How Can I Play Music To All My Rooms?

Echo

Episode 1652

David from Anaheim, CA

David wants to stream music to multiple rooms in his house. MultiRoom music is a challenge because it has to sync from room to room with no latency. But it is doable with Amazon Echo. He can get a dot in each room and add some speakers and it'll work. The Echo is smart enough that he can even command it to play in different rooms as well. The Amazon Echo Input connects to one's own speakers, and right now it's only $10.

Will Starlink Satellites Ruin the Sky for Astronomers?

Starlink

Episode 1652

Louis from Hollywood, CA

Louis wants Leo's thoughts on the Starlink project by Elon Musk and SpaceX. Leo says he has mixed emotions. He likes the idea of gigabit speeds anywhere in the planet, but he's not sure he's supportive of 42,000 satellites in low earth orbit. They are already interefering with astronomy, and there's less than 125 of them so far. Astronomers are already complaining, and SpaceX is working to make changes to the reflectivity of future satellites to be launched. Gwen Shotwell, of SpaceX said that nobody thought of that problem when they first conceived of it.

2015 iMac

Episode 1651

Angela from Dartmouth, Nova Scotia, Canada

Angela has a 2015 Mac and when she shuts it down, it turns back on. Leo says it's an incomplete shutdown, with some app hanging it up. A wipe and reinstall of the OS should make it go away. Make sure you backup your data first.

Can I partition an SSD drive?

Solid State Drive

Episode 1651

Larry from San Francisco, CA

Larry is building a new computer and wants to know if an M.2 SSD drive can be partitioned like a regular hard drive. Leo says when installed, M.2 drives are just like any other drive and can be partitioned as you need. Leo advises, though, that users should keep their data on a regular spinning drive and keep the SSD drive for your OS and applications. The OS really wants apps to be on the same drive, and it's easy to put a second spinning drive in. But if you partition a drive, you're setting an artificial limit on what you can put on it. So you don't really need to partition it.

Sam Abuelsamid

Episode 1651

Sam joins Leo to talk about something a bit different, but still an electric "vehicle." It's an electric skateboard. It was a GM concept from 2001, and it used hydrogen fuel cells. The concept has been adapted over the last 20 years to just about all dedicated electric vehicles. Leo wonders if Detroit is working to make car manufacturing more modular, so you can mix and match components for different electric models. Sam agrees.
