It covers functional programming concepts like immutability, recursion, and declarative programming. It then demonstrates how functional programming principles can be used in C# through techniques like Func and Action generics, LINQ queries, closures, currying, and parallelism using TPL and Rx. Resources for learning more about functional programming in C# and other languages are provided.
The document summarizes a talk given by Daisuke Maki on working with OpenAPI specifications, including slicing, dicing, and linting them. It discusses tools developed for the lestrrat-go/openapi library for safely parsing, mutating, traversing, linting, and generating code from OpenAPI specs in Go and other languages. The tools aim to prevent specification errors, provide consistency across operations, and make it easier for developers to work with OpenAPI.
Memory management in Python involves allocating, deallocating, and coordinating memory for processes. Python uses reference counting to manage objects, keeping track of references to each object and freeing memory when the reference count drops to zero. The user does not need to manually manage memory as allocation and de-allocation are fully automatic. Variables in Python act as object references, and memory is reclaimed by the garbage collector when objects are no longer referenced.
Visual Studio 2010 and .NET 4 provide new tools for parallel programming including Parallel LINQ (PLINQ) and the Task Parallel Library (TPL). PLINQ allows existing LINQ queries to run in parallel by partitioning and merging data across threads. The TPL simplifies writing multithreaded code through tasks that represent asynchronous and parallel operations. These new frameworks make it easier for developers to write scalable parallel code that takes advantage of multicore processors.
Python Programming - VI. Classes and ObjectsRanel Padon
This document discusses classes and objects in Python programming.

Multithreading and OOP,
Functional Design for Multithreaded programming
and how Multithreading does not mean always concurency but multicore paralelism.
Smart pointers help solve memory management issues like leaks by automatically freeing memory when an object goes out of scope. They support the RAII idiom where resource acquisition is tied to object lifetime. Common smart pointers include std::shared_ptr, std::unique_ptr, std::weak_ptr, which help avoid leaks from exceptions or cycles in object graphs. make_shared is preferable to separate allocation as it can allocate the object and control block together efficiently in one allocation.
The sole purpose of sharing these slides are to educate the beginners of IT and Computer Science/Engineering. Credits should go to the referred material and also CICRA campus, Colombo 4, Sri Lanka where I taught these in 2017.

Kinect is a multimedia sensor from Microsoft. It is shipped as the touch-free console for Xbox 360 video gaming platform. Kinect comprises an RGB Camera, a Depth Sensor (IR Emitter and Camera) and a Microphone Array. It produces a multi-stream video containing RGB, depth, skeleton, and audio streams.
Compared to common depth cameras (laser or Time-of-Flight), the cost of a Kinect is quite low as it uses a novel structured light diffraction and triangulation technology to estimate the depth. In addition, Kinect is equipped with special software to detect human figures and to produce its 20-joints skeletons.
Though Kinect was built for touch-free gaming, its cost effectiveness and human tracking features have proved useful in many indoor applications beyond gaming like robot navigation, surveillance, medical assistance and animation.
The new standard for C++ language has been signed in 2011. This new (extended) language, called C++11, has a number of new semantics (in terms of language constructs) and a number of new standard library support. The major language extensions are discussed in this presentation. The library will be taken up in a later presentation.
The document discusses function call optimization in C++. It provides examples of constructor, base class constructor, and get/set method calls in both debug and release builds. In release builds, the compiler fully optimizes constructor calls and inlines non-virtual functions like get/set methods to improve performance. Only virtual functions cannot be optimized as their call sequence depends on runtime type.
The document discusses different ways to define integer constants in C, including using integer literals, the #define preprocessor directive, enums, and the const qualifier. It provides a table comparing how each option is handled by the C preprocessor, compiler, and debugger. Code examples are given to illustrate the behavior. The key points are that integer literals are replaced directly, #define symbols are replaced textually, enums and const ints create symbols but const ints allow address operations in both the compiler and debugger.
The document discusses the key components of the Standard Template Library (STL) in C++, including containers, iterators, and algorithms. It explains that STL containers manage collections of objects, iterators allow traversing container elements, and algorithms perform operations on elements using iterators. The main STL containers like vector, list, deque, set, and map are introduced along with their basic functionality. Iterators provide a common interface for traversing container elements. Algorithms operate on elements through iterators but are independent of container implementations.
The document discusses object lifetime in C/C++. It covers the fundamentals of object lifetime including construction, use, and destruction. It also describes the different types of objects - static objects which are compiler-managed and have lifetime from program startup to termination, automatic objects which are stack-based and destroyed when they go out of scope, and dynamic objects which are user-managed and allocated on the free store.

An object has ValueSemantics when it can be treated as a single value. In C++ this means implementing a copy constructor and an assignment operator in such a way that when a new or existing instance is set equal to some other instance the new instance will be equivalent to the old one without acting as an alias to it. In computing , a first-class object (also -value , -entity , -citizen ), in the context of a particular programming language , is an entity which can be used in programs without restriction (when compared to other kinds of objects in the same language). Depending on the language, this can imply: being expressible as an anonymous literal value being storable in variables being storable in data structures having an intrinsic identity (independent of any given name) being comparable for equality with other entities being passable as a parameter to a procedure/function being returnable as the result of a procedure/function being constructable at runtime For example, in C , it is not possible to create new functions at runtime (however, see discussion ), whereas other kinds of object can be created at runtime. So functions in C are not first-class objects; sometimes they are called " second-class objects ". Similarly, strings are not first class objects in Fortran as it is not possible to assign them to variables, whereas numbers can be so assigned.

Source: cv-qualified type : http://www.embedded.com/showArticle.jhtml?articleID=9900322 A cv-qualified type has the form " cv T " where, cv is a sequence of cv-qualifiers ( const and volatile ) and T is a type (without cv-qualifiers). The sequence cv can be empty, just const by itself, just volatile by itself, or const volatile (in either order). For any two sequences of cv-qualifiers cv1 and cv2 , we say that cv1 has the same or greater cv-qualification than cv2 , and write cv1 >= cv2 , if every cv-qualifier in cv2 also appears in cv1 . If cv1 >= cv2 is false, then we say that cv1 has less cv-qualification than cv2 . “ A Proposal to Add General Purpose Smart Pointers to the Library Technical Report ”, 27-Mar-03. http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2003/n1450.html

As a result, this version of the proposal requires use_count() == 0 to hold for all empty pointers, and the code sample will reliably print "std::bad_weak_ptr".” – What does it mean?
