Foods That Reduce LDL Cholesterol in Your Body

2013-01-08T09:37:00.000-08:00

There are basically two different types of lipoproteins that carry cholesterol in your body. They are high-density lipoproteins (HDL) and also low-density lipoproteins (LDL). Generally, HDL is also known as good cholesterol as it transports cholesterol from your whole body to your liver where the cholesterol is removed. On the other hand, LDL is usually labeled as bad cholesterol as high levels can clot the arteries.

1. Oat Bran and Oatmeal
- Oatmeal is high in soluble fiber, which is effective in reducing the bad cholesterol levels. This type of dietary fiber can also be found abundantly in foods like barley, prunes, pears and apples. Soluble fiber helps block cholesterol absorption into your blood. According to studies, by taking 5 to 10 grams of soluble fiber daily is sufficient to lower your LDL cholesterol and the total cholesterol in whole. One and a half cups of oatmeal give you 6 grams of food fiber.

2. Fish
- Fish is a good source of Omega-3 fatty acids, especially halibut, herring, lake trout mackerel, salmon and tuna. Therefore, it is an excellent food to help decrease your cholesterol levels and promote a healthy heart. In order to control your blood pressure and protect yourself from clots in the bloodstream, fish with good amount of Omega-3 fatty acids is a wonderful choice. For people with heart disease, Omega-3 fatty acids protect them against sudden death due to heart attack. Furthermore, these fatty acids are also capable of increasing HDL cholesterol or good cholesterol in your body.

3. Nuts
- Nuts like almonds, hazelnuts, pistachios, pecans and walnuts are brilliant in reducing triglycerides. There are some incredible compounds in them that are transformed into Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) -- two types of Omega-3 fatty acids -- in your body. According to Food and Drug Administration (FDA), intake of 1 1/2 ounces of various nuts every day helps reduce the risk of developing heart disease.

4. Blueberries
- Blueberries contain a compound known as Pterostilbene, which is a natural remedy to cut down LDL cholesterol levels with no unwanted side effects. Anthocyanins, an antioxidant found substantially in blueberries, are also effective in lowering LDL cholesterol and balance up your overall cholesterol levels.

5. Green Tea
- Scientific studies have found that green tea help lower overall cholesterol and LDL in particular. As reported by Reuters in November 2011, a study in the United States that has over a thousand participants has shown that green tea helps lower bad cholesterol readings, when drunk as beverage or taken in a capsule. However, scientists have found no evidence that green tea helps increase HDL cholesterol or reduce triglycerides. — with Anlyn Quelitano, Ashutosh Batish, Himanshu Lall and 12 others.

Alternative Way to Elimate Cancer from Johns Hopkins

2013-01-08T08:54:00.002-08:00

After years of telling people Chemotherapy is the only way to try and eliminate cancer, Johns Hopkins is finally starting to tell you there is an alternative way.

1. Every person has cancer cells in the body. These cancer cells do not show up in the standard tests until they have multiplied to a few billion. When doctors tell cancer patients that there are no more cancer cells in their bodies after treatment, it just means the tests are unable to detect the cancer cells because they have not reached the detectable size.

2. Cancer cells occur between 6 to more than 10 times in a person's lifetime.

3. When the person's immune system is strong the cancer cells will be destroyed and prevented from multiplying and forming tumors.

4. When a person has cancer it indicates the person has multiple nutritional deficiencies. These could be due to genetic, environmental, food and lifestyle factors.

5. To overcome the multiple nutritional deficiencies, changing diet and including supplements will strengthen the immune system.

6. Chemotherapy involves poisoning the rapidly-growing cancer cells and also destroys rapidly-growing healthy cells in the bone marrow, gastro-intestinal tract etc, and can cause organ damage, like liver, kidneys, heart, lungs etc.

7. Radiation while destroying cancer cells also burns, scars and damages healthy cells, tissues and organs.

8. Initial treatment with chemotherapy and radiation will often reduce tumor size. However prolonged use of chemotherapy and radiation do not result in more tumor destruction.

9. When the body has too much toxic burden from chemotherapy and radiation the immune system is either compromised or destroyed, hence the person can succumb to various kinds of infections and complications.

10. Chemotherapy and radiation can cause cancer cells to mutate and become resistant and difficult to destroy. Surgery can also cause cancer cells to spread to other sites.

11. An effective way to battle cancer is to STARVE the cancer cells by not feeding it with foods it needs to multiple.

What cancer cells feed on:

a. Sugar is a cancer-feeder. By cutting off sugar it cuts off one important food supply to the cancer cells. Note: Sugar substitutes like NutraSweet, Equal, Spoonful, etc are made with Aspartame and it is harmful. A better natural substitute would be Manuka honey or molasses but only in very small amounts. Table salt has a chemical added to make it white in colour. Better alternative is Bragg's aminos or sea salt.

b. Milk causes the body to produce mucus, especially in the gastro-intestinal tract. Cancer feeds on mucus. By cutting off milk and substituting with unsweetened soy milk, cancer cells will starved.

c. Cancer cells thrive in an acid environment. A meat-based diet is acidic and it is best to eat fish, and a little chicken rather than beef or pork. Meat also contains livestock antibiotics, growth hormones and parasites, which are all harmful, especially to people with cancer.

d. A diet made of 80% fresh vegetables and juice, whole grains, seeds, nuts and a little fruits help put the body into an alkaline environment. About 20% can be from cooked food including beans. Fresh vegetable juices provide live enzymes that are easily absorbed and reach down to cellular levels within 15 minutes t o nourish and enhance growth of healthy cells.

