Do not do immediately after meals

There are many things which we do in our daily life, which may lead to some medical or physical issues which can be avoided very easily if you know these small things.

Don't :-

• Eat fruits

When you eat your fruits with meals, the fruit is stuck in the stomach along with the contents of the meals and cannot reach the intestines in time. Lying there they get spoilt and spoil the remaining food in the stomach too. Thus it is recommended that you eat a fruit at least one hour after eating a meal or before your meal and preferably in the morning with empty stomach. It is in the morning that the body can best use the nutrients in the fruit and get enough energy to start the day.

• Drink Tea

Tea contains high amount of acid. It will cause the Protein content in the food so difficult to digest the food you ate. But you can drink after an hour.

• Loosen your belt 

Normally there is a temptation of loosening belt after a good meal. But we need to know that it causes the intestines to twist or block .
It may also cause you to feel comfortable and you may continue eating, which leads to over food in your stomach.

• Take Bath

This will cause increasing your blood flow to you body parts like hands, legs & body so amount of blood around the stomach will reduce.
So it will leads to delaying your digestion

• Walk

This can result to acid reflex and indigestion. But good to do do this after say half an hour after meals

• Sleep

The food will not be able to digest properly if you sleep immediately afer meals. so this will lead to gastric & infection in our intestines.

• Smoke

Smoking the cigarette immediately  after meal is comparable to smoking 10 cigarettes  so the chances of affecting cancer is much higher.

Kill Diabetics with curry leaf

Diabetes is a disease in which patience has high blood glucose or called as blood sugar,

• Make tea with  around 15 curry leaves in one cup of water and have many cups of tea daily as much as you can
• You can also make chutney with more number of curry leaves grind with ginger and garlic

Drink Water, Stay Healthy and Be Active

Just after waking up, drink water in empty stomach every morning.

Drink water immediately after waking up every morning. Also, many scientific tests have proved its value.

As per the various scientific study, it is good and effective for many diseases like

Headache, body related ache, heart, asthma, TB, meningitis, kidney and urine related diseases, arthritis, fast heart beat, epilepsy, excess fatness, vomiting, gastritis, diarrhea, piles, diabetes, constipation, all eye diseases, womb, cancer and menstrual disorders, ear nose and throat diseases.

All you have to do is

• As soon as get up from bed even before brushing teeth, drink atleast 4 glasses of water(160ml) 
• Those who are old and can't drink 4 glass of water, can start with 1 glass and gradually increase the level.
• After brushing tooth dont eat or drink anything for next 45 minute(after that everything normal)
• Don't eat anyting for 2 hours after breakfast, lunch and dinner.

As this method doesn't have any side effects(except you have to urinate few times extra than usual), good to give a try .

Enjoy a healthy and wealthy life.

Tips to increase mielage of you car

Think to remember while filling fuels in your car / bike

• Fuel at night or early morning: 

It is always  better to fill your car during early morning, when the ground temperature is still cold.
You know all service stations have their storage tanks underground.The colder the ground, the more dense the fuel. When it gets warmer, petrol expands.
So, when filling fuel in the afternoon or in the evening, your one liter is not exactly a liter.
In the petroleum terms, the specific gravity and the temperature play an important role. 1 degree rise in temperature is a big deal for this business. But dont think the service stations have temperature compensation at the pumps.

• Better to fill fuel when half tank empty: 

It is good fill the fuel when your tank is HALF FULL because, the more fuel you have in your tank the less is the air occupying its empty space. Petrol evaporates faster than you can imagine.

• Make sure Nozzle trigger in medium or low stage

You can find Nozzle trigger to fill the petrol  has three stages-Low, Medium, and High.
Make sure it not in  fast mode, while filling petrol. It should be in the low stage to minimise the impacts of vapour and to have maximum economy of petrol.. Filling petrol at the faster rate means you have more gas with your liquid petrol.

• Don't fill when petrol tankers unloading fuel

Because when the tankers fill fuel at the fuel station all the dirt that is settled at the bottom down gets disturbed and if you are fueling at the same time it can get into your vehicle tank along with fuel - it can badly affect your engine.

• Proper tyre pressure

Tyre pressure must be checked once every two weeks. It helps to reduce the drag while driving thus increasing your mileage.

• Avoid Unwanted weight in car

Every extra kilo of weight will need additional fuel, decreasing the mileage.

To run the tomcat, which you installed(not the embedded one- and you need to run the manager portal of tomcat for auto deploy from maven

In eclipse ->

 Tomcat v7.0 Server at localhost.server  - take properties ->and click "switch location"

open it -> “server location” select “use Tomcat Installation(takes control of tomcat installation” 

now right click your spring project and run as “maven build “ -> tomcat7:redeploy will do the magic

Enable or disable hidden folders in MAC OS X

Enable or disable hidden folders in MAC OS X

• For Enable/show

Open a Terminal 

Execute this command 


defaults write com.apple.finder AppleShowAllFiles -bool true

• And to hide/disable

Execute this in the terminal


defaults write com.apple.finder AppleShowAllFiles -bool false

And if it didn't take effect, try logout and login

But if you are not comfortable with Terminals, many apps are available , which helps to do this from UI itself 
ex: invisiblix

Overriding rules in Java

• Should be same method name and argument list in base class and derived class
• Return type can be co-variant, meaning if super class return type is Map, subclass return type can be Hash Map.
• Access specifier in the derived class should be broader/bigger than that in the base class;
• ie; if base class method is protected, the derived class method can  be protected or public- but cannot be private or default
• Exception in the subclass  should be same or subclass of base class
• ie:-if base class exception is IOException, subclass can be FilenotFoundException-but cannot be Exception.

Get the source code from an APK

First Download

• dex2jar -> https://code.google.com/p/dex2jar/
• Java Decompiler –> http://java.decompiler.free.fr/?q=jdgui
• android-apktool and apktool- -> https://code.google.com/p/android-apktool/

For Source code

Rename the apk file to zip file. Extract the files in the same folder

Extract dex2jar into the same folder, or copy classes.dex from the extracted apk to the dex2jar extracted folder.

Give the command 

#dex2jar classes.dex

You can now see class_dex2jar in your folder( a executable jar file )

Now you run jd-gui.exe downloaded with the java decompiler.

Open the class_dex2jar folder  in decompiler(jd-gui), now you can see all source codes

File-> Save all sources

Now you have the java source in zip file named classes_dex2jar.src.

For XML

Create a new folder for xml, and put the apk file in that folder.

Now extract the downloaded apktool and apktool-install-window.

Put your xxx.apk in it then run the command 

     apktool if xxx.apk

after that run the command 

     apktool d xxx.apk

A new folder with the xml files will be created.

So All the source code is ready -- enjoy :)

Please Note: Do not misuse this tutorial, just sharing my knowledge for learning purpous

Aggregation

Aggregation means HAS –A relationship

Eg: Employee has Address

ie-

class Employee{

int id;

String name,salary;

Address address;//Address is a class

…

}

employee -> name, id, salary also has Address -> which itself has different attribute like pincode, city, country etc.

When there is no IS-A relationship(ie: inheritance), best way of code reuse is aggregation.

Inheritance should be used only if the –IS-A relationship is maintained in the life time of the object, otherwise aggregation is the best choice.
