We're feeling hopeful with you. 🌞 [lisi]

That would be beyond awesome! Crossing fingers for all of us. 🤞🏻 [lisi]

Oh no, that's too unfortunate! Totally understandable though, as much as we would love to have you. We're still clarifying dates for 2027, hoping those will fit well 🍀 [lisi]

Huge thanks to everyone for coming and contributing and sharing so much invaluable feedback - this gives more energy than you might realize. Lots of love also for my fellow organizers to make this unique event called #osco happen! My heart is full. ❤️ 2/2

Continued with me giving a super relaxed version of my workshop "Secure Development Lifecycle Applied - How to Make Things a Bit More Secure than Yesterday Every Day". Seems folks had fun practicing together. 🎉 #osco gave just the right space and crowd for it. 2/2

We're so glad to have you all. See you at #osco26! 🤩

Finally, finished the day with playing games and having great conversations. 💜 Very grateful for such a kind human crowd. And based on the feedback received so far, it wasn't only me having a great time at #osco! 🤩 4/4

Had great company at dinner and hence respective conversations. Of course, in the evening I gave another session of "Capture the flag Together" going on exploration into a system, and again many folks were eager to find these hidden secrets. 3/4

Joined really great sessions, on using OSINT for good, on deception, on hacking tools. My co-conspirator Martin Schmidt offered people to playtest our little security card game - lots of fun and invaluable feedback. 2/4

Oh the tension, we're super curious what we'll all learn today! 😁 Yet one thing is for sure - whatever it is, it'll be in the common interest for folks. One of the beauties of an open space. 🌻

The perfect closing for the day: chilling at the bar, trying ourselves at lockpicking. 🔓 So glad I finally had this opportunity!

What an insightful and enjoyable day at #osco. 💜 3/3
