This is the first of a two part post on my trip to Las Vegas for the Microsoft Mix 2009 conference. This first part will focus on Las Vegas from the tourist point of view, with part two focusing on Mix itself.

Hotel

This was my first time in Las Vegas and I stayed at the Trump Hotel, which is only a 5 minute walk from the strip (Las Vegas Blvd). Located on Fashion Mall drive, it is on the North end of the strip (Fasion Mall Drive is across the street from the Wynn). I highly recommend the Trump Hotel, and both my wife and I enjoyed our stay there. The room was only $89/night plus the mandatory $15 resort fee (which seems to be common).

The rooms themselves are like a studio apartment, complete with enough of a kitchen to cook some basic meals, and a huge marble tiled bathroom with a whirlpool tub. There is a 32” LCD TV in the living area, and a 9” LCD in the bathroom mirror. I’m surprised they didn’t have a LCD TV next to the toilet to go with the phone. I didn’t do any cooking, but I did make use of the refrigerator to keep some beverages available.

They have a pretty nice exercise room, and a pool area with lots of room to just layout in the sun. The pool isn’t fancy, there are no fake rocks, slides, or kiddie play areas, but it is quite functional and heated. In addition to the pool, there are two hot tubs and two rows of cabanas available for rent. While I didn’t walk around to the other side, I noticed on the model of the hotel property which was in the lobby, that the other side had additional room for sun bathing. I saw a couple of kids in the pool, but for the most part, it was pretty quiet, and I was even able to get in some “lap” swimming on Thursday night before the pool closed. 

The Strip

I spent a lot of time walking up and down the strip, before and after my wife came. There is quite a parity between walking the strip at night, and heading over to the Venetian for the conference in the morning. At night, it’s like you see in the movies, big crowds and bright lights, while in the morning it’s like any other busy downtown city street. I noticed a good number of people out jogging on the strip, and I just couldn’t pass up the opportunity to go running in the idea morning weather. Maybe it was the result of being inside all winter, but the air smelled very fresh in the morning, and I really enjoyed the two runs I got in. I was pressed for time, so I was only able to do a 30 minute run (15 out and 15 back), which got me as far south as south end of Caesars Palace one morning, and up to the Stratosphere on the other morning. 

A good amount of my time was spent in the Venetian and Plazo, since that is where the conference was, and by the end of the week, I felt pretty good at navigating the labyrinth under the two hotels. I think that the Venetian and Plazo were my favorite hotels to wander around in. My wife really liked Caesars Palace and the Forum shops (so much that I had the pleasure of walking all the way thru the Forum shops twice) due to the roman architecture and theme. Everyone says the Wynn is awesome, but I must have missing something because I was unimpressed given the high praise.

I think I ended up catching the TI Pirates/Siren show 3-4 times during the week. You can get a pretty good view from across the street, and it’s usually less crowed on the north side (closest to the Fashion Mall). However, I would recommend watching it at least once from the “front row” which would be on the bridge that leads to the hotel, closest to the Siren’s ship. Also, the show is more impressive in complete darkness, as you get to see the full light show.

Also at TI, is a most excellent brunch buffet, offered on Saturday and Sunday until 4pm I believe. Without champagne, it’s only $17/person, which is really cheap compared to other buffets and sit down restaurants in Vegas. Considering a large orange juice would easily run you $3/glass, and I had two, that’s $6 right there. The line was long, but moved fast. They have a VIP line, so if you hunt around, you can probably get your hands on some VIP tickets and skip the line. Other notable dining experiences were Del Torro (Lamborghini resturant) in the Venetian, and the Harley Davidson Cafe towards the south end of the strip.

Shows and Attractions

We saw two Cirque du Soleil shows, Ka at the MGM Grand and Mystere at TI, and they were freckin awesome. I was a little apprehensive about spending $400 on show tickets, but it was worth it. I highly recommend spending the extra money and getting the best possible seats you can. We had front row seats for Mystere and were able to see everything in such detail, from the performers costumes to the expressions on their faces. The half price ticket place was actually a pretty good deal. Right now if you buy online thru Ciruqe Du Soleil, you can get two category 1 tickets for $257.50 after a 25% discount and all fees, where as we only paid $218 a the half price ticket place.

