Top 10 power producing states in India

2012-05-09T01:34:00.000+05:30

India is the world’s 4th largest power producing country. The power production/generation capacity is otherwise known as installed capacity. This capacity is usually higher than the actual generation, since not all energy sources provide maximum output throughout the year.

Percentage share of power production sources in India

The major source of power in India continues to be derived from Thermal power, ie, from burning coal or oil, followed by hydro power. Renewable energy sources include Small Hydro Projects, Biomass Gasifiers, Biomass Power, Urban & Industrial Waste to Power sources and Wind power.

Top 10 power producing states in India

Maharashtra generates the highest amount of power among all the states of India.

Top 10 Nuclear power producing states in India

Maharashtra generates the highest amount of power in the nuclear segment too.

Top 10 Hydro power producing states in India

Andhra Pradesh generates the highest amount of hydro power among all the states of India.

Top 10 Renewable energy producing states in India

Tamilnadu produces the highest amount of renewable energy among all the states. Renewable energy includes wind power, solar power and biomass.

Solar power plants in Tamilnadu

2012-05-07T22:19:00.000+05:30

Tamilnadu has 3 solar power plants in operation. All three are based on PV (Photovoltaic cell) technology.
Two of them at Sivaganga district and one at Mayiladuthurai district. All these projects were supported by Govenment of India, under the Jawaharlal Nehru National Solar Mission (JNNSM) which aims to create an enabling policy framework for the deployment of 20,000 MW of solar power by 2022.

1MW Solar plant at Mayiladuthurai

The 1 megawatt plant was synchronised to the grid on June 10,2011.
The project uses 4,400 crystalline silicon modules of 230 Watts each spread out over an area of 5.5 acres. The solar power plant is owned by B&G Solar Private Limited, located at Komal West Village, Mayiladuthurai, in Tami Nadu.
It was installed and commissioned by Tata BP Solar India Ltd, a joint venture of Tata Power and BP Solar. The plant provides power to electricity grid of Tamilnadu Electricity Board. B&G Solar provides electricity under a Power Purchase Agreement (PPA) with the TNEB, by which TNEB will purchase power for 25 years.

1MW Solar plant at Sivaganga

The 1 megawatt plant was commissioned on July 25, 2011 and connected to TNEB grid.
The plant is commissioned by RL Clean Power Private Limited at Marakathoor village of Sivaganga district.

5 MW solar farm at Sivaganga in Tamil Nadu

The 5MW Solar power plant at Iynarkulam village of Sivaganga is the country's largest and first 5MW plant.
Thin film Photovoltaic cell technology was used in this solar power plant. The solar plant was commissioned by Moser Baer Clean Energy Limited (MBCEL).The plant was commissioned in early 2011, and connected to Tamilnadu Electricity Board's grid.

Five control rooms were set up to control the production and supply the same to the grid. As many as 61000 modules were established in different rows in such a way to absorb the sun radiation. Most of the 65 acre land has been occupied by modules and panels, which were produced by an indigenous technology.

According to the company sources, the solar farm was established at a cost of around Rs.100 crore.Funding for the installation came from the International Finance Corporation and the IDBI bank.

Google apps free edition

2012-03-29T23:38:00.000+05:30

Google recently switched Google Apps to a paid service.
But, their free service with 10 users is still available, but, not listed.

The reason is that Google has rechristened "Google Apps" to "Google Apps for Business".

Google Apps for non-business purposes are listed in the short link menu above the footer.
Users can sign up for Google Apps Free edition (Google Apps for Groups) through this link.

Here is a timeline (history of Google Apps) since its inception,

Feb 2006 - Google created "Gmail for your domain", that later became primary component of Google Apps
August 2006 - Google launched "Google Apps" integrating Email, Calendar, Talk and Pages.
Feb 2007- Google launched Premium Edition for Enterprise
July 2007- Google removed "beta" tag from all Google Apps products
May 2011- Google reduced free account limit from 50 to 10
End of 2011 - Google removed all references to free accounts and gives only a 30 day trail version of "Google Apps for Business"

History of Indian wireless networks

2012-03-18T01:55:00.000+05:30

By analyzing the user base of wireless (GSM/CDMA) networks in India, it is possible to trace the rise and fall of the network operators.

