Ccache stores compiled objects and related metadata in a cache directory. Over time, the cache can become large, which might put pressure on the disk if not properly managed. To...

When using Ccache to speed up compilation, all cached object files and metadata are stored in a local directory. By default, on most systems, this directory is located inside the...
Ccache helps developers save valuable time by reusing previously compiled objects, significantly reducing build times during recompilation. However, a common challenge when working with Ccache is figuring out which configuration...
Multithreading can dramatically boost program performance - but it also introduces subtle, dangerous bugs like data races, which are notoriously hard to detect with traditional debugging techniques. Thankfully, tools such...
When optimizing software performance, it's crucial to understand where the program spends its time. If you're working with C or C++ programs compiled using gcc or g++, a useful profiling...
When working with C or C++ projects, specifying the language standard during compilation is a good practice that helps ensure consistency, portability, and future-proofing of the code. If we don't...
Modern compilers often apply auto-vectorization to loops to improve performance by utilizing SIMD instructions. This enables the CPU to execute multiple operations simultaneously using vector registers, significantly enhancing performance in...
Before merging or deleting a branch, it's a good idea to compare it with another branch. This helps to review the changes it contains and decide whether it's ready to...
When writing C or C++ code, it's essential to ensure the code complies with the intended language standard, especially if you're targeting environments that require strict compatibility (e.g., embedded systems...
Memory errors like use-after-free, buffer overflows, and memory leaks are some of the most common bugs in C and C++ - and some of the hardest to debug. Fortunately, the...
