Windows Server 2012 : Access virtually anywhere, from any device (part 2) - Unified remote access - Deploying remote access
To see unified remote access at work, let’s walk through the initial steps of deploying a DirectAccess solution. Although we’ve used the UI for performing the steps described below, you can also use Windows PowerShell. You can also deploy the Remote Access role on a Windows Server Core installation of Windows Server 2012.
Windows Server 2012 : Access virtually anywhere, from any device (part 1) - Unified remote access - Simplified DirectAccess
If remote client devices can be always connected, users can work more productively. Devices that are always connected are also more easily managed, which helps improve compliance and reduce support costs
SQL Server 2012 : Locking and Concurrency (part 6) - THE DANGERS OF CONCURRENCY - Double Reads
Double reads can occur when scanning data while using the default read committed isolation level, covered later in this chapter. During a period of concurrent activity, it is possible for one query to perform a range scan on a table and, as it is scanning, a second transaction can come in and move a row, thus causing it to be read twice.
SQL Server 2012 : Locking and Concurrency (part 5) - THE DANGERS OF CONCURRENCY - Phantom Reads
Phantom reads occur when a row is inserted into or deleted from a range of data by one transaction that is being read by another set of data. Recall the earlier work queue scenario. Suppose a user reads the work queue searching for new work items and gets back 10 records.
SQL Server 2012 : Locking and Concurrency (part 4) - THE DANGERS OF CONCURRENCY - Dirty Reads
A non-repeatable read is one in which data read twice inside the same transaction cannot be guaranteed to contain the same value. Depending on the isolation level, another transaction could have nipped in and updated the value between the two reads.
SQL Server 2012 : Locking and Concurrency (part 3) - THE DANGERS OF CONCURRENCY - Dirty Reads
A dirty read takes no notice of any lock taken by another process. The read is officially “dirty” when it reads data that is uncommitted. This can become problematic if the uncommitted transaction fails or for some other reason is rolled back.
SQL Server 2012 : Locking and Concurrency (part 2) - THE DANGERS OF CONCURRENCY - Lost Updates
A lost update occurs when two processes read the same data and then try to update the data with a different value. Consider a scenario in which you and your partner have the romantic notion of a joint bank account.
SQL Server 2012 : Locking and Concurrency (part 1) - TRANSACTIONS, DATABASE TRANSACTIONS
Having looked at the ACID principles in the context of a bank transaction in the preceding section, this section examines how these four principles relate to your database environment, which you need to protect with just as much care as the bank affords to your monetary transactions.
Microsoft Exchange Server 2013 : Site mailboxes (part 2) - The life cycle of site mailboxes, Site mailbox provisioning policy
Unique among Exchange mailbox types, you cannot create a site mailbox through EAC. Instead, you create a site mailbox as an app on a SharePoint team site. A site mailbox is treated like any other app such as a list that forms part of the functionality offered to team members.
Microsoft Exchange Server 2013 : Site mailboxes (part 1) - How site mailboxes work - Synchronization between Exchange and SharePoint
Exchange synchronizes with SharePoint by using the SharePoint REST API to fetch the metadata used to display information about documents stored in the site mailbox, including document title, author, last modified date, checked-out status, and the user who last modified the item.
Getting started with SharePoint 2013 sites : Changing the navigation tree view settings - Change tree view settings
Depending on the purpose of your SharePoint 2013 site, you might want to modify the default navigation. Normally, SharePoint sites provide a Quick Launch bar for internal navigation and a Top Link bar that inherits from the parent site of the current site.
Getting started with SharePoint 2013 sites : Changing the look and feel of a site
The chances are good that when you start to use your SharePoint site, you will want to customize a few things to meet the specific needs of your team. Fortunately, SharePoint 2013 supports a number of out-of-the-box formatting options
Getting started with SharePoint 2013 sites : Locating content on a site, Changing your site’s title, description, and logo
If you are the owner of a SharePoint 2013 team site, there are two primary areas of the site that you will commonly access while maintaining the site: the site contents and the site settings.
Getting started with SharePoint 2013 sites : Creating a SharePoint site from a template - Create a SharePoint team site
SharePoint 2013 site administrators have a lot of latitude with regard to how they can create a site. They can choose to create a blank site and add different components to it, or they can employ a site template to assist them in creating some of the more common elements of the site.
Getting started with SharePoint 2013 sites : Understanding sites - Access a SharePoint site
Each site has a site administrator (or two) assigned to it. The site administrator’s duties can include granting access to the site, creating lists and libraries, and creating additional sites, to name a few.
