Quotable Quotes

Perseverance is not a long race; it is many races one after another.  –Walter Elliot

Optimism is a revolutionary act.  –Cameron Crowe

To dare is to lose one's footing momentarily. To not dare is to lose oneself.  –Soren Kierkegaard

The greatest way to live with honor in this world is to be what we pretend to be.  –Socrates

When ideas fail, words come in very handy.  –Johann Wolfgang von Goethe

Plato is my friend—Aristotle is my friend—but my greatest friend is truth.  –Isaac Newton

The weakest living creature, by concentrating his powers on a single object, can accomplish something. The strongest, by dispensing his over many, may fail to accomplish anything. The drop, by continually falling, bores its passage through the hardest rock. The hasty torrent rushes over it with hideous uproar, and leaves no trace behind.  –Thomas Carlyle

Impatience never commanded success.  –Edwin H. Chapin

The successful person makes a habit of doing what the failing person doesn’t like to do.  –Thomas Edison

Software Development Process and Methodology

Article:  Law of Averages Overturned

A Stanford professor says that project managers need to bone up on their statistics and apply principles of probability to estimation and project planning.  He notes that small deviations in actuals from estimates in project schedules are the main reason for development project “failure”.

Articles:  Low Tech Approaches to Requirements

As technologists and purveyors of technologies, developers often first turn to the computer for requirements-gathering and documenting tools.  In this three-part series, a programmer suggests some decidedly low-tech approaches that are often more efficient and effective.  Sometimes, good old pencil and paper and a sit-down conversation with the users is the best technique.

Article:  Developer's Kvetch: The Rotting Stink of Corporate IT

This author opines about the sad state of corporate IT shops, such as disregard for standards, apathy, and the frustration with “the process”.  But she also notes that corporate IT can work, especially who small, empowered teams are used.

Article:  Stand Back and Deliver: Introduction to Key Principles

In many ways, IT project management is more art than science.  This book excerpt discusses the main ideas behind “good agile” practice both from the IT and business perspectives.

http://www.informit.com/articles/article.aspx?p=1355310

 

Article:  Do Not Use Design Patterns Upfront

This author claims that design patterns should not be used during initial development, because, at that point, they are essentially a solution in search of a problem.  Instead, he suggests that patterns should be part of the refactoring phase and flow from the initial code.

Software Testing & Quality

Article:  The Surprising Right Fit for Software Testing

While autism-spectrum disorders like Asperger’s syndrome are often seen as a handicap to IT professionals, this article indicates that such behavioral differences may be the factor that sets successful testers apart from developers.  And here’s a personal story about Asperger’s syndrome from a career tester.

Article:  Automated Software Testing Distilled – Standards and other Considerations as Prerequisites to Success

Many people (frequently those without test backgrounds) see automated software testing (AST) as the panacea for testing faster and with fewer people.  However, AST itself requires careful analysis for suitability and organizations need to remember to AST involves a development lifecycle itself.

Article:  SQLite: A Lesson In Low-Defect Software

This article provides an in-depth analysis of how SQLite went from “quick hack” project to a high-quality ubiquitous application.  (You know that it’s the database engine behind the history, bookmarking, and other data management functions in Firefox web browser, right?)  The key aspects are liberal use of comments in code, extensive code coverage for unit tests, and process improvement, all of which are techniques that any developer or project can adopt.  One of the points that most stuck out to me is:  Safety != Reliability. Safety: no harm; reliability: no failures.

Tutorials/References

Reference:  langref.org

Patterns are a great tool to use to learn a new programming language.  This site uses the pattern concept to show how to solve common programming programs in a variety of languages, including Java, PHP, Perl, C++, Python, Ruby, and more.  One of the best features of the site is that it gives you the ability to compare an implementation in a language that you already know to one that you are learning, so you can see the differences and subtleties.

Career Development/Miscellaneous

Article:  Why goofing off boosts productivity

While this one is certain to be controversial, some new research indicates that those who take breaks that most would consider "slacking" actually are more productive.  In  particular, those that spend time on non-work-related web surfing are 9% more productive.

Article:  Want to get ahead? Sleep in

In bad news for me, new research via brain imaging shows that later risers have more mental stamina and can outperform early birds.  After 10 hours of being awake, the early birds showed reduced activity in brain areas linked to attention span, compared with the night owls.  And night owls tend to be wealthier, as well.  So much for Ben Franklin’s maxim:  Early to bed, early to rise makes a man healthy, wealthy, and wise.

Article:  The scientific method

In this succinct article Seth Godin suggests the best way to improve and “get smarter” is to use the scientific method.  He says that rather than being defensive, we should enter conversations looking for something to test, measure, and then change.  The concept is very similar to Deming’s Plan-Do-Check-Act cycle for improvement.

Article:  Why Smart People Do Stupid Things

New studies have found that intelligence does not imply the ability to think rationally.  This article discusses dysrationalia (my new favorite word!) and how you can improve your rational thinking.  One researcher even suggests development of tests to measure RQ (“rationality quotient”) similar to IQ.  As well, self-discipline is a greater predictor of performance than IQ.

Article:  The problem with PowerPoint

On the occasion of the 25th anniversary of PowerPoint (can you believe it?!), the BBC reports on how these types of presentations are not effective.  For example, PowerPoint makes us “dumb” by hiding relevant facts and often the presentations are just too boring (“PowerPoint poisioning” or “death by Powerpoint”) and the audience overlooks relevant information.
