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]
Prof. for networks and security at #JKULinz, formerly leading Android platform security at #Google. This account will mostly carry IT security stuff, occasionally politics and other comedy.
Screeching voice of the minority. I will not cooperate with fascists or nazis - traditional or neo; Austrian, German, US, Russian, or otherwise. I will not help build surveillance and oppression states. Never again.
"I need privacy, not because my actions are questionable, but because your judgement and intentions are."
Statements are only my own opinion, not my employers'.
This is currently my primary infosec account in the #Fediverse. It should be #searchable through https://tootfinder.ch. Previous Twitter posts are available in archival form at https://twitterarchive.mayrhofer.eu.org/.
David Chisnall (*Now with 50% more sarcasm!*)
@[email protected]I am Director of System Architecture at SCI Semiconductor and a Visiting Researcher at the University of Cambridge Computer Laboratory. I remain actively involved in the #CHERI project, where I led the early language / compiler strand of the research, and am the maintainer of the #CHERIoT Platform.
I was on the FreeBSD Core Team for two terms, have been an LLVM developer since 2008, am the author of the GNUstep Objective-C runtime (libobjc2 and associated clang support), and am responsible for libcxxrt and the BSD-licensed device tree compiler.
Opinions expressed by me are not necessarily opinions. In all probability they are random ramblings and should be ignored. Failure to ignore may result in severe boredom and / or confusion. Shake well before opening. Keep refrigerated.
Warning: May contain greater than the recommended daily allowance of sarcasm.
No license, implied or explicit, is granted to use any of my posts for training AI models.

Martin Seeger
@[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. Currently wanted for repeated "Nerd Sniping" on all continents.
Personal interests:
- IT Security
- Computer Games & TTRPGs
- Cycling
- Cooking & Baking
- Books, Movies, TV-Series (mostly F&SF)
- 3D printing (new!)
- 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 apologize if I am not following you back. This happens as my stream is already getting more posts than I can read.
