Social Media Player for Linux, Windows and MAC OSX - Tomahawk

Tomahawk is a project dedicated to creating an audio player as an alternative Banshee, Amarok, and Rhytmbox. Tomahawk interface looks clean and fits perfectly on any desktop environment such as Gnome, KDE, Xfce, and LXDE. Tomahawk can be installed on MAC OSX, Linux and Windows

Tomahawk is build to solve below mentioned problems:
* Why can't I easily listen to all the music I have scattered across multiple computers, at multiple locations, from a single interface?
* Why can I stream my home iTunes library to my laptop when I am at home, but I can't when I am somewhere else?
* Conversely, how come I can stream my co-worker's iTunes library when we are both at the office, but only if we are on the same wireless network (or subnet)?
* When I am reading a website that talks about a song, and I own that song, why can't I play my copy directly from that page?
* Why can't I subscribe to, and import, playlist metadata from all over the web - and then have that resolve against any/all songs that I have access to?
* Why do I have to listen to songs I have on my hard drive, and songs from services I subscribe to, in totally different user experience silos?
* If I am a music subscription service provider, why do I need to incur the costs of streaming you content you already have locally?

Find and Delete Duplicate files under Linux - Fdupes

fdupes is a program written by Adrian Lopez to scan directories for duplicate files, with options to list and delete them. It first compares file sizes and MD5 signatures, and then performs a byte-by-byte check for verification.
fdupes is written in C and is released under the MIT License.

fdupes installation:
Type the following command to install fdupes in Debian / Ubuntu Linux:

sudo apt-get install fdupes

Protects Networked Hosts from Brute Force Attacks - Sshguar

Sshguard is a small program that monitors services running on your machine from the log files. When it detects that someone is doing something bad to a service, sshguard blocks the IP address of the bad guy with a firewall rule.

Sshguard Log support:
Sshguard interprets log messages with several formats:
* syslog
* syslog-ng
* metalog
* multilog
* raw log
It can monitor multiple log files at once, and handles log rotation and temporary log files automatically. Its powerful grammar-based parser makes it straightforward to support several formats and services without increasing complexity.

Extracting Images from PDF files - Pdfimages

Pdfimages is an open source command-line utility for extracting images from PDF files. It is freely available as part of poppler-utils and xpdf-utils, and included by default with many Linux distributions.

Pdfimages saves images from a Portable Document Format (PDF) file as Portable Pixmap (PPM), Portable Bitmap (PBM), or JPEG files. Pdfimages reads the PDF file, scans one or more pages, PDF-file, and writes one PPM, PBM, or JPEG file for each image, image-root-nnn.xxx, where nnn is the image number and xxx is the image type (.ppm, .pbm,.jpg).

NB: pdfimages extracts the raw image data from the PDF file, without performing any additional transforms. Any rotation, clipping, color inversion, etc. done by the PDF content stream is ignored.
