Urbit is a new computing paradigm that provides complete ownership of your digital world. We envision replacing the "ball of mud of conventional software with an entirely new software stack.

Urbit is a deterministic, transactional operating system and network predicated on a lifecycle function and a simple RISC-like combinator calculus. We are building a world for personal computational sovereignty: decentralized peer-to-peer applications, cryptographic identity, and designed to last forever. But the work isn't done yet, and we are meeting compelling and novel challenges in solid-state computing head-on.

The Urbit Systems Technical Journal publishes articles on the ongoing development of Urbit and on solid-state computing more generally. Like the famous Bell Labs Technical Journal on which it is modeled, the Urbit Systems Technical Journal aims to document the engineering work necessary to realize the vision of computing as sovereign, deterministic, and grounded on solid first principles.

In so doing, we hope that these technical problems come to interest and benefit the broader developer community. Functional (as in programming) engineers are often on the leading edge of software development, and the solutions they undertake have required large-scale innovations in the field of computer science generally.

Urbit is currently engaged in such endeavors, such as the Ares project to increase data storage and execution speed of Urbit's low-level interpreted language Nock. This issue of USTJ showcases advancements in dynamic linking, floating-point calculation, and memory management systems. We welcome submissions from those engaged in making computing more solid-state.

Urbit's network is already fully operational and free to use and build on. Scan the QR code below to boot up your own and give it a spin.
