Hi All--

Thanks so much for all your advise and encouragement. I think I'll work on using my 2nd edition of Programming Perl as a jump start and reference while topping up my skills with several of the references mentioned.

I look forward to posting more questions to the board as I learn!

    I like dead trees, so I went from Learning Perl to The Perl Cookbook to Learning Perl(4th) with a detour through Cross-Platform GUI Programminng with wxWidgets(wxPerl). I also read most of the Perl Monks posts on a daily basis to broaden my vision of what is out "there". From this I know I need to spend more time with split, join, map, grep, and regexs. Some of that stuff looks like whistling into an acoustic coupler! I like to learn from reading good code as has already been mentioned.

[Corion]: Meh. I have a very simple mechanism to scrape+track prices, and even to send me mail if something changes (via cron), but SQLite doesn't support window functions, so my simple SQL to determine a price change won't work :-( Maybe I should store the DB ...
[Corion]: ... in Pg, but that would mean that I'd have to deal with credentials and stuff :)
[Corion]: In fact, the whole thing is just four simple programs, one App::scrape, another being DBIx::RunSQL, and one some glue to convert a JSON object into an SQL INSERT statement (+DBI connect/execute), so it would be an incredibly simple solution...
[Corion]: ... but that simplicity falls down due to SQLite letting me down and me being too lazy to move to a real DB. Maybe DBD::CSV can handle window functions...
[hippo]: Pg has the "trust" mechanism if you don't fancy using credentials for a trivial db.
[Corion]: hippo: Oooh, that sounds quite nice - let me read the documentation on that :)
[hippo]: https://www. postgresql.org/ docs/current/ static/auth- methods.html#AUTH- TRUST
[erix]: or compile & run an instance as yourself (not user 'postgres')
