<blockquote><h3>Sanskrit centre struggles to stay alive</h3>
<p>The <a href="http://www.ksrisanskrit.in/">Kuppuswami Sastri Research Institute</a> attached to the Sanskrit College in Mylapore is in doldrums because of lack of government patronage.
<p>The Institute, one of the three involved in Sanskrit research in the country, has been surviving on private donations. With not enough resources, the management is unable to pay the faculty the benefits of the sixth pay commission.
<p>Institute director V Kameswari said the Union government stopped its financial support in 1995, after which it has been solely dependent on donations. &#8220;The institute has a trove of rare palm leaf manuscripts and books not just about Sanskrit literature but also on architecture, fine arts, geography, history and astronomy in Sanskrit,&#8221; says Kameswari.
<p>The two other such institutes are the R G Bandarkar Sanskrit Institute in Pune and the Ganganath Jha Sanskrit Institute in Allahabad. &#8220;We have requested a onetime grant from the Union planning commission and also annual assistance from the Rashtriya Sanskrit Sansthan, but are yet to get any support,&#8221; says K S Balasubramanian, deputy director of the institute. The plan panel had given grants to the Mumbai Asiatic Society and Kolkata-based Asiatic Society.
<p>The institute was getting about 10 lakh till 1995 but due to a misunderstanding between the government-appointed members of the governing committee and the management, the aid was stopped. Today, there are 24 scholars at the institute, most of them women doing their PhDs. &#8220;Scholars from across the country and world visit the institute. We send out publications to many foreign universities and they in turn send their publications which are preserved here,&#8221; says Kameswari.
<p>The institute was started as a private non-profit organisation in 1944 in memory of Kuppuswami Sastri, a renowned Sanskrit scholar. It has a library with books on astronomy, architecture, fine arts, mathematics, Vedas, Puranas, Upanishads and various branches of science.
<p>&#8220;A private entrepreneur made a donation with which we have air-conditioned the library. The palm-leaf manuscripts in the library are 600 to 1,000 years old. Many of them are in Grantha script. We also have books on Jainism that speak about solving mathematical equations and explain geographical concepts,&#8221; says Kameswari, who is worried about keeping the ancient language alive.</p>

			<content:encoded><![CDATA[<p>Five years ago, I built a <a href="http://www.s-anand.net/hindi">song search engine</a> – mainly because I needed to listen to songs. Three years ago, I stopped updating it – mainly because I stopped listening to songs actively, and have been busy since. For those of you who have been using my site for music: my apologies.</p>
<p>These days, I don’t really find the need to download music. <a href="http://www.youtube.com/">YouTube</a> has most of the songs I need. Bandwidth is pretty good too <a href="https://twitter.com/#!/sanand0/status/166886668958318592">even when on the move</a>.</p>
<p>But when I do need to download music, this is my new workflow.</p>
<ol>
<li>Find the song on <a href="http://www.youtube.com/">YouTube</a>. (Misspellings are still an issue, but you’ll usually find what you need)
<li>Download the video. <a href="http://keepvid.com/">Keepvid</a> is the simple option. <a href="http://rg3.github.com/youtube-dl/">youtube-dl</a> is the geek’s option (for multiple downloads)
<li>Use <a href="http://www.videolan.org/vlc/">VLC</a> – the swiss-army knife of media – to convert the video into an MP3.</li>
</ol>
<p>That last step requires a bit of explaining. It’s very simple once you know how, but it took me a few months to get it right. So here goes.</p>
<p><strong>Select the Convert / Save option in the Media menu.</strong></p>
<p><a href="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-1.png"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top: 0px; border-right: 0px; padding-top: 0px" title="audio-conversion-1" border="0" alt="audio-conversion-1" src="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-1_thumb.png" width="550" height="477"></a></p>
<p><strong>Click on Add to open file you want to convert.</strong> You can pick a track from an disk as well if you want to rip an audio CD or a DVD.</p>
<p><a href="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-2.png"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top: 0px; border-right: 0px; padding-top: 0px" title="audio-conversion-2" border="0" alt="audio-conversion-2" src="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-2_thumb.png" width="550" height="556"></a></p>
<p><strong>Choose the file.</strong></p>
<p><a href="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-3.png"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top: 0px; border-right: 0px; padding-top: 0px" title="audio-conversion-3" border="0" alt="audio-conversion-3" src="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-3_thumb.png" width="550" height="382"></a></p>
<p><strong>Click on Convert / Save.</strong></p>
<p><a href="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-4.png"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top: 0px; border-right: 0px; padding-top: 0px" title="audio-conversion-4" border="0" alt="audio-conversion-4" src="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-4_thumb.png" width="550" height="556"></a></p>
<p><strong>Type the destination filename.</strong> Make sure you type the full file name, and not just the name of the folder.</p>
<p><a href="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-5.png"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top: 0px; border-right: 0px; padding-top: 0px" title="audio-conversion-5" border="0" alt="audio-conversion-5" src="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-5_thumb.png" width="564" height="425"></a></p>
<p><strong>Select the output format you want under Settings – Profile.</strong> You can tweak the bitrate with the settings button, but I usually don’t bother.</p>
<p><a href="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-6.png"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top: 0px; border-right: 0px; padding-top: 0px" title="audio-conversion-6" border="0" alt="audio-conversion-6" src="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-6_thumb.png" width="564" height="425"></a></p>
<p><strong>When you click on the Start button, the file will be converted</strong> or the CD will be ripped. You’ll see the position marker move fairly fast.</p>
<p><a href="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-7.png"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top: 0px; border-right: 0px; padding-top: 0px" title="audio-conversion-7" border="0" alt="audio-conversion-7" src="http://www.s-anand.net/blog/wp-content/uploads/audio-conversion-7_thumb.png" width="550" height="477"></a></p>
<p>&nbsp;</p>
<p>The only problem I have with this method is that I can’t seem to do batch conversions easily enough with the GUI. Does anyone have any other workflow they like?</p>

