The Web would not be so simpler and interactive without Ajax. This technology makes Web applications pleasant, interactive, quick responsive and light weight. Take any of the online map applications, no matter whether it is Yahoo Maps, Google Maps or Windows Live Local, and you will find awesome precession, cutting edge technology (beyond DHTML, XML and JavaScript) well managed data. Being software developer, these always attract me and I want to understand the scene behind those best software architectures/implementations. Over the last few days I was studying (hacking) Google maps and wanted to see how it works? Here are my investigations.
Tiles: The very first observation is – not whole map is fetched at once. Instead the entire map is divided into tiles and a series of Ajax requests are fired to retrieve some part of the actually map. As soon as a tile is fetched it is displayed at its position. Their position is well calculated no matter user drags the maps while requests are on the way. The benefit here is, the user interface remains responsive and it makes user eager to analyze an area of map as soon as it’s available.

Hi,
I’m {PREF=”ID=cfd6bd57439bc4a9:TM=1205732323:LM=1205732323:S=tT1f1NaLxjumQJbv”}. I’m a regular Internet surfer. On an average I’m online for more than 8 hours a day and that makes me to think of a new phrase - ‘my online presence’, and somewhere it may hurt my privacy.
In Web 2.0 big companies are competing to gain as much as information about Internet users that they can show targeted contents especially ads.
The game players have already begun their game. They know about what web pages I visit, they know my friends, they know what I prefer to buy online, then know which newspaper I read frequently, which mail account I use frequently, what do I search every day, what videos I watch online, where do I live, how much time I spend on Internet, what types of ads made me to click. They have my all photographs, my daily calendar/schedule, my mails (may be your credit card statements in form of emails), and all my chat conversations. They even know what music I listen, my attitude, my behavior, and even what I’m doing currently.
They say it’s all automatic, machines (computers) read and process information giving you personalized service and there is no human interference. But reality may be different. Is all that these sufficient to protect your privacy?
Here is a bigger fear, giving all of your information in the hands on one single body! A single mistake in handling such massive information can lead to world’s biggest controversy in user’s privacy.
In short, I don’t want anybody to know the fact that the wristwatch I have given to my girl-friend for her last birthday was of just 100 bucks!

These days I’m keeping a *big* eye on any new service they launched (any Internet service) and to be the first to use. Yesterday they launched code search, and I tried counter part of it:

I was waiting for Ahmadabad to be mapped on Google Earth!
And finally when I started Google Earth today found a new detailed layer for Ahmedadabad(Ahmadabad). Moreover various cities from Gujarat like Mehsana, Vadodra, Surat, Div-Daman, Veraval Patan and sea coast area are also mapped with high resolution satellite images. The newly developed city of Ahmedabad (off side the river) is not mapped entirely. Here are some snaps of Ahmedabad:

I remembered I have posted a comment on Vinod’s Blog about how much time they will take to fly from Kalol to Mumbai, and now the time has arrived.
Really, I am amazed and pleased to see ariel view of my house from Google Earth and flying to various parts of city.
{For security reasons, I’ve now uploaded ariel view of my house

If you still don’t have Google Earth, get it NOW!

Again……. they are not satisfied with Google Maps, Google Local, …. and came up with some thing new Google Transit
One of the best things about working at Google is a policy known as "20 percent time," which you can read about on our jobs page or in this post. Having the freedom to pursue projects during 20 percent of our work week means engineers can pursue a breadth of unique and interesting ideas without having to wait for anyone else.
Souce: Google Blogs
They have experimented on locale travel policies and launched a tool by which commuters can easily access schedule of public tranasport and plan their short trips and save money and time as they provide you cost of driving. Currently they only offer transit planning for the city of Portland.
And ofcourse we indians have to wait for these great services from Google.

Hey, I found something new on Google.
When I searched for "news movies" it grouped all results. Try this "resident evils". Can any one suggest what’s this? Has Google engine started working on content grouping technique?

Hey Everybody,
The most awaited service from Google is now live, Google base, on 15 Nov. They say :
Got something you want the world to see? Google Base is Google’s database into which you can easily submit all types of content. We’ll host your content and make it searchable online.
Use your GMail account to login. Really Google is being central data-holder for World’s information with GoogleSearch, GoogleMail, GoogleGroups, GoogleTalk (GTalk) and now GoogleBase. I use CCW - "Communication Centre of World" for Google. Let’s see how GBase can be usefull to us. Do u want something, just search on Google base.
Now the situation is the world can’t live without the word ‘Google’.
Just "goog" it……