To obtain live enzymes for building healthy cells try and drink fresh vegetable juice (most vegetables including bean sprouts) and eat some raw vegetables 2 or 3 times a day. Enzymes are destroyed at temperatures of 104 degrees F (40 degrees C).

e. Avoid coffee, tea, and chocolate, which have high caffeine. Green tea is a better alternative and has cancer-fighting properties. Water--best to drink purified water, or filtered, to avoid known toxins and heavy metals in tap water. Distilled water is acidic, avoid it.

12. Meat protein is difficult to digest and requires a lot of digestive enzymes. Undigested meat remaining in the intestines will become putrified and leads to more toxic buildup.

13. Cancer cell walls have a tough protein covering. By refraining from or eating less meat it frees more enzymes to attack the protein walls of cancer cells and allows the body's killer cells to destroy the cancer cells.

14. Some supplements build up the immune system (IP6, Flor-ssence, Essiac, anti-oxidants, vitamins, minerals, EFAs etc.) to enable the body's own killer cells to destroy cancer cells. Other supplements like vitamin E are known to cause apoptosis, or programmed cell death, the body's normal method of disposing of damaged, unwanted, or unneeded cells.

15. Cancer is a disease of the mind, body, and spirit. A proactive and positive spirit will help the cancer warrior be a survivor.

Anger, unforgiving and bitterness put the body into a stressful and acidic environment. Learn to have a loving and forgiving spirit. Learn to relax and enjoy life.

16. Cancer cells cannot thrive in an oxygenated environment. Exercising daily, and deep breathing help to get more oxygen down to the cellular level. Oxygen therapy is another means employed to destroy cancer cells.

Brain Damaging Habits

2011-12-16T22:46:00.000-08:00

A very good article on the common mistakes we do which causes Brain Damages.

No Breakfast

People who do not take breakfast are going to have a lower blood sugar level. This leads to an insufficient supply of nutrients to the brain causing brain degeneration.

Overeating

It causes hardening of the brain arteries, leading to a decrease in mental power.

Smoking

It causes multiple brain shrinkage and may lead to Alzheimer disease.

High Sugar consumption

Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development.

Air Pollution

The brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain, bringing about a decrease in brain efficiency.

Sleep Deprivation

Sleep allows our brain to rest. Long term deprivation from sleep will accelerate the death of brain cells.

Head covered while sleeping

Sleeping with the head covered increases the concentration of carbon dioxide and decrease concentration of oxygen that may lead to brain damaging effects.

Working your brain during illness

Working hard or studying with sickness may lead to a decrease in effectiveness of the brain as well as damage the brain.

Lacking in stimulating thoughts

Thinking is the best way to train our brain, lacking in brain stimulation thoughts may cause brain shrinkage.

Talking Rarely

Intellectual conversations will promote the efficiency of the brain.

To all Guys... Don't sit on your wallet !!!

2011-06-26T11:53:00.000-07:00

Your wallet can be real pain for your back and the buttocks, and it can even lead to shooting pains down the legs. Sitting on a wallet for prolonged hours every day can compress sciatic nerve which passes beneath piriformis muscle and leads to piriformis syndrome, low back pain & self-inflicted sciatica.

The wallet acts as a wedge that forces the pelvis, spine and body out of alignment. Just as you would not sit on a brief case or a rock for an extended period of time, you should not sit on your wallet. Anyone who drives more than a half hour sitting on a wallet is a candidate for sciatica or back pain.

The healthiest option is to move the wallet to your front pocket. If it’s must to keep your wallet in your back pocket, you should remove it before you sit down.

Heart Attacks And Drinking Warm Water

2011-06-26T11:37:00.000-07:00

Very good article, which takes two minutes to read.

This is a very good article. Not only about the warm water after your meal, but about Heart Attacks. The Chinese and Japanese drink hot tea with their meals, not cold water, maybe it is time we adopt their drinking habit while eating.

For those who like to drink cold water, this article is applicable to you. It is nice to have a cup of cold drink after a meal. However, the cold water will solidify the oily stuff that you have just consumed. It will slow down the digestion. Once this 'sludge' reacts with the acid, it will break down and be absorbed by the intestine faster than the solid food. It will line the intestine. Very soon, this will turn into fats and lead to cancer.

It is best to drink hot soup or warm water after a meal.

Common Symptoms Of Heart Attack...
A serious note about heart attacks - You should know that not every heart attack symptom is going to be the left arm hurting. Be aware of intense pain in the jaw line.

You may never have the first chest pain during the course of a heart attack.Nausea and intense sweating are also common symptoms. 60% of people who have a heart attack while they are asleep do not wake up.. Pain in the jaw can wake you from a sound sleep. Let's be careful and be aware. The more we know, the better chance we could survive.

A cardiologist says if everyone who reads this message shares it with other friends on twitter, Facebook etc., you can be sure that we'll save at least one life. Read this & Share to a friend. It could save a life...So, please be a true friend and send this article to all your friends you care about.

Correct timing to drink water, will maximize its effectiveness on the Human body.
Two (02) glass es of water - After waking up - Helps activate internal organs
One (01) glass of water - 30 minutes before meal - Help digestion
One (01) glass of water - Before taking a bath - Helps lower blood pressure
One (01) glass of water - Before sleep - To avoid stroke or heart attack

Please pass this to the people you know....... I JUST DID!!!

