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.

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.

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.

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 developers
I 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.
