Boris Shingarov

Boris began his career as a theoretical physicist at MSU "M.V.Lomonosov". After learning about the existence of Smalltalk in 1994, he has made a number of fundamental contributions to Smalltalk through his work at major Smalltalk companies such as The Object People, IBM/OTI, and Cincom. Boris is the co-author of the IBM VisualAge for Smalltalk Handbook, one of the Founding Committers of Eclipse, and the named inventor on patents relating to a wide range of fields (from code generation and database structures for information retrieval, to music notation for mediæval chant). Boris' current job at LabWare is to invent the Smalltalk of the future as a first-class citizen in the global computational landscape. This entails working on the specifications of RISC-V and OpenPOWER (the two open-source computational platforms) as an embodiment of the Smalltalk paradigm.

Carlos E. Ferro

I am a regular at Smalltalks since the very first one and still did not miss one. Does that say something about my life? I work on Smalltalk since 1999, I discovered it thanks to Máximo Prieto while studying Computer Science at FCEyN, UBA and it changed my life. I have worked as a developer since 1986 using other technologies that I would like not to see again... Besides programming, I was assistant at OOP courses for several years, I wrote a good deal of fiction, I am a hobbyist proofreader and regularly answer questions in Quora. Oh, and I used to read a lot, now I only read a good deal.