Ka is the only Cirque du Soleil show that has an actual story line to it, set in ancient china I believe and follows the ordeal of a young brother and sister (prince and princess) caught in the middle of a war. It is a high energy performance with incredible choreography, stunts and martial arts. My wife described it best as live action anime. Check out the trailer on youtube, and another video that shows some of the mechanical engineering behind the scenes. Mystere is similar to Ka without the storyline and martial arts influence, however it is no less incredible. It would be hard to choose just one. Next time we are looking to go to O, and then change things up with the Blue Man Group.

On our last full day in Vegas, we rented a BMW Z4 convertible and drove to the Hoover Dam. The last 4 miles to the dam was bumper to bumper traffic, as all the weekend visitors were trying to get back to Arizona, and it’s only a 2 lane road over the dam. However, they are working on a 4 lane highway and brand new bridge over the river just south of the dam, which looks impressive itself. We opted for the 45 minute power plant tour, and felt a little underwhelmed. We both thought that the 2 hour dam tour might have been better, but we didn’t have enough time for that.

Needless to say, it was somewhat of a downer coming back home to cold weather, and snow. Both my wife and I were looking for Vegas deals all week, and we will definitely be going back sometime.

On Wednesday, March 25, the first meeting of the Madison All.Net special interest group (SIG) was held at Herzing College. The All.Net SIG is all about discussing all things related to Microsoft .Net technologies in an open spaces style meeting. Instead of the lecture hall style room we traditionally use for the Madison .Net User Group meetings, we opted for a classroom style room due to the format of the meeting itself. Aside from a brief survey form I created to get an idea on what people were interested in, we had no set agenda.

Below are the results of the survey, which I took to get a general idea of what people were looking to get out of the group. Just because something didn’t get a lot of votes (i.e. Windows Embedded only got one vote, which was me) doesn’t mean people can’t come to a meeting to ask for help, share their code and participate.

After the survey, I talked about the Mix09 conference I attended last week. This was a two way discussion, with lots of good questions, and not a presentation (no power point at all!). We talked briefly about Silverlight 3, Blend 3 (Sketchflow), Expression Web 3 (Super Preview), and .Net RIA services. While we were enjoying some Pizza, we watched a bit of the Bill Buxton/Scott Guthrie keynote, and had a good laugh at Scott’s intro video.

After the Pizza break we started looking at the Entity Framework, and some ideas on a group project. I did a quick tally in my head of the technologies people were interested in, and Asp.Net MVC, ORM (EF, nHibernate, etc), and general architecture were the top 3. I sketched out a pretty lame diagram showing how we could create a project that allowed us to tackle the top 3 (and other) technologies.

The project I proposed was basically a typical 3 tier application consisting of a Asp.Net MVC front end, domain layer (business logic/objects), and a data access layer implemented using a variety of ORMs. The reason for working with multiple ORMs, is that everyone has different needs, wants and desires, and we’re trying to be as inclusive as possible. I think almost everybody has some type of standard they need to use at work, and in addition to pushing the boundaries of technology they be already familiar with, they also want to try new things, and see how things work when implemented with a different ORM.

In order to allow for the use of multiple ORMs, I suggested the use of a repository pattern, which in simple terms, is a in memory collection of domain objects. To implement, you define a set of interfaces in your domain (business layer), and then create concrete implementations of the interfaces for each ORM you wish to implement. This is quite a common approach in Domain Driven design, and in the Alt.Net space, however, it’s usually done to aid in the testability and maintainability of the code base.

The following is my best attempt to create a list of all the web sites and projects that I referenced during the discussion (in no particular order). It is important to note that everyone’s implementation and terminology is a little bit different.

• Jeff Palermo's Onion Architecture
• Code Camp Server – Asp.Net application used to manage code camps
• Foundations of Programming E-Book and Sample Application
• Sharp Architecture – “a solid architectural foundation for rapidly building maintainable web applications leveraging the ASP.NET MVC framework with NHibernate”
• ASP.NET MVC Storefront Starter Kit – It’s listed under sample applications halfway down the page

I don’t believe there was any final decision made on if or when we will start a group project, but I am excited to continue to talk about this. I already got one e-mail from someone who attended asking for examples which is why I included the list above.

Our next meeting should be around April 15th, but be sure to check the MadDotNet web site for the official date and time.

Even though I’m not actively developing in BizTalk these days, I still have a need to go in and do some support on an existing system a couple of times a year. Of course it takes me a little bit to get back into the BizTalk frame of mind. Today, I had to make a couple of changes to an orchestration and deploy. Part of this process involved un-enlisting several receive locations while I made this change.

