Free up over 100GB of space on macOS High Sierra using Storage Manager

Recently I was invited to participate in the World of WarCraft, Battle for Azeroth Alpha Test. I know you're thrilled (I was too!). However, in order to install the game, it required 40GB of free Hard Disk space. I only had about 30GB free, so there was no way to install it. I have a 1,000 GB hard disk, but 200GB are partitioned for other operating systems, I have over 300GB of Music, and then all my other files take up quite a bit of space. However, I've been running low on space for a while, so I decided to see if I could fix the problem, install the game, and learn something about the Mac along the way....

World Down Syndrome Day

Today is a special day in the lives of my family. It's also a special day for millions of people across the world. March 21st is celebrated as World Down Syndrome Day. Why March 21st? Because March 21st is also written as 3/21. The most common form of Down syndrome is Trisomy 21, which is a third copy of the 21st chromosome (where there is normally only a matched pair). Tri (3) somey 21 or 3/21 or March 21st! If you'd like to learn more about Down syndrome (like why the 's' in syndrome isn't capitalized), there is a great FAQ found at https://www.globaldownsyndrome.org/about-down-syndrome/facts-about-down-syndrome/#freq.

2017 - What I've Read

2017 found my family and I finally settled, if a bit temporarily, in our new home in Cupertino, CA. We're renting and that will be the next major milestone we cross (buying a home). My son started First Grade, my wife continued her position at Cisco, and I'm still enjoying my position at ServiceNow (though I started a new role in 2018). In reviewing the books I read this year (22 titles), they were broken down in the following broad genres: Entertainment - 41% (down from 55%) Non-fiction - 27% (up from 15%) Computing - 5% (down from 15%) Biographies - 18% (up from 7.5%) Self-improvement - 9% (up from 7.5%) In my last What I've Read post,...

Rest in Peace - Christopher J. (Chris) Utley

I've now reached a milestone in my life that everyone dreads, that age when your friends start to pass. I didn't think it would happen this soon. I'm beyond saddened that my first friend to pass from this world into the next was Chris Utley. I was a very young 25 years of age when I met Chris (I'm now 47), so he and I knew each other for 22 years. I had just been recruited from a job at Miami University to run the Internet Operations team at Cincinnati Bell Telephone as they became an Internet Service Provider with a service offering called "Fuse Internet Access". I was told I needed to have a "Webmaster"...

Working around incomplete Ubiquiti UniFi Security Gateway DNS Service

I’ve been having a long-running conversation with various folks in the Ubiquiti Forums here and here regarding the DNS service that is provided by the USG. The USG is just a DNS forwarder and will dutifully take DNS queries from your internal hosts and pass them to whatever DNS servers it received from your Internet provider over DHCP (or perhaps you manually changed them in the configuration). However, I run a medium-sized network on my internal LAN and I have various servers that I wish to access when I’m at home. A couple of examples are: Synology DS1415+ Network Attached Storage Mac mini running macOS Server 3 different Linux Workstations Windows workstation The UniFi CloudKey Controller itself (this...
