Object Oriented Programming Concepts
Object Oriented Programming Conceptsthinkphp The document discusses key concepts in object-oriented programming including objects, classes, messages, and requirements for object-oriented languages. An object is a bundle of related variables and methods that can model real-world things. A class defines common variables and methods for objects of a certain kind. Objects communicate by sending messages to each other specifying a method name and parameters. For a language to be object-oriented, it must support encapsulation, inheritance, and dynamic binding.
Types of Compilers
Types of CompilersHemant Chetwani This document provides an overview of different types of compilers. It discusses incremental compilers, cross compilers, load & go compilers, threaded code compilers, stage compilers, just-in-time (JIT) compilers, parallelizing compilers, one pass compilers, and multi pass compilers. For each type of compiler, it briefly describes what it is and how it works. The key information covered includes that incremental compilers only recompile modified source code, cross compilers produce target code for a different machine, JIT compilers compile bytecode to native machine code just before execution, and multi pass compilers perform multiple scans of the source code to complete compilation tasks.
Clean Code: Chapter 3 Function
Clean Code: Chapter 3 FunctionKent Huang This document discusses principles for writing clean code in functions. It recommends that functions should be small, do one thing, have descriptive names, and avoid side effects. Functions with many arguments or switch statements are harder to understand. Exceptions should be used instead of return codes to indicate errors. Overall, following best practices for functions helps produce code that is easy to read and maintain.
Functions and modules in python
Functions and modules in pythonKarin Lagesen The document discusses functions, modules, and how to modularize Python programs. It provides examples of defining functions, using parameters, returning values, and function scope. It also discusses creating modules, importing modules, and the difference between running a Python file as a module versus running it as the main script using the __name__ == "__main__" check. The key points are that functions help break programs into reusable and readable components, modules further help organize code, and the __name__ check allows code to run differently depending on how it is imported or run directly.

PHP
PHPsometech The document provides an introduction to PHP basics including:
- PHP code is embedded in HTML using tags and the server executes the PHP code and substitutes output into the HTML page.
- PHP supports variables, data types, operators, control structures like if/else statements and loops. Useful built-in functions allow working with forms, cookies, files, time and date.
- Server-side programming alternatives like CGI, ASP, Java Servlets, and PHP are discussed. PHP was created in 1995 and is now widely used as a free, open-source scripting language for server-side web development.
Variadic functions
Variadic functionsKoganti Ravikumar Variadic functions allow a function to take a variable number of arguments. They are declared with an ellipsis after the last named parameter. The stdarg.h header provides macros for accessing the variable arguments: va_start initializes argument parsing, va_arg returns the next argument of a given type, and va_end cleans up. An example sums all integer arguments by iterating with va_arg, illustrating how variadic functions work.

Clean Code I - Best Practices
Clean Code I - Best PracticesTheo Jungeblut All 3 Clean Code presentations provide great value by themselves, but taken together are designed to offer a holistic approach to successful software creation. This first session creates the foundation for the 2nd and 3rd Clean Code presentation on Dependency Injection, as it explains expected base knowledge. Why writing Clean Code makes us more efficient Over the lifetime of a product, maintaining the product is actually one - if not the most - expensive area(s) of the overall product costs.
Writing clean code can significantly lower these costs. However, writing clean code also makes you more efficient during the initial development time and results in more stable code. You will be presented design patterns and best practices which will make you write better and more easily maintainable code, seeing code in a holistic way.
You will learn how to apply them by using an existing implementation as the starting point of the presentation. Finally, patterns & practices benefits are explained. This presentation is based on C# and Visual Studio 2012. However, the demonstrated patterns and practice can be applied to every other programming language too.
Note: Moving forwards this presentation will be updated with the latest version of the slides for the last event I did the presentation instead of creating new separate slide decks here on SlideShare.

Deming_Recognition_Expanded_With_Notes.pptx
Deming_Recognition_Expanded_With_Notes.pptxRaulAmavisca This presentation explores W. Edwards Deming’s philosophy of recognition, emphasizing a systems-oriented, intrinsic, and respectful approach to motivating people and improving quality.
Rather than promoting conventional rewards like bonuses, rankings, or employee-of-the-month awards, Deming believed that true recognition emerges from creating a culture where people are empowered, respected, and involved in continual improvement. The presentation deconstructs this philosophy across key themes:
System over the Individual: Performance should be understood within the context of the system, not blamed on individuals.
Intrinsic Motivation: The most powerful form of recognition is enabling people to take pride in their work.
Respect and Involvement: Recognition includes actively listening to employees and involving them in decisions.
Continual Improvement: Contributions to systemic improvement are the highest form of recognition.
Rejection of Traditional Rewards: Deming opposed fear-based systems like rankings and incentives.

MNC - Simpatico PR B2B PR agency case study 0625.pdfSimpatico PR How to build your B2B PR profile rapidly.
Some businesses – not many – but a few, grow their businesses without publicity. But then moment comes when PR is essential. Independent media agency MNC was silent for thirty years then achieved 20+ media articles in four months – how?
Our mission
Our B2B PR agency brief was to announce and promote MNC’s positioning and support business growth. To do this we needed to achieve an initial burst of exposure and then keep that coming across a range of media including – critically – vertical trades.
When a business has zero media profile and no relationships with the press the challenge boils down to credibility – as one journalist put it “why should we write about an agency nobody has heard of?”
Here’s how:
We identified a series of initial messages that were genuinely topical and credible for MNC to own.
- Indie agencies Vs. Holdco’s
- The fusion of media and venture funding
- Marketing shibboleths that need a rethink
- Why indies will win talent
We pitched creatively to media, mixing topicality, trend analysis and humanising complex issues.
We built relationships using podcasts and other media formats to build a dialogue between MNC’s talented team and journalists.
We looked at what MNC’s prospects were interested in and converted POVs to work in vertical media.
We became an extension of their team – their wins are ours.
We pushed hard and kept momentum going – creating a full pipeline of content to leverage.
Results
The initial outcomes
- Growth in new prospect opportunities
- Supporting client conversions
- Massive up-tick in social exposure and audience reach
- All media targets reached – vertical out-reach growing
