[Other] Show HN: Dashboard tracking all GitHub PRs and analyzing Code Agent activity Hi HN,<p>We are researchers from ETH Zurich interested in the real-world adoption and impact of Code Agents.<p>To measure this, we built a dashboard, scraping all public PRs on GitHub, analyzing which are created by different code agents (Codex, Jules, Copilot, Devin, etc.), and measuring their merge rates, sliced by various repository and PR characteristics.<p><a href="https:&#x2F;&#x2F;insights.logicstar.ai" rel="nofollow">https:&#x2F;&#x2F;insights.logicstar.ai</a><p>Since mid-May, we&#x27;ve analyzed over 10 million PRs and already found some interesting trends:<p>Usage is high, but shallow. Agents submit ~7% of all PRs overall, but only ~1–2% on popular repos. Most activity is in low-star or experimental projects.<p>Merge rates vary drastically. On low-traffic repos, some agents get 90%+ of their PRs merged. On popular projects, that can drop to &lt;25%.<p>Pre-review helps. Agents that require human-in-the-loop review (e.g., Jules, Codex) have 30–50% higher merge rates than Copilot-style fire-and-forget PRs.<p>Bias toward new code. Agent PRs mostly add code. Refactorings and deletions are rare.<p>If you have ideas for what other characteristics we should look at let us know or play with the code yourself

[Other] Show HN: Jukebox – Free, Open Source Group Playlist with Fair Queueing Hey HN,<p>I built Jukebox because I got frustrated with group music apps and Spotify’s limitations (not everyone has Spotify, and collaborative playlists are still too easily dominated by one person). Jukebox is a web app that lets you create a group queue—anyone can join via link, add YouTube songs, and the system automatically rotates songs so everyone gets a fair turn (no more playlist hogs).<p>Web-based, no accounts, no installs.<p>Drop in a YouTube link or search and add music instantly.<p>Songs rotate in round-robin order (so even if one person adds ten songs, nobody else is skipped).<p>Entirely open source (MIT), self-hostable with Docker, privacy-friendly.<p>Live demo: <a href="https:&#x2F;&#x2F;jukeboxhq.com" rel="nofollow">https:&#x2F;&#x2F;jukeboxhq.com</a><p>Code: <a href="https:&#x2F;&#x2F;github.com&#x2F;skeptrunedev&#x2F;jukebox">https:&#x2F;&#x2F;github.com&#x2F;skeptrunedev&#x2F;jukebox</a><p>I made this as a stress-relief project while pivoting my actual startup (Trieve) and used it to practice UI&#x2F;UX (neo-brutalist design, drag-and-drop), plus experiment with AI pair coding.<p>Would love your feedback or feature ideas!

[Other] Show HN: Smart Switcher - data driven tool to improve the window switching Hello, my name is Andrew. I&#x27;m an indie developer and I&#x27;m excited to release Smart Switcher for Windows 10&#x2F;11. I&#x27;m looking for feedback on the overall project and the application itself.<p>I built this because I couldn&#x27;t find a window switching&#x2F;management solution that worked for me. I tried all kinds of different solutions, virtual desktop extensions, obscure GUI window managers, you name it. Overtime I realized I wanted something that prioritizes one window at a time, is keyboard driven with has minimal if no GUI elements. I figured this part out, but knew something was missing. I had my eureka moment when I realized I could combine my switching method with a prediction algorithm. This led to the creation of Smart Switcher.<p>Smart Switcher is a data driven window switcher aimed at improving the overall window switching experience. It logs data on your windows switching, then a prediction algorithm analyzes this data and uses it to predict which window you would want to switch to next. When you need to switch windows, you press the switch shortcut to switch to the next predicted window. If this isn&#x27;t the window you wanted, press the override shortcut to switch to the next most likely window. You can press the override shortcut as many times as needed until you arrive at your desired window.<p>It’s a paid app with a demo and trial version. There is a introductory discount and some additional discount tiers for early adopters.<p>Any feedback is appreciated! Thanks!

[Other] Show HN: OffChess – Offline chess puzzles app Hi HN!<p>I&#x27;m the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet.<p>Why? Well, my Wi-Fi is terrible in the bathroom—and that&#x27;s where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction. So I built OffChess.<p>OffChess is an iPhone&#x2F;Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in 1&#x2F;2&#x2F;3&#x2F;4&#x2F;5, tactics like pins&#x2F;forks&#x2F;skewers, or openings like Sicilian&#x2F;French, etc). You gain or lose points based on how you perform, so there&#x27;s a light rating system to keep things engaging.<p>No accounts, no tracking, no monthly subscriptions, no internet required. Just pure, old-school tactical chess training, wherever you are.<p>You can check out the iPhone&#x2F;iPad app at <a href="https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;chess-puzzles-offchess&#x2F;id6744736661?platform=iphone">https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;chess-puzzles-offchess&#x2F;id67447...</a> or the Android app at <a href="https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.offchess">https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.offchess</a><p>Would love feedback, bug reports, or suggestions.<p>Thanks!
