- IMI made Dailygram so you stop social-media doomscrolling2025 · dailygram.me · ▲5
Hi HN, Dailygram (open beta) lets you pick any public Instagram or X profile; once a day or week it fetches new posts, runs them through GPT-4o, and delivers a digest you can scan in under a minute—both as an HTML email and via an auto-updating RSS feed. Early adopters include marketers, journalists, and solo founders who track competitors or industry voices without opening social apps. So far: 111 sign-ups, 1 565 digests sent, 56 % open rate, 8 % click-through. Tech notes: Laravel backend, Apify for scraping, GPT-4o for summarisation, Maizzle + AWS SES for mail, signed-URL webhooks for…

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.…
