The Internet of Things (IoT) refers to the network of physical objects—devices, vehicles, buildings, and other items—embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet. IoT encompasses a wide range of applications, from consumer gadgets to industrial systems, transforming how we interact with the physical world.
The Folly library, developed by Facebook, is a collection of reusable C++ library components designed to complement the C++ standard library and boost the performance of C++ applications. Folly focuses on efficiency, providing highly optimized components that are particularly useful in performance-critical applications. Here are some key aspects of performance in the Folly library:
Continue reading “Boosting C++ Performance with Folly”2011 marked the renaissance of C++, driven by the release of C++11 which introduced numerous features to modernize the language, such as lambda expressions, smart pointers, and a more efficient standard library. However, a decade later, major tech giants like Google, Microsoft, Amazon, Apple, and Meta are initiating processes to migrate away from C++. This shift highlights growing concerns about memory safety and the evolving landscape of systems programming.
Just recently there’s another big company joining the Moving away from C++ initiative. it concern Apple that recommend to replace C++ with Swift.
One could argue that the issue lies not with C++ itself, but with the developers using it. However, the reality is that big companies are shifting away from C++.

However, it’s also been the subject of significant criticism over the years. Interestingly, these criticisms often have an unintended consequence, making C++ even more popular—a phenomenon known as the Streisand Effect.
Recently, C++ faced widespread criticism, with even the White House advising against its use. Ironically, this led to an increase in its popularity. According to TIOBE, C++ has surpassed C in popularity for the first time in history.
Continue reading “According to Tiobe C++ surpasses C for the first time in history, The Streisand Effect works :)”Recently, Herb Sutter wrote an excellent article on C++ safety. He discussed numerous ideas, but I’ll provide a summary of his perspective on what can be done in the medium term to enhance C++ safety.
| In C++, by default enforce … | (A) Solution for new/updated code (can require code changes — no link/binary changes) | (B) Solution for existing code (requires recompile only — no manual code changes, no link/binary changes) |
| Type safety | Ban all inherently unsafe casts and conversions | Make unsafe casts and conversions with a safe alternative do the safe thing |
| Bounds safety | Ban pointer arithmetic Ban unchecked iterator arithmetic | Check in-bounds for all allowed iterator arithmetic Check in-bounds for all subscript operations |
| Initialization safety | Require all variables to be initialized (either at declaration, or before first use) | — |
| Lifetime safety | Statically diagnose many common pointer/iterator lifetime error cases | Check not-null for all pointer dereferences |
| Less undefined behavior | Statically diagnose known UB/bug cases, to error on actual bugs in existing code with just a recompile and zero false positives: Ban mathematically invalid comparison chains (add additional cases from UB Annex review) | Automatically fix known UB/bug cases, to make current bugs in existing code be actually correct with just a recompile and zero false positives: Define mathematically valid comparison chains Default return *this; for C assignment operators that return C& (add additional cases from UB Annex review) |
But what are the current possibilities for achieving this goal?

C++ is not an exception. Understanding why a feature is added can significantly enhance how developers use it, leading to better, more maintainable code.
For C++ developers who have not yet mastered the new C++ features, it’s recommended to understand at least one key motivation behind each feature. This way, when a specific need arises, the developer can identify which feature might be useful and then delve deeper into learning how to implement it.
Here are the motivations behind some new C++ features:

// Hello world demo

]It’s the BCPL programming language . BCPL (Basic Combined Programming Language) is a foundational language in the history of programming languages. Developed by Martin Richards in 1966, BCPL’s simplicity, typeless nature, and portability were key features that influenced the design of many subsequent languages, including B and C. Its impact is particularly notable in the development of system software and compilers, making it a critical step in the evolution of programming languages.
Continue reading “Back 60 years ago marked the rise of the ancestor of C/C++, thanks to Martin Richards.”Bloggers, influencers, and the C++ Standard Committee actively advocate for the use of Modern C++. Through articles, tutorials, and social media, bloggers and influencers highlight the benefits and innovative features of the latest C++ standards, aiming to educate and inspire the programming community. Their collective efforts are geared towards encouraging developers to adopt Modern C++, leveraging its advanced capabilities to write more efficient, maintainable, and robust code.
However, not all C++ developers agree with adopting Modern C++ for various reasons, leading to the emergence of the Orthodox C++ approach, which advocates for using a minimal subset of C++.
Continue reading “Orthodox C++ fans: are they a minority or a silent majority?”Modern C++ has seen a series of significant updates starting from C++11, each bringing new features and enhancements that aim to make the language more efficient, readable, and maintainable. Here’s a brief overview of the major features introduced in each version since C++11, along with a comment on their usage:
C++11 marked a significant evolution in the C++ language, introducing several powerful features that modernized and simplified C++ programming. Here are some of the most impactful features, along with examples to illustrate their usage:
