DEF CON
@[email protected]DEF CON is the world's most influential hacker conference. Held every year since 1993 in Las Vegas, Nevada, DEF CON is the hub of a global community of hackers, security geeks and curious technophiles.
World Wide Web Consortium
@[email protected]The World Wide Web Consortium (W3C) was established in 1994 by Web inventor Tim Berners-Lee, to develop interoperable standards to lead the Web to its full potential.
We are an international multi-stakeholder community where member organizations, a full-time staff, and the public work together to build a Web based on the principles of accessibility, internationalization, privacy and security.
Please be more curious than critical. Your interactions go to real people who care and do their best 🙏

@[email protected]I do #cloudsecurity and #blog on a dopamine dictated schedule. I'm #queer and enjoy #coffee. I try to self-host as much as I can because I don't like being someone's product. My opinions are my own and not that of my current or former employers. I hang out in hacker spaces, go to hacker conferences, and create my own shitty mspaint art for my blogs. I immigrated from Seattle to the Netherlands with my primary partner.

My friends call me Bubba.
WARY of AI images and vibe coding, tho I do ALL of those. Believe AI gen Apps need a deep security audit BEFORE RELEASE, but that won’t happen.

@[email protected]Working at front lines of the IT and having fun there. Been around the Internet since 1992 and still in awe what has become of that little baby.
Personal interests:
- IT Security
- Computer Games & TTRPGs
- Cycling
- Cooking & Baking
- Books, Movies, TV-Series (mostly F&SF)
- Everything that blinks, has buttons to press and looks remotely gadgetoid
Everything i write, post, tweet, blog or blurp is just my personal opinion and is not the opinion or policy of my employer, my cat or my goldfish.
I post in English and German. Will try to mark each post correctly, but errors happen. Sorry for that.
I appologize if I am not following you back. This happens as my stream is already getting more posts than I can read.
