A developer has made Apple's abandoned Copland operating system runnable inside a web browser, using an enhanced version of the DingusPPC PowerMac emulator compiled to WebAssembly. The build shown is the final D11E4 version, and users can boot it, interact with its desktop, and launch included applications like GXSlidemaster and Eric's Solitaire directly from a webpage.
Cloudflare announced that Python Workers, the runtime it introduced two years ago to run Python code on its edge network, is now generally available. Developers can use existing Python code and popular frameworks like FastAPI, Django, and Flask, and connect them to Cloudflare services such as Workers AI, R2, D1, Hyperdrive, Durable Objects, Queues, and Workflows.
Flet has launched its 1.0 release, providing developers a complete framework to build, test, and ship Python applications across desktop, mobile, and web. The release includes over 150 UI controls, prebuilt Python packages for iOS and Android, browser support via Pyodide/WebAssembly, and tools like flet build for packaging apps for app stores.
Emscripten-forge has added OpenBLAS support to its NumPy package for WebAssembly, replacing the previous unoptimized fallback loops used for matrix operations in browser-based Python. Benchmarks show np.matmul on 1024x1024 matrices running roughly 30.92x faster for float32 and 14.90x faster for float64, with an upcoming OpenBLAS release and an optional Relaxed SIMD build promising further gains.
Apple's Swift language team has released Swift 6.4, which makes Swift Build the default engine in Swift Package Manager so projects compile identically on Linux, macOS, and Windows. The update also finalizes the Subprocess API at version 1.0 for cross-platform process management, expands C++ and Java interoperability, and speeds up WebAssembly execution via JavaScriptKit by up to 40 times.
A new project compiles the GNU Radio DSP engine and its Qt GUI sinks to WebAssembly, letting users build and run software-defined radio flowgraphs directly in a browser tab without installing Python or GNU Radio. It supports the same .grc flowgraph files as the desktop app, includes sample flowgraphs and IQ recordings, and can connect to RTL-SDR, PlutoSDR or HackRF hardware through WebUSB.
A developer re-ran libsodium crypto benchmarks across native x86-64 code and several WebAssembly runtimes (Wasmer, WAVM, WAMR, Wasmtime, wasm2c) using builds from mid-2024, mid-2025 and mid-2026 to see whether WASM performance is genuinely improving over time. The results show Wasmer leading, with WAVM, WAMR and Wasmtime close behind, and WAVM's optimizer notably strong at speeding up baseline portable WASM without extra instruction extensions.
A new open-source repository accompanies a technical blog post detailing how to build a rv32ima instruction-set emulator and run a minimal Linux system on it from the ground up. The project includes emulator code, a small set of emulated devices, machine configuration files, and WebAssembly-exposed functions, along with the Linux build configs needed to reproduce the setup.
Anubis, a proof-of-work challenge system designed to block aggressive AI scrapers, has finally shipped a WebAssembly-based version after roughly a year of development. The tool works similarly to Hashcash, forcing browsers to solve a computational puzzle before accessing a website, which is negligible for individual users but costly at scraper scale. Site administrators use it as a stopgap measure while better methods for detecting headless browsers are developed.
A new open-source project called ExactTeX extends LaTeX with optional annotations that let authors mark specific objects—like tables or figures—for verification before compiling to PDF. Unannotated content passes through unchanged as ordinary LaTeX, and a browser-based editor called Vitela runs the same compiler via WebAssembly for local checking without a server. The toolchain includes a command-line compiler, a language server for editor integration, and a test suite ensuring consistent behavior across all three interfaces.
