Interesting open source projects to look at

/ nidkil / Leave a comment

This will be a never ending list of open source projects I want to look into. They look like potential candidates to be used on future projects, but need more thorough analysis.

  • Kamon – Reactive Application Monitoring: Kamon is a Open Source set of tools that help you to get metrics out of your reactive applications built on top of Akka, Spray and Play! Kamon uses bytecode instrumentation to introduce metrics and tracing logic into your application, without you having to modify a single line of code. All the collected information is available through a simple, actor-based messaging protocol with integrations already available out of the box.

Any suggestions you think I should look into?

ClassNotFoundException when adding slf4j to Akka

When adding to a Akka project I got the following error java.lang.ClassNotFoundException: akka.event.slf4j.Slf4jLogger. I double checked my configuration and the Akka documentation. The documentation says the following:

Akka provides a logger for SL4FJ. This module is available in the ‘akka-slf4j.jar’. It has one single dependency; the slf4j-api jar. In runtime you also need a SLF4J backend, we recommend Logback.

No success. Continue reading →

When printing the config to the terminal it is displayed in a compact format. I wanted to pretty print it so it was easier to read. I found a briljant blog post by marcinkubala.

I adapted a code snippet as follows: Continue reading →

Deleting a remote tag in Git

/ nidkil / Leave a comment

Today I deleted a tag in Eclipse using EGit that was already pushed to the origin. I then discovered that once the tag is deleted in the local repository there is no way in EGit to delete it from the origin. I am using Github as remote repository. So I checked if the tag could be deleted there. Unfortunately I could not find a delete option there. Bummer what now? Command line git to the rescue. Continue reading →
