In this article, we would like to introduce to you another useful command-line based interface to git called Tig.

Tig is a free open source, cross platform ncurses-based text-mode interface for git. It is a straight-forward interface to git that can help in staging changes for commit at chunk level and works as a pager for output from different Git commands. It can run on Linux, MacOSX as well as Windows systems.

How to Install Tig in Linux Systems

To install Tig in Linux, you need to first clone the Tig repository to your system and install it as shown.

$ git clone git://github.com/jonas/tig.git
$ make
$ make install

By default, tig will be installed under $HOME/bin directory, but ff you wish to install it in another directory under in your PATH, set prefix to the desired path, as shown.

$ make prefix=/usr/local
$ sudo make install prefix=/usr/local

Once you have installed Tig on your system, using the cd command get into your any of your local git repositories and run tig without any arguments, which should show all commits for the repository.

$ cd ~/bin/shellscripts/
$ tig  

To quit Tig, press q to close it.

Display Repository Activity Log

To display a log activities of the above repository, use the log sub-command.

$ tig log

Show Repository Objects

The show sub-command allows you to display one or more objects such as commits and many more, in a more detailed way, as shown.

$ tig show commits

Search A Pattern/Word in Git Files

You can also search for a particular pattern (for example the word check) in your git files with the grep sub-command, as shown.

$ tig grep check 

Display Git Repository Status

To display status of your git repository use status sub-command as shown.

$ tig status

For more Tig usage, please refer to help section or visit the Tig Github repository at https://github.com/jonas/tig.

$ tig -h

Tig is a simple ncurses-based interface to git repositories and mainly act as a Git repository browser. Give us your feedback or ask any questions via the comment form below.

Etherpad is a web based free document editor tool which allows a group of users to work jointly on a document in a real time, like a multi player editor which runs on a web browser. Etherpad authors can edit and at the same time see each others edits in real time with a capability to display author’s text in their own colours.

This tool has a separate chat box in the sidebar allowing authors to communicate during editing. Etherpad is written in JavaScript both on server side and client side, so that it comes easy for developers to maintain and add new features.

Etherpad is designed in such a way that you can have access to all data through a well-documented HTTP API. This software also helps you to import/export data to many exchange formats and comes with translations too where authors can deliver correct language for their local settings.

For your reference, I’ve attached a Demo of Etherpad Lite at below link.

1. Watch EtherPad Demo

In this tutorial, I will describe how to install and configure Etherpad Lite a web-based real time collaborative document editing application on RHEL, CentOS, Fedora, Debian, Ubuntu and Linux Mint.

Installing Etherpad Lite on Linux

First, we need to download and install few required libraries and development tools. Open the terminal and run the following command either as root or by adding sudo at the beginning of each command.

Step 1: Install Libraries and Development Packages

You’ll need gzip, git, curl, libssl python, develop libraries, python and gcc packages.

On RHEL / CentOS / Fedora

# yum install gzip git-core curl python openssl-devel && yum groupinstall "Development Tools" For FreeBSD: portinstall node, npm, git

On Debian / Ubuntu / Linux Mint

$ sudo apt-get install gzip git-core curl python libssl-dev pkg-config build-essential

Step 2: Install Node.js

Additionally, you will also need to download and compile latest stable Node.js version from source packages using following commands.

$ wget http://nodejs.org/dist/node-latest.tar.gz
$ tar xvfvz node-latest.tar.gz
$ cd node-v0.10.23     [Replace a version with your own]
$ ./configure
$ make
$ sudo make install

Once you have successfully installed, verify the Node.js version using the command as follows.

$ node --version

v0.10.23

Step 3: Download and Install Etherpad Lite

We will create a separate user called “etherpad” to run Etherpad application independently. So, first create a user with its home directory.

# useradd --create-home etherpad

Now switch to “etherpad” user and download the latest stable version of Etherpad Lite using GIT repository as shown.

# su - etherpad
$ cd /home/etherpad
$ git clone http://github.com/ether/etherpad-lite.git

Once you’ve downloaded source files, change into the newly created directory containing the cloned source code.

$ cd etherpad-lite/bin

Now, execute run.sh script.

