A Delaware jury found Arm breached Qualcomm's Architecture License Agreement by withholding patches and verification tools for Qualcomm's Oryon cores and by interfering with Qualcomm's Meta business, but awarded only nominal damages of $2 ($1 per claim). Arm won most other claims under a separate Technology License Agreement. The major unresolved issue is whether the breach lets Qualcomm suspend five years of ALA royalties (potentially billions); Arm calls the penalty unenforceable. An appeal is likely; this follows a prior Nuvia-related ruling.

Konnect is a native KiCAD 10 plugin (Rust binary) that enables AI-assisted PCB design via the MCP protocol, exposing ~217–228 schematic, layout, routing, design-review, and manufacturing tools to Claude or any LLM. It runs as a single static binary (20–25 MB) with no extra dependencies, communicates with KiCAD's IPC API for real-time edits with undo/redo, and supports schematic capture, PCB layout, ERC/DRC, design checks, and production exports (Gerbers, BOM, pick-and-place). It bundles KiCAD skills for Claude/Codex and includes Nimrod, a web-research MCP server for live part data. Beta release; AGPL-3.0 (commercial licenses available).

Hebrew University researchers created BioPykrete, a bio‑inspired ice composite that’s about 10 times stronger than ordinary ice and can absorb around 70 times more energy before breaking. By embedding cellulose nanocrystals and a bespoke protein (CBM3a‑AFPIII) that glues the crystals to ice, they achieve controlled molecular bonding rather than simple fiber mixing. It’s aimed at construction in remote, cold regions where traditional methods struggle, with no concrete or steel needed and a lower carbon footprint. It’s still a small-scale proof of concept; durability, crack propagation, and optimization remain to be studied.

BBC Science Focus reports a review of 38 Japanese surveys (1974–2024) showing rising sexual inactivity: about half of people in their 20s have no sexual experience; around 10% reach their 30s without sex. In the 20–49 group, roughly 50% haven’t had sex in the past year, with about 60% of men and 51% of women aged 20–24 sexually inexperienced by the 2020s. Proposed causes include long work hours, dating costs, marriage pressures, heteronormativity, and limited sex education; results vary across surveys.

Author describes a JavaScript exploit to invoke arbitrary functions without parentheses by abusing error stack handling. By overwriting Error.prepareStackTrace and manipulating Array.prototype.toString and Object.prototype.message through prototype pollution, the stack array is coerced into a payload. Then a function is created via the Function constructor, and the payload is invoked using valueOf or toString tricks. The post includes a concrete example payload and suggests trying it in the browser console.

Coscia and colleagues estimate the Economic Complexity Index (ECI) for the Western Roman Empire using LIST, a Latin inscriptions dataset with precise locations. They correct for biases: status bias in funerary/honorific inscriptions, gender imbalance, farmer underreporting, and historiography bias, to infer occupation counts by province. Latium has the highest ECI, and the data show a nested, complex pattern. They further compute ECI using modern political borders and find a significant Spearman correlation with contemporary ECI across about 23 countries, suggesting persistence of economic complexity. Future work includes improving bias corrections and integrating Greek inscriptions (GIST) with Latin data.

The post presents an O(1) amortized two-stack sliding-window aggregation for arbitrary associative operations, solving non-invertible cases (min, quantiles, HyperLogLog, etc.) where simple sums fail. It generalizes the two-stack queue using empty, unit, combine, finalize to describe any aggregate. The algorithm maintains two stacks (values and cum_aggs) and a running values_agg; push updates values_agg, pop drains values into cum_aggs, and eval combines the last cum_agg with values_agg to produce the window result. It uses O(w) memory and O(1) amortized per operation, preserves order, and handles NaNs/outliers; notes floating-point non-associativity but remains practical with compensated summation.

An essay reframes insider information as a legal, career edge. Using Nokia in 2007, workers with inside knowledge traded their careers by moving to Apple/Google rather than money. Most do nothing, waiting for numbers or official confirmation. The read is fuzzy if you can’t assess customer energy, pivot speed, or AI impact on your role. An AI Impact Map shows where AI lands in your job (free for now). Career trades are usually small: move toward growing initiatives or deepen ties to successful teams; sometimes the edge is recognizing you’re already in a good spot.

Folders is an esolang by Daniel Temkin where programs are pure nested folders; names are ignored, and code is encoded by the count and order of subfolders. It offers dematerialized code with potentially infinite storage, since data is encoded in folder names. It began as a Windows language; git ignores empty folders. Folders FS stores data; an emulator and a GitHub implementation exist. Commands and expressions are determined by the number of folders in the first child, with types like float, string, and char. Visualizations include Truth Machine and Fibonacci examples; it is one of Forty-Four Esolangs.

