Professional Development – What a Difference 60 Years Makes

Originally appearing at ForITPros.com. In 1957, the Soviet-made Sputnik streaked across the sky in low earth orbit. It was clearly visible to millions of concerned Americans. The Soviet government had leapfrogged America technologically. The dot that traversed the nighttime sky marked a change in international politics and fueled the engine that became America's space program. Another far more subtle shift was happening in America's businesses as well. In the 1950's and 1960's, American employees gave their loyalty to their employer in exchange for a commitment for a career-long job … [Read more...]

Professional Development – Set the Bar High

Originally appearing at ForITPros.com. Henry Ford is reported to have once said, “Whether you think you can or think you can’t - you’re right.” That’s great insight. Too often people place self-imposed and artificial limitations on themselves. They tell themselves that they cannot accomplish something because they aren’t smart enough or don’t have enough creativity. They close their minds to the idea they can, in fact, succeed. Success, after all, is scary to many people. As a leader, one of your jobs is to inspire your team. Help them to recognize and realize their potential. Don’t … [Read more...]

Professional Development – Interviews are a Two-way Street

(Originally appearing at ForITPros.com). I was recently chatting with a friend who was seeking advice about difficulties in their job. This was a job which, a year ago, she described as her dream job. It quickly became evident to her that it was actually a nightmare job. The company, her coworkers, and her boss were all dysfunctional in one or more ways and it was making her life miserable. One of her big questions was “What sort of questions could I have asked during the interview that would’ve helped me foresee what it’d actually be like to work there?” It’s Not Only About Pleasing the … [Read more...]

Originally appearing in my monthly column at Database Trends & Applications magazine. Delayed durability was announced late in the SQL Server 2014 development cycle, but offers something that many SQL Server professionals have wanted for years—the ability to disable transaction logging.

Professional Developement – Digging for Gold

Originally appearing at ForITPros.com. Andrew Carnegie, once the wealthiest man on earth, came from humble beginnings. As a young boy, he worked a number of odd jobs. His hard work, industrious nature, and persistence eventually led him to become the largest steel manufacturer in the United States. Once, during an interview, Carnegie was asked how he had hired 43 millionaires. At that time, being a millionaire was very uncommon. It would be similar to a person having $25 to $30 million in today's dollars. Carnegie was quick to correct the reporter. He had hired 43 people who had become … [Read more...]
