Years ago, I had a SPARC workstation running SunOS that used John Conway’s Game of Life as the screensaver. I loved watching it, and it’s one of the biggest things I’ve missed about using that workstation and OS. In 2018, I decided to write a screensaver for macOS that simulated the Game of Life. I’ve used it for the past couple of years on my own Macs, but never released it publicly. When I learned that Dr. Conway passed away earlier this week, on April 11, 2020, I decided to release this screensaver to the general public as a tribute.

I wonder how many people will buy the set of Mac Pro wheels and just install 2 of them…picking up just one side of the Mac Pro when they want to move it.


Screw you, Apple Watch. I just got back from a 45 minute outside walk, which you counted as only 5 exercise minutes even though I started a “workout”.

With work finally easing up a bit, I found some time to edit this video I recorded a few months back. In the video, I go through the process of adding a new disk to a Dell PowerEdge server and using it in VMware ESXi. Then I add a second disk and migrate to a RAID 1, and a third disk to migrate to a RAID 5, expanding the disk capacity along the way. All without rebooting the server.

Neil Peart was one of the finest drummers I’ve ever heard. If you haven’t heard his solo of O Baterista, you’re missing out. Such an amazing talent lost…

Spending time tonight learning Final Cut Pro.  I’ve been meaning to try it out for years now, but never had a chance.  I downloaded the trial version a couple days ago to give it a go.  Loving it so far…


A “reasonable” configuration that I would configure if I was speccing my own desktop (16 core / 96GB / 2TB) comes in at just under $10k.


The $64000 question of how much a fully specced-out Mac Pro costs is actually not far from the truth. It’s $52,748. ($500 more for the rackmount)


It’s not everyday you see 1.8 GB/s long enough to grab a screenshot.  Copying 122 GB of files from a Thunderbolt SSD RAID to the internal NVMe.

While I’m disappointed in the stability issues plaguing macOS Catalina and iOS 13, it’s impressive to see how rapidly Apple is pushing bug fixes recently.  


Spent the last two days at The Ohio Linux Fest. The last time I attended had maybe 150 attendees back in 2005. Now they have over 700 people registered and several conference tracks. Great to see the growth.
