Gmail Hack

I used to create two different accounts in a website for example Facebook but I asks me for a new email address or phone number. Which in turn has forced me to create a new Gmail ( I basically use Gmail than any other ) account. Creating a lot of Gmail accounts had become a problem as i can’t remember all the fancy name that I have used for the other ( fake – i mean just to create another user name ). But with a simple hack everything came to an end.

Gmail actually does not care if you add . (dot/full stop) to the email address.

For example my email id is “dhanvicse@gmail.com” and the Gmail sends all the mail that are meant for “dhanvi.cse@gmail.com” or “d.h.a.n.v.i.c.s.e@gmail.com”.(Note : gmail doesn’t allow a new user to choose the email id as “dhanvi.cse@gmail.com” it gives out the error that the email id is already taken )

Hence you have an infinite number of email id

dhanvicse@gmail.com
dhanvi.cse@gmail.com
d.h.a.n.v.i.c.s.e@gmail.com
dhanvicse……………………….@gmail.com
dhanvicse………………………………………………………………..@gmail.com

(Considering that i have already registered in a website with the email id “dhanvicse@gmail.com”)

Where you try to create another account in other websites with the email id “dhanvi.cse@gmail.com”. The other websites (for example facebook) checks in it database weather “dhanvi.cse@gmail.com” is there or not . The answer is no because it has only “dhanvicse@gmail.com” . The other websites (facebook) thinks that you are new user and it gives the new user name in the website .But all the emails are directed to your same email id “dhanvicse@gmail.com”. As Gmail know that “dhanvi.cse@gmail.com” == “dhanvicse@gmail.com”. So you can create any number of accounts in other website by using the same gmail.

Finally there is a small thing to say we have not just infinite but infinite multiplied by 2:

Because the gmail is same as googlemail . I mean that you got an exemption in the extension

dhanvicse@gmail.com == dhanvicse@googlemail.com

and all this case comes true for all the ones mentioned above I mean

dhanvi.cse@gmail.com == dhanvi.cse@googlemail.com == dhanvicse@gmail.com == dhanvicse@googlemail.com and so on ……………………………

Note : This trick is not useful if the other website have a special option of sign up by using Gmail or google + 🙁 And you can use this trick to login to google websites such as drive 🙂 lol if you tried that google can find it . That why i mentioned other websites which means that it is not a google product and it is not connected to google in any manner.

Browser shortcuts

The most thing that we use the most used application in our daily uses Remembering some shortcuts help us to increase the our browsing speed. You need not by heart them, but by regular use you become used to them. And then you will customizing the shortcuts in your browser. The browsers generally used these day’s are Google’s Chrome and Mozilla’s Firefox . Fortunately both of them have almost same shortcuts and any almost any modern browser have the same shortcut’s. 🙂

Every second that you spend on trying to learn the shortcuts is worth because it saves a lot of time in the future when compared to the little time you spent on learning or practicing. In this blog I have given a list of shortcuts which every one uses a lot.

The first and foremost thing that we do in a browser is that to open a new tab to surf the new page. It can be done by Ctrl along with t ie Ctrl + T

Ctrl + T New tab.

Once we open a new tab what is the thing that we do the most is closing the tab. This can be done by Ctrl + W

Ctrl + W Close the present tab

If you are having only one tab and if you use this shortcut then the window will be closed. This can be done at any time having any number of tabs by using this shortcut.

Ctrl + Q Quit the window (This does not work for chrome but for most of the browsers )

Till now what you have seen is that only how to open and close a tab in the browser. But the things that we do is usually is shift between the tabs.

This can be done by done by pressing two keys at a time that is

Ctrl + Tab ( By pressing the two keys at a time we move across in the clock wise manner )
Ctrl + Shift + Tab (This is same as above but it moves across in ante clock wise manner)

The above shortcut is a does not come in handy if you are have a lot of tabs then you feel to catch the mouse again 🙂 leaving behind all the shortcuts, but there is a solution for this type of scenario where you have many tabs and opened in the browser (which is a habit of mine 🙂 )

Alt + 1 ( Wherever you are in the browser it take you to the first tab of the browser .In my case it will be usually Gmail )
Alt + 2………..8 (Same as above it goes to the corresponding tab number )
Alt +9 (Takes us to the last tab of the browser)

This shortcuts helps you mainly to go to the first and last tabs of the browser easily but if you are good at math you can give a try from 2 to 8 numbers and the corresponding tabs 🙂

NOTE: The about shortcut works also with Ctrl in Chrome Browser. But prefer the Alt button because it might not work sometimes when it clashes with other shortcuts.

