Boolean and bit operators are not the same.

How to Short-Circuit a Sequence of Operations with a Boolean Value

by Jonathan Boccara

From the article:

Interrupting a sequence of operations when one of them fails is a common problem in computer programming. There are plenty of elaborate ways to code that, ranging from exceptions to monads to static exceptions.

One of the techniques to stop such a sequence of operations that is not so sophisticated, but that can be found in existing code, is to use a boolean. This relies on each step producing a boolean flag to indicate if it succeeded or failed, and to stop executing steps at the first failure.

However, simple as it is, this technique can lead to code that doesn’t do with it looks like...

The C++ Lifetime Profile: How It Plans to Make C++ Code Safer--Daniel Martín

A way to make C++ safer.

The C++ Lifetime Profile: How It Plans to Make C++ Code Safer

by Daniel Martín

From the article:

High amounts of low-level systems are written in C++. Memory access in C++ is virtually unrestricted, which means that bugs in C++ programs can corrupt it and cause crashes or security problems. For this reason, we call C++ a memory-unsafe programming language — in contrast to memory-safe languages like Java, Rust, and Swift.

In this blog post, I’ll talk about the C++ Lifetime Profile, explaining what it is, how it intends to reduce the problems typically caused by the memory-unsafe characteristics of C++, what the status of the current implementation of the Lifetime Profile is, and what the current limitations are...

From the article:

From medical devices and flash storage to CPUs and advanced navigation systems, Israeli innovation pushes the boundaries of the imagination. Advanced software is at the heart of many of these systems, and when it comes to bare-metal performance, low power-consumption and massive scalability, C++ is king. Core C++ 2020 will take place at The Wohl Conventions Center, located just outside Tel-Aviv on the campus of Bar-Ilan University in Ramat Gan, Israel.
The conference is aimed at C++ developers and practitioners as well as academic researchers and teachers who wish to be updated by the newest developments of C++ and present their work with C++. International speakers and attendees are more than welcome to join us!

How and why overloading, templates, and auto deduction invented?

by Milad Kahsari

From the article:

Why we need the template function/classes and how this concept created by C++ compiler engineers? In this medium post, I want to go through the steps which made c++ experts think about the template concept and auto in the modern days of software development.
