  The Coinbase FOMO Calculator2022 · vidacode.github.io · ▲108

  Made this using Power BI and the Crypto Watch API. Started making this in November 2021, but never got around to publishing it, so that is the reason for the 'FOMO' in the title - probably a good thing if you 'missed out' on the crypto hype late last year. Now it serves as a way to see how much you 'saved' by not putting in money. Hope someone finds it fun!

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
