Desktop virtualization review: VMware Workstation vs. Oracle VirtualBox

Few technologies have had a greater impact on business efficiency and IT productivity than virtualization. While most of the impact has been felt in the data center and in the cloud, virtualization has also transformed IT work on the desktop, where it retains an important role. Here I compare the two leading products in this category: VMware Workstation and Oracle VirtualBox.In executing tests on Workstation 11, I ran into almost no headaches, and in the few cases an item surprised me, I found useful information in the ample VMware documentation. Good documentation has for years been one of the hallmarks of VMware products. This continues to be true.To read this article in full or to leave a comment, please click here(Insider Story)

AMD will skip Chromebooks until prices, features match better, CTO says

AMD microprocessors are relatively cheap and powerful, and they consume little power. So why aren’t they featured in the latest generation of low-cost computers, Chromebooks?The answer, according to AMD chief technical officer Mark Papermaster, is that they just aren’t worth it—yet.“You have to really look at the Chromebook, and what Google’s objective with it is,” Papermaster said, speaking with a small group of reporters on Monday evening during the ISSCC conference. “For us, it's just a business decision, when you need our type of CPU and graphics technology that can make a difference.” AMD Mark Papermaster, the chief technology officer at AMDTo read this article in full or to leave a comment, please click here

Response: We Dislike People Quoting Gartner

John Herbert wrote a wonderful post explaining why he (and a lot of other people including myself) hates seeing Gartner quotes in vendor presentations. Let me elaborate a bit on this apparent anti-Gartner sentiment.

Lisa Caywood from Brocade is an exception – watch the video of her Network Field Day 9 presentation to see how a vendor Gartner slide should look like.

Initial Post with GitHub and Jekyll

Over the past several months, I’ve found myself holding back on writing posts simply because my blog platform does not support the ability to embed code or even change fonts to resemble code, CLI, or working on a terminal. Screen shots are good, but offering the ability to copy and paste is nice, plus it just looks cleaner. This is unacceptable.

Additionally, I have been doing much more with GitHub and markdown. So, after reading what Scott Lowe had done with his migration to Jekyll and GitHub pages, it seemed like that was a great idea. Not only should I be able to improve what I can write, I should be able to decrease the time it takes to write a post. Awesome. The journey shall begin.

Rather than harp on my existing blog platform and that it does not have an export option, I’ve decided not to prolong the process and make this a gradual migration. Going forward, I will be posting the full blog posts at jedelman8.github.io along with ONLY the excerpt at jedelman.com. When you go to continue reading from the excerpt, you’ll then be redirected to the new site. Over time, I really Continue reading

Throw in the bring-your-own-device trend, and that concern gets compounded considerably.Such issues were part of the motivation for the recent launch of the Confide app for confidential enterprise messaging, and they’re also a big piece of the thinking behind the NetSfere messaging service that Infinite Convergence rolled out on Tuesday.Though Infinite Convergence launched its cloud-based messaging service for enterprises on a trial basis last fall, the security-minded offering just became globally available. Device-to-device encryption and administrative controls are among the service’s key features, which add up to end-to-end secure messaging capabilities, the company says.To read this article in full or to leave a comment, please click here
