View Your Google Histroy

Did you know that Google has been keeping track of every single Google search you’ve ever performed? That is, at least every Google search you’ve performed while logged in to your Google account. Don’t believe me? 

Go here:https://www.google.com/history


Neat, huh? You can browse through your web history (includes searches and sites visited) by date using the calendar on the right, and beneath it is the total amount of searches you've performed to date. I’m nearing 50,000. I don’t know whether to be proud of or depressed by that.

In case you’re wondering if this is a breach of privacy, it’s not. You agreed to this when you signed up for a Google account. And you signed up for a Google account when you started using Gmail, YouTube, Picasa, Google Docs, Google Voice, Google Talk, Google Desktop, Google Sites, Blogger, Google Reader, Orkut, Google Code, iGoogle, Google Chrome—you get the point. There’s a lot of stuff that’s owned by Google and signing up for any of it signs you up for Google Web History as well.

Personally, I don’t mind it. I think it’s kind of interesting.


Google Trends
You should also check out the Trends section, which works just like Google Trends but only for you. The All Timesetting isn’t particularly insightful, since it could span back for years, but if you limit it to the last year, last 30 days or last 7 days, things get interesting. Apparently, I spend most of my time googling groovyPost, instead of spending the extra millisecond to just tack on the .com. (I think in the biz they call that a “navigational search.”) And unsurprisingly, the site that I visit the most is a Bandcamp page that just streams white noise (puts my baby to sleep, works like a charm).




The graphs along the bottom confirm other facts about your search habits that should be obvious. For instance, I do a lot more googling on the weekdays than the weekends. And I googled the least in July, when I was traveling most of the month.




Other Considerations

  • This is different and distinct from the history that’s saved in your browser. Browser history is saved locally on your machine. Google Web History is saved on Google’s servers and applies to all activity done while logged in on any device. So, for example, if you performed a search on your iPhone, it would show up here as well. If you want to remove all traces of your web history, you’ll have to delete your Google Web History and your local browser history.
  • When you are in Incognito Mode, you are not logged in to your Google Account, thus your search activity / web browsing activity won’t be recorded in Google Web History.
  • Google uses your web history to tailor your search results and ads. So, if you are testing your search engine rankings or just want to see the web like the rest of the world sees it, search in Incognito Mode.
  • If you have Javascript disabled or some other “no scripts” plugin installed, Google Web History may not work.
  • If you install the Google Toolbar, Google will begin tracking sites that you visit even if you don’t go there directly from Google.com.

What is VoIP and SIP


In telecommunications, VoIP (Voice over Internet Protocol) is the new buzzword as many companies and individuals try to take advantage of the cost savings it offers. Another new term connected with VoIP is SIP (Session Initiation Protocol) due to the appearance of many SIP phones. The main difference between SIP and VoIP is their scope. VoIP is actually not a discrete technology but a family of technologies that are primarily concerned with setting up voice calls across packet networks like the Internet. SIP is just one of the technologies that are under the VoIP umbrella.

There are many technologies used in VoIP. There are technologies that are used to convert and compress the audio signal; there are technologies that are used to format the digital data and transmit it to the destination, and there are technologies that are used by devices to communicate with each other. SIP is in the latest of the three. It is a protocol that standardizes signals to initiate, terminate, accept, reject, hold, or redirect VoIP calls. It is basically a language used by the phones in order to communicate what it wants to do with each other. SIP is not concerned with how the voices are carried across the network once the call has been initiated as other protocols are used for that.

What confuses most users is the difference between VoIP handsets and SIP handsets. Keep in mind that a SIP handset is also a VoIP handset. The products that are commonly called VoIP phones require to be connected to a computer, and the computer has to be turned on in order to conduct calls. It is not very desirable to have a computer running just so you can make and receive calls. SIP phones are able to do the signaling without the need for a computer. It can, therefore, be plugged into an Ethernet outlet and connected to the Internet. In this scenario, only your modem needs to be constantly powered to give the SIP phone access to the Internet. In this manner, SIP phones behave more like traditional phones.

Google Chrome OS


As if its decided lead in spiders, searches, and engines is not enough, Google launches its new Chrome OS, the company’s browser-based operating system. The new OS offers marked differences in data handling, such as cloud data storage, adding more user security and ease of use. It is also a very light operating system and does not eat up a lot of RAM. This is ideal for netbooks and systems that rely on cloud computing. Being a by-product of the Chrome browser, the Chrome OS also boasts of similar security features that the browser has been known for.

