Writing a better reality: The case for optimistic sci-fi

An advocate for optimistic science fiction, the article argues fiction can imagine better futures without being utopian. Sci-fi often critiques real-world contexts through speculative worlds, exploring themes from government power to environmental anxiety. It cautions that technology sometimes creates new problems, so the aim should be a technologically solutionist approach rather than outright optimism. Examples like The Martian's problem-solving ethos and Star Trek's harmonious technocultural future illustrate how tech can enable progress without perfection. Ursula Le Guin’s call for hope anchors the case: to shape a better future, we must first envision it.

Show HN: Is It Greg?

Is It Greg? is a tiny Chrome extension for Hacker News that highlights submissions linking to greg.technology (and subdomains) as well as stories and comments posted by Greg (gregsadetsky). It shows an orange Greg badge and Greg dancing on the page, with a tally of sightings; clicking the badge jumps to the next sighting. It requires no build step or dependencies beyond running on news.ycombinator.com. Install via chrome://extensions > Load unpacked (point to this repo). MIT license.

AI is not a normal technology

The piece argues that AI is not a normal technology because it is fully general and can, in theory, do everything humans can. This makes the job question tautological: if AI outperforms humans, it will supplant jobs, and new roles can be AI-driven too. Authentic human-made work remains valuable only because authenticity is rare; as AI makes writing and other tasks ubiquitous and cheap, value shifts toward seniority and taste, widening inequality. Even math and science worry about misaligned goals. Policy may slow nothing; at bottom, only being human stays uniquely valuable.

Necker, 1832: "An optical phænomenon on viewing a figure of a geometrical solid"

Necker, L. A.'s 1832 paper reports remarkable optical phenomena seen in Switzerland and a phenomenon occurring when viewing a figure of a crystal or geometrical solid. The Zenodo record (CC0, DOI 10.1080/14786443208647909) provides open access to version v1, with ~3,000 views and ~1,750 downloads.

Open-Source AI and Open Models Reading List

An updated, curated reading list of open models and open-source AI, meant as a comprehensive overview for policy and public writing. It groups materials into foundations (what open models are, why release them, economics, safety), US–China competition and policy implications, and technical/risk discussions (distillation, data, cyber risks, guardrails). Highlights include influential essays, industry notes, and regional analyses (notably China), plus adoption and performance gaps between open and closed models. The author invites comments and updates.

The case against JPEG XL

The author argues JPEG XL, while technically impressive and useful outside the Web, is not a good fit for browsers. On the Web it offers limited lossy gains (modest savings over WebP) at the cost of slower decode, no reliable progressive decoding, and missing web-friendly features (directional prediction, deblocking). Its XYB color space and patch-based tools complicate web encoding, especially for non-photographic content. Modern encoders (AVIF/WebP) outperform it on perceptual metrics, and libjxl lags. The Web should favor narrowly scoped, fast codecs; JPEG XL’s real value may be outside browsers.

Mullenweg has returned as CEO after attempted board ouster

Automattic confirms Matt Mullenweg has returned as CEO and chairman after a board vote earlier in the week placed him on paid leave and named CFO Mark Davies interim CEO. Mullenweg allegedly wrested control by removing admins from Slack and tweeting "I'm a pirate" after vowing to fight the move. He offered no formal comment on his return; TechCrunch notes several upheavals, including unconfirmed reports that Toni Schneider was stepping down and ongoing board changes, with the board publicly backing Mullenweg.

Why is privacy so hard?

ACM.org access is blocked by Cloudflare’s security check, requiring cookies. The page explains the block was triggered by actions that could resemble an attack (e.g., certain words, SQL commands, or malformed data). To resolve, email the site owner with what you were doing and include the Cloudflare Ray ID shown (Ray ID: a3ab03ae59ddfb3c) and your IP (192.155.84.206).

The GDR and Vietnam: From Fake Coffee to Coffee Empire

Katja Hoyer recounts how East Germany helped Vietnam build a coffee industry in the 1980s to offset shortages, sending machinery, irrigation, roads, and a hydropower plant in Dak Lak; in return the GDR would receive half of Vietnam’s coffee for 20 years. The project helped Vietnam become a top coffee producer, though the first harvest came in 1990 after the GDR collapsed. It highlights GDR scientific rigor, women’s equal roles on the plantations, spice and tea collaborations, and argues for a nuanced view of GDR history beyond repression.

Registration without a phone number on Signal will use zero-knowledge proofs

Signal Community discusses enabling registration without a phone number, using zero-knowledge proofs (ZKPs) to verify identity and protect privacy for donations, groups, and usernames without data linkage. Posts show Android updates adding numberless registration/login, password manager support, zkgroup credentials, UI tweaks, and backup improvements. Debates address whether unlinking a phone number from an existing account is possible or safe, risks of spam, and cooldowns. Overall, work aims to make numberless accounts practical while addressing privacy and security concerns.

The Contagion of Fear

An author recounts a campus prank that sparked mass panic to illustrate how fear about AI and human extinction spreads when experts overstate risks. He argues that claims of imminent extinction—often unsupported by evidence—fuel contagion, while AI’s real power remains bounded by physical systems under human control. The burden to prove extraordinary claims lies with the proponents; public trust must not be abused. For now, there is nothing to fear about extinction.

A computational constitution to stop LLM agents from bricking servers

Misqe/zero-trust-llm proposes a zero-trust framework to govern LLM-driven agents in production. It argues current LLMs are over-tuned and prone to unsafe actions; demos mislead and natural-language governance fails over context. The solution strips agency and enforces an epistemic state machine via AGENTS.md, centered on a master loop: [HYPOTHESIS] [IDENTIFY EVIDENCE] [GROUND VERIFICATION] [EXECUTE] [HARD YIELD TO OPERATOR], with a runtime enforcer that cuts the API stream and feeds results back. The repo also includes MANIFESTO.md, examples, and architecture notes.

Bad Code Is Kudzu

Vicki Boykis compares bad code to kudzu: once a feature is added, it grows hard to remove as others build on it. The post argues for aggressive pruning and planning removals from the start, since deleting code is thankless yet necessary to prevent a bloated codebase. An example shows a blog hashtag-bubbles feature that users rarely used and was ultimately pruned along with its commit history.

Flawed Routers Flood University of Wisconsin Internet Time Server (2003)

UW-Madison faced a massive SNTP flood in May 2003 targeting its public NTP server from hundreds of thousands of hosts worldwide. The flood stemmed from a design flaw in Netgear “Platinum” consumer routers (RP614, MR814, DG814, HR314) that shipped with an embedded SNTP client using a hard-coded NTP server IP (128.105.39.11) and a fixed source port (23457). Netgear cooperated and firmware fixes were developed. Proposed responses included deploying a secure anycast NTP service or suppressing requests via BGP, both with implementation risks. The incident spurred discussions on SNTP/NTP standards and best practices.
