Today I have a more serious topic than usual, please consider reposting for reach:
My wife and I are urgently looking for a specialist in neuropediatrics or a similar field for our autistic child with a diagnosed, but not further specified, movement disorder (myoclonus and/or spasms) to finally find a cause and, above all, an effective therapy. The symptoms are bothering our son ever since he’s born, now for more than nine years, seriously affecting his sleep. The usual processes and medical contact points have failed us unfortunately and he seems stuck in this condition.
We’re based in Berlin, Germany but really any contact with a specialist who would be willing to take on this case we’d be grateful for!
To reach use you can DM me or contact us via Email at unclear.condition@gmail.com
Really a huge honor for me to be invited to give a keynote at NULLCON Berlin in September.
Given my recent work focus at GitLab I'll share my thoughts around LLMs. Make sure to bring some popcorn!
If only I could remember where I put that token about 3 1/2 years ago

Cross functional steakholder or something, no clue I don’t eat meat…
Thanks AI
Parser Differentials have become pretty much my favorite bug class over the last years.
I am absolutely honored to get the chance to present on this topic at OffensiveCon in a few weeks.
Felt cute, might delete later
AI being useful
Soooo I built a little website based exploit for some CORS issue. Claude was really helpful to not only spit out a reasonably fast portscanner to use to find the target but also I used it to have a dark/light mode with a toggle and detection of the system default for the site.

Next question:
Since I try to stay off of Twitter and don't post any more content over there please suggest some accounts I should follow here. My timeline needs some more content :D
I got a week of PTO left.
What code should I read? Please drop suggestions with a reason why I should read it.
