Review # 1 was written on 2015-12-11 00:00:00 Rolando Corrales An enjoyable read, treating the problem of data compression at more or less the level I wanted it to. Has its share of rough edges, though. I appreciate that the authors made the effort to avoid pseudo-code and provide working C code for every algorithm, but because everything sucked so much more in 1995 and because Nelson wanted DOS support, that code tends to have a lot of boilerplate noise; combined with the fact that whole-program implementations are provided for everything (including at least one program pretty unrelated to compression), something like half of the book is just code. That's a bit excessive, especially considering that the included floppy disk has another copy of that code anyway (presumably; I'm not even sure I own a working 3½-inch drive so I didn't check). Another problem is that the focus is very much on how, and not so much on why. Sometimes the why is obvious—it's clear why Shannon-Fano and Huffman coding tend to compress data, and why Huffman is better at it than Shannon-Fano, for example—but when it's not, the authors make no attempt to explain—though I could certainly write my own implementation now, I still don't have a decent feel for why arithmetic coding compresses at all. In the end, The Data Compression Book really doesn't deserve its reputation as the book on data compression, but if you just want an easy-to-follow discussion of the main algorithms that are unfiddly enough that you could conceivably want to implement them for fun, you could certainly do a lot worse. (To be perfectly honest, though, you could probably also do better with just its table of contents and Wikipedia.)
