Robert C. "Uncle Bob" Martin — Clean Code author, coding since the late 1960s — says he no longer reads the code his AI agents write. Instead he constrains the agents and reviews a layered test pipeline. Here's exactly what that pipeline looks like, and where it might not generalize.
Peter Yang released /no-ai-slop on July 22, 2026 — an open-source skill for Claude and similar tools that targets over 20 repetitive AI writing patterns (fake-profound closers, binary contrasts, throat-clearing openers) while explaining every edit and preserving your voice. It hit nearly 1,000 GitHub stars within a day. Here's how the skill works and how to install it.
A 92-second Shanghai WAIC clip shows iFlytek's Tongchuang AI Blackboard graphing a handwritten equation, recognizing a rough sketch, and producing a rotatable 3D geometry model. explainx.ai embeds the full video, verifies the product and deployment claims, and separates the booth demo from the viral claim that this is already every classroom's new blackboard.
Cognition, the company behind Devin, announced on July 23, 2026 that it has acquired The Interaction Company of California, makers of Poke — a texting assistant that lives inside iMessage. It isn't a pivot away from enterprise coding; it's a bet that "always-on cloud agents" is one architecture, not two.
Fields Medalist Terence Tao shared a ChatGPT conversation working through an alternate factorization of the Jacobian conjecture counterexample, and it became one of the most discussed AI-and-math threads of 2026 — 665+ points on Hacker News. The math is dense, but the real story is about prompting technique, domain expertise, and what "AI as a colleague" actually looks like in practice.
The Little Tech Association — almost 200 companies including Proton and Y Combinator — sent letters to Trump, Lutnick, and Kratsios on July 22, 2026, warning that banning Chinese open-weight models like Kimi would kill startups without stopping proliferation. Here's what the letter asks for, why it landed now, and what actually happens to a startup's stack if enforcement follows through.
Anthropic opened Claude Security to public beta for Claude Enterprise customers — a tool that scans code for vulnerabilities, runs an adversarial verification pass to cut false positives, and proposes targeted patches for human review. A companion Claude Code plugin keeps scanning inside your existing environment. Here's what it does and how it differs from traditional scanners.
A Nikkei Asia investigation found that Alphabet, Microsoft, Amazon, Meta, and Oracle are carrying an estimated $1.65 trillion in debt that never shows up on their balance sheets — more than the $1.35 trillion they officially report. Here is what the special-purpose-vehicle accounting actually means, where the Enron comparison holds up, and where it breaks down.
Marcel Rød open-sourced GigaToken, a drop-in-replacement tokenizer claiming gigabytes-per-second throughput and up to 1000x faster encoding than HuggingFace Tokenizers on the same hardware — nearly 1,300 GitHub stars within a day. The gains come from SIMD pretokenization and aggressive caching, and matter more for pretraining data pipelines and time-to-first-token than most people assume.
Augmental began public US sales of its MouthPad on July 22, 2026 — a custom-fit mouthpiece that translates tongue movements and head tilts into cursor control, clicks, and scrolls over Bluetooth. Originally built for people with mobility impairments like quadriplegia, users now report speeds rivaling brain-computer interfaces. Here's how it works and what it costs.
Cursor launched Router on July 22, 2026 — an intelligent model router that analyzes each coding request and picks the right model automatically, trained on over 600,000 live requests. Early access customers saw no quality drop-off at 60% lower cost than routing everything to Opus 4.8. Here's how it works, what admins control, and what it means for the model-picking problem.
OpenAI's Tibo Sottiaux says tomorrow is "feeling codexy," triggering guesses about a new model, Linux support, voice, UI changes, and another quota reset. explainx.ai separates the one confirmed announcement from community theories and maps the product signals that will tell us what actually shipped.
Historian Benjamin Breen used Claude Code and GPT-5.6 to build the Book Prize Index — a free, semantic-search discovery tool covering roughly 6,500 titles that won or were shortlisted for major nonfiction prizes. It hit the Hacker News front page, drew genuine praise for its usefulness, and one pointed critique: does using AI to build a quality-focused tool undermine its own premise?
Black Forest Labs announced FLUX 3 on July 23, 2026 — a multimodal model jointly trained on images, video, audio, and action prediction. Its robotics offshoot, FLUX-mimic, is already being tested inside Audi factories. Here's the actual bet behind the announcement, what's shipping today versus later, and how to read BFL's own preliminary benchmark numbers.
Substack integrated Pangram's AI detection on July 21, 2026, scanning content over 100 words published since that date and showing an estimated human/AI-assisted/AI-generated split. CEO Chris Best says it's meant to stop the platform from becoming "like LinkedIn." Writers are split between cheering it as validation and worrying about false positives.
White House science director Michael Kratsios says Moonshot AI ran a sophisticated internal platform to distill Claude Fable 5 for Kimi K3, using restricted Nvidia chips routed through Thailand. Treasury Secretary Scott Bessent floated sanctions. Skeptics note K3 testing predated Fable's release. Here's the claim, the timeline problem, and what distillation actually means.
Simon Willison's "SVG of a pelican riding a bicycle" prompt has become AI's most famous informal benchmark, and the obvious suspicion is that labs quietly train on it. Dylan Castillo tested the hypothesis directly — generating 1,008 SVGs across 8 animals x 6 vehicles x 7 models and running a difficulty-adjusted regression. The result: no statistically significant pelican-specific or bicycle-specific boost at any lab.
DARPA and the US Air Force flew standard F-16s under AI control at Eglin Air Force Base using the VENOM Autonomy Kit — a flip-a-switch toggle between human and machine flight, not an unmanned jet. Here's what the AIR program actually validated, and what the human-on-the-loop safety debate misses.
A 2022 Hugging Face/BigScience project called Petals — run large language models at home, BitTorrent-style — hit the Hacker News front page again in 2026, reigniting a debate about whether peer-to-peer LLM inference is finally viable now that models are smaller, quantization is better, and newer projects like Mesh LLM and AI Horde have taken different approaches to the same problem.
