  2. BED (file format) - Wikipedia

    en.wikipedia.org/wiki/BED_(file_format)

    BEDTools: program allowing the manipulation of coordinate sets and the extraction of sequences from a BED file. [6] BEDOPS: a suite of tools for fast boolean operations on BED files. [8] BedTk: a faster alternative to BEDTools for a limited and specialized sub-set of operations. [9] covtobed: a tool to convert a BAM file into a BED coverage ...

  3. Dangling pointer - Wikipedia

    en.wikipedia.org/wiki/Dangling_pointer

    This technique does not help when there are multiple copies of the pointer. Some debuggers will automatically overwrite and destroy data that has been freed, usually with a specific pattern, such as 0xDEADBEEF (Microsoft's Visual C/C++ debugger, for example, uses 0xCC, 0xCD or 0xDD depending on what has been freed [7]). This usually prevents ...

  4. Compass - Wikipedia

    en.wikipedia.org/wiki/Compass

    A modern military compass, with included sight device for aligning. A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north.

  5. Direction determination - Wikipedia

    en.wikipedia.org/wiki/Direction_determination

    Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.

    en.wikipedia.org/wiki/Linked_list

    record Node { data; // The data being stored in the node Node next // A reference [2] to the next node, null for last node } record List { Node firstNode // points to first node of list; null for empty list} Traversal of a singly linked list is simple, beginning at the first node and following each next link until reaching the end:

  8. Strike and dip - Wikipedia

    en.wikipedia.org/wiki/Strike_and_dip

    Strike and dip are measured in the field using a compass and with a clinometer. A compass is used to measure the azimuth of the strike, and the clinometer measures inclination of the dip. [2] Dr. E. Clar first described the modern compass-clinometer in 1954, and some continue to be referred to as Clar compasses. [10]

  9. Compass equivalence theorem - Wikipedia

    en.wikipedia.org/wiki/Compass_equivalence_theorem

    In geometry, the compass equivalence theorem is an important statement in compass and straightedge constructions. The tool advocated by Plato in these constructions is a divider or collapsing compass , that is, a compass that "collapses" whenever it is lifted from a page, so that it may not be directly used to transfer distances.
