(Disclaimer: This is dedicated to some Technology stuff I read and found interesting over the past two weeks..)

A couple of weeks back, I saw this blog post called “The evolution of search in six minutes”, with a video attached. To me, it is a very well-made, down to earth post on, well, the evolution of search as we use it now…and how it might be in the future. I feel its a must watch for everyone irrespective of their search-technology awareness.

And yes, although I cannot understand a bit about “Quantum Computing”, this article on “Machine Learning with quantum algorithms”, on google research blog, made an interesting read. May be, at some point of time, if I can manage to understand the science behind it, I might try to put it forth in a more common-manish way . Thanks to Praneeth for sharing this.

For a couple of days in the past fortnight, I was addicted to the idea of “Forensic Linguistics”. I was searching for some Applications of linguistics (rather…Applied Linguistics) and this video, although not “extraordinarily” shot, made me more curious about the subject. I even managed to get a book introducing the concepts of Forensic Linguistics (online)…but, its so easy to drift when you don’t know so many things

Although I was fascinated by “Wolfram Alpha” when it was first announced, I soon drifted…well…I just told you why. But again, this particular blog post on Wolfram Alpha site, on handling/solving permutations related queries, fascinated me a lot

And then, I work in applying Language Technologies for Language Learning. I found something similar, but not related to “Language”, on the Communications of the ACM pages today. It is titled “Massive scale data mining for Education”. It talks about the use of massive math-query logs of students to predict clusters of difficult math problems, ways to track the progress of students etc. Yes, like they say, if it works, it will really be a massive scale student modeling. I loved the way the article ended. “We experiment, try different students on different problems, discover which exercises cause similar difficulties, and which help students break out of those difficulties. We learn paths in the data and models of the students. We learn to teach.” – It’d be interesting to see how it goes!

Back to CACM again, this piece on the duality of defining computing as an “instrument for human mind” (of a human mind and by a human mind too?? )… and connecting it to Steve Jobs and Dennis Ritchie ….was interesting too.

Lastly, again on CACM, there was this extremely insightful and well-written article on “Natural” Search User Interfaces by Marti Hearst. I just loved reading it and would recommend it to everyone interested in “Search”. Its a bit long…but surely worth it, IMHO.

Jai Hind, for now!!

Hi here is the video series of sharepoint 2010. The first is about installing sharepoint 2010 on windows 7 and more videos to come soon

Sometimes in windows 7 start menu search will not work. Many blogs will tell you to edit the registry. But it is not recommended. Microsoft released the hotfix for this. Download at: http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=977380&kbln=en-us

First things first. What is Solr?

“Solr is the popular, blazing fast open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world’s largest internet sites. “
-Says the Apache Solr website. I can’t explain it better than this, anyways.

I first used Solr in Jan 2010 and have been using it at various stages of my professional as well as student life, ever since. To say the least, its amazing! I was just browsing through this book – “Solr 1.4 Enterprise Search Server” (by David Smiley and Eric Pugh) today. Oh, well, I should have read it in 2010 ideally. But, I found it now. There was one more which I found a couple of weeks ago, “Apache Solr 3.1 Cookbook” by Rafal Kuc. I thought it would be good to put the set of related links that I found useful over a period of time, so that others like me, who want to begin with Solr, might find them useful too. There might be N such posts on the web. But, this is partly for my own log too!

1) I remember starting at this presentation on “What is Solr?” by Tom Hill (courtesy: my google bookmarks). It might be a bit dated now, though.

2) This article by Grant Ingersoll, at IBM Developer works, was another useful one, back then.

3) Solr Wiki is the best source for everything, ofcourse. (http://wiki.apache.org/solr)

4) “Seven Deadly Sins of Solr” on LucidImagination pages, was another one, which helped me a lot during the initial days. In general, LucidImagination has some really good articles on Solr, for users of all stages of Solr experience.

5) In my view, setting Solr in Eclipse, with Tomcat is a real irritating issue. Well, it’s no difficult. Its straight forward. But, I don’t (perhaps won’t) understand Tomcat behavior in Eclipse, personally. This blogpost gives an overview of what to do to make a test Solr server work in your eclipse.

6) I was wondering about the crawling part of Solr. I always used external crawlers (Heritrix, Wget and even 80legs etc) to get required data. But there seem to be decent amount of options, which I did not try out, yet. Some of them -
a) Using Nutch with Solr – a LucidImagination article (I did play around with Nutch a while ago, but I did not know about Solr back then!)
b) Youseer, which uses Heritrix to crawl and Solr to index.
c) Crawl-Anywhere, another thing that I read about recently, which uses their own crawler, with Solr Indexer.

7) Here is a good example of reading Solr results, from SolrJ, a java library for Solr. I particularly cite this because, I had a tough time in finding an example on using SolrJ to read Solr results . Mats Lindh’s post was also a very useful one to use Solrj.

The best part of this is, I need not read Solr results in java alone. I can develop my webapp in any language I want and Solr supports it! (Well, I know that people use Java, Ruby and Python. Since Solr supports JSON, I guess it can be used in other languages too, perhaps).

8 ) The best place to go, for any query about Solr is the Solr users group and its archives Its a very friendly group, where you can always be assured that you will get a response.

9) I tried using the Solr-UIMA integration, but it did not work my UIMA annotators. So, I left it there and managed to do the UIMA stuff before sending the doc to Solr . It might look like “running away from the problem”, but it works.

10) Time and again, I am amazed at the new stuff I discover about Solr. The books I mentioned above, are really good sources of information. You can perhaps manage to find pirated pdfs online. I don’t want to give links myself, here.

11) Oh, I did mention links on setting up Solr to work, Knowing more about Solr and Accessing the search results of Solr using SolrJ. But, I did not mention about indexing a set of documents. I started with an example code by Grant Ingersoll. I can’t place that right now, but found this Solr-user group mail, which can serve as an example. Here is one more from Lucid Imagination, which uses TIKA parser.

Happy Solr-ing.
(Hoping that someday, someone like me, will find this post useful! Perhaps, this is an attempt to give back to the community! )

Hi Sridhar – Thanks for the video. I agree with you on expecting the major responsibility lying wiht Financial organizations who set up these ATMs since customers on remote areas are not completely aware of these technical traps. Perhaps, insurance coverage at free of cost from Banks may be optimal, similar to FDIC in US. More user awareness sessions to be conducted or communicated thru post by banks atleast once a year.

thank you sir
