| | [AI summary] The text provides an in-depth exploration of various x86-64 instruction set architectures, focusing on arithmetic operations (ADD, SUB, MUL, SMUL, DIV, SDIV), logical operations (AND, OR, XOR, NOT), and control flow instructions. It details the implementation of these instructions in the QBX virtual machine, emphasizing how they emulate real x86-64 instructions while managing the flags register and handling different operand sizes (8-bit and 16-bit). The text also discusses the nuances of flag handling, register operations, and macro-based code generation to streamline instruction implementation.

| | I was recently on a video call with a friend, throwing around some ideas for a new product. I mentioned adding large signed numbers in assembly and using two's complement. He asked me what two's complement was. I was a little surprised that he didn't know. He's been a Java programmer for more than 30 years. Java and Python programmers (and others like gasp Commodore / MicroSoft BASIC) don't have a native unsigned integer type. The language takes care of the details for you.

| Closer to the machine I started my way with programming with Microsoft QBASIC on DOS, I did try (and succeed) to copy code for a game from a BASIC book, and it did run, but I didnt really get development back then. I didnt really understand how and why it works, and most importantly, how to write my own code to implement a different game. Later I was playing higher level languages such as Pascal and C in the high school and PHP at home.
