  2. MIDI - Wikipedia

    en.wikipedia.org/wiki/MIDI

    MIDI interfaces intended for use as the centerpiece of a studio, such as the Mark of the Unicorn MIDI Time Piece, were made possible by a "fast" transmission mode that could take advantage of these serial ports' ability to operate at 20 times the standard MIDI speed. [2]: 62–3 [139] Mini-DIN ports were built into some late-1990s MIDI ...

  3. Warp drive - Wikipedia

    en.wikipedia.org/wiki/Warp_drive

    Warp drive. A warp drive or a drive enabling space warp is a fictional superluminal (faster than the speed of light) spacecraft propulsion system in many science fiction works, most notably Star Trek, [1] and a subject of ongoing physics research. The general concept of "warp drive" was introduced by John W. Campbell in his 1957 novel Islands ...

  4. Hard disk drive performance characteristics - Wikipedia

    en.wikipedia.org/wiki/Hard_disk_drive...

    The first HDD [11] had an average seek time of about 600 ms. [12] and by the middle 1970s, HDDs were available with seek times of about 25 ms. [13]Some early PC drives used a stepper motor to move the heads, and as a result had seek times as slow as 80–120 ms, but this was quickly improved by voice coil type actuation in the 1980s, reducing seek times to around 20 ms.

  5. Speedrunning - Wikipedia

    en.wikipedia.org/wiki/Speedrunning

    The development of a strong speedrunning community is considered to have originated with the 1993 computer game Doom. [2] [3] [4] The game retained the "par time" mechanic from Wolfenstein and included a feature that allowed players to record and play back gameplay using files called demos (also known as game replays).

  7. Amdahl's law - Wikipedia

    en.wikipedia.org/wiki/Amdahl's_law

    Then we are told that the 1st part is not sped up, so s1 = 1, while the 2nd part is sped up 5 times, so s2 = 5, the 3rd part is sped up 20 times, so s3 = 20, and the 4th part is sped up 1.6 times, so s4 = 1.6. By using Amdahl's law, the overall speedup is

  8. Audio time stretching and pitch scaling - Wikipedia

    en.wikipedia.org/wiki/Audio_time_stretching_and...

    Time stretching is the process of changing the speed or duration of an audio signal without affecting its pitch. Pitch scaling is the opposite: the process of changing the pitch without affecting the speed. Pitch shift is pitch scaling implemented in an effects unit and intended for live performance. Pitch control is a simpler process which ...

  9. Time complexity - Wikipedia

    en.wikipedia.org/wiki/Time_complexity

    An algorithm is said to be exponential time, if T(n) is upper bounded by 2 poly(n), where poly(n) is some polynomial in n. More formally, an algorithm is exponential time if T(n) is bounded by O(2 n k) for some constant k. Problems which admit exponential time algorithms on a deterministic Turing machine form the complexity class known as EXP.
