Setup Arduino on CentOS 7

Here I will Show you how you can start your Arduino on Linux CentOS 7.

First you need following:

1. Arduino device

2. USB Cable for Arduino

3. Arduino IDE – Free download from : http://arduino.cc/en/Main/Software

The RXTX that comes with Arduino was modified to support devices of the form /dev/ttyACM*, which are used by the Arduino Uno and Mega 2560 boards (which use an ATmega8U2 instead of an FTDI chip for USB-serial communication)

The RXTX library requires that you specify the serial ports.

Arduino’s (and other USB-serial devices) end up as /dev/ttyUSB# or /dev/ttyACM#.

when you start Arduino IDE first time you may see this error when upload code to device:

error message is: Serial port COM1 not found. Did you select the right one from the Tools > Serial Port menu?

And when you go to select the Serial Port, the option Tools > Serial Port is greyed out

So lets Fix this Error and start your Ardunio on CentOS 7

Plug your arduino, then from terminal:

# dmesg | tail

you will see something like (for arduino < UNO):

[rsharma@localhost ~]$ dmesg | tail
[ 1373.684427] wlo1: associate with 48:f8:b3:23:7c:b1 (try 1/3)
[ 1373.688116] wlo1: RX AssocResp from 48:f8:b3:23:7c:b1 (capab=0x411 status=0 aid=3)
[ 1373.691558] wlo1: associated

[ 2221.757248] cdc_acm 2-1.1:1.0: ttyACM0: USB ACM device
[rsharma@localhost ~]$

# lsusb

the output will be similar to this:

[rsharma@localhost ~]$ lsusb

look for arduino or FTDI(if prior arduino UNO) write the two 4 digit ID: they are like 093a:2510

093a is the vendor ID

2510 is the product ID

# cd /etc/udev/rules.d/

# gedit 99-arduino.rules

// Add following lines in arduino rules file

for UNO

SUBSYSTEMS==”usb”, ATTRS{idProduct}==”XXXX”, ATTRS{idVendor}==”YYYY”, SYMLINK+=”ttyACM%n”

the others:

SUBSYSTEMS==”usb”, ATTRS{idProduct}==”XXXX”, ATTRS{idVendor}==”YYYY”, SYMLINK+=”ttyUSB%n”

# udevadm control –reload

reboot the system

SET THE PERMISSION

// Add user in Groups

# usermod -a -G uucp rsharma

# usermod -a -G lock rsharma

# usermod -a -G dialup rsharma

# ls -ld /run/lock

# cp /usr/lib/tmpfiles.d/legacy.conf /etc/tmpfiles.d/

# gedit /etc/tmpfiles.d/legacy.conf

change “d /run/lock 0775 root root – ” = to>>  “d /run/lock 0775 root lock – ”

# chmod o+rwx /run/lock

# ls -ld /var/lock

# chmod o+rwx /var/lock

Now Unplug and plug the Arduino device and Restart arduion IDE.

and you can see now Tools > Serial Port menu is activated.

just take a Quick test with your Device

// Copy this code in your IDE and upload to Micro controller

void setup() {
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
delay(1000);              // wait for a second
digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
delay(1000);              // wait for a second
}

Houdini in VFX Pipeline – Introduction Houdini User Interface

Houdini in VFX Pipeline  – Introduction Houdini User Interface

 

Setup PyQt4 in Houdini 13 for GUI Development

In this post we start PyQt user interface widget toolkit to create a custom user interface inside Houdini.
Houdini does not distribute PyQt4, so if it is not installed you need to install it to your Python distribution.

Lets See How to install and setup Qt and PyQt4 in Linux Centos.

Check Houdini Python Paths
Run in your Terminal- env | grep houdini

Now Understand about python versions-
Centos 6.5 ship with python 2.6
and houdini 13 ship with python 2.6 and python 2.7
so if you have working python version installed in computer than houdini takes system python version.
else houdini will use HFS python versions.

to use Houdini Python versions
You can set HOUDINI_USE_HFS_PYTHON to 1 in houdini environment.
open file /home/rajiv/houdini13.0/houdini.env
add following line:
HOUDINI_USE_HFS_PYTHON = 1

Now you can see python2.7.5 in python shell of houdini.
but no PyQt4 modules for houdini.

Python 2.7.5 (default, Oct 24 2013, 12:22:56)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2
Houdini 13.0.481 hou module imported.
Type “help”, “copyright”, “credits” or “license” for more information.
>>> import PyQt4
Traceback (most recent call last):
File “<console>”, line 1, in <module>
ImportError: No module named PyQt4
>>>

if in your system have python 2.7 with PyQt4 installed.
than you can add PyQt4 path (/usr/local/lib/python2.7/site_packages) in houdini sys.path
you may get following Error
ImportError: /usr/local/lib/python2.7/site-packages/PyQt4/_qt.so: undefined symbol: PyUnicodeUCS2_AsLatin1String

To Fix This Issue you should recompile PyQt against Hython (Houdini Python)

The Process of Compile PyQt for Houdini 13 on Centos 6.5

## Create Folder Structure
mkdir /tmp/Houdini_PyQt
mkdir -p /tmp/Houdini_PyQt/{bin,include,include/python2.7,lib,lib/python2.7,plugins,share,share/sip}

## Install QT
cd /tmp
wget http://download.qt-project.org/official_releases/qt/4.8/4.8.6/qt-everywhere-opensource-src-4.8.6.tar.gz
tar xvf qt-everywhere-opensource-src-4.8.6.tar.gz
cd qt-everywhere-opensource-src-4.8.6
./configure
make
make install
PATH=/usr/local/Trolltech/Qt-4.8.6/bin:$PATH
export PATH

## Install SIP
cd /tmp
wget http://sourceforge.net/projects/pyqt/files/sip/sip-4.16.2/sip-4.16.2.tar.gz
tar xvf sip-4.16.2.tar.gz
cd sip-4.16.2
hython configure.py –bindir=/tmp/Houdini_PyQt/bin –destdir=/tmp/Houdini_PyQt/lib/python2.7 –incdir=/tmp/Houdini_PyQt/include/python2.7 –sipdir=/tmp/Houdini_PyQt/share/sip
make
make install

