Since 2014 I have a small Mini-ITX case which I use as a NAS. After some upgrades, it currently contains two SSDs, three HDDs, and 16GB RAM. In this article, I will introduce 'elbrus' and give some background and specs on her.

As a freelance developer and part-time blogger, I need to switch JDKs regularly. In the morning, I could be developing a legacy system. And in the evening, I'd b writing an article on a JDK preview feature such as text blocks. And in the night, I'm working on small PR for openHAB. In today's post, I'll share some aliases that I use to easily switch JDK's on my MacBook's.

Last weekend I updated my ZFS NAS from Ubuntu 18.04.5 LTS (Bionic Beaver) to Ubuntu 20.04.1 LTS (Focal Fossa). However, after the update, my HEOS speakers refused to play any music. After some tinkering, I was able to resolve this by re-enabling SMB1 or actually NT1 support.
