  2. Apache Avro - Wikipedia

    en.wikipedia.org/wiki/Apache_Avro

    Apache Avro. Avro is a row-oriented remote procedure call and data serialization framework developed within Apache's Hadoop project. It uses JSON for defining data types and protocols, and serializes data in a compact binary format. Its primary use is in Apache Hadoop, where it can provide both a serialization format for persistent data, and a ...

  3. Persistence barcode - Wikipedia

    en.wikipedia.org/wiki/Persistence_barcode

    A persistence barcode is a complete invariant that captures all the topological information in a filtration. [2] In algebraic topology, the persistence barcodes were first introduced by Sergey Barannikov in 1994 as the "canonical forms" invariants [2] consisting of a multiset of line segments with ends on two parallel lines, and later, in ...

  4. Machine-readable medium and data - Wikipedia

    en.wikipedia.org/wiki/Machine-readable_medium...

    In communications and computing, a machine-readable medium (or computer-readable medium) is a medium capable of storing data in a format easily readable by a digital computer or a sensor. It contrasts with human-readable medium and data . The result is called machine-readable data or computer-readable data, and the data itself can be described ...

  5. Code 128 - Wikipedia

    en.wikipedia.org/wiki/Code_128

    A Swiss postal barcode encoding "RI 476 394 652 CH" in Code 128 (B & C) Code 128 is a high-density linear barcode symbology defined in ISO/IEC 15417:2007. [ 1] It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by use of an extension symbol (FNC4), the Latin-1 characters defined in ISO/IEC 8859 ...

  6. Barcode library - Wikipedia

    en.wikipedia.org/wiki/Barcode_library

    Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images ...

  7. Set (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Set_(abstract_data_type)

    Set (abstract data type) In computer science, a set is an abstract data type that can store unique values, without any particular order. It is a computer implementation of the mathematical concept of a finite set. Unlike most other collection types, rather than retrieving a specific element from a set, one typically tests a value for membership ...

  8. Aztec Code - Wikipedia

    en.wikipedia.org/wiki/Aztec_Code

    The total matrix capacity for a full symbol can be calculated as (112+16*L)*L for a full Aztec code and (88+16*L)*L for a compact Aztec code, where L is the symbol size in layers. [4] As an example, the total matrix capacity of a compact Aztec code with 1 layer is 104 bits. Since code words are six bits, this gives 17 code words and two extra bits.