And one more shortcut which we do is refreshing the page ( ie.. reload the page).This is the simplest shortcut ever.

F5 (ie .. the fifth functional key).

Incase you don’t like to move your hands to the top of the keyboard then you could try this shortcut.

Ctrl + R (reload the page )

And we always press the X option at the address bar if the page is loading for too much time the shortcut is

Esc ( The shortcut is nothing other than the escape button itself, the loading of the page can be stopped by just pressing the escape key )

We always have to do something with the url ( for exam send to the link as a message to your friend or change it a bit to go to another page ) so we need to go to the address bar in the browser. This can be done by

F6 ( by just pressing the f6 functional key your cursor selects the whole address bar )
Ctrl + L ( this is the alternative shortcut of the f6)

And one more habit we have while browsing is that we go to the previous webpage very often this is the same with the going to the next page after going back, for this purpose we use the little arrows at the top beside the address bar, but this can be done by using a small shortcut

Alt + (
Alt + ( ——–> right arrow ) by pressing these two buttons at a time we can go to the next page

In the case of professionals who need to find the exact word this shortcut may come into handy

Ctrl + F ( this is same as the find option).

The main objective of the shortcuts is to save time from moving the hands from the key board and grab the mouse.

Once you get used to the shortcuts you can go ahead to the settings and create you own shortcuts and use them ahead.

Some of the other shortcuts which i have known are mentioned below in case if you feel that the above shortcuts does not satisfy your needs.

Alt + D bookmark the current page
Alt + H show history for chrome
Ctrl + Alt + H history for Firefox.
Alt + J show the downloads (only for chrome)
Ctrl + Shift + Y downloads in case of Firefox.

Getting started with TopCoder

Hi Friends

This post is perfectly technical blog post .

And this is for the persons who are interested in programming, topcoder is a website which is a very good website for learning programming and here is the pic of the website

And coming to the programming part, topcoder contains many parts and we need to do in order to improve your programming is algorithms , this can be selected at http://community.topcoder.com/tc ,which looks like this.

And then select Register Now in the top right corner if you are not registered to topcoder.

Then you will get a page like this

Note : Select all the options in the above page other wise you have to face problems in the upcoming of topcoder. Then you would get a page like this :

Give all the personal info and get a handle in topcoder (nothing but user name ) login to your account by entering the handle and password of the topcoder.

Now you are done with login issues. Now coming to the coding part select a symbol like this on top left part of the page, next to the the home symbol

Then you will be asked to save the file save the copy and keep it in a folder named as topcoder for further use so that you need not do this again. Now double click you will get a topcoder arenia like this.

Then enter the handle (user name ) and password , u will get like this

Now coming to the problem solving we will go with srm’s (Single Round Matches) , you can solve the live srm’s after trying the old ones. That is we will be doing it in practice rooms one can do all of them but srm’s are good. And if you are a beginner div 2 are easy ones , I strongly prefer you to do the div 2 first .Even in div 2 there are different levels like (250,500,1000) first solve the 250 . And now we go to the the most important part “Editor” (KawigiEdit) The java plugin can be downloaded from here http://topcoder.yajags.com/KawigiEdit_2.1.jar or you can get the latest one from here http://topcoder.yajags.com/ and from the documentation from here http://topcoder.yajags.com/KawigiEdit.html

And the instructions they give will be like this

These are the exact pictures below .In “options” select the “editor preferences”

select add we get like this

Name can be what ever you want but entry point should be “kawigi.KawigiEdit” better copy this and paste it .Then you would have a editor(kawigi) in the editor preferences make it as default and save it ie..

Now you can go ahead and solve the sums I prefer you to do in this order http://community.topcoder.com/tc?module=ProblemArchive&sc=7&sd=desc as this is easy one in the starting select one sum and open it in topcoder arena for example CheckFunction

And the sum will be like this

I like to work like this

this can be done by clicking the

on top right corner

And after writing the code you can can compile it by saving it and then compiling

then select run tests

If get the option you are a stud then go ahead and submit it…..you can try live srm’s after solving few of the previous srm’s

All the best, happy topcoding ……..
