I built Ponytrail, a local audit trail for AI coding-agent edits
Every change, on the trail. Ponytrail is a small CLI and bundled agent skill for recording why files changed, showing those changes as a local history tree, and reverting files from a previous snapshot. It keeps the trail in .pony-trail/ inside your project. Treat that folder as local runtime state; it should stay out of […]
Claude Code’s ”extended thinking” is a summary- not authentic thinking
Claude Code records each session to disk. Those logs include “thinking blocks” — the model’s own reasoning as it works. I went to inspect that reasoning this weekend and found a signature (600 characters long) and no text. So I read the docs: https://platform.claude.com/docs/en/build-with-claude/extended-thinking Some details worth being aware of: Claude encrypts its reasoning into […]
Moebius: 0.2B image inpainting model with 10B-level performance
While 10B-level industrial foundation models have pushed the boundaries of image inpainting, their prohibitive computational costs severely hinder practical deployment. Constructing a highly optimized task-specific specialist offers a promising solution; however, extreme structural compression inevitably triggers a severe representation bottleneck. To conquer this, we propose Moebius, a highly efficient lightweight inpainting framework. We systematically reconstruct […]
Never Give Them Your Face
They want your face. It will be called safety. Verification. Age assurance. A small step to protect children. But strip the language away and the demand is plain: before you may speak, post, or read, you must first prove who you are. And the only way they’ve figured out how to do it is with […]

Pledging Another $400k to the Zig Software Foundation
My family is pledging another $400,0001 to the Zig Software Foundation (ZSF). This brings our total pledged support for ZSF to $700,000, after our initial donation in 2024. Zig continues to earn my respect as a technical project and as a community. The 2026 devlog shows steady progress on the hard problems of building an […]
Die analysis of the 8087 math coprocessor’s fast bit shifter
Floating-point numbers are very useful for scientific programming, but early microprocessors only supported integers directly.1 Although floating-point was common in mainframes back in the 1950s and 1960s, it wasn’t until 1980 that Intel introduced the 8087 floating-point coprocessor for microcomputers.2 Adding this chip to a microcomputer such as the IBM PC made floating-point operations up […]
window.showDirectoryPicker opens up a whole new world
Chrome introduced a new API, window.showDirectoryPicker() that allows the user to grant access to a directory on their computer and allow a website to read/write everything inside. Examples that have been thrown around are a local-first notes app, where you can grant it access to a folder full of Markdown notes, and you own the […]
Codex logging bug may write TBs to local SSDs
Issue Codex is continuously writing a large amount of data to the local SQLite feedback log database: ~/.codex/logs_2.sqlite ~/.codex/logs_2.sqlite-wal ~/.codex/logs_2.sqlite-shm On my machine, after about 21 days of uptime, the main SSD has written about 37 TB. Process/file-level checks show Codex SQLite logs are the main continuous writer. That extrapolates to roughly 640 TB/year. On […]
Investors get real-time view of UK bond market activity for the first time
Until now, data on bond trades was scattered across multiple sources, making it difficult to get a clear and complete picture of market activity. The new service brings it all together in one place. The launch builds on changes to the UK’s bond market transparency rules that came into force in December 2025. Those changes […]
