Upgrading your PHP version

There are two ways to do this. I'll list out both in this post.

1. Backing Up and upgrading

Take a backup of your htdocs and data folder (subfolder of mysql folder), reinstall upgrade version and replace those folders.

2. Overwriting the new version

Inspired by YAIG(Yet Another IT Guy)'s blog, Here is the how-to version

Warning: Do this at your own risk

Download the latest version of PHP (zip package not the installer)
De-archive it to a directory
Copy the contents of the directory in the PHP sub-folder of your XAMPP installation directory, overwriting the files which are already present
Now a simple trick: take the files which have a _2 in their names (for example php5apache2_2.dll), copy them in the apache\bin subdirectory and remove the _2 part, overwriting the existing files.

Scan Conversion(Circle) - Midpoint Algorithm

Assignment 05. Use the mid-point circle technique to derive the necessary equations to scan convert the following circular sector (i.e., points from 27 0 o to 315 o ) . Implement your method and u se the circle's symmetric property to draw complete circles. The file is available here ( ScanConvertCirclemidpoint.cpp ) Play with it. You will understand..

Raising cryptography’s standards

Calculating encryption schemes’ theoretical security guarantees eases comparison, improvement. Most modern cryptographic schemes rely on computational complexity for their security. In principle, they can be cracked, but that would take a prohibitively long time, even with enormous computational resources. There is, however, another notion of security — information-theoretic security — which means that even an adversary with unbounded computational power could extract no useful information from an encrypted message. Cryptographic schemes that promise information-theoretical security have been devised, but they’re far too complicated to be practical. In a series of papers presented at the Allerton Conference on Communication, Control, and Computing, researchers at MIT and Maynooth University in Ireland have shown that existing, practical cryptographic schemes come with their own information-theoretic guarantees: Some of the data they encode can’t be extracted, even by a ...

TrashCoders

As I'm forming a Club "TrashCoders" after our Summer Holidays (May 2nd week), and going to share the knowledge I have, I created a new blog to upload all of the works we do in the Club. Hope you guys have some ideas and/or tips. Trash Coders Happy Holidays..
