An exploration of a simple 1D moving-average blur shows it can be reversed if boundary values are known. A right-aligned window lets the original pixels be computed from blurred outputs iteratively, enabling full reconstruction of the image. Extending to 2D or multiple passes adds quantization noise and makes recovery harder, but information can still leak. By biasing the average toward the current pixel (a weight B), one can create adversarial blurs that preserve retrievable detail—through lossy JPEG storage; the Venus reconstruction illustrates the effect.

A JWST-confirmed galaxy MoM-z14, at z_spec = 14.44, is the most distant bright source yet (M_UV ≈ −20.2). It is ultra-compact (re ≈ 74 pc) but elongated, with a steep UV slope (β ≈ −2.5) and negligible dust, indicating a young stellar population. Redshift is confirmed by a sharp Lyman-α break and five rest-UV lines; high equivalent widths imply rising star formation. The environment may be partially ionized. High [N/C] > 1 hints globular-cluster–like abundance patterns and possible formation of massive early stars, linking to ancient Milky Way stars.

Argues that communities are non-fungible, unlike fungible assets; treating communities as interchangeable when platforms migrate or cities redevelop ignores the unique, time-bound web of relationships that give a community's value. Drawing on Jane Jacobs vs Robert Moses, Dunbar's social layers, and examples like LiveJournal, Vine, and modern "new town syndrome," the piece shows that communities decay when the platform dies, not migrate, because social capital and ambient trust are irreproducible. Building "new" communities from scratch is insufficient; disruption imposes irreparable costs; communities are the product, not the container.

signy is a library for generating signed URLs on embedded devices using asymmetric cryptography to grant time-limited access to private resources. A device creates a signed URL that a capable system can use to download the resource; the server must verify it. If using Golioth, upload the CA certificates to your project. Signing uses the PSA Crypto API; private keys are created or imported via PSA, and a signed certificate with the public key is passed to signy. URL format: BASEURL?nb=NOTBEFORE&na=NOTAFTER&cert=CERTIFICATE&sig=SIGNATURE; NOTBEFORE/NOTAFTER are Unix times; CERTIFICATE is base64 URL-encoded; SIGNATURE covers the portion before &sig=. Zephyr/ESP-IDF integration notes.

To mark the 20th anniversary of Steve Jobs’ 2005 Stanford commencement address, the Steve Jobs Archive released an enhanced video of the talk—one of the most influential addresses, watched 120M+ times. Jobs, a college dropout, urged graduates to stay hungry and stay foolish; the piece combined humanist themes with a tech founder's perspective. Initially not the top pick; Jon Stewart and Arnold Schwarzenegger were considered. He largely wrote it himself—with Laurene’s help, emailing ideas to himself—delivering a 15-minute, verbatim speech in Stanford Stadium while dressed in jeans, a black shirt, and Birkenstocks. The archive includes transcripts and related artifacts.

Update on Flirt development: the Git native backend is largely implemented, though not feature-complete. It stores review data in a Git repo via a custom ref to a commit whose tree holds spirit.json, avoiding git-notes issues and preserving history. Core features planned/considered include per-commit comments, optional line-range comments, commit-message/headers comments, comment threads, marking files viewed, marking threads resolved, and verdicts. Thread materialization and a notion of thread relocation are being designed. Next milestones: finish two more backends (GitHub and the mailing list) by end of March and possible alpha of the native backend; feedback welcome.

Humorous 23‑point survival guide to living in a very snowy place: plan for outages, read manuals, stock batteries, food, water, and warm clothing; snow becomes denser with time and shoveling requires grit; a neighbor with a snowplow helps; roof snow may need removal; stay dry with waterproof layers and changing pants; don’t run generators indoors and winterize/position them safely; manage water and toilet flushing during outages; morale can sag—reading may not satisfy, you’ll crave Animal Crossing; expect another storm and plan for potential evacuation.

