--- title: Browser Workflows, Compiler Experiments, and Practical Tools date: 2026-10-20T18:00:00.000+02:00 week_number: 43 notes: "**TL;DR:** Declarative demos, visual data tools, compiler experiments, and smarter browser controls stood out, alongside useful ideas for security, rendering, and image-format trade-offs." links: - title: Deno is joining Cloudflare url: https://deno.com/blog/cloudflare comment: The whole Deno team is joining Cloudflare. Deno Deploy is set to shut down in six months; the open-source runtime gets a year of monthly fixes and security updates before the team ends its development. Those are distinct timelines, and the code remains open source. tag: news - title: TanStack Start 1.0 is stable url: https://tanstack.com/blog/tanstack-start-1-0 comment: TanStack Start has reached its stable 1.0 release. It's a full-stack web framework built around TanStack Router; a useful milestone for anyone who's been watching it mature from its release candidates. tag: news - title: Mozilla introduces Firefox Enterprise url: https://blog.mozilla.org/en/firefox/introducing-firefox-enterprise/ comment: Mozilla pairs Firefox's independent Gecko engine with a management console organizations can run on their own infrastructure, covering policy, data movement, and AI controls. This could give Mozilla a distinct enterprise business around browser choice. tag: news - title: OpenCode 2.0 url: https://anoma.ly/notes/opencode-2-0/ comment: "OpenCode 2.0 opts MCP servers into code mode by default: agents can compose several tool calls in a script instead of making each round trip separately. A neat way to reduce both tool overhead and context bloat." tag: news - title: Testing an iframe's postMessage handler url: https://blog.master.dev/testing-an-iframes-postmessage-handler/ comment: The tests cover wrong origins, messages from an unexpected window, malformed values, and negative or wildly large heights. A useful security-minded checklist for code that accepts messages from embedded frames. tag: article - title: JPEG XL vs AVIF for web use-cases url: https://jakearchibald.com/2026/jpeg-xl-vs-avif/#conclusions comment: "A careful codec comparison: AVIF usually wins for lossy web images, especially screenshots and illustrations, while JPEG XL shines for lossless use and some outliers. The practical advice is to test your own images rather than assume one format always wins." tag: article - title: Yet another way to invoke functions without parentheses url: https://blog.ikaes.de/yet-another-way-to-invoke-functions-without-parentheses/ comment: A JavaScript security puzzle that chains Error.prepareStackTrace, prototype changes, and value coercion to generate and invoke code without parentheses. A good reminder that blocking one syntax doesn't make a safe execution boundary. tag: article - title: The art of dithering and retro shading for the web url: https://blog.maximeheckel.com/posts/the-art-of-dithering-and-retro-shading-web/ comment: A hands-on tour of retro shading effects with custom post-processing shaders in React Three Fiber. The interactive examples make dithering and pixel-style rendering feel approachable, not just like shader math. tag: article - title: The best way to use icons in web UIs url: https://lea.verou.me/blog/2026/icons/#demo comment: Lea Verou explores treating icons as CSS variables and design tokens, so stylesheets can choose or change them with state and media queries. That's a compelling alternative to scattering icon-specific classes through markup. tag: article - title: WebReel url: https://webreel.dev/quick-start comment: Write a JSON recipe for a website, viewport, and sequence of actions, then record it as a video. I can see this being handy for repeatable product walkthroughs and launch clips. tag: library&tools - title: Visual JSON url: https://visual-json.dev/ comment: A visual tree and form editor for nested JSON, with optional JSON Schema validation and hints. It also offers React and Vue components, plus a VS Code editor for JSON, JSONC, and YAML. tag: library&tools - title: Vercel's tsc-ts url: https://github.com/vercel-labs/tsc-ts comment: Vercel Labs ported TypeScript 7's Go compiler back to idiomatic TypeScript, then uses scriptc to build native binaries. A wonderfully strange compiler project, with broad compatibility checks against upstream. tag: library&tools - title: MobX React plugin url: https://github.com/mobxjs/mobx/pull/4735 comment: This draft pull request experiments with a MobX React plugin for the React Compiler, including examples of automatically observed components. It's an interesting integration idea, but still work in progress. tag: library&tools - title: Phloem url: https://phloem.stemdeck.app/?repo=stemdeckapp/stemdeck&t=315 comment: Phloem turns a Git repository's history into an animated, growing visualization. It makes the shape and timing of a project's evolution much easier to explore than reading a long commit log. tag: library&tools - title: Flipflop url: https://github.com/andunieee/flipflop comment: An open-source file-sharing tool for sending files between people. The "meatspace" framing makes me curious about the flow it uses to connect sender and recipient. tag: library&tools - title: spotatui url: https://github.com/LargeModGames/spotatui comment: A Rust terminal music player with Spotify streaming, local files, Subsonic, radio, Qobuz, and YouTube sources. That's an impressively broad music library to bring into a TUI. tag: library&tools - title: Crest url: https://crestbrowser.com/#tour comment: "An Arc-inspired browser with both Chromium and WebKit on Mac, so you can choose an engine per site. One useful caveat: cookies and site storage stay separate between the two engines." tag: library&tools - title: A TypeScript compiler port in Rust url: https://github.com/pingdotgg/ts-rust comment: "A different experiment: the author used LLMs to port the TypeScript compiler, checker, and language server to Rust, reporting over $420,000 in token value. An eye-catching way to probe what coding agents can do." tag: ai - title: Embedding Gemma Transcribe url: https://eg2.haku.sh/ comment: A small reader maps EmbeddingGemma 2's audio embeddings to words; the base model wasn't trained for speech recognition. The project reports one hour transcribed in 12.6 seconds on an 8 GB M3 MacBook Air, entirely on device. tag: ai --- I really like the Gemma as translation model and the typescript compiler which is compiled to the native code, totaly insane stuff!
