Does anyone have the courage to perform a similar inspection on the Cloudflare homepage like the author did? On my M4 Mac mini, Safari lagged with single-digit frames per second (FPS), which scared me so much that I had to close the page as quickly as possible.

It's good to have a client side that does not send data to remote, improvements:

- CSP and security headers, currently this site scores D on https://securityheaders.com

- no SRI check on CSS or JavaScript files.

- by loading adsbygoogle.js which invalidates any privacy protection claims.

I have previously written a blog post on this very topic, tl;dr: deleting your keys.

I also think OAuth could be used to better serve AX in the age of agent, but before the whole industry find the PMF, shall we not leave the humans (us) behind? Thus I made one for breaking the grip of big IdPs and offer a more secure and easier authentication solutions for humans [1].

You can find its dogfooding demo on the Show HN [2].

In case one not digging into the source code, the key stretching here is PBKDF2-HMAC-SHA512 with 400,000 iterations (OWASP recommended 210,000).

The reason for not using Argon2 or scrypt is because PBKDF2 is native provide by Webcrypto yet FIPS-140 compliance.

The very ticket [1] is locked by this epic ending:

> You were overly confident in your opinion, but I hope this website helps you understand that it's actually really damn hard.

> The reason your program shows a high FPS under other terminal emulators is simply, because their rendering pipeline works independent of VT ingestion. Gnome Terminal is not laying out text faster than your display refresh rate either. And of course, again, this is something WT will probably do as well in the future... but this project is nowhere near as old as Gnome Terminal is.
