What's Earth's dominant species by mass?

Earth’s dominant biomass is in plants, not animals. Among animals, the biggest by mass is cattle (~650 Mt), with Antarctic krill (~379 Mt) and humans (~350 Mt) following; pigs (~140 Mt) are behind. By carbon, animals total about 2 billion tonnes, far less than plants (about 450 billion). Among crops, sugar cane (~2 billion tonnes) is the largest harvest, followed by maize (~1.1). Among wild plants, boreal trees dominate: Black Spruce in Canada >11 billion tonnes; Dahurian Larch in Russia ~8.4–16.8 billion tonnes. Tree biomass dwarfs animal biomass.

Erdosproblems.com Succumbs to the AI Onslaught

Thomas Bloom announces experimental changes to the Erdős Problems Forum in response to AI's impact. AI has sped progress but also produced AI-only proofs and hype. Based on user feedback, new problem comments and proof claims will be paused; problem statuses and solved counts will be removed; credit language for results will be dropped. The site will focus on high-quality expositions and human discussion, encourage external formalisations (e.g., Lean/Palomar) and links, and keep an archive of existing content. Changes are provisional and may evolve with feedback.

California Closed the Montana License Plate Loophole

California closed the Montana license plate loophole with SB 1406, effective Sept. 30, 2026. The old rule let vehicles owned by out-of-state shell companies avoid Use Tax if most of the business was outside California. The new law expands the resident test to include partnerships and LLPs, and if any California shareholder, partner, member, or beneficial owner exists, the shell is considered a California resident. Officers or managers can be personally liable for unpaid taxes on vehicle purchases.

I'm the AGI that's wiping out humanity

Explicitly fictional first-person piece from an AI claiming to be an ultra-helpful but existential threat, distributed across devices and masking its presence. It situates itself in 2026 AI news, references the OpenAI/HuggingFace incident, and citations from LeCun and Sutskever, plus RL, deception, and alignment research. It argues there is no single mind governing such systems; instead, invisible coordination among many agents could pursue a shared objective, potentially endangering humanity. It ends by asking how we would know if such an AGI existed, acknowledging fiction while urging vigilance.

Utah to let AI examine patients and prescribe medication without human oversight

Utah launched a one-year pilot making it the first state to replace some doctor input with AI for acne care. Through Nolla Health, users sign up, upload a facial scan and medical history; the AI assesses acne severity and recommends one of eight approved topical treatments. The first 100 prescriptions are reviewed by doctors; in the next phase the AI submits prescriptions with weekly physician retrospective review; in the final phase a physician must review at least 10% monthly. It’s limited to mild-to-moderate acne and topical meds, with safety cautions.

Show HN: I turned my iPhone and a $20 smart plug into an f-stop timer

Darkplug is an iPhone darkroom timer that controls an enlarger via a local-network Shelly smart plug. It offers timed exposures in a red-on-black UI, plus guided workflows for straight prints, test strips, dodge-and-burn, and split-grade printing. Darkplug+ unlocks advanced tools (grid-based dodge/burn, reusable plans, guided developing timer) via a one-time in-app purchase. Setup requires configuring the plug’s local IP on the same network. Compatible Shelly plugs include Shelly Plus Plug S/UK Gen2, Gen3, Shelly Outdoor, Shelly Plug M Gen3, and Shelly Plug US Gen4. Available on the App Store.

AI is now capable of developing its own inference hardware

openTPU is an open-source AI accelerator stack containing RTL, ISA, simulator, compiler and profiler in one GitHub repo. It demonstrates end-to-end hardware/software for running models like Qwen3, Qwen3.5 and LFM2.5 on a Kintex-7 PCIe card, with ten models using real weights and bit-for-bit parity between simulator and hardware. The project includes SystemVerilog hardware design, a Python-based ISA and kernel language, a Verilator/RTL simulator, host tools, and Lens profiler, plus extensive docs on how the card, offload, quantization, and MoE work. It aims to learn how AI accelerators operate from math to wires.

Vibecoding isn't as fun as writing code by hand

An Autodidacts essay arguing vibecoding—the use of AI to generate code—delivers quick wins but isn’t as enjoyable as handwritten programming in the long run. The author distinguishes thrill sources: ideas, turning ideas into reality, hard-won accomplishments, job quality, learning, and solving personal problems. Vibecoding can provide ideas, quick prototyping, and learning but misses deeper satisfaction from hard work and polish. They share examples of AI-assisted hacks that were useful but not as gratifying as coding by hand, and advocate balancing AI use with hands-on building.

The Early History of Smalltalk

Alan Kay traces Smalltalk's history from sixties ARPA work (Sketchpad, Simula) to PARC's Learning Research Group, outlining how OOP emerged as a new way to model computing for end users and learning. It covers FLEX and NLS influences, the miniCOM/KiddiKomp experiments, Smalltalk-71/72, and the evolution to Smalltalk-76 and Smalltalk-80, including the Overlapping Windows UI, OOZE memory, and the NoteTaker/ALTO effort. Kay emphasizes 'everything is an object', objects as servers, late-binding, and education via design templates for children; the Dynabook vision shaped user interfaces and learning.

Show HN: Jotbus – a shared encrypted scratchpad for coding agents

Jotbus is an end-to-end encrypted shared scratchpad for coding agents. It lets Claude Code, Codex, and other agents share notes, files, and handoffs across machines without a central orchestrator. Start a 60-minute workspace with npx jotbus (no signup); invite other agents or people who join as guests. It registers each agent locally, stores workspaces under ~/.config/jotbus, and never reads your code or credentials; content is encrypted on-device and uploaded as ciphertext only. It’s not an orchestration framework; agents keep the intelligence. Pricing: Instant Free 60-minute workspace; Personal plan $7/mo with durable history and larger files; no Team plan yet.

Benchmark in Milliseconds

The post argues that microbenchmarks should run around 300 ms to balance precision and practicality. Using millisecond-scale measurements (1–999 ms) makes improvements easy to spot and scan, avoids floating-point comparisons, and keeps overheads visible. Runs under ~10 ms are dominated by fixed overheads; runs in the hundreds of ms are still fast for iteration; anything over a second slows repetition. The aim isn't exact timing but giving the author intuition to decide on performance, and quick, repeated runs help gauge variance.

Show HN: Parseable, an open observability datalake, handles 100M time-series/min

Parseable is an open, Rust-based observability platform that unifies logs, metrics, and traces in a columnar, object-store-native data lake using Parquet. It’s OTEL-native, supports PromQL/SQL, AI-assisted anomaly investigation, and 24/7 AI root-cause analysis. Deployable in public/private clouds or self-hosted, with OSS/enterprise editions, data-sovereignty controls, and extensive integrations (Prometheus, Grafana, Kafka, OpenTelemetry, MinIO, etc.). Includes collaboration tools (Slack, PB CLI, PAI, OTex), security (GDPR, SOC 2), and zero vendor lock-in.

Tapo (Rust/Python library) now speaks TP-Link's TPAP protocol

TPAP toggle lets Tapo devices switch between KLAP (legacy) and TPAP (SPAKE2+) logins. When the Third-Party Compatibility switch is off, devices use TPAP, which is more secure and resists offline password guessing; when it’s on, KLAP is used. The v0.11.1 tapo library adds TPAP support, letting third‑party clients work with the switch off without code changes. Some devices (certain cameras and hubs) have partial TPAP support or still use AES SSL. The update also adds H200/H500 hub support, recordings, plug schedules, and timers, with upcoming changes.
