If you recall from about 15 years ago, cell phones and car phones all had large antennas that you typically pulled out before making a phone call. Here is one such phone picture.

Nowadays, cellphones and car phones dont seems to have such long antennas So where did these antennas go? Did we get technology that makes a phone work without an antenna? Thats not possible just yet.
What happened was that the fractal antennas were invented. The key feature of an antenna is its shape and the strength and quality of the signal received is a function of the length of the antenna. So the larger the antenna, the better the reception. How fractal antennas solve the problem is that they are made up of a shape that repeats it self (a fractal). Hence for a given length, a fractal antenna because of its folded self similar design occupies a very small amount of area. In fact, the shape of these antennas are commonly called “space filling curves”. Hence we are able to get a very long antenna in the smallest amount of space possible. This is the reason we dont need long external antennas. The antenna is built into the body of the phone.

Fractal antennas also have one other significant advantage. In various countries, cell phones operate in different bands of the radio spectrum. Cell phone manufacturers were faced with the need to build multiple antennas in order to make their phones work in these countries. However by taking a shape that can receive multiple bands and then replicating that into a fractal antenna, they are now able to make compact multi-band phone without significant increase in space.

Search and Advertising are the two most important product segments at Google. Search is the basis of the company and the reason for most users to come to Google. Advertising is the means through which those users are monetized. Though they were not the first, Google successfully developed and implemented text advertising in such a way that it was easily accessible to small advertisers. AdWords, the advertising system they developed is simple and hence consequently very powerful. Based on an auction model, you can bid as low as 5 cents for a keyword and run a simple text ad that will be displayed when a user searches for something similar to your keyword.
This enabled advertisers of all sizes to enter the advertising market where before they had a large barrier to entry. Most small companies do not have the large budgets needed to hire ad agencies and creative studios to develop advertising. Yet with adwords you can now run a successful campaign with just a couple of people. Text ads also provide a more efficient mechanism for advertising since the advertisers are matched very closely to the consumers, using the keywords the consumer typed. And finally, adwords provides the advertisers with a fine level of control and access to analytics to give them a never before seen level of understanding of how their consumers are interacting with their advertising.
So here is the secret in a nutshell: Allow a large number of advertisers (of all sizes) access to a large number of consumers, make the ads highly relevant and give the advertisers full control.
Using this strategy Google has come to dominate the text ad market and is bringing this same level of access, relevance and control to the online display ad market (with the acquisition of doubleclick) as well as the print, radio and TV markets. Hence I predict that Google will, within the next 5 years, dominate all forms of advertising and I look forward to oncoming advertising revolution!

Recently I got to see a google android phone. I am sorry to say that I was un-impressed. Given Google’s well known penchant for simplicity and usability in design, I expected a phone that at the very least was usable. My first opinion was “its clunky as a brick!”. This couldnt have been designed by google. Since google only made the platform, my guess was that the design shop employed by the phone manufacturer, HTC, didnt really do a good job. My friend, who owned the phone and works closely with telcos told me that google had extensive design oversight since this was the launch vehicle for the platform.
When I then heard about needing a google account to do most things on the phone, I was even more surprised. Isnt this supposed to be an open platform for folks to write applications and such… if so we should be able to use any authentication mechanism.
From a usability perspective, I had some irritants.. the screen not changing orientation as I turn the phone…this is one of the most common ways in which I read stuff on the iphone when there is lots of text. The icons werent as bright and clear as the iphone.
However, one place where this phone beats the iphone is that it does work as a phone. Compared to the dropped calls and other horror stories reported by most folks and on this blog, nobody seems to have problems making phone calls on this phone!!
So I would say this phone is a good start and hopefully the next revs will focus a lot more on design.. at the same time I hope there is tremendous acceptance of the platform for applications. Maybe this will be phone that will want me to switch from my ages old clam shell phone and enter the new world of 3G touch screen, gps enabled phones.

I recently began to notice a new (in my noob opinion) phenom. I thought most people had “a” blog where they spilled their guts out on all their thoughts, ideas, happening and hopes. Not so!! Given that people have many different facets to their personality, I found that their were creating a blog for each facet. So you have a cooking blog where folks write about the recipes they made and the restaurants they went to, a travel blog where their travels are recounted in detail with picture, a professional blog where they project a persona that will help them in job searches, and so on. I wonder what the average number of blogs per person is? this will probably indicate how many different facets there are to most people’s personalities.
I dont know how they get time to write for all these blogs, but they do. My second thought was “Why arent they doing this on Facebook?”: but it seems like the blog format and organization has a significant appeal. I think Facebook is missing an opportunity here for helping folks collect their thoughts and organize them on their facebook profile. Facebook:are you listening?
Well I gotta get crankin on those 3 other blogs… look for additions on the blogroll!!

