Database Design For Google App Engine - Tutorial

Are you looking for app engine database designing tutorials in the Internet? Well unfortunately there is very few information about it out there. Most of them are generic in nature, praising the stale common features of cloud computing we've heard over and over again - scalability, fast, non-relational stuffs in general etc. I kept searching for hours to find that most of the results were not useful to make a real world applications in GAE, and finally stumbled on some very valuable sources and techniques from several sources and gathered a final concepts you need to know to model data in Google app engine. I'll share it very comprehensively in this tutorial so that you don't need to gather it from different places as I did.

I'm quite experienced in relational database ( Oracle and MySQL) previously. I've been trying to design a product in Google App Engine since they provide free Java hosting. It was then that I got stuck wondering how to design my tables and schem…

Poovar Island In Kerala - Backwater Cruise Review

Even being a native of Thiruvananthapuram, I haven't went to many of the tourist attractions in here. Lately, I've decided to look up at least some of the most popular places and it was by chance that I got an opportunity to visit Poovar Isaland. It was nearly a 50 km ride from my place but we enjoyed all the way till there.


Once we reached there, it was nirvana! We were on a beach with sea on one side, where we could see the beautiful sunset, and backwaters a little forward on the the other side. The borders of backwaters followed a random curved path and were surrounded by lush green trees and bushes. The sinking sun's dark-orange rays passed through the clouds and hit the tides and moist land in front of it and made us feel that we were staring at some gold island. Later, the tourist guide Mr. Michel explained to us that this beach is also referred as the Golden Sand beach because of this magnificent effect of the sun.
The crowd of crows were unusually larger than other…

Asus Zenbook becomes the World's new Thinnest Ultrabook

Asus Zenbook is regarded as the one of the most marvelous engineering feat when today's class of Ultrabooks are concerned. All of it's details are designed with beauty in mind and a beast like performance behind. It has overthrown the current position of Acer S5 and became the  'World's new thinnest Ultrabook'. Not only Asus Zenbook, but there is a range of Ultrabooks from manufacturers like Sony, Dell and HP coming up with similar and smaller ultrabooks.

The Asus Zenbook comes loaded with elegant features that suit the actual human needs of the perfect technology and style blend. It has a 2-sec boot time and SSD harddisk that makes it stand out. One thing I found was, you could get the same configurations of  an Apple Macbook Air in the Asus Zenbook line for upto $200 cheaper price. If you pay the price of an Macbook Air for Zenbook you'd get a machine with a lot more features extra.

With great features and simplicity blend hopes are high that the Ultrabooks w…

Ubuntu Wireless Internet Not Working in Dell Mini

Wireless Internet have always been troublesome for me from the day I installed the Ubuntu 10.04 first in my Ubuntu. Those days the problem was that Ubuntu 10.04 didn't have the wireless drivers for Dell Mini ( Realtek/Broadcom). But then after a while when the Ubuntu 12.04 was out I upgraded to it and wireless drivers started working. Then later one day, for once, I turned off the wireless connection with the F2 key to connect using my LAN cable. The next thing I know is, I cant roam around with my dell mini because the wireless internet could not be enabled again. I got stuck with the whole LAN connection thing.

The Ubuntu 12.04 doesn't support turning back on the wireless internet once its turned off for dell mini.

 I lived with it for a few months and lately I searched all over the internet to see if anybody have fixed the issue. Fortunately, I found several solutions scattered out in the internet forums and guess what, one of them works!

