How To Get Back Deleted Whatsapp Messages/Data ?

We All are Aware of Messaging app Called Whatsapp. We Use it daily and no doubt We Love it, but have you been in a Situation when you accidently delete an important message on Whatsapp and you don’t know what to do next? 

Well, Touchscreen devices are great, but can also be frustrating. A simple tap on the wrong option, for example, and your Whatsapp chat history is gone.

 Take another one, Suppose you meant to hit Add a conversation shortcut, but instead you tapped Delete chat. Then you clicked “Yes” without thinking! Your chats are gone now leaving you without a record. 



How do you get them back? Alright! There are two methods to do this:

1. Manually
2. Using Web Application

MANUALLY:

This method works because Whatsapp Creates backup of all the data each day at 4 am (system time) which is Stored in the SD card of your Android Smartphone. To get deleted Whatsapp messages just follow below simple steps:

 STEP 1:  First of all Navigate to the Whatsapp database folder, the path is: File Explorer > sdcard/Whatsapp/Databases.

 STEP 2:  In the Database folder you will see Chat files which are with names similar like msgstore-2014-01-04.1.db.crypt. You may notices the file names have dates as well but, there is a File which is msgstore.db.crypt, we need to rename it, you can add any word before msgstore.db.crypt or, rename it to “OLD”.

 STEP 3: After renaming that files, now select the file which shows appropriate date before you accidently deleted your Whatsapp messages, and then rename that file to msgstore.db.crypt. This Renaming process can also be done on your PC by connecting your device.

STEP 4: Go to Setting > Applications > manage applications> Whatsapp and Click on Clear Data. Now open Whatsapp, Choose Restore when it prompts. That’s it, the chat file saved as msgstore.db.crypt will be restored and hence your messages too.

STEP 5: Click on Restore instead of No Thanks.

Note: In Case if you have deleted any Image, Audio or Video from your Whatsapp chat, then don’t worry, it’s not deleted forever until you delete it. To view that image or Video all you have to do is with the help of your Preferred file Manager, Navigate to sdcard/Whatsapp/Media Where you will find folders with names Whatsapp Audio, Whatsapp images, Whatsapp video, Open them up to find the file you are looking for.

USING WEB-APPLICATION:

There is a great Web Application Called Recover Messages which is Specially Designed to Get back Deleted Whatsapp Messages. 

This is a Free Online Services which will help you to Read the Content of the database file and shows you Sent and Received messages.

Simply Go to Recover messages Site, Click on Select SQlite file to upload the Database file, Select the Database file from SD card, Check the box which says I accept the terms of use and click on Scan.

Just wait for few seconds while it takes a bit of time to show you the Messages. This will take few minutes to show your deleted messages. 

 Note: The only drawback is you can only extract and View/Read your deleted messages but you cannot restore them to your Whatsapp chat history.

How do Websites like Facebook store Your password: An easy Explanation.


After making some websites I came to know a very interesting fact about which I was always clueless.

Password protected web sites do not need to store your actual password, Facebook indeed did not. For the nontechnical part of the audience, let me try to explain how this actually works.

A well designed password system uses something called a "hash function." (Hash as in hash browns, not hashish. )

Think of a hash function as a machine. It has a hopper on the top and you throw in the password, and a moment later, something completely incomprehensible called a "hash" is spit out.

For example, if you feed into the machine "p4ssw0rd", it might spit out "2a9d119d". 

Now what on earth is the point of a machine that takes a perfectly good password and spits out a bunch of garbled nonsense?

The trick is that, given the same password, it will always spit out the same garbled nonsense. If you feed in "p4ssw0rd" it always spits out "2a9d119d". If you feed in "qwerty" it always spits out "d8578edf".

And the hashing machine gets more amazing. When you give it different inputs, you are almost guaranteed to get different outputs. (The mathematicians among you may notice that for this to be true, the output should probably be longer than the input. Indeed it usually is.)

Now when somebody sets up a password, you don't just store that password on disk. You first feed it through the machine, and you store the hash. For instance, if somebody sets up "p4ssw0rd" as their password, you would store "2a9d119d".

Now when that person wants to log in, they type in "p4ssw0rd", and we need to see if that is the correct password. So we feed it through the same machine, and because the machine always spits out the same output if you give it the same input, it's going to again give us "2a9d11d". That matches the hash stored on disk so it will let the person in.

But suppose that you have forgotten the password and you call a system administrator and ask for them to look up the password in the system. You're out of luck! The only thing stored in the system is "2a9d11d", which by itself is completely useless to you.

What you would need is an unhashing machine, that takes in "2a9d11d" and gives you back "p4ssw0rd". But one of the amazing features of a good hashing machine is that it is extremely hard to build such an unhashing machine. Basically, the only way to do it is to simply feed all possible passwords into the hashing machine until "2a9d11d" comes out. But there are a lot of possible passwords, and that would take a long time.

