Building a Portable, Self-powering, Cloud-Connected IoT demo

Or “How to build a portable self-powered, self-licking ice cream cone.” 😀 Several years ago, I started building what I referred to affectionately as a self-licking ice cream cone: a Renewable Energy (RE) system that powered the same IoT system that monitored it. I’ve given several talks about this system, both its hardware and its software stack, and there are so many useful (and scalable) lessons I’ve learned that I really enjoy sharing. ...

T4SD (Tips 4 Spring Devs): Exposing Query Methods in Spring Data REST

But did you know that it provides a no-lifting-required mechanism for exposing query methods you define on those repositories as well? Let’s say you create a method like this: Referencing that bit of functionality directly is simple, just append /search/<methodName> to the collection endpoint: ...

However, if you’re a full-stack developer, by choice or necessity, you need to know this! Grab a chair and a cup of coffee; I think you’ll find this interesting (and useful). ...
