How far can you push the range of Wi-Fi connectivity in an ideal environment?

Phidgets tested 2.4 GHz Wi‑Fi range under licence limits. Using a 0.1 W transmitter and up to 16 dBi antennas with a Phidget SBC4 and 802.11n adapters, they measured ~430 m with stock 2 dBi antennas and ~1,400 m with higher-gain antennas (12 dBi omni, 14 dBi Yagi) in line‑of‑sight. Conclusion: 1.4 km is feasible under ideal conditions with proper gear; performance drops off with misalignment or obstacles.

How to Exist

An experiment in existing: sit for three minutes with two rules—don’t move and be content with the present. The piece argues the human mind is allergic to the present, always seeking escape through things, scrolling, or rumination, and cites studies showing people dislike idle thinking. It prescribes a practical path: practice existing in short, fearless bouts—attend to the whole experience with breath as a timer. Start with a half-breath, build to longer cycles, aim for five minutes. Benefits include greater ease, less need to distract, and calmer interaction with everyday life.

A past and future of trade secrets

Klára Kofen's “The Detritus of Our Days” uses speculative futures and a meta-historical lens to examine trade secret law as a changing architecture of knowledge protection. Drawing on Webster’s Timeline History: Trade Secret, 1624–2007, and vignettes from 2029–2244, she traces the shift from guild secrecy to modern corporate and AI-era protections, framing secrets as epistemic boundary objects that mediate what counts as knowable. The essay argues history is assembled from gray literature and detritus, and calls for open, public knowledge even as it scrutinizes the fragility and moral issues of information enclosure in a fragmented world.

Hope and Defeat: John Berger

Owen Hatherley surveys the Berger centenary wave, focusing on Four Horizons, John Christie’s self-published account of Berger and Le Corbusier’s Chapelle Notre-Dame du Haut, made with two Benedictine nuns. The volume assembles photographs, Berger’s unfinished dialogue, an obituary of Le Corbusier, and responses by Teju Cole and Paul Clarke. Hatherley frames Berger’s late work as a tension between blunt humanity and gnomic piety, tying his concerns—poverty, art, capitalism, and Palestine—with his rural later years. Four Horizons portrays hope amid defeat, Berger’s idea that modernism’s promises linger, like hope kept inside Pandora’s box.

The First Transatlantic Telegraph Cable Was a Bold, Beautiful Failure

Allison Marsh's Past Forward column recounts the 1858 attempt by Cyrus Field’s Atlantic Telegraph Company to lay a transatlantic cable. Despite groundbreaking design (Bright and Thomson) and government subsidies, the cable repeatedly failed—ships broke, paying-out gear jammed, and a mid-Atlantic splice was abandoned after the line degraded. About 732 messages were sent before the cable failed; blame fell on the chief engineer, Whitehouse, though later analysis blamed manufacturing flaws. Field persisted, and a permanent transatlantic cable finally connected Newfoundland to Ireland in 1866, proving the era’s dream of instant cross-Atlantic communication.

Everything is cloud-based, centrally managed, and portable via tilde-state.yaml; docs llms.txt guide setup.

Show HN: I worked on a new browser for 2 years, today it passed Acid 3

cwbrowser is a desktop browser with a from-scratch rendering engine written in Zig, using a hand-built HTML parser, DOM, CSS cascade, layout, and paint pipeline, plus Google's V8 for JavaScript. After two years of solo work, it reportedly runs ~2× faster than Chrome on the same hardware and achieves a perfect Acid3 score (100/100). It does not reuse Chromium/WebKit/Gecko. A macOS Apple Silicon preview is coming; sign up via [email protected]. See acid3.acidtests.org for the 100/100 result.

You have been mislead about lightbulbs

Debunks the myth that Phoebus cartel fixed incandescent bulbs at 1,000 hours to boost sales. The standard aimed to avoid a race to the bottom, but longer lifespans trade off with color, brightness, and efficiency: hotter filaments glow whiter but wear out faster; early bulbs used carbon or tantalum with limited efficiency. Modern lamps improved with fluorescent and LED tech. Packaging confuses brightness with power, and a 60 W/4 W mismatch can mislead buyers. The famous 120-year lamp is likely an anomaly. Dubai LED filaments achieve ~200 lm/W but costlier.

