What it does

You finish a great book, feel changed by it, and a month later, you cannot name three things from it. Kern fixes that. Add a book by title and it creates a small deck of recall cards. Non-fiction gets the core ideas. Fiction gets characters, turns, and the moments that mattered. No highlights, no note exports, no writing cards yourself. Reviews come back on a spaced schedule timed to catch each one right before you forget it. Works for paper and library books. No streaks. Two books are free.

Stop forgetting what you read. Kern turns any book you

You spent ten hours reading that book. A month later, three ideas survive. Kern turns any book you've finished into sharp, swipeable flashcards — then spaced repetition brings the ideas back right as they start to slip. ★★★★★ “Exactly what I was looking for.” Mariom753 · App Store No uploads, no highlights, no homework. If you finished it — paper, Kindle, audiobook, the one from 2014 — Kern can keep it alive. Type the title. That's the whole job. No EPUBs, no exporting highlights, no note-taking system to maintain. Kern writes a deck of original cards from the book's key ideas, examples and surprising claims — like a smart friend telling you the best parts. Ready in seconds.…from kern.cards

    I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

    Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  • A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

    Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
