How did this happen, and what security precautions/ lessons should I learn from this? htaccess file had been rewritten (copy and pasted below). I just got an email from a user that a website I administer "was down". Also thanks to everyones comments! Of course if you really want to get into this you should program one yourself but this is still a great list to start from if you just are getting into it. extract the (static) source code, then parse HTML, XML or JSON elementĮDIT- Added more to list.

Web Scraper Chrome (), a free Chrome extension which can be very usefull when scraping involves to browse a deep series of links. Outwit Hub (), regex based, relatively cheap (less than 100 $), but very powerfull If anyone has anymore I can add them to this list! Enjoy guys js rendering in the cloud, has a robust and well documented api If this is something you would be interested, let us know by upvoting, commenting, or both! My question is, how much interest is there in us open sourcing this crawler? I'm also thinking of writing a post about this on our blog, just detailing how it works. Here are the current stats of it running on a machine with 1 vCPU, 3.75GB of RAM, 1TB of disk space, running ~10 regular expression on 512KB of data or less: So, after spending a long time learning Go and doing some groundwork like Goque, we now have our own crawler built 100% in Go that meets these goals. Use the disk for the entire URL queue while remaining performant, so the only limitation of crawl reach is disk space (much cheaper than memory).Crawl billions of web pages on a single machine, with 1 (or more) CPUs, using only a few GB of memory.Perform a true BFS (Breadth-First Search) crawl of the web.
Gocrawl was another option and it's coded in Go, but it's suited more for depth-first crawls. Apache Nutch is widely known, but is complicated to set up and requires a crazy amount of disk space and memory, among other issues. Very recently too, I even tried using the popular Scrapy crawler, but it just didn't meet our goals. I've been reading about it for quite awhile now, seeing how others have solved the problem of performing extremely broad web crawls. Once we have all of them collected we can add it to the wiki/sidebar! I'll keep this post up to date as people comment to add new ones.Ī requirement of my new startup was eventually building our own web crawler.
