End-Prgorammer Programming with Steve Krouse

EP04: End-Programmer Programming with Steve Krouse of Val Town ​

We need to start with end-programmer programming to achieve end-user programming where users can spin up personalized apps without knowing how to code. With end-programmer programming, software engineers can build folk applications, integrations, and mini-apps to customize their experience interacting with third-party software. ​

In this episode, learn how Steve Krouse created Val Town to help programmers achieve this.

IPVM Community Call

​IPVM, or the InterPlanetary Virtual Machine, aims to be the easiest, fastest, most secure, and open way to run WebAssembly functions anywhere.

Using content-addressed data, public key infrastructure (PKI), and capabilities, IPVM liberates computation from its dependence on pre-negotiated services and paves the way for interoperability.

Learn more about our progress building Homestar, the first implementation of IPVM.

UCAN Community Call

User Controlled Authorization Networks (UCANs) are an extension of the popular JSON Web Token format specifically designed to enable ways of authorizing offline-first apps and distributed systems.

At a high level, UCANs are a way of doing authorization (“what you can do”) where users are fully in control. There’s no all-powerful authorization server or server of any kind required. Everything that a user is allowed to do is captured directly in a key or token and can be sent to anyone who knows how to interpret this format.

Join us as we work towards the release of v1.0.