## Install PyQt4
cd /tmp
wget http://sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.11.1/PyQt-x11-gpl-4.11.1.tar.gz
tar xvf PyQt-x11-gpl-4.11.1.tar.gz
cd PyQt-x11-gpl-4.11.1
## edit the configure.py and add the python command:
## sys.path.append(‘/tmp/Houdini_PyQt/lib/python2.7’) just before the line import sipconfig
hython configure.py –bindir=/tmp/Houdini_PyQt/bin –destdir=/tmp/Houdini_PyQt/lib/python2.7 –plugin-destdir=/tmp/Houdini_PyQt/plugins –sipdir=/tmp/Houdini_PyQt/share/sip –assume-shared
make
make install

 

Now copy /tmp/Houdini_PyQt folder to common location and add “Houdini_PyQt/lib/python2.7” in sys.path and add in PYTHONPATH

To Test PyQt4 in Houdini go to shelh and create new tool and in scripts window copy following code:

#================================================================================================================================================================================#

“””
This Python Script will display Python and PyQt Version Installed in Houdini.
“””
import sys
path = ‘/Houdini_PyQt/lib/python2.7’ # Add Houdini PyQt path here
if not path in sys.path:
sys.path.append(path)

import getpass
import PyQt4
import PyQt4.pyqtconfig
from PyQt4 import QtGui

PYQTVERSION = PyQt4.pyqtconfig.Configuration().pyqt_version_str
USER = getpass.getuser()
PYTHONVERSION = sys.version

app = QtGui.QApplication(sys.argv)
QtGui.QMessageBox.information(None, ‘PyQt Information’, ‘Hello %s\nyour python version is %s\n\nyour PyQt version is %s’% (USER,PYTHONVERSION,PYQTVERSION))

#================================================================================================================================================================================#

Now you are ready to drive with PyQt Gui Framework inside Houdini

CinePaint: Open source deep paint software on linux centos

CinePaint: Open source deep paint software
http://www.cinepaint.org/

Top Reasons to Use CinePaint

Support for 8-bit, 16-bit and 32-bit color channels of deep paint.

High fidelity image file types such as DPX, OpenEXR and 16-bit TIFF. These files can’t be opened in ordinary 8-bit image applications without crushing them.

High Dynamic Range. HDR images can go brighter than white. Ordinary images can’t be brighter than a white sheet of paper (0=black, 1.0=white).

Gallery-quality printing. B&W photographs have only one color channel and degrade quickly when manipulated as 8-bit images.CinePaint has higher fidelity and offers a 16-bit printing path to the print-head using GutenPrint.

Color Management System. CinePaint uses LittleCMS.

Flipbook. Movie playback of short sequences of images in RAM.

Innovation. CinePaint offers features that go beyond ordinary painting tools.

It’s used to make feature films at major studios.

Open Source. With various OSS licenses, because it uses code from various sources, including GPL, LGPL, BSD, and MPL.

Free.

Friendly professional developers. Polite discussion forums.

Being a CinePaint developer can be a good career move. CinePaint developers have gotten jobs at companies such as DreamWorks Animation,Sony Pictures Imageworks, and Apple.

Install cinepaint on Centos
Build and Install from source tarball

yum install lcms-devel libtiff-devel libpng-devel libjpeg-devel openexr-devel fltk-devel gutenprint-devel libXmu-devel

download latest version of Cinepaint from
http://sourceforge.net/projects/cinepaint/files/CinePaint/

#### Extract file
tar xvfz cinepaint.X.X.tgz
cd cinepaint

./configure
make
make install

### to start Cinepaint

cinepaint

you may get following message:
cinepaint: error while loading shared libraries: libcinepaint.so.1:
cannot open shared object file: No such file or directory

You need to run ldconfig after the install so that the
system can find the new libraries.

Just open a terminal and run:

ldconfig

Install and configure TACTIC 4.0 on CentOS 7

Get started with the world’s most powerful open source asset management tool: TACTIC

download from : http://community.southpawtech.com/downloads
Enterprise version (Latest TACTIC development release) 4.0.0.rc02
and
download TACTIC EPL License

Requirements:-
TACTIC requires the following software to be installed:

• Apache HTTP server 2.2
• Postgres Database Server 8.4 or higher
• Python 2.6 or 2.7 with the following Python modules:
• Python Imaging Library 1.1.7
• Python lxml 2.3.5
• Pycrypto 2.3
• Psycopg2 2.4.6

Lets Start Install and configure TACTIC 4.0.0.rc02 on CentOS 6.4 /RHEL

Disabling Security for Testing
For the sake of getting Tactic up quickly without a large amount of fuss, it is prudent to disable firewalling and SELinux. This is by no means an endorsement to run your server without these services. Once you have Tactic up and running we encourage you to read the section <TACTIC SECURITY>.
CentOS 6.4 uses the iptables service as a firewall. To disable this temporarily you can issue the following commands as root.
/etc/init.d/iptables save
/etc/init.d/iptables stop
This will disable the firewall for the currently running CentOS session. Should you wish these settings to persist across reboots. You can issue the following command as root.
/sbin/chkconfig iptables off
To disable SELinux, edit the file /etc/selinux/config as root with your favourite editor and set the SELINUX variable to ‘disabled’.
SELINUX=disabled
Getting this setting to take effect requires a reboot.

• Installing Apache HTTP server

yum install httpd
/etc/init.d/httpd start
/sbin/chkconfig httpd on

• Installing Postgres Database Server

rpm -qva | grep -i postgres

• Remove existing Postgres

rpm -e <package_name>

gedit /etc/yum.repos.d/CentOS-Base.repo
include the line under both the [base] section and the [updates] section of the file.
exclude=postgresql*

rpm -Uvh http://yum.postgresql.org/9.2/redhat/rhel-6-x86_64/pgdg-centos92-9.2-6.noarch.rpm

yum install postgresql postgresql-server postgresql-contrib postgresql-devel
yum install postgresql*
yum install postgresql-libs
su – postgres -c /usr/pgsql-9.2/bin/initdb
service postgresql-9.2 initdb
service postgresql-9.2 start
/etc/init.d/postgresql-9.2 start

netstat -nutlap | grep post
chkconfig –levels 235 postgresql-9.2 on

 

• Install ImageMagick (Image Manipulation) Tool on RHEL/CentOS

You need to install the command line version of imagemagick.

