In this post, I'll introduce you to web resources that help you to catch up with the news in Sanskrit, free of cost, everyday.
1. All India Radio (AIR)
Since the 1980s, Indians are addicted to two things - the television and the radio, or more precisely, Doordarshan and Akashavani, as they were then called.If you think you are missing those good old times, here's some solace.The AIR has been broadcasting news in several languages everyday. You can subscribe to the RSS feed of Sanskrit news through this link:
http://sanskritdocuments.org/news/air_news.xml
I use Google Reader which neatly streams the MP3 right inside the browser. If youchoose to listen regularly, just register your name on this link. Of course, I am the 18-th on the list !You can find all previous archives and the news transcripts at Sanskrit Documents
2. Sudharma -- World's only Sanskrit Newspaper
Sudharma was started in 1970 by a Mysorean, Varadaraja Iyengar. As such, you'll find a lot of local news, in and around Bangalore.This newspaper is struggling for its existence. The least you can do is to spread awareness aboutthis to your friends. You can subscribe to its RSS feeds here:

26.01.10: Software :: One input, Multiple Outputs
There are various document formats in use today: Microsoft Word (*.doc), Open Office (*.odf), Portable Document Format (*.pdf), XML, HTML, Docbook, Rich Text Format (*.rtf), Unix man pages, GNU N/T/ROFF, GNU Info, GNU Texi, etc. However, the best document format that exists, according to me, is LaTeX. It has been in use for several decades and has stood the test of time. Nothing can beat LaTeX (or TeX, in general) when it comes to typesetting Mathematics. In this post, I'll give examples of a software converters which accept LaTeX input and convert it to various other output formats. I call this as the principle of "one input, multiple output" -- write once and use it in whatever format you want ! As an example, head over to my Channel Estimation article, which was automatically converted from LaTeX to XHTML.

In Signal Processing and Communications, one often has to deal with unknown signals. For example, the wireless channel (air medium) distorts the transmitted signal in so many ways (multipath fading, ISI, etc.) that the receiver has to use its own methods to recover the signal. Generally, such signals are modeled as stochastic random processes and statistical methods are used to "demystify" the received waveform. The air medium can be considered to be a time-varying FIR filter and the receiver unit must estimate the properties of this wireless medium.Such techniques are called Channel Estimation methods.
I have begun a series of articles, in which I'll explain the various methods of channel estimation. In this post, I'll explain a method called as Maximum Likelihood Estimate. I give an example on how to estimate the mean and variance of the wireless channel. To start with, I consider a time-invariant () system. Later, we'll consider time-varying systems. This article involves so much math that HTML can't cope with it. I used LaTeX and converted it to pdf. You can download it here.

19.01.10: Math :: Sloane's Integer Sequences ( in Kannada ! )
The Online Encyclopedia of Integer Sequences is a well-known place on the web. It is maintained by the famous mathematician Neil Sloane. Each sequence has a unique ID, for example A000796 gives the digits of pi. The format is Axxxxxx where the x's represent a six-digit number.
I had an excellent opportunity to interact with Sloane over email. We have one thing in common - love for math and languages. I volunteered to translate his homepage in Kannada. Click here for OEIS in Kannada. He has put up my name on his website, in the Acknowledments section. Scroll down to see my name ! Thanks Dr. Sloane !

03.01.10: Math :: Special Functions Download
A Special Function is a function which is quite different from elementary functions (like the trig functions). Often, it is named after a mathematician who first discovered its properties. For example, the Bessel functions and the Legendre polynomials. There are over a hundred special functions in mathematics. Most of them can be formulated as solutions to differential equations. I first got familiar with them while browsing the Mathematica book.
Nowadays, I use Python for most of my numerical computing. The excellent SciPy library (Scientific Python) includes a package on special functions: "from scipy.special import * ". Two years ago, I had written an introductory article about Special Functions. You can download it for free here: SpecialFunc.pdf [240 KB]. I wrote the article in LaTeX and used pdfTex for typesetting.
Feel free to comment on the article !

01.01.10: Happy New Year !
2010 is here ! And my website is up and running, better than ever. Nucleus made my job so easier than I thought. I edited the "skins" and "templates" ; that's it. Ready !
Yesterday, I missed to explain why my blog is called "Circuit Broken". The Internet is basically a network. In my language, it's a Circuit connecting various components. The components can be a websites, search engines, e-mail clients, blogs and what not. Whenever a part of the circuit breaks, we have an Open Circuit. I look upon my blog as a way to "open" up my mind in to the Circuit. There you have it !
