Article: Agile Development: why it rocks, who it helps, and why it's failing
Agile development is all the rage now. This great article explains that one of the key reasons for the early success (and now the frequent failure) of agile is that its originators, like those of most anything new, were using the “startup” mentality (mostly as consultants). Thus, anyone who takes an entrepreneurial approach to process improvement is likely to succeed, regardless of the details.
Article: Why Pair Programming Works
Most developers have at least a passing familiarity with pair programming. But, even if they are convinced about it, it’s usually a tough sell to management. This author points out six specific advantages of pair programming, including continuous code review, less time trying to figure out problems during coding, reduced distractions, and built-in training/backup capability.
Article: Object Orientation (and other poorly understood idioms)
While this article is probably more properly labeled a rant, it does bring out some good points about the practice of software development versus the theory of computer science (which was the topic of an article referenced in the July 2009 newsletter).
Article: Software Engineering: Dead?
Jeff Atwood discusses the shocking conclusion of long-time (and very respected) pundit Tom DeMarco that software engineering needs to be abandoned and the focus should be on the practice of software craftsmanship.
Article: Maker's Schedule, Manager's Schedule
Paul Graham presents a very strong argument about the importance of developers having dedicated time, usually in blocks of 4 hours or more, to do their work and that incessant meetings are a significant and detrimental distraction. This type of uninterrupted time is important in most any creative discipline.
Article: Is Technology Killing The Corporation?
Computers are a ubiquitous tool in all companies now. But some new research shows that technology is failing to deliver on all of its promises, especially for small business, such as ROA decrease of 75% since 1965. Interestingly, while we often hear about how IT fails to support the business (the so-called “IT-business alignment” problem), one of the findings is that many corporate cultures cannot adapt to new, disruptive technologies.
Article: Agile teams: Focus on the people rather than the process
The specifics in this article shouldn’t come as a surprise to anyone: people over process (one of the core tenets of the Agile Manifesto, by the way!). But it doesn’t hurt to be reminded once in a while. And remember that agile adoption, especially in larger organizations, is not always easy.
Article: Forgotten Refactorings
This author points out that without a good process for refactoring and understanding your specific purpose for refactoring all you end up doing is rearranging the deck chairs on the Titanic (although his language is a little stronger!).
Article: Agile In a Flash
To the uninitiated, agile development methodologies often seem like magic (or bunk!). A couple of agile experts want to change that with some virtual flashcards (flashcards are one of the hallmarks of many agile methodologies) that teach agile principles.
Article: Project Metrics for Software Development
Management loves metrics! Everyone knows that; in fact, it might even be their mantra. Nevertheless, the article presents some useful and simple metrics to measure the progress and outcomes of development projects, with a decidedly agile focus.
Article: No to SQL? Anti-database movement gains steam
The push to move away from enterprise RDMBS (called noSQL) is picking up momentum including backing from industry giants like Amazon and Google. This is happening for a variety of reasons, especially scalability problems with RDBMS and they are applied in situations where they shouldn’t be. They suggest so-called “key-value stores” like Hadoop and Voldemort as alternatives and some hybrids like Cassandra and BigTable and one company has shared their experience with making the switch. I’m not sure how this will work out (of course, there are those that dismiss the idea and here), but it’s probably a trend to watch and something that developers need to start getting familiar with (like parallel and concurrent computing).
Article: Top Five Causes of Poor Software Quality
What’s your guess about this commentator’s #1 reason for low quality software? Bad process/methodology? Insufficient requirements? Wrong! He says that the major cause is lack of understanding of the business domain.
Article: Software Testing Paradoxes
“In God we trust; all others must bring data,” (famous quote from quality pioneer W. Edwards Deming) might be the mantra of software testers. However, as this article aptly shows, sometimes the data itself isn’t the whole story when it comes to assessing software quality.
Article: Visa card surprise: $23,148,855,308,184,500
By now, you’ve probably heard about this glitch (or ‘programming error’), but it’s a good example of the importance and value of testing and of how domain knowledge by testers is so important. Slashdot reports that the problem was due to how the amounts were stored. And, by the way, to put $23 quadrillion in perspective, the combined annual GDP of all of the countries in the world is around $60 trillion (here’s $1 trillion in perspective) or about 0.25% of $23 quadrillion.
Article: Sacrificing Quality Costs More Than You Think
This is an interesting perspective on the question: Should quality be compromised? When? The author emphasizes that letting quality slip on one release often results in a psychological effect that quality can be further sacrificed later.
Article: The Psychology of Software Testing
Successful testing requires the proper mindset and attitude. This comprehensive article discusses the mental preparation for testing and how to avoid “test anxiety”.
Article: Six Tools For Testing Designs On Mobile Devices

Article: Job Interview Questions You Need to Know
Preparation is the key to a successful interview. Here are some new questions that candidates are likely to face in technical interviews in the 21st century.
Article: The surprising benefits of time pressure at work
We frequently feature articles about how multitasking doesn’t work (at least not for sentient humans). Now, a researcher has shown the counterintuitive result that completing a predecessor task only prevents interference with subsequent tasks if the first task was completed under time pressure. The result is apparently due to the subtle confidence-building effect of completing the first task under pressure.

Article: Schmoozing 101: Tips for shy techies
Most people know that networking (the social kind, not the technical kind!) is important for career development and often for finding your next position. But if you’re introverted or just plain shy, schmoozing (for some reason that word sounds “dirty”!) might feel like getting a tooth pulled. Here are some tips for a low-key approach to networking.
Article: The Words You Wear
Here we get an education about some of the new, “fashionable” buzzwords making the rounds in IT and business circles. But the author’s main points are that we need to look past the words and grasp the concepts and ideas that others are presenting before we make a judgment and that each group has “rules” that regulate it.

Article: Memristor minds: The future of artificial intelligence
Article: For Best Results, Forget the Bonus
This classic essay, based on research from social psychology, says that offering bonuses and other reward incentives, instead of just regular pay, actually have the counter-intuitive effect of reducing productivity. Some of the reasons are that it doesn’t address causes, only effects, and that it undermines the personal motivators that workers have which are inherently more powerful than financial or other external rewards. Perhaps this is a strong argument for abolishing work.
Article: Antitrust: Apple and AT&T in DOJ’s sights
According to a report in the Wall Street Journal, the Department of Justice is looking into whether AT&T and Verizon, which together control 90% of the U.S.’s landlines and 60% of its 270 million wireless subscribers, have becoming monopolies with their recent acquisitions. The probe is likely to look into the exclusive iPhone distribution rights of AT&T.

US broadband Internet access growth has slowed from 8.5 million new subscribers in 2007. Broadband accounts for a total of 67.7 million subscribers with cable companies slightly outpacing telecoms (36.9 million to 30.7 million).
Article: Analyst warns of multiple-technology substitution
A telecom analyst says that technology is reaching the point where the “landline-or-VOIP” question is transitioning to where multiple technologies can be considered, which lowers the barriers to entry for consumers. This goes along with the predictions that the number of residential landlines by 2011 will be less than half the count in 2005.
