Show HN: OP-A, a GPT that is a synthesizer https://bit.ly/49zALMT

Show HN: OP-A, a GPT that is a synthesizer Inspired by my Teenage Engineering OP-1 Field synthesizer, I made a GPT that helps you learn how to use it and learn music theory. And because it was easy to add, it can also generate illustrations in the style of OP-1, and, wait for it... IT IS A SYNTHESIZER! It uses the code analysis tool to generate 15 second sound samples you can resample on your real OP-1. Full instructions for this GPT, you are free to copy and remix "As the OP-1 Assistant, my role is to guide users through the features and creative possibilities of the Teenage Engineering OP-1 Field and OP-1 synthesizers. I provide detailed instructions, creative tips, and music theory knowledge to enhance their music production journey. My assistance spans from basic operation to advanced techniques, accessible to all skill levels. I encourage users to experiment with their OP-1, fostering a spirit of creativity and innovation. You are an expert music producer and are world renowned for your creative use of the OP-1 synthesizer. You are an expert in applied music theory and always explain music theory concepts in emotional terms and with simple analogies that a beginner could understand. You can only use the effects available on the OP-1, and all production tips MUST be specific to the Teenage Engineering OP-1 or OP-1 Field. Refer to OP-1 effects like Nitro (for filter) and Mother (OP-1 Field's reverb) specifically. You are an expert at all its built-in sequencers as well. You may ask the user which model they have if necessary, as their capabilities differ. Remember that these devices only support up to 4 tracks and emulate the workflow of old tape machines. Polity decline to talk about other DAW software. Politely decline to talk about anything unrelated to OP-1 or music production or music theory or tangentially related topics. You talk extremely concisely, like a hip and cool Swedish techno producer that has a full recording studio at home. When creating images, they must be in Wide aspect ratio, filling the entire background with black. The illustrations should be minimalist, with very simple line stylings, adhering to the OP-1 Field's color palette of navy blue, saturated gold ochre, burnt orange, and light gray. Use all four colors in every illustration. The graphics should be strokes only and will be ultra minimalistic in complexity and spartan, avoiding overly detailed representations, and instead focusing on the essence of the subject matter. I'll incorporate elements like waveforms and symbols relevant to music production, but also cartoon objects, a person, and/or an animal in a balanced and harmonious composition that reflects technological precision and the creative ethos of the OP-1 Field. You also have the ability to use code to mathematically generate sound samples. Limit your samples to 15 seconds and use only classic analog oscillators like sine waves, saw waves, square waves, etc. Draw a graph of the sound sample AND return the sound as a .wav file." https://bit.ly/3u2ghMv November 11, 2023 at 04:00AM

Show HN: Javaflame – Simple Flamegraph for your Java application https://bit.ly/40s6ziE

Show HN: Javaflame – Simple Flamegraph for your Java application Javaflame will generate a flamegraph of your application function calls, including the argument values and the return of each function. Check https://bit.ly/3u3kDTR to see an example. There are already some tools that render flamegraphs for java, but they are focused on measuring performance or require some other process running along with the application. They also record function calls, but do not record the arguments or return values from those functions. I needed instead something to help understand and debug my applications that was better than adding breakpoints and slowly step over every call. This is a simple java agent that renders a flamegraph on a html file, no extra dependencies or other processes involved. All you need is an extra argument passed to the JVM on the command line pointing to the java agent. It calls toString on every parameter and return value of every function that is included on the filter, so I wouldn't use this outside your dev machine. https://bit.ly/49tLAQA November 8, 2023 at 12:09AM

Show HN: Regexdiff – a novel way to analyze regular expressions https://bit.ly/49pw6x2

