There is a highly relevant follow-up post by the author here, too: https://byroot.github.io/ruby/performance/2025/01/23/io-inst...

It's really just focused on a keto diet, but using the app at https://www.carbmanager.com you can look up low-carb foods really well and enter units in all kinds of ways. I know someone who successfully used it for about 2 months a while ago, but then they went off keto and the app DB didn't have many non-carb heavy foods.

Maybe it's marketing, but there seem to be some advances [1]

Are you indicating that Cloudflare's implementation isn't truly fully post quantum secure because of lagging certificate standards/technology?

Wanted to provide the source for your posting about 33% of Cloudflare TLS traffic having Post-Quantum Encryption as of Jan 2025 [1]

Hmmm. This solution still leaves quite a few days a compromised certificate can be used(!).. that's significant.. but I guess it's better than nothing?

I thought you were joking and I laughed, but then I read the article and it says "It also holds more than half the volume of Lake Tahoe".. hmmm..

What is addressed recently by NIST, Cloudflare, Google, Apple, and others primarily involves potential(?) weaknesses in TLS key exchange & asymmetric cryptography. Let's Encrypt is more about certificates, I think, no?

During a Google podcast below[1] a host (reportedly with a PhD in Quantum Mechanics) expressed a similar opinion as you at first, then started to take the threat more seriously as he heard from an experienced Google colleague.. This was in 2024 before the Google Willow announcement[2]. Thank you for your thoughtful response!

I just asked the question because I wonder if getting more responsive/agile to security protocol updates should become more of a norm. Why not start as an example of that here if it doesn't take much cost/time/effort? For whatever reason it doesn't seem like just security theater. NIST, Google, Apple, and others seem to be taking this admittedly unknown threat seriously. It's good to balance skepticism with curiosity here I think (the podcast episode below agrees). The certainty of this happening anytime soon is publicly unknown of course, but if in the rare chance it happens, even within a decade or two, the consequences could be serious. Apparently it was Richard Feynman, perhaps amongst others who raised the question regarding quantum computers according to this interesting Google podcast. During the podcast a host reportedly with an apparent PhD in Quantum Mechanics started to take it more seriously.. Thank you for your thoughtful response! https://cloud.withgoogle.com/cloudsecurity/podcast/ep164-qua...

lol. Maybe so! :).. but is NIST? Is Cloudflare? Is Google/Apple?

>Genuinely don't know why anyone would use it when you have perplexity, gemini, chatGPT search, etc. at your disposal.

LLMs hallucinate/confabulate. I use Wikipedia to check source info and to find additional information. Of course there are more reliable sources than Wikipedia, but it's useful, still.