The basic PIL module in python may not be able to process more complex image formats. Like some special png or 32 bit tiffs.

yum install ImageMagick

 

• Install Python2.7 in CentOS 6.4

yum groupinstall “Development tools”
yum install gcc zlib-devel libxslt-devel libxml2-devel
yum install zlib-devel
yum install bzip2-devel
yum install openssl-devel
yum install ncurses-devel
yum install python-devel

cd /opt
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
tar xf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure –prefix=/usr/local
make && make altinstall

export LD_LIBRARY_PATH=/usr/local/lib/python2.7

• Installing Python Modules

-Installing lxml 2.3.5
cd /tmp
wget http://lxml.de/files/lxml-2.3.5.tgz
tar -zxvf lxml-2.3.5.tgz
cd lxml-2.3.5
/usr/local/bin/python2.7 setup.py install

-Installing Python Imaging Library 1.1.7
cd /tmp
wget http://effbot.org/downloads/Imaging-1.1.7.tar.gz
tar -zxvf Imaging-1.1.7.tar.gz
cd Imaging-1.1.7
/usr/local/bin/python2.7 setup.py install

-Installing Pycrypto 2.3
cd /tmp
wget http://pypi.python.org/packages/source/p/pycrypto/pycrypto-2.3.tar.gz
tar -zxvf pycrypto-2.3.tar.gz
cd pycrypto-2.3
/usr/local/bin/python2.7 setup.py install

-Installing Psycopg2 2.4.6
cd /tmp
wget http://initd.org/psycopg/tarballs/PSYCOPG-2-4/psycopg2-2.4.6.tar.gz
tar -zxvf psycopg2-2.4.6.tar.gz
cd psycopg2-2.4.6

gedit /tmp/psycopg2-2.4.6/setup.cfg
edit the pg_config entry to match the following:
pg_config=/usr/pgsql-9.2/bin/pg_config

/usr/local/bin/python2.7 setup.py install

Test Every Module is working fine :-
/usr/local/bin/python2.7

import psycopg2
import Crypto
import lxml
import PIL

It should be like that
[root@elitebook rajiv]# /usr/local/bin/python2.7
Python 2.7.3 (default, Aug 15 2013, 23:59:03)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.
>>> import psycopg2
>>> import Crypto
>>> import lxml
>>> import PIL
>>>

• Installing Tactic 4.0.0.rc02

cd /tmp
unzip tactic-4.0.0.rc02.zip

Before we run the Tactic installer, we must further configure Postgres to ensure proper installation of Tactic.
Configuring Postgres

service postgresql-9.2 stop
mv /var/lib/pgsql/9.2/data/pg_hba.conf /var/lib/pgsql/9.2/data/pg_hba.conf.INSTALL
cp /tmp/tactic-4.0.0.rc02/src/install/postgresql/pg_hba.conf /var/lib/pgsql/9.2/data/pg_hba.conf
chown postgres:postgres /var/lib/pgsql/9.2/data/pg_hba.conf
service postgresql-9.2 start

psql -U postgres template1

This command should fire up a prompt like this:
template1=#
Type \q to exit

/usr/local/bin/python2.7 /tmp/tactic-4.0.0.rc02/src/install/install.py

The installer will ask you a number of questions. You should be prompted by the following:
Please enter the base path of the TACTIC installation:
(/home/apache) -> /opt/tactic

get httpd users
ps -ef | grep httpd

Please enter the user Apache Web Server is run under:
(apache) ->apache

• -Configuring Apache

Lastly Tactic requires us to install the custom Apache configuration file it has created during the installation process. As root issue the following commands:
cp /opt/tactic/tactic_data/config/tactic.conf /etc/httpd/conf.d

To test this we should first verify that /etc/httpd/conf.d is an included module path in the main Apache configuration file. As root issue the following command:
cat /etc/httpd/conf/httpd.conf | grep conf.d

If you receive the following as output we have installed the Tactic Apache configuration file correctly.
Include conf.d/*.conf

edit /var/www/html/index.html
Add only the following line:
<META http-equiv=”refresh” content=”0;URL=/tactic”>

Restart the Apache service to make sure the configuration hasn’t caused any problems
/etc/init.d/httpd restart

Lastly we need to ensure that the Apache server has loaded the modules needed for proxying and load balancing the Tactic service
/usr/sbin/httpd -t -D DUMP_MODULES

In the resulting output look for the following modules:
[root@elitebook rajiv]# /usr/sbin/httpd -t -D DUMP_MODULES

• – Add Python 2.7 in Tactic Configuration :-

gedit /opt/tactic/tactic_data/config/tactic-conf.xml
Find the following line:
<python>python</python>
And replace it with:
<python>/usr/local/bin/python2.7</python>

• – Add PYTHONPATH in Tactic

gedit /opt/tactic/tactic/src/install/service/tactic

Add these Lines:-

PYTHON=/usr/local/bin/python2.7
export PYTHON
LD_LIBRARY_PATH=/usr/local/lib/python2.7
export LD_LIBRARY_PATH

• Starting Tactic

su apache -s /bin/bash -c “/usr/local/bin/python2.7 /opt/tactic/tactic/src/bin/startup_dev.py”

You should now be able to navigate a web browser to
http://localhost/tactic/admin

TACTIC defines an administrative user by default. The login information is:
Username: admin, Password: (set it on your first login)

Seafile – File Syncing and Collaboration for Teams on Linux Centos 6.4 / RHEL

Seafile – File synchronization and collaboration for teams
If you are in a small team with a few people, you can create a group in Seafile and invite other team members. Team members can then maintain file libraries together. You may collaborate around the files online. With file synchronization, it’s also easy to work on a set of files together.

Download
It’s Open Source!Check Seafile at Github

• Private

  Deploy on your own servers, under your control. It’s open source. You can add features as you wish.

• Convenient

  You can download and upload files on the website. You can also sync files to your computers with Seafile client program.

• Reliable

  Seafile keeps every version of your files. You may restore a file to an older version, or restore a mistakenly deleted file.

• Secure

  You may encrypt a file library with a password. The password won’t be stored by the server. So even the server administrator cannot view your private data.

Seafile Professional Edition — A Comprehensive Collaboraton Platform

File Syncing and Sharing

Organize files into libraries. Each library can be shared between users and into groups. A library can also be selectively synced into any device.

Collaboration and Discussion

Edit and comment files online. Messaging, group discussion, activity notification and file versions make collaboration easy and reliable.

Tasks

It’s simple and efficient to maintain a to-do list and assign tasks online, with a plain text file or with the tasks module.

