Facebook User Authentication: Get access to user data

This is the extension of my previous article on facebook share. But, no need of prior knowledge. Proceed from here.

After registering a developer account @ https://developers.facebook.com/ , create an app.
Note the App-Id and don't forget to add the redirect url under the app settings section.
Also add all the access permissions you would like to get from the user under Auth Dalog section.

All these permissions are to be used later to retrieve corresponding data.

URL pattern to implement the authentication is as follows:

http://m.facebook.com/dialog/oauth?client_id=<APP-ID>
&redirect_uri=<PATH- TO-TARGETTED-LOCATION>
&scope=<ALL-THE-PERMISSIONS-LIKE-email,offline_access>
&response_type=token

Just modify the CAPITAL lettered data, and for the redirect-url no need of using quotation marks("")

Java: Use BigInteger in for-loop

In my previous post , I mentioned a way to handle large integers by using BigInteger. Now I'm going to provide a very important usage of it. We often use for-loop. So here is the way to use it: Ordinary integers: for(int i = 1; i <= n; i++) {  //Task to do } BigInteger: for (BigInteger bi = BigInteger.valueOf(1);                 bi.compareTo(n) <= 0;                 bi = bi.add(BigInteger.ONE)) { //Task to do } here n is a BigInteger variable.

OS X 10.8 Mountain Lion bootable USB (without MAC)

Download the raw file from here . How to use: 1 - Copy the .raw file to an USB stick using  SUSE Studio Image Writer . If you have error during copy, eject and re-connect the pen drive. When Windows asks if you want to format it, cancel and run Image Writer again. If the problem persists, disable your anti-virus software, it may be blocking raw write to the drive. Another Image Writer for Windows, if SUSE doesn't work https://launchpad.net/win32-image-writer/+download 2 - Boot the USB drive and install. If you need, type  boot options , for example: -v (verbose boot) [default] -x (safe) -s (single user) GraphicsEnabler=yes (enable graphics card drivers) [default] USBBusFix=yes (fix problems with USB devices) npci=0x2000 (use if boot stops at "PCI configuration begin") cpus=1 If you need, use  TransMac  to remove kexts which are causing problems (System/Library/Extensions) and use the flag -f (ignore caches) at boot, or remove /System/Libra...
