Quicken Loans TechCon 2018
September 20th at Cobb Center in Detroit I will be presenting:
Alternative Device Interfaces and Machine Learning
Abstract
In this presentation, we will look at the how users interface with machines without the use of touch. These different types of interaction have their benefits and pitfalls. To showcase the power of these user interactions we will explore: Voice commands with mobile applications, Speech Recognition, and Computer Vision. After this presentation, attendees will have the knowledge to create applications that can utilize voice, video, and machine learning.
Description
Users use voice (Alexa, Cortana, Google Now) or video as a mode of interaction with applications. More than a fad, this is a natural interface for users and is becoming more and more common with the ever-decreasing size of hardware.
Different types of interaction have their benefits and pitfalls. To showcase the power of these user interactions we will explore: Voice commands with two app types: UWP and Xamarin Forms (iOS and Android). Speech Recognition with Cognitive Services: Verifying the speaker with Speaker Recognition API. Computer Vision with Cognitive Services: Verifying a user with Face API.
By utilizing UWP, Xamarin, and Cognitive services; a device with the ultimate in customization for user interactions will be created. Come and see how!

- Enable IoT with Edge Computing and Machine Learning
- Virtual Reality and IoT – Interacting with the changing world
Enable IoT with Edge Computing and Machine Learning
Being able to run compute cycles on local hardware is a practice predating silicon circuits. Mobile and Web technology has pushed computation away from local hardware and onto remote servers. As prices in the cloud have decreased, more and more of the remote servers have moved there. This technology cycle is coming full circle with pushing the computation that would be done in the cloud down to the client. The catalyst for the cycle completing is latency and cost. Running computations on local hardware softens the load in the cloud and reduces overall cost and architectural complexity.
The difference now is how the computational logic is sent to the device. As of now, we rely on app stores and browsers to deliver the logic the client will use. Delivery mechanisms are evolving into writing code once and having the ability to run that logic in the cloud and push that logic to the client through your application and have that logic run on the device. In this presentation, we will look at how to accomplish this with existing Azure technologies and how to prepare for upcoming technologies to run these workloads.
Virtual Reality and IoT – Interacting with the changing world
Using IoT Devices, powered by Windows 10 IoT and Raspbian, we can collect data from the world surrounding us. That data can be used to create interactive environments for mixed reality, augmented reality, or virtual reality. To move the captured data from the devices to the interactive environment, the data will travel through Microsoft’s Azure. First it will be ingested through the Azure IoT Hub which provides the security, bi-directional communication, and input rates needed for the solution. We will move the data directly from the IoT Hub to an Azure Service Bus Topic. The Topic allows for data to be sent to every Subscription listening for the data that was input. Azure Web Apps subscribe to the Topics and forward the data through a SignalR Hub that forwards the data to a client. For this demo, the client is a Unity Application that creates a Virtual Reality simulation showcasing that data.
Once finished with this introduction to these technologies, utilizing each component of this technology stack should be approachable. Before seeing the pieces come together, the technologies used in this demonstration may not seem useful to a developer. When combined, they create a powerful tool to share nearly unlimited amounts of incoming data across multiple channels.
Elastic Search – “All shards failed” on pagination
If you are trying to page past the first 10000 documents in an Elasticsearch index and have not set the max_result_window setting for that index then you may receive one of the two following errors:
-
All shards failed
-
Result window is too large, from + size must be less than or equal to: [10000] but was [*].
To resolve this the max_result_window setting must be set for the index that is being paged through. Using CURL or the Kibana dev console and make a PUT request to update the setting.
PUT {MY_INDEX}/_settings"
{
"index" : { "max_result_window" : {MAX_VALUE}}
}Replacing MY_INDEX with the index you wish to update the settings to and replacing MAX_VALUE with the maximum value for the result window. For the current project it was set to 50,000,000.

Hosting a permanent redirect in Azure
WordPress charges for each domain attached to a blog. That is a bit much when you consider .net, .org, .whatever domains that are used on top of the .com domain most use. To get the use out of a single domain, a permanent redirect can be used. Since Azure has a fixed price, invariant of how many domains you host there; it can be used for the permanent redirect.