Tags and Searching

Tag files, tasks and messages, organizing items in your way. Searching makes it even easier to find items.

Seafile CLI client

Installation

1. Download the client

   wget http://seafile.googlecode.com/files/seafile-cli_1.6.1_x86-64.tar.gz
   tar -xzf seafile-cli_1.6.1_x86-64.tar.gz

2. Initialise & daemonize the client

   cd seafile-cli_1.6.1
   # choose a folder where to store the seafile client settings e.g ~/.seafile-client
   mkdir ~/.seafile-client            # create the settings folder
   ./seaf-cli init -d ~/.seafile-client  # initialise seafile client with this folder
   ./seaf-cli start

3. Install seafile in your environment

   #link the full path of the exectuable
   ln -s `readlink -f seaf-cli` /usr/bin/

4. Download a library from a server
   1. retrieve the library id by browsing on the server -> it’s in the url after /repo/
   2. then

      seaf-cli download -l "the id of the library" -s  "the url + port of server" -d "the folder where the library folder will be downloaded" -u "username on server" [-p "password"]
      seaf-cli status  # check status of ongoing downloads
      # Name  Status  Progress
      # Apps    downloading     9984/10367, 9216.1KB/s

   Note: if you not supply the password parameter in the command, it will be asked later, which is more safe.

   Example:seaf-cli download -l 0536c006-8a43-449e-8718-39f12111620d -s http://cloud.seafile.com -d /tmp -u freeplant@test.com

5. Download a library from a server and sync with an existing folder.

   # This is the same as download : replace download by sync 
   seaf-cli sync -l "the id of the library" -s  "the url + port of server" -d "the folder where the library folder will be downloaded" -u "username on server" -p "password"

6. rejoice

Apache Subversion – version control system on centos 6.4 / RHEL

http://subversion.apache.org/

Subversion is an open source version control system.

Subversion exists to be universally recognized and adopted as an open-source, centralized version control system characterized by its reliability as a safe haven for valuable data; the simplicity of its model and usage; and its ability to support the needs of a wide variety of users and projects, from individuals to large-scale enterprise operations.

CACTI – Open source Network Monitor and web based Graphing tool for Linux CentOS 6.4

What is Cacti?

Cacti is a complete frontend to RRDTool, it stores all of the necessary information to create graphs and populate them with data in a MySQL database. The frontend is completely PHP driven. Along with being able to maintain Graphs, Data Sources, and Round Robin Archives in a database, cacti handles the data gathering. There is also SNMP support for those used to creating traffic graphs with MRTG.

Data Sources
To handle data gathering, you can feed cacti the paths to any external script/command along with any data that the user will need to “fill in”, cacti will then gather this data in a cron-job and populate a MySQL database/the round robin archives.

Data Sources can also be created, which correspond to actual data on the graph. For instance, if a user would want to graph the ping times to a host, you could create a data source utilizing a script that pings a host and returns it’s value in milliseconds. After defining options for RRDTool such as how to store the data you will be able to define any additional information that the data input source requires, such as a host to ping in this case. Once a data source is created, it is automatically maintained at 5 minute intervals.

Graphs
Once one or more data sources are defined, an RRDTool graph can be created using the data. Cacti allows you to create almost any imaginable RRDTool graph using all of the standard RRDTool graph types and consolidation functions. A color selection area and automatic text padding function also aid in the creation of graphs to make the process easier.

Not only can you create RRDTool based graphs in cacti, but there are many ways to display them. Along with a standard “list view” and a “preview mode”, which resembles the RRDTool frontend 14all, there is a “tree view”, which allows you to put graphs onto a hierarchical tree for organizational purposes.

User Management
Due to the many functions of cacti, a user based management tool is built in so you can add users and give them rights to certain areas of cacti. This would allow someone to create some users that can change graph parameters, while others can only view graphs. Each user also maintains their own settings when it comes to viewing graphs.

Templating
Lastly, cacti is able to scale to a large number of data sources and graphs through the use of templates. This allows the creation of a single graph or data source template which defines any graph or data source associated with it. Host templates enable you to define the capabilities of a host so cacti can poll it for information upon the addition of a new host.

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you’re doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.

Silicon Integrated Systems SIS5595… No
VIA VT82C686 Integrated Sensors… No
VIA VT8231 Integrated Sensors… No
AMD K8 thermal sensors… No
AMD Family 11h thermal sensors… No
Intel digital thermal sensor… Success!
(driver `coretemp’)
Intel AMB FB-DIMM thermal sensor… No
VIA C7 thermal and voltage sensors… No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): YES
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor’… No
Trying family `SMSC’… Yes
Found unknown chip with ID 0x0701
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor’… No
Trying family `SMSC’… Yes
Found unknown non-standard chip with ID 0x7a

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES
Probing for `National Semiconductor LM78′ at 0x290… No
Probing for `National Semiconductor LM79′ at 0x290… No
Probing for `Winbond W83781D’ at 0x290… No
Probing for `Winbond W83782D’ at 0x290… No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): YES
Sorry, no supported PCI bus adapters found.

/opt/lampp/lampp start

http://localhost/

make sure Apache httpd service is off (otherwide xampp will not start)
service httpd stop

if phpmyadmin is not open

Edit /opt/lampp/etc/extra/httpd-xampp.conf
and adding Require all granted line at bottom of block <Directory “/opt/lampp/phpmyadmin”> to have the following code:
<Directory “/opt/lampp/phpmyadmin”>
AllowOverride AuthConfig Limit
Order allow,deny
Allow from all

xvidcap 1.1.7 – Camtasia alternative in Linux Centos 6.4

xvidcap is a screencast – Screen recording application for Linux.

It allows you to capture either parts of the full screen of your Linux desktop.

This makes it an ideal tool for making either demonstrations of software – such as tutorials or for documenting installation of different software packages.

The screen capture is actually done by saving each frame as an individual image – this is then sent through a transcoder which produces a complete MPEG video file.

A small tool to capture things going on on an X-Windows display to either individual frames or an MPEG video similar to tools such as Lotus ScreenCam or.

 

download link http://sourceforge.net/projects/xvidcap/files/

extract xvidcap-1.1.7.tar.gz

Open terminal:-

Houdini on Linux

Houdini the First Major 3D Animation Package On Linux

Linux is better in a larger studio environment, and is around 10-15% faster on the same hardware as Windows.

