Using Barcode Scanner for buying books in India

Posted by Thejesh GN On April - 13 - 20112 COMMENTS is the easiest way to get book prices from all e-stores in India. Given an ISBN code it gives prices from almost all e-stores in India, Very useful. But if you want to check book prices on the go (specially in a physical book store), then it’s not an easy. It’s tedious to get ISBN from the book and then enter it on mobile. What if we combine everything into simple android app I thought. has JSON API anyway. But wait yet another android app? How many apps will I install?

I have Barcode Scanner installed already. It can read barcodes off the book and pass that to any url. There you go. All I need to do was attach the read ISBN code to URL.


//custom search url

1. Once you install the barcode scanner
2. Go to settings
3. Scroll down to custom search url and add

4. Come back and scan the code from any book
5. Once it reads the code, click on custom search button
6. Voila!

Thanks to Swaroop for and cost on kindle would be great :)

Javascript API for wordpress posts

Posted by Thejesh GN On April - 11 - 20111 COMMENT

I have been looking at ways of using my activity stream. The stream is a WordPress blog and has various kinds of data (status msg, pictures, links and posts). Eventhough wordpress provides certain xml based APIs, I wanted something simple, that works on client side.

One of the requirement was to pull the latest mobile picture post, to display on my main blog. By default wordpress provides RSS feed for each author, category and tag. It wasnt that difficult to get the latest post but it is difficult to use XML in JavaScript. JSON seemed more useful than RSS. In the mean time Dave Winer was also thinking on similar lines. I thought about writing a plugin to convert RSS feed into JSON feed. But then whole wordpress family seems to like Dave (Remember supports RSS cloud). So I searched wordpress plugins. I found the one which I wanted – Feed JSON . Read the rest of this entry »

Wines of Bangalore

Posted by Thejesh GN On April - 3 - 20111 COMMENT

This blog post is not for under 18 (under 21 in some parts of the world). If you are not legally allowed to consume alcohol them dont read further :). Okay, for the record I like beer but then once in a while I like other alcohol too. Wine tastes good and also now that we have quite a few good local brands, its become affordable. So kind of become my second choice. Here are my favorite wines from Bangalore.

1. Grover Wines was established on 40 acres of land at the foot of the Nandi Hills in 1998. Today they have about 200+ acres. They produce La Réserve and Art collection series of wines.

La Réserve has a powerful bouquet of luscious ripe red and black fruits with an exquisite hint of spice. It combines grace and splendour on the palate with chocolate, coffee beans and vanilla flavours. The finish is long, ample and almost magical.

Art series will generally have a painting as label. At the bottom of the label you can actually find the artists name.

This relation between fine art and fine wine is wonderfully manifested in the Grover Vineyards “Art Collection”, with wine showing natural elegance and delicacy. Art Collection wines capture your imaginations with its breathtaking abundance of flavours, an extraordinary contrast of richness, freshness and finesse.
Looking at our wines’ labels is a feast for more than just the eyes.

La Réserve is around Rs. 700 and Art series start at around 550. I like Art series.

2. Big Banyan Wines are made through Big Banyan Vineyards at Ramnagaram. They have about 8 types of wines all with the alcohol content of 13%. Most of them are priced around Rs. 450 to Rs. 650.

3. Kinvah is produced by Nandi Valley Winer, Bangalore. They cater to both connoisseurs and novices. ‘Kinvah’ – name is derived from an ancient wine of the same name prevalent in the Mauryan era. I haven’t tasted it yet. I haven’t found one in shop yet. But you can buy them online and they deliver with in Bangalore only ( and free). Probably I will end up buying online. Price ranges around Rs.450.

Let me know if you know any other wine brands which are from Bangalore ( or near by). I would like to taste and also will add it to the list.

PS: Interesting how Bangalore has become center of wine culture in South India,

Kindle and hacking heroes

Posted by Thejesh GN On March - 14 - 20113 COMMENTS

amazon link to book After a very long break I am back into reading books. I must say my attention span has reduced. I had to concentrate hard for the first twenty pages to get into the groove. No internet (actually avoiding it) helped. I was at Hyderabad airport and flight was delayed by an hour. I generally plan well and hence I was there an hour before. I started reading Hackers – Heroes of computer revolution. Its an interesting book which gives history of computer hackers and how the culture grew. I cant believe I hadn’t read it until now. The definition of hacker I found in this book is one of the best

Hackers believe that essential lessons can be learned about the systems—about the world—from taking things apart, seeing how they work, and using this knowledge to create new and even more interesting things. They resent any person, physical barrier, or law that tries to keep them from doing this. This is especially true when a hacker wants to fix something that (from his point of view) is broken or needs improvement.

I couldnt resist, I switched on the tethering on my Nexus 1, connected my kindle to internet through wifi and shared this quote with my twitter followers. All this from with in Kindle and with out getting distracted. I am not sure if this is called social reading(?). First two chapters are available on Project Gutenberg for free download and whole book costs $11 on Kindle store. Its a must read book for anybody who want to know about hackers.
Some pictures I clicked. This is unpacking
Kindle unpacking
Clicked inside the flight
Kindle compared to coke bottle
May be this year I will read more books. Probably because I carry the whole library all the time. Kindle is the best thing I have bought in recent times.
BTW this wired article hackers will be the heroes of the next revolution by the same author Steven Levy is an interesing read.
