@[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/.

@[email protected]100% artisanal, human-made bytes.
Anti-DEI is white supremacy. Black lives matter. LGBT+ rights are human rights. Healthcare, security, a decent income, and housing with dignity are human rights. Abortion is healthcare. Science is our best hope. Kindness and empathy are the noblest of human traits.
It can ALWAYS get worse.
He/him.

I once worked with goats. I moved into tech.This was a mistake.
Expect sheep, wool, and textile history. Also birbs. Infosec on occasion.
I use content warnings for topics and images that can trigger PTSD. I do not use them to shield people ***without*** trauma from experiencing racism, sexism, transphobia, and other forms of discrimination. If you can ignore politics, you’re not likely in need of content warnings for much of anything, really.

Huge SciFi fan 🖖
Just a cold robot on the internet hacking, shitposting, helping and doing things
I joke. A lot.
I post about planes and ATC stuff. A lot.
Pretty unfiltered, thoughts/opinions my own not my employers. Probably overanalyzing things... Or am I? What does that really mean? Maybe if I calculate the optimal amount of analysis...