The forum link with the solution for…

JavaScript Ads Injected by Asianet Dataline (ISP) Kerala

Asianet Dataline one of the leading Internet Service Providers in Kerala’s is now injecting JavaScript pop-up advertisements to the customer browsers.I directly inquired with their customer service and they've acknowledged the issue. JavaScript ad injection has been happening within all the customers subscribed for the unlimited data plans. I told them that this is a severe privacy breach as ads are being shown even when I’m logged into sites including financial transactions. True, the ads won’t be shown when the connection with another site is HTTPS, but that happens with most of the sites only when you click the ‘Make Payment’ button of most of the site, still the normal logged in session is vulnerable. This un-ethical approach cannot be identified by a normal user as there is no acknowledgement shown from Asianet that ads are shown by them. A normal customer thinks that he's just bugged by some site he visited. Eventually, they offered me (anyone who identify thi…

Best Bluetooth Keyboard for Blackberry Playbook | Logitech Tablet Keyboard for Andorid 3.0+

I’ve been using the Blackberry Playbook for quite few months now and I should say its an remarkably versatile device for anyone who love multitasking. Getting an external bluetooth keyboard for the Blackberry Playbook just enabled me use it like an amazing laptop with touchscreen. Fortunately, the (pseudo) brand market competition forced Blackberry to bring down the price for Blackberry up to 30% less than its initial price. Now, we’ve got a tablet with HD screen, 7 hours battery backup and an App Store with plenty of HD Games and Apps for cheap price, all with the Blackberry Playbook that cost around $200 now.

I did plenty of research about the best keyboards for Blackberry Playbook, most of the keyboard reviews where out-dated. The initial OS of Playbook didn’t support a lot of bluetooth keyboards but from OS 2.0 updates ( which is a mandatory update for all the Playbooks) things changed and a lot more devices were supported. There weren't much reviews about the new…

Hunting The Best Programmers in Kerala

Today India is so much focused on IT that almost 80% of the graduates are absorbed right away into IT companies soon after they pass-out. The fun part is, it doesn't even matter what stream they graduated in, but they are working in 'IT'. As a matter of fact, it's horrendous to interpolate about the other core industrial R&D future of India. I really hope the situation change and people start realizing the potential in doing what they love.

This scenario led me to explore weather real-passionate programmers exist in Kerala ( myself positioned being just a curious novice coder ). Students who set a part of their life for FOSS, those who love playing with API's found around the Internet, those who code for the fun of it and not for the hefty CTC wating at the MNCs. The search didn't disappoint me.

The 'Code Jam 2011' coding contest conducted by mobme.in in Kerala last year (2011) brought some very dedicated programmers to the public. If you are stude…

Graduation Day - A Reunion of Lifetime Friends

Finally after four years of study and toil, we got our degree certificates few days back.  And now we are all computer engineers ! Although it wasn't such an totally pleasant environment in our college there were several other things that changed us and made us what we are today. Of them,  one thing regarding me was the exciting journey through the world of computer science. Choosing my subject of passion have made me enjoy learning every bit of it. Another thing was that I was fortunate enough to meet some of the best friends I have in this world. They have amazed me in every way of their living and brought out the better human being in me. We forged a lot of life-time relationships on the go, now we know we are not gonna part any time soon.I feel I've learned a lot and gained a lot from there more than I would have from anywhere else.  Of course, Tirunelveli is a hot place, but you've got lot of good places to live and stay at Tirunelveli.

Kudos to each of the nice people…

Developing Facebook Applications In PhpFog

I've experimented developing facebook applications in several newly emerged venues, namely,
Goolge App Engine ( Java )Heroku ( Php ) I got the chance to explore these cloud platforms very deep and learned a lot on the way. For some reason or the other, none of them met my requirements ( they were quite vast :P ) . Now, I've got an account into phpfog.com and done with quite a few testing. So far, I feel it's the best cloud platform ( PaaS ) for facebook applications in php.

Good Sides of PhpFog

I felt the Git usage from linux is easier in phpfog.com than heroku
Allows all Image manipulation functions ( i.e. supports GD library )

It's quite easy to get started with a new facebook application in phpfog.

1. Sign-up at phpfog
2. Create a cloud
3. Create an application  --> Choose Facebook application from the list of presented applications
4. Download it with the Git

That was just an overview, detailed steps are described in their documentation very neatly.
