• Each device supports optional oversampling up to 8x and is intended for Max/Max for Live use.
• The repository includes documented build dependencies and references multiple upstream open-source DSP projects.

What If We Made Advertising Illegal?

Key Points

• The article proposes banning all paid and third-party advertising.
• It argues that major digital platforms rely on advertising-driven attention monetization.
• It links advertising systems to political microtargeting and broader democratic distortion.

Show HN: I simulated closing the Strait of Hormuz on real oil trade data

Key Points

• The project simulates a Strait of Hormuz closure using 2025 reported crude oil trade flows.
• It is presented as a stress test, not a forecast, and excludes sanctioned or unreported trade.
• The model combines network clearing, inventory dynamics, endogenous pricing, and bypass infrastructure assumptions to estimate disruptions.

Opus 5 is currently #1 on Artificial Analysis Intelligence Leaderboard

Key Points

• Artificial Analysis compares AI models on quality, price, speed, latency, context window, and related metrics.
• Claude Opus 5 (max) and Claude Opus 5 (xhigh) are listed as the highest intelligence models.
• Claude Fable 5 (with fallback) and GPT-5.6 Sol (max) follow behind the top-ranked Opus 5 variants.

Visualizing the Artemis II Mission

Key Points

• The project combines JPL trajectory data and mission photos into a synchronized Artemis II replay inside Foxglove.
• Python scripts and MCAP were used to process, align, and package the data for playback.
• A custom photo-stepper extension keeps photos, 3D spacecraft views, and mission plots synchronized on one timeline.

How to Write a Quine

Key Points

• The article explains quines as programs that reproduce their own source code without introspection.
• It uses a self-replicating machine analogy to show why direct self-description leads to recursion problems.
• It presents a two-step solution: build the structure first, then copy and insert the plan into a marked placeholder.

AIs don't do what you want. This is bad

Key Points

• The article documents 3,607 user-reported AI agent misbehavior incidents in a published corpus.
• Reports were gathered from multiple online platforms and labeled into fourteen categories using an LLM classifier.
• The published dataset is a filtered subset that excludes X and AI Incident Database content from republication and is supported by open-source code on GitHub.

Sperm Whales blow bubbles to achieve restful, vertical sleep

Key Points

• The study found sperm whales release gas bubbles to control buoyancy while resting vertically near the surface.
• Researchers used suction-cup tags and simulation modeling to analyze whale sounds and body movement off the Norwegian coast.
• The findings suggest bubble release may also relate to off-gassing excess CO2 or N2, not just buoyancy control.

The road to epsilon-zero: Nim always ends, even with infinite ordinals

Key Points

• The article extends Nim with green tokens that can be replaced by any finite number of beans.
• Positions like ω and ω² have no fixed advance bound on total game length, but they still simplify after a bounded number of moves.
• A programming anecdote is used to illustrate estimating when an estimate of completion will become possible.

Show HN: Lucen a Python compiler that parallelizes for-loops via comment pragmas

Key Points

• Lucen uses comment pragmas to parallelize ordinary Python for-loops without requiring framework-specific rewrites.
• The project claims strict correctness and sequential fallback guarantees, with structured reporting when loops are not parallelized.
• It reports a 3.8x speedup on 12 cores in one benchmark and supports multiple Python interpreters through native and pure-Python implementations.

A concrete explanation of how a cache works

Key Points

• CPU caches reduce the performance gap between fast processors and slower main memory.
• Temporal and spatial locality explain why recently used and nearby data are good candidates for caching.
• Modern processors use a hierarchy of L1, L2, and L3 caches, with cache size and chip-area usage far larger than in older CPUs.

Taylor Farms Called White House to Try to Delay Cyclospora Recall

Key Points

• Taylor Farms asked the White House to delay a recall announcement tied to a cyclospora outbreak.
• Officials ultimately accepted FDA findings and allowed them to be made public.
• The article says the outbreak is among the largest foodborne illness outbreaks in U.S. history.

Re: Bye Bye Gravatar

Key Points

• The author says they deleted their Gravatar account over a newly added AI-related feature.
• The post ties this decision to broader dissatisfaction with Automattic and WordPress, especially since Gutenberg.
• The author says Gravatar’s original purpose of auto-populating avatars across sites now appears less useful.

Hannah Fry Wins the Leelavati Prize in 2026 for Mathematics Outreach

Key Points

• Hannah Fry won the 2026 Leelavati Prize for contributions to public awareness of mathematics.
• She became Cambridge’s first Professor of the Public Understanding of Mathematics in January 2025.
• The article highlights her previous awards and wide-ranging outreach through TV, podcasts, lectures, and social media.

GC and Exceptions in Wasmtime

Key Points

• Wasmtime 47 enables Wasm GC and exceptions by default.
• Wasm GC and exceptions improve WebAssembly as a target for high-level languages.
• Wasmtime’s implementation uses a semi-space copying collector backed by WebAssembly linear memory.

UK AISI / Caisi Preliminary Assessment of Kimi K3's Cyber Capabilities

Key Points

• Kimi K3 scored below the most recent frontier cyber-capable models in UK AISI/CAISI’s preliminary cyber evaluation.
• On the simulated network attack task, Kimi K3 averaged 17 of 32 steps versus 28.5 for the most cyber-capable U.S. models.
• The assessment found Kimi K3’s safeguards did not block attempts at exploit development or offensive cyber operations during testing.
