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!

A Watch Guy’s Review of the Apple Watch

April 27, 2015

Is the Apple Watch a personal communication revolution like the iPhone, a well-executed gadget like the Apple TV, or a total miss? Does it mark the end of the the world as we know it for watches? And what’s it like to use one? I’m a watch guy and a gadget guy, so perhaps my perspective will be of some value.

SMB 3 is Going to be Huge, in both Scope and Impact

May 6, 2012

Microsoft is about to release the third major revision to their ubiquitous network storage protocol, SMB. Windows Server 2012 and Hyper-V 3 will really highlight this technology, and I predict it will transform the way people think about networked storage for Windows systems. But SMB 3 is big in another way, too: there are tons of new features, and not all will be implemented by everyone.

It’s Fine To Mount Hard Drives On Their Side Or Even Upside-Down

August 13, 2016

Have you ever wondered if mounting a hard disk drive on its side or even upside-down affects its lifespan or reliability? According to every drive manufacturer, it’s perfectly acceptable to mount a hard disk drive in any orientation as long as it’s not tilted and has sufficient cooling.

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!

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).

A Complete List of VMware VAAI Primitives

November 10, 2011

VMwareâ€™s introduced the â€œvStorage APIs for Array Integrationâ€ (VAAI) in vSphere 4.1, and block-heads like me went nuts. Weâ€™ve been trying to integrate storage and servers for decades, and VMwareâ€™s APIs finally allowed this to work in truly seamless fashion. But the world of VAAI is a thicket of bizarre naming and puzzling functionality. Some VAAI primitives are ignored or even hidden! Letâ€™s take a look at the complete list.