Prerequisites
To complete this tutorial:
- Create an App Service app, or use an app that you created for another tutorial.
- Purchase a domain name and make sure you have access to the DNS registry for your domain provider (such as GoDaddy).
For example, to add DNS entries for
contoso.comandwww.contoso.com, you must be able to configure the DNS settings for thecontoso.comroot domain.Note
If you don’t have an existing domain name, consider purchasing a domain using the Azure portal.
Prepare the app
To map a custom DNS name to a web app, the web app’s App Service plan must be a paid tier (Shared, Basic, Standard, or Premium). In this step, you make sure that the App Service app is in the supported pricing tier.
Note
App Service Free and Shared (preview) hosting plans are base tiers that run on the same Azure VM as other App Service apps. Some apps may belong to other customers. These tiers are intended to be used only for development and testing purposes.
Sign in to Azure
Open the Azure portal and sign in with your Azure account.
Navigate to the app in the Azure portal
From the left menu, select App Services, and then select the name of the app.
You see the management page of the App Service app.
Check the pricing tier
In the left navigation of the app page, scroll to the Settings section and select Scale up (App Service plan).
The app’s current tier is highlighted by a blue border. Check to make sure that the app is not in the F1 tier. Custom DNS is not supported in the F1tier.
If the App Service plan is not in the F1 tier, close the Scale up page and skip to Map a CNAME record.
Scale up the App Service plan
Select any of the non-free tiers (D1, B1, B2, B3, or any tier in the Production category). For additional options, click See additional options.
Click Apply.
When you see the following notification, the scale operation is complete.
Map your domain
You can use either a CNAME record or an A record to map a custom DNS name to App Service. Follow the respective steps:
Note
You should use CNAME records for all custom DNS names except root domains (for example, contoso.com). For root domains, use A records.
Map a CNAME record
In the tutorial example, you add a CNAME record for the www subdomain (for example, www.contoso.com).
Access DNS records with domain provider
Note
You can use Azure DNS to configure a custom DNS name for your Azure Web Apps. For more information, see Use Azure DNS to provide custom domain settings for an Azure service.
Sign in to the website of your domain provider.
Find the page for managing DNS records. Every domain provider has its own DNS records interface, so consult the provider’s documentation. Look for areas of the site labeled Domain Name, DNS, or Name Server Management.
Often, you can find the DNS records page by viewing your account information, and then looking for a link such as My domains. Go to that page and then look for a link that is named something like Zone file, DNS Records, or Advanced configuration.
The following screenshot is an example of a DNS records page:
In the example screenshot, you select Add to create a record. Some providers have different links to add different record types. Again, consult the provider’s documentation.
Note
For certain providers, such as GoDaddy, changes to DNS records don’t become effective until you select a separate Save Changes link.
Create the CNAME record
Add a CNAME record to map a subdomain to the app’s default hostname (<app_name>.azurewebsites.net, where <app_name> is the name of your app).
For the www.contoso.com domain example, add a CNAME record that maps the name www to <app_name>.azurewebsites.net.
After you add the CNAME, the DNS records page looks like the following example:
Enable the CNAME record mapping in Azure
In the left navigation of the app page in the Azure portal, select Custom domains.
In the Custom domains page of the app, add the fully qualified custom DNS name (www.contoso.com) to the list.
Select the + icon next to Add hostname.
Type the fully qualified domain name that you added a CNAME record for, such as www.contoso.com.
Select Validate.
The Add hostname page is shown.
Make sure that Hostname record type is set to CNAME (www.example.com or any subdomain).
Select Add hostname.
It might take some time for the new hostname to be reflected in the app’s Custom domains page. Try refreshing the browser to update the data.
Note
To add an SSL binding, see Bind an existing custom SSL certificate to Azure Web Apps.
If you missed a step or made a typo somewhere earlier, you see a verification error at the bottom of the page.
Map an A record
In the tutorial example, you add an A record for the root domain (for example, contoso.com).
Copy the app’s IP address
To map an A record, you need the app’s external IP address. You can find this IP address in the app’s Custom domains page in the Azure portal.
In the left navigation of the app page in the Azure portal, select Custom domains.
In the Custom domains page, copy the app’s IP address.
