Holochain — A new way of thinking about society and distributed systemsHolochain is a framework for building peer-to-peer applications, like Ruby on Rails but it runs your app directly on your device instead of on a server. When I was introduced to Holochain I was skeptical but in the months since doing more research, talking to the community, and building some basic apps on it I have come to realize it as one of the best designed software systems I have seen in a long time. This is a compilation of my notes as I research Holochain so it is more like my initial thoughts and observations rather than a technical deep dive. I will be covering its values, core components, and similar technologies.IntroductionThe MetaCurrency Project, the organization behind Holochain, was started years ago (...)

Something fun to use so I actually enjoy building applications.Would Elixir scratch my itch? It was a good start. It made it fun to write beautiful code, but I still encountered bugs in production that could have been caught with a better type system.There’s Elm. It’s beautiful. Fun. But only available on the front-end.I played briefly with Go and Rust, but I felt like the type-system and syntax was too unfriendly for me to enjoy using them.Finally, I tried CrystalAt first, I was pretty put-off by Crystal. It looked almost identical to Ruby, so why would I try it?Well eventually I did try it, and I fell in love (...)

Still, to decide whether RoR is a good fit for your project, you need to know what makes this framework different from others. To help you build a deeper understanding of RoR, we are (...)
