Recently I had come across one problem related to 301 redirection. We need to permanently redirect few URLs on one of the web site to new set of URLs. We also need to implement solution for this issue in such a way that search engine should also acknowledge these changes. I mean the redirection should be search friendly so that search engine should maintain page rank for these URLs.

Are the days for CDs, DVDs, Zip drives over? A computer whizkid is revolutionizing the computer data storage through his Rainbow Technology.

A student has developed a technique for portable data whereby the data can now be stored on ordinary paper. And to boot, larger amount of data can be had on lesser space. The immediate question that pops up in the mind is how to retrieve the data. Will it be as facile as feeding a floppy disc or CD into the drive and having it on the monitor? Perhaps it will be much easier than all that. The piece of paper or even plastic sheet storing the data has just to be scanned in the scanner and read over the monitor.

Named as 'Rainbow Technology', the new technique is the brainchild of Sainul Abideen, who has just finished his MCA from MES Engineering College in Kuttipuram in Kerala's Malappuram district.
