Music Act: Hacker Music Quiz

WE love music, at least I do, but I know a lot of hackers love music!

So why not do a music quiz! Themed with the music you should know if you are a hacker type! We will also do various other themes for everyone. The plan is, I will be at the controls and play music. About 30 second clips, maybe more and you will guess!

The guessing will be on a shared Signal group, and no prices awarded - just pure bragging rights if you get it right.

The categories are not fixed yet, b… Read more

Kubernetes is everywhere and can support many interesting use-cases for hosting services.

This talk is based on my experience as a Unix, Internet and Security person with researching K8s over some years and setting up my own infrastructure with Kubernetes in a small production setup. The main points in the talk are:

  • Why would you run K8s on-premise, being appropriately paranoid and a control freak

  • How do you bring up a bare-metal test-cluster using K… Read more

A small workshop teaching people how to produce DDoS simulation traffic - useful for testing their own infrastructures. We will have a server connected on 10Gbps on a switch with multiple 1Gbps port for attackers. Attackers can be connected through 1Gbps ports using USB Ethernet - we have loaners.

Work together to produce as much attack traffic while having fun.

WHILE attack is ongoing there will be ample opportunities to monitor traffic, monitor port, and decide on changes to … Read more
