• Java with a Clojure mindset

  Oredev 2018, Java2Days 2018 November 23, 2018

  New languages bring new ways of thinking and teach us new principles and tools that we can bring back to your day to day language.

  Using a real application as an example, we will learn how to build and design Java applications that follow Clojure’s functional principles using just core Java, without any libraries, lambdas, streams or weird syntax; and we will see what benefits those functional principles can bring.

• Habits of Efficient Developers

  WeAreDevelopers 2018, GeeCon Prague 2019, GOTO Oslo 2020 June 14, 2018

  Even if a 10x developer may be a myth, we all know of some developer that just shines and is able to do more in less time, and seems to do it without effort! Even if may seem that you need some kind of special natural talent, it is not.

  In this session to learn what you need to learn to become a more efficient developer.

• All things data

  JaxLondon 2017 October 11, 2017

  In essence, any program only does one thing: move data from one place to another, usually transforming the data on its way.

  But even if data is data, we tend to hide it in layers and layers of specific APIs and specialized types, where we lose the benefits of one single and unified API.

  As Alan Perlis said: "It is better to have 100 functions operate on one data structure than 10 functions on 10 data structures."

  In this session we will see how if we represent every thing…

  As Alan Perlis said: "It is better to have 100 functions operate on one data structure than 10 functions on 10 data structures."

  In this session we will see how if we represent every thing as simple data, from our DBs to the UIs, our programs can become simpler, our abstractions more generic and our code more reusable.

• Applying stability patterns: a case study

  Devoxx PL 2017 / JBCN conf 2017 August 1, 2017

  We all know how painful is to be paged at 3 am because the site is not responding.

  Netflix has made popular the Circuit Breaker pattern, but that is just one of the stability patterns of Michael Nygard's "Release it!" book.

  On this presentation, you will learn each of the stability patterns found in the "Release it!" book and we will look at practical examples of how they were applied while building a Java based system that integrates and mash up information from more than twenty…

  On this presentation, you will learn each of the stability patterns found in the "Release it!" book and we will look at practical examples of how they were applied while building a Java based system that integrates and mash up information from more than twenty different sources, some of them quite unreliable.

• Repl Driven Development

  Voxxed Days Belgrade 2016 / JDD 2016 / GeeCon 2018 October 21, 2016

  Drinking too much coffee while maven builds and deploys your service?
  Jealous of how your FrontEnd mate just press F5 to 'deploy' his/her changes?
  Mastered the red-green-refactor workflow and want to know what is the next step?

  Our Lisp grandfathers knew how invaluable was the immediate feedback that a Read-Eval-Print Loop (REPL) allowed during development and now Java 9 will have one. Perhaps you have read that a REPL is useful for 'playing around' or for 'small code snippets',…

  Drinking too much coffee while maven builds and deploys your service?
  Jealous of how your FrontEnd mate just press F5 to 'deploy' his/her changes?
  Mastered the red-green-refactor workflow and want to know what is the next step?

  Our Lisp grandfathers knew how invaluable was the immediate feedback that a Read-Eval-Print Loop (REPL) allowed during development and now Java 9 will have one. Perhaps you have read that a REPL is useful for 'playing around' or for 'small code snippets', but this is far from true.

  In this presentation, you will learn how with a REPL you can have a better and more productive developer workflow by building a Tomcat service, one bit at a time, without having to build, compile, package or deploy it.

  Demo will be done with a Clojure REPL but no previous experience with Clojure is needed.
