Pointless update?

It is unreasonable to update.

I updated this blog for more than a month. Google like it when I update often. So I'm doing unnecessary update to find out what will Google do. Last year I started a blog, updates every two weeks and has been a great increase in search traffic from then (anecdotal evidence I know, but controlled experiments on SEO is difficult).

Now my updates are less frequent, my traffic sank a little again. So I was hoping that this update will cause my traffic again increase.

So it's not really unnecessary updates, it's part of an experiment to see how Google responds. And in fact I actually managed to get this feature into an interesting post on the search engines, so the experiment is apparently hopeless flawed. But read on, if you are interested in a waffle about how search engines such as Google actually operate.

We're talking about the search for signals, there are several different philosophy when it comes to search. At present, so search engines work is essentially a ' bag of words "approach. Which means, basically, are acting in a document, simply as a list of words without order or importance; "I'm a funny dog" is treated the same as "am I funny dog".

Search related documents is then just a matter of counting the number of words that match between the document and the search query. Some simple measures of assistance, such as the resulting asset stripping the last word, which includes. For example, the "complete" may be considered to be the "end" to match the ' End ', ' end ' and ' End ' all. You can see it in action on the Google results page, where highlights the words that are similar to those that you specified.

Word order in English is important, however, search engines and lose some of the information shozením order. Return some of this information, search engines also take the n-gram sub-phrases from the document, so rather than the simplistic bag of words, they are also a list of all sub-phrases contained in the document with the appropriate assistance. For example, if your document contains the following text: "I'm a funny dog," then the search engine internally may present this document as "dog", "I", "fun", "I", "I", "ridiculous", "funny dog". This representation was stripped of its bark stopwords, words that are so common they are very useful, such as "I" and "and", has emerged as "ridiculous" to "fun" and it's part of the bigram (two words) sentences, which means that it will rank better for "funny dog" than "the dog" – in both cases, the query consists of 2 words, which are present in the document, but using 2-gram phrase in an index, we can write the algorithm, which recognizes that "funny dog" is also in the document, so the query "funny dog" 3 hits in the index, while "dog" is just gets 2.

They told me that the 2009 Google has collected data 6-gram phrase for the entire web site, (it is quite a lot of data). These words may also be weighted according to their location within a document (towards the top in the title? as? the text link?).

Documents are also weighted according to their competence, calculated on how many sites link to your web site (known as PageRank). And another factor is the frequency of updates. Therefore, this update, only to find out what kind of impact it has.

Earlier I mentioned the different search philosophy, but I think it is probably a matter for a more detailed post with images, and code examples, and all kinds of actual content.

If your taste information for search engines was encouraged, but is not met, I recommend my boss podcast about how SEO is a modern myth.

Hide files in the files for better security of the data: using the program executable files to hide data with steganography

A new approach of AScienceDaily (May 9, 2011) to hide the data within the program files on a computer could make it nearly impossible to detect hidden documents, according to a report International Journal of Internet technology and secured.

Steganography is a form of security through obscurity information hidden inside the medium. An artist might paint a message encoded into a portrait, for instance, or author to embed lyrics in the text. Traditional paper watermark is an example of steganography is in action. At first glance, it appears that there is nothing unusual, but the recipient aware of the presence of hidden message can be extracted easily. In computer science, more than the art of steganography.

These target to hide information from prying eyes to embed data in many different file types that are ostensibly (mp3) of music, photos (jpeg), video (mpeg4) or word processing documents. Unfortunately, there is no limit to the amount of hidden data can be embedded in such files without this information becomes clear something is hidden because the file size increases beyond what can be expected for shared music or video file, for example. A music file to mp3 format in five minutes as the sampling rate of 128 kilobits per second, for example, is expected to be 5 megabytes in size. Much bigger aroused suspicions about the true nature of the file, a software mp3-tags in the open, something is wrong with the content of the file. This can be said for almost any other file types.

However, one set of files and their size, they are usually quite difficult to examine in detail that they provide compile computer code are the executable files or exe. These files tend to contain a lot of what might be described as "spam", as well as internal and programmer notes, redundant code snippets, some senses infuriatingly inflate code. All this adds up large file sizes and random fact for the .exe files. As such, it may be possible to embed and hiding large amounts of data in an encrypted file without disrupting the ability of the executed file, or run a program but ???????? without anyone discovering the file exe has a dual function.

Computer scientists Rajesh Kumar Tiwari of GLNA at Mathura, g., Sahoo of birla Institute of technology, Mesra, Ranchi, India, developed this algorithm for embedding hidden data in the session. They provide information International Journal of Internet technology and secured transactions. The algorithm built into the program with a graphical user interface will take the conventional exe file as input hidden data, merge the two producing sustainable exe file with the hidden content. The technology can be used on smart phones, tablet PCs, portable media players or any other information which a user may want to hide data.
