A binary tree can be empty, implying zero nodes in the tree. The cool thing about binary trees is that they are recursive structures. » DEV Community | dev.to

The dynamic creation and destruction of objects was always one of the bugbears of C. It required the programmer to (manually) control the allocation of memory for the object, handle the object’s initialisation then ensure that the object was safely cleaned-up after use and its memory returned to the heap. Because many C programmers weren’t educated in the potential problems (or were just plain lazy or delinquent in their programming) C got a reputation in some quarters for being an unsafe, memory-leaking language. ...

DOS Lab IIT Madras and CDAC Chennai out of India are aiming to redesign the Linux kernel as MOOL, or the Minimalistic Object Oriented Linux. The project site explains, ”MOOL (Minimalistic Object Oriented Linux) aims at redesigning the Linux kernel to reduce coupling and increase maintainability by means of OO (Object Oriented) abstractions. Excessive common coupling prevails in existing kernel. Studies have shown that common coupling is increasing in successive versions of Linux. This will make maintainability of Linux difficult in coming years. As a starting step we have tried to reduce the number of global variables of the kernel. Some global variables are used only by two or three kernel modules. These are passed as function arguments. The performance of the modified kernel is measured with the standard performance analysis tools. The modified kernel performs almost same as original. MOOL features a device driver framework to write drivers in C++ and insert them as loadable kernel modules.” ...

Lock-free programming is a challenge, not just because of the complexity of the task itself, but because of how difficult it can be to penetrate the subject in the first place. I was fortunate in that my first introduction to lock-free (also known as lockless) programming was Bruce Dawson’s excellent and comprehensive white paper, Lockless Programming Considerations. And like many, I’ve had the occasion to put Bruce’s advice into practice developing and debugging lock-free code on platforms such as the Xbox 360. Since then, a lot of good material has been written, ranging from abstract theory and proofs of correctness to practical examples and hardware details. I’ll leave a list of references in the footnotes. At times, the information in one source may appear orthogonal to other sources: For instance, some material assumes sequential consistency, and thus sidesteps the memory ordering issues which typically plague lock-free C/C++ code. The new C++11 atomic library standard throws another wrench into the works, challenging the way many of us express lock-free algorithms. In this post, I’d like to re-introduce lock-free programming, first by defining it, then by distilling most of the information down to a few key concepts. I’ll show how those concepts relate to one another using flowcharts, then we’ll dip our toes into the details a little bit. At a minimum, any programmer who dives into lock-free programming should already understand how to write correct multithreaded code using mutexes, and other high-level synchronization objects such as semaphores and events. ...
