What it does
Deep inspection for video files. No spreadsheets. No upload. Just analysis.
Empowering People through technology lore.
Deep inspection for video files. No spreadsheets. No upload. Just analysis. We render the actual geometry of the video frame. Instantly spot pixel aspect ratio mismatches, letterboxing, and pillarboxing without calculating SAR/DAR manually. Bitrate quality estimation based on resolution and codec efficiency. Powered by a local FFmpeg binary. Zero latency. Zero data egress. Requires 64-bit processor. FFmpeg is downloaded automatically on first run. LENS is a local desktop application that analyzes video files using FFmpeg and presents technical metadata in a visual, human readable format. No. All video analysis happens entirely on your local machine. Files are never uploaded, streamed, or…from pext.org

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