HDK a lot easier on Linux as well as you can use the free compiler. On windows Visual Studio is the only way and you can’t compile without the full version for 64 bit.

On linux you can automate tasks a lot easier with shell scripts/python. This is more the stuff you do next to h Houdini like batch renaming files, triggering pre and post render scripts, rendering  files.

Of course on windows you can buy (or program) little programs that do it for you as well, but I find you have much more flexibility with Linux.

Also.. most bigger studios are on linux, so you might as well learn it.

Advantages of Linux in VFX Pipeline

Advantages of Linux in VFX Pipeline
Low cost: You don’t need to spend time and money to obtain licenses since Linux and much of its software come with the GNU General Public License. You can
start to work immediately without worrying that your software may stop working anytime because the free trial version expires. Additionally, there are large repositories from which you can freely download high quality software for almost any task you can think of.
The most obvious advantage of using Linux is the fact that it is free to obtain, while Microsoft products are available for a hefty and sometimes recurring fee. Microsoft licenses typically are only allowed to be installed on a single computer, whereas a Linux distribution can be installed on any number of computers, without paying a single dime.
Stability: Linux doesn’t need to be rebooted periodically to maintain performance levels. It doesn’t freeze up or slow down over time due to memory leaks and such. Continuous up-times of hundreds of days (up to a year or more) are not uncommon.

Performance: Linux provides persistent high performance on workstations and on networks. It can handle unusually large numbers of users simultaneously, and can make old computers sufficiently responsive to be useful again.
Linux is perfect for those old computers with barely any processing power or memory you have sitting in your garage or basement collecting dust. Install Linux and use it as a firewall, a file server, or a backup server. There are endless possibilities. Old 386 or 486 computers with barely any RAM run Linux without any issue

Network friendliness: Linux was developed by a group of programmers over the Internet and has therefore strong support for network functionality; client and server systems can be easily set up on any computer running Linux. It can perform tasks such as network backups faster and more reliably than alternative systems.

Flexibility: Linux can be used for high performance server applications, desktop applications, and embedded systems. You can save disk space by only installing the components needed for a particular use. You can restrict the use of specific computers by installing for example only selected office applications instead of the whole suite.

Compatibility: It runs all common Unix software packages and can process all common file formats.

Choice: The large number of Linux distributions gives you a choice. Each distribution is developed and supported by a different organization. You can pick the one you like best; the core functionalities are the same; most software runs on most distributions.

Fast and easy installation: Most Linux distributions come with user-friendly installation and setup programs. Popular Linux distributions come with tools that make installation of additional software very user friendly as well.

Full use of hard disk: Linux continues work well even when the hard disk is almost full.

Multitasking: Linux is designed to do many things at the same time; e.g., a large printing job in the background won’t slow down your other work.

Security: Linux is one of the most secure operating systems. “Walls” and flexible file access permission systems prevent access by unwanted visitors or viruses. Linux users have to option to select and safely download software, free of charge, from online repositories containing thousands of high quality packages. No purchase transactions requiring credit card numbers or other sensitive personal information are necessary.
In line with the costs, the security aspect of Linux is much stronger than that of Windows. Why should you have to spend extra money for virus protection software? The Linux operating system has been around since the early nineties and has managed to stay secure in the realm of widespread viruses, spyware and adware for all these years. Sure, the argument of the Linux desktop not being as widely used is a factor as to why there are no viruses. My rebuttle is that the Linux operating system is open source and if there were a widespread Linux virus released today, there would be hundreds of patches released tomorrow, either by ordinary people that use the operating system or by the distribution maintainers. We wouldn’t need to wait for a patch from a single company like we do with Windows.

Open Source: If you develop software that requires knowledge or modification of the operating system code, Linux’s source code is at your fingertips. Most Linux applications are Open Source as well.

Today the combination of inexpensive computers and free high-quality Linux operating systems and software provide incredibly low-cost solutions for both basic home office use and high-performance business and science applications. The available choices of Linux distributions and Linux software may be overwhelming at first, but if you know where to look, it shouldn’t take long for you to find good online guidance.
Disadvantages of Linux
Learning curve

I won’t lie to you; Linux is going to take some time to learn. I know that our society likes to be instantly gratified. Learning Linux is definitely worth your time, but to really master it, you will need to spend some good time in front of your machine tinkering with things. Don’t expect to be an expert after reading something like “Linux for Dummies”. If you are contemplating this for your company, you will need to budget some money for training and learning time.

More technical ability needed

You will want to make sure that you train someone in Linux really well. Alternately, you could hire someone who has experience with Linux. A good Linux administrator needs to be on hand as you start to migrate your systems over. This is a disadvantage financially, at least in the beginning. You may find over time, however, that you only need a temporary administrator to handle the routine tasks.

Not all hardware compatible

Some of the latest and greatest hardware that is being produced is not compatible with Linux. At least, not yet. The people that contribute program code and drivers to the Linux kernel are great at including support fairly quickly. Until that time, not everything you buy for hardware in your system may work. I’ve had to rely on third-party drivers and other means to make hardware like a new Ethernet card work. Eventually, the support will be built in. One thing you can do is before your purchase, ask if the hardware vendor has support for Linux. Some manufacturers do write their own Linux drivers and distribute them with your purchase, making it very easy to integrate with your existing system.

 

Exchange data between Houdini and Maya

option 01

http://code.google.com/p/alembic/wiki/GettingAlembic

Alembic is:

For computer graphics professionals working with large, complex scenes;

Who need to quickly, reliably transfer CG assets between heterogeneous software tools in order to make use of the widest range of available functionality;

Alembic is an Open, Portable, Computer Graphics Storage Format;

That is able to accurately store the full range of existing CG primitives, is open and easily extensible for custom data needs, and is fully supported in all the major CG animation, rendering, and simulation tools;

Unlike FBX, which is not extensible or open, or COLLADA, which is unable to store large assets, or custom solutions using GTO, which are non-standardized and require too much implementation-specific knowledge.

if you want a really smooth translation, get Maya 2013, it has alembic export, then get Houdini 12, it has alembic import, export the whole scene to alembic and you will have the camera too in one pass, works painlessly.

Shaders cannot be exported, although fbx imports with some shaders, but that one in Houdini is not good for serious shading.

Alembic doesn’t support shaders.

workflows to send stuff to Maya for rendering from Houdini. The best way to do that is with Alembic but the problem with that is you need to have all geometry that’s going to be exported be visible at the first frame.

