OrlandoJUG Reading List ::: from JavaSpecialists

Issue 275 - EnhancedStream with Dynamic Proxy

In our previous newsletter we enhanced Java 8 Streams by decorating them with an EnhancedStream class. The code had a lot of repetition, which often leads to bugs if written by hand. In this newsletter we use a dynamic proxy to create an EnhancedStream. The resulting code is shorter and more consistent.

Issue 274 - EnhancedStream

Java 8 Streams have a rather narrow-minded view of what makes objects distinct. In this newsletter, we enhance Streams to allow a more flexible approach for deciding uniqueness.

Issue 273 - Truly Public Methods

Class.getMethods() returns all the public methods in this class and the classes in its ancestry. However, we cannot necessarily call these methods, for example if they are declared in a private inner class or a lambda. In this newsletter we attempt to find all truly public methods.

Issue 272 - Hacking Enums Revisited

In a previous newsletter, we looked at how we could dynamically add new enums and also rewire affected switch statements. Due to improvements in Java security, our old approach needs to be updated for Java 12.

Issue 271 - HttpClient Executors

Java 11 added the HttpClient to give us a better way to send HTTP requests. It supports asynchronous and synchronous mode. HTTP2 comes out of the box. The threading is a bit funky though and Professor Cay Horstmann explores how things work underneath the covers.

Live Recorder: Debugging C++, Rust, and Go with Capture and Replay of Nondeterministic Data

Early in the year the Undo team released Live Recorder 5, a “software flight recorder technology” for C, C++ and Go applications that enables the capture of all non-deterministic data within an application’s execution for debugging purposes. The resulting recording supports the replay of events in time, backwards and forwards, when looking for and fixing bugs.

Experiences from Mob Programming at an Insurance Startup

What do you do when two developers in your team mention that they have been stuck on a task for three days? At an insurance startup, the whole team decided to try-out mob programming. From the first day they started to mob, their knowledge of the codebase increased. Working together also helped them to get to know each other better and to be more efficient as a team.
