Nokia e63 review
This is my blog post after a long while, also this post comes from my new nokia e63. I bought this after I reviewed lot of mobile phones. First of all, I have an aversion for touch phones because it gets finger print all over the screen and its not accurate while I message while walking. I tried a few touch phones. So I settled for a qwerty phone. It is an entry level smart phone that is from nokia in an attempt to get a share of enterprise mobile market. I'm not a heavy user of camera also, this 2MP would do fine for me. Also, I needed wifi for internet access from home. One more advantage is that e63 has a 3.5mm audio jack which makes it compatible with all speakers at home. But why not nokia e71. it has 3.5G which has not arrived in India. 3.2MP which is not of use for me. It's got a metal body which is .3mm less thicker than nokia e63 and it hardly makes a difference. Most of all nokia e71. Comes with an additional 6000INR, why would I pay for little features that hardly matter. E63 has everything same as nokia e71 except the above mentioned ones. There's one more in the same range blackberry curve 8520 unlocked. It has everything that e63 has but no 3g and additional 4k. Nokia e63 a purchase worth the money. Dedicated music keys are missing. Symbian os makes life all easy with lot of softwares already available.

Many mobile operating systems around? Friday, July 31, 2009

Mac os x modified for iphone, android, nokia's open source os, mobilin, limo. And now the chrome os, i wonder why google would make it a new os rather than Android on net books. When there are many choices around it is a healthy environment for vendors due to competition but it leaves customers wonder what to choose.

Eminem Relapse 2009 Tuesday, June 23, 2009

Eminem Relapse is Marshall Mather's recent Rap album produced by Dr. Dre. Emimen is no stranger to being on top music. Sold 650,000 in first week, its big hit this year. Relapse is Marshall's reflection on his recent past four years, a skit in this album where emimen says about where he had gone in the last years and his drug problems, addiction and a song following it.

One reason why relapse is a hit is that, he's got a story to tell. His own story which adds a human touch to the album, unlike other staged music albums listening to this one feels like Eminem. I like the Beautiful song. Never let anyone say you aint beautiful is the message, where how being a celebrity feels like and how he wants to be a normal person is spoken about. Its my favourite one too.

Rap has a lot of critics and controversy, but it continues to grow in popularity. Young souls like it a lot.

How Google detects invalid clicks Monday, June 22, 2009

If you had landed on this page venturing how google detects invalid clicks, you are at the right place. The mechanism Google uses is as good and efficient as its search and its well mature at this point of time I would say. Because a lot of people tried to make more money by cheating Google, they took all this input to formulate their secret formula to detect invalid clicks. Adsense is one program which earns google a lot of revenue. Here are some things that I think they would take into account to detect invalid clicks. If you are a web master or a user of Google analytics, you'll know this better.

IP Address - If you are connected to Internet you are assigned an individual ip address and if you've noticed carefully and most consumer Internet connections are assigned dynamic ip address and each time you connect to the Internet you have a different ip address based on a scheduling by your isp. If Google can track you by ip address one might think why not disconnect and connect again to get a different ip address. Clever boy! but never forget, its the same isp and you are given ip within a range allotted to your isp. No matter how many times you disconnect and connect to the Internet you will remain in the same range which lets google know that the click is coming from the same range. Now they raise their eye brows and the following factors will let them detect that it is the same user.

Cookies - If you enter any web site with Google ads, they put a cookie into your browser and if it expires only after a year or so. Unless you delete it, its got an unique identifier to identify when was the cookie planted and that's how they identify you uniquely. Repeated clicks from the user having same cookie is just the most dumb way of getting caught. If you delete the cookie from browse each time before browsing, Google knows the click is coming from a new user all the time, when it detects invalid clicks. Got it? There is no way to cheat Google, unless you are a Internet expert or junkie who cheated for a long time, or possibly got caught many times.

Click Patterns - When one does click on own ads, they tend to click only theirs not other ads or not on other sites. which is a really different behaviour from ordinary. When one intends to make invalid clicks they click and try to run away from the site. Moving on to click on another ad. This behaviour could be tracked. Google knows how much of time a genuine visitor spends on a target site linked from ad. Technically this is called bounce rate.

CTR - Google has the statistics of how much CTR does a visitor from search engine would produce.

CTR from Google side - A well performing ad will have good CTR. If one tries to cheat Google, its for sure they might click a non performing ads in a row. which alerts them.

Mac addr - This is the hardware address of your Ethernet card. I'm sure packets flowing a network use this for a lot of purposes including authentication to enter a network in case of corporations. In other case, it may not be the case, stuff like dial up does not have a Ethernet mac address.

Traffic sources - If a site is new or a site penalized by google for illegal content, it probably does not have traffic from search results. When such sites have high traffic, this is something that they might count on.

Location Geo Tracking - With your ip address, Google can target ads to a particular city or even a small town. The same is used to detect invalid clicks. They can easily know where you are located. Its also easy to use proxy site, unfortunately proxy sites are a outdated way of making such invalid clicks, one could easily get caught. The next dumb way of getting caught is using proxy. They have a list of all proxy servers across the world. I need not give a reason for you to believe that.

There are a lot of other factors that Google knows about a particular user like

  1. Network speed and latency
  2. Your screen resolution
  3. Google user's web history
  4. Surfing patterns
  5. A site's user patterns
  6. Points where one user clicks on screen
  7. Points on site where a normal user clicks

Possibly a hybrid artificial intelligence algorithm learning and predicting about users and traffic behaviour on web. We'll never know it. We'll never know if Google uses it for invalid click detection or not. It is impossible to cheat Google's systems. Also, any violation of adsense TOS will also be detected easily.