OBJ sequences is the option, which is kind of lame since it just static geometry across frames but it works for things like newly-spawning geometry.

option 02

Filmbox FBX

Houdini understand FBX format. you can transfer dynamics from Houdini to Maya.

You should use the fbx exporter from maya, but there are some rules to be followed:

1. use maya’s geometry cache to generate a vertex cache.
2. in geo cache’s option check double precision
3. now the tricky part, if you have any history on the polygonal surface node, fbx export will drag it with export, so the best way is to duplicate your caracter geometry(only that) with shift+d, and import the geo cache onto that, so you will end up with a clean geometry and a cache file.
4. in fbx export window you have to uncheck smoothing groups under geometry
5. also here you have to check animation and check geometry cache file and choose a historySwitchSet
6. hit export (of course give an fbx filename), and if you choose a location there should be an fbx file exported and a folder beside it which contains the cache

7. in houdini choose File->Import->Filmbox FBX..
8. in the window choose your fbx file, uncheck everything except geometry and animation
9. choose unlock geometry and deformation
10. choose import directly into /obj network
11. houdini will import your model and assign the vertex cache via CHOPs

So animate in maya then export the clean model with vertex cache via fbx and import

Option 03

OBJ Export

http://www.creativecrash.com/maya/downloads/scripts-plugins/utility-external/export/c/obj-sequence-exporter

export as an obj sequence and use a file node to read it in.

PyMEL for Maya

 

PyMEL makes python scripting in Maya work the way it should. Maya’s command module is a direct translation of MEL commands into python functions. The result is a very awkward and unpythonic syntax which does not take advantage of python’s strengths – particularly, a flexible, object-oriented design. PyMEL builds on the cmds module by organizing many of its commands into a class hierarchy, and by customizing them to operate in a more succinct and intuitive way.

Maya 2012 x64 installation in CentOS 6.3 / CentOS 7

Maya 2012 x64 installation in CentOS 6.3  / CentOS 7

same installation process work for Maya 2015 in CentOS 7
Step01
First, install all these is needed for CentOS, do this before the installer
(you can also do this after Maya installation, but these are required to start Maya)

– Go to terminal and paste these commands:-

yum install mesa-libGLw
yum install csh
yum install libXp libXp-devel
yum install gamin audiofile audiofile-devel e2fsprogs-libs
yum install tcsh
yum install xorg-x11-fonts-ISO8859-1-100dpi
yum install xorg-x11-fonts-ISO8859-1-75dpi
yum install liberation-mono-fonts liberation-fonts-common liberation-sans-fonts liberation-serif-fonts

Step02
Go to Maya setup files  folder (where all RPM files are contained)
(before start installation – go to maya setup folders and find “setup” file,  right click and make permissions – allow executive file must checked on)
enter in administrator mode:-

su –
cd /home/rajiv/linux/maya2012
./setup

enter serial number etc.

////maybe try to chmod the .bin files
cd /usr/autodesk/maya2012-x64/bin
chmod 777 maya
chmod 777 maya2012

maya
or
./maya
to launch

Step03 (TroubleShoot Maya 2012 Issues in Linux)

//if you get…..error while loading shared libraries: libXp.so.6: cannot open shared object file: No such file or directory
yum install libXp

problems with middle mouse button? (when you try and pan with middle mouse?)
(Maya) window->settingAndPreferences>preferences->interface
you’ll see an option to enable/disable the mouse scroll wheel.

//problems with the alt key?  (Maya Viewport is not rotating)
go to – (CentOS)system>prefs>windows too for alt key behaviour
make it “SuperUser”

”
”
problems with fonts
system>administration>add remove programs
search for these packages
xorg-x11-fonts-ISO8859-1
install them all

there will be problems with the hotkeys and shortcuts (see the apple keyboard section below)

//if there is beef with sound files
yum install audiofile-devel
// and if that doesnt work maybe?
ln -s /usr/lib/libaudiofile.so.0 /usr/lib/libaudiofile.so

_______to make a launch icon
_______copy this command into the ‘command’ part of the preferences for the icon
/usr/autodesk/maya2012-x64/bin/maya

CentOS for Animation and VFX Pipeline

CentOS for Animation and VFX Pipeline.

Hi Friends,
When we talk about Linux Distributions, i personally like Linux Mint 13.
Since i installed Linux Mint in my HP Elitebook Workstation, i found every thing is running in my laptop 3 times faster than window7.
most of the time i am using my Elitebook for Houdini and Realflow simulations and its work great.
But Maya is very unstable and not working fine in Linux Mint.
Because i have done installation of maya by recompiling RPM Files to DEB files.

then i decide to switch to other Linux Distro.

After lots of Google search and compare all Linux os I found CentOS will be the better Option for Animation and VFX Studios Pipeline.

CentOS is reliable and stable linux Operating system .
This Linux Distribution is very popular for servers and workstations.
centOS is Based on RHEL (Red Hat Enterprise)
easyly install RPM files.
there are lots of Animation and VFX studios using centOS in there entire facility include Dr D studios, Sydney Australia (I worked there on Happy Feet 2 movie).
Maya, Houdini, realflow Nuke and Naiad is working fine.
I Build Render Farm application for Linux using codes and lib of ArsenalSuite
,Asset Management softwares , Production Tracking Applications, Pipeline tools for Houdini, Maya, Nuke.
now every thing is working fine, fast and stable.

Final Conclusion:-
Ubuntu Based Linux Mint is a great Desktop Linux Operating system.
all latest softwares come with installation DVD. and interface is friendly for windows users.
APT (Advance Pakaging Tool) is very good and fast.

CentOS is great for big organisations, companys. It is derived entirely from the Red Hat Enterprise Linux (RHEL) distribution. CentOS exists to provide a free enterprise class computing platform and strives to maintain 100% binary compatibility with its upstream source, Red Hat. CentOS stands for Community enterprise Operating System.
All major 3d Application Officially support Red Hat. and CenOS is based on same.

ArsenalSuite – Render farm and cluster management tools.

     Arsenalsuite – Render farm and cluster management tools.

Hi,
I am doing some R&D on building Render Farm software for Windows and Linux OS.

I am using CentOS 6.3 and Window 7  both are 64bit OS.

