CalBridge: Two way calendar sync tool

What it does

Unlike expensive SaaS tools ($8-48/mo), CalBridge is open-source and self-hostable for as low as ~$5/mo on a VPS or totally free if you run it on your machine. Key differences: granular copy controls (choose exactly what syncs), smart filtering by keyword or color before sync happens, true two-way sync with loop prevention, and bounded backfill control. Deploy in one click on Railway.

  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…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
