Balbaert Ivo :
Ivo Balbaert is a lecturer in web programming and databases at CVO Antwerpen, a community college in Belgium. He received a PhD in applied physics from the University of Antwerp in 1986. He worked for 20 years in the software industry as a developer and consultant in several companies, and for 10 years as project manager at the University Hospital of Antwerp. From 2000 onwards, he switched to partly teaching and partly developing software (at KHM Mechelen, CVO Antwerpen). He also wrote an introductory book in Dutch about developing in Ruby and Rails, Programmeren met Ruby en Rails, published by Van Duuren Media. In 2012, he authored a book on the Go programming language, The Way to Go, published by iUniverse. He has written a number of introductory books for new programming languages, notably Dart, Julia, Rust, and Red, all published by Packt.
