Here's what happened at Hackoween πŸŽƒ

Β· 3 min read

Just as October was about to close, we ran a hackathon, aptly named "Hackoween" πŸŽƒ

Hackdays are a great way for everyone in the company to work together in creating new innovative solutions for everyday problems.


This time, we had the joy of having a hackday that included 15+ teams and yes - pizza. As with anything these days, a hackathon is a mix of virtual and physical.

Hackday Presentations

Building a system overview for wgtwo​

Team: Karl Johan, Anders, Tor, Oliver, Tobias

Building a new "Telco 102" visualization of our system architecture - used for both internal onboarding and to aid us when we talk to customers.

Side-project to see what we could get out of our Java/Kotlin services by utilizing existing projects. Utilize the setup the Infrastructure team has made in dev around opentelemetry and XRay. The idea is to improve tracing across the stack.

Gophish - for internal anti-phishing campaign​

Handover Machine 2000 (Hammer2000)​

Team: Holger, Sindre, Rune, Alain, Jacob

For testing handover between two physical antennas a phone needs to move between the coverage of two antennas. This has historically been done by moving a human holding a phone between two antennas. We attenuenated the radio signal with a rotating BLANDA BLANK serving bowl from Ikea - remotely controlled, of course!

In a bright future, we want a physical contraption that will move a phone between the coverage areas of the antennas.
