  2. Flood fill - Wikipedia

    en.wikipedia.org/wiki/Flood_fill

    Flood fill, also called seed fill, is a flooding algorithm that determines and alters the area connected to a given node in a multi-dimensional array with some matching attribute. It is used in the "bucket" fill tool of paint programs to fill connected, similarly colored areas with a different color, and in games such as Go and Minesweeper for ...

  3. NOP slide - Wikipedia

    en.wikipedia.org/wiki/NOP_slide

    A NOP-sled is the oldest and most widely known technique for exploiting stack buffer overflows. [2] It solves the problem of finding the exact address of the buffer by effectively increasing the size of the target area. To do this, much larger sections of the stack are corrupted with the no-op machine instruction.

  4. Shunting yard algorithm - Wikipedia

    en.wikipedia.org/wiki/Shunting_yard_algorithm

    It can produce either a postfix notation string, also known as reverse Polish notation (RPN), or an abstract syntax tree (AST). [1] The algorithm was invented by Edsger Dijkstra , first published in November 1961, [ 2 ] and named the "shunting yard" algorithm because its operation resembles that of a railroad shunting yard .

  5. Stack Overflow - Wikipedia

    en.wikipedia.org/wiki/Stack_Overflow

    Stack Overflow is a question-and-answer website for computer programmers. It is the flagship site of the Stack Exchange Network . [ 2 ] [ 3 ] [ 4 ] It was created in 2008 by Jeff Atwood and Joel Spolsky .

  6. Stack buffer overflow - Wikipedia

    en.wikipedia.org/wiki/Stack_buffer_overflow

    A stack buffer overflow can be caused deliberately as part of an attack known as stack smashing. If the affected program is running with special privileges, or accepts data from untrusted network hosts (e.g. a webserver ) then the bug is a potential security vulnerability .

  7. NOP (code) - Wikipedia

    en.wikipedia.org/wiki/NOP_(code)

    0x66 is the operand-size override prefix. 0x0F 0x1F is a two-byte NOP opcode that takes a ModR/M operand upon which no operation is performed; 0x00 is [EAX], 0x40 0x00 is [EAX + 00H], 0x44 0x00 0x00 is [EAX + EAX*1 + 00H], 0x80 0x00 0x00 0x00 0x00 is [EAX + 00000000H], and 0x84 0x00 0x00 0x00 0x00 0x00 is [EAX + EAX*1 + 00000000H].

    ImHex is a free cross-platform hex editor available on Windows, macOS, and Linux. [ 1 ] ImHex is used by programmers and reverse engineers to view and analyze binary data.

  9. x86 memory segmentation - Wikipedia

    en.wikipedia.org/wiki/X86_memory_segmentation

    Instructions are always fetched from the code segment. Any stack push or pop or any data reference referring to the stack uses the stack segment. All other references to data use the data segment. The extra segment is the default destination for string operations (for example MOVS or CMPS). FS and GS have no hardware-assigned uses.
