Ever wondered if applications really have to be written to target servers or containers? Can they be more flexible so that they run anywhere? I recently had to create a Probot application that worked on VMs, containers, and serverless platforms. And I needed to do that without writing multiple versions of the code.

Ever wondered why some numbers never seem to add up? Or why adding 0.1 and 0.2 doesn’t exactly equal 0.3 in JavaScript? Or why adding two numbers sometimes gives an unexpected value with floats and doubles in C# and Java? It’s time to understand floating point numbers and the magic that makes them operate.

Java makes it surprisingly easy to manage and package complex projects using Apache Maven. One question I’m frequently asked – how does this integrate with GitHub Actions? Turns out that the answer is “surprisingly well!”
