JSON object mapping, marshalling, call it whatever you want, we have you covered with Gson or Jackson. Unless you don’t care about structure and want to be able to parse random JSON strings. Oops, THERE come clumsiness.Continue reading
IT must be easy, oh yeah. After years of courses and university and everything else, just because they were put together by the brightest educational minds you should be able in a second to program this new web application, integrate external web services, add a new GUI and adapt your friend’s broken Excel import, all while cleaning up grandma’s computer for the hundredth time. Even kids are to be taught programming, so it can’t be much in it right? How MANY times I heard this told in various ways “it can’t be so difficult”… Everybody has challenging jobs but as soon these involve computers everything should become a breeze, somehow. When did we get into this???
But I digress. So, first a bit of context: I thought it would be big time I followed my own thinking from a month ago (see “Proof of concept, with a concept”) and actually migrate the proof of concept code from “Ractive.js and vert.x integration over the event bus” to use Elasticsearch.

One problem I have when trying new technologies is actually seeing them in realistic situations – which translates to having a real use case for them. Think about this: when you build a “hello world” application you actually couldn’t be further away from the real world! I guess that’s why nobody calls it “hello real world” anyway… The whole experience you get from the proof of concept is just random installation trivia if you’re not using it to prove a point. That’s why it’s called “proof of concept” – it should have a concept, silly. Continue reading
When I first combined the Internet and programming it was the second half of the 90’s and all I knew was Java applets. Oh, there was also CGI but I somehow managed to skip over it. The approach was then quite natural: write small programs which will run in the browser and grab data from other programs – run in either other browsers or on the server. Or on other servers. I’m not saying the idea was easy and I only got that far before I moved on to other professional areas. Later when I came back to the web, things had settled differently: you had a servlet specification, a multitiered application to support them, big servers and everything was clear. Of course there was some bit of fight over technologies, gradual improvements here and there but the model was there already. Continue reading