$ ./run.sh

Sample Output

Copy the settings template to settings.json...
Ensure that all dependencies are up to date...  If this is the first time you have run Etherpad please be patient.
[2013-12-17 05:52:23.604] [WARN] console - DirtyDB is used. This is fine for testing but not recommended for production.
[2013-12-17 05:52:24.256] [INFO] console - Installed plugins: ep_etherpad-lite

[2013-12-17 05:52:24.396] [INFO] console - You can access your Etherpad instance at http://0.0.0.0:9001/
[2013-12-17 05:52:24.397] [WARN] console - Admin username and password not set in settings.json.  To access admin please uncomment and edit 'users' in settings.json

Step 4: Access and Create New Pad in Etherpad Lite

Now you should able to browse the web interface of Etherpad Lite at http://localhost:9001 or http://your-ip-address:9001 in a web browser.

Create a new document by giving a Pad name. Please remember, enter new name when creating a new document or enter name of the previously edited document to access.

For example, I’ve created a new document called “tecmint”. User’s can create multiple new pads in separate windows, each user’s document window appears on another window automatically in real-time. Each user’s window is highlighted in two different colours and also user’s can interact with each other using built-in chat box.

Each newly created document has its own URL structure. For example, my new “tecmint” pad get’s a URL as http://your-ip-address:9001/p/tecmint. You can share this document URL with your friends and colleagues. You can even embed the editor window into another HTML web page as an iframe.

You can save the document while editing is in progress by clicking the STAR button, however they are created periodically. To access a saved revision of the document add the number of the saved revision. For example, if you would like to see the saved revision number (i.e. 2) in this case, replace the number 6 with 2 at the http://your-ip-address:9001/p/tecmint/6/export/text.

Etherpad also comes with built-in feature called import and export, where you can import any external document or export a current saved document to a separate file. The document can be downloaded in HTML, Open Document, Microsoft Word, PDF or Plain text format.

A “time slider” feature enables anyone to explore the history of the pad.

Step 5: Using Etherpad Lite with MySQL Backend

By default Etherpad stores documents in a flat-file database. I suggest you to use MySQL as a backend to store created and edited documents. For this, you must have MySQL installed on your system. If you don’t have, install it on the system, you can install it using following commands as root user or using sudo.

On RHEL / CentOS / Fedora

# yum install mysql-server mysql
# service mysqld start
# chkconfig mysqld on

On Debian / Ubuntu / Linux Mint

# apt-get install mysql-server mysql-client
# service mysqld start

After MySQL has installed, connect to mysql shell by running a following command.

# mysql -u root -p

Once you in mysql shell, issue the following command to create the database.

create database etherpad_lite;

Grant permissions to a newly created database account. Replace “your-password” with your own password.

grant all privileges on etherpad_lite.* to 'etherpad'@'localhost' identified by 'your-password';

Leave the mysql client.

exit;

Now, switch to “etherpad” user and go into the etherpad directory and run the following commands:

# su - etherpad
$ cd /home/etherpad/etherpad-lite    
$ cp settings.json.template settings.json

# vi settings.json

"sessionKey" : "",

"sessionKey" : "Aate1mn160",

"dbType" : "dirty",
  //the database specific settings
  "dbSettings" : {
                   "filename" : "var/dirty.db"
                 },

// "dbType" : "dirty", */
  //the database specific settings
  // "dbSettings" : {
  //                   "filename" : "var/dirty.db"
  //                 },

  /* An Example of MySQL Configuration
   "dbType" : "mysql",
   "dbSettings" : {
                    "user"    : "etherpad",
                    "host"    : "localhost",
                    "password": "your-password",
                    "database": "etherpad_lite"
                  },

  */
  "users": {
    "admin": {
      "password": "your-password",
      "is_admin": true
    },

./bin/installDeps.sh

./bin/run.sh

mysql -u root -p
alter database etherpad_lite character set utf8 collate utf8_bin;
use etherpad_lite;
alter table store convert to character set utf8 collate utf8_bin;
exit;

./bin/run.sh

Alfresco is an open source ECM system (Enterprise Content Management) written in Java which provides electronic management, collaboration and business control.

This guide will cover how to install and configure Alfresco Community Edition on RHEL/CentOS 7/6, Debian 8and Ubuntu systems with Nginx server as a frontend web server for the application.

Requirements

As for the minimum system requirements, Alfresco needs a machine with at least 4 GB of RAM and a 64-bit Operating System.

Step 1: Install Alfresco Community Edition

1. Before proceeding with Alfresco installation first assure that wget utility is installed on your machine by issuing the below command with root privileges or from root account.