Google Search now provides a simpler way to remove non-consensual explicit images. Users can report multiple images at once via a quick form, by clicking the three dots on a result and choosing “It shows a sexual image of me.” They can opt in to safeguards that proactively filter out similar results. After submitting, requests can be tracked in the “Results about you” hub, with email updates and links to support resources. The rollout starts in most countries and will expand to more regions, aiming to reduce the burden on victims and improve online safety.

Three-stage model of a training input pipeline: CPU-side prefetch queue (often pinned memory), host-to-device transfer into a GPU VRAM backlog, and GPU compute consuming batches. Each stage has throughput and a queue capacity; memory pressure comes from mismatched rates rather than a single parameter. Tradeoffs: larger prefetch boosts utilization but raises pinned RAM; faster loading helps only if transfer and compute keep up; larger VRAM backlog smooths bursts but increases VRAM residency; bigger batch size raises memory footprint. Practical guidance: balance stages for stable throughput; adjust depth, loader rate, and batch size; VRAM also includes weights and optimizer state.

Google disclosed YouTube generated more than $60bn in 2025 revenue, combining ads and paid subscriptions, surpassing Netflix. Growth came from subscriptions (YouTube Premium and other tiers) and stronger retention in its ecosystem. Q4 ad revenue was $11.38bn, below expectations, while Shorts averaged more than 200 billion daily views. In the UK, YouTube was the second-most watched service (94% of adults; about 51 minutes daily). Analysts note most content is user-generated; Google plans to boost AI investment and expand subscriptions, with Oscars to be hosted on YouTube from 2029.

Cheap design argues design is the expensive bottleneck in both physical and software realms. 3D printing reduces fabrication costs but sacrifices strength, so standard parts endure; in software, libraries and frameworks solve design costs yet introduce dependency drift and maintenance burden. LLM-assisted coding lowers the cost of one-off tooling (jigs, converters) and enables generated code to be viable. The shift is from glue-heavy builds to exact-fit, generated modules; hard problems still deserve libraries, while some custom code ends up shorter. Design becomes cheaper, but not free.

After years of running a public git server (since 2011) and even a CVS before, the author abandons self-hosted git due to AI scrapers hammering the cgit frontend. Repositories are now primarily hosted on GitLab/GitHub, with dangling links updated to the forges. The only remaining self-hosted service is the webserver for the blog, which is static since 2018 (Jekyll). A prior AI-triggered outage overflowed logs, prompting a fixed config. The move marks the end of an era, with a nod to Security Nightmares.

Jeff Geerling and his dad toured a modern SMPTE 2110 broadcast truck during St. Louis Blues games to understand live digital timing. They saw two Evertz grandmasters for PTP-based synchronization of video, audio, and metadata, with a Tektronix PRISM tool for debugging and manual clock setting via an Atomic Clock app when GPS isn’t reliable. The truck uses hybrid fiber/copper cabling, a large patch bay, and a Calrec Artemis console, emphasizing human teamwork as much as technology. The video captures the atmosphere better than words.

Small boards are 24V/6V demonstration units showing pinball devices (solenoids, relays, pop bumpers, flippers and zipper flippers, steppers, ball-count, credit, score reels, projection and spin units). Each board links to neighbors to form a powered display string; each includes an instruction card and related videos. The page explains device basics, operation, patents, and provides deeper sections and resources for pinball mechanisms and repair.

FOSDEM 2026 presents Willow - Protocols for an uncertain future, a talk in the Local-First, sync engines, CRDTs track. The illustrated, musical presentation examines how to design peer-to-peer protocols that are harder to weaponise, drawing on past centralised and peer-to-peer abuses. It introduces Willow, a family of open-source, publicly funded protocols, by worm-blossom collective with speaker Sammy Gwilym. Details: Sunday, room K.3.201, 15:55–16:20 (UTC+1). Resources include Willow homepage, source code, and video recordings with subtitles.
