Sunrisewhen – pretty sunrise and sunset times for your area2024 · sunrisewhen.com · ▲34I shared this a little while ago. Since then, I've implemented some feature requests and added a small weather widget. There are also static pages for major cities if you prefer not to use the location-based version. e.g., https://sunrisewhen.com/new-york I know most phones and browsers already provide this kind of info, but it's a fun little project I enjoy keeping alive. cheers
Daylight – track sunrise / sunset times in your terminal2025 · github.com · ▲79I love the sunlight and dread the long, dark winter evenings of Northern Europe. I often look up sunrise / sunset times and count off the days until the darkness is gone. Now I've written a terminal app for this (Mac/Linux) Features: a colorful summary of daylight times for your location; projected change over the coming days; handles NO_COLOR and a ---short flag if you dislike the output format. The location is IP-based but you can override this if you're on a VPN. Just create a terminal alias with the --loc flag. The app supports areas in the arctic / antarctic circle too.…

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.…

OpenSEO▲928Hello! 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…