Below graph depicts the user base of wireless networks in India from 2005 to 2011.

Cellular network operators' user base in India

The numbers of smaller operators are trailing at the bottom of the graph, click on the graph to see a larger version of the graph image.
This is compiled from the data publicly available from the Cellular Operators Association of India.
(Disclaimer: Reliance decided not to submit their data to COAI from March 2010 onwards.Certain CDMA operators are also listed since COAI lists them. Certain month data are taken from average of nearby months since COAI ignored to supply the data for the same.)

Insights about GSM Cellular network operators:

- Airtel has always been the market leader among the wireless service providers in India
- BSNL had initial lead, but lost user base and started to lag behind Idea
- Hutch became Hutchisson Essar in 2006, Hutchisson Essar was acquired by Vodafone in 2007
- Idea went from No.4 to No.3 beating BSNL during the end of 2009

Rise of BSNL's user base

Despite being a public sector undertaking, BSNL showed consistent growth and now remains 4th largest network in India.

Rise and fall of BPL

BPL had a shaky history of user retention and finally became Loop Mobile in May 2009.

Sustainability of human resource consumption

2012-02-21T23:10:00.000+05:30

The resources that mankind uses is finite.The resources usually rejuvenate over a period of time. Using the resources at a higher rate than resource production/rejuvenation by nature causes resource overuse and depletion. Below graph summarizes the relationship between resource consumption and resource availability by different country groups as on 2010.

Resource Consumption vs Resource Availability across countries

The article interprets,
"Ecological Footprint of Consumption" as "Resource consumption"
"Total Biocapacity" as "Resource Availability".

Ecological Footprint explained:

Ecological Footprint, Courtesy: Global FootPrint Network

Turning resources into waste faster than waste can be turned back into resources puts us in global ecological overshoot, depleting the very resources on which human life and biodiversity depend.

Resource Availability and Resource Consumption through time

The result is collapsing fisheries, diminishing forest cover, depletion of fresh water systems, and the build up of carbon dioxide emissions, which creates problems like global climate change. These are just a few of the most noticeable effects of overshoot.

Overshoot also contributes to resource conflicts and wars, mass migrations, famine, disease and other human tragedies and tends to have a disproportionate impact on the poor, who cannot buy their way out of the problem by getting resources from somewhere else.

The first step in ending resource over-use is to recognize and acknowledge resource over-use.

Google allows multiple simultaneous login

2012-01-26T19:00:00.000+05:30

Google had recently introduces a very useful feature.
Most people had signed up separately for different Google services like Youtube, Orkut initially.
Ever since Google converted all accounts into Google accounts, simultaneously logging into those services became impossible and most users had to resort to using different browsers at the same time.
Youtube in Firefox, Gmail in IE etc became the norms to use multiple Google accounts simulaneously.
All these issues were solved, when Google introduced "Multiple Sign-in" feature.

When signed in into one account, the profile menu has the link to "Sign in into another account".

In above screenshot, both accounts are listed in the drop-down and the user can switch between the accounts seamlessly.

Find duplicate numbers in Nokia C6 address book

2011-11-08T22:30:00.000+05:30

Duplicate entries in mobile phone address book causes names not to be displayed and create unnecessary confusions.
Certain models of Samsung and Sony Ericsson phones avoid this by alerting whenever already exisitng number is saved into the address book.Unfortunately, most Nokia phones do not have this feature.
There arises a need to find duplicate entries in Nokia phone. This trick works only in Symbian phones since Symbian phones alone have the phone search feature.

To find duplicate contacts in Nokia phones, simply open the "Search" application and enter the number, the phone will display all names under which the number is saved.

Nokia Symbian c6 home screen with the "Search" shortcut

The "Search" application with the magnifying glass icon can be found within the "Application" folder within the main menu.

Nokia C6 Symbian V5 Search Application

Lets search for Batman...who's that "Bruce Wayne"?