Handling Multiple Images Upload - PHP Mysql

2011-05-04T01:40:00.000-07:00

First you need to create File Upload form,

Use the following html form,

Choose a file to upload : <input type="hidden" name="MAX_FILE_SIZE" value="100000"><input name="uploadedfile" type="file">

</form>

Use the following in the Action PHP script,

if($_POST){

if (!empty($_FILES['uploadedfile']['name']){

$imageType = $_FILES['uploadedfile']['type'];

if($imageType == "image/jpeg" || $imageType == "image/png" || $imageType == "image/gif") {

$target_path = getcwd() . "/uploads/";

$randNum = rand(1000, 9999);

$imageName = date("YmdHis") . "-" . $randNum . ".jpg";

$target_path = $target_path . $imageName;

if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {

echo "<script type='text/javascript'>

alert('Image uploaded successfully. Click here to continue!');

window.location = 'index.php';

</script>";

} else {

$cardInsertResponse = "There was an error uploading the file, please try again!";

}

If there is a requirement to handle large number of images, we have two options to store the images

Store the raw images at the Database
Store images at separate folder and only store the image path at Database

Here we are using the Second option, due to the following reasons,

Assuming Image of Maximum 100KB, with 10 images we need to have 1 MB of database capacity
Retrieving an image from a database incurs significant overhead compared to using the file system.
Disk storage on database is typically more expensive than storage on disks

SSH and Screen - Useful Tips

2011-05-03T23:14:00.000-07:00

Screen is very useful in running processes despite losing connection to remote server connected with SSH. The detached process could be attached to the terminal and we could continue the work at later stage. This will show you how to use screen utility.

On Debian and Ubuntu, you just run the following command to install screen.

apt-get install screen

To Start a new screen session just type the following command in ssh terminal

screen

To Start a new screen session with user defined session name

screen -S sessionname

More commands for screen

Ctrl a c - Creates a new screen session so that you can use more than one screen session at once

Ctrl a n - Switches to the next screen session (if you use more than one)

Ctrl a p - Switches to the previous screen session (if you use more than one)

Ctrl a d - Detaches a screen session (without killing the processes in it - they continue)

Use the following command to close screen session once all the tasks done,

exit

To browse two or more screens,

Ctrl a n / Ctrl a p

To view all the detached screen sessions, type the following on the normal SSH terminal,

screen -ls

Assume we have two screen Sessions as below, which could be viewed from screen -ls command,

There are screens on:
2477.pts-0.server1 (Detached)
2522.pts-0.server1 (Detached)
2 Sockets in /var/run/screen/S-root.

To reconnect to one of the screen session,

screen -r 2477.pts-0.server1

To close the session,

exit

World's First Programmable Nanoprocessor

2011-02-11T11:27:00.000-08:00

While Studying at University, I had an opportunity to take up Nanotechnology as a Subject for my Final Year. I was also part of the Team which put up the First Nano Stall in Sri Lanka. Coming to the topic, No Microprocessors, Its *Nanoprocessors*.

ALU functionalities performed at Atomic scale. That's right!!!

1 nm ~ 10 * (width of Hydrogen Atom)

This is a electron microscopy image of a programmable nanowire nanoprocessor super-imposed on a schematic nanoprocessor circuit architecture. (Credit: Photo courtesy of Charles M. Lieber, Harvard University.)

This Work done by Researchers at Harvard University and MITRE's Nanosystems Group. They have come up with Detail Architecture of Programmable Nanoprocessor built out of Nanowires.

As many of you don't know, Nanotechnology has come a long way and It is usually has Top-Down or Bottom-Up approach. Mostly Top down approach is used where you use Chemical Reactions at Nanoscale to form up the required Functionality.

But the difficult and still at research level is the Bottom-Up Approach. It is the Concept of building anything from Atom by Atom. Forming a full structure from atoms.

Conceptual Nano Factory Video:

"This new nanoprocessor represents a major milestone toward realizing the vision of a nanocomputer that was first articulated more than 50 years ago by physicist Richard Feynman." says James Ellenbogen, a chief scientist at MITRE

Black Seed - Health Benefits and How to Use ?

2010-12-16T00:45:00.000-08:00

I got this information from a very close friend of mine. After doing some background research I found some very useful and interesting information. So I am writing this blog post so that it will benefit everyone. If you find it interesting and helpful, please click like in the post and share it with your friends.

Black seed (Nigella sativa) (கருஞ்சீரகம்) is considered to be one of the greatest healing herbs of all times. This herb has been used for thousands of years to strengthen the immune system, cleanse the body, purify the blood, protect against irritants and support healthy longevity. Long forgotten this herb is now enjoying a positive and welcomed come-back.

The power of 'Black seed' lies in the ingredients Nigella and Melatin found in Black seed. There are about 100 different chemical compounds or valuable nutrients found in Black seed.

Black Seed has over 1400 years history of use. Many ancient books and text suggest the following traditional uses for Black Seed. But please note, that these should not be understood as cures or treatments for any disease or illness.

How does Black Seed Benefit ?

The majority of our health problems have the same causes- infection by micro-organisms such as bacteria, viruses, parasites and fungi. When using clinical (allopathic medicines) each symptom is treated individually and usually with synthetic chemically manufactured medicines that contain alcohol and other harmful ingredients. Black seed is effective at treating the body as a whole and fights the actual cause of the symptoms. Black seed regulates too weak or too strong reactions of the immune system and is excellent for treating chronic, allergic and hormonal diseases.It uses are many as well as its benefit. Black seed support metabolism, improve digestion, and lowers blood sugar levels. It is used to dispel worms and parasites from intestinal track. It is useful in soothing bronchitis and coughs,increase body tone, stimulates menstrual periods, increases the flow of breast milk, provides quick energy, increases sperm count, calms the nervous system, encourages hair growth and retards hair fall out, prevents skin wrinkling, and much more.

