Is Flash A Disk Or A Cache?

October 22, 2008 by Stephen 2 Comments

There is a battle shaping up in the enterprise storage industry. On one side are those who see flash storage as an upgrade for the disk drive, and on the other are those who see it as a cache between the CPU and the drive. It’s a fundamental difference of opinion – flash chips can […]

greenBytes Embraces and Extends ZFS

September 15, 2008 by Stephen 3 Comments

I’ve long hollered that ZFS is a real storage revolution in the making, but recognized that it still had a way to go before replacing UFS, HFS+, and most volume managers. Well, a little Rhode Island company called greenBytes comes out of stealth today to announce that they’re doing just that – taking the solid […]

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!

The 2018 iPad Pro is a Beast!

The third-generation iPad Pro is a great machine but also a bellwether of change at Apple. It will be very hard for the rest of the mobile and client computing industry to keep up with this kind of progress!

Instapaper for iPad and iPhone Enhances My Web World

June 1, 2010

One of my favorite iPad and iPhone apps is Instapaper. Like the iPad itself, Instapaper seems almost foolishly simple and derivative until you experience it. Then it becomes something else entirely: A product so useful you may ask yourself “how did I ever get along without this?”

The Rack Endgame: Converged Infrastructure and Disaggregation

September 19, 2014

As Iâ€™ve written about what Iâ€™m calling the â€œRack Endgameâ€, the specter of converged infrastructure hasnâ€™t been far from my thoughts. As others have pointed out, disaggregation of servers, networks, and storage doesnâ€™t require a rack-sized stack; it can exist in a rack-mountable chassis and is already on sale!

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.

The Myths of Standardization

December 15, 2011

I certainly benefit from standardization of the world around me, and I welcome interoperability and interchangeability as well as the price and product selection advantages. But I am not blithely focused on standardization above all else. I will happily use a proprietary solution if the alternative is inelegant, ineffective, or insufficient.

How To Sync Your iPad With Your Exchange Server

April 3, 2010

Did your new iPad arrive today? If you’re reading this, you’re probably wondering how to set it up with your corporate Exchange server. The good news is that Apple has been working on Microsoft Exchange integration for years, and the iPhone OS used in the iPad sports fairly complete Exchange ActiveSync support.

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.

Ten Terrible Apple Products

June 14, 2012

I’m often accused of being an Apple fanboy. While it’s true that I love my vast selection of fruity products from Cupertino, I’m not blind when the company makes mistakes. In fact, I think Apple’s mistakes are as enlightening as their successes: They reveal a company that is fallible, sometimes learning but often allowing the junk to rot far longer than other companies would.

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!