Upon searching for the number within the "Search application", the phone numbers with the same number are displayed.

Visualising website keyword data

2011-11-04T01:53:00.000+05:30

Keyword data available in Google analytics can be visualized in many ways. The data must be first exported from Google Analytics in excel format.

Two such visualization platforms i tested are,
1. IBM Many Eyes
2. TagCrowd.com

IBM ManyEyes is a project by IBM.
There is a need to make a simple free signup at the ManyEyes project page in order to use it.
After signup, data needs to be copy/pasted from excel to the site.
I have copy/pasted the keyword data i extracted from Google Analytics and uploaded the data to IBM and created the following visualizations.

Word Tree Visualization of bharathtech.com's Keyword data in IBM Many Eyes project - Nokia keyword

Word Tree Visualization of bharathtech.com's Keyword data in IBM Many Eyes project - Play keyword

Tag Cloud Visualization of bharathtech.com's Keyword data in IBM Many Eyes project - sing;e keyword

Tag Cloud Visualization of bharathtech.com's Keyword data in IBM Many Eyes project - double keyword

Word Cloud Visualization of bharathtech.com's Keyword data in IBM Many Eyes project

IBM's Many Eyes project website.

TagCrowd.com is an independent website by Daniel Steinbock
Tag crowd requires no signup and can visualize text data alone.
Simply copy/paste the data and immediately the tag cloud appears as below.

Export as CSV for Excel bug in new Google Analytics

2011-10-30T00:48:00.000+05:30

Exporting data as "CSV for Excel" is providing data in improper format.
When opened in excel, the data shows up in single column like the below screenshot.

Notice how the data appears in a single column.
To fix this bug in Excel, select the column, then goto the Data tab.Then Click on the "Text to Columns" button as in screenshot.

Text to Columns feature in Excel for fixing the Google Analytics new version bug

Then follow the steps as in screenshots. Click Next on the first window.

Select comma as the delimiter and click Finish.
Select Ok in the confirmation box that opens.

The text will all be sorted out as in below screenshot.

Thats all.

For those who cannot follow all these steps, simply select "CSV" in the export option instead of "CSV for Excel". The CSV version does not club the columns in excel!

View and export more than 500 rows of data in Google Analytics

2011-10-30T00:22:00.001+05:30

Google Analytics provides a maximum of 500 rows of data per page. This applies to all data within Google Analytics, such as , keywords, referrers, content pages etc. Sometimes, the need comes to view and export more than 500 rows of data in a single page.

Google says that full data can be exported when we export as CSV.
But, sometimes, we need to see the maximum data in the web interface itself.

More than 500 rows can be fetched easily.Even Google officially recommends this for advanced users.
Remember that this trick no longer works in the older GA version. This will only work out in the newer GA version.
First,we need to get to the report page where we want more than 500 rows.Then change the row count from the default 10 to 500.

Screenshot of Google Analytics Keywords Page - Address bar parameter is highlighted in green

Notice the green highlighted area, it contains the parameter called explorer-table.rowCount%3D500

Change this 500 number to any number that is needed.Here, i am changing it into 600. You can change it into 6000, if your analytics profile has that much data.
Dont forget to press "Enter" after modifying this number.

Now, the page will display 600 rows, as in below screenshot.

Nokia Message icon flashing problem solved

2011-05-18T01:53:00.000+05:30

Recently, the Message alert icon on my C6-00 mobile started to blink, even when the inbox is empty.
This happened in my previous mobile N-73 when there is no space in phone memory to recieve new messages.
From the Nokia discussion forums, i learned that the message icon blinking/flashing is caused by SIM messages.
This is a screenshot of the flashing icon,

Goto Menu> Messaging> Options> Sim Messages, and delete all messages there. This solved my problem.

Solving 'classname' followed by 'int' is illegal (did you forget a ';'?) error in C++

2011-02-28T18:13:00.000+05:30

While doing class based programing in C++, the following error occurs.

'classname' followed by 'int' is illegal (did you forget a ';'?)

The error occurs if the class declaration is not terminated properly.
Class declarations should end with a semicolon.

