Duncan Epping is offering his books vSphere Clustering Deepdive 4.0 and 5.0 for free, but only today and tomorrow.
For more info take a look at his great blog:

In WordPress an RSS feed can easily be added and by default it will show all the blog posts. I however wanted to have an RSS feed only containing blog posts of a specific category. Since I couldn’t easily find it on wordpress.com I googled around a bit and these are my findings.
For even more options, take a look at this great article:

Even though the website http://office.microsoft.com provides a comparison of the different Office 365 plans, it is not always entirely clear which features are available or what the restrictions are.
Luckily, Jasper Osgaard created a great blog post comparing the different plans in more detail without having to go through tons of documentation:

About 3 weeks before the upgrade took place, I received e-mails informing me about the upcoming update. It included the plan date and also mentioned I could postpone the update. As the date of the upgrade approached I also received mails with information of new features and what had to be done.
The upgrade itself took place on the date that was communicated to me and when it was done I got a mail informing me that the upgrade had been completed. When I logged on to the Office 365 admin center (https://portal.microsoftonline.com/) I immediately found this to be a big improvement. It also showed me some alerts containing links to information about changes and tasks that still needed to be performed like upgrading SharePoint sites.
I didn’t expect any big issues, but I was a bit worried if my SharePoint customizations would keep working correctly:
It is possible to leave the SharePoint site the way it is (at least with this upgrade), but you can also upgrade it and take advantage of the new options. If you are considering upgrading the SharePoint site, you can perform a health check and you can also request an upgrade evaluation copy of the site collection before you actually upgrade.
Probably because of my customizations, the Site Collection Health Check found some problems related to Customized Files that could result in unexpected visuals or behavior.
For now, everything seems to be working fine though on my upgrade evaluation copy of the site collection, so I’ll probably upgrade my site collection soon. If you want to, you can take a look at both the pre-upgrade SharePoint site and the post-upgrade SharePoint site. The evaluation post-upgrade version will only be available until the 23rd of June.
What I did notice, is that the interface of the services have improved and have also been changed to better suit for touch devices. By example the white space between navigation items seems to have increased and everything is a bit bigger.
After the upgrade, I also had to restart some Office 2013 apps once.
Of course the upgrade to Wave 15 provides many more advantages, but in this post I only wanted to share my service upgrade experience without really changing anything. All in all, I think the upgrade experience went very well.
The PowerShell Summit took place in North America in April and many of the prominent PowerShell people were there. And from what I read there were a lot of great presentations.
The PowerShell Summit 2013 North America conference schedule can be found here. Thanks to Don Jones and PowerShell.org (most of) these sessions are available for download: http://powershell.org/wp/2013/04/22/summit-downloads/
Videos are available here:

So even if you weren’t able to attend, you can still learn from their presentations. Or if you did attend, you can review them again.
The recordings for “Using Microsoft VDI to Enable New Workstyles Jump Start” are available now on Microsoft Virtual Academy (MVA).
These Jump Starts are a great way to quickly get up-to-date about a subject. Also there’s a great team of people working behind the scenes to answer questions and provide more detailed resources. Other attendees often also share their experiences and provide valuable insights. So be sure to check out the Q&A log as well.
Microsoft Virtual Academy (MVA) is hosting the “Windows Azure for IT Professionals Jump Start” at May 16th. Information and registration is available on the website: https://www.microsoftvirtualacademy.com/liveevents/Windows-Azure-for-IT-Professionals?CR_CC=200206715
I’ve attended a couple of Jump Starts and I think it’s a great way to quickly get up-to-date about a subject. Also there’s a great team of people working behind the scenes to answer questions and provide more detailed resources. Other attendees often also share their experiences and provide valuable insights.
Also it’s only been a couple of weeks since Windows Azure IaaS is live in production backed by an enterprise SLA, supported by Microsoft Support, and ready for your production applications. Therefore it is a great time to start learning more about it.
I hope to see you there.
After the great first Dutch PowerShell UserGroup (DuPSUG) meeting last November, the 2nd meeting will be held on the 6th of June in Hilversum at InterAccess. At http://www.dupsug.com you can find more information about the event including a schedule and a registration form.
I really liked the previous meeting, so I’m going to attend this time as well. I hope to see you there.
PS: The number of attendees is limited, so don’t wait too long.
In the beginning of June, the new Intel Haswell CPUs will be available. Besides the regular improvements like being faster, having better energy efficiency and having better graphics capabilities, these new CPUs will also include VMCS shadowing (Virtual Machine Control Structure Shadowing).
Basically it’s a feature that allows you to run a hypervisor (like VMware, Hyper-V, Xen Server) and create another hypervisor as a VM beneath it. This is also called nested virtualization.
Some of you might say, “Hey this is not new, I’ve already done this with VMware!”. The difference however is that the current method uses some sort of emulation that does not directly access the hardware. And even though it’s great for testing purposes, the performance is suboptimal.
With the embedded hardware supported VMCS shadowing in the new Intel Haswell CPU the nested hypervisor can directly access the hardware, which should improve performance. Also, it might even make it possible to use non-VMware hypervisors in a nested virtualization scenario.
Of course as always, we’ll just have to wait and see how the performance will be in real-life. It’s also not clear to me yet if hypervisors need to be updated to be able to leverage this option. Nonetheless, to me it sounds very promising and I look forward to playing around with it.
For more information read this great article by Gabe Knuth called “Could VMCS Shadowing (a.k.a. nested VMs) from Intel’s new Haswell processors be what Bromium needs to work in VMs?”. When you use the links in the article you will be able to get more information about the Intel Haswell CPUs including benchmarks and more detailed information about VMCS shadowing and use cases.
[EDIT 08-06-2013] Citrix is working hard on integrating VMCS Shadowing / Nested VMs in their products:

If you’re planning to build / buy an Intel Haswell based computer or Home Lab, be sure to look into the confirmed USB3 bug in the chipset. Also unfortunately the DDR3 prices have increased substantially (almost 50%) over the last half year.
