What’s Driving the IOT trend• Costs are falling. The costs of the Internet of Things components such as

microchips, cloud services, GPS devices, accelerometers, connectivity, and other technologies have fallen and are now within reach for most organizations. In addition, processing power is becoming more affordable, and cloud computing services are increasingly available, vastly expanding the capability to crunch very large data sets.

• Connected device demand is accelerating. As more companies and consumers realize the value of connected things, the market is swelling into the billions and beyond.

Atlanta

What’s Driving the IOT trend• Device options are expanding. Everything from light bulbs and washing

machines to point-of-sale terminals is becoming connected, and that connectivity is also greatly improved, whether it’s wired, wireless, Wi-Fi, Bluetooth, cellular, or something else. And components are becoming more powerful—tiny microchips are now capable not only of connectivity but also of running much more advanced software than ever before.

• More machines are talking to each other. Machine-to-machine (M2M) solutions are going mainstream. Vodafone forecasts that 50 percent of companies will have adopted M2M communications technologies by 2020.

Atlanta

What’s Driving the IOT trend• Software is more advanced than ever. Today’s rich, dynamic business

software is putting high-level data analysis capabilities into the hands of companies around the globe.

• The economic benefits are enormous. The Internet of Things has the potential to create economic impact of $2.7 trillion to $6.2 trillion annually by 2025, according to McKinsey Global Institute.

• Microsoft’s Internet of Things White Paper

Windows Embedded – Manufacturing• M2M Connectivity – Connecting factory floor machines to each other and

the enterprise.• Analytics of factory floor data needed to improve processes• Increased interoperability with older devices (including PLCS, DCS)• Windows Embedded works at the real time speeds needed for factory

floors• Data input more effective with touch input for factory floor where safety

equipment is prevalent

What is SignalR?• ASP.NET SignalR is a library for ASP.NET developers that simplifies the

process of adding real-time web functionality to applications.• SignalR handles connection management automatically, and lets you

broadcast messages to all connected clients simultaneously, like a chat room.

• You can also send messages to specific clients. The connection between the client and server is persistent, unlike a classic HTTP connection, which is re-established for each communication.

Atlanta

Why SignalR?• Clients include:

– Javascript– C#– Android (SignalA) – IOS (Signalr-ObjC)

Atlanta

Transports• HTML 5 Transports

– WebSocket - WebSocket is the only transport that establishes a true persistent, two-way connection between client and server. However, WebSocket also has the most stringent requirements; it is fully supported only in the latest versions of Microsoft Internet Explorer, Google Chrome, and Mozilla Firefox, and only has a partial implementation in other browsers such as Opera and Safari.

Atlanta

Transports– Server Sent Events - Commonly used to send message updates or

continuous data streams to a browser client and designed to enhance native, cross-browser streaming through a JavaScript API called EventSource, through which a client requests a particular URL in order to receive an event stream. (if the browser supports Server Sent Events, which is basically all browsers except Internet Explorer.)

Atlanta

Transports• Comet Transports

– Forever Frame - (for Internet Explorer only). Forever Frame creates a hidden IFrame which makes a request to an endpoint on the server that does not complete. The server then continually sends script to the client which is immediately executed, providing a one-way realtime connection from server to client.

– AJAX long polling - Long polling does not create a persistent connection, but instead polls the server with a request that stays open until the server responds, at which point the connection closes, and a new connection is requested immediately.

C++ for .NET developersI will presenting C++ for .NET developers at the Windows User’s Group on October 6, 2014.

Synopsis - First; let’s take a look at the difference between native code and .NET native. Next, go over new C++ language features that are similar to our favorite in C#. Then, explore properly calling native code from managed code. Finally, look at passing workloads to graphics cards natively using C++ Amp.