New York City's Central Park horse-drawn carriages are set to end after a deal between Mayor Zohran Mamdani and City Council Speaker Julie Menin. The phased ban takes effect June 1, 2028, aided by Romanch Mahajan’s death from a runaway carriage. The bill, dubbed Romanch’s Law, includes a worker-transition framework, prohibits selling horses for slaughter, and designates a city agency to manage retraining across agencies; TWU Local 100 criticized the plan as lacking economic relief for workers.

Gentoo's Chromium package maintainer declared last rites on Sept. 24, masking the ebuild and ending official maintenance. The decision cited the upstream's massive, rapidly updated codebase, a complex build with bundled toolchains, Go and Rust dependencies, long compile times, and frequent architecture limitations; upstream CI unreliability and volunteer burnout. Other distros face similar issues, but Gentoo concluded sustainable maintenance isn't viable here. Alternatives include Bentoo/overlays, Flatpak, or switching distros; restoring would require a dedicated multi-person team and significant effort.

On Ludicon's four-year anniversary, Ignacio Castaño reflects on starting Ludicon to work independently, speed, risk-taking, and deep focus, despite limited commercial success. He discusses a tough 2022 for game middleware amid industry layoffs and engine consolidation (Unity/Unreal, Epic's RAD buy). He pivoted to Spark and real-time texture compression to handle runtime content and storage constraints amid AI-driven content growth and memory shortages. While AI hasn't replaced codecs, it enhances coding and tooling. He believes real-time compression offers a better future than traditional RDO encoders, and is cautiously optimistic.

Order of the Sinking Star, Thekla’s sprawling puzzle, reworks four indie Sokoban‑style titles into a vast, interlocking map. Puzzles start simple—Mirror Isles, Promesst, Heroes of Sokoban, Skipping Stones to Lonely Homes—and gradually fuse their mechanics across the overworld, delivering clever, sometimes revelatory design rivaling Super Mario Maker moments. But its scale breeds fatigue. it’s an expert, relentlessly escalating experience with few resets or satisfying payoffs. Trust falters beyond the screen amid controversy around Jonathan Blow’s politics, complicating reception. If the 500‑hour claim is real, it’s a marathon for puzzle fans, releasing Oct 8 on Switch 2, PS5, and PC.

Deno’s team is joining Cloudflare, winding down the runtime over the next year, with celld folded into workerd; JSR will continue on Cloudflare infrastructure. Bun recently joined Anthropic. While Deno never gained production-scale dominance, its competition spurred a healthier ecosystem: Node remains dominant in 2026, yet features like permission-based security, TypeScript-first input, ES modules, and web APIs migrated into the broader ecosystem. Deno later embraced npm compatibility, and the npm/Node ecosystem parity accelerated via Bun and Cloudflare’s efforts. The shift shows independent runtimes being absorbed into company-backed layers, with JSR and registries evolving. Thanks to Deno’s team.

Chromium developer Sharon Yang compared Google and Igalia at FOSSY 2026, highlighting different operating models. Google, a huge, investor-owned company with layered hierarchy, offers advanced internal tools and a mix of client-driven feature work; Igalia is a 180-person employee-owned cooperative with a flat structure, shared pay, and decision-making via assembly. Both work on Chromium but differ in project selection, access to proprietary code, bug-tracking visibility, and focus—Google emphasizes features and promotions; Igalia emphasizes code health and interoperability. The talk discussed hiring, governance, promotions, and challenges of scaling a flat coop, and open questions about future tooling sharing.

Non-determinism in LLMs isn’t a bug but a new paradigm. There are multiple paths to the same result, so software can be built as probabilistic actors guided by deterministic tools. By using context engineering, MCP, skills, harnesses, graphs, and memories to reduce output randomness, engineers create agent-like abstractions that perform precise, tested operations. These tools yield the same correct outcome on every run with fewer tokens. The pattern—AI-built abstractions and agentic automation—reshapes modern software and DevOps, even for mission-critical systems.

Carolyn Marvin, a Center City Philadelphia woman, was arrested for blocking an Uber delivery robot near Reading Terminal Market on Filbert Street. Police say she repeatedly blocked the robot and ignored officers’ commands to move, and she was charged with disorderly conduct. Marvin says she’s protesting delivery robots because they replace human workers and claims the action was protected speech. She has confronted robots before and plans to continue protesting, with witnesses noting the incident went viral online.
