Harvesting Email Addresses from a Website using Java

In this tutorial we’ll be creating a small java command line application to extract email addresses from websites, a program like this comes in handy for people who are into advertising and stuff.

So before we jump right into programming, lets think about the possible steps of the program.

Setting up your Raspberry PI 2 without External Display

This tutorial will guide you how to get your Raspberry PI 2 ready for action. Recently I bought a RPI for my project and I went through absolute shit storm trying to set it up correctly, so after searching google and doing hit n trial methods I was finally able to setup my RPI.

In this tutorial we will be using no external display i.e. HDMI with TV or monitor, it’ll be solely throught your computer system in my case I’m using my laptop.

[HowTo] Wireless Bridging with Routers

Router Bridging

Cables are fun as long as they don’t tangle or become a pain for you, a popular technology called WiFi eases this pain by sending data via Radio waves instead of cables.

Now we don’t usually use WiFi with desktops but what if you want to do so with ROUTERS? Yes, you can connect two routers Wireless-ly or as we say “Bridge” them together. Setting up a Bridging routers is easy but you’ll need to ensure some goals that are:

1) Router which supports DD-WRT Firmware
2) Router installed with latest DD-WRT Firmware
3) A primary Router connected to your main internet line

Securing your WiFi Network

Hello guys, In this tutorial we’ll be discussing how to secure your WiFi from Intruders, Crackers etc. Here’s a list of stuff that we are going to discuss in this tutorial:

- Router Features
- Strong Encryption
- Low WiFi Strength and Proximity
- MAC Filtering
- Strong Password
- Hiding WiFi SSID
- Deactivate WPS
- Upgrading Your Firmware

Router Features

The first most step towards security is to see whether your device has the appropriate features to make itself secure. As for Routers especially the one’s with WiFi. Security features are a must to avoid intruders to break in and take pleasure of your shit 😛
Always choose a Router which has most of the Security Features, Some of the important one’s I’ll list below:

Introduction to Merge Sort

What is Merge Sort?

t is a sorting algorithm which uses comparison operator (=<) to choose which items of the 2 should be placed first, In fact it uses a well known method of “Divide and Conquer” to perform it’s task.

Since the term MergeSort has 2 parts:

1) Merge
2) Sort

So I’ll be explaining each part first and then will explain as whole In this way you’ll under this better.

Introduction to Sorting and Sorting Algorithm

*Bold items indicate importance

Hello guys and girls!

Today I will introduce to an important topic in Computer Science and that is Sorting, I will try to explain as easy as I can for user understanding. We will also be explaining 2 related algorithms that make our work more easier but be aware that I’ve written the Algorithm code in Python 3.3 so be sure to have a Python understanding. So first lets see what Sorting is?

What is Sorting?

Lets take an example of a List of Names:

names = ['Deque', 'bluedog.tar.gz', 'Arkphaze', 'Hackcommunity', 'noize', 'Linuxephus']

Now you can see that each name has a different length and can be arranged by either placing them from Short Length to Long Length

Intro to Python Strings

In python strings are represented by enclosing them between

1) Single Quote ‘ ‘
2) Double Quote ” “
3) Triple  Quote ”’ ”’

For example:

‘WordPress’, “Procurity”  

Those two are basically python strings. We will discuss Triple Quote in later lessons as they are used mainly for description.

In this tutorial we will discuss:

1) String Indexing

2) Slicing Strings

3) String Concantation

4) String Formatting
