C++11 is being deployed and the shape of C++14 is becoming clear. This talk examines the foundations of C++. What is essential? What sets C++ apart from other languages? How do new and old features support (or distract from) design and programming relying on this essence?
I focus on the abstraction mechanisms (as opposed to the mapping to the machine): Classes and templates. Fundamentally, if you understand vector, you understand C++.
Type safety and resource safety are key design aims for a program. These aims must be met without limiting the range of applications and without imposing significant run-time or space overheads. I address issues of resource management (garbage collection is not an ideal answer and pointers should not be used as resource handles), generic programming (we must make it simpler and safer), compile-time computation (how and when?), and type safety (casts belongs in the lowest-level hardware interface). I will touch upon move semantics, exceptions, concepts, type aliases, and more. My aim is not so much to present novel features and technique, but to explore how C++’s feature set supports a new and more effective design and programming style.
I det sidste år er har vi lanceret flere ændringer til Dynamics AX 2012 R2, som blandt andet indeholder forbedret supply chain funktionalitet. Kom og oplev hvordan disse styrker AX; vi vil bl.a. give en demo som viser dig hvordan du får indsigt i dit nuværende og fremtidige warehouse space utilization, kigge på de nye muligheder for at analysere planlægningsresultatet samt den forbedrede CTP funktionalitet. Du vil endvidere få en lille smagsprøve på nyhederne til næste version.
Windows Azure Cloud Services is an awesome platform for developers to deliver applications in the cloud without needing to manage virtual machines. However, the abstraction that gives you this simplified deployment and scale, prevents you from attaching a Visual Studio Remote Debugger. Sometimes you need visibility into the execution of your production applications. What if you could replay the real production usage with the exact call sequence and variable values using the Visual Studio Debugger? What if you could collect production metrics that would help you identify performance bottlenecks and slow code? In this session, Eric Boyd will walk you through debugging and monitoring real-world Windows Azure applications. Eric will show you how to collect diagnostics like Event Logs, Perf Counters, IIS Logs, and even file-based logs from running Windows Azure compute instances. Next, Eric will also show you how to debug your production Windows Azure services using IntelliTrace's black box recording capabilities. Lastly, you will learn how to collect CLR-level diagnostics and performance metrics without instrumenting your code using tools like AppDynamics and New Relic. If you feel like Windows Azure Cloud Services are a black box when debugging issues and solving performance problems, you will leave this session feeling like Windows Azure is radically more transparent and easier to debug than the applications in your own data center.
