So I’ve been playing around with Go a lot, trying to show that I am one of the cool cloud and container kids, y’know. Go is what all the cool cloud and container kids use these days. Anyway, Go is a typed language, which means you have to declare your variables in the form var foo int with the type coming after the variable name (unlike C and similar, where you have the type before the variable name).

Greetings from the HPC Support trenches! Here’s your standard issue ssh credentials to various clusters, your How To Interact With Users Without Strangling Them Handbook, and your radio should you need to call for backup from the admin mages.

Life can truly be comically tragic sometimes. I experienced that this past week and thought I should write about it, share with you this rollercoaster adventure (not really, I’m just being dramatic). Before we go on, we must first introduce the subject of our sad tale.

Now that I’m officially part of the DSSL at Virginia Tech (Hey! I’m in the Slack group. That’s totes official), I’ve got access to their servers to work on projects and stuff. I’m working with one of the PhD students in the lab on a project involving prefetching Docker layers from a registry and caching Docker layers to serve them faster, but also involves choosing the right layers to prefetch to maximize cache hits.
