I woke up touch early (4am) to watch the final day of the fourth India-England test match at Oval. First, I checked cricinfo and wow, Tendulkar was still batting. After a series of troubles and time outs, I managed to find one video streaming link. He wasn’t at the imperial best, but all looked set for that 100th 100. Other than that momentary hope, there was not even a glimpse of hope in the test match result. Anyway, much like the millions (or billions) all across the globe, I waited to see that 100. But alas! On 91, yet again a 90s misfortune for Tendulkar. Out LBW, somewhat contentious, but not overly outrageous a decision by an umpire anyway. He wasn’t at his imperial best in this series, but he was looking good for one to make that 100th number. Now, we will have to wait again for more from the great man.

Now the England white wash over India in a 4 test match series. The BCCI and the much hopeless cricket administration is putting the nails on the test cricket coffin. What a pity! For them IPL is the cash cow. Everything else is just for time pass. When a lot of money is poured in, even the most respected commentators and ex test cricket players have swallowed tongues. No one will put a blame on preparation. An IPL soon after world cup have paid more than damage to Indian cricket. Half fit players for an all important test series? In the end, made a mockery of test cricket!

I was long curious about the origin of the name San Diego. I feel ashamed of myself if I don’t know a bit of history of the place where I stay. As far as history is concerned, to a decent extend, I was indeed aware about the history of California, including San Diego. But, I didn’t know where the name San Diego originated from. Thanks to this and a bunch of Google/Wikipedia hits, here I know why San Diego!

Here is the official explanation behind the name San Diego, at least per San Diego Historical Society.  The Spanish explorer Sebastian Vizcanio arrived San Diego from the Mexican coast of Acapulco . This was in the year 1602 and it took. He had departed Acapulco with four ships on May 5, 1602 and only three of them, his flagship ship being San Diego, made it to what is now known as San Diego bay.  Besides the flagship ship named San Diego, he had two other ships arrived at the bay. They are the San Tomás and the Tres Reyes. The exact date (as per history) of his arrival in San Diego bay is November 10, 1602. Acapulco found no qualms in naming the new coastal area by his flagship ship name and hence we now live in the beautiful San Diego and not San Thomas or Tres Reyes, huh! Apparently, there was another reason why Acapulco chose San Diego. It was to honor the Mission Basilica San Diego de Alcalá.

Windowing techniques have always offered confusion to me. The hardest one was to remember what is what and how they looked in frequency domain (the time domain view was something thankfully I recollect from the names). I hit upon this yet again while trying to map the theoretical spectrum to spectrum computed from discrete samples (for an OFDM modulated signal) and then to analog spectrum measured by an instrument (By the way, I figured out that, the closest discrete technique which maps to the spectrum computation in spectrum analyzer is the Danielle method, which for some reason is not there in Matlab!) . For ages, I was using the pwelch (now spectrum.pwelch) function (pwelch method to estimate the spectrum) to compute/plot the spectrum in Matlab. Usually, some windowing as well is used to adjust the mean square versus resolution.  What window function is more suitable is something that I’ve never mastered. These days, doing a Wikipedia search to find a temporary fix and then move on is the adopted, yet not entirely satisfying strategy. The frequency domain characteristic of the popular window functions are now in here for reference, thanks to Marcel Müller. Since I may need it once in a while, I’ll keep a copy here for my own selfish quick reference. If you ever need to grab a copy, please be aware that, the ownership of this is with them.

Just came across a neat little Google App for Meegenius to use with Google chrome. Quite cute and nice. Basically, a little story telling/book reading (with audio) app for small kids; Essentially, this is an add on to the Meegenius online book store/reading for kids while using Google Chrome as the browser. I am sure kids will have an enjoyable ride with this. I found it to be incredibly cute!

Well, if you are not really obsessed with Google chrome, then you can as well go direct to MeeGenius and read it there!

One thing I like (besides it being an absolute gem of  a search genie) about Google is their customized logos, usually marking the day in history. Today, on Pierre de Fermat’s b’day they setup a nice and cute logo. On the logo, the famous Fermat’s last theorem is pictured.  I think, it was in 1993 I first, heard of this famous problem when England born Oxford/Princeton mathematician Andrew Wiles unveiled the solution. In 1996 or so, there was this documentary telecast in BBC on Andrew Wiles and his journey to solving one of the greatest (if not greatest, one of the most talked about problem) problem in the history of mathematics. A high class documentary is archived in youtube. I am not sure whether it was BBC who made it originally. I see that some youtube link shows UTV.

Here is another piece of writing/blog on this subject (by Chloe Albanesius).
