There are many different ways to teach topics of software developments. From recorded lectures to pair programming. Over the time we tried many of them with different customers and different topics. I want to provide you with an overview of what worked best for us for which topic.

While it can make a lot of sense to use a dedicated service for a well defined problem those services are sometimes used just to play with a different server software. While it is pretty obvious for most that selecting the right database is important the same is true for selecting the right language (virtual machine) for the job.There are different types of services or server applications where different types of virtual machines (executing the opcodes / bytecode of the compiled source code) make more or less sense. What are the criteria we should base such a decision on and which language should we choose when?

After all the underlying Lucene index engine provides far more powerful features then a plain MySQL full text search or similar solutions. With Apache Solr and ElasticSearch you can enhance the performance and the functionality of your website. What we often stumble across, though, is the naiive approach of synchronizing both data storages which tends to fail in multiple ways. Let me show how you can fix this.

Refactoring is an essential part of everyday programming and should become knee-jerk for your whole development team. It is very helpful to cleanup feature spikes, revise earlier decisions and keep a maintainable code base in the long run. In a perfect project world - with extensive automated tests of various types - this is just a matter of getting used to. But there are only very few such projects, so getting into proper refactoring is much harder. This article will show you important tips to master this challenge with your team.

This is either because of scaling requirements or because developers like to try out new technologies like implementing Microservices. What are the challenges with this and how can we overcome them?
