Questions from anonymous:
- Java EE status – during my studies, I utilized Java EE 6 for creating distributed system to monitor IT infrastructure. Now is 2016 and situation of Java EE is not in bright colors – Oracle reluctant to invest in Java EE standard, concern expressed in formation of “Java EE Guardians” that you are part of. I learned much from it and gave me ability to think “at scale”, distributed manner. But recent developments around standard, started my evaluation - if Java EE is worth pursuing in long term.
- Java EE Backend Development – I find great joy in creating backend software – RESTful web services in JAX-RS or Restlet, business logic or database integration using ORM (JPA or Hibernate). Not mentioning Big Data “movement” with Apache Hadoop and Spark frameworks. But Java EE offers I was looking up, almost always require Angular or other JS libraries. More and more employers require “Full-stack” engineers. Is simply market for specialized backend engineers is shrinking and should I adapt to it or is it simply reality of software development – backend can be reused and GUI trends (Desktop or Web) change all the time ?
- Java and JavaScript – In my projects, I always used statically typed languages – benefit for compile time checks (C/C++ or Java/C#) is undisputed. What would be your advice for Java engineer in regard to JavaScript ? Unavoidable future or majority of development but not all ?
- Thoughts on Golang ?