# yum install wget
# apt-get install wget

2. Next, setup your system hostname and assure that local resolution points to your server IP Address by issuing the following commands:

# hostnamectl set-hostname server.alfresco.lan
# echo “192.168.0.40 server.alfresco.lan” >> /etc/hosts

3. Remove any MTA from the machine (in this case Postfix Mail server) by issuing the below command:

# yum remove postfix
# apt-get remove postfix

4. Install the following dependencies required by Alfresco software in order to run properly:

# yum install fontconfig libSM libICE libXrender libXext cups-libs
# apt-get install libice6 libsm6 libxt6 libxrender1 libfontconfig1 libcups2

5. Next, go to Alfresco Community Edition repository page hosted on sourceforge.net portal and grab the latest binary version (i.e. alfresco-community-5.0.d-installer-linux-x64.bin) for Linux using wget utility.

# wget http://nchc.dl.sourceforge.net/project/alfresco/Alfresco%205.0.d%20Community/alfresco-community-5.0.d-installer-linux-x64.bin

6. After the binary file download finishes, issue the following command in order to grant execution permissions for the file and run alfresco installer.

# chmod +x alfresco-community-5.0.d-installer-linux-x64.bin
# ./alfresco-community-5.0.d-installer-linux-x64.bin

7. After the installation process starts, select the language and continue the installation process by using the below installation wizard as a guide to configure Alfresco:

8. After the installation process finishes and Alfresco services are started issue the below commands in order to open the following firewall ports to allow external hosts in your network to connect to the web application.

# firewall-cmd --add-port=8080/tcp -permanent
# firewall-cmd --add-port=8443/tcp -permanent
# firewall-cmd --add-port=7070/tcp -permanent
# firewall-cmd --reload

In case you need to add other firewall rules to open ports in order to access custom Alfresco services issue the ss command to get a list of all the services running on your machine.

# ss -tulpn

9. To access Alfresco web services, open a browser and use the following URLs (replace the IP Address or domain accordingly). Login with admin user and the password configured for Admin through the installation process.

http://IP-or-domain.tld:8080/share/ 

http://IP-or-domain.tld:8080/alfresco/ 

For WebDAV.

http://IP-or-domain.tld:8080/alfresco/webdav 

For HTTPS accept the security exception.

https://IP-or-domain.tld:8443/share/ 

Alfresco SharePoint Module with Microsoft.

http://IP-or-domain.tld:7070/

Step 2: Configure Nginx as Frontend Web Server for Alfresco

10. In order to install Nginx server on the system, first add Epel Repositories on CentOS/RHEL by issuing the below command:

# yum install epel-release

11. After Epel repos are added into the system proceed with Nginx web server installation by issuing the following command:

# yum install nginx       [On RHEL/CentOS Systems]
# apt-get install nginx   [On Debian/Ubuntu Systems]  

12. On the next step open Nginx configuration file from /etc/nginx/nginx.conf with a text editor and make the following changes:

location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

Go below and make sure you comment the second location statement by placing a # in front of the following lines:

#location / {
#        }

13. After you’re done, save and close Nginx configuration file and restart daemon to reflect change by issuing the following command:

# systemctl restart nginx.service

14. In order to access Alfresco web interface add a new firewall rule to open port 80 on your machine and navigate to the below URL. Also, make sure Selinux policy is disabled on RHEL/CentOS systems.

# firewall-cmd --add-service=http -permanent
# firewall-cmd --reload
# setenforce 0

To completely disable Selinux policy on the system, open /etc/selinux/config file and set the line SELINUX from enforcing to disabled.

15. Now you can access Alfresco through Nginx.

 http://IP-or-domain.tld/share/ 
 http://IP-or-domain.tld/alfresco/
 http://IP-or-domain.tld/alfresco/webdav 

15. In case you want to securely visit Alfresco web interface through Nginx proxy with SSL, create a Self-Signed Certificate for Nginx on /etc/nginx/ssl/ directory and fill the certificate with your custom settings as illustrated on below screenshot:

# mkdir /etc/nginx/ssl
# cd /etc/nginx/ssl/
# openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout alfresco.key -out alfresco.crt

Pay attention to Certificate Common Name to match your domain hostname.

17. Next, open Nginx configuration file for editing and add the following block before the last closing curly bracket (the } symbol).

