Installing Docker CE Edge for Ubuntu Linux

sudo apt-get purge docker-compose
sudo apt-get purge docker-ce

Those are my personal notes on AWS Solution Architect certification preparation. Hope you find them usefull.

To pass AWS certification, you should have:

Sound knowledge about most of the AWS services ( EC2, VPC, RDS, Cloudfront, S3, Route53 etc,)
Hands on experience with AWS services.

exFAT support on macOS seems to have some bugs because my external drives with exFAT formatting will randomly get corrupted.

Disk Utility is unable to repair this at first, but the fix is this:

Use diskutil list to find the right drive id.
You want the id under the IDENTIFIER column, it should look like disk1s1
Run sudo fsck_exfat -d <id from above>. eg sudo fsck_exfat -d disk1s3
-d is debug so you'll see all your files output as they're processed.
Answer YES if it gives you the prompt Main boot region needs to be updated. Yes/No?
