vSphere 6: NFS 4.1 Finally Has a Use?

February 3, 2015 By Stephen 2 Comments

Way back in the 1990’s, UNIX admins delighted in upgrading from NFSv2 to NFSv3. Then NFSv4 came around and … crickets. Now VMware has become the first major/useful/mainstream application for NFSv4.1, so the floodgates are open! But are they?

It’s time once again for Storage Field Day! As most of my blog readers are aware, I run the Tech Field Day event series, bringing together experts in various IT fields with key companies for a few days of deep technical discussion.

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!

The End of Unlimited Data – Part 1: The Buffet

June 2, 2010

The headlines are all over the blogs: AT&T announced today that they are doing away with “unlimited” data plans and replacing them with limited packages at lower prices. I’m not going to repeat the news – Boy Genius Report has the best overview I’ve seen. Instead, I’m going to explain why I think this is a positive move for everyone involved, including AT&T, the customer, and the US wireless phone industry as a whole. This first post talks about the buffet mentality that got us here.

Introducing Rabbit: I Bought a Cloud!

September 10, 2020

We live in a world of cattle, not pets, and Kubernetes rules the roost. I’ve been meaning to spend some time getting up to speed on the latest but didn’t have enough hardware to make that happen until now. I recently bought a whole pile of surplus hardware so I will be able to experiment with orchestration and container platforms in the office.

Frequent Flier Kung Fu for Novices

March 12, 2012

If you’re careful, even an infrequent flyer can rack up valuable points and maybe even elite status. But don’t do anything foolish, and don’t be fooled by the promises of first-class treatment. Even top-tier frequent flyers sit in coach most of the time!

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!

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.

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!

We Live in the Future: Robotic Cat Litter Boxes!

May 8, 2010

This post is a bit of a break from my usual gadget-fest, but the object in question isn’t that far off: It requires electricity, costs more than average humans can justify, and simplifies a task we’ve all been doing fine up until now. That’s right: An overly-expensive electric cat litter box. Predictably, I love it.

Once you encrypt your MacBook’s drive with FileVault 2, you’ll never even know it’s there. But if you ever lose your machine, you can rest easy knowing that your data is safe. Considering how well this solution performs and that it is included free of charge, there is no reason not to use it!
