(Apache Nutch is a Java-based web crawler which supports e.g. CommonCrawl (which backs various foundational LLMs)) https://en.wikipedia.org/wiki/Apache_Nutch#Search_engines_bu... . But extruct extracts more types of metadata and data than Nutch AFAIU: https://github.com/scrapinghub/extruct )

although I don't follow the need to have what appears to be two completely separate HTML parsing C libraries as dependencies; seeing this in the readme for Modest gives me the shivers because lxml has _seen some shit_

> Modest is a fast HTML renderer implemented as a pure C99 library with no outside dependencies.

although its other dep seems much more cognizant about the HTML5 standard, for whatever that's worth: https://github.com/lexbor/lexbor#lexbor

Heh, oh, new to the Internet, are you? :-D

What do you do when your Python program is using too much memory? How do you find the spots in your code with memory allocation, especially in large chunks? It turns out that there is not usually an easy answer to these question, but a number of tools exist that can help you figure out where your code is allocating memory. In this article, I’m going to focus on one of them, memory_profiler.
