  2. Integer overflow - Wikipedia

    en.wikipedia.org/wiki/Integer_overflow

    The register width of a processor determines the range of values that can be represented in its registers. Though the vast majority of computers can perform multiple-precision arithmetic on operands in memory, allowing numbers to be arbitrarily long and overflow to be avoided, the register width limits the sizes of numbers that can be operated on (e.g., added or subtracted) using a single ...

  3. Array programming - Wikipedia

    en.wikipedia.org/wiki/Array_programming

    The previous statements are also valid MATLAB expressions if the third one is executed before the others (numerical comparisons may be false because of round-off errors). If the system is overdetermined – so that A has more rows than columns – the pseudoinverse A + (in MATLAB and GNU Octave languages: pinv(A) ) can replace the inverse A − ...

  4. Code injection - Wikipedia

    en.wikipedia.org/wiki/Code_injection

    At runtime, a canary is checked when a function returns. If a canary has been modified, the program stops execution and exits. This occurs on a failed Stack Overflow Attack. Code Pointer Masking (CPM): after loading a (potentially changed) code pointer into a register, the user can apply a bitmask to the pointer. This effectively restricts the ...

  5. Lazy evaluation - Wikipedia

    en.wikipedia.org/wiki/Lazy_evaluation

    In many other languages, evaluation can be delayed by explicitly suspending the computation using special syntax (as with Scheme's "delay" and "force" and OCaml's "lazy" and "Lazy.force") or, more generally, by wrapping the expression in a thunk. The object representing such an explicitly delayed evaluation is called a lazy future.

  6. Halt and Catch Fire (computing) - Wikipedia

    en.wikipedia.org/wiki/Halt_and_Catch_Fire...

    The Intel 8086 and subsequent processors in the x86 series have an HLT (halt) instruction, opcode F4, which stops instruction execution and places the processor in a HALT state. An enabled interrupt, a debug exception, the BINIT signal, the INIT signal, or the RESET signal resumes execution, which means the processor can always be restarted. [15]

  7. For loop - Wikipedia

    en.wikipedia.org/wiki/For_loop

    If the result were false the for-loop's execution stops short. Granted that the loop variable's value is defined after the termination of the loop, then the above statement will find the first non-positive element in array A (and if no such, its value will be N + 1 ), or, with suitable variations, the first non-blank character in a string, and ...

  8. Infinite loop - Wikipedia

    en.wikipedia.org/wiki/Infinite_loop

    If the main thread exits, all threads of the process are forcefully stopped, thus all execution ends and the process/program terminates. The threads inside the infinite loops can perform "housekeeping" tasks or they can be in a blocked state waiting for input (from socket/queue) and resume execution every time input is received.

  9. Truncation error (numerical integration) - Wikipedia

    Suppose we have a continuous differential equation ′ = (,), =, and we wish to compute an approximation of the true solution () at discrete time steps ,, …,.For simplicity, assume the time steps are equally spaced:
