On Apple Silicon M4, using parking_lot::RwLock in a Rust LRU tensor cache, read locks were about 5× slower than writes for a read-heavy get operation. The cost isn’t just a single thread read; each read increments an atomic counter, causing cache-line ping-pong across cores. The write lock, while exclusive, avoids this contention and often ends up faster. Takeaways: beware very short critical sections; profile hardware with perf; consider sharding or alternative locking; read-heavy paths may still benefit from Mutex or simpler locks depending on read size.

Alan Pope tests his riscv64 snap Notepad Next by running Ubuntu RV64 in a QEMU VM on a ThinkPad since he has no RISC-V hardware. Ubuntu RVA20 is available in 24.04; RVA23 (with Vector and Hypervisor) was ratified in 2024, but RVA23 boards aren’t available yet. He installs a headless server in QEMU, then adds a desktop and confirms the snap launches, albeit slowly due to CPU emulation. He plans a snap-by-snap audit for riscv64 support and notes RVA23 hardware expected around spring 2026; for now, QEMU suffices for testing.

Remote Control lets you continue a Claude Code session from another device while the session runs on your machine. Requires Pro/Max; no API keys. Start a new session or carry over an existing one with claude remote-control, which provides a URL and QR code to connect from another device. Optional /config enables auto-start for all sessions. Traffic uses outbound HTTPS/TLS via the Anthropic API. Limitations: one remote session at a time; terminal must stay open; possible timeout after network outage. It runs locally, unlike Claude Code on the web.

Denmark’s Ministry for Digitalisation plans to ditch Microsoft in favor of LibreOffice to cut reliance on US tech and avoid Windows 10 support costs. Minister Caroline Stage Olsen says over half the ministry’s staff will switch next month with a full open-source transition by year-end; the ministry could revert to Microsoft if needed. The move is part of a broader push for digital sovereignty, following Copenhagen and Aarhus, and reflecting Schleswig-Holstein’s German shift to open-source and Linux.

Part 1 traces the history of binary decompilation and the persistent control-flow structuring problem. It starts with Cristina Cifuentes’ 1994 work—recover CFGs, lift types, and structure graphs into high-level code via pattern matching—and shows how goto choices affect output quality. It surveys decompilers (IDA/Hex-Rays, Reko, Snowman, Ghidra, Binary Ninja) and milestones (TIE 2011, Phoenix 2013; No More Gotos 2015). Progress is slow; open-source options exist, but structuring remains challenging. Part 2 will cover modern structuring techniques and future directions.

English harbors vast multi-word expressions (MWEs) that naming/space-based dictionaries miss. Traditional dictionaries cover only about 3% of top MWEs; Wiktionary boosts coverage to ~30% but gaps remain, especially for obscure or opaque phrases. Of roughly 250 billion possible two-word combos, about 15% are plausible, yielding ~30 billion sensible pairs; many carry conceptual weight beyond their parts (e.g., boiling water, red tape). MWEs vary by origin and opacity (transparent, semi-opaque, opaque; phrasal verbs, technical terms, named entities). The article argues for rethinking word games and dictionary design and notes a companion piece on a 1.9M-term network.

Scheme-langserver is a Language Server Protocol implementation for Scheme that adds code editing features such as top-level and local identifier completion, goto definition, hover, references, and document symbols. It performs static analysis based on R6RS/R7RS/S7 and supports cross-file indexing, type inference, and integration with the Akku package manager. It has been tested with Chez Scheme (9.4/9.5) and aims to support more features like autocomplete and diagnostics; the author notes many bugs and ongoing development and references a related paper/book.

Claim: a long-standing, region-specific Meta network fault in Boca Raton/Miami affects the MNA CDN and Latin American traffic. Symptoms: 10–60% packet loss and data corruption at the interface, not shown by typical monitoring, likely due to a faulty interface/hardware in a bundle and possibly BGP/OSPF/IGP issues. Repro steps: identify affected MNA cluster IPs, ping large payloads, test routes to observe losses on a particular path; fix by isolating the faulty port or hardware. The author criticizes Meta support, notes prior fixes after escalation, and offers help via [email protected]; issue ~7 months old.

