Knowing the exact build date and time of the Linux kernel can be useful for debugging, system audits, or just general curiosity. This tutorial demonstrates how to get Linux kernel...
Locking the screen is a simple but essential step in protecting the system when stepping away. It is very useful when working in a shared space or just want to...
When managing Linux systems, especially across different hardware platforms, it's often essential to know the CPU architecture of the machine. Whether you're compiling software, troubleshooting hardware compatibility, or deploying container...
In performance-critical applications like game engines, real-time simulations, or high-throughput data processing, handling large arrays efficiently is crucial. One common operation you might encounter is clamping all positive values in...
When working with C++ projects, knowing the exact version of the compiler used to build the code can be crucial for debugging, compatibility checks, or simply documenting the build environment...
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...