Windows Server 2012 : Deploying and configuring Hyper-V hosts (part 6) - Configuring Hyper-V hosts - Creating virtual switches
If you select External as the connection type, you must assign a physical network adapter on the host to the new switch. In that case, you also have the option of allowing the management operating system on the host to share the selected network adapter.
Windows Server 2012 : Deploying and configuring Hyper-V hosts (part 5) - Configuring Hyper-V hosts - Configuring virtual machine storage
Everyone knows that it’s better to prevent problems from happening than to try and deal with things after they go wrong. That’s why it’s important to make sure you configure your default Hyper-V storage locations appropriately before you start creating new virtual machines on a Hyper-V host or importing existing virtual machines onto the host.
Windows Server 2012 : Deploying and configuring Hyper-V hosts (part 4) - Installing the Hyper-V role
If you are using Server Manager to install the Hyper-V role on a remote server, you might want to select the Hyper-V Module For Windows PowerShell on the Features page of the Add Roles And Features Wizard to install this module locally on the server.
Windows Server 2012 : Deploying and configuring Hyper-V hosts (part 3) - Planning Hyper-V deployment - Security, Disaster recovery
It’s important to consider the security of your Hyper-V hosts as you prepare your host deployment plan. To begin with, you should apply the same principles, processes, and practices for securing Hyper-V hosts that you would apply to any other Windows Server components within your environment.
Windows Server 2012 : Deploying and configuring Hyper-V hosts (part 2) - Planning Hyper-V deployment - Storage, Management
Different organizations have different requirements and different budgets for their IT operations, and Windows Server 2012 provides a wide range of physical storage options for Hyper-V hosts.
Windows Server 2012 : Deploying and configuring Hyper-V hosts (part 1) - Planning Hyper-V deployment - Hardware, Editions, Networking
A key hardware requirement for a Hyper-V host is that the underlying host system support hardware-assisted virtualization such as Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technologies.
Windows Phone 8 : Audio Streaming Agents (part 2) - Using a MediaStreamSource to Play Back an Assembly Resource
The built-in streaming and decoding system on the phone only supports playback of local audio files when they are located in isolated storage. This section looks at enabling the direct playback of audio files located within an app assembly.
Windows Phone 8 : Audio Streaming Agents (part 1)
Audio streaming agents allow you to customize how audio files are downloaded and decoded by your app, and they enable you to support live streaming scenarios not natively supported by the phone.
Windows Phone 8 : AudioPlayerAgent Sample (part 4) - Controlling Background Audio from Your Foreground App - Monitoring Playback Progress
The viewmodel contains a Position property that reflects the progress of the current AudioTrack. Because the BackgroundAudioPlayer does not have facility to monitor the progress of a track directly, the viewmodel uses a Timer to periodically raise a property changed event for the Position property.
Windows Phone 8 : AudioPlayerAgent Sample (part 3) - Controlling Background Audio from Your Foreground App - MainPageViewModel
The MainPageViewModel class constructor accepts an IBackgroundAudioPlayer as well as an IIsolatedStorageUtility instance (see Listing 1). A subscription to the PlayStateChanged event of the background audio player allows the viewmodel to update various properties whenever the play state changes.
Windows Phone 8 : AudioPlayerAgent Sample (part 2) - AudioPlayerAgent Virtual Methods
Whereas the OnPlayStateChanged method is used to respond to playback state changes, the OnError method is called when an error occurs during playback, and not OnPlayStateChanged.
Windows Phone 8 : AudioPlayerAgent Sample (part 1)
The custom audio player agent for this section includes a simple playlist, which includes both locally stored and remote audio files. The class is called BackgroundAudioPlayerAgent, and it is located in the WPUnleashed.BackgroundAudio project, within the BackgroundAudio solution in the downloadable sample code.
Windows Phone 8 : Coordinating Background Audio Playback (part 2) - Representing Audio Files with the AudioTrack Class, Creating a Custom Audio Player Agent
The AudioTrack class includes information about the location of an audio file, as well as track metadata, such as the track’s title. Table 3 describes each of the AudioTrack properties.
Windows Phone 8 : Coordinating Background Audio Playback (part 1) - Background Audio Player
The behavior of the BackgroundAudioPlayer changes depending on whether it is being used in your foreground app or from an AudioPlayerAgent. When the BackgroundAudioPlayer is used in your foreground app, all calls are relayed to your AudioPlayerAgent.
Microsoft Exchange Server 2013 : Site mailboxes (part 3) - The life cycle of site mailboxes, Site mailbox provisioning policy
Unique among Exchange mailbox types, you cannot create a site mailbox through EAC. Instead, you create a site mailbox as an app on a SharePoint team site. A site mailbox is treated like any other app such as a list that forms part of the functionality offered to team members.
