Powering Rabbits: The Mean Well LRS-350-12 Power Supply

October 18, 2020 by Stephen 3 Comments

My cloud of Intel NUC servers are powered by a generic slim 12 volt power supply from Chinese company Mean Well. This is a popular power supply with hobbyists and is widely available worldwide. I replaced the non-functional fans and 3D printed a cover for the terminals, and now two of my three “Rabbit” trays are up and running happily.

What happens when you mix two old, broken things together? In the case of my Mac SE and iPad mini, the result was pretty cool! Meet my desktop videoconferencing system!

3D Print a Seagate GoFlex Dock Adapter for 2.5″ Hard Disk Drives

March 26, 2015 by Stephen Leave a Comment

The Seagate Free Agent GoFlex Docks were an excellent product, allowing interchange of hard disk drives and connectivity protocols. They made USB 3, FireWire, and even NAS docks for these hard disk drives. But the connector is standard SATA and could be used with any drive. So I created a 3D printable adapter and released it on Thingiverse!

GPS Time Rollover Failures Keep Happening (But They’re Almost Done)

This is week “1111111111” in the GPS system. Tomorrow morning it will roll over to week “0000000000”. How well will various systems handle this change? Not well, judging by what we’ve seen so far!

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

Hands-On Review: Unicomp Spacesaver M Keyboard for Mac

July 3, 2012

I would not hesitate to recommend the Unicomp Spacesaver M to Macintosh users used to an original IBM Model M, and I am admittedly a tough customer. I wish that Unicomp would update their website, packaging, logo, and keyboard graphics, but none of this really matters as your fingers press the keys. If any keyboard is worth $100, it is the Unicomp Spacesaver M!

The Four Horsemen of Storage System Performance: The Rule of Spindles

August 25, 2010

Why do some data storage solutions perform better than others? Mechanical performance, RAM caching, I/O capacity, and the intelligence of the system all have a part to play. Today we examine the rule of spindles: Adding more disk spindles is generally more effective than using faster spindles.

Download My Free E-Book, “Essential Enterprise Storage Concepts”!

April 4, 2017

I’ve got a lot to say about storage, as you might have noticed from reading my blog. So I finally sat down and wrote a book on enterprise storage. Now you can download the e-book for free, thanks to support from my friends at SolarWinds!

Why Big Disk Drives Require Data Integrity Checking

December 19, 2014

Hard disk drives keep getting bigger, meaning capacity just keeps getting cheaper. But storage capacity is like money: The more you have, the more you use. And this growth in capacity means that data is at risk from a very old nemesis: Unrecoverable Read Errors (URE).

The Terrifying True Story Of Virtual Machine Mobility

December 22, 2011

Virtualization of server, network, and storage services illuminates the link between physical resources and functional applications. A running virtual machine can instantly move from one server, network adapter, HBA, or LUN to another. And when it happens, traditional components have no idea how to react.

Sony NEX-7 Hands-On Review Part 1: The New Super-Camera

March 26, 2012

It took over five months, but Sony finally delivered my NEX-7 kit on March 8 (my birthday, natch!). After using the camera for a few weeks, I can say it’s exactly what I hoped it would be: A worthy upgrade over the NEX-5, and perhaps the best enthusiast camera on the market. But it’s not without flaws, including some surprising shortcomings. Here’s my hands-on review!

Review: Blue Snowball USB Microphone

March 31, 2010

I’ve really jumped into recording podcasts, and am also an avid audio and video conference user. Wanting better sound, I upgraded my Logitech microphone to the highly-regarded Blue Microphones Snowball desktop USB microphone. Here are my initial thoughts.

Preserving Your Credibility Is Your Prime Directive

June 4, 2012

I hope this post isn’t too “out in left field” but I thought it needed to be said. Independent social media has evolved into a powerful mechanism to influence belief, behavior, and (yes) buying. I take my little dollop of influence very seriously, and feel an incredible responsibility to live up to the trust placed in me by others. I will try every day not to let you all down!
