Show HN: A beautiful and local-first PDF reader for studying dense things Recently, I found myself having to read the book &quot;C++ primer&quot; and I just couldn&#x27;t do it. Maybe my attention span is too little now with Claude and Codex, maybe I&#x27;m lazy... but I just couldn&#x27;t get myself to focus.<p>While reading, I needed something to do. I wanted to talk to the text, I wanted to leave notes, I wanted to use to use my keyboard to quickly flip through pages.<p>The only good available option on a Mac was &quot;Preview&quot; and it was ok, but definitely not there. So I built Quincy primarily for myself.<p>With it you can - &quot;Talk&quot; to the page you&#x27;re reading, create a quiz about the page, and get a good summary - &quot;Read&quot; the page out-loud. Have your Mac read to you while you follow along. This helps with comprehension. - Copy text (to paste into an LLM), leave notes, bookmarks, etc.... - Anything else you&#x27;d want with a nice PDF reader<p>It&#x27;s fully local. No cloud-sync (yet). All LLM calls are based on your keys. And TBH, you don&#x27;t even need to use the AI features for this to be useful.<p>Try it out. Let me know what you guys think. This has been a quick project, so very rough around the edges. I plan on keeping it going (still haven&#x27;t finished my book), and potentially open-sourcing down the line.

Show HN: Resonate – Low-latency, high-resolution spectral analysis Last April I shared about my Resonate project here (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43694157">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43694157</a>)<p>A lot has happened since: the work I presented in much more detail at last June&#x27;s International Computer Music Conference (ICMC) got best paper award. I also gave a talk at the Audio Developer Conference in Bristol last November, the video is on YouTube).<p>This year&#x27;s work, which I recently presented at this year&#x27;s ICMC, starts with known techniques from the phase vocoder literature to build self-tuning filter banks that extract very efficiently the frequency components that are actually present in the input signal. Overview on the project website, more details in the papers, including applications to super-resolution spectrograms and re-synthesis experiments.<p>As many people have pointed out, none of the techniques I have used are new (some of them even have different names across different fields), but I haven&#x27;t seen them applied together in this way, and to me the results are incredibly satisfying and sometimes look magical. See for example this demo: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;LasdoIJJkw8" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;LasdoIJJkw8</a><p>Of course the best way to experience in person is through the free demo app: <a href="https:&#x2F;&#x2F;alexandrefrancois.org&#x2F;Oscillators" rel="nofollow">https:&#x2F;&#x2F;alexandrefrancois.org&#x2F;Oscillators</a><p>Looking forward to feedback from the community!

Show HN: Ccgs – Collaborative Claude Code sessions, stored in Git branches My team uses Claude Code daily, and the sessions have become some of the most useful artifacts we produce. But they&#x27;re trapped in ~&#x2F;.claude&#x2F;projects&#x2F; on whichever laptop they happened on. There&#x27;s no good way to hand a colleague &quot;the session where I untangled the migration&quot; so they can claude --resume it and keep going from where I left off. Enter ccgs: Share Claude Code sessions through an orphan branch (@ccgs&#x2F;&lt;name&gt;) in your existing repo&#x27;s remote<p>- Session files carry the author&#x27;s absolute paths. On pull, ccgs rewrites the working dir back to your path so resume actually works — surgically editing only the structural cwd field, not a blind find-and-replace that would happily corrupt the transcript.<p>- Everything goes through git plumbing (hash-object&#x2F;commit-tree&#x2F;update-ref) against a throwaway index. It never touches your working tree, index, or current branch, and it&#x27;s fine with a dirty tree. It will not git checkout something behind your back.<p>To try it without installing: `npx claude-git-sessions`. This also incidentally allows you to move a directory and carry the claude code transcripts with it (just push first, then move the directory, then pull)<p>IMPORTANT CAVEAT: Unless you have a very good security hygiene, your Claude Code sessions are likely full of sensitive information such as environment secrets. Use with caution and avoid using on public repositories. Branches used by ccgs are prefixed by `@ccgs&#x2F;` so you can easily filter them out.<p><i>This project was written by and with Claude Code.
