How to check if an email is valid
|
Learn how to check if an email address is valid and really exists without sending a test mail to that address. Works for Gmail, Outlook and Yahoo addresses.
How do you know if an email address exists or not? The easy option would be that you send a dummy mail to that email address, wait for an hour or so and if your message bounces, it is very likely that the particular email address does not exist. The approach works but wouldn’t it be nice if you could check any email address instantly without even sending that test message?
The other slightly technical option to verify an email address is by querying the mail server. You connect to the mail server through telnet (see video), enter your email address and the other email address that you are trying to verify. If the server response is an error code, the email address is probably not valid.
How to Check Email Addresses Instantly
Let me share an extremely simple method for checking if an email address is valid and exists or not.
Go to the login page of the email service and pretend that you no longer remember the password of your email account. The service will ask for your email address where they can send the password recovery instructions. Here if you enter an email address that does exist, the service is mostly likely to tell you that the particular user name does not exist. I have tested this with Google Apps, Yahoo Mail and Outlook (Hotmail) and the method works with them all.
For Gmail and Google Apps Accounts
Go to Google’s password assistance page at google.com/accounts/recovery and choose the I don’t know my password option. Enter the email address that you are trying to verify – it could be an @gmail address or a Google Apps address – and choose Continue. If that address is not valid, Google will throw an error saying No account found with that email address.
Alternatively, you can go to the Gmail Sign-up page at accounts.google.com/SignUp and try creating a new Gmail account with the address that you are trying to verify. For valid email address, the error would say Someone already has that username.
For Outlook, Hotmail and Live.com Addresses
Go to account.live.com/ResetPassword, choose the I forgot my password option and enter the Outlook email address. You will get an error saying The Microsoft account is incorrect. for addresses that do not exist.
For Verifying Yahoo Email Addresses
Go to Yahoo’s account recovery page at edit.yahoo.com/forgot, enter the @yahoo.com email address that you are checking for validity and click the Next button. Yahoo will say We couldn’t match the Yahoo ID you entered with information in our database if the email address does not exist.

Hacking for what?
I know I'll be cursed for this but sometimes I think about hacking and I came to only one conclusion: Hackers hack because they want to show how cool and smart they are.
If you ask yourself why you hack? Or why hackers hack? You will commonly have two answers:
1) Because they want to steal money (or goods).
2) Because they want to prove to some company that they have security issues.
Right?
Ok, let's take a look to those both reasons:
1) No matter how smart, how genius you are, 9 out of 10 hackers go to jail. Yeah, I know, then they commonly are asked for their services (Well, not that commonly). Maybe in the past but know with all the communication we have, I'm sure companies can hire a decent person as smart as a hacker)
So, my question is: If you are so intelligent, why going to jail? Is that time in jail worth a possible future good job? No way... If you say "yes", you don't actually know how is to be in jail...
2) Bullshit. What you want to show is how cool and smart you are. So stop doing it. You know what you get? You get a heavier and heavier software (just like MS Windows) because they have to stop assholes like these hackers who think they're doing something good for humanity.
If you take advantage of any security hole and steal money, I'm sure you will be jailed (because of my point #1 here)
I like the act of hacking because it makes me a better software developer but that's it. Knowing how a hacker thinks, I can get a faster and a more solid product. But I don't think I can make a 100% secure app. Becuase that should not matter.
Sorry folks but today I'm in a bad mood with hackers :-|

Matter - Javascript Physics
Matter.js
The Matter.js Wrecking Ball demo.
Matter.js (GitHub: liabru / matter-js, License: MIT) by Liam Brummitt is a stable and flexible rigid body physics engine for browsers. The author describes it as an alpha project that came about as a result of learning game programming.
If you’re interested in reading more about physics for game programming, Liam has collected some useful resources in Game physics for beginners.
Matter.js uses time-corrected Verlet integration, adaptive grid broad-phase detection, AABB mid-phase detection, SAT narrow-phase detection, and other algorithms for managing collisions and physical simulation. More well-known engines like Box2D support these features, but if you take a look at the some of the classes Liam has written then you’ll see how clean and readable his version is.
I’ve been looking at the source to see how to use it, and the API seems friendly to me:
var Bodies = Matter.Bodies;
var Engine = Matter.Engine;
var engine = Engine.create(container, options);
var World = Matter.World;
World.addBody(engine.world, Bodies.rectangle(300, 180, 700, 20, { isStatic: true, angle: Math.PI * 0.06 }));
World.addBody(enigne.world, Bodies.rectangle(300, 70, 40, 40, { friction: 0.001 }));
The demo is cool, so try it out if you want to experiment!

Nokia X Hacked to run Google products
Original post: http://forum.xda-developers.com/showthread.php?t=2665401
GUIDE
This is a rudimental way to do it. This happen because we dont have recovery yet. Bootloader seems locked in some ways, so instead
flashing a single zip, we need this way to get it working.
1) You should need a rooted device. Use Gandalf Exploit included in Framaroot app.
(Download it from http://forum.xda-developers.com/atta...1&d=1391850491)
2) We need a Root explorer app, use whatever you want. (For example: https://play.google.com/store/apps/d...explorer&hl=es)
3) Extract and copy all apks from "NokiaX_Gapps_KashaMalaga_28.02.2014.zip" to /system/app and change permisions for this files.

4) Reboot
5) Extract and install as normal user every single needed apk include in "NokiaX_SomeGoogleApps.zip". (If wanna use Google Now Launcher, open it after install it)
6) Try to launch Play Store, its gonna ask u for a Google Account et voilà