I found ArsenalSuit is good and The best thing is that you can download the source code and adapt it to your company requirements.
Previously, I used this software in Dr D studios for Happy Feet 2 movie.
But The problem with Arsenal is there is no complete package for installation. you need to build it from scratch.

The very first impression is that you don’t know what you need from the download site. So I downloaded all windows packages.

Okay, I tried to get an overview of the project. The website says its still a beta in-progress project and indeed it feels exactly like that. There is no simple install package, there are some information about building the tools from scratch. But you will need some software building experience if you dare to use this project. And you will have to spend a lot of time to dig into the deeps of the project, build all tools and setup correctly. To be honest, I gave up after some time, simply because I did not find out a clean description how to start the arsenal suite on windows. Maybe this will change in the future because the feature list and screenshots look really good for a free system. For example, it seems you need to setup a postgresql database with some scripts, but these scripts are only available in the source code. To build the source code you will need Qt installed and other prerequisites.

About ArsenalSuite
Home Page – http://code.google.com/p/arsenalsuite/
Originally developed by Blur Studio, Arsenal was a replacement for 3dsmax’s BackBurner. It’s now a robust cross platform render management platform supporting many renderers, including 3dsmax, Maya, Houdini, 3delight, XSI, Nuke, Fusion, Shake and After Effects.
The core is written in C++ using Qt, and extensive python bindings using sip/PyQt provide the ability to customize and extend nearly every component. There are GUI tools to manage the queue, custom submitters for some packages, and a generic Python API for others.
A Google Group for discussion exists here: https://groups.google.com/group/arsenalsuite

Getting Started – Autodesk Maya Python API

1. Not Fully Grasping the Maya Architecture and How the Python API Leverages It
   If you don’t completely understanding the Maya architecture, command engine and the Dependency Graph, you will run into trouble as your tools get more complex. Take the time to learn these components as they are very different than any other animation product. Because of this complexity, it makes Maya more flexible and powerful than any other product. Check out the free Maya Python API webcast recording located here (www.autodesk.com/developmaya)

2. Trying to live in a Bubble and Teach Yourself Everything
   There is no possible way to memorize or learn every single Maya API class, so don’t be shy to use the resources available. As they say “Be Resourceful” and learn from others successes, mistakes and questions. Maya has been around for over ten years, and there is lots of API information out there (www.autodesk.com/developmaya). Also, you can check out the new book “Maya Python for Games and Film: A Complete Reference for Maya Python and the Maya Python API” by Adam Mechtley and Ryan Trowbridge.

3.    The Reference Documentation is written for C++, but you are Using Python
If you do not know C++, at first glance the reference documentation will be very confusing!  But don’t worry; just put your eye blinders on to certain things when reading it. Because Python is a more simplified language than C++ (but none the less powerful), there are certain components in the documentation you can ignore. For example the class MString and MStringArray are not available in Python and instead you will work with strings as they are in native Python. Another example is that there is no MStatus class in Python and instead you will use standard Python error checking (try, except, catch). Try to think of this as having a mini translator going on in your brain, you see MStatus, so you just ignore it!

4.       The Reference Documentation is written for C++, but you are Using Python

Another example is that there is no MStatus class in Python and instead you will use standard Python error checking (try, except, catch). Try to think of this as having a mini translator going on in your brain, you see MStatus, so you just ignore it!

5.       Knowing when and how to Use MScriptUtil Class
Many of the API methods in Maya require that one or more of their parameters be passed as pointers or references (return values can be pointers or references as well). Because Python does not have the concept of references or pointers, you will need the utility class called MScriptUtil for working with those pointers and references in Python. MScriptUtil bridges this gap between Python and its underlying C++ API. When you see the characters * or & in the documentation for simple data types like integers and floats, think MScriptUtil!

6.  Your Python API Code is not Working, and you cannot find the Problem
When working with the Python API, like all humans, you will have errors or code you want to debug; but how the heck do you debug it? Unfortunately, there are no out-of-the-box tools in Maya, but there are some good solutions available. Cyrille Fauvel from Autodesk has integrated a Maya Python debugger into the Eclipse IDE. The details are available on Autodesk.com, at the Maya Developer Center page. Dean Edmonds also from Autodesk has integrated the PDB debugger into the Script Editor within Maya by overriding the stdin and stout functions. Also, if you Google “Python in Maya” group you will see other solutions

7.   Working with Multiple Versions of Maya Equals Multiple Versions of Python
If you are working on multiple versions of Maya, then you need to keep in mind that you will need to have multiple version of Python. Also if you are using PyQt, multiple versions of PyQt will need to be installed on your computer. As nice as it would be to use the same version of Python and PyQt for every version of Maya, it’s just not realistic as things are always improving in the Python and PyQt releases. Keep yourself educated in the Maya documentation for the versions that are used in each major release, and on which platform.

8.  Awareness of Potential Python API Performance Penalties
In certain situations when computation involves complex or many API calls, the Python API may take a performance penalty compared to the C++ API. This is because the Python API sits on top of the C++ API. This results in an extra level of conversion through C++ and as well as Python is an interpreted language which is slower by nature. For example if you are thinking of doing a Python API shader, C++ will be the better choice, but for most other tasks Python is perfect!

9.  Must use Autodesk Specific Version of Qt for Building PyQt
Building PyQt to work with Maya is a three step process. First you need to compile Qt using the Autodesk’s Modified Qt Source Code (new for 2012) that is located on the Autodesk.com site. Then you need to compile SIP (generates Python bindings for C++) against your built Qt libraries. Last, you need to compile PyQt against your built SIP libraries. Check the website for the correct versions or you could have some difficulties down the road in your tools

10. Python Plug-in Disclosure
You cannot hide your Python API code from users! If you’re a games developer looking to create Python plug-ins in-house and not worried about protecting your code, then feel free to code away. But it you want to protect, or commercialize and sell your hard work, you should consider using C++ to create your plug-ins.

11. Not Understanding the Difference between Python Script and Python API
Maya has four programming interfaces, two of which are using the Python language. It’s important to know the distinction between the terminology of Python Script and the Python API, because they each access different functionality within Maya (with very little overlap). The other two interfaces are Maya Embedded Language (MEL) and the C++ API

Linux vs Windows ..? for Animation and VFX Work

Linux vs Windows ..? for Animation and VFX Work

I am Using  Window 7 at Office and Linux Mint 13 at Home.
Windows is more common, and easier to set up for a single user.
Linux is better in a larger studio environment, and is around 10-20% faster on the same hardware as Windows.
I found Houdini, Maya, and realflow is playing a lot faster In Linux compare to windows. this result is based on my Heavy Simulations and Rendering task.
Maya 2012 64bit is having some issues bugs (Because, I am using debian based Linux Operating system and Maya Native design for Red Hat OS  RPM.)

