Show HN: Synchrotron, a real-time DSP engine in pure Python
Show HN: Synchrotron, a real-time DSP engine in pure Python Yes, Python.<p>I can already hear the screams from the rafters telling me how terrible of a choice Python is - but in my case, I valued modularity, extensibility, <i>hackability</i> over raw performance. (It was also a challenge to myself to see how far I can get without referencing existing implementations)<p>Synchrotron processes nodes: simple Python classes with typed I/O and a render() method for processing. It can be as concise as 5 lines:<p><pre><code> class IncrementNode(Node): input: StreamInput output: StreamOutput def render(self, ctx): self.out.write(self.a.read(ctx) + 1) </code></pre> Nodes can then be spawned and linked programmatically or in the graphical editor. Synchrotron handles the rest at runtime. Besides the web UI, you can also interact with the engine via Python, REST, DSL, or standalone TUI.<p>Currently you can build synths, FX chains, MIDI instruments, arpeggiators, controllers, or just mess about with sound :><p>Editor: <a href="https://synchrotron.thatother.dev/" rel="nofollow">https://synchrotron.thatother.dev/</a> Source: <a href="https://github.com/ThatOtherAndrew/Synchrotron" rel="nofollow">https://github.com/ThatOtherAndrew/Synchrotron</a><p>It's still experimental (and my first ever shipped project), but I'd love feedback from people who tinker with audio/DSP/live coding. Docs are terrible currently, but that's my next big goal!

Show HN: A GitHub Action that quizzes you on a pull request
Show HN: A GitHub Action that quizzes you on a pull request A little idea I got from playing with AI SWE Agents. Can AI help make sure we understand the code that our AIs write?<p>PR Quiz uses AI to generate a quiz from a pull request and blocks you from merging until the quiz is passed. You can configure various options like the LLM model to use, max number of attempts to pass the quiz or min diff size to generate a quiz for. I found that the reasoning models, while more expensive, generated better questions from my limited testing.<p>Privacy: This GitHub Action runs a local webserver and uses ngrok to serve the quiz through a temporary url. Your code is only sent to the model provider (OpenAI).
Show HN: Linux CLI tool to provide mutex locks for long running bash ops
Show HN: Linux CLI tool to provide mutex locks for long running bash ops Been exploring claude and spec-based coding, I think it turned out fairly successful. It's just a simple unix-style tool that gives you a single command to use in bash scripts to simplify mutex or semaphore locking of execution.
