How Do You Prove Software Testing Saves Money? 312

cdman52 writes "I work at a small software development company. We have one app that is used by a few hundred clients and was initially developed by a few undergrads about 10 years ago. The app is collection of about 25 developers preferences and ideas. Testing wasn't an initial concern since it was created as an internal application, I guess. Anyway, the app is now large and used frequently. Part of my duties are to fix bugs users find, I'm on a team with a few other people and at least once every 2-3 months I see some bug I fixed come back, and I can only assume it's because we don't have a formal test suite. The owner doesn't want to invest time or money in getting one set up, but I'm sure that in the long run it would save time and money. Can anyone offer suggestions for how to convince the owner that setting up a test suite is in his own best interest?"

Why Published Research Findings Are Often False 453

Hugh Pickens writes "Jonah Lehrer has an interesting article in the New Yorker reporting that all sorts of well-established, multiply confirmed findings in science have started to look increasingly uncertain as they cannot be replicated. This phenomenon doesn't yet have an official name, but it's occurring across a wide range of fields, from psychology to ecology and in the field of medicine, the phenomenon seems extremely widespread, affecting not only anti-psychotics but also therapies ranging from cardiac stents to Vitamin E and antidepressants. 'One of my mentors told me that my real mistake was trying to replicate my work,' says researcher Jonathon Schooler. 'He told me doing that was just setting myself up for disappointment.' For many scientists, the effect is especially troubling because of what it exposes about the scientific process. 'If replication is what separates the rigor of science from the squishiness of pseudoscience, where do we put all these rigorously validated findings that can no longer be proved?' writes Lehrer. 'Which results should we believe?' Francis Bacon, the early-modern philosopher and pioneer of the scientific method, once declared that experiments were essential, because they allowed us to 'put nature to the question' but it now appears that nature often gives us different answers. According to John Ioannidis, author of Why Most Published Research Findings Are False, the main problem is that too many researchers engage in what he calls 'significance chasing,' or finding ways to interpret the data so that it passes the statistical test of significance—the ninety-five-per-cent boundary invented by Ronald Fisher. 'The scientists are so eager to pass this magical test that they start playing around with the numbers, trying to find anything that seems worthy,'"

St. Louis Museum Offers Thrills, Chills, and Lawsuits 140

theodp writes "Despite the whiff of danger, or perhaps because of it, the WSJ reports that the City Museum is one of St. Louis's most popular attractions. Housed in a 10-story brick building, the City Museum shows none of the restraint or quiet typical of most museums. It boasts a five-story jungle gym with two real-life jets kids can climb on, an enclosed Monster Slide that drops riders the length of three staircases, and a rooftop Ferris wheel. Sure, there are the occasional severed fingers and skull fractures, but museum founder Bob Cassilly contends that it is as safe as it can be without being a bore. 'They [lawyers] are taking the fun out of life,' says Cassilly, adding that 'when you have millions of people do something, something's going to happen no matter what you do.'"

Yes. Having the degree gets you past the HR check. They don't care where the degree is from. They only care about the check mark for degree on "meets the posted job requirements" so the resume can be passed on to the person actually making the hiring decision. If they have even the slightest bit of common sense, the person making the decision is going to be far more interested in the interview and what knowledge you can demonstrate than which college shows up on a piece of paper.
