Wir verlassen X. In Hamburg sagt man Tschüss (zu Fake News, Hetze, Diskriminierung, Hatespeech & Verherrlichung von Gewalt). Der mit Musks Übernahme von Twitter eingeleitete Niedergang hat zuletzt einen nicht mehr zu tolerierenden Tiefpunkt erreicht: blog.sub.uni-hamburg.de?p=39327 #eXit

Tested 3D printing some lattice structures (just Graphene for now), and it works really quite well! Now I want to print another large Graphene sheet to visualise twisted Bilayer Graphene and create models of some lattices myself.

Huge win from @franzanth.bsky.social creating a Content Scraper Blocklist: bsky.app/profile/cont...

It's a blocklist for the kinds of engagement bait accounts that repost stolen content, often with misleading captions.

And back to Hamburg, reading The Fifth Season by N.K. Jemisin. Will take the afternoon to analyse the results of some compute jobs from the weekend, easing into the week a bit.

When I was a student employee at my university’s data centre I also got the tour of the server rooms and the tape backups (plural, because we need them at multiple places). Was so fascinating to see.

(Also thank you for that tip, that would make great gifts for some of my HEP friends)
Interesting fact: at @cern.bsky.social we still back up data (Exobytes = million terabytes) on tape because it is more reliable than hard drives. They also last longer, are cheaper and much more environmentally friendly

You can buy old tapes as souvenirs🤩 📼

Hello #sciky, I spent today with my parents baking a variety of cookies and used the break to set up my profile here and follow some people. Tomorrow: back to the institute to continue working on my master's project.
