15 Essential C++11 Features to Enhance Your C++ Projects.

Over recent years, there has been much discussion about the “Renaissance of C++”. It’s undeniable that Microsoft played a significant role in this resurgence.

In 2011 Microsoft announced in many articles the comeback of C++, and Microsoft C++ experts like Herb Sutter attended many conferences to explain why C++ was back and mostly recommended the use of Modern C++. At the same time, the standard C++11 was approved and we began to talk about C++ as a new language. Continue reading “15 Essential C++11 Features to Enhance Your C++ Projects.”

Make Your Visual C++ Experience Much Better.

Visual C++ is one of the most used C++ IDEs which provides many interesting features to developers, each new version brings new major features and many extensions are available to add more nice features to it.In this post, I will talk about some useful features provided by CppDepend.

Why should you care about C/C++ static analysis?

Many resources discuss the benefits of using the static analysis tools, and how they could help you  improve your code base.  Somehow they show you what you could gain after using them. But did you asked yourself what do you lose if you don’t use them?

Let’s take an example of a memory corruption due to  free of a pointer twice, this cause random crash. It could take few hours or maybe many days to find this kind of issue. Many similar risky problems exist in C/C++ specially concerning memory corruption.  Just one problem could cost few dollars or many thousands of dollars.

Two easy approaches to leverage your C++ OOP design skills.

Coupling is usually contrasted with cohesion. Low coupling often correlates with high cohesion, and vice versa. Low coupling is often a sign of a well-structured computer system and a good design, and when combined with high cohesion, supports the general goals of high readability and maintainability. The goal of this case study is to show the benefits of loose coupling and high cohesion, and how it can be implemented with C++. The case study consists of designing an application that accesses a file in order to get data, processes it, and prints the result to an output file.

Exploring SQLite Codebase: Improve C++ Skills

16 years after its first checkin, SQLite is the most widely deployed database engine in the world. An open source project such as this is a good candidate for learning how to make your code easy to understand and to maintain.

Let’s discover some facts about the SQLite code base, beginning with the following code snippet: Continue reading “Exploring SQLite Codebase: Improve C++ Skills”

Optimize Memory in C++: Doxygen Case Study

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 “Optimize Memory in C++: Doxygen Case Study”

Managing Technical Debt with Agile Algorithm

Form wikipedia we can discover a brief explanation about the technical debt:

Technical debt (also known as design debt[1] or code debt) is “a concept in programming that reflects the extra development work that arises when code that is easy to implement in the short run is used instead of applying the best overall solution”.[2]

Technical debt can be compared to monetary debt.[3] If technical debt is not repaid, it can accumulate ‘interest’, making it harder to implement changes later on. Unaddressed technical debt increases software entropy. Technical debt is not necessarily a bad thing, and sometimes (e.g., as a proof-of-concept) technical debt is required to move projects forward. On the other hand, some experts claim that the “technical debt” metaphor tends to minimize the impact, which results in insufficient prioritization of the necessary work to correct it.[4][5]

Learn from Folly source code the new C++11 features.

Six years ago Facebook released their C++ library named Folly , it’s a large collection of reusable C++ library components that internally at Facebook are used extensively.

But many mature C++ open source libraries exist, why introduce another one ? Here’s the motivations from their website behind  its utility:

Folly (acronymed loosely after Facebook Open Source Library) is a library of C++11 components designed with practicality and efficiency in mind. It complements (as opposed to competing against) offerings such as Boost and of course std. In fact, we embark on defining our own component only when something we need is either not available, or does not meet the needed performance profile.
