Programmers with network engineering skills

Education in theoretical concepts is definitely a problem in general, 
but I've found it's particularly noticeable in the technology field 
which has become increasingly commercialized (or commoditized);  where 
once a "sysadmin" was a long-running process, grown from a person with 
the mindset of "how does this work?" and "let's build cool stuff!", 
eventually culminating in someone who knew operating systems, 
networking, and programming inside out (see: "UNIX greybeard" types), 
nowadays people haul off to a 5 day course in "Advanced System 
Administration(TM)", write a certificate exam or 15, and call themselves 
a "sysadmin".

There still are people with the "greybeard" mentality -- all of the very 
best sysadmins I know are of this type, and many know real programming 
(that is, data structures, algorithms, etc) better than the 
mass-produced developers our there -- but unfortunately, they're 
relatively rare, and usually very hard to recruit.   You have to have a 
very interesting project first and foremost -- salary is important, but 
building new, cool stuff is usually the #1 factor for top-notch 
generalists.
