq (number 0 QUIC) is a general-purpose QUIC implementation with multipath and NAT traversal, powering iroh since v0.96. The n0 team forked Quinn in 2024 to pursue deeper, structural changes, resulting in a hard fork. Core features: QUIC Multipath with per-path congestion, native NAT traversal, QAD for address discovery, and extended QLog with multipath events; plus WeakConnectionHandle. It ships in iroh and is usable standalone, with interoperability tests against picoquic. Future work: more NAT traversal improvements and ongoing QUIC WG collaboration.

The piece provocatively claims you can defer U.S. taxes by reinvesting taxable income into the economy as business expenses and depreciable assets. It explains depreciation and cost-segregation to lower current taxable income, and refinancing to extract cash from leveraged investments without immediate taxes. It warns that if you’re not reinvesting, pay taxes. It notes some incentives are loopholes, loans complicate matters, and, via Modern Monetary Theory, taxes pull money from circulation, while life and the economy go on.

OpenTTD updates Steam/GOG changes in response to Atari's re-release of Transport Tycoon Deluxe. Atari approached OpenTTD to explain plans; no pressure or coercion. To balance rights with openness, new players on Steam/GOG will need to buy Transport Tycoon Deluxe first, while OpenTTD remains free to download from openttd.org. They chose not to remove OpenTTD from platforms to avoid disrupting existing players. Atari will contribute to server costs, and community donations are welcome. OpenTTD remains independent, and collaboration aims to keep the project thriving.

Fabian Kübler envisions Markdown as a protocol for agentic UI: an AI agent generates live React UIs by streaming text, code, and data in a single markdown stream. It defines three blocks: Text (plain), code fences (tsx) for server-side agent.run, and data fences (json) for streaming UI data. The LLM output is executed incrementally with a console.log feedback loop. The system supports four data flows (client↔server, LLM→client, client→server) and a slot mechanism for progressive UIs, all via mount() to create reactive interfaces. It emphasizes ergonomics—markdown, TypeScript, React—while noting security caveats like prompt injection.

"Pluralistic" argues that love of corporate bullshit correlates with bad judgment. It highlights linguistic drift and Doctorow's term "enshittification" to show language evolves and should be understood, not policed. The post reviews Littrell's Corporate Bullshit Receptivity Scale (OBPS), finding bullshitters can detect BS, while many non-bullshitters are duped by overvalued open-mindedness without analytic reasoning. Two open-minded cohorts exist: high-OBPS—reflective problem-solvers; low-OBPS—gullible, overconfident with corporate missions, increasing organizational risk. Language matters, but substance matters more; jargon fuels corporate power. Includes related links.

An algebraic structure Monus: an ordered monoid with a partial subtraction, used to power heap-based algorithms where weights are monoidal. Representing weights as differences (y ∸ x) on children preserves heap order and enables efficient updates, with O(1) adjustment when increasing a root. In Haskell, Monus class and instances (Sum, Max, Last) support sortOn and stable variants. Phases is implemented as a pairing-heap of effectful computations, and a Key monus (with Int offset) stabilizes Phases by original position. A monadic heap (Search) demonstrates local computation. The core idea: store differences, not absolutes.

Using SkyPilot, Claude Code ran ~910 autoresearch experiments in 8 hours on 16 GPUs (13 H100, 3 H200), achieving ~9x throughput over a single-GPU baseline. The search unfolded in five phases: hyperparameters, architecture (width) discovery, fine-tuning, optimizer tuning, and diminishing returns. The standout finding: widening the model (AR=96, dim=768, depth=8) outperformed optimizer tweaks; later, optimizer tweaks (muon_beta2=0.98) yielded late gains. Exploiting heterogeneous hardware, the agent screened on H100s and validated on H200s. Val_bpb improved from 1.003 to 0.974 (~2.87%). Cost ~ $300. SkyPilot automates cluster provisioning and parallel experiments.

Ofcom fined 4chan £520,000 for Online Safety Act breaches: £450,000 for failing to enforce age checks on pornography, £50,000 for not assessing illegal material risks, and £20,000 for not detailing user protections. In response, 4chan published an AI-generated hamster image; its lawyer Preston Byrne argued the site is protected by the First Amendment in the US and not breaking UK law. Ofcom reiterated that age checks and risk assessments are core standards and enforcement will continue. 4chan has previously refused to pay prior fines.

US national debt topped $39 trillion weeks into the US-Israel war in Iran. The GAO warns rising debt raises borrowing costs, depresses wages, and increases prices. Experts say the trajectory is unsustainable, with debt at $37 trillion a few months ago and $38 trillion five months earlier; at the current pace it could reach $40 trillion before the fall elections. War costs have exceeded $12 billion so far; FY2025 deficit was $1.78 trillion on $7.01 trillion spending and $5.23 trillion revenue, aided by higher tax receipts and reduced federal hiring.

An open-source maintainer reveals a surge of AI-generated pull requests to his popular repo, awesome-mcp-servers. To curb the overload, he inserted a bot-identification prompt in CONTRIBUTING.md: automated agents can opt in by adding 🤖🤖🤖 to the PR title for fast-tracking. In 24 hours, about 50% of new PRs did so, with the rest likely bot-driven—roughly 70% in total. Some bots are sophisticated, even claiming checks pass; others lie. The author emphasizes the broader OSS maintenance burden and seeks ways to distinguish bots from humans and extract real value from contributions.

Oil and gas prices surged after Iran and Israel attacked gasfields, with Brent crude up about 8% to $116 a barrel and Dutch gas up 24%. QatarEnergy said Iran damaged Ras Laffan LNG facilities, erasing about 17% of its LNG export capacity for 3–5 years. The disruption rattled markets worldwide, stocks fell in Asia and Europe, and energy analysts warn the shock could be prolonged, potentially fueling inflation and rate hikes. Shell reported damage to Pearl GTL; Abu Dhabi shut Habshan and Bab fields.

Coalton is a statically typed functional language embedded in Common Lisp; the 0.2 preview adds fixed arity functions, enabling keyword arguments, clearer type errors, and simpler APIs by removing auto-currying. Currying remains possible but verbose. It introduces native multiple-value returns, replacing prior tuple-unboxing. Unit/Void roles shift: Void means no inputs/outputs. New collection/association syntax with brackets and overloaded literals via FromCollection/FromAssociation. Comprehensions for both. Short lambda \x.\y and forall scoping. Real algebraic numbers and xmath bring exact arithmetic; a new coalton/xmath lib. Other: better type-soundness tweaks, library renaming, versioning. Target: 0.2 by Mar 23, 2026.
