Most people know of Speedtest, the online performance testing website, but most nerds reach for iPerf instead. It’s a self-hosted, full-featured, open-source network performance testing application that runs on almost everything. Today I realized that there’s a free iOS port of the iPerf3 client! It’s super useful!

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.
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!

Virtual Machine Mobility: Of What, and to Where and in What State?
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.
Aerobie AeroPress Review: The Hacker Coffee Maker
Computer geeks like me love coffee, the stronger the better. We computer folks are also known for experimentation and a do it yourself ethic. Some of us even love to get outdoors and toss around a flying disc or football. What happens when you mash up all of this? You get the Aerobie AeroPress, the hacker coffeemaker.
What is VMware VASA? Not Much (Yet)
VMware is adding storage integration features to their flagship vSphere server virtualization product line at a rapid pace. From backup to enterprise array offload, VMware is staking their claim. But information about one new storage feature in vSphere 5 has been scarce: The true nature of the Storage API for Storage Awareness (VASA) is only just beginning to be revealed.
Follow the Yellow Brick Road to the Software-Defined Future
The Software-Defined Datacenter is a great concept, but it just won’t work. The big enterprise companies will never allow VMware (and daddy EMC) to commoditize them out of existence, so useful implementations will be rarer than ruby slippers. The best we can hope for is point enhancements to enable greater virtual machine mobility through SDN and improved storage integration.
Why Are PCIe SSDs So Fast?
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 Overlooked Innovation
It’s fun to bash Microsoft. It’s easy, too, with Apple solidly conquering the high end of the PC and mobile markets and Google’s command of the Internet. But how fair are these articles skewering Microsoft, such as “Microsoft’s chronic lack of innovation” published today at Techworld? I suggest that Microsoft innovates as well as, if not better than, any other massive company. But no one innovates like an outsider.
Defining Failure: What Is MTTR, MTTF, and MTBF?
Most computer industry vendors use the term “MTBF†rather indiscriminately. But IT pros know that systems do not magically repair themselves, at least not yet, so MTTR and MTTF are just as important!
Review: 2013 Ford Flex
The 2013 Ford Flex exceeded my expectations in every driving and utility-related area, but the terrible MyFord Touch system really detracts from the vehicle. I would highly recommend buying a Ford Flex if you’ve got a family of 5 or 6, but try to get one with old fashioned buttons and dials!
