NASA recruited former SR-71A staffers to assist with a secret restart of Tail No. 844, moving the jet from Edwards AFB display to a hangar for inspection. Retiree Mike Relja and ex-pilot David Ash discussed the effort, but NASA has not publicly confirmed a return-to-flight program. The 59-year-old airframe lacks spare parts, trained crews, and a working supply chain; engines may be corroded after decades, and many spares were destroyed in 2007. Some propose cannibalizing parts from other museum SR-71s, but feasibility hinges on substantial funding and engineering.

Cloudflare announces it will become a public certificate authority. It has applied to Chrome, Apple, Microsoft, and Mozilla root programs and agreed to acquire an established root from GlobalSign to ensure immediate reach, and plans to issue post-quantum Merkle Tree Certificates (MTCs), with production in early 2027. The move includes ACME-first issuance, renewal automation (RFC 9773 ARI), transparent operations, reproducible builds, and a public issuance dashboard. It will pursue two trust paths: maintaining a broad existing root for old devices while also enabling new roots for PQ readiness, and will act as customer-zero while collaborating with other CAs.

Overview of text classification from bag-of-words to Jev. Jev is a fast, cheap, general-purpose classifier that often rivals GPT-style models on diverse tasks, without task-specific fine-tuning. The article traces methods from bag-of-words (Naive Bayes, logistic regression) to embeddings, RNNs, CNNs, and transformers (BERT, GPT, T5). It explains Jev APIs (Choice for multi-class, Noul for binary/multi-label, Score for ordinal), and shows IMDb results around 96% accuracy. It discusses calibration (RLCD/RLCR), potential to wrap a Jev-like API around BERT/GPT models, clones, and OpenAI’s Decision API, and notes privacy and use-case limits.

When oil prices spike, more money flows to oil producers, but beneficiaries vary by ownership and policy. In the Middle East, governments (e.g., Saudi Arabia) gain as revenues fund public spending. In the U.S. Permian Basin, windfalls go to company owners and shareholders, with reinvestment shaping output. In the North Sea, UK shareholders profit while taxes fund public spending; Norway channels revenue into its sovereign wealth fund; Alaska pays dividends. Russia’s oligarchs and regime benefit under sanctions. In the short run, consumers pay; long run, a shift toward non-fossil energy unfolds.

Ronacher argues Serde’s design creates corner cases and buffering limitations (maps-as-numbers, internally tagged/flattened enums, arbitrary-precision handling, etc.) that are not easy to fix without breaking ecosystem guarantees. He revisits Deser, a Rust serialization library inspired by miniserde that swaps roles: formats drive the type of the next value and push events into a heap-backed sink, enabling no-stack-overflow nesting and streamable IO with layers, adapters, and an extensible data model. It supports JSON variants, YAML/TOML, CBOR/MessagePack, XML, plist, CSV, and more, but omits non-self-describing formats like protobuf. Tradeoffs include runtime overhead and safety concerns, but broader format coverage.

Light pollution is making the night sky 10% brighter each year, erasing darkness and affecting ecosystems and human health. The author recalls sleeping under Oregon’s Dark Sky Places, where Venus, the Milky Way and satellites compete with city glare. With about 80% of people under polluted skies, the piece argues for smarter outdoor lighting and stricter rules—shielding, not excess brightness—along with zoning measures like Flagstaff’s Dark Sky rules and New York’s proposed Dark Skies Protection Act. Darkness should be a shared right.

Corral is a Linux tool that runs a command with a time limit and ensures all spawned processes are terminated when the run ends. It tracks the full process tree via cgroup v2 (enforced mode) or a fallback mode; it is not a security sandbox. Build from source or use prebuilt binaries; requires Linux 5.11+ (5.14+ for enforced). Common options include --wall, --mem, --pids, --max-output, --json, and --cgroup-mode. The README explains how it works and exit codes.