Side Effects of Black Seeds

There are no known side effects of this miraculous herb, but it is better to take caution here. Black Seed has been reported to be toxic in the amount of 25 grams or more. But who in the world would take that amount? The maximum dosage for any cure is 3 teaspoons per day. Some sites are telling people to take a large amount of the oil, to sell more products. Follow the suggested dosage requirements, and see that more is not necessary and more does not heal quicker.

Warnings of Black Seeds

Never take the oil on a full stomach. It needs to be mixed with another liquid such as juice, yogurt or honey and taken one hour before the meal. If taking the oil twice in a day, then the oil should be mixed with honey or juice and taken before bedtime.
If taking the seeds, they must be heated. Never take the seeds that have not been heated as they will upset the stomach.

How to Heat the Seeds

Place one fourth of the seeds in a skillet on low heat. Use only one fourth of the seeds in case the seeds are burned. Stir the seeds every few minutes and keep tasting the seeds until they loose their tart taste. The seeds must be bland. The seeds should pop slightly. Remove them from the heat and let them cool. Place the desired amount in a coffee grinder and grind. Place the desired seeds in vegetarian capsules or in honey.

How to Mix the Seeds with the Honey

Fill a pint jar with the ground black seeds and add in one fourth a jar of honey. Mix the honey and the black seeds well. Keep adding a little honey at a time until the honey and black seeds are mixed well. It needs to be a very thick consistency. The mixture will thicken more over night. It is very delicious and a sweet treat. Suggested dosage is one teaspoon a day. Do not give the honey mixture to diabetic patients.

Precautions for the Use of Black Seeds

It is not suggested for pregnant women to take black seeds. If the patient has a major disease, they need to be monitored by a doctor as black seeds will cause your blood pressure to drop.
Never mix black seeds with pharmaceutical medicines. Some sites are stating the opposite, but it is not a Cure when the Black seed is mixed with another ingredient.The cure only works with faith and sincerity. Not believing in the cure is the same as not having a cure at all.

Apache log4cxx framework - Example using Pthreads - Part Two

2010-10-11T04:43:00.000-07:00

This blog post is continued from Apache log4cxx framework - Part One

This post comprises of a simple Configuration file and how it can be incorporated to a c++ code file for using the log4cxx framework.

Add the following simple xml Configuration file and name it as "MyLog4CxxConfig.xml"

<?xml version="1.0" encoding="UTF-8" ?>
 <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

  <appender name="ConsoleAppend" class="org.apache.log4j.ConsoleAppender"> 
   <param name="Target" value="System.out"/> 
   <layout class="org.apache.log4j.PatternLayout"> 
    <param name="ConversionPattern" value="%-5p %c{1} - %m%n"/> 
   </layout> 
  </appender> 
 
 
  <appender name="LogFileAppend" class="org.apache.log4j.FileAppender">
   <param name="file" value="MyLogFile.log" />
   <param name="append" value="true" />
   <layout class="org.apache.log4j.PatternLayout"> 
    <param name="ConversionPattern" value="%d %5p %c{1} - %m%n" /> 
   </layout>
  </appender>
 
  <root>
   <priority value="all" />
   <appender-ref ref="ConsoleAppend"/>
  </root> 
 
   <category name="TestFunction" >
   <priority value ="info" />
   <appender-ref ref="LogFileAppend" />
  </category> 
 
 </log4j:configuration>

The above configuration is very simple one and it is supposed to output all the log messages to the console as the Log level is set to "all" and "info" level log messages will be appended to "MyLogFile.log".

Now add "Test.cpp" to your project. This is the simple threaded example for testing log4cxx. Include the following header files 'pthread.h', 'sched.h', 'log4cxx\logger.h', 'log4cxx\xml\domconfigurator.h'

using namespace log4cxx;
using namespace log4cxx::xml;
using namespace log4cxx::helpers;

LoggerPtr MyMainLogger(Logger::getLogger("TestFunction"));

void* TestFunction(void* arg){

    LOG4CXX_INFO(MyMainLogger, "Test Function Started!");

    int data = (int) arg;
    char thread_data[10];
    sprintf(thread_data, "thread - %d", data);

    LOG4CXX_INFO(MyMainLogger, thread_data);
    LOG4CXX_INFO(MyMainLogger, "Test Function Completed!");

}

int main(int argc, char** argv[])
{
    DOMConfigurator::configure("MyLogConfig.xml");

    int my_data, thread_num = 5;
    pthread_t thread_id[thread_num];

    for (int i = 0; i < thread_num; i++) {

        my_data = i;

        if (pthread_create(&(thread_id[i]), NULL, TestFunction, (void *) my_data) == 0) {
        } else {
            LOG4CXX_ERROR(MyMainLogger, "pthread create error.");
            exit(1);
        }
        sched_yield();
    }

    for (int i = 0; i < thread_num; i++) {
        pthread_join(thread_id[i], NULL);
    }
    return 0;
}

The above Test.cpp creates 5 posix threads which executes the TestFunction. When using this sample, please add PThreads Static Library from Netbeans Project properties or add the following line of code "-lpthread" to LDLIBSOPTIONS in the make debug file.

