How To Open an EPUB File in Linux or Windows system

2014-03-02T08:08:00.001-08:00

Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with

How To Convert an EPUB File:

There are three main ways to attempt to convert an EPUB file to another file type:

Open the EPUB file in its default program and choose to save the open file as another file format.
Download Calibre for free and use it to convert EPUB files to and from other eBook formats, including ones compatible with the Amazon Kindle.
Use another File Conversion Online Service or Software Program to convert the EPUB file to another file format.

EPUB files are structured just like ZIP files, meaning that you can rename an EPUB eBook, replacing the .epub with .zip, and then open the file with your favorite file compression program, like the free 7-Zip tool. Inside you should find the contents of the EPUB eBook in HTML format, as well as the images and styles used to create the EPUB file.

Install Aircrack-ng on Ubuntu 12.04

2014-02-23T06:09:00.000-08:00

Installing Aircrack-ng on Ubuntu 12.04

A variable called -Werror. This is what you need to do to compile aircrack-ng without the pesky errors.

sudo apt-get install build-essential
sudo apt-get install libssl-dev
wget http://download.aircrack-ng.org/aircrack-ng-1.1.tar.gz
tar -zxvf aircrack-ng-1.1.tar.gz
cd aircrack-ng-1.1

In the aircrack-ng-1.1 directory there is a file called common.mak, use your favorite editor to open the file and scroll down till you see the following line:

CFLAGS ?= -g -W -Wall -Werror -O3

Delete the -Werror variable, so that the line now looks like the following. Save and exit.

CFLAGS ?= -g -W -Wall -O3

Run make and make install to get aircrack-ng up and running.

How to access Linux Ext3/Ext4 File System in Windows

2014-02-03T06:17:00.003-08:00

While using Linux distros such as Ubuntu, Fedora you can easily access Windows NTFS file system. But this is not possible when you are working with Windows. You cannot even view the Linux Ext3/Ext4 file system in Windows. To solve this problem I recently came across a tool called Linux Reader which was very helpful in accessing Linux files in Windows. This tool works perfectly as you can copy the files from the Ext3/Ext4 file system to your Windows NTFS file System.

Download and install Linux Reader from http://www.diskinternals.com/linux-reader/ or u can download this one form my own store http://u-store.no-ip.biz/
(For this server u have to request ... its not always on-line)

Open the installed Linux reader. It scans and displays your partitions including the Linux Ext3/Ext4 one.The partition which is indicated by “/” is our Linux root partition. It displays every Linux partition with the path it ismounted. My other Linux Partition is displayed as “/rajamalw/media/xxxx” which is the path it is mounted.

It has a inbuilt image viewer so that you can use it to view images without using any additional tools.

Copying Files to Windows

To copy or save a file to Windows partition right click on the item and select save. It will guide you through a wizard to complete the process.

Creating Images

You can completely backup a Linux partition in Windows. Right click on the partition and select Create Image. It would take some time according to the partition size.

This would be a all in one tool for all your needs.
