Datasette Apps: Host Custom HTML Applications Inside Datasette
Simon Willison's Weblog39 days agoNew ToolSimon Willison has launched datasette-apps, a new Datasette plugin that embeds sandboxed HTML+JavaScript applications directly inside a Datasette instance, giving each app live read-only SQL access to the underlying SQLite data. Apps run inside tightly restricted iframes using a combination of the sandbox attribute and injected Content Security Policy headers, preventing untrusted code from accessing cookies, localStorage, or external hosts. The concept originated from Willison's effort to replicate a Claude Artifacts-style experience inside Datasette Agent, before being promoted to a standalone top-level plugin.
10,000 GitHub Repositories Found Distributing Trojan Malware
Hacker News (AI keywords)40 days agoIncidentA security researcher published findings identifying approximately 10,000 GitHub repositories that distribute Trojan malware. The scale of the campaign suggests an organized, systematic effort to abuse GitHub's trusted platform for malware distribution. Developers and open-source consumers who clone or run code from unvetted repositories are at direct risk.

Leanstral: Open-Source Foundation for Trustworthy Vibe-Coding
Mistral AI News40 days agoPaperMistral AI has introduced Leanstral, an open-source research project aimed at bringing formal trustworthiness to vibe-coding — the increasingly popular practice of generating software through natural-language AI prompts with minimal manual oversight. The initiative frames itself as a foundational layer, suggesting it is designed to underpin other tools or workflows rather than serve as a standalone end-user product. By releasing it as open-source, Mistral directly addresses one of vibe-coding's sharpest criticisms: that speed and accessibility come at the cost of correctness and verifiability.

Datasette 1.0a34
Simon Willison's Weblog41 days agoReleaseDatasette 1.0a34 ships native CRUD operations in the browser interface, letting users insert, edit, and delete rows directly from table and row pages. The feature was prompted by Datasette Agent, which recently gained SQL write support, creating an awkward asymmetry where the AI chat interface could modify data but the standard UI could not. The release moves Datasette meaningfully closer to a lightweight data-management tool rather than a read-only data publishing layer.
Capacitor Alarm Clock: Open-Source Plugin for Mobile Alarm Scheduling
Hacker News (AI keywords)44 days agoNew ToolCapacitor Alarm Clock is a community-published GitHub project offering a native alarm scheduling plugin for Ionic Capacitor apps.

Quoting Jeremy Howard on Anthropic's Recursive AI Self-Improvement Contradiction
Simon Willison's Weblog47 days agoEthicsJeremy Howard proposes that labs claiming to slow recursive AI self-improvement should ban themselves from using their top model for frontier research while letting others access it. He argues Anthropic does the opposite — using its best model internally while reportedly blocking others from doing the same — accelerating the frontier and worsening power imbalance. Howard personally favors democratization over slowdown, but his point is about consistency: if you preach restraint, constrain yourself first.
Apache Burr: Open-Source State Machine Framework for Building Reliable AI Agents
Hacker News (AI keywords)47 days agoNew ToolApache Burr provides a state-machine-based architecture for building reliable AI agents, making complex multi-step LLM workflows predictable and testable.

Building from Zero After Addiction, Prison, and a Felony
Hacker News (AI keywords)50 days agoCommentaryGavin Ray recounts entering juvenile prison at 14, becoming a felon at 19, and losing stability to addiction. The essay follows his path back through software work, open source, Hasura, and people willing to judge him by future contribution rather than only past record. AI is not the focus; Claude Code is only mentioned as the tool used to generate the OpenGraph SVG image.
Show HN: Paseo - Beautiful open-source coding agent interface
Hacker News (AI keywords)55 days agoNew ToolPaseo provides one interface for tools such as Claude Code, Codex, Copilot, OpenCode, and Pi. It runs agents through a local daemon on the user's own machine and supports desktop, mobile, web, and CLI clients.

I Am Retiring from Tech to Live Offline
Simon Willison's Weblog58 days agoEthicsSimon Willison highlights Chad Whitacre’s decision to leave tech and Open Source, framed not as a forum threat but as concrete action. Whitacre describes wanting to become “AI Amish” or “Internet Amish,” moving toward an offline, analog life closer to 1980 than 1780. A previous post about using Claude Code with Opus 4.5 shows how agentic AI felt intoxicating and unsettling enough to push him away from technological accelerationism.
Armin Ronacher on the Frustration of AI-Generated "Slop" GitHub Issues★ 72
Simon Willison's Weblog64 days agoCommentaryFlask creator Armin Ronacher highlights a frustrating trend where users submit GitHub issues reworded by AI. These reports often present highly confident but inaccurate root-cause guesswork, fake minimal reproductions, and irrelevant error logs. Ronacher advocates for returning to simple, human-observed facts: what command was run, what was expected, what actually happened, and the exact logs.
Building Pi with Pi
Hacker News (AI keywords)64 days agoOpinionIn this personal blog post, Armin Ronacher — creator of Flask and prominent Python/OSS contributor — explores the concept of building an open-source AI tool or agent named Pi by leveraging Pi itself. The 'pi-oss' URL slug suggests the piece centers on open-source themes. The self-referential title implies a bootstrapping or dogfooding narrative common in developer tooling essays.