# vi /etc/nginx/nginx.conf

Nginx SSL block excerpt:

server {
    listen 443;
    server_name _;

    ssl_certificate           /etc/nginx/ssl/alfresco.crt;
    ssl_certificate_key       /etc/nginx/ssl/alfresco.key;

    ssl on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    access_log            /var/log/nginx/ssl.access.log;

      location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
## This is the last curly bracket before editing the file. 
  }

18. Finally, restart Nginx daemon to apply changes, add a new firewall rule for 443 port.

# systemctl restart nginx
# firewall-cmd -add-service=https --permanent
# firewall-cmd --reload

and instruct the browser to your domain URL using the HTTPS protocol.

https://IP_or_domain.tld/share/
https://IP_or_domain.tld/alfresco/

19. In order to enable Alfresco and Nginx daemons system-wide run the below command:

# systemctl enable nginx alfresco

That’s all! Alfresco offers integration with MS Office and LibreOffice via CIFs protocol providing a familiar workflow for users.

In this busy world we have little time for anything other than our work. Leisure from work recharges us. The small break we take in-between our job which may extend from a few minutes to some hour is utilized by us in the task we love and appreciate. It again ranges from – Cracking Jokes, Playing, sleeping or watching daily soaps and Movies.

Watching Movies is liked by most of us. We rely on Television or Various Video Streaming websites (YouTube, Metacafe, etc) to watch movies. In TV we don’t have choice and on Video Streaming website you rarely gets a latest movie. How about something that gives you an interface to watch daily soaps and Movies of your choice of all genres with lots of Language Support?

Here comes a tool ‘Popcorn Time‘ which performs all the above discussed function and the performance of which is out-of-box.

What is Popcorn Time?

Popcorn Time is a Free and Open Source Software released under General Public License and written in programming languages which includes – HTML, JavaScript and CSS, which streams video on-line for free without the need of filling silly forms or adding your credit card details. It is available for all major operating platforms including Linux, Mac OS and Windows.

Features of Popcorn Time

1. Great Movies Availability.
2. No Restriction and you can watch Movies as many times as you want.
3. Awesome Catalog – Automatically finds best version available and starts streaming it.
4. Best Quality – Stream HD Movie, Instantaneously.
5. Drag-and-Drop subtitles ‘.srt files’.
6. Supports 44 Different Languages.
7. Icons and Links for ‘About Dialog’ – Better presentation.
8. Full Window Supported.
9. Added a Help for Key Board Shortcuts.
10. Quality Filter for Movies.
11. Search box to search movies.

How Popcorn Time Works?

The movies in Popcorn time is streamed using bittorrent Protocol. The Application program streams pirated movies directly from torrent trackers. The User Interface of Popcorn Time enables a user to search movies based upon a huge genre and categories. The film is presented in Thumbnails along with the Film Title, their ratings, Year, a small review and the subtitles availability in various Languages. It has a ‘WATCH IT NOW‘ button which makes it possible to stream the movie instantaneously without any formality.

Popcorn Time is used all around the globe in all the countries including those two countries who does not have INTERNET connection as reported by Popcorn time Official site. In some countries the users were getting legal threats against pirated movies. To FIX this Popcorn Time now has encrypted its BitTorrent Traffic and Included VPN service which ensures the identity of third party users can no longer be traced thus avoiding unnecessary risk.

The other side of the story…

Streaming of pirated movies brought this application in debate if this is legal or illegal. We are not going to discuss if this is legal or not and for a FOSS Enthusiastic it rarely means anything. Well the controversy of streaming illegal pirated movies forced its developers to discontinue the project and as a result on March 14th of 2014, the official website of Popcorn Times and GitHub Repository were removed.

Popcorn Time announced that it was ceasing operations, in a blog post at http://getpopcornti.me/.

“Popcorn Time is shutting down today. Not because we ran out of energy, commitment, focus or allies. But because we need to move on with our lives.

Our experiment has put us at the doors of endless debates about piracy and copyright, legal threats and the shady machinery that makes us feel in danger for doing what we love. And that’s not a battle we want a place in.

Later the Announcement

The development of Popcorn Time was taken over by two team and since then this project again moved into ‘Active‘ stage. At this point of time both the groups carrying out the development of Popcorn time uses their own and distinct websites. One is popcorntime.io and the other is Time4Popcorn.eu.

Installation of Popcorn Time in Linux

Download Popcorn Time source tarball package (latest version 0.3.7.2) from any of the two developers’ group website.

1. http://popcorntime.io/
2. http://time4popcorn.eu/

Alternatively, you may also use wget command to download tarballs directly in your terminal.