Now where do we get this amazing hashing machine, that always produces the same output for the same input, virtually always produces different outputs for different inputs, and for which it is practically impossible to build an unhashing machine?

This is where a branch of math called cryptography comes in. Cryptography is a highly specialized branch of math that deals with creating exotic contraptions like hash functions and ciphers. Every once in a while, the cryptographers discover that for some hash function it actually isn't that hard to build the unhashing machine after all, and everybody has to scurry around and switch to using a different hash function. But by and large, it all works, even though the majority of mathematicians and computer scientists who don't specialize in cryptography don't really know how it works.

We have come to the end of my explanation of how Facebook, as well as any other decently implemented computer system, can know whether you typed the correct password on any given occasion without actually storing your password. Reality is a bit more complicated. (It always is...) There is something called password salting, for instance, that makes it a bit harder to crack passwords even if you use a common dictionary word for your password (which you should nevertheless never do). You can go read about it on Wikipedia, or in a good computer security book.

Resources to help you: 

Wikipedia has an extensive, if somewhat rambling, overview of Password security; 
also, an excellent list of common cryptographic hash algorithms and their known vulnerabilities: 
and articles about techniques such as Key stretching (where you use multiple hashes in series to increase the difficulty of reversing the hash) and Salt (which prevents the use of precomputed tables of hashes of common passwords by "hashing in" some additional information known as the "salt").

Note that all good computer security is based on multiple lines of defense; in the case of passwords, you typically want to try very hard to prevent even the hashed passwords from escaping in the first place, and rate-limit login attempts.

How to automatically shutdown your windows system after a specific time?



Jesus Christ!! I have never known that it would be so easy. But now I am sharing it with you. It means it is so easy since I don't do hard. Remember??

Okay!! So, It's just one line command. Now follow my steps:

STEP 1: open run command by pressing "start+r" or just search for "run" in start menu.

STEP 2: Type shutdown -s -f -t 3600  and click ok.




Now, 3600 is number of seconds i.e. 1 hour in this case.

After 3600 seconds your system terminates all programs and automatically shuts down without prompting.

This is very useful If you're going out for more than 3-4 hrs and you want to copy a large file, process a HD video, installing a heavy game etc. which would take, assume 3-4 hours to complete and there's no one to shut it down manually after the work is done. 

When you have done with all steps, you will see a notification box like shown below.



(Don't worry about data being lost, just set few minutes more than ETA and everything will be fine).

Ohh!! I missed. You can set any number of seconds as much as you want for whole days or for whole life. 

If you find difficult to find number of seconds in 'n' hours, just type "calc" in run window which opens a calculator, you use it to find out multiples of 3600, ex: 7*3600 for 7hrs which is 25200, so "shutdown -s -f -t 25200" for 7hrs.

Note:  If you want to cancel the scheduled shut down, type "shutdown -a" in run window. 

That's it for today. Now, take a Nap.

How To Make your Computer Talk ?? Serious Experiment.

Indeed. You can also make your computer speak whatever you input to it.
Wait!! NO its Okay!!!

To create one such talk script, follow the steps given below:-

Steps 1: Open Notepad.
Step 2: Copy and paste the exact code given below.

          Dim Message, Speak
          Message=InputBox("Enter text for Abhishek Raj","Speak")
          Set Speak=CreateObject("sapi.spvoice")
          Speak.Speak Message

Step 3. Click on File Menu, Save As, select All Types in Save as Type option, and save the file as Speak.vbs.

Note 1: Remember you can use anyname instead of Speak but ".vbs" is necessary.

Step 4.  Double click on the saved file, a window will open like the one in the image. Enter some text in enter text column and click OK.



Now your Computer will speak / talk whatever you would type in Step 4.

Warning: Please go to sleep after performing this experiment. Otherwise you will get headache. :P

13 Qualities that Every Introverts and Emotionally Strong People Possess


You know that there is a particular aspect of mental strength that decides whether or not you will have a good life. The particular area of mental strength that has the greatest impact is that of emotional strength and its play a greatest role in introvert's and ambivert's life.

Emotions are our greatest motivators. Unfortunately, they can motivate us to act in any direction, even the wrong one. For this is reason, emotional strength is essential. There are countless situations that emotionally strong people (generally they in introvert categories) avoid and many actions they never take.

1. THEY DON'T BEG FOR ATTENTION

Needing attention is directly linked to emotion. Those who feel the need for recognition only find themselves experiencing feeling of worth when others make them feel needed; it's as if these people are uncertain of their value, or if they have any ounce of self- worth.