How it works


Security is one of the key components in the Chrome OS. The system fuses typical system-level security systems with exploit mitigation techniques. Thus, it successfully decreases the venues for attack and the system codes that can be attacked by malicious programs. And because all applications run through the browser, the operating system is more compact and easier to control and protect.

Sandboxing has been crucial in how Chrome functions. Through sandboxing, processes and applications have minimal interactions with each other and the operating system kernel. This partitioning of processes and applications makes it difficult for any malicious attacks to affect the whole system. Crashes become seldom, if these occur at all.

Security


Security is also one of the trademarks of the Chrome OS. Contrary to current trends in operating systems, Chrome limits the ability of applications to download and run any binary. This minimizes any application compromises that open up the whole system to attacks.


 
Likewise, the Chrome OS boasts of a verified boot process. This boot process allows the system to start up and boot without possible harm to the system’s memory, the Linux kernel, and the partition tables. This is done through cryptography.


Since the whole Chrome OS is secured by Google, it is close to impossible for any malicious program to penetrate and run. And even when some freak malicious programs do manage to get through the doubly secured kernel hardening and processing infrastructure, this will be immediately detected upon reboot. This sends a prompt to the user. It also initiates self-cleaning program within the system.

The cleaning process has less hassle too than the others. Since the system data is set apart from the user data, the system can fix itself without causing the user any setting changes and lost data. Cached data is also kept intact, within the “cloud” of Google servers. Adding to user specification security, the user data within the browser, OS , and plug-ins are encrypted. Devices cannot share user data.

For any bugs found upon installation, the Chrome OS has set up an auto system update and patch. All this is done in the background, even while the user keeps on working online.

Now, that makes for a lot of exciting new stuff from a technology company that’s been very reliable and attentive to its users.

Verizon Wireless and Intuit Form Mobile Payment Partnership


 Verizon Wireless and small business software provider Intuit announced that the two companies would be partnering to provide mobile payment services through Intuit’s GoPayment system. Intuit’s mobile payment device and application will be offered in Verizon Wireless’ stores and marketed directly to small businesses through Verizon Wireless’ business-to-business channels.

Intuit’s GoPayment card reader is compatible with most smartphones and tablet devices, plugging into the device’s audio jack. The device is being marketed to small businesses and merchants that lose sales opportunities when they have to turn down payment by credit card. “GoPayment is meeting a huge need and is one of the fastest growing mobile payment solutions in the market,” Chris Hylen, general manager of Intuit’s Payment Solutions Division, says in a press release. “With Verizon Wireless, we’ll help even more people discover that they too can process credit card payments on the phones or tablets they already own.”

WHAT IS VIRUS? WHAT IS THE DIFFERENCE BETWEEN VIRUS,WORM,TROJAN AND SPYWARE ?


    We all have heard the terms Virus,Worms,trojans and spyware but only a few of us know the difference between them.We genreally consider everything that is detected by an antivirus as virus but this is not the case.The antivirus not only provides protection against viruses but it also protects us from trojans,worms and spywares.All these can be harmful to your computer hardware and software.Today I will differentiate all these terms from each other .
 

Ok lets start from the introduction of viruses

Virus:- A virus is a self replicating program that attaches itself to an executable file.When the file is executed the virus automatically gets executed and enters into system memory .Once it enters into system memory it either searches for other files that can be infected or stays in the background and infect the files that are uses the virus infected program.

Worms:- Worms are very similar to viruses but differ in way that they donot bind themselves to executable files instead to replicate themselves they uses the network .If you find excessive use of your network bandwidth then you may be infected by a worm.So,a worm donot require a user to execute any file for its execution it can work without user intervention.

Trojan Horse:- A trojan horse is harmful program which may seem harmless to the user before its installation but instead it is programmed or reverse engineered to facilitate unauthorised remote access to the computer.Trojan’s donot replicate themselves.

Spyware:- A spyware is a program that secretly monitors and collects pieces of information.They usually run in stealth mode and cannot be detected easily .Keyloggers is a great example of spyware software.There are not limited to just spying but can also send data to remote computers.
