or rX,rX,rX with X=1,2,3,5,6,7 or 31 sets thread priority based on X. or r26,r26,r26 is a memory store writeback hint. xori r0,r0,0 is an explicitly unoptimized no-op for use in timing-loops. and rX,rX,rX with X=0,1 are performance-probe no-ops. ori r2,r2,0 is a "group ending NOP" in some POWER CPUs [9] PIC microcontroller: NOP: 12 bits ...
Visualization of a software buffer overflow. Data is written into A, but is too large to fit within A, so it overflows into B.. In programming and information security, a buffer overflow or buffer overrun is an anomaly whereby a program writes data to a buffer beyond the buffer's allocated memory, overwriting adjacent memory locations.
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.
Stack buffer overflow is a type of the more general programming malfunction known as buffer overflow (or buffer overrun). Overfilling a buffer on the stack is more likely to derail program execution than overfilling a buffer on the heap because the stack contains the return addresses for all active function calls. [1] Stack buffer overflow can ...

The R-755 was first run in 1933 and was still in production in the 1970s. With a bore and stroke of 5.25 in × 5 in (133 mm × 127 mm) the displacement was 757 cu in (12.4 L), power ranged from 200 hp to 350 hp (150 kW - 260 kW).
The Rolls-Royce Trent 1000 is a high-bypass turbofan engine produced by Rolls-Royce, one of the two engine options for the Boeing 787 Dreamliner, competing with the General Electric GEnx. It first ran on 14 February 2006 and first flew on 18 June 2007 before a joint EASA/FAA certification on 7 August 2007 and entered service on 26 October 2011.
Buffer overflow, a situation whereby the incoming data size exceeds that which can be accommodated by a buffer. Heap overflow, a type of buffer overflow that occurs in the heap data area; Overflow (software), a NASA-developed computational fluid dynamics program using overset (Chimera) grids; Overflow condition, a situation that occurs when ...