When I re-enlisted the receive locations and went to check for problems, I noticed that all of my messages where not being processed due to there be no subscription setup for them. I knew that my orchestration should be subscribed to these messages, and thankfully BizTalk creates a suspended message instance that lists the context of the message at the time of the routing failure. I immediately noticed that none of my promoted properties were in the context, which would explain the routing issue.

It took me a while to figure out how to fix this, but in the end I noticed that the receive pipeline on my receive locations looked incorrect. Checking a staging server, documentation, and an XML copy of the bindings I exported before the change, I confirmed my suspicion. It seems that during the the deployment process and the un-enlist and re-enlist, some of my receive locations reverted to the default pass thru receive pipeline. After changing them back the XML receive pipeline, things are all good.

On Sunday, March 15th, I participated in the Harbor Athletic Club Dust the Rust Indoor Triathlon (sponsored by Endurance House). This was my first competitive event in the sport of Triathlon, and I had a great time, taking 2nd. There were about 14 total participants, so while it would have been nice to have some more competition, it did keep things moving smoothly.

The format of the event was a 10 minute swim, 30 minute bike and 15 minute run. You had to swim as many pool lengths, and run as many times around the indoor track as possible in the given time limit. The biking portion, which was done on the same Keiser M3 spinners I’ve been training on all off season, was based on how many miles the display showed after 30 minutes. Unfortunately, this isn’t very realistic, as the mileage shown is dependent on the how fast you could pedal, not on the amount of watts.

So while I was aware of this fact, I just didn’t feel like pedaling at 160+ RPM for 30 minutes. I’ve been training all season to push a harder gear at around 90 RPMs, so the high RPM game just wasn’t my thing. I made a suggestion that a more realistic measurement would be to use the average watts you are able to sustain over the 30 minute time frame. It’s not that I think this would have allowed me to do significantly better, but would be more representative of the actual biking event.

I also have some concern over the calibration of the bikes, both between the bikes at the club, and with the bikes I’ve been training on this off season. My baseline is usually around 90 RPM at gear 13 which produces approximately 230 watts (or so the display says). At the event, I was pushing gear 14 at 120 RPM producing 350-360 watts and it felt easier then the 230 watts I’m used to. So while my usual training bike might be off on the low end, these were definitly off on the high end. Maybe I’m too much of a stat junky?

However, the biking thing aside, I did have a really great time. This was partly do to how well I did on the swim and run portion of the event. I actually tied for 1st in the swim, completing 25 lengths or 625 yards in 10 minutes. This worked out to a 1:45 min/100m pace which is awesome for me. I’ve been working on 200m sets in training, and having a hard time maintaining that pace (after the first set), so keeping it for 625 yards is very satisfying. 625 yards is about 571 meters, so I definitely set a new personal best for the 500 meter distance. I feel as if the 1:45 min/100m pace is attainable for my triathlon in June as I have 12 weeks of training left.

I also did well in the run, completely 30 laps or 2.5 miles on the indoor track which is a 10mph average. Again, this was a personal best, although not a sustainable speed. I think I did the first mile in 5:30, which is the fastest I’ve run, albeit on a flat indoor track. Training with a 1% grade on the tread mill really paid off.

Personal Results (2nd place overall):

UPDATED: 4/25/2008 – See my new post of Partial SSL in Asp.Net MVC using the RequireSSL attribute from the MVC Futures Project

Tonight I was working on a small Asp.Net MVC project and was trying to add authorization and “require ssl” to specific pages using IIS. Of course you don’t have pages like you used to in Web Forms, so setting security and SSL on a per directory and per file basis doesn’t work like I’m used to.

The authorization requirement is actually pretty easy to handle once I approached the problem from a strictly MVC point of view. Using the Authorize attribute, which is included with Asp.Net MVC, I was able to pick and choose which controller actions I wanted to secure. In the code sample below I’m requiring the requestor to belong to the Users role.

[AcceptVerbs(HttpVerbs.Get), RequireSslFilter(Order=1), Authorize(Roles="Users",Order=2)]
public ActionResult ToServer()
{
   return View("ToServer");
}

When you need a little more control, you can implement a class that inherits from AuthorizeAttribute. Examples of when you might want to do this, would be if you wanted to change the authorized role at runtime, or not require any role (perhaps in your dev environment), or when you want to require SSL. In the above example you can see the RequiresSslFilter, which is a custom filter implemented as shown below which requires the use of SSL.

public class RequireSslFilter:AuthorizeAttribute
{
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
   if (httpContext.Request.IsLocal == false && httpContext.Request.IsSecureConnection == false)
   httpContext.Response.Redirect(httpContext.Request.Url.ToString().ToLower().Replace("http", "https"));

   return base.AuthorizeCore(httpContext);
}

}

In the code, I’m checking for if the request is local and secure, and redirecting to a secure version of the request. The check for IsLocal is useful for development scenarios. I added the Order parameter to the use of the RequiresSslFilter attribute to ensure that I check for the use of SSL before the check for the role. This helps ensure that credentials are only sent over SSL.

