    I love the looks and UX of the Google calendar. But I wanted to have a version I could use more freely in my own projects, still looking similar to the one from Google.

    Hi, I am Krishna Thota. I am building an open source integration and data platform(https://cptn.io). The product is MIT licensed and the repo is at https://github.com/cptn-io/el-cptn. I have started on my startup journey an year ago and launched a monitoring platform called DevRaven. Unfortunately the product did not takeoff as expected. That story is for another day. But during the course of building the product, I have built several integrations leveraging MQs and Cloud Functions. While building and deploying Cloud Functions for happy paths is easy, I had to…

    Hi Fellow Hackers! I'm happy to share with you KittyCal, an installable calendar web app I made over the past two months. Existing calendar apps often focus on scheduling and require many steps to create one event. KittyCal, on the other hand, removes hourly scheduling and keeps everything on one screen. How does it work? Just enter your email address, and we will send you a pair of calendar links (blue and red). There is no login process, click the magic link or scan the QR code to access your calendar. You can then add the page to home screen and use it like a native app. Last year, I…

    Hey Hacker News! To test implementing AI (and paywalls tbh) in software for the first time, I made this simple calendar creator (no mail address required) that lets a person create a calendar based on his needs and availability and export it to his calendar app, pdf or receive a daily newsletter with his daily tasks (and more). After wrestling with different models (f.e. with huggingface) and encountering different problems, I decided to use ChatGPT's models, tune them a little and see how the result works out. ChatGPT's low price enables me to give users the opportunity to create calendars…
