Travel
| | [AI summary] The article discusses the process of learning to read x86 assembly language, focusing on how it can be a useful skill for understanding low-level operations of microprocessors. It outlines the challenges of reading assembly, especially in debugging scenarios, and provides an example of translating Ruby code into x86 assembly using Crystal. The article also explains the syntax and structure of x86 assembly, including register usage, instruction suffixes, and the differences between AT&T and Intel syntax. It highlights the complexity of x86 assembly due to its historical evolution and the need for understanding register sizes and operand notation.

| tl;dr "Transparent Hugepages" is a Linux kernel feature intended to improve performance by making more efficient use of your processor's memory-mapping hardware. It is enabled ("enabled=always") by default in most Linux distributions. Transparent Hugepages gives some applications a small performance improvement (~ 10% at best, 0-3% more typically), but can cause significant performance problems, or even apparent memory leaks at worst. To avoid these problems, you should set enabled=madvise on your server...
