The Biggest, Clunkiest iPad Mini Case Ever: My Old Mac SE!

May 1, 2017 by Stephen 1 Comment

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!

Thoughts on the Modern Miracle of 3D Printing

July 28, 2015 by Stephen Leave a Comment

Although I enjoy my AIO Robotics Zeus 3D printer, I’m under no illusions that it’s an economical or practical device. It’s a toy that takes me into the future, and I love being there!

Adding a Second Ethernet Port to an Intel NUC via Mini PCIe

June 5, 2015 by Stephen 16 Comments

As I mentioned in my previous post about Raspberry Pi power monitoring, I recently built a VMware vSphere “datacenter” from three Intel NUC mini PC’s. One limit of the NUC is that it has just one Ethernet port. But there’s a Mini PCIe slot inside the fourth-generation NUC that can be used to add a second Ethernet NIC!

Having Trouble Keeping Your Cool? You Need Some AC Infinity Fans!

March 31, 2015 by Stephen 2 Comments

I’m pleased with the solution to my cabinet cooling problems. The AC Infinity fans are quiet and effective, especially in combination with the AI-ATC smart controller. My drives can now keep their cool with the cabinet door closed and I had fun designing and 3D printing the mounting bracket. The best part is the cost: The whole package of fans and controller cost under $60 shipped!

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.

The Rack Endgame: Open Compute Project

September 17, 2014

On reading my thoughts about the evolution of enterprise storage, many pointed out that this looks an awful lot like the Facebook-led Open Compute Project (OCP). This is entirely intentional. But OCP is simply one expression of this new architecture, and perhaps not the best one for the enterprise.

FCoE vs. iSCSI – Making the Choice

May 20, 2011

iSCSI is an excellent choice in situations where Fibre Channel investment is nonexistent or badly in need of wholesale upgrade. FCoE, on the other hand, is likely to take over in high-end enterprise shops. It is relentlessly promoted by major vendors, and it seems that they will force the upgrade eventually.

My Visit to Bletchley Park

August 3, 2012

Bletchley Park is much more than a museum. For those interested in the history of computing, like me, or World War II buffs, it’s a must-see. The reconstructed Bombe and Colossus computer are truly breathtaking, and I find myself drawn to the stories of codebreaking that took place here. I highly recommend a visit!

Scaling Storage Is Hard To Do

June 4, 2013

Data storage isn’t as easy as it sounds, especially at enterprise or cloud scale. It’s simple enough to read and write a bit of data, but much harder to build a system that scales to store petabytes. That’s why I’m keenly focused on a new wave of storage systems built from the ground up for scaling!

Rocking Out With the Topping VX1 Desktop/Bookshelf Amplifier

October 6, 2015

A few months back, I asked folks on Twitter and LinkedIn for recommendations for a desktop amplifier for a pair of bookshelf speakers. I ended up with a Topping VX1, one of the many “Class-T” digital amps lauded by audiophiles for their excellent sound reproduction. Boy am I impressed! It’s rare that such an inexpensive gadget (around $100!) delivers so much performance!

Virtual Machine Mobility: Of What, and to Where and in What State?

January 16, 2012

Moving cold virtual machine images from system to system, or even across great distances, is one of the main selling points of server virtualization. But it becomes much more difficult to manage movement of virtual machines that are still running, especially outside cluster or across WAN links. When talking about virtual machine mobility, it is important to consider what is being moved, the state it is in, and where it is going.

Generation 3 drobo: Fall In Love All Over Again

April 9, 2015

I remain a huge fan of drobo generally, and the third-generation drobo remains the best choice for home storage. It’s the perfect storage device for the long haul, and the performance improvements make it a no-brainer. Get one.

Co-Processors, GPGPU, and Heterogeneous Computing

June 26, 2017

I’ve been thinking a lot lately about microprocessors, from the many-core CPUs that AMD and Intel introduced recently to the massively scalable GPGPU processing that’s taking machine learning by storm. After years of consolidation on commodity x86 CPUs, it seems that the computing paradigm is turning again to specialized offload processors. This trend towards heterogeneous computing will change the face of hardware, from mobile devices to the datacenter.
