I&#x27;ve been working on a little side project that combines Duolingo-like listening comprehension exercises with real content .Every video is transcribed to get much better transcripts than the closed captions. I filter on high quality transcripts, and afterwards a LLM selects only plausible segments for the exercises. This seems to work well for quality control and seems to be reliable enough for these short exercises.Would love your thoughts!

The Myst Graph: A New Perspective on Myst

Dave Täht has died

Last week was big for open source LLMs. We got:- Qwen 2.5 VL (72b and 32b)- Gemma-3 (27b)- DeepSeek-v3-0324And a couple weeks ago we got the new mistral-ocr model. We updated our OCR benchmark to include the new models.We evaluated 1,000 documents for JSON extraction accuracy. Major takeaways:- Qwen 2.5 VL (72b and 32b) are by far the most impressive. Both landed right around 75% accuracy (equivalent to GPT-4o’s performance). Qwen 72b was only 0.4% above 32b. Within the margin of error.- Both Qwen models passed mistral-ocr (72.2%), which is specifically trained for OCR.- Gemma-3 (27B) only scored 42.9%. Particularly surprising given that it&#x27;s architecture is based on Gemini 2.0 which still tops the accuracy chart.The data set and benchmark runner is fully open source. You can check out the code and reproduction steps here:- <a href="https:&#x2F;&#x2F;getomni.ai&#x2F;blog&#x2F;benchmarking-open-source-models-for-ocr">https:&#x2F;&#x2F;getomni.ai&#x2F;blog&#x2F;benchmarking-open-source-models-for-...</a>- <a href="https:&#x2F;&#x2F;github.com&#x2F;getomni-ai&#x2F;benchmark" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;getomni-ai&#x2F;benchmark</a>- <a href="https:&#x2F;&#x2F;huggingface.co&#x2F;datasets&#x2F;getomni-ai&#x2F;ocr-benchmark" rel="nofollow">https:&#x2F;&#x2F;huggingface.co&#x2F;datasets&#x2F;getomni-ai&#x2F;ocr-benchmark</a>

I believe the best way to learn a language is by doing an in-depth project. This is my first Zig project intended for learning the ropes on publishing a Zig package. It turns out to be quite solid and performant. It might be a bit over-engineered.This little library is packed with the following features:<pre><code> - Building dependency graph from dependency data.
 - Performing topological sort on the dependency graph.
 - Generating dependence-free subsets for parallel processing.
 - Cycle detection and cycle reporting.</code></pre>

Hey HN, we’re Daniel and Daniel (the Daniels) from aSim (<a href="https:&#x2F;&#x2F;asim.sh&#x2F;">https:&#x2F;&#x2F;asim.sh&#x2F;</a>). aSim is a mobile app that can generate immediately usable and shareable mobile apps from your phone.Tools like bolt.new and v0 have made it easier to build websites by just chatting with an LLM, but things have been lagging on the mobile side. We’ve always been suckers for well-made mobile apps, but today, it is still extremely difficult to build mobile apps with LLMs on your computer, and nearly impossible to do it from your phone.We built aSim to make it easy to build prototypes, “trinket” apps, or just random fun things all async from your phone. You can check our landing page (<a href="https:&#x2F;&#x2F;asim.sh&#x2F;">https:&#x2F;&#x2F;asim.sh&#x2F;</a>) for some ideas of different types of apps. Hopefully we can bring some life to your side project graveyard, or at least make the graveyard even more numerous.Here’s a demo video of the generation process: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;_3VCl13oMGc" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;_3VCl13oMGc</a>And here are the actual one-shotted apps I made in that video:- <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157003&#x2F;make-an-app-where-i-can-upload-an-image-and-it">https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157003&#x2F;make-an-app-where-i-can-upload...</a>- <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157014&#x2F;make-me-an-app-that-is-a-clone-of-yikyak">https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157014&#x2F;make-me-an-app-that-is-a-clone...</a>- <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157006&#x2F;make-me-a-chess-timer-app-for-in-person-chess">https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157006&#x2F;make-me-a-chess-timer-app-for-...</a>All of our app generations also get access to a set of APIs that help get the ball rolling on some basic functionality. These APIs range from LLM usage and image generation to having shared state with your friends, and globally among all users. We’re always on the lookout for new API integrations (i.e. Spotify and Maps) so please let us know if you need any!We’ve had a small cohort of beta users that have been making what we think are some pretty cool apps. Here’s some of our favorites:- Pokemon-style Gacha Game - <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@evan&#x2F;s&#x2F;126948&#x2F;elves-vs-monsters">https:&#x2F;&#x2F;asim.sh&#x2F;@evan&#x2F;s&#x2F;126948&#x2F;elves-vs-monsters</a>- OpenStreetMap stats: <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@lake&#x2F;s&#x2F;104102&#x2F;osm-stats">https:&#x2F;&#x2F;asim.sh&#x2F;@lake&#x2F;s&#x2F;104102&#x2F;osm-stats</a>- Star wars idle game: <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@jojaspero&#x2F;s&#x2F;29102">https:&#x2F;&#x2F;asim.sh&#x2F;@jojaspero&#x2F;s&#x2F;29102</a>- Find your Meyers Briggs - <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@typewhisperer&#x2F;s&#x2F;135964&#x2F;jung-mirror">https:&#x2F;&#x2F;asim.sh&#x2F;@typewhisperer&#x2F;s&#x2F;135964&#x2F;jung-mirror</a> (&lt;-- just for fun, you don’t have to believe in MB :))- AI Tic Tac Toe - <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@hashmelons&#x2F;s&#x2F;105561&#x2F;ai-tic-tac">https:&#x2F;&#x2F;asim.sh&#x2F;@hashmelons&#x2F;s&#x2F;105561&#x2F;ai-tic-tac</a>Behind the scenes, we’re generating a modified version of Typescript React Native that can be parsed and compiled into simpler instructions that can be sent to mobile devices on the fly. We’ve ripped out some parts of the TSC library, as well as lean heavily on AcornJS to massage the (mostly usable) LLM code into something that can actually be run. We have a bunch of static analyzers, as well as leaning on web runtimes to catch runtime errors (as well as take screenshots), though at the very end of the day, we lean the most on our users to play around with their creations and remix them into something great.It’s currently completely free to use, so we hope you check out aSim at <a href="https:&#x2F;&#x2F;asim.sh&#x2F;">https:&#x2F;&#x2F;asim.sh&#x2F;</a> and enjoy it as much as we have while building it! Let us know what features you’d like to see and any problems you have with your generations.

Hey HNI built svggles (npm: interactive-illustrations), a React utility that makes it easy to add playful, interactive SVGs to your frontend.It supports mouse-tracking, scroll, hover, and other common interactions, and it&#x27;s designed to be lightweight and intuitive for React devs.The inspiration came from my time playing with p5.js — I loved how expressive and fun it was to create interactive visuals. But I also wanted to bring that kind of creative freedom to everyday frontend work, in a way that fits naturally into the React ecosystem.My goal is to help frontend developers make their UIs feel more alive — not just functional, but fun. I also know creativity thrives in community, so it&#x27;s open source and I’d love to see contributions from artists, developers, or anyone interested in visual interaction.Links:
