[description], Story, any other text you want to use. Mamma.com: A Great Alternative To Google And Yahoo! by: Dean Phillips
In keeping with a promise I made to my readers, here's another great alternative to Google and Yahoo!: Say hello to Mamma.com! Mamma.com is a metasearch search engine. A metasearch search engine actually compiles search results from a variety of sources. When you enter a query at Mamma.com, you actually submit your query to the top search engines on the Internet, and then merge the results eliminating any duplicates. It searches Google, Business.com, Findwhat, About, LookSmart, MSN, Open Directory, plus other leading search engines. Mamma.com has a great power search page where users can choose the sources that they query. Since Mamma organizes between index, directory and pay-per-click, users can tailor the search engines to match the type of information they require. Mamma also have a great tool in its services and tools section that is called the Mamma explorer bar--click now, surf later. This lets users (who have downloaded the product) drag and drop search results into a window and save their search results for later viewing (or even just to make sure they don't lose track of the result). If you have ever done a search and come away with 10 open windows, you can easily imagine how useful this tool is for research. Mamma has a great ranking algorithm--applied to all pages returned. This gives back results that are both commercial in content and resourceful in terms of educating the user. Mamma also applies attribution to the search results--by default--sorting by relevance--not by source. On some other metasearch search engines, you have to go to the second page and do an extra click to get your results sorted by relevance. This is not optimal, since not one index is superior to the other, and sorting by Google first, may not always give the users the best result first. In addition, Mamma.com supports white and yellow page look- ups, and has a great picture search functionality. Here's an interesting note: According to Mamma.com, Mark Cuban, star of the reality television show, "The Benefactor," and owner of the Dallas Mavericks) invested in Mamma.com in March, because he liked the picture search functionality so much.
digital satellite tv
Until recently, people used a technique called symmetric key cryptography to secure information being transmitted across public networks in order to make digital satellite tv shopping more secure. This method involves encrypting and decrypting a digital satellite tv message using the same key, which must be known to both parties in order to keep it private. The key is passed from one party to the other in a separate transmission, making it vulnerable to being stolen as it is passed along. With public-key cryptography, separate keys are used to encrypt and decrypt a message, so that nothing but the encrypted message needs to be passed along. Each party in a digital satellite tv transaction has a *key pair* which consists of two keys with a particular relationship that allows one to encrypt a message that the other can decrypt. One of these keys is made publicly available and the other is a private key. A digital satellite tv order encrypted with a person's public key can't be decrypted with that same key, but can be decrypted with the private key that corresponds to it. If you sign a transaction with your bank using your private key, the bank can read it with your corresponding public key and know that only you could have sent it. This is the equivalent of a digital signature. While this takes the risk out of digital satellite tv transactions if can be quite fiddly. Our recommended provider listed below makes it all much simpler.
