What it does
QR codes can be slow, and lines build up fast. Signtone replaces static codes with audio sign tones—a frictionless audio QR technology that lets organizers connect with any place in seconds. Whether you’re hosting a conference, running a retail promo, or radio ad, all you need is a speaker. Broadcast: The organizer plays a Signtone over any standard speaker. Detect: The Signtone mobile app picks up the Signtone in seconds. Connect: Users tap once to check in, claim deals, and join waitlists.
Walk into any venue, hear the tone, and connect instantly. Get schedules, retail deals, waitlists, networking profiles, and more—all in a single tap. Users see store-specific discounts in one convenient place before they head out. After the first sign-up, users can check today's offers anytime without waiting for extra notifications. Keep the latest retail offers easy to scan from the app home, ready before the next store visit. Stores can announce top deal users or winners based on who engages with their offers most. Signtone plays at the entrance. Attendees check in as they walk in. No desk, no queue. Name, email, company, and LinkedIn — captured automatically at registration. Share…from signtone.app

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…
