Overconfidence: Why You Suck At Making Development Time Estimates 297

Posted by Soulskill

Dan Milstein from Hut 8 Labs has written a lengthy post about why software developers often struggle to estimate the time required to implement their projects. Drawing on lessons from a book called Thinking Fast and Slow by Dan Kahneman, he explains how overconfidence frequently leads to underestimations of a project's complexity. Unfortunately, the nature of overconfidence makes it tough to compensate. Quoting: "Specifically, in many, many situations, the following three things hold true: 1- 'Expert' predictions about some future event are so completely unreliable as to be basically meaningless 2- Nonetheless, the experts in question are extremely confident about the accuracy of their predictions. 3- And, best of all: absolutely nothing seems to be able to diminish the confidence that experts feel. The last one is truly remarkable: even if experts try to honestly face evidence of their own past failures, even if they deeply understand this flaw in human cognition they will still feel a deep sense of confidence in the accuracy of their predictions. As Kahneman explains it, after telling an amazing story about his own failing on this front: 'The confidence you will experience in your future judgments will not be diminished by what you just read, even if you believe every word.'"

Dropcam CEO's Beef With Brogramming and Free Dinners 400

waderoush writes "Plenty of technology companies serve free breakfast, lunch, and dinner to their employees, but Dropcam CEO Greg Duffy says that's a form of mind control designed to get people to to work late. To keep employees happy, Duffy says, it's better to make them go home to their families for dinner. Some other suggestions from the San Francisco video monitoring startup: don't fill your engineering department with young, single, childless males (aka brogrammers). Keep your business model simple by making actual stuff that you can sell for a profit. And don't hire assholes. Why pay attention to Duffy's advice? Because Dropcam has a 100 percent employee retention rate — no one who has joined the 4-year-old company has ever left."

Peetke writes "As we all know Oracle is not the biggest friend to the Open Source Community. Long standing OSS supporter Wikipedia has now moved from an optimized fork of MySQL 5.1 to MariaDB 5.5, for both its English and German sites. Wikipedia expects all other languages to follow within a month. Performance-wise, this move has no big implications, but it will ensure our biggest community database will live long and prosper."
