Software Adventure - new blog name

I decided to change name of this blog, because I am going to present not only C++ topics here. From today you can expect topics describing problems and features of following domains of software development:

C++ programming language features, problems, issues
C programming language features, problems, issues
Unix/Linux programming (ex. standard Linux C library, system calls etc.)
Embedded Linux programming (problems and solutions related to Embedded Software Development)
Software Development Design - Object Oriented Programming, Design Patterns etc.
Software Development Life Cycle
Sometimes I will also present some articles related to other programming languages like: Python, Java, JavaScript, HTML, CSS etc.

As you noticed range of topics in this blog has been significantly extended. It should this blog more interesting.

Blog's new layout

As you noticed this blog has new layout from today. I hope you like it. I think new layout looks better and more modern than previous one. Please, write you opinion about new layout in comments. If you have some ideas how to make this blog better, all ideas are welcomed. Enjoy new layout and blog articles.

QT - foreach algoriithm with const references performance improvement

Today I would like to show you optimal way of using foreach QT algorithm . I will show you why we should pass elements of foreach algorithm by const reference instead of passing them by value. Let me explain it on the below example: Output of this example is: In point I we are creating 3 objects of MyClass class and push them to myClasses QList element. In point II we are using QT foreach algorithm to invoke getValue() method for each object from myClasses list. As you can see on output text for that part of code we are invoking copy constructor before and destructor after invoking getValue() function. It is because we are passing each myClasses list element to foreach algorithm by value. Therefore we are copying that element at the beginning of foreach loop step and removing them (destructing) at the end. This is inefficient solution, especially when class of object being copied is big. It decreases performance. of our application. Solution for that i...

C++ in 2014 - Predictions

Today I would like to share with you interesting article about prediction of development C++ programming languages (and its well-known frameworks and libraries) in 2014. It is written by Jens Weller and I think it is very interesting for every C++ programmer and user. You can open this article by clicking on the image below: Enjoy!