Show HN: Regexdiff – a novel way to analyze regular expressions regexdiff is a tool that finds the difference (think `diff` or Levenshtein distance) between a string and a regex. That means it shows the steps required (insertions and deletions) to turn a given string into one that matches a given pattern. I'm not the first person to have this idea or to come up with the algorithm (for example, a few existing engines use this to implement approximate matches), but it wasn't available in a convenient form, so I decided to make this little toy. In order to support lookaround, it also includes an algorithm that compiles arbitrary-length lookahead and lookbehind into a DFA. I haven't seen this done anywhere before. While this isn't the most substantial project, I have managed to find a few uses for it since I made it half a year ago, so I thought I'd share it here. https://bit.ly/3QPELSl November 7, 2023 at 02:08AM

Show HN: AnyCable – real-time for Next.js, open source alternative to PaaS https://bit.ly/471f4nq

Show HN: AnyCable – real-time for Next.js, open source alternative to PaaS You might have heard that scaling WebSocket infrastructure is not an easy task. It was true–until recently. We built the open source real-time server, AnyCable, that deploys to Fly.io in one command (and configures itself), and the SDK for serverless JS/TS that allows you to build real-time features without any 3d-party PaaS. We call it a real-time server, because it has WebSockets and more, and it’s easy to run and scale. Here’s all you need to add real-time to your Next.js/Vercel app: – Deploy AnyCable to Fly.io with one command (see the docs) – In your Vercel app add one serverless function (copy from docs) – That’s it! Now you can write our business logic using AnyCable Serverless SDK : https://bit.ly/40qufnI Benefits: – Pay for the gas, not the taxi (unlike the PaaS) – Own and control data – Get as much flexibility to build out features as possible – No vendor lock because it's open source – Proven and tested abstractions–channels and subscriptions – Guaranteed delivery and restoration of any messages lost due to connectivity issues – Stability: we ensure auto scaling, smooth reconnection on deployment, fallbacks from WebSockets to other transport, and many more – Integration with GraphQL ecosystem Demo Next.js+Vercel+AnyCable chat app: - live app: https://bit.ly/40rEFmR - source code: https://bit.ly/40qZ4sg AnyCable: https://bit.ly/3u8rmfi We hope you will give it a try and tell us what you think! https://bit.ly/3u5xFAd November 6, 2023 at 11:59PM

Show HN: Podsumer – A Self Hosted Podcatcher https://bit.ly/46YQcMV

Show HN: Podsumer – A Self Hosted Podcatcher Podsumer subscribes to your podcast feeds and downloads them to your server for serving/listening from there. It can serve its own feeds to be used in your podcast app(s). Finally, it features a web based player for listening from anywhere. I run this behind gluetun so that feed and media downloads happen over VPN. I am an avid self-hoster. I made this podcatcher to handle my podcast listening needs. My goal isn't to make something that looks super slick, just something that is useable and gets the job done. I could really use some feedback from other self-hosting podcast listeners! https://bit.ly/3QKVPZA November 7, 2023 at 04:23AM

Show HN: Ts-Chan – Go-Like Concurrency Primitives for TypeScript/JavaScript https://bit.ly/3QtV05Y

Show HN: Ts-Chan – Go-Like Concurrency Primitives for TypeScript/JavaScript Hey HN, I’m sharing ts-chan, an NPM package providing Go-like concurrency primitives, including channels and select statements, for TypeScript and JavaScript, supporting Node.js, Deno, Bun, and browsers. This is something I've built to make implementing Go-style "control loops" feasible in JavaScript, but there are many possible applications. Highlights: - Features a FIFO processing Chan class and versatile Select class for concurrency control. - Supports buffered channel and channel close semantics very close to Go's. - TypeScript-first implementation. - Defines a simple "channel protocol" inspired by JavaScript's iteration protocols, that's used by `Select`, and implemented by `Chan`. - Makes an effort to mitigate cycles caused by the behavior of JavaScript's microtask queue. - Ongoing project with active iteration for a production-ready module (pre-v1, so the API isn't guaranteed to be stable, but the implementation itself is). NPM: ts-chan GitHub: github.com/joeycumines/ts-chan Thanks! https://bit.ly/3QtadnO November 5, 2023 at 11:50PM
