How our young colleagues are being educated....

All networking courses SHOULD have some version of binary in them. Too
many things rely on it to be skipped. Yes, in the real world we have
shortcuts. But when those shortcuts become the only thing everyone knows,
bad things may be left to happen. Besides, if one can¹t do binary, how
can they be expected to understand hex?
Anyway Good these things are here, but one thing I will point out is
that there is a distinct difference with people glazing over because they
don¹t understand something versus the fact that something is truly boring.
There¹s nothing sexy about binary. But that doesn¹t mean it can¹t be fun!
So if the classes are Death by Powerpoint (which is very typical in
academia it seems), then I can certainly understand the aversion that
students would have to that.
Amazingly enough, for a skill that everyone SHOULD understand, I find a
tremendous number of people who don¹t. And for something that¹s boring
and nobody wants to learn, I have LOTS of people sign up for various
sessions I do at certain vendor¹s trade shows on that very subject. So
someplace there¹s a disparity in there.
Now, as a side, one problem that I often have with various academic-based
courses is that the people who teach them often don¹t have enough
real-world experience (or not current anyway) in order to pass along any
benefit in that matter. There are many things that need to be addressed
at this level within the higher-education arena, and I¹m sure it¹s not
just related to networking subjects!