Note: You must have ‘xz-utils‘ package installed on the system to extract the ‘xz‘ format tarball. If not, install the package xz-utils using yum or apt package manager.

On 32-Bit Systems

$ wget https://get.popcorntime.io/build/Popcorn-Time-0.3.7.2-Linux32.tar.xz
$ tar -xvf Popcorn-Time-0.3.7.2-Linux32.tar.xz 
# cd Popcorn-Time/
$ chmod 755 Popcorn-Time 
./Popcorn-Time

On 64-Bit Systems

$ wget https://get.popcorntime.io/build/Popcorn-Time-0.3.7.2-Linux64.tar.xz
$ tar -xvf Popcorn-Time-0.3.7.2-Linux64.tar.xz 
# cd Popcorn-Time/
$ chmod 755 Popcorn-Time 
./Popcorn-Time

Note: In my Debian Jessie (sid/Testing) x86_64 architecture processor. I got the below warning message when I tried running Popcorn-Time.

$ ./Popcorn-Time 

./Popcorn-Time: error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory

I’ve fixed, by creating a symbolic link tolibudev.so.1 to libudev.so.

$ ln -sf /lib/x86_64-linux-gnu/libudev.so.1 /lib/x86_64-linux-gnu/libudev.so.0

After that fix, I again tried running Popcorn-Time and I run without any glitch.

Testing Popcorn Time

Please accept the terms of service.

The second window says “This Popcorn Time Service will Never be taken Down. Enjoy”.

Reprepro is a small command-line tool to create and manage .deb repositories easily, Today we’ll be showing how to create a Debian package repositories easily using reprepro and how to upload it to Sourceforge.net using rsync command.

Step 1: Install Reprepro and Generate Key

First, install all the necessary packages, using the following apt-get command.

$ sudo apt-get install reprepro gnupg

Now you need to generate a gpg key using gnupg, to do this, apply this command.

$ gpg --gen-key

It will ask you some questions, like the kind of the key you want, how long the key should be valid, if you don’t know what to answer, just click Enter for the default options (recommended).

Of course, it will ask you for a username and a password, keep those in mind, because we will need them later.

gpg (GnuPG) 1.4.14; Copyright (C) 2013 Free Software Foundation, Inc.
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.

Please select what kind of key you want:
   (1) RSA and RSA (default)
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)
Your selection? 
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) 
Requested keysize is 2048 bits
Please specify how long the key should be valid.
         0 = key does not expire
        = key expires in n days
      w = key expires in n weeks
      m = key expires in n months
      y = key expires in n years
Key is valid for? (0) 
Key does not expire at all
Is this correct? (y/N) Y

You need a user ID to identify your key; the software constructs the user ID
from the Real Name, Comment and Email Address in this form:
    "Heinrich Heine (Der Dichter) <heinrichh@duesseldorf.de>"

Real name: ravisaive
Email address: tecmint.com@gmail.com
Comment: tecmint
You selected this USER-ID:
    "Ravi Saive (tecmint) <tecmint.com@gmail.com>"

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
You need a Passphrase to protect your secret key.

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

sub   2048R/7EF2F750 2014-06-24

Now your key will be generated, to Check if so, run this command as a root privileges.

$ sudo gpg --list-keys

Sample Output

/home/ravisaive/.gnupg/pubring.gpg
----------------------------------
pub   2048R/2EB446DD 2014-06-24
uid                  ravisaive (tecmint) <tecmint.com@gmail.com>
sub   2048R/7EF2F750 2014-06-24

Step 2: Create a Package Repository and Export Key

We’ll start the work now to create the repository, first you have to create some folders, our repository will be in /var/www/apt directory, so let’s create some folders.

$ sudo su
# cd /var/www
# mkdir apt
# mkdir -p ./apt/incoming 
# mkdir -p ./apt/conf
# mkdir -p ./apt/key

You have now to export the key you created to the repository folder, run.

# gpg --armor --export username yourmail@mail.com >> /var/www/apt/key/deb.gpg.key

Note: Replace username with the username you entered in above step, and yourmail@mail.com with your email.

We need to create a file called “distributions” inside /var/www/apt/conf.

# touch /var/www/apt/conf/distributions

Add these following lines to the distributions file and save the file.

