Andrew Barto and Richard Sutton have won the A.M. Turing Award for developing the theoretical foundations of reinforcement learning, a key method behind many major breakthroughs in artificial intelligence. 🧵
"Italy may be aiming to bridge the gap until Europe’s IRIS2 system becomes operational. [...] However, critics may argue that the €1.5 billion price tag represents 14.15% of the total IRIS2 budget for just five years of service."
Let's hope IRIS2 is operational on time then...
I have been told to bring contact lenses, as they can be quite expensive over there
Two books and a pack of seashell chocolates in front of a Christmas tree.
This year's Christmas theme is *checks notes* coastal horror?

These results seem way ahead of the expected time-line, no? I'm quite surprised to be honest!
Best part of the signing ceremony for the contracts for IRIS², a European satellite constellation that is delayed and far more expensive than first planned, is when a EU official said, "Let’s agree now: no delays, no requests for extra funding." The audience laughed. spacenews.com/europe-signs...
There are some instances of uncontrolled entry. To my knowledge, they all crashed on uninhabited land. Most of Earth's surface is oceans or sparsely populated...
Fun fact: in order to save the Iridium constellation (66 satellites), the risks of re-entry were intentionally overstated. The fear caused delays, which helped a consortium to buy the system. Even then, in the early 2000s, there were already tons of space debris entering the atmosphere every year.
1: De-orbiting a low Earth orbit can take months or years. It just slowly circles closer and closer. However, the actual burn-up during re-entry only takes a couple of minutes.
2: Most small satellites burn up completely. There are guidelines for controlled de-orbiting.
Starting with Annihilation this Christmas, but already flirting with the other books...
Objekte die nicht im Datenset der Vorselektion sind fliegen dann unter Umständen "unter dem Radar"?
Yes, makes more sense!
Either way, the ratio differs by an order of magnitude...
What is your ratio of peer reviews to publications?
At least for me, there seems to be a never-ending flow of requests for reviews.
Is there any way to stop paper inflation or do I just decline every invitation?
