representation; binary arithmetic and bit operations; floating point
|
||
|
|
representation; system and memory organization; character representation;
|
||
|
|
constants and types; digital design; CPU, instruction set, and memory
|
||
|
|
architecture; input and output; and how compilers work.</p>

<p>"Great code" is machine dependent and written in assembly. Or, at least,
|
||
|
|
that's what this book makes you believe till the very last chapter, when it
|
||
|
|
starts backtracking about writing code directly into CPU code.</p>
|
||
|
|
<p>Now, don't get me wrong, it's not a terrible book -- it's a damn complete book
|
||
|
|
about <em>computer architecture</em>, even being so out-of-date that there is no word
|
||
|
|
about SSDs (when talking about storage), no mention about MP3s (when
|
||
|
|
discussing about audio hardware), the top CPU discussed is Pentium, there is
|
||
|
|
no word about UTF-8 (and mentions ASCII is used all around) and recommending
|
||
|
|
search things on AltaVista. </p>
|
||
|
|
<p>The problem is discussing all this when the topic is "great code": Great code
|
||
|
|
is not machine dependent; great code is not highly optimized code that runs
|
||
|
|
extremely fast and uses very little memory; there are trade offs that you have
|
||
|
|
to take in account when coding: Sure, you don't write something that uses all
|
||
|
|
the available memory, but you write in a language that allows you to easily
|
||
|
|
extend the code later and which your code reads exactly what you meant it to
|
||
|
|
say. That's great code, not code that uses some multimedia extensions that is
|
||
|
|
available since a very specific generation of CPUs.</p>
|
||
|
|
<p>The book also goes into great lengths to explain stuff that is hardly useful.
|
||
|
|
For example, there is a whole implementation of the floating point standard
|
||
|
|
(IEEE 754), which is not optimized -- so, no great code -- and that's
|
||
|
|
absolutely unnecessary, since this is done directly into the CPU (and, if it
|
||
|
|
isn't, you have libraries ready for that).</p>
|
||
|
|
<p>It could be that the "Great Code" will come in the later volumes, but ignoring
|
||
|
|
what <em>is</em> great code (I mean, <em>real</em> great code) and just building a base for
|
||
|
|
later is plainly greedy.</p>