   private $db_name;
   private $connection;

   public function __construct($host = '127.0.0.1', $user = 'root', $pass='', $database_name='mydb') {
   $this->db_host = $host;
   $this->db_user = $user;
   $this->db_pass = $pass;
   $this->db_name = $database_name;
   }

   public function connectDb() {
   $this->connection = mysqli_connect($this->db_host, $this->db_user, $this->db_pass) or die(mysqli_error());
   mysqli_select_db($this->connection, $this->db_name) or die(mysqli_error());
   }

   public function closeConn() {
   if ($this->connection) {
   mysqli_close();
   }
   }

   public function isConnected() {
   if ($this->connection) {
   return true;
   } return
   false;
   }

   public function execute_query($sql) {
   if (!$this->isConnected()) {
   $this->connectDB();
   }
   $result = mysqli_query($this->connection, $sql) or die(mysqli_errno($this->connection));
   return $result;
   }

   public function get_query($sql) {
   if(!$this->isConnected()) {
   $this->connectDb();
   }
   $result = mysqli_query($this->connection, $sql) or die(mysqli_errno($this->connection));

   $resultArray = array();
   $count = 0;
   while ($obj = mysqli_fetch_object($result)) {
   $resultArray[$count] = $obj;
   $count++;
   }
   return $resultArray;
   }

}
?>

Now add MyTable.php Class which represents the 'mytable' database table.

<?php

include_once 'DbConnector.php';

class MytableTable {

private $dbConn;

public function __construct() {

$this->dbConn = new DbConnector();

}

public function insertNew($val) {

$sql = "insert into mytable (col)" .

" values ('$val') ";

return $this->dbConn->execute_query($sql);

}

public function getMytableAll(){

$sql = "select * from mytable";

return $this->dbConn->get_query($sql);

}

Now from your interface you can use the above two php class to add a new entry in mytable or get all the entries from mytable.

Apache log4cxx framework - Part One

2010-10-10T22:15:00.000-07:00

I happened to work with Apache log4cxx, a logging framework for c++. This framework offers lot of capabilities from simply outputting a log message to console, writing to log files, socket streaming and database logging. Best thing that i love about this framework that it is Thread safe.

Apache log4cxx, You can download it here

Log4cxx comprises of three main parts,

1) Public Class Logger
- Top level entry point of Logger

2) Public Interface Appender
- Controlling the Output log operations
3) Public Abstract Class Layout
- Output format

Log Levels

There about 6 levels of Log Levels. They are; TRACE, DEBUG, INFO, WARN, ERROR, FATAL, also there we have another two levels, "ALL" and "OFF".

When configuring you can setup the Log Levels according to the need of the Logger. The following image describes the Log Levels and Log level accessiblity.

Descriptions of each Level:

DEBUG

Informational logs that is useful to debug an application

INFO

Informational logs that are usefull to highlight the progress the application

WARN

Warning logs describing certain application specific other options

ERROR

Error logs describing events which causes application exceptions, but these exceptions are handled and the application can still run continously.

FATAL
Fatal logs describing events which cause severe error and leading to application exit.

Link Library to Netbeans Project
In your Netbeans projects, after the installation of Log4cxx, to link the static library to the project, use the following in the LDLIBSOPTIONS of make debug file.

-I/usr/include pathof(liblog4cxx.a) -lapr-1 -laprutil-1

25 Reasons why you should drink green tea

Green Tea has increasingly become a very popular drink worldwide because of its immensely powerful health benefits. It is extraordinary amazing what green tea can do for your health. And if you're not drinking 3 to 4 cups of green tea today, you're definitely NOT doing your health a big favor. Here are the 25 reasons why you should start drinking green tea.

1. Green Tea and Cancer
Green tea helps reduce the risk of cancer. The antioxidant in green tea is 100 times more effective than vitamin C and 25 times better than vitamin E. This helps your body at protecting cells from damage believed to be linked to cancer.

2. Green Tea and Heart Disease
Green tea helps prevent heart disease and stroke by lowering the level of cholesterol. Even after the heart attack, it prevents cell deaths and speeds up the recovery of heart cells.

3. Green Tea and Anti-Aging
Green tea contains antioxidant known as polyphenols which fight against free radicals. What this means it helps you fight against aging and promotes longevity.

4. Green Tea and Weight Loss
Green tea helps with your body weight loss. Green tea burns fat and boosts your metabolism rate naturally. It can help you burn up to 70 calories in just one day. That translates to 7 pounds in one year.

5. Green Tea and Skin
Antioxidant in green tea protects the skin from the harmful effects of free radicals, which cause wrinkling and skin aging. Green tea also helps fight against skin cancer.

6. Green Tea and Arthritis
Green tea can help prevent and reduce the risk of rheumatoid arthritis. Green tea has benefit for your health as it protects the cartilage by blocking the enzyme that destroys cartilage.

7. Green Tea and Bones
The very key to this is high fluoride content found in green tea. It helps keep your bones strong. If you drink green tea everyday, this will help you preserve your bone density.

8. Green Tea and Cholesterol
Green tea can help lower cholesterol level. It also improves the ratio of good cholesterol to bad cholesterol, by reducing bad cholesterol level.

9. Green Tea and Obesity
Green tea prevents obesity by stopping the movement of glucose in fat cells. If you are on a healthy diet, exercise regularly and drink green tea, it is unlikely you'll be obese.

10. Green Tea and Diabetes
Green tea improves lipid and glucose metabolisms, prevent sharp increases in blood sugar level, and balance your metabolism rate.

11. Green Tea and Alzheimer's
Green tea helps boost your memory. And although there's no cure for Alzheimer's, it helps slow the process of reduced acetylcholine in the brain, which leads to Alzheimer's.

12. Green Tea and Parkinson's
Antioxidants in green tea helps prevent against cell damage in the brain, which could cause Parkinson's. People drinking green tea also are less likely to progress with Parkinson's.

