NanoTDB – Golang Append-Only Time Series DB

NanoTDB is a tiny, embedded append-only time-series database for resource-constrained hardware (e.g., Raspberry Pi, edge IoT). It stores all data as plain files under a root directory with no runtime dependencies. The Engine handles multiple named databases, accepts line-protocol writes, and guarantees monotonic timestamps. Data is kept in three layers per DB: WAL, catalog.json, and partitioned data-*.dat files; pages are compressed (S2). It supports replay on startup, range queries, rollups, and per-database retention/partitioning. It provides a small HTTP API and a CLI (nanocli).

Welcome to the Strip Mining Era of OSS Security

AI-powered scanners are strip-mining OSS, dramatically increasing vulnerability finds. Metabase reports a surge from ~10 monthly to ~10 weekly disclosures, many legit. Some vendors may go closed source as issues proliferate. For OSS maintainers and users, expect a rough summer: vulnerabilities will be rapidly disclosed, and reactive fixes will dominate. Best practices: upgrade dependencies constantly, monitor/pin OSS, apply defense-in-depth, boost logging/observability, and enforce least privilege. Short term pain, but the long-term effect should be more secure code as scanning becomes routine.

Where's Ed: Anthropic Told Court $5B but Public $19B

Davi Ottenheimer’s Where’s Ed critiques Anthropic’s financial storytelling. In a court filing, Anthropic CFO Krishna Rao swore total revenue to date exceeded $5B as of March 9, 2026, yet the company publicly touted annualized revenue climbing to $19B by March 3, 2026. The piece argues ARR is not actual revenue; summing monthly implied revenues from ARR yields about $6.66B in cumulative revenue, well above $5B. The discrepancy suggests inflated inputs feeding valuations and press coverage, possibly by counting unearned contract value as revenue.

Overseas fakers using AI videos to push a narrative of UK decline, BBC finds

BBC Panorama and Top Comment reveal anti-immigration AI videos on Facebook/Instagram created by overseas actors (Sri Lanka, US, Europe, Vietnam, Maldives, Iran, UAE) using fake UK personas. The “Great British People” page from Yorkshire has 1.3 million views, depicting Britain in decline and Muslim immigration. These interconnected accounts monetize via ads, with some linked to state-backed or disinformation-for-hire networks. Experts warn AI fakes distort trust; London and Meta call for labeling and tighter action. Some UK-based participants coordinate with overseas partners; owners could not be reached. Panorama airs soon.

Steve Jobs Next Computer: His Forgotten Exile Years

IEEE Spectrum profiles Steve Jobs' NeXT years (1985–1997) and Pixar influence, arguing the 'wilderness' period was crucial to Apple's later success. The book Steve Jobs in Exile by Geoffrey Cain shows Jobs' maturation—improving discipline, learning to balance hardware-software integration, and recognizing software's central role via NeXT's object-oriented programming and early app concepts. NeXT failed commercially, but its tech underpinned today's Apple OS and devices; Pixar also became a breakthrough under his leadership. The piece also touches Apple's CEO transition and AI trends shaping hardware-centric future.

O(x)Caml in Space

Thomas Gazagnaire reports Borealis, a pure-OCaml CCSDS protocol stack booted in low Earth orbit on DPhi Space ClusterGate-2, delivering end-to-end encrypted, post-quantum authenticated commands and telemetry with OTAR. It runs as a daemon on hosted payloads; the ground link uses a delay-tolerant filesystem, with BPSec wrapping bundles. OxCaml reduces per-packet latency from 29 ns to 9 ns and eliminates GC pressure on the hot path. The stack emphasizes memory-safe OCaml, typed codecs, GADTs for state machines, and robust interop tests. Next: scaling to a fleet with signed updates and attestation.

Geography is four-dimensional

Geography is four-dimensional: places change with time, so opinions about them are bound to when you experienced them. Descriptions from 1980, 1999, or 2002 may feel outdated now. You can only know a place as it was at a moment. The piece uses anecdotes about Indian values, LA, and China to show how identities and reputations evolve, and how national labels (like American) drift across eras.

