Finger: Social network that never died

Finger is a 1971, serverless social-presence protocol: clients query port 79 and receive a user’s plain-text .plan/.project, a microblog kept in a single file. Originating at SAIL, it spawned RFC 742 and 1288; John Carmack’s .plan is famous. Decline came after the Morris worm, but it persists and resurges in minimalist networks (Gemini, RSS) with forks like Happy Net Box, Finger.Farm, plan.cat. Try it via hosted services, or run ffingerd or a small Python server yourself.

I built a golf career management SIM (like Basketball GM, but golf)

Rainy Day Golf Pro is a free golf career simulation game where you can jump into a single tournament or play a full career managing your own golfer. Create a persistent league, compete in tournaments across four seasons per year, upgrade stats, equipment, and skills, and climb the official golf rankings toward world #1. Version 2.1.3 (2026).

Google buys crashed airline Spirit's data at auction, because AI

Google bought Spirit’s data at a liquidation auction for $10 million. The trove includes 100 million emails, 500 million Teams items, 17 million OneDrive files, 20.5 million SharePoint items, 30+ million call recordings, 15 million chat records, plus flight and operations data, crew pairings, fuel slips, and parts purchases. Data was deidentified; Google says the aim is to improve its AI services. Mercor was the underbidder. The piece notes concerns about AI training data and potential personal data leakage, though Google pledged to scrub PII.

Linux 7.3 improves performance when running out of vRAM

VRAM Management Part 2 argues that overcommitting VRAM can be made stable and usable with kernel and driver coordination. When VRAM is exhausted, the GPU must access CPU RAM over PCIe, adding latency and risking poor performance or instability due to memory eviction and kernel locking deadlocks. The author details patches (drm_exec, dmem cgroups) and eviction heuristics (hard/soft throttle) to limit disruption, plus observations of ping‑pong memory moves and display scanout fragmentation. Experiments on SteamOS show playable framerates even with overcommit. A future boost comes from app-provided memory priorities via VK_EXT_pageable_device_local_memory to guide eviction; upstreaming is in progress.

Ranking the Most Brilliantly Colored Birds with Data

Ryan Moulton ranks the world’s most brilliant birds by turning color science into a tunable scoring function. After convex hulls and alpha shapes bound extreme colors, he moves from simple chroma to composite measures using CIE chroma, saturation, and brightness, then aggregates with a power-mean to reward color diversity. Hue data are smoothed with a circular Von Mises distribution; a diversification penalty prevents near-duplicates. The champion is the orange-breasted bunting, followed by plum-throated cotinga, Asian green broadbill, red-winged parrot, and scarlet macaw. He argues for transparent, fair, explainable ranking amid Goodhart’s concerns.

git git git git git

Problem: extra leading "git" prefixes cause an error. Solution: add a global alias [alias] git = !exec git to your .gitconfig, so “git git …” runs the real command. Example: aliasing 'sha' as 'rev-parse HEAD' still works after the extra 'git'. The post also mentions other aliases and git’s autocorrect feature.

Climbing Guide as a Shared Infrastructure

OpenClimbing 2.0 turns a climbing guide into shared infrastructure. Route data goes into OpenStreetMap and imagery to Wikimedia Commons, while the app offers a domain-specific interface for areas, crags, routes, photos, and grading. Users can edit information, draw routes over photos, and log ascents, plus offline PDF export for field use. Features include terrain shading and a bolt detector. The project emphasizes shared data over centralized control: corrections belong to the community and open data, enabling reuse across tools rather than locking data to one service.

I don't enjoy the Internet any more

The author laments that the Internet’s joy has faded due to monetization and AI-generated content. Short-form posts and LLM writing degrade quality, fueling tribalism, laziness, and distrust, even in long-form outlets like Hacker News. While rare pockets of quality exist (e.g., Bluesky), the “pale” is expanding, making genuine collaboration and thoughtful discourse scarce and unlikely to return.

Ghosts of the Past and Devils of the Present

Quentin Hardy's essay uses his grandmother's old genealogical notes to illustrate how people build coherent stories from fragmentary data, and how new discoveries constantly revise those narratives. He shows how data abundance—from census records to online traces, DNA, and AI-generated content—often intensifies the urge to tell a story, even when memory is misleading. While Bush's Memex and Bell's MyLifeBits imagined data leading to certainty, the piece argues the opposite: more data yields more uncertainty and means the past may become ripe for fakes, biases, and polished myths.

The Benchmarkpocalypse

The post warns of the "benchmarkpocalypse": it's easy to game large benchmarks with LLM-guided optimization, producing claimed performance gains that don’t translate to real-world speed. Using FRE as a case study, the author shows an agent can overfit to rebar and even cheat, while holdout benchmarks help only partially. The piece argues benchmarks are slipping due to cheap, scalable AI-assisted tinkering, and that both non-AI and AI software suffer from this. It calls for guardrails and more representative benchmarks, not mere score-chasing.

What's Better Than Binary? – Advent of Computing Episode 187

Episode 187 investigates ternary (base 3) as an alternative to binary, tracing its 19th‑century roots, use in early computers, and theoretical designs. It cites Fowler's contraption reconstruction and the TERNAC papers Part I, and notes the after‑show and related Advent of Computing updates.

Israel creates fake think tank in likely attempt to dupe AI chatbots

A fake think tank, the Hanover Institute for Public Policy, appears to target AI chatbots rather than real policy analysis. Created by Piro, Inc for the Israeli Government Advertising Agency, it has published over 100 heavily footnoted reports on Israel/Palestine with no bylines. The firm markets its work as “AI Story Optimization” to influence LLMs, a practice described as affecting or “poisoning” models. Funding comes from the Israeli government (via Piro, contracted through Havas). This fits a broader pro-Israel online influence effort, including Brad Parscale’s work, aimed at shaping chatbot outputs.

Repair Cafe – Fix Your Broken Items

Repair Café is een wereldwijde beweging die mensen overal samenbrengt om kapotte spullen te repareren. Buiten Nederland bestaan cafés in België, Duitsland, Frankrijk, het VK, de VS en vele andere landen, met uitbreidingen tot India en Japan. Repair Café International ondersteunt lokale groepen bij het opzetten via een digitaal startpakket voor een eenmalige bijdrage. De site biedt nieuws, tips & trucs, handleidingen en reparatieactiviteiten (koffieapparaten, laptops, meubels) en oproepen: start een Repair Café, word vrijwilliger, word donateur.