Origin: (yourname)
Label: (name of repository)
Suite: (stable or unstable)
Codename: (the codename for the distribution you are using, like trusty)
Version: (the version for the distribution you are using, like 14.04)
Architectures: (the repository packages  architecture, like i386 or amd64)
Components: (main restricted universe multiverse)
Description: (Some information about the repository)
SignWith: yes

Next, We’ll have to create the repository tree, to do this, run those commands.

# reprepro --ask-passphrase -Vb /var/www/apt export

Sample Output

Created directory "/var/www/apt/db"
Exporting Trusty...
Created directory "/var/www/apt/dists"
Created directory "/var/www/apt/dists/Trusty"
Created directory "/var/www/apt/dists/Trusty/universe"
Created directory "/var/www/apt/dists/Trusty/universe/binary-i386"
FF5097B479C8220C ravisaive (tecmint) <tecmint.com@gmail.com> needs a passphrase
Please enter passphrase:
Successfully created '/var/www/apt/dists/Trusty/Release.gpg.new'
FF5097B479C8220C ravisaive (tecmint) <tecmint.com@gmail.com> needs a passphrase
Please enter passphrase:
Successfully created '/var/www/apt/dists/Trusty/InRelease.new'

Step 3: Add Packages to Newly Created Repository

Now prepare your .deb packages to be added to the repository. Go to the /var/www/apt directory, you have to do this each time you want to add packages.

# cd /var/www/apt
# reprepro --ask-passphrase -Vb . includedeb Trusty /home/ravisaive/packages.deb

Note: Replace trusty with the codename you entered for the repository in the distributions file, and replace /home/username/package.deb with the path to the package, you will be asked for the passphrase to enter.

Sample Output

/home/ravisaive/packages.deb : component guessed as 'universe'
Created directory "./pool"
Created directory "./pool/universe"
Created directory "./pool/universe/o"
Created directory "./pool/universe/o/ojuba-personal-lock"
Exporting indices...
FF5097B479C8220C ravisaive (tecmint) <tecmint.com@gmail.com> needs a passphrase
Please enter passphrase:
Successfully created './dists/Trusty/Release.gpg.new'
FF5097B479C8220C ravisaive (tecmint) <tecmint.com@gmail.com> needs a passphrase
Please enter passphrase:
Successfully created './dists/Trusty/InRelease.new'

Your package is added to the repository, to remove it.

# reprepro --ask-passphrase -Vb /var/www/apt remove trusty  package.deb

And of course, you need to modify the command with your package name and the repository codename.

Step 4: Upload Repository to Sourceforge.net

To upload the repository to Sourceforge.net, you need to have a running account there of course, and a running project, let’s assume that you want to upload the repository to http://sourceforge.net/projects/myfoo/testrepository where myfoo is your project name (UNIX name, not URL, not the Title), and testrepository is the folder where you want to upload the files into, We will do this using rsync command.

# rsync -avP -e ssh /var/www/apt/ username@frs.sourceforge.net:/home/frs/project/myfoo/testrepository/

Note: Replace username with your username on sourceforge.net and myfoo with your project UNIX-name and testrepository with the folder you want to store the files in.

Now thats your repository is uploaded to http://sourceforge.net/projects/myfoo/testrepository, to add it to your installed system, first you have to import the repository key, it will be in /var/www/apt/key/deb.gpg.key, but that’s a local path and the users for your repository won’t be able to add it to their systems, thats why we’ll be importing the key from sourceforge.net.

$ sudo su
# wget -O - http://sourceforge.net/projects/myfoo/testrepository/apt/key/deb.gpg.key | apt-key add -

You can add the repository easily now to your system, open /etc/apt/sources.list and add this line.

deb http://sourceforge.net/projects/myfoo/testrepository/apt/key/deb.gpg.key trusty main

Note: Replace myfoo with your project UNIX-Name, trusty with your repository codename, testrepository with the folder you uploaded the files into, and main with repository components you added to the distributions file.

Next, run following to update the repositories list.

$ sudo apt-get update

Congratulations! Your repository is active! You can now install packages easily from it if you want.

Libav is a set of cross-platform libraries and tools that are used to deal with multimedia files, streams and protocols, it was originally forked from the ffmpeg project. Libav includes many sub-tools like:

1. Avplay: a video & audio player.
2. Avconv: a multimedia converter plus a video & audio recorder from different sources.
3. Avprobe: a tool that connects to the multimedia file stream and returns many useful information and statistics about it.
4. Libavfilter: a filtering API for different Libav tools.

In this article, we’ll explain how to record the Linux desktop’s video & audio using the ‘Avconv’ program on Debian/Ubuntu/Linux Mint distributions.

