IR imaging cannot resolve individual SRAM cells at 22 nm, but can bound total RAM by counting macros and data-path widths. This lets users verify RAM claims against fabrication and constrain hidden memory, reducing attack surfaces. While a few extra bytes could theoretically be hidden, overhead, architectural constraints, and IR/laser/interferometry measurements make such additions expensive and detectable; destructive SEM can confirm. The post dives into SRAM macro structures and alignment, and encourages readers to explore silicon with IR techniques.

Michael Burry questioned SpaceX and Anthropic valuations, saying neither is worth $1 trillion. In Substack chats, he argued SpaceX's S-1 shows no basis for a $1–2 trillion valuation despite rumors of a $2T target, noting $18.7B revenue and a $4.9B net loss. He also questioned Anthropic's $965B valuation, warning AI-model costs are expensive and computing power will be commoditized, making current demand signals unsustainable. He joked he would need to count to 1 trillion before paying that price.

Adafruit reports receiving a May 22, 2026 demand letter from Fenwick & West on behalf of Flux.AI/Defy Gravity, demanding it stop publishing an article alleging false and potentially defamatory claims about Flux, including IP, traction, and user base, and citing the Computer Fraud and Abuse Act. Adafruit says it only accessed information publicly available due to a server misconfiguration and frames the reporting as public-interest, responsible disclosure. They’ve paused blogging while considering next steps and will update the community.

Not Every Byte Gets a Vote advocates a disciplined replay surface: only state that can affect future gameplay should influence the replay checksum. It separates authoritative gameplay state from derived caches, observations, and presentation, with inputs recorded on a fixed-tick loop using explicit RNG and initialization. Debug data, caches, and render helpers stay non-authoritative. Replay vs snapshot are related but distinct, and a practical checklist classifies state: if it can change future gameplay, include it in the checksum; if not, keep it out.

Janet is a tiny Lisp-like imperative language with a minimal core (eight instructions: do, def, var, set, if, while, break, fn) and macro support (quote, unquote, quasiquote, splice, upscope). It’s easy to learn, and its standard library fits on one page. Janet compiles to bytecode and ships as a native, statically linked binary, so programs run without Janet. It excels at text parsing via PEGs, offers a strong shell DSL, is embeddable in C and even websites, and features mutable/immutable collections, macros, and compile-time run-time value serialization. Ideal for small CLI tools and scripting.

Muxcard is a credit-card sized computer prototype with ESP32-C3, a 1.54" e-paper display, and NFC. The aim is a true card-thickness (~1 mm) device around ISO7816 specs, capable of wallets, tickets, offline keys, and more. The current build is a DIY flex-PCB approach using kapton tape, copper foil, and manually soldered wires; later prototypes use professional flex PCBs. Core components include ESP32-C3, LIS2DW12 IMU, RC522 NFC, and a 30 mAh ultra-thin LiPo. Sleep ~8 µA. Upcoming work targets durability, battery life, USB-C, microSD, and manufacturability. Sign up for launch at muxcard.com.

Tom Hanks says Toy Story 5 tackles children's screen addiction, with a frog-like tablet called Lilypad that enthralls kids. Hanks, Tim Allen and Joan Cusack return as Woody, Buzz and Jessie, while Greta Lee voices Lilypad. The story resonates with parental worries about screen time and the blue glow of phones. Allen and Cusack note a generational tech divide, citing real-life short attention spans. The movie, releasing later this month, features a Taylor Swift song on its soundtrack and introduces the franchise’s first tech-centered villain.

Open-source CQL is a category-theory–driven language and IDE for transforming data, enabling querying, combining, and migrating databases. Production-ready for single-node in-memory workloads; commercialized by Conexus AI (contact Ryan Wisnesky). It embeds a theorem prover that guarantees correctness and detects data-integrity violations at compile time, preserving data quality with perfect provenance. CQL generalizes SQL with higher-level abstractions (multi-table results via foreign keys), supports rich data integrity constraints, and flexible I/O (JDBC/SQL, CSV) plus visualization. UDFs can be written in Java/JavaScript; stateless, not a DBMS; powered by Kan extensions and ologs.

An enthusiastic DIY project where the author buys a cheap toy robot, disassembles it, and rebuilds it into a kid-friendly, LLM-powered toy. Hardware overhaul uses cardboard, a paper cup chassis, and an FT232H to drive the motor. The software is a local client-server stack: phone as renderer; server handles speech-to-text (Parakeet), memory, and an on-device LLM agent (Gemma via llama.cpp); text-to-speech via Qwen3 TTS Rust. Focus on privacy, low-latency streaming, barge-in, and repairability. Field tests with neighborhood kids produced several robots and renewed DIY enthusiasm.

Jane Street's post introduces strace-ui, a terminal UI that makes strace readable: short IDs for PIDs, formatted structs, hexdumps, interactive filtering, FD tracking, and hostname resolution. It then links this to Bonsai, a reactive UI framework in OCaml, and Bonsai_term for building fast, keyboard-driven TUIs with shared backend/frontend code. With AI tooling (AIDE) and rigorous expect-based tests, the team shows a thriving TUI ecosystem (e.g., proctopus, dissect) and a renaissance of terminal apps. They encourage readers to try installation guides and experiment with LLM-assisted UI development.

Eric Harshbarger’s palindrome page features his work, including the example “E-Z? A man is on... I'm Minos in a maze!” (24 letters/numbers; punctuation ignored; even length, no pivot). Readers can rate palindromes and search by length, rating, pivot, and other criteria. The site explains palindromes (words/phrases reading the same forward and backward when letters/numbers are considered; punctuation/spacing may be altered) and notes Harshbarger has created palindromes since 2008, with copyright 2008–2026.

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.

A sprawling compendium of book dedications, this text stitches together hundreds of personal acknowledgments. Authors honor spouses, children, parents, grandparents, friends, mentors, and even pets, while some address social issues, victims of violence, survivors of illness, and communities in need. The dedications mix intimate, affectionate notes with literary flourishes, appeals to memory and resilience, and occasional humor or profanity, reflecting diverse voices, cultures, and causes.

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).
