“Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you.”

August 11, 2010 By Stephen 6 Comments

Time Machine is one of my favorite Mac OS X features but Apple recently rolled out a “Time Capsule Backup Update”, and included it in Mac OS X 10.6.4, that is causing confusion and concern. In the name of improving “the reliability of your Time Capsule backup,” this update has the unfortunate side-effect of detecting errors in existing backup bundles and forcing users to start a new backup. It happened with two of my Macs so far, so I was keen to find out what’s going on.

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.

Making a Case For (and Against) Software-Defined Storage

January 9, 2014

Everyone is talking about â€œsoftware-definedâ€ everything lately, so it was only a matter of time before industry buzz turned to software-defined storage. VMware and EMC really stoked the flames with a constant barrage of marketing directed in this direction. But how exactly do you software-define storage? And what does this mean?

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.

Mac OS X Lion Adds CoreStorage, a Volume Manager (Finally!)

August 4, 2011

Mac OS X was majorly deficient in that it lacked a volume manager. This wouldn’t seem like a big deal to the average user, but held back the operating system in so many ways. A volume manager brings storage virtualization to an operating system, allowing storage capacity efficiently to be managed and manipulated. But all this has changed in Mac OS X 10.7 â€œLionâ€ with CoreStorage.

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.

From Kipling’s Dirigibles to the Jet Age

May 13, 2012

I don’t get much chance to read for pleasure, but two things I’ve been reading recently spurred my imagination. After reliving the advent of modern transportation in the solid non-fiction Jet Age by Sam Howe Verhovek, I stumbled upon two pieces of speculative fiction from an unlikely source that predated everything presented there.

A High-Tech Water Heater? Yep! Introducing the A. O. Smith Vertex

November 15, 2012

I justify spending six times more on the Vertex 100 for a simple reason: It’ll keep up with the heavy water use in my house. I’m hoping I’ll never have to worry about hot water as long as I live here. The fact that it saves over $100 per year due to energy-efficient design is just icing on the cake.

The iPhone Revolution 10 Years Later

January 9, 2017

10 years ago today, Steve Jobs introduced the iPhone, perhaps the most revolutionary technological product in history. There have been many important products introduced before and since, but nothing else was as groundbreaking as the iPhone. Watching the introduction, it’s amazing to see just how many things were introduced that day that have become integral to daily life today.

How to Get Me to Write about Your Company or Product

March 15, 2012

Blog posts are really, really important for PR and awareness these days. And posts on independent sites like this one are critical to get awareness and search engine ranking. I get dozens of requests every week from companies wanting me to write about them. So I thought it would be a good idea to lay out exactly what it takes!
