[Other] Show HN: I made a generative online drum machine with ClojureScript After two years of development, I&#x27;m super excited to release Beat Maker! This is my take on what I hope is the best free, web-based drum machine.<p>My goal was to build something that was not only fun and easy to use for beginners but also powerful enough for serious producers. I did extensive research on existing drum machines, analyzed their UX, and tried to build something that adds something new.<p>It&#x27;s a nearly 100% client-side app, written in ClojureScript, and is a PWA so you can install it to your home screen for an app-like experience.<p>Besides the standard grid editor, Beat Maker has some unique features that I think HN readers might find interesting:<p>- Procedural sample generation. One annoying thing about writing beats is searching through folders full of samples. I wanted to improve this and so I added the ability to generate new samples with a single click, giving you an infinite supply of unique drum samples. * Generative beat creation. If you&#x27;re looking for inspiration, Beat Maker can generate entire patterns for you as a starting point. You can then edit and tweak the beat to your liking. Great for solving the &quot;blank canvas&quot; problem and giving you something good to start from. * Advanced export options. This is where it really shines for producers. You can export your work as: * A standard WAV loop * Individual stems (ZIP) * A MIDI file * A ZIP file of all your samples as WAVs * A SoundFont (.sf2) drum kit from your generated samples * An Impulse Tracker (.it) file for use in trackers like Renoise, OpenMPT or a Polyend * Pocket Operator&#x2F;Volca sync. It can output a sync signal on the left audio channel to sync with these hardware devices for perfect timing. * Per-Note FX. You can add effects like volume slides, repeats, and start volume changes to individual notes for more complex drum phrases incorporating flam and roll.<p>As an old school tracker guy, I&#x27;m particularly excited about the Impulse Tracker export mode. I was surprised to discover how many DAWs (including hardware like Polyend) can import this format. Of course, you can also pull up Impulse Tracker on DOSBox, or the more modern re-implementation, Schismtracker for that retro experience.<p>By the way, the beat generator feature is not trained on any artists or anything like that. It&#x27;s an algorithm I built from scratch myself.<p>The audio engine is built on a declarative audio graph (using `virtual-audio-graph`), inspired by React&#x27;s virtual DOM, which makes managing the Web Audio API much cleaner. If you&#x27;re building web based audio apps I highly recommend checking out this library.<p>I&#x27;d love for you to try it out and let me know what you think. Feedback (and the inevitable bug reports) most welcome! Thank you!<p>P.S.

[Other] Show HN: I built a tool to find trading signals that aren't just random luck Hi HN,<p>I&#x27;m a solo dev and for the last few months I&#x27;ve been building Hikaro, a tool to find statistically significant trading signals for [e.g., US equities, crypto, forex].<p>I built this to solve my own problem: I was tired of backtests that looked great on paper but failed in practice. Simple metrics like &quot;win rate&quot; can be misleading, so I wanted a way to quickly tell if a signal&#x27;s performance was genuine or just noise.<p>Hikaro ingests daily market data and runs statistical analysis on various trading signals. The goal is to surface signals with strong properties, like:<p>Low p-value: Evidence that the performance is not a random fluke. High Sharpe Ratio: Better risk-adjusted returns. Healthy &#x27;Core Performance&#x27;: The average return after removing the single best outlier trade, for a more conservative view. Other key metrics like Profit Factor and Max Drawdown that you can filter by.<p>I&#x27;m looking for my first users and would love your feedback. I&#x27;m offering a 30-day free trial of the Pro plan (which includes Telegram alerts) with no credit card required.<p>I&#x27;ll be here all day to answer any questions. I&#x27;m especially keen to hear feedback on the concept and the metrics.<p>Thanks, HN!

[API/SDK] Show HN: Pbar.io – Distributed progress bars that work in terminals and browsers I built pbar.io because I was tired of SSH&#x27;ing into servers to check if my data processing scripts were still running, or worse, having them finish&#x2F;crash without knowing.<p>It&#x27;s a simple REST API that lets you create and update progress bars from anywhere. The same progress bar can be viewed as terminal output (with ANSI colors), in a browser, or consumed as JSON.<p>I&#x27;m actually tracking this HN discussion with pbar. The progress bar increases with each comment - watch it live as we discuss!<p>Web: <a href="https:&#x2F;&#x2F;pbar.io&#x2F;Y8yg3BG" rel="nofollow">https:&#x2F;&#x2F;pbar.io&#x2F;Y8yg3BG</a> Terminal: curl <a href="https:&#x2F;&#x2F;pbar.io&#x2F;api&#x2F;bars&#x2F;Y8yg3BG" rel="nofollow">https:&#x2F;&#x2F;pbar.io&#x2F;api&#x2F;bars&#x2F;Y8yg3BG</a><p>More features that emerged from my own use cases: - Hierarchical progress bars (parent bars auto-aggregate children) - Python package (pip install pbar-io) that wraps tqdm - just swap the import - QR codes to monitor progress on your phone while away from desk - No auth required for quick prototypes<p>Curious what use cases you might have for this!
