Wow, sure would be pretty crazy if a ton of experts in the artificial intelligence field relentlessly warned everyone about this state of affairs being inevitable over and over for years.

Conservatively estimated 32 millon hectares of land is used for producing 1,400 TWh of biofuel per year. If that land instead was covered* by solar panels, it would surpass the *total* current electricity production worldwide 🤯.

*: Not that it should, just for comparison.

Following coverage over the weekend of Sir Paul Nurse's comments that suggested that the only reason that a Fellow should be expelled from @royalsociety.org is scientific misconduct, I have written to him to explain the risks such an attitude poses of increasing sexual harassment in STEM.

Nur mündliche und schriftliche Prüfungen in Person sind einigermaßen KI sicher. Finde diese Prüfungsform zwar pädagogisch nicht toll. Hatte eigentlich bei dem Modul das ich übernommen habe vor die Prüfungsform zu aktualisieren. Werde das aber jetzt lassen und bei der schriftlichen Prüfung bleiben.

Intriguing theory! What about olive oil?

A German court has held X AI liable for false claims made by grok about the NGO Campact. In contrast to other LLMs, grok posts publicly and does not only show answers to one user. This made a big difference in this case, wonder if it will play a role here.

The audience at #39C3 was stunned and actually in disbelief. Saw many listeners check on their phones if the white supremacist site WhiteDate was really offline (it was).

This was impressive to witness in person. The room was packed, the talk was interesting combining the insights the hacker had gained from infiltrating the site and the extra research the journalists had carried out. In the last few minutes: Surprise! The websites, and accounts are gone!

Bei meinem letzten (internationalen) Umzug riefen sie morgen am Tag vor dem vereinbarten Termin an um mir mitzuteilen sie würden jetzt doch schon einen Tag früher am Nachmittag kommen. Ich war noch am packen in der Küche als der Fahrer eintraf.

What is the citation for this? How does it relate to measuring sea levels?

This is meaningless. Today New York Upper Bay had a 6ft difference between high and low tide. To compare anything visually you would need to exclude the effect of the tides. Which is impossible in a photo. This is why the actual decades of data are much more useful to measure long-term changes.

Then you should share your source which hopefully has the calculations that were being asked for.
What harms do wind and solar do (compared to a lignite coal powered plant)?

Close to Freiburg in the Black Forest. We started from S-Bahn stop Hinterzarten.

Here, have a couple more pictures of the winter wonderland that the Black Forest currently is.

Danke dass du es nicht ignoriert hast.

I love winter hikes!
Went up to 1000m for today's delightful hike. It was a great hike with amazing company, beautiful landscapes, and heaps of snow.

I am aware of that.
I can still dislike it and point it out.

I hesitate to believe it, just based on a post by Trump. Am sure there will be other sources soon to confirm or deny this. Odd that such information comes out via social media statements instead of official press conference or government statements.

Auch Kurt ist im neuen Jahr angekommen. Das Jahr 1916 geht für ihn an der Westfront ruhig los und das Projekt Kurts1662Tage läuft weiter. Immer genau 110 Jahre nachdem sie geschrieben wurden sind die Tagebucheinträge online auf Kurts1662Tage.de. Schau mal rein!

Schau dir mal @polyluxnetwork.bsky.social an. Die unterstützen viele tolle Gruppen.
