Check Your Mac’s Drive and Reclaim 5 GB of Wasted Space!

July 24, 2015 by Stephen 8 Comments

Since most MacBooks are SSD-only, one would think Apple would be careful about leaving junk around on the drive. But many people are finding 5 GB wasted for a years-old leftover Mac OS X install image! Here’s how to reclaim that space if you’re missing it…

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.

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.

The I/O Blender Part 1: Ye Olde Storage I/O Path

May 23, 2012

This old-fashioned, predictable storage I/O path was deterministic and decipherable: The server, the switch, and the array all had enough information to do their jobs effectively and efficiently.

Begun, the Patent Wars Have

July 9, 2012

Every day, it seems there is a new lawsuit in the mobile phone industry. HTC, Motorola, Google, Microsoft, and especially Apple and Samsung are actively litigating their way through a thicket of patents. The same is increasingly happening in the rest of the IT industry. But is all this bloodshed really about innovation? Or is it, as one federal judge noted, simply a new form of intense business competition?

Marketers: Fudging the Meaning of Buzzwords Matters (To You!)

December 2, 2015

Too many marketers and salespeople play fast and loose with words, but they’re only hurting themselves. Improper usage is embarrassing and causes a loss of credibility with the people they most want to reach. It would be wise to spend a lot more time being correct and a little less time jumping on bandwagons and buzzwords!

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.

Sony QX100 Lens Camera: Ruined by a Flaky iOS App

October 7, 2013

I was thrilled by the possibilities of adding a professional-quality camera sensor and lens to my iPhone, so I immediately pre-ordered Sony’s DSC-QX100 “lens camera”. It held so much promise, not just as a real innovation but also as a major productivity tool. That’s why I’m angry to write this, a scathing review of the horrid software that ruins the QX10 and QX100 experience. Do not buy this device.

Why Buy a NEX-7? Why Sony NEX At All?

October 17, 2011

Your tweets about your NEX have intrigued me a bit…I get tired of lugging my Nikon D90 around with my kids, yet I find the quality of most point-and-shoot cameras terrible…so the NEX seems like an interesting compromise.

Top VMware Blogs 2014: How I Voted

February 25, 2014

Once again, it’s time for vSphere-Land.com’s “Top vBlog” voting. And once again Feedbin and Twitter are full of hundreds of bloggers lamely begging for me to vote for them. And once again, I didn’t base my votes on their begs or my own hunches. Follow along as I explain how I actually voted and why I think you should use the same mechanism. And no, I’m not going to say who I voted for!