In the above program, the class terminates near the yellow marking, but a semicolon is missing.
Remember that the same structure of a "struct" is used for classes too. Structures end with a semicolon,similarly classes should also end with a semicolon.

Images in addon domains not loading

2011-02-16T11:31:00.000+05:30

While hosting addon domains on hosting with Cpanel, the images in the addon domains may not load.This is due to configuration problems on the server. To fix this, just disable "Hot Link Protection" in Cpanel.
I discovered this solution while troubleshooting a problem for a friend.

A client's domain name, vasantravels.com was added as a addon domain to their primary hosting account that was bought with "square brothers". But, when the page was loaded, it looked like the image below, without any images.

After hanging around with the DNS settings and file names for few days, finally found out that "Hot link protection" is the culprit.
To disable "Hot link protection", goto domainname.com/cpanel and login with username and password.
Find the "Hot link protection" icon on the interface, as shown below.

After opening the "Hot link protection" page, disable the feature.

Finally, all is well, and the site loaded well.
Replicate this procedure if you were having trouble with images from add on domains not loading properly.

Turn off wifi in Nokia c6

2011-02-15T20:51:00.000+05:30

Nokia c6 (nokia 5800) and most symbian phones with WLAN (Wifi) capability connects to wifi automatically most of the time. This causes significant battery drain and reduces the standby time of the phone. The reason for nokia phones to connect to wifi all the time is because of the Email client int he phone.
By default, when we setup a Email profile, the settings are such that the phone connects to a wifi network whenever one is available and configured.
The phone connects again even if we disconnect manually in the settings menu.
Follow this procedure to turn off the wifi automatic connection and to preserve standby time.

Open the Email application, Goto Settings and select the profile name.

In Synchronisation, select "Retrieval days".

Deselect all the days and select OK.

Hereafter, the phone will not connect to wifi automatically. You can still retrieve the emails manually.Also, while sending an email, wifi will connect and send the mail ,then it will disconnect.

List of bugs in Nokia C6

2011-02-15T19:50:00.003+05:30

The purpose of this post is to list all the bugs that i have encountered in my Nokia C6 phone which i bought two months back. All these bugs are persistent and keep bugging me often.I have already installed all available firmware updates.

1. On startup, phone displays the error message "System Error". This error message occurs every time the phone is restarted.

2.When Maps is minimized and opened again, i get the error "Not enough memory to perform operation".

3.When maps is not properly closed,and i open it again, nothing happens. I have to restart the phone to fix this bug.

4.While composing and sending a message, when i click the Send button, the phone gives the error "Unable to send".This happens at least twice daily. If this error occurs, it is not possible to send the message again.Nothing happens if i send again.Phone just says "Sending" and does nothing.It is not even possible to save the typed message.If i save in drafts, it will be saved as an empty message only. The only option to save the typed data is to copy/paste from the message screen. This error is a very annoying one.

5.Wifi stays ON all the time wasting phone battery charge.Once i configure the wifi, it connects even if i manually go to Settings->Connectivity->WLAN->Wifi hotspot->Disconnect. I got tired of manually disconnecting, only to find that it connects after a few minutes again without my permission.There should be option to turn OFF wifi.

Nokia C6 always ON wifi

Update: This problem was due to a configuration error.See this article, Turn off wifi in Nokia phone.

6. Sometimes, while making a call from the inbox by selecting a message and clicking the green call button, phone says "Call not allowed".If this happens, the only way to recover from this error is to restart the phone, otherwise it keeps on giving the same error message.

7. GPS fails to connect most of the times. Only after repeated attempts at restarting and reopening Maps, GPS connects.

//Screenshots not available for all bugs since they are not easy to replicate.

With Nokia favoring Windows platform, it remains to be seen whether the already neglected Symbian platform will get any attention, if at all , from Nokia.

LiveScience.com appears to be hacked and taken down for maintenance

2011-01-15T19:36:00.003+05:30

7:00 PM 1/15/2011 Indian Standard Time
Was trying to visit livescience.com to catch up some interesting science news.
The site said it was down for maintenance!

