Finally managed to sit down this weekend and finish #flareon12. The last one was a bit of a struggle and I made a lot of mistakes but got there in the end. Thanks a lot Nick Harbour and team for another successful edition. Looking forward to write-ups.

After 1400 days I'm dropping my German Duolingo streak. It definitely helped me with the basics while I lived in Switzerland but that motivation is now gone. On to learning other things instead.

Thanks a lot to @nickharbour and team for this year's #FlareOn11. Solid challenges overall. I especially enjoyed 5, 7 & 9. Looking forward to seeing solutions for 9. I feel like there are multiple things I could have done better but overall I learned a lot this year.

This year I've organised more #CTF than I've played but I got in the mood this weekend and played snakeCTF with @royal_roppers. We managed to secure first place and a finals spot! Thanks to MadrHacks for hosting.

APB: I seem to have lost my Dr. Carol pin somewhere on the DEFCON floor. If you find it I would be immensely grateful to have it back. :)

A friend built a computer but didn't have a case. Luckily, the motherboard came with one.

Quite the mix of genres as usual. Also kind of feels great with both new discoveries (Dance with the Dead is def my find of the year) with old favourites (kent is still sorely missed).

I was off to a slow start due to all my travel but finally managed to finish #flareon10. Thanks a lot, @nickharbour and team for some great challenges!
The last few were really cool!

For the past few years I've been using a great fiverr artist to create some artwork for work. Unfortunately they have been MIA for 2+ months now and I realise that I probably need redundancy. I'm looking for a cartoon artist with similar style.

I had a blast hosting @livectf together with our great team. Sure it was a bit stressful and an emotional rollercoaster but the reactions have been positive. I might write more later but for now I'll settle for posting this masterpiece by the genius @zaratec4

Proud moment. My, to my knowledge, first #chess move rated "brilliant" by @chesscom game was a draw in the end. I went low on time and had to repeat positions instead of pushing for a win. Still happy though. :D

I played the @1ns0mn1h4ck #CTF together with @TeamTasteless in Lausanne. We managed to get a 6th place and beat most of the other boomer teams so I'm pretty happy. Thanks for having me as a guest player and thanks for a great event! :D

It's not only Spotify that does the yearly review thing now. While I definitely have made some progress there's still a long long way to go. #Duolingo365

Did some environmental "hacktivism" yesterday by playing the @EPT_gg Equinor #CTF as team "Blekkulfklubben" together with @0xbadcafe1, @maritio_o and friends and donating our prize money to charity. Thanks for a nice competition!

Ok, thanks to some silly mistakes, this took way longer than it should have but at least I finally finished. Thanks a lot to @nickharbour and the rest of the #FlareOn9 organizers for a nice set of challenges this year as well! Good luck to everyone else playing!
