How did people like dev/hack/day?

DHD is easily one of my fav events of the year. 🤩 I was amazed by the abundance of excellent content and building that took place during the dev/hack/day. Getting all these legendary hackers and builders in one meatspace to exchange ideas, learn and hang is gods work. 🙏

The dev/hack/day was the most insanely dense pre-event to a conference ever. The quantity and quality of attendees were outstanding, and I cannot wait for this year's edition.

You can go to BTC Prague and listen to what you want to hear. Or you can spend one extra day to go to the dev/hack/day and actually learn something about the tech. Doesn't matter if you think you're a "newb" or you're not technical. Challenge yourself! I didn't let my fine arts degree stop me.

The dev/hack/day was the best part of last year's conference: highly technical, low noise, great location. 10/10 would go again!

The dev/hack/day was a high signal event for builders in the bitcoin ecosystem and a great opportunity to geek out with shadowy super coders.
