The Eclipse IoT Working Group launched the 2019 IoT Developer Survey earlier on in February. This is an annual survey that delivers valuable insight into programing languages, platforms and infrastructure for building IoT solutions. As always the results are shared with everyone. You can find the insights and key findings from previous years posted over here: 2018, 2017 and 2016.
So please, if you are an IoT developer we want to hear from you! Responses will be collected until March 8th.
