There are generally 6 different accepted levels of logging: FATAL, ERROR, WARN, INFO, DEBUG, and TRACE. I think we can all imagine use cases for ERROR, INFO, and DEBUG, but what about the rest? When is something TRACE and not DEBUG, or WARN instead of ERROR.
When working with Terraform, the state file is one of the most sensitive assets in your infrastructure stack. It doesn't just track resources, it often contains confidential details such as resource IDs, networking configurations, and even secrets or credentials that may have been provisioned. When using an S3 backend, and S3 bucket policy can add additional protection.
It's possible to upgrade Ubuntu to a version that's past its end-of-life (EOL) date. This is useful if you really don't want to do a fresh install.
Enable record aggregation in the AWS Kinesis Firehose Agent daemon and potentially halve your Firehose costs.
In this article we'll go over how to set up multiple environments, such as development and production, in Terraform without duplicating any files.
In this article we'll go over how to set up a drives for encrypted access using Btrfs, dm-crypt, and LUKS. This method is similar to the one used by default in the Ubuntu installer.
Beginner's introduction to CompletableFutures in Java 1.8.
In this post I will outline how to build a jar in Gradle that includes all project dependencies, a so-called "fat jar". However, this implementation will allow you to selectively exclude certain dependencies from the packaged jar. The motivation for this came while using Apache Storm, where any dependencies must be bundled in the jar, but the Storm libraries themselves are provided by the runtime environment and thus must not be bundled.
Resetting a user's password can be a simple thing to do, providing you avoid certain pitfalls.
Old canvas hack that generates trees.
My super simple recipe for Danish meatballs, or "Frikadeller" as they're called in Danish. Nothing special, but someone asked for it, so I'm leaving it here. According to my dad, who gave me the recipe, this batch makes about 12, though I have never counted. Normally in Denmark we'd serve this with a healthy portion of white potatoes and gravy, but you can have it however you like.
Yeah that's right, it works! The only thing I was not able to make work immediately was sound, but I can live without that.
Ages ago I created a script to generate a visual representation of the earth from space. Since then it stopped working, but I'm happy to announce that I've updated the code and it now works again.
One of the problems with using GWT is that when you run in devmode, GWT manages its own instance of a Jetty server (I think it's a Jetty server anyway).

In order to get around this problem, you have to set up a proxy server of some sort.
