At Spotify, we’re doing more and more Java (Spotify started out as a Python-mostly shop, but performance requirements are changing that), and we’re doing more and more complex, asynchronous Java stuff. By ‘complex, asynchronous’, I mean things along the veins of:. Call a search engine for a list of albums matching a certain query string. The pattern of using Futures....

It's all about the Coding. Petter Måhlén's Blog. Fluent APIs in Java. Posted by Petter Måhlén. On January 15, 2013. In our inventory management system at Shopzilla we’ve got a reporting tool that we’ve built using Wicket. A couple of months ago (this post has languished in draft status for a while), I was going to add a new page and took a look at a previous one to see what I could copy/paste. What I found was this wall of text for creating a table:. There’s also missing information: as an example,...
