This bit-for-bit reproducible image is distributed under a new “repro” tag.The reason for this is due to one noticeable caveat: to ensure reproducibility, the pacman keys have to be stripped from the image, meaning that pacman is not usable out of the box in this image. While waiting to…

AI tools must not be used to generate, extract, or summarize material that is then attributed to a named source, whether as a direct quote, a paraphrase, or a characterization of someone’s views. We don’t publish claims based solely on AI-generated summaries, and reporters may not represent any material as “reviewed” unless they…

As is the nature of writing for a larger audience, it is a formal, safe announcement. As it should be. Writing must necessarily become impersonal at scale. But I would like to write something personal about why I am doing this. What is the goal of building exe.dev? I am already the co-founder of one startup that is doing very well, selling a product I love as much as when I first helped design and build it. What could…

🚀 Check out this trending post from Hacker News đź“– đź“‚ **Category**: đź“Ś **What You’ll Learn**: This is a demo of a toy language with dynamic typing, inline values, stack allocation, interior pointers, single ownership, and a limited form of borrowing - less expressive than rust, but much more expressive than second-class references (eg we can express external iterators). Since there is no static typing the borrows must be checked dynamically. The interesting part of the demo is that we can do that fairly cheaply and with useful error messages. The code is here. background I'm exploring a style of…

The idea is to explain how lots of different little things in each of the games actually work, down to the level of how they are implemented in the 6502 (Tempest) and 68K Motorola (Tempest 2000) assembler source code. I tried to keep it light and digestible so the book consists of lots of little chapters, each one presenting…
🚀 Read this insightful post from Hacker News đź“– đź“‚ **Category**: đź“Ś **What You’ll Learn**: You've already built the agent. It lives somewhere: a LangChain chain, an Azure Foundry deployment, a Slack bot. Your users live in Teams. Teams is where most enterprise work happens: decisions get made, customers get answered, and projects move forward there. Getting your agent into that context, before you build anything Teams-specific, is already worth doing. It comes down to one pattern in the Teams TypeScript SDK: the HTTP server adapter. You point it at your HTTP server, it registers a messaging endpoint, and your…

This property is useful as an activation function in neural networks, where it introduces non-linearity while keeping outputs bounded, and in audio signal processing, where it provides natural-sounding soft clipping for saturation and distortion effects.In both contexts, speed matters. Neural network inference may evaluate \( tanh…