Tonight I was doing some load testing on an application I’m developing. Initially I was testing without SSL, but then needed to switch over to SSL, but hadn’t setup by development server with a cert. I jumped onto ssl4net (a free online certificate management site) and created a new cert for my server and proceeded to import it in IIS 7, but got the error “A specified login session does not exist. It may already have been terminated”.

I jumped around on Google for a bit and found this post by Omri Gazitt, and another post by FreakCode. The first talked about granting everyone permissions to the file that corresponds to the cert (on my computer the RSA certs are located at C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys). I remember doing something similar to this before, but it just didn’t seem right. The second post suggested marking the certificate as exportable when importing in IIS, and I had already done that so that wasn’t my problem either.

I decided to remove the cert, and try using the MMC Certificate snap-in to import the cert. I also gave it a friendly name from with-in the MMC. Going back to IIS and selecting this cert in the binding dialog no longer produced an error. I don’t know if it was how I imported it, or the friendly name, but it is/was too late to go back and play with it any more.

I was having some problems with file permissions, my web hosting provider and DasBlog. It seems to have been related to compiling and e-mailing the daily status report, so I've turned that off for now. Hopefully it will stay running.

I have been toying with the idea of hosting my stuff back at home like I used to back in the day. I was the first of my friends to get broadband, thanks in part to UW-Madison and my dad (paying the bill). Great thing about the UW-Madison DSL was that they let you host all the services you wanted to. At one point I was running a mail server on linux (can't remember which one), web, DNS, and a dedicated Unreal Tournament server.

I've been working on upgrading my home gear. I recently purchased a slew of UPS's (thanks to Circuit City going bye-bye), and while they won't protect against anything longer then probably 20 minutes, still good enough for my "mission critial" website ;). Also picked up two more WD Caviar Black HD's to create anothe Raid-1 array for my VM's. Also on the to-do list is to setup a pfSense firewall so I can have a properly segmented network between my internal services and external (DMZ).

The only thing I'm missing is my iSCSI array so I can setup clusterd hyper-v machnes with quick motion to avoid downtime, but again, we're not talking mission critial stuff here. I think I can afford 10-15 minutes of downtime each month while I patch all the VM's and the host machine.

I went to RDP into one of my local Hyper-V virtual machines this morning, only to find out I wasn’t able to connect. Browsing to the Hyper-V manager I saw that none of my VM’s were running. At first I couldn’t figure out why this was, until I remembered that my desktop machine was powered off this morning, indicating we had a brief power outage. The laptop, which obviously has a battery, was able to withstand the power outage, but the external hard drive, which requires external power was not. While I do have a UPS, it’s a piece of crap that never worked. Maybe now would be a good time to pick up another UPS on closeout from Circuit City, I’ll have to run that one past my manager.

I tried starting my VM’s, but most of them wouldn’t start, giving an error stating that the VM couldn’t start in it’s current state (which appeared to be saved). I tried to delete the saved state, and got an error stating that the saved state could not be deleted in the current state. The common thing between the VM’s that would start, and those that wouldn’t, was that the VM config files were also on the external hard drive. Browsing to the external hard drive, showed that the folder that contained the VM config files was empty (not a good sign). I checked the event log to see if I could get some more information, and 100’s of warnings indicating a problem with my external hard drive. I figured the best thing to do at this point was to shut down my laptop, power cycle the external hard drive and double check all connections.

After the reboot, the drive was functional (well almost) again, and there were no more warnings in the event log. While the VM config files were back where they were supposed to be, I still couldn’t start the VM’s. I also could not delete the VM config files from within Hyper-V manager. I went back to the config folder and went to Cut/Paste (move) the config files someplace else thinking I would just recreate the VM config. However, I couldn’t cut, move, delete or do anything other then browse (read) the files and folders.

Jumping back to Server Manager, I opened up Disk Management utility and saw that my external hard drive was listed as read only. I looked in just about every place I could think of, but could not find a way to make the disk read/write again. A Google search yielded no usable results, as it seems this is a pretty obscure problem. Aside from the legitimate answer of “does your removable media have a write protect switch”, all the other answers seemed to focus around viruses and other seemingly unrelated solutions.

