My limited experience with graphical programming is that of using LabView for a test set that a customer requested, rather than my usual programming language of choice. I am not a big fan of graphical programming although I know a lot of folks are - I do get concerned because I think that "you can focus on engineering/design concepts, instead of teaching a programming language" may be a good start for getting young people interested - but if you don't learn a programming language, you sacrifice the ability to have low level control when you need it.
As manufacturers add new technologies to their products, designing for compliance becomes more difficult. Prepare for the certification testing process. Otherwise, you increase the risk of discovering a safety issue after a product leaves the assembly line. That will cause significant time-to-market delays, be much costlier to fix, and damage your brand in the eyes of customers.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
