  • Google Cloud fraud defense, the next evolution of reCAPTCHA
    How though? Can you also avoid DDoS simply by designing your system to not care if the requester is a bot or not. Let's say I'm running https://grep.app/ for example. AI bots start heavily using it, costing me a ton of money. How would you magically design this so it doesn't matter if the end bots are using it? - Source: Hacker News / about 2 months ago
  • Ask HN: Little or even unknown website that you like to use?
    Https://grep.app - To search repos for patterns. I usually use it when I'm using an obscure or badly documented library. https://unicode.scarfboy.com/ - Unicode stuff. There are a lot of small Unicode tool sites. - Source: Hacker News / over 1 year ago

  • Sourcegraph Went Dark
    Https://grep.app/ is another good one. Not sure how many repos they index though. - Source: Hacker News / almost 2 years ago
  • Code Finder โ€“ The ultimate search engine for GitHub repositories
    Https://grep.app/ is similar and seems to return results, but I have not compared it to native GitHub search. - Source: Hacker News / about 2 years ago
