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.
Dear Sir Paul, Re: Royal Society Code of Conduct I am sure that many scientists have written to you about the specific question of Elon Musk’s Fellowship and whether, under the Royal Society’s Code of Conduct, his retaining that Fellowship is appropriate. I will not rehash these issues. Instead, as a female scientist with extensive experience of activities aiming to increase equality, diversity and inclusion in the engineering and physical sciences sector, I am writing to you (in a personal capacity) to ask you to reconsider the statements you have recently made in this context to the UK press about the Royal Society’s Code of Conduct and how it is applied. A 2018 report from the joint National Academies of the United States of America, concluded that “sexual harassment is common in academic science, engineering, and medicine” and that “greater than 50 percent of women faculty and staff and 20–50 percent of women students encounter or experience sexually harassing conduct in academia”. This report described codes of conduct that make clear that sexual harassment is unethical and will not be tolerated as a “powerful incentive for change”. The authors also noted that sexual harassment can have significant and damaging effects on the integrity of research. In my own praxis, I have found that clear and consistently-implemented codes of conduct that address these issues make female scientists and engineers safer, and allow them to focus more effectively on their research. For codes of conduct to have such a positive effect, it is vital that sanctions for actions which transgress the code are meaningful and substantial. I was hence aghast to realise that in an interview with the Financial Times published on 9/1/26, you appear to have suggested that the Royal Society “should only expel fellows if their science proved “faulty or fraudulent or highly defective””. Moreover, in a further interview with the Guardian on 11/1/26 you suggested that the code “may need to be looked at again”, with the implication that your aim would be to remove the option of sanctions on Fellows for reasons not strictly related to faults or defects in their research. I suggest that changing the Royal Society’s code of conduct so that the likelihood of serious sanctions for sexual harassment is reduced, would directly endanger women who interact with the Royal Society at events or otherwise, and would provide a licence to harass to the already powerful people on whom the Society bestows fellowship. The implications of your words - that under your leadership the only infringements of the code which are likely to receive the sanction of the Fellowship being removed are those related to research misconduct - already risk empowering harassers. You stated, in the Financial Times interview, that “there’s many bad people around, but they have made scientific advances”. Given this awareness of the possibility of bad actors in our scientific community, it is wholly irresponsible to suggest that the Royal Society would not act to sanction these people if they harass more vulnerable scientists. I am hence writing to request that you retract any suggestion that the Society’s Code of Conduct should be changed so that the only reason a Fellow might be sanctioned by the removal of their Fellowship is “faulty or fraudulent or highly defective” research. This action is necessary to safeguard female scientists, a requirement placed on the Society by safeguarding legislation and UK statutory guidance. Yours sincerely, Professor Rachel A. Oliver.

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.

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.

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!
