  • Perplexity (an “AI search engine” company with 500 million in funding) can’t bypass cloudflare’s anti-bot checks. For each search Perplexity scrapes the top results and summarizes them for the user. Cloudflare intentionally blocks perplexity’s scrapers because they ignore robots.txt and mimic real users to get around cloudflare’s blocking features. Perplexity argues that their scraping is acceptable because it’s user initiated.

    Personally I think cloudflare is in the right here. The scraped sites get 0 revenue from Perplexity searches (unless the user decides to go through the sources section and click the links) and Perplexity’s scraping is unnecessarily traffic intensive since they don’t cache the scraped data.









  • My solution:

    The outer square lines in the third column/row is the result of the difference between what exists in the first two items in that row/column. Only outer lines appearing only once will be in the 3rd shape. The center lines seem to be only center lines that appear in both shapes. Therefore x is 52, since all outer shapes cancel and there are no shared center lines. The rest is fairly simple.

    The second derivative of f(x) is 78x + 22, so the answer is 78(52) + 22 + 52 = 4130

    I’m not completely confident in this solution but it seems to be consistent with the known columns and rows.
