The encoding of x86 and x86-64 instructions is well documented in Intel or AMD’s manuals. However, they are not quite easy for beginners to start with to learn encoding of the x86-64 instructions. In this post, I will give a list of useful manuals for understanding and studying the x86-64 instruction encoding, a brief introduction…
Understanding HTML Entities HTML entities let you display characters that aren’t easily typed on a keyboard or have special meaning in HTML. Any character can be represented in three ways: Named entity: &name; (e.g., ©) Decimal numeric: &#number; (e.g., ©) Hexadecimal numeric: &#xhexcode; (e.g., ©) Modern browsers handle UTF-8 encoding well, so for most special…
