The orientation folks at Apple must have their minds blown out every Monday as we generally have new foks spend the day for orientation.

And be nice to people on the internet. Niceness might not bring out niceness on others (though very often do) but at least it does not push them toward being unpleasant. A lot more can be said about interviews, but the hour is later and I already said a lot 😊

I will give Elon’s Twitter a chance. My stream is mostly about GFX and GPUs. If that remains the same and Tweetbot keeps working with clean interface I will stay. I am not sure why Twitter employees would stay at a privately owned company even if they don’t care who runs it.

This is a fascinating essay on mRDNA and the BionTech/Pfizer vaccine. The mechanisms are fascinating. But more than that how scientific discoveries along the way contributed to the success of the vaccine. Just shows best investment humanity can make is education and science.

I got the first dose (Pfizer) at Santa Clara Valley Medical Center. It was well organized, very helpful employees and volunteers. I am grateful to all the people from the scientists to the front desk people who made it possible.

Man goes biking, flips his bike, hits his head, gets knocked out and doesn't regain consciousness until sometime during the ambulance ride. Apple Watch detects the fall, autodials 911 with his location and EMS has him picked up and in the hospital in <30 minutes. Incredible.

My son and I took turns playing #HorizonForbiddenWest It is a great game with great story, rendering, world building, and interesting side stories. I liked the combat more as well. A great successor to Zero Dawn. I am so sad that we finished it. Really wanted to play more.
