advance (though not to strncmp), this complexity is unnecessary; we know the counts are right so checking for the \O wastes time Third, s t r c h r is also complex, since it must look for the character and also watch for the \O byte that terminates the message For a given call to isspam, the message is fixed, so time spent looking for the \O is wasted since we know where the message ends Finally, although strncmp, s t r c h r , and s t r l e n are all efficient in isolation, the overhead of calling these functions is comparable to the cost of the calculation they will perform It's more efficient to do all the work in a special, carefully written version of s t r s t r and avoid calling other functions altogether These sorts of problems are a common source of performance trouble-a routine or interface works well for the typical case, but performs poorly in an unusual case that happens to be central to the program at issue The existing s t r s t r was fine when both the pattern and the string were short and changed each call, but when the string is long and fixed, the overhead is prohibitive With this in mind, s t r s t r was rewritten to walk the pattern and message strings together looking for matches, without calling subroutines The resulting implementation has predictable behavior: it is slightly slower in some cases, but much faster in the spam filter and, most important, is never terrible To verify the new implementation's correctness and performance, a performance test suite was built This suite included not nly simple examples like searching for a word in a sentence, but also pathological cases such as looking for a pattern of a single x in a string of a thousand e's and a pattern of a thousand x's in a string of a single e, both of which can be handled badly by naive implementations Such extreme cases are a key part of performance evaluation The library was updated with the new s t r s t r and the sparn filter ran about 30% faster, a good payoff for rewriting a single routine Unfortunately, it was still too slow When solving problems, it's important to ask the right question Up to now, we've been asking for the fastest way to search for a textual pattern in a string But the real problem is to search for a large, fixed set of textual patterns in a long, variable string Put that way, s t r s t r is not so obviously the right solution The most effective way to make a program faster is to use a better algorithm With a clearer idea of the problem, it's time to think about what algorithm would work best The basic loop, f o r ( i = 0 ; i < npat; i++) i f (strstr(mesg, p a t [ i ] ) != NULL) return 1; scans down the message npat independent times; assuming it doesn't find any matches, it examines each byte of the message npat times, for a total of s t r l en (mesg) m p a t comparisons.

The ATM standard defines a full suite of communication rotocols, from the transport layer all the way down through the physical layer It uses packet switching with fixed length packets of 53 bytes In ATM jargon these packets are called cells Each cell has 5 bytes of header and 48 bytes of "payload" The fixed length cells and simple headers have facilitated high-speed switching ATM uses virtual circuits (VCs) In ATM jargon, virtual circuits are called virtual channels The ATM header includes a field for the virtual channel number, which is called the virtual channel identifier (VCI) in ATM jargon As discussed in Section 13, packet switches use the VCI to route cells towards their destinations; ATM switches also perform VCI translation ATM provides no retransmissions on a link-by-link basis If a switch detects an error in an ATM cell, it attempts to correct the error using error correcting codes If it cannot correct the error, it drops the cell and does not ask the preceding switch to retransmit the cell ATM provides congestion control on an end-to-end basis That is, the transmission of ATM cells is not directly regulated by the switches in times of congestion However, the network switches themselves do provide feedback to a sending end system to help it regulate its transmission rate when the network becomes congested ATM can run over just about any physical layer It often runs over fiber optics using the SONET standard at speeds of 15552 Mbps, 622 Mbps and higher.

The second-level subbands, namely s2LL [i, j], s2HL [i, j], s2LH [i, j], and s2HH [i, j], which represent the approximation, the horizontal detail, the vertical detail, and the diagonal detail subband, respectively are selected for the embedding. Because signature images are typically sparse images, the subbands s [i, j], with = {2LL, 2HL, 2LH, 2HH}, are then decomposed into blocks of PI PJ pixels in order to perform a local analysis and to identify the proper areas where the watermark has to be embedded. Two different embedding domains are then used, both derived from the Radon transform, as detailed in Section 20.3.1: The ridgelet [99] and the Radon-DCT domain. The selected blocks are projected in one of these two domains, and the most relevant projections coef cients are chosen. Dynamic features extracted from the acquired signatures are nally embedded in the signature image by means of quantization index modulation (QIM) watermarking [97] .

The first line is a program to be tested (everything after the word try) Each subsequent line is a set of inputs and the expected output, separated by tabs The first test says that if the first input field is 1 the output should be yes The first seven tests should all print yes and the last two tests should print no An Awk program (what else ) converts each test into a complete Awk program, then runs each input through it, and compares actual output to expected output; it reports only those cases where the answer is wrong Similar mechanisms are used to test the regular expression matching and substitution commands A little language for writing tests makes it easy to create a lot of them; using a program to write a program to test a program has high leverage ( 9 has more to say about little languages and the use of programs that write programs) Overall, there are about a thousand tests for Awk; the whole set can be run with a single command and if everything goes well, no output is produced Whenever a feature is added or a bug is fixed, new tests are added to verify correct operation Whenever the program is changed, even in a trivial way, the whole test suite is run; it takes only a few minutes It sometimes catches completely unexpected errors, and has saved the authors of Awk from public embarrassment many times What should you do when you discover an error If it was not found by an existing test, create a new test that does uncover the problen~ verify the test by running and it with the broken version of the code The error may suggest further tests or a whole new class of things to check Or perhaps it is possible to add defenses to the program that would catch the error internally Never throw away a test It can help you decide whether a bug report is valid or describes something already fixed Keep a ecord of bugs, changes, and fixes; it will help you identify old problems and fix new ones In most commercial programming shops such records are mandatory For your personal programming, they are a small investment that will pay off repeatedly.
