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...
The bpftrace is a high-level tracing tool for Linux that allows developers and system administrators to write short scripts to investigate the behavior of the system, applications, or the kernel...
The uftrace is a tracing tool for Linux systems, particularly useful for tracing function calls in the applications. It helps developers understand the behavior of their applications by showing when...
Kyanos is a command line tool designed for real-time network traffic analysis using eBPF (Extended Berkeley Packet Filter) technology. It provides deep visibility into application-layer protocols such as HTTP, Redis...
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...
When developing in C or C++, macros defined with #define are powerful tools that can simplify code, improve readability, or enable conditional compilation - but they can also introduce subtle...
Loop vectorization is a powerful compiler optimization where repetitive operations (like array processing) are transformed into SIMD instructions. This allows the CPU to perform multiple operations in parallel using vector...
Reversing an array is a classic example that introduces essential CUDA concepts such as memory management, thread indexing, and kernel launches. Unlike serial programming on the CPU, where operations are...
