  3. LZ4 (compression algorithm) - Wikipedia

    en.wikipedia.org/wiki/LZ4_(compression_algorithm)

    Each sequence begins with a one-byte token that is broken into two 4-bit fields. The first field represents the number of literal bytes that are to be copied to the output. The second field represents the number of bytes to copy from the already decoded output buffer (with 0 representing the minimum match length of 4 bytes).

    The Python programming language has a builtin plistlib module to read and write plist files, in Apple's XML or in binary (since Python 3.4). [28] ProperTree is a cross-platform editor that makes use of this library.

  6. Filename - Wikipedia

    In the Finder, filenames containing / can be created, but / is stored as a colon (:) in the filesystem, and is shown as such on the command line. Filenames containing : created from the command line are shown with / instead of : in the Finder, so that it is impossible to create a file that the Finder shows as having a : in its filename. 255

    en.wikipedia.org/wiki/DEFLATE

    For example, a run of 10 identical bytes can be encoded as one byte, followed by a duplicate of length 9, beginning with the previous byte. Searching the preceding text for duplicate substrings is the most computationally expensive part of the DEFLATE algorithm, and the operation which compression level settings affect.

  8. Bitstream - Wikipedia

    en.wikipedia.org/wiki/Bitstream

    Although typically implemented in low-level languages, some high-level languages such as Python [1] and Java [2] offer native interfaces for bitstream I/O. One well-known example of a communication protocol which provides a byte-stream service to its clients is the Transmission Control Protocol (TCP) of the Internet protocol suite , which ...

  9. Zero-byte file - Wikipedia

    en.wikipedia.org/wiki/Zero-byte_file

    Zero-byte files may arise in cases where a program creates a file but aborts or is interrupted prematurely while writing to it. Because writes are cached in memory and only flushed to disk at a later time , a program that does not flush its writes to disk or terminate normally may result in a zero-byte file. When the zero-byte file is made ...
