yggstore is a proof-of-concept for sharded, encrypted storage among friends via Yggdrasil. Files are split into 4 MiB AES-256-GCM chunks, erasure-coded into 4 data + 2 parity shards, and spread so any 4 of 6 shards reconstruct a chunk. Each file's key is in a sealed stub; stubs are exchanged to share items. Nodes run per-machine dashboards with a shared admin-controlled peers.json. Users join via invites; integrity is checked with hashes. Experimental; cryptography not independently reviewed.

An exploration of how processor caches affect performance, with practical C# experiments. Caches are fast but small; memory access dominates timing, not arithmetic. Cache lines of about 64 bytes mean touching every 16 elements touches one line; increasing stride reduces line touches and speeds up loops. The post describes L1/L2 (and sometimes L3) caches, and cache associativity (direct, N‑way, fully). It also covers false sharing on multi‑core CPUs and other hardware quirks, emphasizing measurement and verification for performance tuning.

John of Arderne, a founder of modern surgery and author of De Arte Phisicali et de Cirurgia and Fistula in Ano, is the focus. The Sweden Scroll is a lavish 5.42 m long vellum manuscript—unique in scroll form—likely commissioned by a wealthy London woman circa 1430–1450 and now linked to Queen Philippa in the National Library of Sweden. It contains over 120 marginal figures and four large nude anatomies showing the circulatory, nervous, skeletal systems and viscera, all unlabeled. It marks a medieval-to-Renaissance shift toward explicit anatomy, foreshadowing Vesalius.

OpenWAM is an open framework that unifies video prediction and robot control via a shared causal robot-video backbone and configurable video–action interaction. It uses a 5B video expert and a 2B action expert in a Mixture-of-Transformers to support video-then-action, action-then-video, joint, and decoupled generation, with independently trained dynamics models (IDM and FDM). It enables counterfactual learning (LIBERO-Long-CF) to boost transfer. On LIBERO benchmarks and real bimanual tasks, OpenWAM achieves high success (~97–99%), with video adaptation and local-context dynamics improving performance. The framework provides a common testbed and code.

nanoMuse is an open-source personal agent for every device you own. It runs on Android, iPhone/iPad, Windows/macOS/Linux, and in the browser, with the phone and computer acting as its hands. It keeps working when the app is closed, remembers you, and asks before irreversible actions. Each device runs its own agent; they connect through a relay you can self-host, so data can stay on your network. It supports multiple providers (ChatGPT, Claude, Kimi, etc.) and is GPL-3.0-or-later.

Two unexploded WWII bombs found in Devon on January 14, 2026—one a 50kg device at a Plymouth building site, the other a 250kg bomb aboard a dredger at Exmouth Marina—triggered a high-stakes response by 11EOD and the Royal Navy. The piece follows the crews’ careful fuze assessments, risk calculations, and evacuations of hundreds of homes, with options limited to moving the bombs or detonation at sea. It places the events in a long history of wartime ordnance still surfacing and the evolving tech and procedures to neutralise them.

GSoC 2026 report: modernizing racoon2, the NetBSD/Linux IKE daemon, for L2TP/IPsec and IKEv2 VPNs. Implemented RFC-compliant NAT traversal, robust IKEv1/IKEv2 fragmentation (RFC 7383), NAT-OA payload handling (RFC 3947), and address substitution in NAT-T (RFC 7296). Unified address macros; IPv6 now default and fully supported; policies generated from SA endpoints and peer proposals. Added a self-contained unit-test framework with four tests; updated docs and samples and a consolidated NEWS entry. All changes merged upstream in gsoc2026 branch (PRs 13–39). Remaining: racoon2ctl for graceful connect/disconnect and broader IPv6 end-to-end testing.

Codemode lets the LLM orchestrate complex tasks on the harness side, separate from the execution environment. It runs in a sandbox (QuickJS/WASM) with no network, no FS, limited RAM, and returns structured JSON. It supports concurrent calls, transcript state, and cross-invocation data. It can use image generation and classification APIs and drive MCP servers via a discovery flow, without exposing tools to the LLM. Limitations include MCP quirks (structure, consistency, large binaries) and durability concerns; still, it's a useful, expandable pattern for harness-level orchestration.

SysAdmin1138 announces retirement as ServerFault moderator after 15 years, dating back to the 2011 elections. He recalls early fractious times, intercultural flame wars between Russian-speaking and British users, and the need for moderator intervention. He notes a long traffic decline since 2013, now 2–3 questions daily, with a spam-heavy moderation queue. He credits improved StackExchange anti-spam measures and says he will step down at year-end, leaving the community to decide whether to replace him.

treg is OpenRouter for agent tools—a registry and proxy that lets agents call external endpoints, CLIs, and skills with a single token. It stores or proxies credentials, so secrets never reach the agent. It supports own-team keys, provider keys, or anonymous calls (paid via team balance). You can self-host treg or use treg.to, with a searchable catalog, balance and top-up, health checks, and an audit log. It is designed for self-contained tool sharing, OAuth/connect flows, CLI integrations, and plugins for Claude and MiniMax.

Reddit bans for posting links to GitHub projects; the author experiments with tactics to appear legitimate. They note that posts are deleted and accounts banned unless you first post as a regular user: wait days, leave comments, and build karma. Posts longer than two paragraphs and well-formatted are flagged as AI-generated and banned; adding mistakes helps. Even after creating own community, bans occur. Other users advise 1k karma and using the mobile app. After reaching 1k karma, posting a link is sent to manual review, but the account is banned within an hour, preventing exposure of the projects.

Óscar Toledo G. recalls using a Z80-based homebrew PC in 1993 to dial into La Cueva BBS in Mexico via a 2400 baud RS-232 Hayes modem, building a serial terminal and implementing ANSI escape sequences. He captured a 64K log of a La Cueva session (Feb 11, 1993, 9:30–9:47pm) in CUEVA.TXT, then recreated the data in JavaScript/jsTerm for replay and shared updated notes in 2026, including a list of 1993 BBS numbers (noting Nopal BBS and La Cueva de Atari). The era faded by 1994–95.

Microsoft reportedly won exclusive GTA VI streaming rights for Xbox Cloud Gaming at launch, meaning GTA VI can only be streamed via Xbox Cloud Gaming initially. The deal could help Microsoft market Cloud Gaming to PC players who don’t own a console, though the duration of exclusivity isn’t clear. The move coincides with November changes to Xbox Cloud Gaming, including reduced streaming hours (15h Ultimate, 10h Premium, 5h Essential) and a new pay‑as‑you‑go option for GTA VI. Xbox teased Project Helix—a next‑gen family of devices developed with AMD and broader partnerships.

Jev-Driven SRE Diagnosis presents a pipeline that collects cluster state (Kubernetes objects, events, logs, metrics), summarizes by component, and lets Jev pick likely origins and evidence, forming a diagnosis report. Across 21 SREGym-Lite faults, it passed 80/105 diagnoses (76.2%) with a 14.6s median time and about $0.15 per diagnosis. Jev is faster and cheaper than LLM agents but less flexible. A case on webhook limits caused OOM shows how signals guide the choice. Failures show Jev can pick wrong clues or miss signals from the collector. Conclusion: promising first-line tool; future work includes multi-service, evolving faults and hybrid models.

An exposé of Robert X. Cringely and the Mineserver Kickstarter, tracing decades of bold claims and repeated lies that led to missed shipping promises, evasive updates, and a pivot to grandiose schemes (Eldorado Space). It catalogs false claims (a supposed buyout of Starfighters with a Photoshop image) and escalating hype, concluding that dishonesty erodes credibility and wrecks a journalist’s career.