13. Green Tea and Liver Disease
Green Tea helps prevent transplant failure in people with liver failure. Researches showed that green tea destroys harmful free radicals in fatty livers.

14. Green Tea and High Blood Pressure
Green tea helps prevent high blood pressure. Drinking green tea helps keep your blood pressure down by repressing angiotensin, which leads to high blood pressure.

15. Green Tea and Food Poisoning
Catechin found in green tea can kill bacteria which caused food poisoning and kills the toxins produced by those bacteria.

16. Green Tea and Blood Sugar
Blood sugar tends to increase with age, but polyphenols and polysaccharides in green tea help lower your blood sugar level.

17. Green Tea and Immunity

Scientists in Japan have found that EGCG (Epigallocatechin Gallate) in green tea can stop HIV from binding to healty immune cells. What this means is that grean tea can help stop the HIV virus from spreading.

How to TripleDES encrypt decrypt data? - Part Two

2010-04-23T03:50:00.000-07:00

This post has reference to part one of this Article.

Inside our "TripleDESCrypt" class, lets implement another method to read the MD5 HashKey generated from the Secret Key from the User. This method will load the TripleDESKey.xml file and returns the HashKey in String format.

private string GetXmlKey(string xmlPath)
{
     string hashKey = "";
     try
     {
           XDocument doc = XDocument.Load(xmlPath);
           hashKey = doc.Descendants("key").ElementAt(0).Value;
      }
      catch(SystemException)
      {
          throw new Exception("Xml Document Load Error");
      }

return hashKey;
}

Include the below method to create the TripleDES object from Hashkey.

private TripleDES CreateDES(string hashKey)
{
      TripleDES des = new TripleDESCryptoServiceProvider();
      des.Key = Convert.FromBase64String(hashKey);
      des.IV = new byte[des.BlockSize / 8];
      return des;
}

Include the following two methods inside the "TripleDESCrypt" class, these two methods will be used to Encrypt and Decrypt user input data respectively.

public string EncryptData(string Data)
{
      string key = GetXmlKey(myPath);

      TripleDES des = CreateDES(key);
       ICryptoTransform ct = des.CreateEncryptor();
       byte[] input = Encoding.Unicode.GetBytes(Data);

       byte[] output = ct.TransformFinalBlock(input, 0, input.Length);

        return Convert.ToBase64String(output);
}

public string DecryptData(string Data)
{
       string key = GetXmlKey(myPath);

       byte[] input = Convert.FromBase64String(Data);

       TripleDES des = CreateDES(key);
       ICryptoTransform ct = des.CreateDecryptor();

       byte[] output = ct.TransformFinalBlock(input, 0, input.Length);

        return Encoding.Unicode.GetString(output);
}

Now, inside the Aspx page, add the below two lines of code to test the Encryption and Decryption using TripleDES.

string EncryptData = my3DES.EncryptData("Your Data");
string DecryptData = my3DES.DecryptData(EncryptData);

How to TripleDES encrypt decrypt data? - Part One

2010-04-23T03:22:00.000-07:00

In this post, a simple demonstration of how TripleDES Encryption algorithm can be implemented using System.Security.Cryptography namespace in .NET will be explained.

First of all, we need to create a XML file where we will be storing our Special Key. This Key will be used for both Encryption and Decryption not like RSA. DES is symmetric key encryption algorithm.

This special Key will be generated using MD5, which is a cryptographic hash function which takes arbitrary block of data and returns a Stream of Bits of Fixed Length.

Create a Simple Web Application and create a New Class with the name "TripleDESCrypt".

Assume we have TripleDESKey.xml in our same Application Folder. Lets create a method to update the path variable from Aspx page. Include the following in "TripleDESCrypt" class.

public static string myPath = "";

public void updateXmlPath(string xmlPath)
{
myPath = xmlPath;
}

Now, include the below method in our "TripleDESCrypt" class. This method will be used to create 16-Byte Key using MD5 and this Special Key will be saved in our TripleDESKey.xml file.

public void GenerateMD5HashKey(string word)
{
       MD5 md5 = new MD5CryptoServiceProvider();
       byte[] hashKey = md5.ComputeHash(Encoding.Unicode.GetBytes(word));
       string sss = Convert.ToBase64String(hashKey);

       XElement ele = new XElement("key", sss);
       ele.Save(myPath);
}

To implement this, include the below lines of code in Page Load method of Aspx Page. Below the Secret Key that the user inputs will be converted to MD5 HashKey and will be saved in the XML file.

TripleDESCrypt my3DES = new TripleDESCrypt();
my3DES.updateXmlPath(Server.MapPath("TripleDESKey.xml"));

my3DES.GenerateMD5HashKey("Your Secret Key");

How to RSA Encrypt Decrypt Data (C#) ?

2010-04-19T01:46:00.000-07:00

This post has reference to part one of this Article.

