Dev Pulse 113: Big HDK Change

This week’s Holochain release brings a substantial change to the HDK: validation is based on DHT ops, not source chain elements. This change is coming now as part of the core dev team’s effort to stabilise the HDK so you don’t have to refactor your code as often.

Read on for all the news!

Meta-currency: a step towards the Rheonomy

Eric Harris-Braun our Co-founder, suggests that many of our problems are caused by the way the #economy works and to get out of this mess, we need to create new social patterns to replace the broken patterns that aren’t working for us.

Our Co-founder Eric Harris-Braun writes that part of the solution to humanity’s problems is to “build a software toolkit that lets people create, try, and evolve new social patterns.”

Dev Pulse 114 : Big Performance Boosts

Last week’s Holochain release brings improvements on many performance fronts. It tackles some database query inefficiencies, bringing some welcome reductions in RAM and CPU usage. Meanwhile, the developer community is exploring last the previous release’s breaking changes to validation, and have produced some materials worth watching if you’re trying to understand what these changes mean for your hApp.

Highlights:

* More thoughts on breaking changes, commitment to be more explicit about them
* Release notes for .128 (tl;dr: it goes faster)
* Release notes for .129 (maintenance work)
* Documentation work
* Updated tools
- Launcher
- holochain-runner
- Electron template
* Attestations lib
* Threaded comments lib
* Paul's thoughts on the dev community, Ivan Illich, and Tools for conviviality
