Queues and topics are standard communication channels in messaging systems.
How to use then in AWS, for example to implement the Competing Consumers pattern?
TypeScript application wants tests to be written in TypeScript as well, right?
There is a great library to achive this: jasmine-ts
But how to debug such tests within your IntelliJ IDE?
The library for boundary I/O streams brought the possibility to work with multiple stream written in a single stream.
But what if the stream continues further without containing any more sub-stream? In this case we can use the new released Stop Boundary Stream feature from the same library to ignore the rest of the stream after a boundary was reached.
It's nice to watch a process execution and kill frozen processes after timeout, but when a process is supplying data is not frozen even when it takes a long time.
Release 1.1.0 introduces a new process wrapper to send a heartbeat to reset the timeout explicitly or automatically with every read byte.
New Java library for working with boundary I/O streams was released.
This library provides classes for processing multiple streams withing a single stream bounded by a specific boundary content.

It's a good idea to work with external processes to prevent the system from failure especially when the process is very resources-demanding.
But what if something goes wrong?
Let the watch dog out!
Simple JSON database based on the file-access and server-client approach with the non-blocking server and the reactive (asynchronous non-blocking) client.
It's easy to generate test mock JSON data for a small HTTP request or a similar use, because there is a planty of online tools providing this functionality for you.
But what if you want to generate data for a database performance test for systems like MongoDB or Elasticsearch?
Maybe you are updating your Oracle Professional Certification from Java 7 to Java 8 as I just did a few days ago.
