Say I want to learn QT Programming, machine learning libraries, etc. I am not aiming for <i>deep</i> understanding at the get go, but I want to get usable output quickly, as I dig deeper.<p>What tricks have you learned over the years which enable you to get productive in a new framework quickly?
One thing that helps is choosing a technology you already know to achieve the learning you desire.<p>For example, if you want to learn Qt, and you know only C++, don't bother with Python. It will help you focus on the framework 100%. Machine learning, albeit a different beast, can be tackled the same way.<p>Start small with the things that you can quickly learn and understand and then move to more advanced topics.