No one takes a complete website offline for maintenance, atleast they will supply a cached copy online while major maintenance is done in the back end.

So, i googled livescience.com and got into the recent version of the site on Google's cache.
None of the links worked.All turned up 404.Something's fishy here.
Visiting livescience.com/technology provides this,

Lets confirm the 404 from another proxy.

I googled the links rather than visiting the 404 pages.
Google tells that the links may harm my computer.

That's all the evidence.
Now,lets jump to conclusion.

Livescience.com may have been a target of malware infection ,which could have occurred by tapping into vulnerabilities like XSS or any other hacking method.
Then livescience could have started to distribute malware,which maybe the only reason for the "harmful site" warning by google.
Then livescience might have noticed this infection and immediately taken their site completely offline to avoid infecting their visitors.

As we speak,err,type, people at livescience could be working hard to clean up the infection and bring up the site back online.

Thought of covering this story since this news isn't on any other website.
Will report as soon as livescience is back.

Growing cocoa trees in tamil nadu

2010-11-20T17:17:00.001+05:30

Worldwide, there is a huge demand for cocoa and this demand is going to explode in the coming years.
Dr shapiro of IBM research labs says,(BBC ink)

"In late 2007, it became very apparent to me that we would not have a continuous supply of cocoa going into the future if we did not intervene on a massive scale to secure our supply chain."

Vietnamese farmers' success story with the Cocoa plant. (link)

Almost ripe cocoa beans on a 3 year old tree. Persistent international demand has pushed up prices, and farmers are increasingly relying on the crop.
“A 1000 dollar investment in cocoa saplings can gain a yield for the farmers after 2-3 years of 6000 dollars”

Cocoa cultivating farmer testimonial from tamilnadu, video link.

The tamilnadu agriculture minister stated this in 2009,(The Hindu article link)

“The State produces just 200 kg of cocoa seeds per annum while the neighbouring states such as Karnataka (8,000 tonnes), Kerala (7,000) and Andhra Pradesh (2,500) produce much more. We need to improve this,” he insisted.

Mr. Arumugam said that cocoa could generate revenue of Rs. 1.10 lakh per hectare per annum for which the expenditure was Rs. 15,000.

This page provides the list of nurseries in Tamilnadu, some of them may sell cocoa seeds for planting.

Moreover, TN govt has signed up an MOU with Cadbury to distribute seeds to farmers at very affordable price and also provide technical assistance to the growers.That means Cadbury themselves would buy the produced seeds from the farmers. (Article link)

All these mean that TN farmers can grow cocoa plants within coconut farms and arcanut farms.

This government website provides complete details about planting and maintenance stuff.

Nokia c6 review: c6 switches off automatically

2010-10-09T01:33:00.003+05:30

Just bought this Nokia c6 phone few days back,at Chennai,India for 14,000 INR.
Its got good features.
Symbian,Touch screen,5MP camera,WIFI,GPS,3G,front camera for video call, S60 v5,sliding QWERTY keyboard.All is well.
But its too buggy to use.
Infact, the phone got switched off automatically in the phone shop itself.
Those sales people told that its because of low battery charge.
But,the phone continues to shut down by itself every 1hour or so even in battery is fully charged.
Been using this phone for few days and the problem persists.
The only option to restart the phone is to remove the battery and then insert and start.
Its most likely that its a software error(or a hardware bug) that prevents the mobile from a soft restart.
There are no available software updates to fix this issue.
Its very unpleasant to note that this problem ooccured out of the box.One has to wonder about the Quality control within Nokia.
The last option is to take this to the nokia service center.
Will update this post after taking this issue up with Nokia care.

Update 1:
Been to the service center,they flashed the phone and returned it in a day.But the problem persists.Again took the mobile to Nokia care,this time they asked that the mobile be kept in observation for two days.
To be updated soon.
Update:
Apparently, this bug affects many people as well.
Here's lots of people complaining about the mobile at Nokia Forums.

Final Update :
Nokia replaced the motherboard of the mobile after a week and the problem is fixed now. C6 is now running perfectly for nearly a month.
