Not sure, how many of you are aware. But this exists from the era of the bygones and the site is still active. Go take a look at http://www.perlmonks.org/ The whole site is a treasure, an extremely precious treasure of programming wealth. I've learned more from Perl Monks than from any book out there.

Some day that database will super valuable. It still is. Sometimes I get this idea that once could crawl that site, extract all the useful information and convert it into a neat book.

All the best, and Happy writing Perl one-liners, its an art of converting days worth work into a few seconds. I haven't read this book, but it definitely must be awesome. As with anything with Perl, it always is.

Before all this big data fad caught on, I used to write Perl one liners to solve most problems in 10% the time and probably 1% of the resources, for nearly most cases of what people call big data today.

As I found many times, Perl is awesome until you encounter someone else's Perl.

I inherited a Perl CGI and MySQL monster back in 2002 from a Perl monk who unfortunately died. It was a horrific Cthulu-inspired sprawling demon from hell. Little did I know, this is the norm until my third wave of inherited Perl a few years later.

Larger things now push me to Python and I get enough mileage on the smaller things out of the shell and sed/grep/awk. If I want fast stuff, it's a speedup module for Python in C.

I think back fondly of it but I know at the same time it hurt me.

I was once that "someone else" - I once left a many-thousand line script behind me which consisted of hundreds of undocumented (and very similar in many cases) regexes and not one instance of the word 'sub'. "It just sort of grew like that", "I was young, a novice!" I tell myself, but still jerk awake in a cold sweat from time to time after fevered dreams of 30 levels of conditional nesting.

My last gig where I took over for "someone else", a fairly new system which still managed to have "legacy issues", I understood the gravity of my crime. I tried to atone by crafting concise, readable nuggets for my successor but I am still haunted.

I met the chap who took over from me recently. Regarding my "someone else" he asked: "How did you maintain your sanity?" "I didn't". He also complimented the parts I left behind, but I still have those restless nights.

"Someone else"'s worst crimes were committed using Ruby on Rails, but the Perl system was constrained by an existing, strongly defined framework. With absolute freedom, there's no telling what damage "someone else" may have wrought.

Oddly, the most horrific Cthulu-inspired sprawling demon from hell I've ever inherited was actually written in python.

I guess a sufficient level of disinterest in maintainability can defeat any language designer's hopes for the future.

perlmonks is definitely the thing which most impressed me about perl. Very helpful, kind, patient and incredibly knowledgeable people there. I don't really have anything useful to say, I just want to thank anyone that's been a part of that community - they've certainly helped me out immensely.
