We have all been in projects where we use a combination of open source libraries, for different components of our architecture. We know theoretically that it should work, but alas, something blows up at runtime. If we’re lucky, we experience this on a weekly basis, but we don’t get lucky that often. The “Conundrum Solved” series will tackle some of these hair-pulling, sleep-depriving, grouch-inducing problems some of us at Summa have encountered in our projects. We hope that by sharing them with you, you’ll keep your hair, get enough sleep, and maintain a smile on your face!
