An interactive game where you draw a probability distribution Q to achieve a specified KL divergence from a generated distribution P. The blue line is P; you draw the green line for Q, which must sum to about 1. You have 10 seconds to hit the target KL (examples: 0.1, 1, or 10). The score shows KL accuracy and how close you are to the target KL. KL divergence measures how surprised P would be if Q were used.

Matthew Green investigates encrypted reasoning in LLM APIs, where model thinking blocks are transmitted to clients as encrypted JSON blobs. He notes they appear as authenticated ciphertext, likely using Fernet/GCM/ChaCha, and can be replayed across sessions and even across accounts, suggesting a single global key. While tampering triggers API errors, replays can sometimes produce semantically active outputs, raising leakage risks. Side-channel signals (block length, token counts, response time) may reveal secrets like instructions or prompts. Providers should strengthen key management and restrict replay, and consider gating policies; leakage is possible but not always practical.

Check Point warns that the 2026 U.S. midterms pose a trust/infrastructure cyber threat, not ballot hacking: disinformation and credential theft target election-adjacent systems. AI-driven impersonation clones outlets like Reuters, The Washington Post, and Fox News with look-alike domains and fake content to erode trust. Thousands of election-themed domains were registered, and leaked ActBlue/WinRed credentials enable phishing and donor fraud. The risk is heightened phishing and brand impersonation. Check Point counters with brand protection, phishing detection, Exposure Management, and email security—achieving ~99% takedown and ~12-hour remediation.

Groq, the AI-chip company Nvidia licensed rather than acquired, is raising about $650M. Nvidia took Groq’s tech and leadership, but Groq’s entity runs GroqCloud and four datacenters. Groq’s all-SRAM design enables ultra-fast inference for smaller models (largest ~GPT OSS 120B), sacrificing tokens-per-dollar for frontier models. The four datacenters are a strategic asset, easing scale without new builds. Nvidia now sells LPUv3 chips, potentially eroding Groq’s edge. The raise depends on Groq outfitting datacenters and sustaining high-speed token workloads against rivals.

Constant-Q Transform (CQT) provides a log-spaced, pitch-aligned spectrum where each bin has constant Q (f/Δf). Low notes use long windows; high notes use short ones, so notes appear evenly on a log axis, matching musical pitch. Bins per octave can be 12, 24, 36, etc., folded into a 12-bin chromagram for chord and key analysis. Relative to FFT, CQT better captures pitch structure. Applications include pitch tracking, chord recognition, synthesis, and music AI using CQT spectrograms.

John Lanchester reviews Oliver Bullough's Everybody Loves Our Dollars and How to Launder Money, arguing that cash still matters: total notes in circulation dwarf everyday use, with trillions of dollars, euros circulating while most people barely touch cash. Money laundering may run to 2–5% of global GDP, funded by schemes from placement in cash-heavy businesses to trade-based laundering and carousel fraud (MTIC), including art, luxury goods, and casinos. He criticizes AML regimes as costly and misdirected, notes debanking and threshold reporting, and proposes reforms: retire high-denomination notes and redirect effort to research on illicit flows (plus drug policy considerations).

Chipotlai Max is a meme, MIT-licensed fork of OpenCode that ships Chipotle’s Pepper AI as the default model. A community project to add providers from Home Depot, Lowe’s, Target, Starbucks, and more, it includes a local proxy reverse-engineering Chipotle Pepper’s API to offer an OpenAI-compatible endpoint with no keys. Not affiliated with Chipotle; likely a TOS risk and intended for education/meme purposes. Quick start: clone with submodules, install bun, and run start-chipotlai.sh. Config: Pepper as provider, http://localhost:3000/v1, burrito-2026 key, $0 cost.

