iPhone 3.0 Exchange ActiveSync: Better But Not Perfect

May 7, 2009 by Stephen 14 Comments

As the release of iPhone OS 3.0 nears, I set out to discover how the new OS changes the iPhone’s ability to synchronize data with Microsoft Exchange servers using ActiveSync. What follows here is my deductions so far, and is of course subject to change when the new OS is released!

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.

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.

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!

The Prime Directive of Storage: Do Not Lose Data

December 12, 2014

People call on storage devices and systems to do lots of things, from accelerating I/O to copying and sharing data. But at the heart of it all, storage arrays really have just one job: Do not lose data!

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!

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.

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!

Why Are PCIe SSDs So Fast?

June 12, 2013

The world of storage can be confusing, with obscure terms hiding massive differences in technology and performance. Such is the case for the latest PCI express SSDs: They are much faster than traditional SAS or SATA SSDs, but many aren’t sure exactly why. In this article, I will try to explain the real difference.

Microsoft’s Big Chance to Change

August 23, 2013

It takes a truly-remarkable leader to be willing to kill his old golden geese to make room for a new one; so far, only Apple and Amazon seem willing to forgo continuity in the name of profitable destruction. But new corporate leadership at Microsoft might un-stick the company and awaken the once-innovative Redmond powerhouse. The retirement of Steve Ballmer is welcome news.
