Today we are going to play Potato Pirates 2 - Enter the Spudnet at work.
It's a fun board game with a little bit of cyber security mixed in.
It's a test run. I want to play that at the girls day this year. The girls (and boys) day is a special day in Germany, there kids are encouraged to experience jobs, that are biased towards certain gender. For example information technology or child care.
This is the third year my employer participates and offers a broad experience of jobs in computer science. PO, Scrum master, cyber security, developer.
So far we got very positive feedback from the young people and I hope that we can reduce the gatekeeping in these jobs.

If you are a little bit older and want to play that game or learn more about cyber security without previous experience, maybe the @OSCo is something for you.
It's an un-conference in the open space format focused on cyber security. I'm one of the organizers and our goal is to reduce gatekeeping and to create a safe space for everyone, regardless of experience, age, gender, religion, skin colour or disability.
The open security conference 2026 is scheduled for 5-8 November 2026 in the SeminarZentrum Rückersbach (Germany):

Open Security Conference
New year, new #osco! ✨ We're about to regroup and get things started for #osco26, the third edition of the Open Security Conference taking place on November 5-8. We're also super happy to welcome new organizing team members! 🤩 Stay tuned. 😉 #CyberSecurity #Security #InfoSec #AppSec [lisi]

The year 2025 is slowly coming to an end.

End of years can be joyful and relaxing, exciting and wholesome, full of reflection and gaining energy for the new year. This time can also be lonely and sad, incredibly stressful and terribly difficult to navigate, with folks barely making it through.

Let's be mindful and considerate - and help each other to move the needle. Now and in 2026. 💜
