Good reminder that there are some amazingly big and complex Earth science missions in orbit. They should get more public attention (in my opinion).

The teams at ESA mission control will now spend around 10 hours carefully unfolding Copernicus's Sentinel-1D’s 12 m radar and two 10 m solar wings. The satellite’s unique deployment sequence was designed to ensure that these complex structures all deploy in the safest possible way.

Germany Blocks EU Chat Control Proposal, Noting That Mass Surveillance Of Encrypted Messages Must Not Be Allowed
Just days after we wrote about the EU's renewed push for chat control, Germany has delivered a very important "no" vote. During discussions with EU countries last Wednesday, Germany's opposition was decisive enough to kill the proposal's momentum and remove it from this week's agenda for EU justice ministers. But it wasn't just a procedural objection—Germany's Justice Minister Stefanie Hubig delivered a statement that drew a very clear and very important line regarding encryption:

Indeed, there are lots of Zoom featured many (including me) have never heard of.
What disturbs me most is how few people are aware of / use Zoom's end-to-end encryption. Holding committee meetings discussing money, exams, tenure reviews etc. without basic security is a bold choice.

I think a lot of people don't know this Zoom feature exists: under "React" there's a "Be Right Back" button that mutes your audio, turns off your camera, and puts a label on your square. And then when you come back you just click the "Back" button.

Hybrid working from home improves retention without damaging performance - Nature
A trial investigating the effects of a hybrid working schedule in a Chinese technology firm in 2021–2022 shows that working from home two days a week improved job satisfaction, reduced quitting and did not affect performance.

The most puzzling fact is that – apparently – there is no physically separate backup server farm. Such kind of incident was bound to happen.
A fire at a government data center in Daejeon on Friday paralyzed hundreds of state-run digital services, exposing weak disaster preparedness and sparking fears of a nationwide disruption of postal services ahead of the weeklong Chuseok harvest holiday.

Nice result by Farhad Yusef-Zadeh et al. Although "surprising" is a strong word, given that we have known most of this (flares vs. quiescent state, flares every few hours, orbiting hotspot) for about 20 years.
