Google Web History(New feature in google)

What is Google Web History

This free service remembers where you’ve been on the web when you’re logged into your Google account. You might think of Google web history as a password protected online audit trail of your web activity. Although it doesn’t store the page contents, it does grab the URL of pages you’ve visited along with a timestamp. If you’re accessing a secure page such as those with https://, your activity isn’t recorded. It also records your Google searches.
Although the web history can include your Google searches and visited pages this doesn’t mean it will record everything by default. There are some requirements. For Google to record web page visits, you need to install the Google toolbar for your browser and enable the Page Rank and Page Info option. Without the toolbar, only your searches will be saved.
Another variable is when you opened your Google account. By default, Google now enables this feature for new accounts. It’s possible you missed this text when you signed up.

How do I see my Google Web History

1. Go to http://www.google.com/
2. In the top right corner, look for the link My Account. You may need to Sign In first.
3. From your Google Account page, click Web History from the Services column on the right.
If Google has been capturing your data, you should see results like the screen snap below.
google-web-history-1

What Does Google Web History Show?

Like most Google products, the screen is nicely organized in thirds. The left column represents different Google properties you can scan or actions on your content. The middle section is the main area and provides the details. The far right provides a calendar if you wish to refine your content to a specific day.
The main content area depicts my web history for July 30th in chronological order. There are three types of items represented, which equate to the numbered markers.
Item 1 - An example of a Google search. I was searching for the Google toolbar for IE.
Item 2 - This is an example of a web page I visited that day. Since I’ve enabled Page Rank and Info with my Google toolbar, non-Google pages such as the Weather Underground page are logged.
Item 3 - This is an example of a bookmark as shown by the gold star. You can also add notes or labels to bookmarks for classification.

Acting on the Data

One nice feature of the service is that you can act on your stored data. You can use the search textbox to find a site you can’t remember. For example, while searching for a restaurant recently, I reviewed many online menus. Later, I needed to find which of the menus had a salmon entrée.
Google also does make the categorization easier with the links on the left side. An item to note is these side links relate to Google properties. As example, my visit to the New York Times site was not categorized as News. Only stories I read from Google News would show in this section.
Another feature that will appeal to people is being able to bookmark a page after the fact. How many times have you visited a site and forgot to note or bookmark it? With web history, you can mark an item at any time. Google provides a bookmark button at the bottom of each page. You can even export your bookmarks.

Building a Web Profile

In some regards, it’s great to be able to use someone else’s servers to store your web history and bookmarks. You’re not dependent on being on a specific computer. I can do research at my public library and see the information when I return home. It’s also nice that Google can leverage this data to make your future Google searches more relevant based on items I’ve viewed. Even the Trends section is interesting by spotting places you frequently visit or your top queries.
This personalization also raises concerns for people. There are plenty of people who dislike this tracking behavior. They don’t think anyone should track your web movements in this fashion whether it’s Google or their government. While Google has stated how they use the data and how it can benefit you, people still wonder what other inferences they might draw based on your activity. Certainly, they are not the first service to use previous transactions for recommendations, nor will they be the last. Just think of the number of online retailers that use past purchases for recommendations.

Stop the Data Capture & Erase Google Web History

Google has provided several options for people to remove data. You can easily check items and delete them from your web history. This is a useful feature around holidays where maybe you don’t want tracks left at online retailers. Of course, this really only applies if you didn’t log out of your Google account and someone knew how to access the page. There is also a feature where you can pause the service from your web history page.
At some point, you may decide you don’t want Google to retain your web history. If that’s the case, you can delete your data.
1. Go to http://www.google.com/
2. Sign into your account.
3. Click the My Account link in the top right.
4. Click the Edit link to the right of My services.
5. Click Delete Web History.
6. Read the warning on the page.
7. Check the box Yes, I want to permanently remove Web history from my Google account.
8. Enter your current Google password.
9. Click Remove Web History.

Types Of Viruses


                        Not all computer viruses behave, replicate, or infect the same way. There are several different categories of viruses and malware. Below I list and discuss some of the most common types of computer viruses.

Trojan Horse:
              A Trojan horse program has the appearance of having a useful and desired function. While it may advertise its activity after launching, this information is not apparent to the user beforehand. Secretly the program performs other, undesired functions. A Trojan Horse neither replicates nor copies itself, but causes damage or compromises the security of the computer. A Trojan Horse must be sent by someone or carried by another program and may arrive in the form of a joke program or software of some sort. The malicious functionality of a Trojan Horse may be anything undesirable for a computer user, including data destruction or compromising a system by providing a means for another computer to gain access, thus bypassing normal access controls.

Worms:
             A worm is a program that makes and facilitates the distribution of copies of itself; for example, from one disk drive to another, or by copying itself using email or another transport mechanism. The worm may do damage and compromise the security of the computer. It may arrive via exploitation of a system vulnerability or by clicking on an infected e-mail.

