The Long Reply

David Friedman reflects on why a viral Threads post about Noah’s trees resonated, noting how engagement drives reach and the charm of long timescales. A five-year reply is trivial beside Noah’s decades-long projects (Everyday, Lumberland). He cites other long-reply phenomena—Tim Chambers’s yearly Twitter replies, a decade of updates, a 20-year Bluesky note, and a 25-year birthday letter opened after 25 years. He considers replying to his oldest unanswered emails and invites readers to share their own longest lag before replying.

Amateur armed with ChatGPT solves an Erdős problem

Amateur Liam Price, 23, using ChatGPT Pro, reportedly solved a 60-year Erdős problem on primitive sets by prompting GPT-5.4 Pro to produce a solution. The problem centers on the Erdős sum and the conjectured lower bound of 1 for infinite primitive sets; prior work by Lichtman set the maximum near 1.6 for finite sets. Tao and Lichtman say the AI found a novel method, using a known formula in a new context; the raw AI output required human interpretation. They have streamlined the proof and see potential broader applications in number theory.

Europe to burned American scientists: We'll take you in

EU and member states are mobilizing to attract U.S.-based researchers threatened by Trump’s crackdown on science. The Commission vows to enshrine freedom of scientific research in EU law and boost ERC funding, up to €4.5 million per relocating researcher. Universities and cities are launching recruitment schemes and support hubs—Aix-Marseille’s Safe Space for Science; VUB visa welcome center; Karolinska outreach; Berlin funds; Catalonia’s €30 million Talent Bridge; with similar efforts in Spain, Belgium, and beyond—to reverse the brain drain and defend academic freedom.

Flickr: The First and Last Great Photo Platform

Flickr, launched in 2004, remains a simple, group‑driven photo‑sharing home for enthusiasts. Since SmugMug’s 2018 takeover, it avoids trendy pivots and emphasizes stability, privacy, and an ad‑free Pro plan with unlimited full‑resolution storage, advanced stats, and perks. Its strengths include rich metadata, robust organization (Sets/Galleries), and active groups; drawbacks are occasional outages, aging features, and a high Pro price (~$82/yr). The piece, a rebuttal to a 2026 critique, argues Flickr Pro is still worth it for serious photographers seeking a durable, community‑focused platform.

Agents Aren't Coworkers, Embed Them in Your Software

The piece argues agents should be embedded in software, not run as external copilots. To reduce noise, use agentic patterns—CLI, declarative specs, and reconciliation loops—that let agents converge to a target state rather than long chats. Feldera’s approach pairs an incremental database engine with these ideas: a CLI, SQL-described computations, and a desired-state control plane. It also uses change data capture (CDC) so agents get precise, event-driven updates instead of costly re-scans. A fraud-detection demo shows agents reacting to streaming changes; demos are on GitHub.

Math Is Hard

The piece explains how BSD kernels fixed a SIGFPE loop on VAX by distinguishing traps from faults and realizing the PC could point to the faulty instruction. Miod Vallat and colleagues implemented a skip_opcode routine to advance past the faulting instruction by disassembling it, since VAX faults don’t provide the next-instruction address. The fix, initially tied to debugging code, was reworked to be debugger-independent and later improved to handle two-byte opcodes. It eventually reached NetBSD (and later OpenBSD contexts), addressing long-standing VAX arithmetic-exception issues and related BSD signal handling quirks.

USB Cheat Sheet

USB Cheat Sheet catalogs generations, naming conventions, speeds, encoding, lanes, and real-world throughput. It maps marketing names (USB 1.1/2.0/3.x/USB4) to signal rates (Mbps/MiB/s), lane counts, and cable/wire configurations (4, 8, or 12 wires). It explains Gen A×B nomenclature, encoding schemes (8b/10b for some gen, 128b/132b for USB4/Gen2), and their effective/two-way rates. It covers USB-C’s two-lane capability, power delivery and charging (from 5V up to 240W in PD 3.1), and lists a USB standards timeline with references.

The Joy of Folding Bikes

Korny extols folding bikes, especially Brompton, as a game changer for commuting. After using Boris Bikes, he bought a Brompton (current prices from ~£1400) and added puncture-resistant Schwalbe Marathon Plus tyres. The bike is about 12 kg, fits in trains, car boots, offices, or cafes, and can be carried in one hand for short hops. It’s reliable (11+ years with minimal issues) and mitigates theft by letting him avoid street-locking. Economics favor it: £10 daily station parking translates to ~28 weeks payback. He endorses Cycle Streets for safer routes and sensible riding for city life.

How Hard Is It to Open a File?

Opening a file securely is hard when a high-privilege process acts on behalf of a low-privilege one. Path-based checks are fragile: subpaths can escape directories, symlinks can redirect, and TOCTOU races let attackers swap files during validation. The safe remedy is using file descriptors as stable references to inodes (pins) via O_PATH, openat, and O_NOFOLLOW, performing traversal relative to a dirfd, and avoiding absolute path arguments to privileged calls. Libraries that expect paths (GLib, GIO, Rust) worsen risk. Flatpak’s CVE-2026-34078 showed the need to replace path strings with fds across the call chain.

The AI Industry Is Discovering That the Public Hates It

The New Republic argues AI faces a growing public backlash, underscored by violence against industry figures and cross-cutting mistrust. Stanford’s AI Index shows experts optimistic about jobs and the economy, but the public expects job losses and rising inequality. Gen Z sentiment toward AI has grown more negative. Critics fault industry messaging that casts AI as existential peril or unstoppable progress, while pilots show little productivity gain. OpenAI and Microsoft proposals lack independent accountability. The piece calls for transparent regulation and real community input to rebuild trust.

The traffic could come from malware, a browser plug-in, or automated scripts. If sharing a network, contact the administrator; another device on the same IP may cause the issue.

The Stanford Freshmen Who Want to Rule the World

The Atlantic investigates Stanford’s 'inside Stanford'—a culture in which Silicon Valley investors recruit and fund 18‑ and 19‑year‑olds, turning dorm rooms into launch pads for tomorrow’s tech giants. Pre‑idea funding, secret clubs, lavish dinners, and campus talent scouts steer students toward startups, often rewarding networking over genuine invention. While Stanford fuels enormous wealth and innovation (StartX, on-campus companies, famous alums), critics warn the system prizes hype and speed over ethics, citing fraud cases (Holmes, Clinkle) and a myth of meritocracy that masks influence and luck.

North American Millets Alliance(2023)

North American Millets Alliance (NAMA) promotes millets as climate-resilient, nutritious grains across the US, Canada, and Mexico. Millets are drought- and heat-tolerant, generally nutrient- and fiber-rich, gluten-free, with a low glycemic index and diverse flavors; some tolerate waterlogging or shade. They serve food and non-food uses (forage, cover crops, birdseed, biofuel). NAMA advocates for growers, processors, marketers, and consumers, and pursues education and projects. Activities include millet news, a proso grain standards proposal, a Millet of the Month calendar, and community-building; past efforts include 2023 webinars and the International Millets Conference.