Step 1: Installing Avconv Tool

1. avconv is a part from the “libav-tools” package, which is available to install from the official repositories for all Debian-based distributions like Ubuntu and Mint, using following commands.

$ sudo apt-get update
$ sudo apt-get install libav-tools

Note: Installing packages from default repositories, might give you a little older version of ‘avconv‘ tool. Thus, we recommend you to get the latest version from the official git repository, as shown below.

$ sudo apt-get install yasm
$ git clone git://git.libav.org/libav.git
$ cd libav
$ ./configure
$ make
$ sudo make install

Note: You will have to run “./configure –help” in order to list all the available options for the configuration file and install codecs and libraries that you want, you will also need to do a lot of work in order to install the dependencies.

Also note, if you’re used the compile-from-source way, you’ll always have to use “sudo avconv” instead of “avconv” to run the tool.

Step 2: Start Video Recording of Desktop

2. You’re ready now, all what you have to do is to record your desktop video by issuing following command.

$ avconv -f x11grab -r 25 -s 1920x1080 -i :0.0 -vcodec libx264 -threads 4 $HOME/output.avi

Now let’s explain the command in short:

1. avconv -f x11grab is the default command to capture video from the X server.
2. -r 25 is the frame rate you want, you may change it if you like.
3. -s 1920×1080 is your system’s screen resolution, change it to your current system resolution, it’s very important to do this.
4. -i :0.0 is where we want to set our recording start point, leave it like this.
5. -vcodec libx264 is the video codec that we’re using to record the desktop.
6. -threads 4 is the number of threads, you may change it as well if you like.
7. $HOME/output is the destination path where you want to save the file.
8. .avi is the video format, you may change it to “flv”, “mp4”, “wmv”, “mov”, “mkv”.

3. After you enter the command, the recording will start automatically as a process running from the terminal, in order to stop it, hit “Ctrl + C” keys inside the terminal window.

4. Now, you may run the file using VLC or any other multimedia player, or you may run it using “avplay” tool which is a multimedia player from the same Libav package.

$ avplay $HOME/output.avi

Note: Don’t forget to replace the destination file path. The recording’s quality is pretty good.

Here’s a video that I’ve recorded using the “avconv” tool.

Step 3: Start Video & Audio Recording of Desktop

5. If you want to record the audio as well, first run this command to list all the available input sources for the audio.

$ arecord -l

It will give you some output like this.

In my case, I’ve one input source for audio only, and its number is “1”, that’s why I am going to use the following command to capture both video & microphone audio.

$ avconv -f alsa -i hw:1 -f x11grab -r 25 -s 1920x1080 -i :0.0 -vcodec libx264 -threads 4 output-file2.avi

$ avconv -f alsa -i hw:1 out.wav

$ sudo apt-get update
$ sudo apt-get install libav-tools

$ avconv -i Michael-Jackson-You-Rock-My-World-HD.mp4

linuxmessenger app is a “Facebook-like” client for Linux desktop was written in Python language. It allows you to login to your Facebook account right from the command line without installing it on your system and have chat with your loved ones with much a like a Facebook interface. If you want, you can install it as a desktop client. This application has some built-in features like desktop notifications, pop-up alert, friends request and chat sound (with On/Off options).

Installing Facebook Messenger

The installation is very straightforward, simply open the terminal and install python3, PyQt4 dependencies packages required by the application to run.

# apt-get install python-setuptools python3-setuptools python-qt4-phonon python-qt4-phonon python3-pyqt4.phonon

Next, download the linuxmessenger zip file from the github page, using wget command. Once downloaded, extract it to your desired directory or home directory. You should get the folder similar to “linuxmessenger-master”.

# wget https://github.com/oconnor663/linuxmessenger/archive/master.zip
# unzip master.zip

To verify, whether application is working, Go to the extracted folder “linuxmessenger-master” and run the “fbmessenger” script file.

# cd linuxmessenger-master/
# ./fbmessenger

A “Facebook Messenger” window opens, Enter your Facebook login credentials and chat with your friends.

If you would like to install this application as a desktop client, simply run the “setup.py” script or you just execute the “fbmessenger” from the terminal and have everything as desktop client.

# ./setup.py install

There are also builds for RPM based and Debian distributions, so you can install and build it on most distro. As I said the script written in Python language, so it should work on all Linux platforms as long as required dependencies packages are fulfilled.
