A Month with Localscope

For the last month or so, I’ve been using an iPhone app called Localscope when I travel. It’s a pretty handy little app, designed to integrate with various online services such as Google, Twitter, Bing, and Foursquare, that leverages the iPhone’s GPS functionality and built-in compass to help you find local places of interest: restaurants, coffee shops, ice cream, etc.

VMware ESXi Local Disks Showing as Remote

A little over a month ago, I was installing VMware ESXi on a Cisco UCS blade and noticed something odd during the installation. I posted a tweet about the incident. Here’s the text of the tweet in case the link above stops working:

Is the Pot Calling the Kettle Black?

A recent post by Microsoft on the Windows Virtualization Team Blog titled “Hyper-V VM Density, VP:LP Ratio, Cores and Threads” caught my eye this morning as I was scanning my RSS feeds. In this post, the author (the anonymous WSV_GUY) works through the idea of cores vs. logical processors. The distinction here, in case you didn’t already know, is that many modern multi-core CPUs also support symmetric multi-threading (SMT, also referred to as hyperthreading), which means that an eight core CPU can actually process 16 threads simultaneously and would therefore be considered to have 16 logical processors.

Some Technical Books I'm Reading

My book reading queue has expanded tremendously over the past few weeks as a flurry of new books—some virtualization-related, some not—have landed in my laptop. I really appreciate the authors and publishers giving me the opportunity to review these books, and I wanted to give you a quick rundown of what I’ve been doing on this front.

This is a very short blog post. In fact, it’s probably less of a blog post and more of just a question:

Revisiting Snow Leopard and Time Machine on an Iomega ix4-200d

This post is a follow up to a post from December 2009 discussing the use of Time Machine in Mac OS X 10.6, aka Snow Leopard, with an Iomega ix4-200d. Some people have suggested newer Iomega firmware changes the conclusions of that article, so I decided to see for myself. (Read more...)

What Does it Take to Keep Windows Secure?

My son’s Windows 7 laptop was recently infected with some malware (adware/spyware). Mind you, I try to follow the generally-accepted recommendations for trying to prevent this sort of thing:
