Security and Correctness in Wasmtime

The essence of software engineering is making trade-offs, and sometimesengineers even trade away security for other priorities. When it comes torunning untrusted code from unknown sources, however, exceptionally strongsecurity is simply ...

[Перевод] Запускаем WebAssembly модули с Python хоста

WebAssembly - молодая, но довольно перспективная технология. WASM позволяет упаковать программу в бинарный формат, который можно запускать на любой системе, в изолированной среде. В статье посмотрим как WASM-модули взаимодействуют с Python хостом. (Спойлер - не все так просто как хотелось, поддержка WASM в Python экосистеме пока слабая)
