    *Compressor Head, Episode 2: The LZ Compression Family*
    /with Colt McAnlis #everybitcounts #compressorhead #developers
    In the world of compression, one algorithm family reigns supreme. Born in the late 70s, the Lempel-Ziv algorithms have become the most dominant dictionary encoding schemes in compression. +Colt McAnlis walks us through why these algorithms are so dominant in this episode of Compressor Head.

      Very enjoyable and informative. Thanks for doing these videos. All three were great.

      I always use LZMA for all of my compression needs, unless I have to send it to Windows users, of course, in which case I use ZIP.

    I'm just implementing some compression algorithms on my master thesis and your videos are nice start for getting some intuition.

    6:39 why is the window moved to before the B?? Shouldn't it be after the B?

    📺💬 We talking about likely on the cross-bit entropy where the longest string represents more than one in the encoding text we can substitute the text string with a set of bits numbers followed by other words in sequences, which is the same as WinZip is doing in the previous method.
    🧸💬 There is an allowed policy that to use distribution with self-generated text stream because they avoid the data in the standard dictionary that sound conflicts but create security.
    👧💬 Security is not an absolute goal but maximizing the compression rates too, creating random generate cross-entropy, asymmetric encryption algorithms, and asymmetric encryption algorithms.
    📺💬 The first algorithm is the longest matching search next are LZ77 and LZ78 which look ahead backward, for good compression, and are in the English language as natural. 🧸💬 We had some question hints we play ปปลาตากลม or symmetric word that had both sides meaning or letter composer had skills to create transmission letters but now it is not required because of communication bandwidths development but some work are using such as signs, templates, and translation.
    👧💬 It mirrors letters and forward-backward algorithms but important is you carry a divider number with the letter transmission and when you send example locations and priority they need to guess what is your divider from all the transmitting sequences.
    🧸💬 We added Symbols to break algorithms.
    📺💬 LZMA is one algorithm we call the Markov chains algorithm that is very useful and using it until today.
    👧💬 yes, it is powerful and no one can compare but it uses a lot of power calculation so we try to make alternative ways or options to work on it such as Neuron networks or partial computation.

      The point is to be distracting, it breaks up the discussions which can tend to seem rather dry. There's likely something to teachers making bad jokes that make them better teachers.

    Is the example from 4:26 follow the prefix rule? It seems like the "t" and "tobe...ornot" share the same prefix.
