Compatibility issues with Dragnet
I am trying to work on a Python tool which makes use of Dragnet as a dependency. After quite a bit of issues I think I am starting to get a better picture that Dragnet will not be very easy to work with. The GitHub page says it was built for Python 2.7 “with recent support for Python 3”. The repo hasn’t been updated in 12 months; many of the other updates are from 3-4 years ago. A normal pip installation is not working. Their Issues page is full from posts from one year ago about various installation problems.

How does Firefox's Reader View work?
It's really nice that browsers offer reader modes, but they are frustratingly incomplete.
Really, let's switch to a user perspective once and consider - what if I always want reader mode? This is technologically complete impossible and all the solutions are a band-aid.
Firefox and others' attempts rely on the page authors' goodwill. But some pages will always attempt to frustrate reader modes.
Alternative approaches for content extraction use machine learning such as [1], but they of course need to be updated for culture- language- and technology-specific changes.
It's a mess and will remain so for the foreseeable future.

[Discussion] good html tokenization libraries?
You can take a look into how dragnet preprocess html block ( the Blockifier function ), it's certainly not the best since it collapse the tree structure into one sequential flow but I think is easier to work with once you know how to modify the code for your own need. While the hard way is use lxml and write the parsing yourself, which is also what's happening under dragnet.

Trafilatura: Python tool to gather text on the Web
The feature list answers that question pretty well: https://github.com/adbar/trafilatura#features
Basically: you could implement all of this on top of BeautifulSoup - polite crawling policies, sitemap and feed parsing, URL de-duplication, parallel processing, download queues, heuristics for extracting just the main article content, metadata extraction, language detection... but it would require writing an enormous amount of extra code.

Show HN: Build AI Dags with Memory; Run and Validate LLM Tools in Containers
The WebScraper tool uses Trafilatura [1] to scrape and parse HTML—nothing too fancy. "Scraping" a React site would require a totally different approach, probably something more akin to Adept's ACT-1 [2].
I run a local chat app built with Griptape and I use it to give me summaries of web pages or answer specific questions all the time :)

Powerful and free scraper with a headless browser under the hood and Readability for parsing
I've been playing with Trafilatura lately, and it's very good. There are a few very thorough comparisons to other projects and it really shines. It doesn't do anything headless from what I can tell, but it doesn't have to do the scraping itself. Maybe an option could be to use Playwright to scrape, then Trafilatura to parse. Food for thought.

I made a Chrome Extension that lets you ask any question about the page you are on (bluf.ai)
Cool! If you care to explain me further... :) ... I tried parsing a page using: https://github.com/adbar/trafilatura, json stringify it and passing it to https://platform.openai.com/docs/api-reference/embeddings/create. How do I use the response as an input later? <3