Authorize, don't authenticate

Authorize, don’t authenticate promotes user control over data by letting apps access a personal database rather than requiring user login. Using ayb, apps obtain OAuth2 tokens to query a database you own, with creation flows as simple as making a document, automatic backups, and the ability to revoke access. ayb is open source, optionally self-hosted, and stores data in standard formats like SQLite/DuckDB. While this can reduce centralization, collaboration complicates ownership. The author envisions broader adoption, export/import, and more login screens replaced by database authorization.

Twenty-five years ago it was cryptography, today it's model weights

Anuradha Weeraman draws a parallel between 1990s crypto export controls and today’s AI safety/export restrictions. She recalls donating to OpenBSD and receiving Blowfish code on a t-shirt, a symbol of protest for universal strong cryptography. The same logic resurfaces as US policy restricts foreign nationals from touching models; real incidents show attackers bypassing safety, while defenders are constrained by rules. The OpenBSD approach—distributed development across Canada, Sweden, and Germany—showed that 'because we can' exists. Now weights from Mistral, DeepSeek, Moonshot and Zhipu can be downloaded worldwide, challenging sovereignty. Frontier AI will reach broad access, but only with deliberate action.

Let's make the worst Htmx

Explains building a lightweight HTMX clone (x.js) to demonstrate how HTMX works: declarative attributes trigger AJAX, swap responses into targets without writing JavaScript. The author implements a generic fetch-based engine: scan for x-*, decide method/trigger/target/swap, send requests, replace target content, and re-scan after swaps. Adds optimizations with MutationObserver, robust target resolution, and a flexible swap system (outerHTML, beforebegin, innerHTML, delete, etc.). Extends with custom events (x:beforeSend, x:afterSwap) and server headers (HX-Trigger, HX-Redirect). Proposes a plugin-friendly API (SSS: scan, send, swap) and compares to HTMX; code at github.com/zserge/x.

A simple clustering algorithm for lists

Cassidy Williams describes a greedy, human-friendly clustering method for lists: repeatedly take the rightmost value, find the next same-valued item from the end, and reverse the sublist between them to move that cluster toward the back. Repeating on the next incomplete cluster yields a fully clustered list (e.g., b, g, o, r). Inspired by sorting puzzles and Magna-Tiles, the approach is easier for humans than computers and runs in O(n^2). She provides a JavaScript implementation and notes it’s for exploration rather than efficiency, likening it to pancake sort.

Using the railway network as a flatbed scanner [video]

Philomena Gray's emf2026 talk, “Using the railway network as a flatbed scanner,” explains capturing ultra-wide images from a moving train with an industrial linear camera, then stitching thousands of lines per second into a coherent panorama. It covers pacing the speed measurement, acquiring lines quickly enough, and processing/displaying the resulting images. The talk is on Stage A at emf2026 (Day 2, Chaos Computer Club), with downloadable video and audio in multiple formats under CC BY-SA 4.0.

Severance

A satirical Substack post shows a company layoff call where Mark announces a 7% workforce cut, including everyone on the video call, citing a poor macroeconomic outlook and project sunset. Christine explains the transition and outlines the severance package: up to two weeks’ tokens to aid the job search, plus ThriveFlow-provided grief-counseling prompts as an optional resource.

How to Survive an Infestation of Toxic Caterpillars

In Berlin’s 2026 heat wave, oak processionary caterpillars outbreak—hairs that cause excruciating rashes and can become airborne—remade summer nuisance into a public-health threat. The insects, spreading across Europe as climates warm, trigger alarms from city workers in protective gear vacuuming nests to discussions of pesticides; insecticides are largely ineffective and nematodes offer only partial relief. The piece links the pest to climate change, notes its expanding range in Britain, Denmark, the Netherlands, and beyond, and ends with reflections on humanity’s kinship and control over nature.
