Generate website thumbnails and link-preview images from URLs with a screenshot API and Pillow. A tested Python script that batches five URLs per call, crops to three sizes, caches results and handles dead sites, plus the meta tags to use them.

A tested Python recipe for summarising long YouTube videos with any LLM - fetch timestamped segments, chunk without cutting captions, map-reduce the notes, and turn every cited time into a link that opens the video at that moment.
Why the Python youtube-transcript-api library works on your laptop but raises RequestBlocked or IpBlocked on AWS, GCP and serverless, which fixes actually work, and a tested fallback that only calls a hosted API when YouTube blocks you.
Enrich a lead list with public emails, phone numbers and LinkedIn/X links scraped from each company's own site, then rank the emails so you never write to the legal or privacy mailbox. Tested on real sites, including the messy results.