Inside our "Crypt" class, lets include two more methods.

public string EncryptData(string data2Encrypt)
{
      ParameterSetup();
      StreamReader reader = new StreamReader(publicPath);
      string publicOnlyKeyXML = reader.ReadToEnd();
      rsa.FromXmlString(publicOnlyKeyXML);
      reader.Close();

      //encrypt
      byte[] plainbytes = System.Text.Encoding.UTF8.GetBytes(data2Encrypt);
      byte[] cipherbytes = rsa.Encrypt(plainbytes, false);
      return Convert.ToBase64String(cipherbytes);
}

public string DecryptData(string data2Decrypt)
{
      ParameterSetup();

      byte[] getpassword = Convert.FromBase64String(data2Decrypt);

      StreamReader reader = new StreamReader(privatePath);
      string publicPrivateKeyXML = reader.ReadToEnd();
      rsa.FromXmlString(publicPrivateKeyXML);
      reader.Close();

      //decrypt
      byte[] plain = rsa.Decrypt(getpassword, false);
      return System.Text.Encoding.UTF8.GetString(plain);
}

Now from Aspx page you can use these methods as follows,

Crypt myCrypt = new Crypt();
myCrypt.updatePrivatePath(Server.MapPath("PrivateKey.xml"));
myCrypt.updatePublicPath(Server.MapPath("PublicKey.xml"));

myCrypt.GenerateKey();

string EncryptData = myCrypt.EncryptData("Your Name");
string DecryptData = myCrypt.DecryptData(EncryptData);

How to Generate RSA Encryption keys (C#) ?

2010-04-19T01:00:00.000-07:00

In this post, Simple Demonstration of RSA Encryption Algorithm will be explained.

Here, we are going to make use of the System.Security.Cryptography namespace.

Now, Lets create two XML files, PrivateKey.xml and PublicKey.xml. In these files we will be storing the Private Key and Public Key respectively.

Usually, the Public Key is available publically but the Private key will be kept in a Secret Location. Data Encrypted using the Public Key can only be decrypted using Private Key. Basically, Private key is the full Key and Public Key is part of the Private Key. So even with just Public key, you can't decrypt the Data. So it provides Full Protection and Data Security.

Create a Simple Web Application and create a New Class with the name "Crypt".

Assume we have both the PrivateKey.xml and PublicKey.xml in our same Application Folder. Lets create few methods to update two string variables that represent the path of PrivateKey.xml and PublicKey.xml from Aspx page. Include the following in "Crypt" class

private static string privatePath = "";

public static string publicPath = "";

public void updatePrivatePath(string xmlPath) {
privatePath = xmlPath;

}

public void updatePublicPath(string xmlPath) {
publicPath = xmlPath;
}

Include the following to update from Page Load method of Aspx Page.

Crypt myCrypt = new Crypt();

myCrypt.updatePrivatePath(Server.MapPath("PrivateKey.xml"));

myCrypt.updatePublicPath(Server.MapPath("PublicKey.xml"));

Add the following public variable in the "Crypt" class

public static RSACryptoServiceProvider rsa;

Now lets implement Private and Public Key Generation. Include the following in the "Crypt" class.

private void ParameterSetup()

{
    CspParameters cspParams;
    cspParams = new CspParameters(1, "Microsoft Strong Cryptographic Provider", "MyContainer");
    cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
    rsa = new RSACryptoServiceProvider(cspParams);

}

public void GenerateKey()

{
     ParameterSetup();

    //Write Public and Private Key
    StreamWriter writer = new StreamWriter(privatePath);
    string publicPrivateKeyXML = rsa.ToXmlString(true);
    writer.Write(publicPrivateKeyXML);
    writer.Close();

    //Write Public Key only
    writer = new StreamWriter(publicPath);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    writer.Write(publicOnlyKeyXML);
    writer.Close();

}

Now from Aspx page, you can update the path and Call the GenerateKey method as below,

Crypt myCrypt = new Crypt();

myCrypt.updatePrivatePath(Server.MapPath("PrivateKey.xml"));

myCrypt.updatePublicPath(Server.MapPath("PublicKey.xml"));

myCrypt.GenerateKey();

Now you can check your Xml files to have a look at your Public and Private keys.
Next Part, we will look at how to Encrypt and Decrypt using RSA asymmetric encryption algorithm.

How to convert Image format programmatically (.NET) ?

2010-03-26T00:19:00.000-07:00

To convert an Image from one format to another, use the following Method.
Here, the known formats include, Bmp, Emf, Exif, Gif, Icon, Jpeg, Png, Tiff, Wmf etc.

First, include the following Namespaces;

using System.IO.Path;
using System.Drawing.Imaging;

Now assume you have Tiff image file in the following directory,

C:/Temp/myImage.tif

Assume you want to convert it to png and save it in the same directory, just use the below line of code in your project.

ConvertImageFormat("C:/Temp/myImage.tif", ImageFormat.Png)

The implementation of the above method is given below,

private bool ConvertImageFormat(String imagepath, ImageFormat format)
{

   bool status = false;
   string newfile;

   try {
                Bitmap obj = new Bitmap(imagepath);
                newfile = GetDirectoryName(imagepath) + "\\"
                                      + GetFileNameWithoutExtension(imagepath) + "."
                                                                                                 + format.ToString();

                obj.Save(newfile, format);
                obj.Dispose();
                status = true;
   }
   catch(SystemException) {
   }
   return status;
}

WCF and HTTP Error 404.3

2010-03-16T23:01:00.000-07:00

Once you create a WCF Service from Visual Studio 2008 and after publishing to IIS, when you browse your Service, you will receive HTTP 404.3 Error. But you will not find any discrepancies in IIS Configuration of the Service.

This is due to Windows Service of Microsoft .NET Framework 3.0 not fully installed (not activated the WCF Windows Services) and not because of Windows Service of IIS. So follow the below procedure if you are using Windows, Vista and for different operating systems, it is found in different locations.

Vista : Control Panel -> Program and Features -> Turn on/ off Windows Features -> Microsoft.NET Framework 3.0

Now, Install the following Components.

