Samsung Smart TV Thoughts

This is my experience with a Samsung Q90T 2020 TV running Tizen Operating System (OS). I can't say it is a very good Smart TV but the picture is nice. It's riddled with privacy and stability issues. I just hope it works as a dumb TV someday because I don't …

Story about alarm flase positives

ZFS = Amazing Disk Based Backups

Open-E Review, Not a Storage Server

About a year ago, a client needed a NetApp (NFS server), but the IPO wasn't there yet, and the startup's balance sheet was still in the Red. Needless to say after a few trials, we ended up with Open-E DSS because of budget constraints.
