Multi-display screen sharing with CoScreen

In plain words

CoScreen 5.0 is a screen-sharing tool for developers and teams that enables simultaneous multi-directional screen sharing from multiple displays at once. Built with a Rust-based engine for fast window compositing and streaming, it allows users to selectively control what they share. The software is designed for pair programming, debugging, and collaborative problem-solving where teams need to view and work with code, commands, graphs, and logs together. It is now part of Datadog.

In the maker’s words, at launch

Good to be back on HN with all-new CoScreen, a little more than 3 years after it launched over here! With CoScreen 5.0, you can now share your windows from multiple displays at the same time, a long standing request by our most avid users and impossible in other apps. It also has a lightning-fast, Rust-based window…

  Talanoa▲337

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT▲688

  I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
