This document discusses object-oriented programming (OOP) concepts in C, specifically inheritance. It provides an example of inheriting data structures in C by using memory casting to access base class members from a derived structure. While this allows representing inheritance relationships, it lacks compiler protections and the developer must be careful, as incorrect memory access could lead to runtime errors. The document questions whether constructs like constructors and virtual functions available in C++ would be needed for C inheritance implementations and says the next slides will discuss this.
Virtual Functions support dynamic binding and object-oriented programming. A class that declares or inherits a virtual function is called a polymorphic class.
The presentation shows major features of the new C++ standard (language and the library). The full list of new things is very broad, so I've categorized them to be easier to understand.

Fun with Lambdas: C++14 Style (part 1)Sumant Tambe
If virtual functions in C++ imply design patterns, then C++ lambdas imply what? What does it really mean to have lambdas in C++? Frankly, I don't know but I've a hunch: It's BIG.
Just like virtual functions open doors to the OO paradigm, lambdas open doors to a different paradigm--the functional paradigm. This talk is not a praise of functional programming or some elusive lambda-based library. (Although, I'll mention one briefly that tops my list these days.) Instead, the goal is to have fun while working our way through some mind-bending examples of C++14 lambdas. Beware, your brain will hurt! Bring your laptop and code the examples right along because that may be the fastest way to answer the quiz.
Sometimes you see code that is perfectly OK according to the definition of the language, but which is flawed because it breaks too many established idioms and conventions. On the other hand, a solid piece of code is something that looks like it is written by an experienced person who cares about professionalism in programming.

Threads and Callbacks for Embedded PythonYi-Lung Tsai
Python is a great choice to be customized plug-ins for existing applications. Extending existing applications with Python program is also practical. For large systems, multi-thread programming is ubiquitous along with asynchronous programming, such as event routing. This presentation focuses on dealing with threads and callbacks while embedding Python in other applications.

One of the most popular programming language on the market is getting even better. With every iteration of C# we get more and more features that are meant to make our lives as developers a lot easier. Join me in this session to explore what's new in C# 8, as well as what we can expect in the near (and far) future of C#!
We'll talk about:
- News in C# 8
- Pattern Matching (incl. Record Types)
- Nullable Reference Types and How to Avoid Null Reference Exceptions
- How Async & Await is Improving
Welcome to the Program Your Destiny course. In this course, we will be learning the technology of personal transformation, neuroassociative conditioning (NAC) as pioneered by Tony Robbins. NAC is used to deprogram negative neuroassociations that are causing approach avoidance and instead reprogram yourself with positive neuroassociations that lead to being approach automatic. In doing so, you change your destiny, moving towards unlocking the hypersocial self within, the true self free from fear and operating from a place of personal power and love.