Recently I read an article on the Economist that detailed the growth rate of mobile usage in the developing world including China and India. Of particular interest was the observation that many people in these countries will only access the Internet via mobile phones. That led me to thinking about a world where more people are accessing the internet via these small screen devices. Will the Web be the same? How will the pages change? Here are some possibilities:
- No large images on the pages that will not easily fit within the small screen. The small screen size will be used as the standard to create the thumbnail of images.
- Pages will be organized top to bottom rather than wide (this is already happening as a matter of style)
- Pages will be much shorter and will be more organized into mobile screen sized nuggets.
- Less typing and more point-and-click interfaces in the applications since typing will never be that easy on a small device (though I have seen many fast thumb typers!)
- More text to audio or embedded audio versions of pages for people to automatically listen to pages rather than read them
- Use of text messages for purchase confirmation, identity verification

In a previous post about the iphone, I questioned the reasoning behind buying a device that did not serve its primary purpose of enabling communication. It appears now that I am vindicated since my co-worker, much to his chagrin, had to confess that his iphone has crashed and rebooted numerous times due to the instability of the applications. Even BusinessWeek recently reported that the iphone was “more fun than phone” with lots of people reporting problems from activation to application failure to most popular complaint of dropped calls. In that story, one user who was expecting a baby started carrying two phones so that he wouldnt miss the all important call to rush to the hospital.
To me this is all a little ironical since I am actually a fan of Apple products. I used their powerbook for years and have never found another laptop as good (I am pushing my current employers to buy me a mac as well). But I think while the Iphone is a great product, its not a great phone and call me simple, but you wont see me buying one until it actually works well as a phone.

I recently joined a google experiment to try out different views on search results. Since I did a little bit of work on UI’s and presentation of search results, I was quite interested to see what google would come up with in place of the usual top 10 search results. Little did I know that google would unveil technology that would predict the future !!!

Here is a results page for the query “tim durham” and google is returning results all the way from 2010 through 2060! Now let me try and see if google can predict the next president! It does provide me with results all the way from 1850 to 2160…way too prescient for me!!
All the kidding aside, the technology was actually quite smart. Contrary to what I initially expected, that google was picking up any 4 digit number and thinking it was a date, most of these search results did have dates that were in the future. However, there is a big difference between the mention of a date and the date associated with the document. Getting the date in context is a much harder problem I think, but one I guess google hopes to solve.

In the opinion of my cube mate at work, I live in 2003 since I have an ancient clamshell Sony Ericsson Z500a that doesnt have most of the “necessary” features like email, big screen web-browsing or bluetooth. Its true that I havent upgraded my phone but the reason isnt that I am cheap or a technological philistine. Like most of my other devices, I like my phone for the job it does. I dont really care about frills or other “nice to have” features. The main need that my phone fulfills is the ability to keep in touch where ever I am. I am on a At&T/Cingular plan that has pretty good coverage in the bay area and this phone is rarely outta bars pretty much anywhere that I have been. The sound quality is also very good. Hence, the basis purpose of the phone is well served and I didnt see a need to change.
My officemate, who owns an iphone, on the other hand believes that his phone has completely changed his life and when he bought it, he didnt know he needed a big screen browser, or maps or email. But now that he has them, he cannot live without them. He gave me an example of where he and his friends changed their mind about a restaurant and he was able to look up a place to go to, get a map and call in a reservation seamlessly in so far that he no longer bothers to plan these outings ahead of time. He is also able to use the time on the train to catchup on all his news and feeds because the large screen of the iphone actually makes this feasible. He finds himself better connected as he can get his emails, post to his blog and twitter all from this device that he feels disconnected when he is without his iphone. Not to mention the other things such as decent camera and an 8GB ipod thats built in.
So enough of the iphone infomercial, I had a couple of questions (and for those folks who know me, they know that I’ll always have questions). First, with my utilitarian pov, I asked him “How does this phone work as a phone?”. He sheepishly answered that it really wasnt that good a phone as the voice quality wasnt great. My next was “I didnt seem to use any of these other things like an ipod, or a data plan, why would I need those now?”. Again he pointed out his radically changed life and said I would join the new connected generation that communicates on multiple streams very effeciently if I chose an iphone.
Hmm.. am not convinced, but a new issue is changing the game a bit.. the new California law that all cell phone usage in automobiles needs to be handsfree as of tomorrow (July 1st 2008). The Z500a doesnt have bluetooth and hence can only support wired handsfree solutions. So perhaps its time for me to upgrade anyway.. also my phone has started randomly rebooting every now and then.. wonder if AT&T is doing software updates or my phone is finally dying!
Anyways after all this chat, let me state the connundrum that I am facing explicitly: Am I really missing out in this tech savvy world if I dont have all these additional features in my phone? Is this really a generational change? and finally Should I go out an buy a new iphone?

Hi folks, this is a test of this new easy blogging service called Jott. As you all know I have always had a problem trying to get myself to type blog entries and I was complaining about this to a friend and he said well if you can speak into your phone, you can blog too. So he introduced me to this service called Jott. So the way Jott works is you set up an account and you connect a blog or multitude of other services and then listen
