We have just published a bunch of new papers on our Learn page. The first one, Towards Usable Projectional Editors discusses how MPS has improved the usability of the projectional editor over the last few years. The second one, Automated Domain-Specific C Verification with mbeddr is the definitive paper on integrating C-level verification tools into mbeddr in a user-friendly way. Finally, Preliminary Experience of using mbeddr for Developing Embedded Software discusses our experience so far with using mbeddr to develop real systems.
