Downloading the Internet Can you remember the last time you started out on a clean development environment and ran the build of some software using Maven or Gradle for dependency management? It takes ages to download all of the necessary third party libraries from one or more remote repositories, leading to expression like, "Just waiting for Maven to download the Internet". Once your development environment has been used for building a few projects the range of dependencies that will need to be downloaded for other builds reduces down as the previously referenced onces will now be cached and found locally on your computer's hard drive. What happens on the Continuous Integration environment? Now consider what goes on when Jenkins or your other preferred Continuous Integration server comes to build your software. If it doesn't have a local copy of the libraries that have been referenced then it is going to pay the cost of that slow " download the Internet" p...
Just a look back over the last 12 months. January I moved back to Christchurch to live, after having spent a few months further south since moving back from London. Work was mainly around balancing other peoples' understanding and expectations around our use of Kafka. February I decided that it would be worthwhile to have a year's subscription for streaming Sky Sports, as some rugby matches that I would want to watch would be on at time when venues wouldn't be open. Having moved to Christchurch to be close to an office, now found myself working from home as Covid restrictions came back into effect across New Zealand. March Got back into some actual coding at work - as opposed to mainly reviewing pull requests for configuration changes for Kafka topics. This became urgent, as the command line interface tool that our provisioning system was dependent on had been marked for deprecation. April Had my first direct experience with Covid-19. I only went for a test because ...
Introduction I've been catching up on some features that have been added in recent versions of Java. The 6 month release cadence of new versions of Java is great, but can lead to a build up of new things to learn about. The support for pattern matching in switch statements - JEP 406 - is particularly appealing, but for now it is still only available as a preview feature, meaning that at compile time and at run time we need to explicitly specify to enable preview. A shallow view of the main cloud providers A lot of online applications these days will run in some sort of cloud runtime environment. Some examples from the main cloud providers are: AWS Lambda Azure Functions Google Cloud Function According to what the documentation currently specifies, AWS Lambda's pre-packaged Java environments only support versions 8 and 11 unless you bring your own Docker container. Similarly, Azure Functions only offer versions 8 and 11. This leaves us to consider Google Cloud Functi...