Boot sector Virus:
            A virus which attaches itself to the first part of the hard disk that is read by the computer upon bootup. These are normally spread by floppy disks.

Macro Virus:
           Macro viruses are viruses that use another application's macro programming language to distribute themselves.
They infect documents such as MS Word or MS Excel and are typically spread to other similar documents.

Memory Resident Viruses:
           Memory Resident Viruses reside in a computers volitale memory (RAM). They are initiated from a virus which runs on the computer and they stay in memory after it's initiating program closes.

Rootkit Virus:
          
A rootkit virus is an undetectable virus which attempts to allow someone to gain control of a computer system. The term rootkit comes from the linux administrator root user. These viruses are usually installed by trojans and are normally disguised as operating system files.

Polymorphic Viruses:
           A polymorphic virus not only replicates itself by creating multiple files of itself, but it also changes it's digital signature every time it replicates. This makes it difficult for less sophisticated antivirus software to detect.

Logic Bombs/Time Bombs:
            
These are viruses which are programmed to initiate at a specific date or when a specific event occurs. Some examples are a virus which deletes your photos on Halloween, or a virus which deletes a database table if a certain employee gets fired.

Invention uses human body as touchpad

                                   Think of it as a new form of body art. A PhD student at Carnegie Mellon University's Human-Computer Interaction Institute has created a new user interface for mobile devices that turns the human body into a touchpad. The idea is to use the technology as an input mechanism for mobile devices that are not big enough to include one.
The Borg-like technology, called "skinput," involves attaching acoustic sensors to the upper arm to pick up tiny vibrations created when fingers tap or flick across the skin's surface. A machine learning algorithm then interprets the input for forwarding to the target device.
The inventor, third year PhD student Chris Harrison, will present a paper on the technology at the Association for Computing Machinery's Human Factors in Computing Systems conference on April 12. Harrison released a YouTube video and information about the project last month.


The device, which Harrison envisions being worn like a wristwatch, would allow control of a projected keypad or other user interface displayed directly on the skin - or it could allow the wearer to control a basic device such as an MP3 player without a template, simply by tapping fingers, the inventor claims.
Harrison developed the prototype last year during an internship at Microsoft. Initial tests show the device to be about 88% accurate in interpreting inputs. But it does have limitations. It may not work so well on "heavier, fleshier people," the inventor says. And forget about using it in the gym: Running generates noise that degrades the signals.

What is NTN?

                The Network Terminal Tumber (NTN) is a set of digits that make up the full address of the end point to a data terminal. It is either a ten or eleven digit number found in the CCITT (International Telegraph and Telephone Consultative Committee) X.25 14-digit address.
The NTN is ten digits in length when it is not part of a national integrated numbering format. When it is part of a national integrated numbering format, it is eleven digits in length. In both cases, it follows the Data Network Identification Code (DNIC) in the CCITT X.25 14-digit address.

 NTN is also chat slang for "nothing."

What is Solenoid?

                          A solenoid can be a thin wire looped, or wrapped, around a metallic object. When electricity is passed through the wire, a magnetic field is generated. A solenoid can also be a transducer that converts energy in linear motion. It can be used as a switch to turn something on or off.
Computer motherboards contain solenoids and perform various functions. One important function is to help regulate the power coming from the power supply, in order to minimize the chance of voltage spikes and motherboard damage 

what is Blender?

                                   Blender is a 3D computer graphics software program for developing animated movies, visual effects, 3D games and software. Blender is an open source program, free to anyone for use. It offers many features including 3D modeling, texturing, rigging and skinning, fluid and smoke simulation, animation, rendering and video editing.
Blender was originally developed by NeoGeo and Not a Number Technologies in 1998 and was licensed as shareware. It is available for Microsoft Windows, Mac OS and Linux operating systems. It functions best on a computer having a 2 GHz dual or quad core processor, 8 to 16 GB RAM, an OpenGL, ATI FireGL or Nvidia Quadro video card with 1 GB RAM, and a monitor that supports 1920x1200 resolution and 24-bit color.

What is DTX?

                               DTX is a form factor for motherboards, a variation of the ATX form factor. It was originally developed by AMD in January 2007 and was designed for smaller computers like home theater PCs (media center computers). The physical dimensions of a DTX motherboard is 8.0 inches by 9.6 inches and the board allowed for 2 expansion slots. A somewhat smaller version was also developed, called the Mini-DTX, having dimensions of 8.0 inches by 6.7 inches.

The DTX form factor provided a lower cost of manufacturing, due to the fewer layers of printed circuit board wiring required to make the board. It was intended to be an industry standard for small form factor computers, like the Shuttle "SFF" design. DTX motherboards are backward compatible with the ATX form factor, fitting in computer cases designed for ATX motherboards. It also works with a standard power supply, requiring the same 24-pin power connector that the ATX motherboard requires.
