• Jeff Grigg: "I've always found it most entertaining when, from time to time, I've been able to fix a reported bug by doing NOTHING BUT delete lines of code. Yep; sometimes it does happen: The coders get so confused that we end up with useless complexity that does NOTHING BUT introduce bug(s). (I've found that it doesn't happen very often, but I find it entertaining when I see one." (XP@yahoogroups, 8/8/2008)

• Steve Freeman: "I've seen too many instances of groups that go 'Agile' (31 Flavours) without considering that this requires technical skills as well as index cards and donuts. If an organisation adopting Agile still treats design and coding as a junior stepping stone to more important jobs, then they are likely to see the 'Third-Iteration Crash' and prove the critics right."

• Esther Derby: "Teams need time to develop the social glue that enables high performance. They understand each other's strengths and weaknesses, develop shared knowledge, and discover how to learn together. When new people are constantly arriving and leaving, a group may never develop the shared approaches and shared knowledge that permit teams to outperform a group of individuals."

• Voltaire: "Doubt is uncomfortable, certainty is ridiculous."

• Ron Jeffries: "Software development is thinking work. It is unwise to imagine that we, no matter how smart we are, can do the thinking for a whole team, all day, every day. We need them to think for themselves. Therefore we need to behave in whatever ways are most helpful to them doing that."

• Nancy Van Schooenderwoert: "Defect rate is key for agile teams and I see a lot of Scrum implementations that have not paid enough attention to the agile technical practices (from XP) and so they struggle along spending significant time on bug-related activity, which makes it hard to complete the stories they've taken into their sprint." (posted on extremeprogramming@yahoogroups, 1/27/2008)

• Peter Alfvin: "Ironically, despite Scrum's focus on empirical process control, I think one of it's greatest strengths is that it's simple, prescriptive and well documented. It can be used 'off the shelf' and followed 'by the book' by relatively immature organizations to get the lean benefits of improved flow and continuous improvement and avoid some common management dysfunctions. As such, it's a nice stepping stone for organizations trying to start out with lean and agile." (posted on leanagilescrum@yahoogroups)

• M.A. Jackson: "The beginning of wisdom for a software engineer is to recognize the difference between getting a program to work, and getting it right. A program which does not work is undoubtedly wrong; but a program which does work is not necessarily right. It may still be wrong because it is hard to understand; or because it is hard to maintain as program requirements change; or because its structure is different from the structure of the problem; or because we cannot be sure that it does indeed work."

• Ilja Preuss: "Minimizing rework is work, too (for example, up front design). If taken to the extremes, it's very likely to be more work than the prevented rework. So what you will want to do is not minimizing rework, but finding a good balance. In my experience, the best rule of thumb is to prevent rework by not doing work that isn't yet absolutely needed to be done. Having to rework something because I've committed to it too early is one of the most costly things that can happen. Keeping my options open as long as possible, until I have as much information as possible, is the more effective strategy." (on agileprojectmanagement@yahoogroups)

• Ilja Preuss: "I can empathize with getting frustrated. Unfortunately I've found that it doesn't make me more effective. In fact I find that I am better at communicating and motivating when I'm rather emotionally detached from the results I'm getting. So now the best I can do when I get frustrated is to backtrack and talk to someone who isn't involved. Only when I'm no longer frustrated am I in a position to effectively coach/lead/influence the team again." (on scrumdevelopment@yahoogroups)

• William Pietri: "There's no rule against planning ahead in an agile process. There is a rule against stopping other work to plan.

Give him someone to ask for help when he's stuck, and his performance will improve even more. Give him a way to share in the sucesses of those around him and it will improve some more. And so on...."

There is nothing a mere scientist can say that will stand against the flood of a hundred million dollars. But there is one quality that cannot be purchased in this way---and that is reliability.

• Ron Jeffries: "As long as you always keep an open mind, that's what counts. That way you can be sure you don't hear things that aren't being said, and do hear what is being said. This third sentence suggests that the second sentence may be false and that the first sentence may offer a reason why."

• S. J. Gould, Wide Hats and Narrow Minds: "... But if we laugh with derision, we will never understand. Human intellectual capacity has not altered for thousands of years so far as we can tell. If intelligent people invested intense energy in issues that now seem foolish to us, then the failure lies in our understanding of their world, not in their distorted perceptions. Even the standard example of ancient nonsense -- the debate about angels on pinheads -- makes sense once you realize that theologians were not discussing whether five or eighteen would fit, but whether a pin could house a finite or an infinite number."

• T.H. White,The Once and Future King: "The best thing for being sad," replied Merlin, beginning to puff and blow, "is to learn something. That's the only thing that never fails. You may grow old and trembling in your anatomies, you may lie awake at night listening to the disorder of your veins, you may miss your only love, you may see the world about you devastated by evil lunatics, or know your honour trampled in the sewers of baser minds. There is only one thing for it then -- to learn. Learn why the world wags and what wags it. That is the only thing which the mind can never exhaust, never alienate, never be tortured by, never fear or distrust, and never dream of regretting. Learning is the only thing for you. Look what a lot of things there are to learn."

• William Safire's Rules for Writers: "Remember to never split an infinitive. The passive voice should never be used. Do not put statements in the negative form. Verbs have to agree with their subjects. Proofread carefully to see if you words out. If you reread your work, you can find on rereading a great deal of repetition can be avoided by rereading and editing. A writer must not shift your point of view. And don't start a sentence with a conjunction. (Remember, too, a preposition is a terrible word to end a sentence with.) Don't overuse exclamation marks!! Place pronouns as close as possible, especially in long sentences, as of 10 or more words, to their antecedents. Writing carefully, dangling participles must be avoided. If any word is improper at the end of a sentence, a linking verb is. Take the bull by the hand and avoid mixing metaphors. Avoid trendy locutions that sound flaky. Everyone should be careful to use a singular pronoun with singular nouns in their writing. Always pick on the correct idiom. The adverb always follows the verb. Last but not least, avoid cliches like the plague; seek viable alternatives."

• Stephen Hawking: tells the story of an elderly woman who confronted Bertrand Russell at the end of a lecture on orbital mechanics, claiming she had a theory superior to his. "We don't live on a ball revolving around the Sun," she said, "we live on a crust of earth on the back of a giant turtle." Wishing to humor the woman Russell asked, "And what does this turtle stand on?" "On the back of a second, still larger turtle," was her confident answer. "But what holds up the second turtle?" he persisted, now in a slightly exasperated tone. "It's no use, young man," the old woman replied, "it's turtles all the way down."
