  2. Spinlock - Wikipedia

    en.wikipedia.org/wiki/Spinlock

    The Hardware Lock Elision (HLE) in x86 is a weakened but backwards-compatible version of TSE, and we can use it here for locking without losing any compatibility. In this particular case, the processor can choose to not lock until two threads actually conflict with each other.

  3. Windows 10 - Wikipedia

    en.wikipedia.org/wiki/Windows_10

    The 32-bit variants of Windows 10 will remain available via non-OEM channels, and Microsoft will continue to "[provide] feature and security updates on these devices". [289] This was later followed by Windows 11 dropping support for 32-bit hardware altogether, thus making Windows 10 the final version of Windows to have a 32-bit version ...

  4. Log rotation - Wikipedia

    en.wikipedia.org/wiki/Log_rotation

    In information technology, log rotation is an automated process used in system administration in which log files are compressed, moved , renamed or deleted once they are too old or too big (there can be other metrics that can apply here). New incoming log data is directed into a new fresh file (at the same location).

  5. Xorshift - Wikipedia

    en.wikipedia.org/wiki/Xorshift

    A C version [a] of three xorshift algorithms [1]: 4,5 is given here. The first has one 32-bit word of state, and period 2 32 −1. The second has one 64-bit word of state and period 2 64 −1. The last one has four 32-bit words of state, and period 2 128 −1. The 128-bit algorithm passes the diehard tests.

  6. Rotary combination lock - Wikipedia

    en.wikipedia.org/wiki/Rotary_combination_lock

    Many combination locks have three wheels, but the lock may be equipped with additional wheels, each with a drive pin and fly, in a similar manner. The number of wheels in the mechanism determines the number of specific dial positions that must be entered to open the lock, so a three-sequence combination is required for a three-wheel lock.

  7. Linear-feedback shift register - Wikipedia

    en.wikipedia.org/wiki/Linear-feedback_shift_register

    A Fibonacci 31 bit linear feedback shift register with taps at positions 28 and 31, giving it a maximum cycle and period at this speed of nearly 6.7 years. The bit positions that affect the next state are called the taps. In the diagram the taps are [16,14,13,11]. The rightmost bit of the LFSR is called the output bit, which is always also a tap.

  8. Warded lock - Wikipedia

    en.wikipedia.org/wiki/Warded_lock

    A warded lock (also called a ward lock) is a type of lock that uses a set of obstructions, or wards, to prevent the lock from opening unless the correct key is inserted. The correct key has notches or slots corresponding to the obstructions in the lock, allowing it to rotate freely inside the lock.

  9. Autorotation - Wikipedia

    en.wikipedia.org/wiki/Autorotation

    If the engine fails, the freewheeling unit automatically disengages the engine from the main rotor, allowing the main rotor to rotate freely. The most common reason for autorotation is an engine malfunction or failure, but autorotation can also be performed in the event of a complete tail rotor failure, or following loss of tail-rotor ...