Windows Communication Foundation HTTP Activation
Windows Communication Foundation Non-HTTP Activation

You can do the installation manually by running "ServiceModelReg.exe", which was found at %Windows%\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\

Most Insane Coincidences You Won't Believe Actually Happened

2010-03-15T03:13:00.000-07:00

I read an interesting Blog about Six insane coincidences and I have selected two most striking and amazing out of the six. I would like to share in my blog as well because its just awesome. Just read and see...

A Terrifyingly Accurate Prediction by Edgar Allan Poe

In 1838, future horror-god "Edgar Allan Poe" released a book called The Narrative of Arthur Gordon Pym of Nantucket, his only full novel. The book was such a bomb that Poe eventually agreed with his critics that it was "a very silly book".

Where it Gets Weird:

Poe did a Blair Witch thing with his novel, which claimed to be based on true events. This turned out to be a half-truth: The real life events simply had not happened yet.

One scene in The Narrative of Arthur Gordon Pym of Nantucket visits a whaling ship lost at sea, taking with it all but four crewmen. Out of food, the men drew lots to see who would be eaten, the unfortunate decision landing on a young cabin boy named Richard Parker.

Forty-six years later, there was an actual disaster at sea involving the Mignonette. It became famous due to the legal consequences of some gruesome events on board, specifically the way the men drew lots and decided to eat their cabin boy...

Where it Gets Even Weirder:

The bizarre story was discovered decades later by 'Nigel Parker', a distant cousin of the Richard Parker who got eaten. You can only imagine what the fuck went through his mind when he stumbled upon the connection. And that would go down as the freakiest unintentional prediction of future events in a work of fiction, if it were not completely blown away by the below incident.

Morgan Robertson Writes About the Titanic 14 Years Early

James Cameron made it to Oscars with an incident which took place about hundred years ago. American author Morgan Robertson wrote a shitty book called "Futility, or the Wreck of the Titan", about the sinking of an "unskinkable" ocean liner. When you see the cover, you figure you're pretty clearly looking at a fictionalized version of the Titanic story. No surprise there. It's a story that's been told over and over (there were 13 Titanic movies before Cameron's, including one by the Nazis) but Robertson's book was first.

Where it Gets Weird:

He was so eager to be first, apparently, that he didn't bother to wait for the Titanic to actually sink before writing about it. The Wreck of the Titan was published in 1898, 14 years before Titanic was even finished.

The similarities between Robertson's work and the Titanic disaster are so astounding that one has to imagine if White Star Line built Titanic to Robertson's specs as a dare. The Titan was described as "the largest craft a float and the greatest of the works of men", "equal to that of a first class hotel" and, of course, "unsinkable".

Both ships were British-owned steel vessels, both around 800 feet long and sank after hitting an iceberg in the North Atlantic, in April, "around midnight." Sound like enough to keep you up at night? Maybe that's why Robertson republished the book in 1912 just in case enough people didn't know that he wrote it.

Where it Gets Even Weirder:

While the novel does bear some curious coincidences with the Titanic disaster, there are quite a few things that Robertson got flat wrong. For one, the Titanic did not crash into an iceberg "400 miles from Newfoundland" at 25 knots. It crashed into an iceberg 400 miles from Newfoundland at 22.5 knots.
Wait, what the fuck? That's one hell of a lucky guess!

But maybe the weirdest thing about Titan were points that had nothing to do with the story, For one, both the Titan and the Titanic had too few lifeboats to accommodate every passenger on board; the Titan carrying "as few as the law allowed." While Robertson decided to be generous and include four lifeboats more on his ship than Titanic, it's an odd point to bring up when you consider that lifeboats had nothing to do with the story. When Titan hit the iceberg, the ship sank immediately, making the point made about "lifeboats inconsequential".

Using LINQ to SQL Template - Part Two

2010-03-12T02:04:00.000-08:00

This post has reference to part one of this Article.

Create a new Class with the name "MyLinq". We are going to use the DataContextFactory Class which we created in Part One. Also assume in our database we have Table with name "User" and with the following Definition.

Also inside the "Linq to Sql" Template, the name of the "User" Table interface is "UserEntity". Now lets see how we can INSERT or UPDATE Data Rows in the User Table. Use the following block of code within MyLinq class,

public void InsertOrUpdateUserProfile(string userName, string phoneNumber)

{
using (DataDataContext db = DataContextFactory.CreateContext())

       {
            InsertUpdateUser(db, userName, phoneNumber);
            db.SubmitChanges();
        }
    }

    private void InsertUpdateUser(DataDataContext db, string userName, string phonenumber)
    {
        try
        {
            var userentity = (from entity in db.UserEntities
                              where entity.UserName == userName
                              select entity)

            List<UserEntity> uE = userentity.ToList();

            if (uE.Count == 0)
            {
                UserEntity userE = new UserEntity();
                userE.UserName = userName;
                userE.PhoneNumber = phonenumber;
                db.UserEntities.InsertOnSubmit(userE);
            }
            else
            {

// Not more than one element is considered

                UserEntity userE = userentity.Single();
                userE.PhoneNumber = phonenumber;
            }
        }
        catch(Exception)
        {
            throw new Exception("Unable to Insert or Update the Database");
        }
    }

Now use the below Two methods to DELETE option,

    public void DeleteUserProfile(string userName)
    {
        using (DataDataContext db = DataContextFactory.CreateContext())
        {
            DeleteUser(db, userName);
            db.SubmitChanges();
        }
    }

    private void DeleteUser(DataDataContext db, string userName)
    {
        try
        {
            db.UserEntities.DeleteAllOnSubmit(from entity in db.UserEntities
                                       where entity.UserName == userName
                                       select entity);
        }
        catch (Exception)
        {
            throw new Exception("Unable to Delete");
        }
    }
