Compiler warnings help developers write cleaner, safer, and more maintainable code. They help catch potential bugs early, enforce good practices, and improve code quality. But unless explicitly enabled, many compilers...

When we usually compile a C or C++ program, we just run a single command like gcc main.c -o test, and we have an executable. The compiler doesn't magically transform...

When you're working with C or C++ and using macros (via #define), it can be helpful to see what the preprocessor is actually doing - especially when debugging tricky macro...

When working with C or C++ code, it can be helpful to know what macros (via #define) the gcc or g++ compiler defines automatically. These predefined macros give you insight...

In heterogeneous environments that span multiple CPU architectures (e.g. x86_64, ARM), identifying the architecture of Docker images is an essential step for ensuring reliable builds and deployments. This is especially...

If you're learning how programs are translated into low-level instructions, or just curious about what the C or C++ code looks like at the assembly level, you can easily generate...

When working with big datasets on a GPU, it's helpful to keep values within a certain range. This process, called clamping, can be done quickly using parallel computing. It helps...

In many high-performance computing tasks - such as data preprocessing, graphics, or scientific simulations - we often need to perform operations on arrays, such as division by a scalar value...

When handling massive datasets or performance-intensive programs, speed and efficiency are essential. A frequently encountered task in such contexts is adding arrays together by summing each element with its counterpart...

Understanding and optimizing system startup performance is a key responsibility for any system administrator, especially in environments where uptime and responsiveness are critical. Slow boot times can signal underlying problems...
