Today was a fun day. It had been a while doing CTF's. So I am not an expert but enjoyed doing it. The #SURFcert put in a lot of effort to make it nice. So kudos to the organization. Hopefully I can join next year again 😄 #surfcert #ctf #ct
Going to Utrecht today for a capture the flag from #SURFcert And travelling by train as it close to the central station. Did check to go by car because of personal reasons. But whoa. Parking is mucho expensive. It would have cost me €31,-.
