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.

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.

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.

EMC Redefine Possible (TL;DR Edition)

July 9, 2014

EMC made quite a few announcements today at their “Redefine Possible” event in London. There’s a lot of coverage out there already, so I decided to present a summary of the whole thing in “too long; didn’t read” (TL;DR) fashion.

Most of my readers know that I love getting my hands on the latest high-tech products. But, last week, I spent a few hours insideï»¿ one of the latest and greatest products on earth: United’s latest Boeing 787 “Dreamliner” composite jet! Here’s my “butt-in-seat” review!

What’s (Still) Wrong With Dropbox For Business

April 17, 2013

I am a heavy (and paying) user of Dropbox, using it both for business and personal storage and synchronization. Although I find the service incredibly useful, Dropbox is far from perfect, especially for business users. So I thought I would take a few moments to talk about what I’d like to see Dropbox improve.

What You See and What You Get When You Follow Me

May 28, 2019

Social media ought to be social, not just a broadcast platform. That’s my feeling at least. It’s been a while since I’ve ranted about “write-only” social media accounts, so I thought I might as well do it again. And at the same time, I thought I would update you on my promise to the people who read, follow, and interact with me online.

Here’s Something Your Raspberry Pi Can’t Do: Gigabit Ethernet and SATA in the Olimex A20-OLinuXIno-LIME2

May 25, 2016

I’ve really enjoyed experimenting with the Raspberry Pi, and have even deployed a few as UNIX servers in my home and office network. The quad-core performance of the latest Pi models is awesome, but serious I/O limitations remain. With just one USB 2.0 interface shared for all network and storage operations, you aren’t going to […]

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.
