This data is useless, total pages online are meaningless, you have to count on the total alive domains with at least some pages, also other very useful data are how many domains with alive traffic, Top 1 million, 10 millions domains...

Some websites can find these data, include ahrefs.com

I think this site was trying to measure the size of the Google index, not necessarily the size of the entire web, despite the site name. The page talks about "Indexed Web" and "Indexed Dutch Web".

But their numbers still look wrong. Yep / Ahrefs claim to have indexed 100 Billion pages and reindex 8 Billion every day. While OpenWebSearch EU claim to have indexed over 9 Billion pages:

Please give us a way to buy this in China.

I don't fully understand the video, so what it is lacks compare with the original hardware?

I can't see any video links?

I can't even find the CS50 on it...I doubt the whole quality of this list.

Search for "computer science". I found several CS50...

Any real usage scenarios for this? I mean, can it be used as anti-filter or whatever things.

So is this possible that ISP or a country block this entire domain, and then you can't use the URL right?
