I’m sure many of you are familiar, but there’s a treacherous gap between finding (or building) a model that works in PyTorch, and getting that deployed into your application, especially in consumer-facing applications. I’ve been very interested in solving this problem with a great developer experience. Over time, I gradually realized that the highest-impact thing to have was a way to go from existing Python code to a self-contained native binary—in other words, a Python compiler. I was already pretty familiar with a successful attempt: when Apple introduced armv8 on the iPhone 5s, they…

QuickBEAM is a JavaScript runtime embedded inside the Erlang/OTP VM. If you’re building a full-stack app, JavaScript tends to leak in anyway — frontend, SSR, or third-party code. QuickBEAM runs that JavaScript inside OTP supervision trees. Each runtime is a process with a `Beam` global that can: - call Elixir code - send/receive messages - spawn and monitor processes - inspect runtime/system state It also provides browser-style APIs backed by OTP/native primitives (fetch, WebSocket, Worker, BroadcastChannel, localStorage, native DOM, etc.). This makes it usable for: - SSR…

I really couldn't find a simple wrapper to pycrypto that would encrypt data correctly in Python 3. So I tried to follow the instructions at http://www.daemonology.net/blog/2009-06-11-cryptographic-right-answers.html (written by HN's cperciva) and wrote https://github.com/andrewcooke/simple-crypt Is that OK? Given the problems Tarsnap had with CTR mode, was it wrong to follow those instructions anyway? Have I got the offset handling right? It seemed like it would be better to write this once, get it revised here, and then publish it (I'll make an egg for pypi once it seems OK) than quietly…