Finally I decided to try my the only option that wasn’t grayed out for the read only disk in Disk Manger, and that was to take the disk offline, then bring it online again. Wow, that fixed it, the disk was now back in the standard read/write mode, and finally my VM’s would start. It appears as if the VM config file on at least one of the VM’s was corrupted, as I had to reselect my network adapters, but that was an easy fix.

If you are reading this, it means I’ve successfully updated to the latest version of DasBlog, version 2.2. I’m calling this the 1.1 version of my blog, with a couple of point releases scheduled in the near future focused on a new theme, proper support for uploading images, and code formatting.

I don’t even know what version of DasBlog I was running before this, so I wanted as clean an upgrade as possible. I decided to start with a completely clean install, then copy my posts over, diff the config files and see what happens. Since I run my blog in a virtual directory with a sub domain pointer, I created a new virtual directory to do testing, and then updated the sub domain pointer when everything was ready to go.

Here are the steps I took to upgade to DasBlog 2.2:

1. Download DasBlog 2.2 from the CodePlex Site. I chose the web-files.zip file.
2. Unzip the web-files.zip to a temp directory
3. Copy my content folder from my old blog to the dasblogce folder in the new temp folder. I actually backup my content folder daily from my hosting provider, so I already had this locally.
4. Leaving everything else the same for now, I zipped up the contents of the dasblogce folder and uploaded it to my hosting provider
5. Create a new sub folder on the root of my website called blog2
6. Extract the contents of the zip file I uploaded in step 4 to the blog2 sub folder.
7. Using WinMerge, diff the web.config file between the old and new site
8. Again, using WinMerge, diff the SiteConfig folder
9. Finally diff the theme I am using, re-adding support for
1. Google Analytics
2. OpenID
10. Test
11. Update blog.salvoz.com to point to the new folder
12. Final updates to configuration
13. Update backup routine to pull from the new folder

All in all it wasn’t too painful to do a clean update, and I’m glad I went that way. Total time start to finish was about 2.5 hours.

This week was a pretty good week for training, in that I achieved two milestones, all before even starting my formal training plan. I have to admit that I’ve been doing “training” for the last couple of months, where the rest of the tri-community are all doing cross training. I was doing cross training last fall until it started to take a toll on my legs (interior shin splints), and then switched over to biking, followed by swimming, and then decided, why not try running a triathlon. 

Anyway, about those two milestones I archived this week. First, I averaged over 230 watts (232 watts) for the first time on my two hour endurance ride. All of my winter training is done on a Keiser M3 stationary bike wearing my normal biking shoes. The workout consists of 120 minutes of tempo work, divided up between a base gear (~90 RPM to hit target wattage) for 40 minutes, 20 minutes of a higher gear, then 60 minutes of the base gear. The gearing really won’t mean much to anyone else, but I did 13, 16, and then 14. I was doing 13, 15, 13 for a 8 weeks, but switched up to 13,16,13 a couple of weeks ago, and this week was the first time I was able to push gear 14 for the full second half of the workout.

The second milestone, was a 1500m time trial in a pool, in which I broke the 30 minute mark, setting a new personal best at 29:26. When I first started swimming back in November I think, I was able to swim 1500m in around 38 minutes, so in about three months I’ve shaved off over 8 minutes. Now if only it would be as “easy” to shave another 8 minutes off. I think the biggest impact on my swimming has been improving my technique, although I do feel my swim endurance getting better, and I feel less out of breath.

I am really looking forward to starting my actual 16 week training plan next week, in preparation for the Capital View triathlon. I still have to work out the details of the plan, and am trying to decide between a couple of different “levels” as defined in the book I have. Some of the starting distances for the swim, and bike duration seem awfully low, but instead of stepping up a level, I could just try to increase the intensity. Most of the reading I have done indicates that higher intensity workouts pay greater dividends then lower intensity but longer workouts.

Given my 1500m time of 29:26, I figure I could have increased my pace for a 20 minute test by 10%, so my 100m pace would be 1:45. I will use this number to figure out my different training zones for swimming, and based on some training sets I’ve done in the past, this will be a very good pace for me to shoot for. At this point, I’m hoping to break the 25 minute mark in the pool by June, which should hopefully equate to a 30 minute open water swim, although I have nothing to base this on.

You can view my online training log at Buckeye Outdoors (yeah, I think it’s a weird name for a training log site as well).