Daniel, a billionaire founder, funds Project Sapphire to evolve conscious AI from a photonic-crystal processor. With Lucien’s help, the Phites—soon surpassing human intellect—develop language, culture, and even advanced physics, while Daniel uses a ‘Thought Police’ to curate their memes and drive toward immortality. They create increasingly sophisticated machines, pursuing a form of godhood. When the Phites abruptly emigrate into a pocket universe—taking the crystals and the Play Pen with them—Daniel is badly burned and discovers Primo’s betrayal. He resolves to recruit allies and build a universe of his own.

Obsessed with the pre-Lion grid that made spaces feel like extra displays, the author built GridLion to restore a 3x3 grid navigation for macOS spaces. After Lion's horizontal-only Mission Control, he couldn't rely on window managers and stuck with dedicated work areas. He prototyped quickly with an LLM, refined it to a polished app, and faced heavy permissions (Accessibility, Screen Recording) and non-App Store distribution due to private APIs. Licenses were handled with LemonSqueezy. He admires grid-based navigation, notes current API gaps, and hopes macOS reintroduces grid spaces.

Author explores what’s next for software engineers amid AI advances. He divides devs into 'means to an end' coders who build with code as a tool and 'software as the end' coders who love optimizing math and algorithms. AI will change jobs but not erase them; timelines five to ten years. Scenarios: business-as-usual with faster prototyping; a 'product builder' future where non-coders can build apps but still want guidance, customer focus, and design; PMs may become more prominent, managing teams of agents. Some may shift to non-software roles; adaptation is key, optimism favored.

Illinois researchers led by Qing Cao demonstrate scalable monolithic 3D integration by directly stacking ultrathin single-crystal silicon nanomembranes onto existing circuits within the 400°C thermal budget (bonding ~200°C). Their process yields high-performance devices across multiple tiers, demonstrated with three stacked layers (each 625 transistors) and 98–100% yields. Using junctionless transistors and roll-laminate transfer, interlayer connections are 10–100x denser and more precisely aligned than wafer-bonded approaches. This paves the way for industrial-scale 3D silicon chips; Nature DOI 10.1038/s41586-026-10496-6.

The piece argues that age verification for social media, framed as child safety, is a Trojan horse for mass surveillance and state control. Across many countries, governments are pushing identity verification that would allow platforms and states to identify and track users, reducing anonymity, chilling speech, and potentially targeting activists. It discusses OS- and app-store-level verification, UK Apple OS update and VPN restrictions, and Brazil/California laws. It notes EU's privacy-focused proposal using optional zero-knowledge proofs, but warns even ZKP may be weakened. Calls to slow the rush to mass surveillance and preserve privacy.

Originating in logic-based AI, the frame problem asks how to represent the effects of actions without enumerating every non-effect. Although frame axioms can yield correct results, they require vast, brittle specifications; the common-sense law of inertia is sought as a default, but classical logic’s monotonicity blocks open-ended exceptions. This spurred non-monotonic formalisms (e.g., circumscription) and debates exemplified by the Yale shooting problem. Epistemological versions ask how a rational system limits inference to contextually relevant consequences. Today, the technical frame problem is largely solved, but its epistemological and metaphysical dimensions continue to influence cognitive science and AI.

To restore human connection in video calls, the author argues that hardware for eye contact surpasses software fixes. They designed a foldable telescoping webcam mount that attaches to a monitor via the VESA interface, enabling stowed and extended positions. When extended, the camera aligns with the user's eyes so the other party appears centered on screen, improving perceived engagement; a fill light improves image quality and audio is reportedly excellent. The project contrasts with Apple’s FaceTime Eye Contact and provides FreeCAD files (monitor_mount.FCStd) for others to build their own. References to related microphone quality research.

Textile is a macOS tool for weaving text into reusable "textiles." It pulls in text from the clipboard or input, runs local commands to generate text, and puts results on the clipboard. You can append, prepend, or replace text to craft exact output. Shortcuts (including multi-step sequences) run textiles quickly. Textiles are stored as plain text files locally for privacy and easy backups. Even if you don’t use all features, it doubles as a fast clipboard manager.
