Cosmos DB is Microsoft’s new Azure (i.e. Microsoft cloud) globally distributed multimodel database. There is a good podcast where Rimma Nehme explains it. I’ve long wanted to blog about how to configure USB flash drives to play mp3 files on automotive sound systems. You can downloads Rimma’s podcast as an mp3 available on this page.

To play mp3 files on an automotive sound system, you must have a USB flash drive compatible with your system. You should format your USB flash drive as FAT32. On my car, the maximum size allowed is 32 GB. Larger capacity drives simply will not work.

What I discovered is that the mp3 files need to be placed in a top level folder. I created a folder called Data Platform. Copy your mp3 files into the folder.

Insert your USB flash device into your car and learn something while you commute! As you can see, it’s easy to download an mp3 file and play it through your vehicle’s sound system.

I’ve had mixed results in general getting the mp3 properties to appear on my car’s sound system. Sometimes the properties appear as can be seen in this example of podcasts used in my graduate studies.
