Creating favicon with GIMP software

      Sites or blogs on the Internet generally have a favicon, an image / icon as a sign of site or blog. Favicon will appear with the title of the site in the address bar. It’s also used on a site bookmark. This will make it easy to identify a site or blog from the image / icon.

       Image / icon that is used as the favicon should be square (16x16) with “.ico” file extensions. How to make a favicon? Create a favicon is actually not too difficult. Favicon can be made using Photoshop software from Adobe, but this software (originally) quite expensive. Favicon can also be created using free software like GIMP, an alternative solution for photoshop. The software can be obtained free of charge from the Internet (just ask google, where to download it!)

        This time I will try to explain step by step, how to make a favicon with GIMP software. First , of course you must already have the GIMP software installed on your computer. Open/run the software, then click "File", then "new". Enter the size of the image : "width" = 16 and "height" = 16 pixels (16x16), then click "OK". On the displaying window will visible a square that according to the size of the image that we will create. To facilitate the work or the design icon that we created, we can enlarge the window size. Click view select Zoom 8:1 (800%), or more, it is up to you. Then you can start creating images that will be used as a favicon inside that square field. Once the design is finished, It is just need to save the favicon. Click "File" then "save as". In the window that appears, than type the name of the icon with the extension. Ico, or click the "Select file type (by extension)" and select "Microsoft Windows icon." (Ico) and then click "save". Your favicon was done and It can be put on your site or blog. Put or create a favicon to a blog on blogspot (Blogger) now is also quite easy.

Computer

       At the earlier time, Computer was refer to human computer, a man that which the job was count or do arithmetic calculations, with or without assistive devices.

       Along with the changing times, people start trying to develop tools to perform arithmetic calculations that are considered to be quite difficult. Starting from simple tools such as the abacus evolved into mechanical/electrical tool, which then become more dominant in the calculation job which was later named computer.

       So the computer was originally a calculating machine. The work done with computers almost always associated with problems of arithmetic. But then the computer use for many tasks and occupations, not just those related to mathematics alone. Computers are now used in almost every field of work. Development of Internet technology is also increasingly expanding use of computers.

       By the time, definition of computer as a calculating machine is no longer appropriate given to today's modern computers. Computers today can be interpret as the equipment used to process data into specific information, according to the procedure have been formulated. Such data may include numbers, letters or words and the resulting information can be signed articles, graphics etc. Another definition from Wikipedia: a Computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations.

The service is fully legitimate and has nothing to do with spam, but it offers free subdomain names and only charges for bulk orders. This free services has attracted a ton of unwanted attention.It’s been so popular that a big chunk of spam originates from this domain.

         If you have a site/sites with co.cc subdomain, they won’t show up in Google search results. Even that you’ll still be able to access them, it will deeply decrease your site traffic because traffics usually com from search engine. While Google was known as the most popular search engine, it will have a big effect on your site traffics.
