WHAT IS SEARCH ENGINE CRAWLER?

Image
A  search engine crawler   is a program or automated script that browses the World Wide Web in a methodical manner in order to provide up to date data to the particular search engine. While search engine crawlers go by many different names, such as web spiders and automatic indexers, the job of the search engine crawler is still the same. The process of web crawling involves a set of website URLs that need to be visited, called seeds, and then the search engine crawler visits each web page and identifies all the hyperlinks on the page, adding them to the list of places to crawl. URLs from this list are re-visited occasionally according to the policies in place for the search engine. The policies of the search engine can be different for each search engine, and may be a cautionary action to ensure that some of the pages that have been added to the index before have not become spam. Search engine crawlers have a hard times crawling the web on occasion because the Interne...

Why should you reverse-engineer the brain? Great thing about the Reverse engineering While some of thinking machines have mastered specific narrow skills — playing chess, for instance — general-purpose artificial intelligence (AI) has remained elusive. Part of the problem, some experts now believe, is that artificial brains have been designed without much attention to real ones. Pioneers of artificial intelligence approached thinking the way that aeronautical engineers approached flying without much learning from birds. It has turned out, though, that the secrets about how living brains work may offer the best guide to engineering the artificial variety. Discovering those secrets by reverse-engineering the brain promises enormous opportunities for reproducing intelligence the way assembly lines spit out cars or computers. Figuring out how the brain works will offer rewards beyond building smarter computers. Advances gained from studying the brain may in return pay dividen...

Bill Gates’s father was a lawyer. A very successful one. His mother a teacher. Reading business magazines in middle school, Bill Jr. had a different dream – to open a company. You could say that’s how he started – with a childish dream. Many kids have dreams, though. How was he different? How Bill Gates  Started To Hack Next, Bill Gates saw a computer at 13. The school he went to bought one machine and a teletype. He paid for the time to use it. When money ran out, he hacked into the computer to use it for free. Then he got banned by the school. Then the school realized he had a rare skill so they asked him to use the computer and help them find bugs. He started to be a hacker. Bill Gates believes he can improve the way he thinks in general. He suggests and himself practices “brain rules” from the eponymous book by John Medina. The rules explain how the brain works from musical memory to the ability to play baseball. Since this is an infographic blog, I shoul...
