There is a powerful and simple concept in programming that is widely underused: Immutability
Basically, an object is immutable if its state doesn’t change once the object has been created. Consequently, a class is immutable if its instances are immutable. Continue reading “Domain Driven Design, Immutability and C++.”
As C++ developer if you have already build a C# or a java project you could be surprised by the speed of the build compared to C++. For some C++ projects it could take few minutes and for others, it could take many hours. It depends on the project size.
And even if the compilation phase is parallelized by using the cores available, the build still take too long compared to the other languages. Here are some reasons from this good stack overflow answer: Continue reading “The Importance of C++ Distributed Build Systems”
Back in March 2005 when herb Sutter published its famous article “The free lunch is over” and predicted a Concurrent Programming Revolution as big as Object-Oriented Revolution. And here’s a short explanation from the article about the prediction motivation : Continue reading “Is the Free Lunch Over? Revisiting Herb Sutter Prediction”
How many times do you read a reflexion concerning C++ like this one:
C++ is a difficult language even for experienced C++ developers. Even for the simplest algorithms you have to explain many of the language subtleties. Consider a Hello World example: Continue reading “Unleashing C++ Power: Richness in Low-Level Code”
Have you already seen a basketball or a soccer player plays a simple yet effective game to such a point that you say: Why couldn’t everybody play like him, he uses only easy techniques?
And as C++ programmer I had the same remark when exploring the John Carmack source code. It’s so simple, we wonder why we can ‘t develop like him.
Let’s explore some Doom3 source code choices and try to understand why the code even if it’s simple, it’s very efficient.
On November 23, 2011 id Software maintained the tradition and it released the source code of their previous engine. This source code was reviewed by many developers, here’s as an example of Doom3 feedback from fabien (orginal source): Continue reading “John Carmack: A C++ Programming Legend”
When the processes running on your machine attempt to allocate more memory than your system has available, the kernel begins to swap memory pages to and from the disk. This is done in order to free up sufficient physical memory to meet the RAM allocation requirements of the requestor.
Excessive use of swapping is called thrashing and is undesirable because it lowers overall system performance, mainly because hard drives are far slower than RAM. Continue reading “Thrashing Impact on C++ Performance: Doxygen Analysis”
As Bjarne Stroustrup points out, “C++ is a multi-paradigmed language.” It supports many different styles of programs, or paradigms, and object-oriented programming is only one of these. Some of the others are structured programming and generic programming.
And as Thomas Becker explains in this interesting article, there’s a tension between the generic programming and OOP. And here’s from the article the opinion of Alexander Stepanov and elder statesman about OOP: Continue reading “OOP vs Generics : “Is” vs “Has” approach.”
The V8 engine is Google’s open source, high-performance JavaScript engine written in C++. Alongside Google Chrome, it can also be found in MongoDb , Node.js, and many other popular applications.
It’s very interesting to discover what makes V8 so fast and which solutions were used to achieve this goal. Continue reading “Boost Performance with V8 Engine: A Design Choices Study”
MemCache++ is a light-weight, type-safe, simple to use and full-featured Memcache client. It was developed by Dean Michael Berris who is a C++ fanatic and currently works at Google Australia. He also is part of the Google delegation to the ISO C++ Committee.
Studying the well-designed libraries is recommended to elevate your C++ design and implementation skills, and the goal of this article is to discover some memcache++ design choices that make it easy to understand and use. Continue reading “Exploring Modern C++ Design: MemCache++ Case Study”
Back to 2005 when I worked in a company where most of the code was developed in C++, in 2006 the managers decide to develop the new projects with C# and also migrate some C++ projects to C#, here were their arguments against C++:
