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.
René Mayrhofer

@[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/.
