What it does
Define a region of your screen to be shared from your ultrawide or high resolution monitor, preventing the inevitable "can you zoom in?" that comes with sharing the entire screen. Define any size region to share, move apps in and out of the region seamlessly, resize the region on the fly, set a default region and invoke with a keyboard shortcut for quick and easy sharing. Blur for privacy. Scaled presenter view displays the content your viewers are seeing. Integrated annotations and whiteboard.
Share part of your screen on Mac. RegionMirror shows a selected region as a normal window in Microsoft Teams, Zoom, Slack, Webex, Google Meet, or Discord — readable for your audience. Made for ultrawide monitors. Free trial.
RegionMirror lets you share a portion of your screen as a normal window in Microsoft Teams, Zoom, Slack, Webex, Google Meet, Discord, and other meeting apps. Made for ultrawide and large high-resolution displays: your audience sees a crisp, readable view of just the region you choose. Free 7-day trial · $19.99 one-time purchase · No subscription Share your whole 49 inch display and everything shrinks to specks for your audience — cue the "can you zoom in?" requests. Share a single window and you're stuck stopping and restarting every time you switch apps. RegionMirror shares a region instead: readable for them, flexible for you. Drag out the area of your screen you want to share — or press…from regionmirror.com

RaybeamMay 2026 · raybeam.live · ▲209Problem A few years ago I got my first ultra-wide monitor. It was a 49" Samsung monitor. I work as a software engineer, and in my line of work I need to screen share a lot. This almost immediately became a problem due to the size of the monitor. I would either need to get a second display just for screen sharing, share one window at a time (which required me to constantly stop/start sharing to select the new window), or share my entire screen making it difficult for other participants in the call to see what I'm doing due to the size of my display. I wanted a solution to this. At the…

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…