<p>I’m not sure what it is that leads to this kind of correlation. In fact, the full correlation between every pair of subjects (for 2011) is below:</p>

<p>What inferences would <em>you</em> draw from this?</p>
<p>And what do you think is the <em>reason</em> for this?</p>

			<content:encoded><![CDATA[<p>Reading, wRiting and aRithmetic are the 3 &#8216;R&#8217;s that are taught at school. I was thinking about their relevance today.</p>
<p>Reading continues to be relevant. The volume of information available today is more than before. So you need to read faster AND smarter. (If there was one good thing that came out of my IIM coaching classes, it was the ability to read fast, and making it subconscious.)</p>
<p>But I wouldn&#8217;t say the same of writing. In the last 10 years, I have typed several hundred more pages than I&#8217;ve written. So have all my friends.</p>
<p>Yesterday, I was at a bank with a relationship manager as he was taking notes in paper and pen. I do the same on occassion. I looked at his notes later. I could not understand a single word. &#8220;Don&#8217;t worry, sir, I can read it. I&#8217;ll type it out and mail you,&#8221; he said. And he did.</p>
<p>Writing seems to have become a device for personal memory, not communication. He&#8217;s faster at writing than typing, perhaps. Or note taking is more convenient on paper. But for communication, he still prefers a typed format. So do I, and most other people.</p>
<p>Perhaps writing will fade. Perhaps not. I don&#8217;t know. But what I do know is that typing has become more important than writing. Yet, writing is taught more at school than typing.</p>
<p>(A broader aspect of writing, though, is expressing oneself. That will remain important, of course.)</p>
<p>The third R is aRithmetic. When I was 12, I could multiply four-digit numbers in my head reasonably well. I could recite 50 digits of Pi. I could do long division. Today, I can&#8217;t. Nor can my friends. Nor have we needed to. A good feel for the numbers has helped, but not the actual mechanics of the calculations.</p>
<p>We had an undergraduate course in statistics that taught us how to solve a linear regression problem. That skill went completely unused. I&#8217;ve never since used regression without a computer. We had a graduate course in statistics that taught us how to INTERPRET the results of a linear regression. That was worth it&#8217;s weight in gold.</p>
<p>This is not a critique of the three Rs. Rather, an attempt to re-interpret them. It&#8217;s about comprehension, expression and computation. Two decades ago, it was reading, writing and arithmetic. Today, it&#8217;s reading, typing and computing.</p>
<p>Computers will grow more powerful. It may be worth planning for it. Teaching the ability to use them can go a long way. A tool like Excel for general purpose computing gives incredible power in the hands of people. It&#8217;s worth training children for that.</p>
<p>If I oversimplified, I&#8217;d say children must learn typing and Excel.</p>
<p>Over the next few years, this is something I plan to work on. Making sure schools and parents do this. Any suggestions or leads you may have are welcome!</p>
