I can’t shut up about the last task I did for one of my former customers: I made a script that scraped our own app’s invoice pages and printed all the scraped pages to PDF. It also utilized parallel so several downloads and PDF creations were happening at the same time.
The whole script, with good comments included, is no more than 45 or so lines yet it was one of the most productive scripts I have ever written. Our business people – who wanted the PDF invoices – were thrilled.
