Catching up on announcing a few new RunAs RunAs Radio shows that I've neglected to mention here over the past couple weeks. We publish a new episode each and every Wednesday. The show has been live since mid-April and it's been pleasantly surprising to see how quickly it's taken off!

Anyhow - RunAs Radio Shows 7, 8 and 9 are now online. Discussions in these shows include disk and file encryption and the TrueCrypt open source software, Public Key Infrastructure (PKI) and what it means to you as an IT professional, and Microsoft Operations Manager (MOM) 2007, a great tool for managing and monitoring your enterprise, whether small or large.

Links: RunAs Radio web site and RSS feed

We always welcome your input and ideas for the show - Just email and let us know what's on your mind! We might even read (and answer) your email "on the air," and we are always interested to know what you would like to hear about as we book our guests.

I just arrived in Florida this evening for TechEd, so I am catching up on some news, and found this at It's good news in the "let's make effective security easier and better" category:

At TechEd 2007 this morning, Microsoft's senior vice president Bob Muglia generated the biggest applause of the day (not related to the Christopher Lloyd cameo) by announcing the new Server Core installation option in the forthcoming Windows Server 2008 will have as one of its ready-made "roles" the ability to rapidly appropriate Internet Information Services in a command-line-only environment.

The Server Core option allows you to run Windows Server without all the fancy Windows stuff - I other words, it's truly bare-bones and includes only what you really need.

UPDATE: On the TechEd floor today I learned that the "server core" implementation of IIS7 won't support ASP.NET applications - just HTML and ASP type stuff. Hopefully ASP.NET will be an option in the future.

From Microsoft, here is a description of the concepts behind the Server Core installation option:

The Server Core installation option of the Microsoft Windows Server 2008 operating system is a new option for installing Windows Server 2008. A Server Core installation provides a minimal environment for running specific server roles that reduces the maintenance and management requirements and the attack surface for those server roles.

The Server Core installation option of Windows Server 2008 provides the following benefits:

  • Reduced maintenance - Because a Server Core installation installs only what is required to have a manageable DHCP, File, Print, DNS, Media Services, AD LDS, or Active Directory server, less maintenance is required.
  • Reduced attack surface - Because Server Core installations are minimal, fewer services and applications run on the server, thereby decreasing the attack surface.
  • Reduced management - Because fewer applications and services are installed on a server running the Server Core installation, there is less to manage.
  • Less disk space required - A Server Core installation only requires about 1 gigabyte (GB) of disk space to install and approximately 2 GB for operations after the installation.

You can keep up to date with the Server Core team's efforts on their blog, and participate in the Server Core TechNet forum.

Google holds it secrets close, as it should. One of its most valuable assets (probably its most valuable) is still its search engine, and because it's the end-all-be-all of Internet searching, how well it works is very important to the company. Add to that the relevance and accuracy of searching as it relates to Google advertising revenues, and the importance becomes quite huge.

The New York Times published a story this morning about the Google search inner sanctum, a bunch of people who tweak and adjust the search algorithms used to get people what they're looking for on the web. It's a good article and dives deep into the work the team does and how much more accurate search has become.

“Expectations are higher now,” said Udi Manber, who oversees Google’s entire search-quality group. “When search first started, if you searched for something and you found it, it was a miracle. Now, if you don’t get exactly what you want in the first three results, something is wrong.”

It's an interesting read, well worth the time. And think about how much storage is required for this:

And Google does more than simply build an outsized, digital table of contents for the Web. Instead, it actually makes a copy of the entire Internet — every word on every page — that it stores in each of its huge customized data centers so it can comb through the information faster. Google recently developed a new system that can hold far more data and search through it far faster than the company could before.

Find out more about Google's PageRank as well as a little of what they call "signals" - cues and other information the search engine algorithms generate and use to determine what you see when you search and why.

As I mentioned recently, I went to a sleep study center a couple weeks ago and stayed overnight, where I learned I have an apnea problem. A couple days ago I returned to the sleep center to spend another night, this time with a CPAP (continuous positive airway pressure) machine and a mask. It was in interesting night.

A little pill helped me fall asleep that night, but throughout the night I woke up from the weirdness of the mask on my face. Sometime in the middle of the night I had a pretty bad "mouth leak," meaning my mouth was opening so the air pressure from the machine and mask over my nose was flowing right out my mouth. So the technician came in and put a chin strap contraption on me, which was a bit too much - I have to say I felt like I was in a head cage or something.

But it did work - Even with the interruptions, I felt noticeably more refreshed than ever the next day as I drove to work and went about my daily work routine. I also had some super-crazy dreams on that first night with a CPAP machine at the sleep center, ones which I actually remembered. And that pretty much never happens to me these days. My doc told me my REM sleep (deep sleep where you dream) was pretty much too broken up to be of any good to me based on the number of apnea episodes I was having, so he was not surprised at the dreams, or the intensity/craziness. He said there's a theory of REM rebound, where a person who has had badly fragmented sleep suddenly is able to enter extended REM sleep, so the brain has a lot of clutter to clean up and the dreams can be intense or active.

I was sent home with a CPAP machine (actually it's a BIPAP machine that has a humidifier - more on that later) and a couple different masks to use. One of them is very small and fits under the nose, and the other one is more of a traditional full-face mask. I tried the nasal pillow model last night with limited success (it made the lower bridge of my nose pretty sore by morning), so tonight I am trying the mask that covers both the nose and mouth in hopes it will provide better results since I am told I am a "mouth breather." It turns out there are a lot of masks out there, with new ones coming out all the time, so it's a matter of trying them til you find the one that works best for you. Most take some getting used to, they say.

At some point here I'll get all geeky and write about the hardware and what it does (the BiPAP machine is computerized and has a smart card like thing that I can pull out and take to the doc so he can see how well I am doing on the machine - pretty cool). I'm lucky to have really good health care insurance that recognizes the preventative value of this stuff and covers the significant majority of the equipment cost

Any CPAP tricks out there that people know of? How long did it take people to adjust, I wonder?

Scott Hanselman posted a great list of items to look at and check into when you're using virtual machines with Virtual PC (or server) and need to ensure good performance. It's not automagical to have things work at best performance, so getting educated and knowing what to do and when is important.

His list is here:

I'll be heading for TechEd next week in Orlando, Florida.

Richard Campbell and I will be recording some RunAs Radio interviews on the Virtual TechEd stage, and I am looking forward to catching up a bit in terms of the latest and greatest IT technology. The past several months of my work (and life) have been pretty much consumed with the acquisition of the company I work for, so I am looking forward to the chance to focus my mind back on the rest of the technology world for a change.

Anyone else planning to be there? Let me know!
