In general I would concur with you.

But of course, someone who knows/expects that his audience knows can trancend and use it to his advantage.

In this case I'm fully with derby.

The subject of "DOS" seems too good a shrewd choice. It will trigger the foe identification of some and pitying commentaries from others. On the other hand it's also old-fashioned enough that unless you want to admit/pretend that you learnt nothing in the last at least 15 years, noone will challenge you on your expertise on this subject either.
Nearly two decades ago I had a co-worker who really was a DOS-guru, meaning he knew his Int21 table by heart. But such a person would not act today as if he had been in a state of suspended animation since that times.

Update: On a completely different note: I wonder how the OP of this thread can be hit #3 in a Google search for "Kevin Raymer" since robots.txt here forbids all spidering?!

Interesting - it may not have been actually spidered, but just indexed from offsite links to it? Google doesn't show a snippet of the text, and has the title slightly wrong.

I'm looking for a job.

I'm sorry if my cynicism offends anyone, but

Never attribute to stupidity that which can be adequately explained by malice.
