Google.com , everybody knows about this site. This is an American public corporation which main source of revenue is online advertising. If anybody asked which service of google is most popular then without any confusion you can answer google search engine.
Actually now-a-days if we need any information’s, any songs ,topics then we search in google. Its very interesting that
how google search a huge database and give relatively desire output with in a second.
In addition to providing easy access to billions of web pages, Google has many special features to help you to find exactly what we’re looking for. An important feature is Google Cache.
Now before discuss about google cache lets see about cache. What is Cache?
Actually Cache is a process of data or information backup where original data or information source is expensive to fetch and will kill time. Once the data is stored in the cache, in future we can use that data with out refetching original data which will consume our average access time.
Now what about Google Cache ? Google takes a snapshot of each page it examines and caches (stores) that version as a back-up. The cached version is what Google uses to judge if a page is a good match for our query. Google indexes a page (adds it to its index and caches it) frequently if the page is popular (has a high PageRank) and if the page is updated regularly. The new cached version replaces any previous cached versions of the page. Users can access the cached version by choosing the “Cached” link on the search results page.
A few days ago I have faced a peculiar problem. My homepage, which was http://www.engr-faisal.co.cc. I have converted that site in XHTML and change site URL in www.engr-faisal.co.nr. And older site has closed and the link is not available. But it still showing in google cache. So, this little bit bothering me. So, for preventing this type of problem we can follow ………
To prevent all search engines from showing a “Cached” link for your site, place this tag in the section of your page:
<meta name=”robots” content=”noarchive”>
To allow other search engines to show a “Cached” link, preventing only Google from displaying one, use the following tag:
<meta name=”googlebot” content=”noarchive”>
but this tag only removes the “Cached” link for the page. Google will continue to index the page and display a snippet.
To remove a page or image, you must do one of the following:
- Ensure requests for the page return an HTTP status code of either 404 or 410 OR
- Ensure that the pages you want to remove have been blocked using a robots.txt file OR
- Ensure that the pages you want to remove have been blocked using a meta noindex tag.
This month Adobe released Adobe Flash Player 64-bit for Linux. At last, people can watch song, game, internet video on 64-bit Linux desktop and laptop, just like all of my 32-bit.
What’s really interesting is that this is Adobe’s first 64-bit release of Flash. That is, Linux users got it first, before users of Windows Vista x64 and and MacOS X. It probably does not mean anything, especially since Adobe has mentioned 64-bit flash will be released at the same time across platforms, but you can’t help but feel good inside.
Those who use Adobe Flex don’t need to worry at all. Flex-3, the new version of Flex was designed to work with Flash Player 9. Now all Flex-created content will continue to function as expected with Flash Player 10. To build Flex content that takes advantage of the new features, developers will need the latest Flex SDK daily builds, which support export to SWF 10.
Update: Some quick notes…
The tarball provided on the labs website is not the conventional Adobe Flash installer–it just contains the plugin. To use the plugin, drop the .so file into your ~/.mozilla/plugins/ directory.
Make sure to uninstall your npviewer-powered 32-bit Flash completely (disabling the plugin within Firefox is not enough).
