had an awesome day at the #BSidesMunich2025 workshops. kudos the the team and presenters for creating an awesome event like this. looking forward to Monday and will be back next year for sure
I scored 15/21 on https://e-mail.wtf and all I got was this lousy text to share on social media.
#osae24 thank you very much to the openSUSE Asia team and volunteers for this awesome experience. I had a wonderful time and great conversations. Arigato!
enjoying sake at #osae24 with my friends @_Y___h and others
We're hiring a security engineer with strong SELinux background: https://jobs.suse.com/us/en/job/71006137/SELinux-Security-Engineer

This works perfectly. Doesn't upload the files, but processes them locally. At least with my files I needed to do no configuration and the result is flawless
anyone else having issues with shodan? All my queries time out, but I don't see people talking about this, so I doubt this is a general issue
Ruhrsec (https://www.ruhrsec.de/2023/) early bird tickets just became available. Great conference in Germany with interesting topics and great discussions. It's smaller than other conferences, which is a benefit in my mind.
