<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
A version of DOOM was developed that uses CSS for all visual rendering, including 3D projection and lighting, while JavaScript handles the game logic. It shows how modern CSS features like `transform` and `@property` can manage complex geometry and animations without relying on traditional rendering engines.

The author decrypted Cloudflare Turnstile programs used by ChatGPT, revealing a sophisticated bot detection mechanism that analyzes the internal state of the React application to make sure it's a genuine environment. This system identifies bots by verifying application-level state and behavioral biometrics, although its security relies more on complex obfuscation than true encryption.

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
An experienced engineer argues against using AI coding agents for production, citing skill atrophy, unsustainable costs, security risks, and legal uncertainties regarding copyright. While useful for research or personal projects, these flaws make them unsuitable for professional software development and core business code.

The author reflects on 40 months of AI, acknowledging the utility of interfaces like Claude Code while questioning AI's overall impact on coding productivity and creative quality. Despite recognizing its potential for expert-level tasks, he is still skeptical of its ability to replicate personal style or handle complex software development without human intervention.

Pretext is a pure JavaScript/TypeScript library for fast and accurate multiline text measurement and layout. It circumvents costly DOM reflows by implementing its own text measurement logic using the browser's font engine. The library has two primary use cases: calculating a paragraph's height without DOM interaction for purposes like virtualization, and providing tools to manually lay out text lines for rendering to Canvas, SVG, or server-side.

AI agents are already causing data loss, from wiped home directories to deleted files, when granted ordinary machine access. jai provides an effortless, one-command solution for containing these agents on Linux, bridging the gap between full system access and complex virtualization. It works by giving your working directory full access while protecting your home directory with a copy-on-write overlay or complete isolation.

<strong>The Cognitive Dark Forest (6 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
The early internet was an open "bright meadow" where sharing ideas and code led to innovation and success. However, corporate consolidation and the advent of AI have transformed it into a "cognitive dark forest." In this new environment, AI platforms can cheaply absorb emerging human innovations by analyzing user interactions and data, effectively owning the compute, models, and developer data.

<strong>AI Agents Could Make Free Software Matter Again (25 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
AI coding agents are going to make "free software,” defined by users' freedoms to run, study, modify, and share, more relevant than ever. Historically, the rise of SaaS reduced free software's importance as software running on remote servers made source code access impractical for most users. However, agents can now act as intermediaries, allowing even non-technical users to customize software directly if its source code is accessible.
