I was listening to the New Year’s Day concert by the Vienna philharmonic and wondered who one of the composers was so used a popular song recognition app. (I expected it would make some fuzzy match on the piece and give me the name + composer). To my amazement it did give the name and composer but as played by the Vienna philharmonic in 2005 in the same location. The orchestra does not have the same members as 19 years ago, nor was it the same conductor, so it seemed the piece was matched on the acoustics of the Musikverein where they were playing, which I found astonishing.
I never used to use my phone’s flashlight function because it’s so bright, I assumed it would suck the battery dry. But recently I had it on for like 15 minutes and it only used up one or two percent. Amazing.
