Speeding up Firefox Local AI Runtime (6 minute read)
Mozilla has accelerated Firefox's AI Runtime by replacing the WebAssembly-based "onnxruntime-web" with native C++ ONNX Runtime integrated directly into Firefox. This change delivers 2-10x faster inference performance for AI features like PDF alt-text generation (improving from 3.5 seconds to 350ms) and smart tab grouping, while removing WebAssembly warm-up overhead. |
Should you preload fonts for performance? (5 minute read)
Font preloading can improve website performance by eliminating double paints and layout shifts. However, it can also delay First Contentful Paint (FCP) since Chrome now blocks rendering until preloaded fonts arrive (with timeouts of 100-1,500ms). It's best to preload only essential above-the-fold fonts (maximum two), self-host them, and prioritize text fonts over icon fonts for better user experience. |
Partytown: Optimize Third Party Scripts with Web Workers (8 minute read)
Partytown is a library that optimizes website performance by automatically moving third-party scripts (like analytics, ads, and chat widgets) into web workers, allowing them to run in background threads instead of blocking the main thread responsible for rendering and user interactions. This approach can improve Core Web Vitals scores. One example showed a Next.js site's Lighthouse performance score jumping from 70 to 99 after implementing Partytown with Google Tag Manager. |

I don't want AI agents controlling my laptop (3 minute read)
Granting AI agents unfettered access to personal computers is not a great idea. There is a lack of granular control over permissions, making it difficult to protect sensitive information like passwords and API keys. However, there are two potential solutions: using cloud environments and virtual machines for isolated AI agent execution, and integrating AI controls properly within a web browser with enforced permission boundaries. |

Web3: Cryptography's New Frontier (6 minute read)

This shift has spurred research and funding in cryptography, but also raised concerns about security vulnerabilities due to the pressure to rapidly deploy new technologies. |
Default Methods in Go (8 minute read)
Go's structural typing system for interfaces creates problems when trying to add new methods without breaking existing code, as there is no way to provide default implementations. A workaround is to use Go's struct embedding feature combined with unexported interface methods to create "required embeds." This forces interface implementers to embed a default struct that provides default method implementations. |
