Pairing Patterns

software-development-2-logo

Pair programming is hard. When most developers start pairing it feels unnatural. After a lifetime of coding alone, headphones on, no human contact; suddenly talking about every damned line of code can seem weird. Counter-productive, even. And yet… effective pairing is the cheapest way to improve code quality. Despite what superficially seems like a halving in productivity – after all, your ...

Making use of the open sources of WSO2 ESB

wso2-logo

When implementing services using the WSO2 stack (or any other open source Java framework) you will sooner or later run into a situation that the framework behaviour doesn’t do what you expect it should do. Or you just want to verify the way a product works. I lately had several of these experiences and I got around it to setup ...

JMH: How to setup and run a JMH benchmark

java-logo

Health Warning! This post describes how to setup and run a simple JMH benchmark.  Micro benchmarks are notoriously difficult to get right and even when you do get them right (by using tools such as JMH) they can still be misleading. Just because your code runs in a certain way in an extremely isolated artificial situation does not mean it will run ...

Storing months of historical metrics from Hystrix in Graphite

java-logo

One of the killer-features of Hystrix is a low-latency, data-intensive and beautiful dashboard:                     Even though it’s just a side-effect of what Hystrix is really doing (circuit breakers, thread pools, timeouts, etc.), it tends to be the most impressive feature. In order to make it work you have to include hystrix-metrics-event-stream ...

Maven Tip: All about executable jars An executable jar is an extremely useful artefact when it comes to distributing your code.  It means that, as long as Java is installed on the client machine, on Windows and Mac at least, your users can just double click the jar and program will launch. Alternatively on the command line the program can ...

ReactiveMongo: Work with array

mongodb-logo

I’ve been working with ReactiveMongo during 6 months. It’s pretty nice realisation of MongoDB driver for Scala. I just have one remark – it has not so good documentation as it should be.