Access DNS records with domain provider
Note
You can use Azure DNS to configure a custom DNS name for your Azure Web Apps. For more information, see Use Azure DNS to provide custom domain settings for an Azure service.
Sign in to the website of your domain provider.
Find the page for managing DNS records. Every domain provider has its own DNS records interface, so consult the provider’s documentation. Look for areas of the site labeled Domain Name, DNS, or Name Server Management.
Often, you can find the DNS records page by viewing your account information, and then looking for a link such as My domains. Go to that page and then look for a link that is named something like Zone file, DNS Records, or Advanced configuration.
The following screenshot is an example of a DNS records page:
In the example screenshot, you select Add to create a record. Some providers have different links to add different record types. Again, consult the provider’s documentation.
Note
For certain providers, such as GoDaddy, changes to DNS records don’t become effective until you select a separate Save Changes link.
Create the A record
To map an A record to an app, App Service requires two DNS records:
- An A record to map to the app’s IP address.
- A TXT record to map to the app’s default hostname
<app_name>.azurewebsites.net. App Service uses this record only at configuration time, to verify that you own the custom domain. After your custom domain is validated and configured in App Service, you can delete this TXT record.
For the contoso.com domain example, create the A and TXT records according to the following table (@ typically represents the root domain).
| Record type | Host | Value |
|---|---|---|
| A | @ |
IP address from Copy the app’s IP address |
| TXT | @ |
<app_name>.azurewebsites.net |
When the records are added, the DNS records page looks like the following example:
Enable the A record mapping in the app
Back in the app’s Custom domains page in the Azure portal, add the fully qualified custom DNS name (for example, contoso.com) to the list.
Select the + icon next to Add hostname.
Type the fully qualified domain name that you configured the A record for, such as contoso.com.
Select Validate.
The Add hostname page is shown.
Make sure that Hostname record type is set to A record (example.com).
Select Add hostname.
It might take some time for the new hostname to be reflected in the app’s Custom domains page. Try refreshing the browser to update the data.
Note
To add an SSL binding, see Bind an existing custom SSL certificate to Azure Web Apps.
If you missed a step or made a typo somewhere earlier, you see a verification error at the bottom of the page.
Map a wildcard domain
In the tutorial example, you map a wildcard DNS name (for example, *.contoso.com) to the App Service app by adding a CNAME record.
Access DNS records with domain provider
Note
You can use Azure DNS to configure a custom DNS name for your Azure Web Apps. For more information, see Use Azure DNS to provide custom domain settings for an Azure service.
Sign in to the website of your domain provider.
Find the page for managing DNS records. Every domain provider has its own DNS records interface, so consult the provider’s documentation. Look for areas of the site labeled Domain Name, DNS, or Name Server Management.
Often, you can find the DNS records page by viewing your account information, and then looking for a link such as My domains. Go to that page and then look for a link that is named something like Zone file, DNS Records, or Advanced configuration.
The following screenshot is an example of a DNS records page:
In the example screenshot, you select Add to create a record. Some providers have different links to add different record types. Again, consult the provider’s documentation.
Note
For certain providers, such as GoDaddy, changes to DNS records don’t become effective until you select a separate Save Changes link.
Create the CNAME record
Add a CNAME record to map a wildcard name to the app’s default hostname (<app_name>.azurewebsites.net).
For the *.contoso.com domain example, the CNAME record will map the name * to <app_name>.azurewebsites.net.
When the CNAME is added, the DNS records page looks like the following example:
Enable the CNAME record mapping in the app
You can now add any subdomain that matches the wildcard name to the app (for example, sub1.contoso.com and sub2.contoso.com match *.contoso.com).
In the left navigation of the app page in the Azure portal, select Custom domains.
Select the + icon next to Add hostname.
Type a fully qualified domain name that matches the wildcard domain (for example, sub1.contoso.com), and then select Validate.
The Add hostname button is activated.
Make sure that Hostname record type is set to CNAME record (www.example.com or any subdomain).
Select Add hostname.
It might take some time for the new hostname to be reflected in the app’s Custom domains page. Try refreshing the browser to update the data.
Select the + icon again to add another hostname that matches the wildcard domain. For example, add sub2.contoso.com.
