Show HN: SlideOps – slides from a repo that flag when they drift from the code
I kept generating slide decks about my codebases with an agent, and weeks later they would go stale. Updating them was quite costly (time & tokens), as the agent would have to re-scan the whole repo to re-generate the slides. So I made the slide deck carry its own provenance: SlideOps skill turns a repo into a slide deck, with all references to files carrying exact line range and a hash.<p>Checking is done with standard-library Python: no model calls, no network, and very fast. For example, it distinguishes MOVED (the code shifted) from CHANGED (the content differs). Updating the slides costs tokens, but now the checking part has already given the agent just the relevant context on what exactly needs to be repaired.<p>SlideOps ships as a Claude Code plugin and runs as a plain agent skill in Codex, Copilot CLI and OpenCode.<p>Longer write-up: <a href="https://medium.com/@lukicov/your-documentation-is-a-build-artifact-start-treating-it-like-one-ab48df61b1e0" rel="nofollow">https://medium.com/@lukicov/your-documentation-is-a-build-ar...</a><p>GitHub repo: <a href="https://github.com/glukicov/slideops" rel="nofollow">https://github.com/glukicov/slideops</a>
Show HN: Floe – an open-source plugin for sample libraries – CLAP/VST3/AU
I'm Sam, I make sample libraries (as FrozenPlain). These sample libraries run inside Floe, my audio plugin for Linux, macOS and Windows. It's designed for musicians, composers and producers - typically people involved with film/TV/game scoring or ambient music. I open-sourced it primarily because I'm very fond of this philosophy and I want to open the door for serving a wider audience than just my own libraries.<p>It's totally free, no sign-ups. You'll need a DAW. To try it:
- Download and install Floe: <a href="https://floe.audio" rel="nofollow">https://floe.audio</a>
- Download your choice of free packages: https:floe.audio/packages#community-packages or <a href="https://www.frozenplain.com/product/music-box-suite-free" rel="nofollow">https://www.frozenplain.com/product/music-box-suite-free</a>
- Install the packages using Floe's 'Install Package' button. <a href="https://floe.audio/docs/installation/install-packages" rel="nofollow">https://floe.audio/docs/installation/install-packages</a><p>I'm curious about HN's thoughts regarding the open-source nature, directions I could take for expanding the audience, and the Lua based sample-library it has (<a href="https://floe.audio/docs/develop/develop-libraries" rel="nofollow">https://floe.audio/docs/develop/develop-libraries</a>). Thanks.
Show HN: Markdown Viewer and Editor
I built an online viewer and editor for .md files where the file stays on your machine. Free to use and code is available under MIT License here: <a href="https://github.com/hattray/markdown-editor" rel="nofollow">https://github.com/hattray/markdown-editor</a><p>You can also install it as a Chrome/Edge app so that it works for files on your desktop by double-clicking.<p>Supports standard .md files with formatting, syntax-highlighting for code, table of contents, Mermaid diagrams, LaTeX via KaTex.

Show HN: HN Match Maker – Matching "Who Wants to Be Hired?" With "Who's Hiring?"
Hi!<p>Every month the "Who Wants to Be Hired?" and "Who's Hiring?" Threads come through I would think to myself, "there should be a match maker for these two threads".<p>So I had abacus.ai whip one up. The methodology is pretty simple, data is extracted from posts using an LLM, score matches based on salary, domain experience, remote/onsite, etc., and then eliminate incompatible postings, like 'looking for remote work' and 'onsite only'. The result is two views: jobs-by-user and user-by-jobs.<p>If you've submitted a post to this month's 'Who Wants to Be Hired?", you can find your matching job listings at <a href="https://hnmatchmaker.com/user/:user_name" rel="nofollow">https://hnmatchmaker.com/user/:user_name</a>, for example <a href="https://hnmatchmaker.com/user/G4Vi" rel="nofollow">https://hnmatchmaker.com/user/G4Vi</a><p>---<p>Some observations when looking at the matches pair up right now:<p>Poke around, let me know what you think!<p>Ultimately, I hope this is actually helpful to some folks.
Show HN: Weedout – Safari extension that hides YouTube AI-labeled videos
I'm the developer. I built this because AI-generated conspiracy videos were getting out of control in my own YouTube feed. Weedout is a $1.99 Safari extension for macOS that removes videos YouTube labels “Made with AI” from feed, search, related videos, playlists and Shorts. It uses YouTube's label rather than AI detection, runs locally, and does not catch unlabeled videos.<p>Source for developers who want to fork or build: <a href="https://github.com/masteranza/weedout-for-youtube" rel="nofollow">https://github.com/masteranza/weedout-for-youtube</a><p>Pull requests are not accepted; the repository is for independent forks.
Show HN: Running 104GB Qwen3.8-Flash-Next on 48GB Mac with at ~12 tok/s
I built slotstream, a way to run Qwen3.8-Flash-Next 4-bit on a low-memory mac starting from 16GB, a 125B parameter model that would need 100GB+ memory/RAM, thanks to expert-offloading/ssd-streaming. Easy to install/update, and mac-native using MLX and Swift.<p>It ships with auto-mode, which makes a good tradeoff between memory usage and speed. I'll be implementing and porting the MTP module for speculative decoding next
Show HN: Corporate Mind Games – logic puzzles with a sarcastic corporate theme
I have always enjoyed building and playing puzzles. I am a regular user of NYT Games and LinkedIn Games. I thought it would be fun to create some corporate-themed puzzles as a silly alternative to LinkedIn Games.<p>So, I built Corporate Mind Games. The games are intended to be a little bit sassy and sarcastic, but I hope they are enjoyable and challenging.<p>I was planning to post this on HN last week. However, many years ago, I made a game called Don't Wordle, which unexpectedly appeared on the front page last week. I ended up getting distracted by that, and I also figured it was more appropriate to post this game on HN on a Monday morning given the theme. So here we are.

Show HN: FnScribe – Open-source, offline dictation for macOS
I built FnScribe because I'm pretty privacy concious and wanted a wispr flow-like app that kept everything local and on device. Currently works for Mac (sillicon and intel).<p>It's dead simple. Hold the fn key, speak and release. I use a quantized Wisper small.en model for transcription. It inserts the text into the active application. There's also a hands-free model for longer dictation. Audio transcription is kept in memory. There's no account or transcription history. Clipboard contents are restored after it inserts it. GPLv3, Mac-only, English only..still in alpha. Hope you enjoy it! Would love some feedback.

Show HN: We built the smallest dual-band aircraft tracker
We've been building open source embedded ADS-B receivers for a while, and spent the past 8 months smallifying our existing receiver tech with a new chip from Semtech. Ask me anything about ADSB or hardware manufacturing!

Show HN: Academa – Long-form STEM lecture videos generated by LLMs
Hi HN, we are Sina Atalay and Abdullah Geduk, co-founders of Academa. We are both PhD students.<p>We thought: what if lecture videos were written as code and compiled into video using computer graphics and TTS?<p>Then LLMs could write them, and lectures could be fixed with code edits instead of video production.<p>On correctness: LLMs may make mistakes. But these videos are code sitting in our repository, and we can maintain them. Every report and review becomes a fix in the source, and everyone who watches after that gets the corrected lecture. Every recorded lecture on the internet is stuck with its mistakes. Ours will continuously improve.<p>Each video also comes with an AI chat that understands everything said and shown in the lecture.<p>There is a longer write-up at the bottom of the page.<p>Happy to answer any questions.