This post describes building a graph-reduction language in C (graphLang) starting from evaluating 1+1 with a binary-tree evaluator, then generalizing to functions, variables, and closures. It introduces a custom memory architecture: an arena- and chunk-based allocator and an environment hash table mapping names to nodes. Functions are represented as closures as first-class values. A stop-the-world mark-and-sweep garbage collector dramatically reduces memory usage (fib), and the author outlines upcoming work on TCO, a lexer/parser, FFI, REPL, and more efficient collectors.

Enigma was the German military’s WWII encryption device. It encoded messages using rotors, a plugboard, and daily settings (Grundstellung, Walzenlage, Ringstellung) that changed each day. Army and air force operators chose from five rotors, navy from eight, with a daily key sheet guiding rotor order and plugboard connections. Keys were pressed to emit Morse-coded lamps; Enigma did not transmit itself. Polish, British, and French cryptanalysts exploited weaknesses in the machine and procedures to decrypt intercepted messages. The material explains the components and how encryption works.

Vermont's Green Mountain Power treats home battery systems as a virtual power plant, the state's largest power source. About 5,500 residents participate, paying $55/month for two batteries via a 10-year lease. The system, often paired with rooftop solar and EVs, is coordinated to cut peak demand and prevent outages, replacing costly peaker plants. GMP's VPP now delivers ~110 MW; the utility aims to erase outages by 2030. Nationally, VPP capacity could reach 160 GW by 2030, offering grid savings but facing regulatory barriers.

UnoDOS is a contract-driven family of GUI operating systems, from an 8088 PC/XT reference to modern bare‑metal pc64 on 64‑bit PCs. The forward repo hmofet/unodos hosts active development; unodos-3-legacy is archived. It bundles a common contract (unodef), a cross‑platform UI (unoui), 3D (uno3d), media (unomedia), networking (unonet), storage, and drivers, plus a hypervisor (unovirt) and a browser/office stack (UnoWord, UnoCalc, UnoShow). Ports span home computers, consoles, SBCs, and phones; builds are platform‑dependent with real hardware validation documented. Prebuilt images and docs describe boot/install and platform status.

livenerf is a long-running, deterministic benchmark to detect whether frontier models degrade after launch. It measures drift in model capability by running a fixed, pre-registered panel daily against a control (Claude Opus 5) using a hermetic harness based on Inspect. The setup pins prompts, CLI, and data; it logs full transcripts and metrics such as accuracy and output tokens. The protocol uses calibration, design, and validation docs, with pre-registered decision rules (two 10-day windows, 99% CI, minimum detectable effect). Results are published over 30 days; aims to isolate model changes from infrastructure noise.

Mercenary Games Explained provides a technical breakdown of Mercenary (C64, 1985) by Paul Woakes. It covers rendering Targ (one building at a time), the 256×256 world with remote locations, and 174 underground rooms. It surveys 64 objects, the flight model and motion records, and SID sound with Benson’s on-screen printer. It summarizes the 51 event scripts, money in BCD, two‑byte log/arithmetics, eight line-draw routines, and the controls, opening sequence, and protection quirks. It notes listing.json data and attribution (CC BY‑SA/MIT).

Galaxy Game, the first coin-operated Spacewar game, debuted in 1971 at Stanford’s Tresidder Union. It ran on a PDP-11/20 with 8K core and an HP 1300A vector display, emulating Spacewar from MIT’s PDP-1 lineage. Despite long lines, the hardware wasn’t profitable; a 1972 revision let one PDP-11 drive multiple consoles. It operated until 1979 when the display processor failed. Restored in 1997, it is now being reanimated at the Interim Computer Museum. The PDP-11 power supply has been rebuilt and the HP displays are being refurbished; you can play it via MAME and support restoration.

Memory suppliers are destroying the consumer market by moving to long-term, large‑volume agreements (LTAs) that prioritize cloud providers over individuals. Micron, Samsung, and SK Hynix are locking in 3–5 year LTAs and allocating 50–70% of output to top customers, shrinking RAM/SSD supply for consumers. This fuels cloud‑infrastructure growth, drives steep price increases for RAM and SSDs, and may reduce volatility but raise the floor for consumer costs for years. NAND may loosen sooner, but DRAM remains tight; policy and Chinese memory players add further uncertainty.
