Debugging pdf epub mobi txt 电子书 下载 2025

This book was born in 1981 when a group of test technicians at Gould asked me if I could write a

document on how to troubleshoot our hardware products. I was at a loss—the products were boards

with hundreds of chips on them, several microprocessors, and numerous communications buses. I

knew there was no magical recipe; they would just have to learn how to debug things. I discussed

this with Mike Bromberg, a long time mentor of mine, and we decided the least we could do was

write up some general rules of debugging. The Ten Debugging Commandments were the result, a

single sheet of brief rules for debugging which quickly appeared on the wall above the test benches.

Over the years, this list was compressed by one rule and generalized to software and systems, but

it remains the core of this book. So to Mike, and to the floor techs who expressed the need, thanks.

Over the years, I've had the pleasure of working for and with a number of inspirational people who

helped me develop both my debugging skills and my sense of humor. I'd like to recognize Doug

Currie, Scott Ross, Glen Dash, Dick Morley, Mike Greenberg, Cos Fricano, John Aylesworth (one of

the original techs), Bob DeSimone, and Warren Bayek for making challenging work a lot of fun. I

should also mention three teachers who expected excellence and made learning enjoyable: Nick

Menutti (it ain't the Nobel Prize, but here's your good word), Ray Fields, and Professor Francis F.

Lee. And while I never met them, their books have made a huge difference in my writing career:

William Strunk Jr. and E. B. White (The Elements of Style), and Jeff Herman and Deborah Adams

(Write the Perfect Book Proposal).

To the Delt Dawgs, my summer softball team of 28 years and counting, thanks for the reviews and networking help. I'm indebted to Charlie Seddon, who gave me a detailed review with many helpful

comments, and to Bob Siedensticker, who did that and also gave me war stories, topic suggestions,

and advice on the publishing biz. Several people, most of whom I did not know personally at the

time, reviewed the book and sent me nice letters of endorsement, which helped get it published.

Warren Bayek and Charlie Seddon (mentioned above), Dick Riley, Bob Oakes, Dave Miller, and

Professor Terry Simkin: thank you for your time and words of encouragement.

I'm grateful to the Sesame Workshop, Tom and Ray Magliozzi (Click and Clack of Car Talk—or is it

Clack and Click?), and Steve Martin for giving me permission to use their stories and jokes; to Sir

Arthur Conan Doyle for creating Sherlock Holmes and having him make so many apropos

comments; and to Seymour Friedel, Bob McIlvaine, and my brother Tom Agans for relating interesting war stories. And for giving me the examples I needed both to discover the rules and to

demonstrate them, thanks to all the war story participants, both heroes and fools (you know who

you are).

Working with my editors at Amacom has been a wonderful and enlightening experience. To Jacquie

Flynn and Jim Bessent, thank you for your enthusiasm and great advice. And to the designers and

other creative hands in the process, nice work; it came out great.

Special appreciation goes to my agent, Jodie Rhodes, for taking a chance on a first−time author

with an offbeat approach to an unfamiliar subject. You know your markets, and it shows.

For their support, encouragement, and countless favors large and small, a special thanks to my

in−laws, Dick and Joan Blagbrough. To my daughters, Jen and Liz, hugs and kisses for being fun

and believing in me. (Also for letting me have a shot at the computer in the evenings between

high−scoring games and instant messenger sessions.)

And finally, my eternal love and gratitude to my wife Gail, for encouraging me to turn the rules into a

book, for getting me started on finding an agent, for giving me the time and space to write, and for

proofreading numerous drafts that I wouldn't dare show anyone else. You can light up a chandelier

with a vacuum cleaner, but you light up my life all by yourself.