The post argues AI coding agents suffer from noisy context windows polluted by build logs and non-essential output. It uses a TypeScript monorepo with Turbo to illustrate pruning output (disable update notifications, configure .claude/settings.json), and trimming logs with techniques like tail, plus reducing noise via NO_COLOR and CI=true. It also suggests trying LLM=true and playfully hints at HUM AN=true to optimize for agent-driven coding. The aim is Win-Win-Win: fewer tokens burned, cleaner context, and lower energy use as agents increasingly code.

shouldhavebought.com is a satirical regret calculator that mocks missed profits. It lets users pick assets (BTC, ETH, SOL, DOGE, NVDA, GLD), enter buy/sell dates, and computes a 'Global Pain Index' and 'Total Capital Saved' to quantify losses. It encourages publicly sharing regrets via a generated URL and features a 'Wall of Shame' and a 'Survivors Club' sidebar ad. The README states the aim is not to teach investing but to make you feel every cent you lost, presenting regret as the site's purpose.

An excerpt from Roger’s Bacon Secretorum presenting Japanese death poems (jisei) from haiku poets, part 3. The piece notes death-awareness pervades Japanese culture and many poets wrote dying odes, many translated here for the first time. It presents 29 death poems, each with the poet’s name, death date, age, and a line or two of the verse, plus brief biographical or contextual notes (samurai, Zen, Basho, famous episodes like the 47 ronin). The collection showcases seasonal imagery and meditative reflections on impermanence and mortality.

Argues India's sovereign AI push via Sarvam AI’s Indus (105B parameter) is a branding exercise with opaque benchmarks and heavy government subsidies ($41M) and a system prompt that injects national pride while sanitizing history (e.g., 2002 Gujarat riots). The piece questions whether full-stack pretraining under Nvidia guidance actually grants sovereignty, noting alignment is embedded in prompts rather than weights. It advocates building on open, proven models (LLaMA, Qwen) with dedicated Indian-language fine-tuning, transparent data, training code, and reproducible benchmarks. Real sovereignty, it concludes, comes from genuine open-source contributions and verifiable performance, not marketing claims.

Context Mode is an MCP server that sits between Claude Code and external tools to compress large outputs before they enter the context window. It reduces 100+ KB outputs to a few KB (e.g., 315 KB → 5.4 KB; 98–99% saved) by sandboxing tool executions and only passing summaries to the model. It provides batch_execute, execute, execute_file, index/search (SQLite FTS5 with BM25), fetch_and_index, and a stats feed; supports 10 runtimes, automatic Bun detection, and credential passthrough. It also offers subagent routing to prefer batching and follow-up searches. Install via /plugin marketplace add mksglu/claude-context-mode.

Georgian wine spans about 8,000 years of history, at Europe–Asia’s crossroads, blending modern methods with ancient traditions. The standout is qvevri fermentation and aging in clay vessels—UNESCO recognized this Intangible Cultural Heritage in 2013. Amber wines, made from white grapes in contact with skins, are a distinctive category with introductory, full-on, and amber‑oak styles. Georgia has around 500 indigenous varieties (45 used commercially; ~75% white, 25% black). Notable whites include Rkatsiteli and Tsitska; blacks include Saperavi. Main regions Kakheti, Imereti, Kartli, and Racha; nearly 2,000 wineries. GAUMARJOS! Lasha Tsatava, DipWSET, champions Georgian wine.

Fry’s Electronics was a large computer-store chain started in 1985 from the Fry family grocery business, peaking at 34 stores and aiming to be an IKEA-like destination for PC parts. It suffered from poor customer service, slow online adoption, and competition from online retailers. In 2008, VP Ausaf Siddiqui embezzled about $65–87 million, leading to lawsuits and his 2011 prison sentence, though the chain endured. By moving to consignment, suppliers balked and shelves emptied. It began closing in 2019; the last stores and online shop closed Feb 24, 2021 (assets liquidated April 2).