I Found network speed in Linux is 10 to 25 % fast that windows (this is based on Realflow simulation data (Grid Domain Particles, Meshing) , Maya Fluids and N Particles Cache,  Read and write on network disk)

Pipeline tools design and intigration in production is better in Linux compare to window 7.
compiling extra plugins in the HDK a lot easier on linux as well as you can use the free compiler. On windows Visual Studio is the only way and you can’t compile without the full version for 64 bit.
On linux you can automate tasks a lot easier with shell scripts/python. This is more the stuff you do next to houdini, like batch renaming files, triggering pre and post render scripts, rendering  files.
Of course on windows you can buy (or program) little programs that do it for you as well, but I find you have much more flexibility with linux.
Also.. most bigger studios are on linux.

Linux is Free for any use.  and  for windows you have to pay 12,000 INR

Autodesk Maya File references between Linux and Windows

Autodesk Maya File references between Linux and Windows

Issue : I have created a Scene file in windows and reference characters and assets from Z:/ Drive (production Drive).

these Maya Scene files i am not able to open in Linux Workstations (Because linux doesn’t have Z:/ Drive )

For Example:

Z:/ is root of production drive in Windows

(Z:/Assets/Characters/Scooby/ , Z:/Production/Scenes/Seq05/Sh001/FX/ , Z:/Assets/Textures/Hdri/ )

/project is root of Production drive in Linux

Same Folder structure in Linux After Mount by SAMBA window share looks like that :-

(/project/assets/Characters/Scooby , /project/Production/Scenes/Seq05/Sh001/FX/ , /project/Assets/Textures/Hdri/ )

to resolve the issue of missing path of Reference maya files

Add these two line in userSetup.mel (contained in Maya Scripts folder)

dirmap -en true;

dirmap -m “Z:/” “/project”;

restart maya and Enjoy 🙂

installation of Houdini in Linux Mint

How to install Houdini in Linux ..?

Open a terminal
Change to the root user if installing Houdini outside of your home directory

If you are installing the License Server, you must install the software as the root user because the License Server files are written to /usr/lib/sesi.
If you are not installing the License Server, the software can be installed as a non-root user

Unpack the downloaded archive

tar.gz archive (type: tar -xvzf file.tar.gz)

Example:
tar -xvzf houdini-10.0.249-linux_x86_64_gcc4.1.tar.gz
This should create a directory called houdini-10.0.249-linux_x86_64_gcc4.1/

7z archive (type: 7z x file.7z)

Example:
7z x houdini-10.0.249-linux_x86_64_gcc4.1.7z
This should create a directory called houdini-10.0.249-linux_x86_64_gcc4.1/

Run the houdini.install script:

cd houdini-10.0.249-linux_x86_64_gcc4.1/
./houdini.install

* You can also double click on the houdini.install file with your mouse. It will run the installer in a terminal.
Follow the instructions in the installer. The default installation wants to place the software in /opt/hfs10.0.249. If installing as a non-root user, you must change this default installation path. Example: /home/janedoe/hfs10.0.249
You should now be able to access Houdini in 2 ways:

Applications->Side Effects Software->Houdini 10.0.249
In a terminal(shell) type:

cd ; (Example: cd /opt/hfs10.0.249)
source houdini_setup;
type houdini (or hescape to start Escape) at the command prompt

The command “source houdini_setup” initializes the current shell’s environment to run Houdini. You may want to add the above line to your .login file. Refer to the contents of the houdini_setup script for more details.

VFX Pipeline in Linux Mint 13

Free Download Linux Mint DVD from :- http://www.linuxmint.com/download.php

this is great linux distro for VFX Pipeline.

 

Linux Mint, a distribution based on Ubuntu, was first launched in 2006 by Clement Lefebvre, a French-born IT specialist living in Ireland. Originally maintaining a Linux web site dedicated to providing help, tips and documentation to new Linux users, the author saw the potential of developing a Linux distribution that would address the many usability drawbacks associated with the generally more technical, mainstream products. After soliciting feedback from the visitors on his web site, he proceeded with building what many refer to today as an “improved Ubuntu” or “Ubuntu done right”.

But Linux Mint is not just an Ubuntu with a new set of applications and an updated desktop theme. Since its beginnings, the developers have been adding a variety of graphical “mint” tools for enhanced usability; this includes mintDesktop – a utility for configuring the desktop environment, mintMenu – a new and elegant menu structure for easier navigation, mintInstall – an easy-to-use software installer, and mintUpdate – a software updater, just to mention a few more prominent ones among several other tools and hundreds of additional improvements. The project also designs its own artwork, while its reputation for ease of use has been further enhanced by the inclusion of proprietary and patent-encumbered multimedia codecs that are often absent from larger distributions due to potential legal threats. However, one of the best features of Linux Mint is the fact that the developers listen to the users and are always fast in implementing good suggestions.

While Linux Mint is available as a free download, the project generates revenue from donations, advertising and professional support services. It doesn’t have a fixed release schedule or a list of planned features, but one can expect a new version of Linux Mint several weeks after each stable Ubuntu release. Besides the “main” edition which features the GNOME desktop, the project also builds a variety of semi-regular “community” editions with alternative desktops, such as KDE, Xfce and Fluxbox. However, these are often completed several months after the release of the “main” GNOME edition and may sometimes miss some of the “minty” tools and other features found in the project’s flagship product. A more recent addition to the Mint line-up is a “rolling-release” edition based on Debian’s testing branch. Linux Mint does not adhere to the principles of software freedom and it does not publish security advisories.

• Pros: Superb collection of “minty” tools developed in-house, hundreds of user-friendly enhancements, inclusion of multimedia codecs, open to users’ suggestions
• Cons: The alternative “community” editions don’t always include the latest features, the project does not issue security advisories
• Software package management: APT with mintInstall using DEB packages (compatible with Ubuntu repositories)
• Available editions: A “main” edition (with GNOME), a variety of “secondary” editions (with KDE, Xfce and Fluxbox), Linux Mint “Debian” edition (rolling-release with GNOME or Xfce)
