ProcInSh is a web-based process inspector for Linux. It lets you explore process space via a browser. Built in Rust with a Node frontend, it can be installed via cargo install procinsh or built from source. It runs locally on http://127.0.0.1:9090 and can be exposed remotely with caution. Prerequisites include Rust, a C compiler, clang with BPF, bpftool, libelf, zlib, and kernel headers; WSL2 support is limited. Build and run: install deps, build, then run procinsh --listen 127.0.0.1:9090.

Cedana offers live migration for CPU and GPU workloads with zero-code changes for Kubernetes and SLURM, boosting performance, cutting costs, and improving reliability. The Tokens to GPUs Calculator turns token volume into GPU needs across models (Llama, gpt-oss, etc) and GPU types (H100, A100, V100, B200), showing base estimates, plausible ranges, and sensitivity analysis. It accounts for model size, token mix, utilization, and input/output costs, and cautions that planning errors can be around 2x while recommending validation on real hardware. Use cases include automation, Elastic Inference, distributed training, HPC, and biotech.

As Mediterranean climates retreat, the American South is emerging as a new olive oil hub. The piece traces olive history from Thomas Jefferson’s failed Southeast experiments to modern Southern producers like Woodpecker Trail Olive Farm in Glennville, Georgia, which makes 15,000–18,000 bottles yearly and earned world-class honors. While California still leads, Texas and Georgia are expanding olive groves, driven by climate-change shifts and a push to diversify U.S. supply (about 5% of 90 million gallons consumed). The industry faces weather risks—frosts, hail, drought—and terroir-driven variation, with growers testing sandy soils and protective microclimates.

A Bluesky post claims someone decompiled the Adobe suite, rebuilt it in Rust, and released it as open source, sparking speculation that software is dead or US copyright laws may change; it links to getartcraft.com/apps.

Minut’s Crowd Detect monitors occupancy in real time to flag unusually high numbers of guests before issues arise. Using passive signals from nearby iOS devices, it alerts you when counts exceed a set limit, helping enforce house rules, avoid parties, and stay compliant with codes and policies across multiple properties. It’s privacy-safe: no cameras or personal data collected. It integrates with PMS/workflow tools (Guesty, Hostaway, Mews). Also includes companion features like noise monitoring, smoking detection, indoor climate, and home alarm.

Lean formalization of the optimality proof for 11-square packing. Reproduces the verified proof with Lean 4.34.1 and pinned sources from EvolvingPrograms; gives the exact optimal side length T as a root u of a polynomial, about 3.8770835900. Construction allows arbitrary orientations, boundary contacts, and disjoint interiors. Includes ElevenSquare and Sqpack Lean modules, verification scripts, and run instructions; credits to EvolvingPrograms, ctjlewis, and contributors.

Playground is an experimental, no-code gaming platform that lets you create custom games in minutes using simple text prompts via a chat-like interface. Choose genres like Trivia, Tower Defense, Racing, or start from scratch, then create, share, and play your own titles. The platform hosts sample games (e.g., Truth Ninja, Polygon Pazer, Octo Pop, Word Cube, Foosball Shootout, Summit Swoop) and supports single-player experiences with various themes. Some content may require subscriptions or be region-restricted. No coding required; your imagination sets the rules.

Timber Frame Tools explains how to make a joiner’s mallet and, crucially, how to set its head angle. The angle isn’t fixed; it depends on how you swing the mallet (elbow/arm for heavy strikes vs. wrist for fine work) and where you grip it. The post walks through constructing the mallet from scraps, including the tenon, stop hole, mortise, handle shaping, leather faces, and finishing. A simple string-pivot method is used to transfer the angle to both faces.

A Tilehurst house features a hand-dug underground network more than 15m below ground, created by civil engineer Tony Deane over two decades with help from his six children. The property has about 1,300 sq ft of tunnels and rooms, a hand-built railway, a rocket-hidden entrance by the pool, a one-tonne lift and two secret doors. It’s for sale at about £300,000, with a 2,500 sq ft workshop, swimming pool and gardens. Planning consent (Dec 2024) allows a new 5,000 sq ft five-bedroom house on the pool site; auction Oct 28-29. Potential uses: storage, fallout shelter, EMP-resistant data centre.

AI agents are transforming software engineering but won't eliminate the need for human seniority. Juniors working with agents must cultivate personal skills—curiosity, questioning, careful reviewing, system architecture sense, algorithmic understanding, token efficiency, mentorship, and collaboration—to grow into Senior roles. The author builds a self-written skill.md to teach herself, emphasizing read-only exploration, planned mutations, and disciplined review to learn from AI without abdicating responsibility. True seniority comes from staying actively involved, mentoring juniors, and ensuring humans stay in the loop; leadership must allow room to learn.

Rust's derive often implies #[inline] on generated trait implementations (Debug, Display, Clone, etc.), as seen when expanding #[derive(Debug)]. Inline is a hint, not a guarantee, and is usually beneficial because these impls are small. But for complex error hierarchies, inlining every derived Debug can produce a lot of code. The author reports that a Rust binary shrank by ~160 KB by preventing inlining for two Debug impls, using a custom macro akin to derive(Debug) but with #[inline(never)]. In many apps, inlining is fine; sometimes avoiding it reduces binary size.

LLMs can compress to cablese—telegraphese with no articles or filler, lowercased, preserving every fact—yielding 40–49% savings in output tokens on major APIs with information fidelity intact across four model families, given a one-sentence cablese instruction. The Telegraph Test compares plaintext, plaintext summary, cablese summary, and decoded cablese; readers and downstream models recover at 0.99–1.10 vs plaintext. Expansion back to plaintext recoups about a third of the savings. Cablese is deterministic and auditable; store scratchpads in cablese for machine use and decode for humans.

AstroHelm is a smartphone app (iOS/Android) that plate-solves the sky to guide you to objects or frame them for photography without a GoTo mount. It uses on-device plate solving for sub-arcminute accuracy (up to 10 arcseconds) and works offline, immune to magnetic interference, and hardware-agnostic with no required subscription. Features: live navigation, highlighted targets, precise pointing, works in light-polluted skies, can guide one device from another, integrates with Stellarium/SkySafari and ASCOM Alpaca/INDI/LX200. Pricing: free with optional one-time upgrades (Plus, Pro) for expanded catalogs and remote control. © 2026 Pacizu LLC.
