Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- uTLS – Go TLS fork with low-level access to ClientHello for mimicry purposes

Show HN: Golang HTTP Clients and Servers and Alternative Networking
Does this offer any control at the TLS level? I have been looking for alternate TLS stacks for Go, and the only one I really found was uTLS:
-
Easiest way to MITM my browser requests/responses using Go
Something that you'll run into for smarter anti-bot is that your JA3 tls signature will be checked. Easiest way to get around this is probably to use refraction-networking/utls. Especially true as go's tls signature is fairly unique.
-
GET request works only from the browser
Considering that the rocket league api isn't one of tracker.gg's listed apis, they probably enabled a lot of cloudflare'e antibot. If you really care to get around it, you can probably get fairly far with making sure you put the same headers as the chrome version you're trying to mimic. If that still doesn't work, then theres a chance that tracker.gg enabled ja3 fingerprint so you'd need to use a library like utls to fake your clienthello to look like chrome's.

ClientHello mimicking in Rust
do we have something like https://github.com/refraction-networking/utls but for rust?

Modest: A fast HTML renderer implemented as a pure C99 library
Project is deprecated in favour of the same developer's lexbor project[0].
-
Created a performance-focused HTML5 parser for Ruby, trying to be API-compatible with Nokogiri
It supports both CSS selectors and XPath like Nokogiri, but with separate engines - parsing and CSS engine by Lexbor, XPath engine by libxml2. (Nokogiri internally converts CSS selectors to XPath syntax, and uses XPath engine for all searches).

Andreas Kling (of SerenityOS fame) is building a new Linux browser using SerenityOS libraries
An HTML parser, probably the simplest relatively modern example I could find is 1MB https://github.com/lexbor/lexbor (haven't used it, but might look more into it now that I know it exists.)

Lazyweb link: https://github.com/rushter/selectolax
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

Libraries for retrivieng html data from website

What second language to learn after Python?
Well, regarding HTML5, what I've found was libxml (does not support tag-soup HTML5), https://github.com/lexbor/lexbor, for which I was unable to find good documentation ( see https://lexbor.com/docs/lexbor/#dom), Apache Xerces (appears to not support tag-soup HTML5 as well), and Gumbo, which does not appear to be active and to support selectors and XPath (although there are libraries that add that).

You can't parse [X]HTML with regex
I think we've all (mostly?) tried it. It really is the Wild West of the web when you're trying to parse other people's HTML, though.
I've played around with this parser which is extremely quick. https://github.com/lexbor/lexbor

How SerpApi sped up data extraction from HTML from 3s to 800ms (or How to profile and optimize Ruby code and C extension)
I’m glad to have the opportunity to contribute to an open-source project that is used by thousands of people. Hopefully, we will speed up Nokogiri (or XML parser it uses) to match the performance of html5ever or lexbor at some point in the future. 800 ms to extract data from HTML is still too much.
