Familiarity? Not speaking for anyone else in this regard I shall
relate a short story.
When starting my first tech support job, I knew vaguely TCP/IP, some systemV type shell and
that I was jumping into the deep end into boiling water. Before starting I had asked
one of my similarly geeky (but more successful) school friends what I could do to get
up to speed, what are some more valuable skills to have. Two words and a gesture were all he
gave me, 'Learn perl' pointing to a tatty copy of the o'reilly 'perl in a nutshell'. This is in fact
the only paper perl reference I have ever owned, buying new edition on occasion. Why do I keep
buying the same one ? Familiarity. - that book saved my stressed out backside more time and frustration
that I can express. It was good advice then and I have clung to it.
As you say, this is not the forum for a trees vs electrons debate. I use both to the extent
that I LOVE having a solid reference on my desk, books smell good (!?) , I've never come across
a coffee ring on a perldoc -f page, but can reminisce about almost every abused
corner and tear of each of my copies of 'perl in a nutshell'. The perlers who can't believe
you don't have a copy of the Camel may have similar quirky feelings about that book - but who am I to speculate.
I can't believe it's not psellchecked
