Java: The No. 1 Platform For IoT Development

There were two interesting pieces of news this week related to the use of Java in embedded devices to help power the so-called “Internet of Things” (IoT). The first is the results of a survey carried out by the Eclipse Foundation, (there’s also a slide deck) asking IoT developers about what they’re doing and what

I also highlighted the problem that can arise when exceptions can be thrown from within a Lambda expression used

Unlike some conferences, Jfokus has a “two year rule,” which means that you can present in two consecutive years, but not for a third. As such, I think I have been to most of the ten conferences, but not