2. THEY DON'T ALLOW OTHER TO BRING THEM DOWN

Emotional strength requires flexibility. This world is filled with haters and trolls. There is jealous eyes lurking around every corner. The unfortunate truth is that often the people who hold us back the most are those closest to us. Getting rid of these people is often the best solution, but also the most difficult.

3.  THEY DON'T HOLD GRUDGES

If you're holding a grudge, then you already care more about a situation than you should. If person apologizes genuinely, forgive him or her. If this person doesn't apologize, then don't interact with him or her, but don't hold grudges because its do more harm than good.

4.  THEY NEVER STOP DOING THEIR OWN THING

Introverts or emotionally strong people do what they do because they love doing it. They don't plan on slowing down or stopping for anyone who seems their happiness inappropriate.

5. THEY NEVER STOP BELIEVING IN THEMSELVES

Those who love themselves and understand themselves and those who aren't afraid or proud to be themselves never doubt themselves.

6. THEY DON'T ACT LIKE BITCHES OR A*SH*LES

People are mean. But we wonder, why? Being a jerk is only good as an intimidation factor, and if you are trying to intimidate people, then you negotiator by profession; if you're intimidating just for the sake of it, you're obviously overcompensating for lack of confidence.

7. THEY'RE NOT AFRAID OF SLOWING DOWN

Introverts aren't in need of constant action and excitement. They don't need to run around all day and keep moving in order to avoid their demons. They appreciate a slow moment because it brings them closer to what it feels like to do nothing but living, breathing. This is not to say that they don't enjoy excitement in their lives, but they aren't junkies and are more than happy to just go for a walk and smell the roses.

8. THEY DON'T DO THINGS THEY DON'T WANT TO DO

We all do things that we don't love to do, but we should never do things that we don't want to do. Introverts and Emotionally strong understand that and almost always manage to figure out a way to focus on what they love, which allow them to figure out what they need to do, in order to do what they love, Although they may not love every second of it, they like doing what they are doing because it's bringing them one step closer to what they would love to do.

9. THEY HAVE NO PROBLEM SAYING "NO"

If you can't say "no" you will get abused. You will be consider a pushover and no one will ever ask you for your opinion or take it seriously when you give it. Saying "NO" reminds people that they don't have control over you.

10. THEY DON'T "FORGET" TO GIVE BACK

We're not too busy or too poor to donate our money or time. We don't forget, either. Some people just choose to ignore our responsibilities as human beings.  The stronger you are emotionally, the more you come to appreciate others and life itself.

11. THEY DON'T FEEL THE NEED TO FIT IN

The stronger you are emotionally, the more independent you become. You don't feel the need to fit in because you fit in where it matters: THE WORLD. People form smaller social groups that are often skewed and unhealthy.

12. THEY DON'T FORGET THAT HAPPINESS IS A DECISION

Introverts have learned to understand the power their brains have over both the mind and body. They understand that emotions are reactions. In other words, our emotion don't reflect reality, rather, our emotions reflect the way we interpret reality.

13. THEY AREN'T AFRAID TO "LOVE"

Most Importantly, If you're afraid to love, you don't have enough confidence in yourself. You obviously think you can't be in a lasting relationship, but only in one that is doomed for disaster. You don't want to get hurt again because getting hurt really sucks. There is no reason for you to get your heart broken again because you are awesome. If things don't work out, it's not you. It's the two of you together. Unless, of course, you are an awful human being; in that case. it is YOU.

How To Add The Recycle Bin To The Taskbar In Windows 7

When you’re busy multi-tasking on your PC, sometimes getting to the Recycle Bin can a pain. So let’s take a look at a couple of different methods for adding the Recycle Bin to your Taskbar for easier access.


STEP 1: The first thing you want to do is create a new shortcut on the desktop.


STEP 2: Now for the location type in or copy and paste the following:
explorer.exe shell:RecycleBinFolder
It should look like this…then click the Next button.


STEP 4: Now name it Recycle Bin or whatever you wish to call it and click Finish.

STEP 5: Now we need to change the icon to the look of the Recycle Bin so right-click the icon and go to Properties. Click on the Change Icon button.

STEP 6: Type or copy and paste the following into the field for where to look for icons and hit Enter.
%SystemRoot%\system32\imageres.dll


In the new window of icons just scroll over a bit and find the Recycle Bin select it and click Ok. Click on Apply and Ok to close out of the Recycle Bin Properties screen.

STEP 7: you’ll now have your new Recycle Bin shortcut. You can both drag it to your Taskbar or right-click and select Pin to Taskbar.

There you go! Now you have the Recycle Bin on the Taskbar, and if you want to remove it just unpin it.
This gives you another way to quickly access the Recycle Bin while you are busy multi-tasking. Also, you will probably want to remove the shortcut you made on the desktop. With this method you can’t drag items directly to the icon on the Taskbar, but it let’s you open up the bin.
