The Beavis Ultrasound PnP is an open source replica of the Gravis Ultrasound Pnp. Unlike other clones, this design includes the entire schematic as well as the reverse-engineered source code of the GAL. If you want to build this board, first make sure you have an AMD InterWave chip, the AM78C201. The design of the card is quite simple since essentially all sound card functionality is built into the AMD…

🔥 Check out this trending post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: The most important control is evidence stance: from skeptical (~70,000 QALYs — each effect weighted by how well its study identifies causation) to credulous (~200,000 — every cited effect at face value). That gap, not the dollar figure, is the real uncertainty.

🔥 Read this insightful post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Enhancements The graph generation procedure we've discussed works well enough for explaining the algorithm, but there are many ways in which it can be improved. These enhancements make the algorithm use less CPU and memory, and allow it to handle more cases. Let's take a look at a few. Obstacles that touch Perhaps you picked up on it—none of the circular obstacles in the examples given so far have overlapped or even touched. Allowing circles to touch makes the pathfinding problem a little, but not…

I had this sudden itch and I wanted to play around with hardware. I don't really have much experience in this space, besides working on firmware for an IoT company over a decade ago, but I've written tons of software over the years. I was very surprised how quickly I was able to get the built-in LEDs to blink with Arduino IDE and some help from…

Claude Code Sends 4.7x More Tokens Than OpenCode Before Reading Your Prompt

💥 Discover this awesome post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: We put Claude Code and OpenCode on the same model, the same machine, and the same tasks, then examined everything sent and received.Claude Code is far hungrier:When we asked both harnesses for a one-line reply, Claude Code used roughly 33,000 tokens of system prompt, tool schemas, and injected scaffolding before the prompt even arrived. OpenCode used about 7,000.Claude Code is far more cache inefficient:OpenCode's request prefix was byte-identical in every run we captured; it paid to cache its payload once per session and read it…