Building ML framework with Rust and Category Theory

Category Theory for Tiny ML in Rust is a public, working-draft book that uses category theory to design a tiny ML pipeline in Rust. Coauthors Hamze Ghalebi and Farzad Jafarranmani. It treats category theory as an engineering tool: domain objects are Rust types, morphisms are typed transformations, composition as program structure, training as state transformations. Not final; chapters and examples may evolve. Public source: github.com/hghalebi/category_theory_transformer_rs; open-access book: hghalebi.github.io/category_theory_transformer_rs. Public workshop via AI Reading Club. Reuse terms require written permission for large-scale organizational use.

Coldkey – Post-quantum age key generation and paper backup tool

coldkey is a Go-based tool that generates post-quantum age keys (ML-KEM-768 + X25519) and creates printable HTML paper backups with QR codes. Backups are designed to survive loss of digital copies; the HTML includes metadata, raw key text, and a SHA-256 checksum for verification. It supports interactive mode and commands to generate or back up keys, and can be used via Homebrew, Go install, or Docker. Output is written to ./output/. Security-focused defaults include container hardening and memory zeroing; large keys are split across multiple QR codes with a framing protocol.

Solar-based sleep patterns compared to modern norms

The post argues that the classic eight-hour, uninterrupted sleep is a modern invention tied to 9–5 schedules. Historically, people slept in two phases aligned with daylight and seasons: in summer a siesta followed by late-night activity, then a shorter night; in winter a wakeful interval in the middle of the night. Greece still follows a split day with a midday break and an evening work period. The author laments artificial lighting and rigid schedules, praising the siesta as a superior, natural rhythm worth preserving.

reCAPTCHA Mobile Verification Is Bringing the Play Integrity API to Desktops

Discussion argues that reCAPTCHA Mobile Verification is extending Google's Play Integrity API (and Apple's App Attest) to web and desktop environments via hardware attestation, possibly through Privacy Pass. This shift would increasingly require Apple/Google-certified devices to pass CAPTCHAs, risking lockouts for non-Apple/Google hardware and open OS like GrapheneOS. Proponents warn it reduces fraud but critics view it as anti-competitive, consolidating control over the web and enforcing a Google/Apple duopoly. EU/regulatory debates and potential lawsuits are noted, alongside calls for alternatives.

Details of the Daring Airdrop at Tristan Da Cunha

UK government conducted an unprecedented 9 May 2026 airdrop to Tristan da Cunha to aid hantavirus outbreak on the MV Hondius. An RAF A400M, refueled by a Voyager tanker, delivered six-paratrooper British Army Pathfinders and two medical specialists to the settlement, dropping from 7,000 ft near the Back Fence and the 9-hole golf course. About 3.3 tonnes of medical supplies were dropped in three passes at the Patches; medics then assisted Tristan’s hospital, keeping the patient stable. Islanders welcomed the team; governor and officials hailed the operation as historic and pledged follow-up support.

How Claude Code works in large codebases

Claude Code scales by navigating live codebases locally, avoiding stale embeddings. It runs without a central index; each developer’s instance reads the repo with CLAUDE.md context files and an extensible harness (hooks, skills, plugins, MCP servers) plus LSPs and subagents. Key patterns for large deployments: lean, directory-layered CLAUDE.md; initialize in subdirectories; per-subdirectory test/lint commands; noise-reducing ignore rules; and use of LSP for symbol-level navigation and MCP for internal tools. Three patterns emerge: make codebase navigable, modular harness layering, and clear ownership/governance. Adoption needs dedicated infra and cross-functional teams.

Access to frontier AI will soon be limited by economic and security constraints

Frontier AI access is likely to become scarce and selective due to security concerns, high compute costs, and looming government controls. Mythos-style capabilities are already restricted to a few defenders or select firms, and policy may push further toward tiered, restricted access. Distillation, IP protection, and geopolitical tensions threaten broad diffusion. The author foresees a new equilibrium where access is gated, unevenly distributed, and outwardly limited to trusted players. Solutions proposed: improve safety and resilience, massively expand datacenters, and trade compute capacity for access to avert a two-tier AI world.
