πŸ“£THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms).

I believe that research works best as a team sport, with all the obvious benefits, and think that teams work best when there are chances to get to know each other away from the desks from time to time. For example, when there is a tricky flat tire to fix together midway through a bike trip... 🚲 🌬️ πŸ”§

I had a great time at IEEE #ICDCS 2025. First time that I attended a conference without a talk or helping to organize, so this was a new experience! Of course, also rather nice to attend a top conference after 10 minutes on public transport (and after dropping off the wee one at nursery too ☺️)

Apparently some folks are still confused about how much CO2 in the air has grown due to human activities. It's increased by more than 50%, which means over one third of all CO2 in the air is due to us.
