Each one of those principles solves a particular problem. 123. 7 Advanced C++ Concepts You Should Know 123. 7 Advanced C++ Concepts You Should Know So I have started updating myself with Modern C++ a while ago & since my post 21 new features of Modern C++ to use in your project & All about lambda function in C++ was popular I decided to write about advanced C++ concepts & idioms which I have learned from this wikibook & course. 124. Solving Producer/Consumer Problem of Concurrent Programming in Python 124. Solving Producer/Consumer Problem of Concurrent Programming in Python In "Concurrent Programming in Python is not what you think it is", I wrote about the notorious GIL in Python and did a simple experiment on existing concurrency mechanism in Python. Today, I'll describe another common scenario in concurrent programming, the Producer/Consumer problem, with Python. 125. How to Find the Stinky Parts of Your Code (Part IV) 125. How to Find the Stinky Parts of Your Code (Part IV) Are we done on code smells? Guess not. 126. Introduction to Object-Oriented Design Patterns 126. Introduction to Object-Oriented Design Patterns After hitting a certain level of experience & spending quite enough time in the industry, I have realised the importance of designing/architecting system & software. So I have started looking into system/software design & got to know nothing can better start than a Design Pattern. And the first thing I have done is googling "What is Design Pattern?" Hence got the idea of this article. 127. How to Decouple a Legacy System 127. How to Decouple a Legacy System An exercise improving legacy code 128. C++ Template: A Quick Review of C++11/14/17/20 Version 128. C++ Template: A Quick Review of C++11/14/17/20 Version I know, it’s been a while since the last time I published something newbies-friendly on my blog. The main reason is that most of my readers are either experienced devs or from C background having modest C++ encounter. But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.
