“A lot of our privacy … rests on tech companies saying ‘no’ ... when the government comes with an illegal order,” EFF’s Cindy Cohn told @mercurynews.com. If they don’t, “it can really empower the government to do a lot of surveillance and a lot of repression.”

Having taken a look at Ashes of Creation again, I remembered the cosplayer I met at Japan Expo some years ago.. such a nice cosplay! I sadly do not know who the cosplayer is, as they would not speak (I asked them then)

Hi Bluesky 🦋
I’m a Masters student at DIKU, UCPH. I’m especially interested in computer systems (architecture, embedded, distributed), High Performance Computing and Computer Security as topics, and I’m currently learning more about how SSDs work, as well as the architecture of RISC-V.
Let’s chat!

The House is about to vote on a bill that would give broad and easily abused new powers to the executive branch to allow the Secretary of Treasury to strip a U.S. nonprofit of its tax-exempt status. Tell Congress to vote NO on H.R. 9495.

Just finished watching "What's Really Happening At CERN" by Cleo Abram and her team, and I've immediately fallen in love with the video style. The fact that she links to actual experts and other explainers is magnificent.
