Ubuntu is composed of many software packages, the vast majority of which are distributed under a free software license. The only exceptions are some proprietary hardware drivers.The main license used is the GNU General Public License (GNU GPL) which, along with the GNU Lesser General Public License (GNU LGPL), explicitly declares that users are free to run, copy, distribute, study, change, develop and improve the software. On the other hand, there is also proprietary software available that can run on Ubuntu. Ubuntu focuses on usability, security and stability. The Ubiquity installer allows Ubuntu to be installed to the hard disk from within the Live CD environment, without the need for restarting the computer prior to installation. Ubuntu also emphasizes accessibility and internationalization to reach as many people as possible.

PRICE image filtering and manipulation for GNUstep: filters.

Sunday, February 22, 2015

PRICE was born to support my research in image processing. So I have decided to work on a usable application that can open several file formats and apply high quality filters and other enhancements to the image.


Make Grayscale.

Converts the image to greyscale, this calculates the luminosity of each pixel by averaging red, green and blue values.

Since currently many filters work on grayscale images only, this is useful.


Convolve 5x5.

The "small" convolution engine is now ready and functional. By entering a 5x5 matrix you can specify a FIR (Finite Impulse Response) filter that will be applied on the image. Since usually the dynamic range will exceed the available 8 bit range, you can either specify an offest and a scale (the over or undershooting will be clipped) or activate the autoscale algorithm.


Installing Pinta on Ubuntu.

Pinta can be installed on Linux, Mac or Windows. Due to this, there are multiple ways to install Pinta based on what you are using as your operating system.


This document will show you the multiple ways to install Pinta.

20 Ubuntu Derivatives You Should Know About

Whether you like Ubuntu or not, it is here to stay. Ubuntu has contributed a lot to the Linux community in sparking interest in new Linux users and opening the doors to “ease-of-use” Linux. Their Influence has spread throughout the Linux community sparking new distributions.

Here are 20 of them you should know about:


Link: http://www.linuxmint.com/

Linux Mint’s purpose is to produce an elegant, up to date and comfortable GNU/Linux desktop distribution.

Linux MintLinux Mint is one of the surprise packages of the past year. Originally launched as a variant of Ubuntu with integrated media codecs, it has now developed into one of the most user-friendly distributions on the market - complete with a custom desktop and menus, several unique configuration tools, a web-based package installation interface, and a number of different editions. Perhaps most importantly, this is one project where the developers and users are in constant interaction, resulting in dramatic, user-driven improvements with every new release. DistroWatch has spoken to the founder and lead developer of Linux Mint, Clement Lefebvre, about the history of the distribution.


Link: http://www.kubuntu.org/

KubuntuKubuntu is the KDE version of Ubuntu. This version comes packed with the KDE window manager instead of Gnome.

Kubuntu is a free, user-friendly operating system based on the K Desktop Environment and on the award winning Ubuntu operating system. With a biannual release cycle and at least 18 months of free security updates for each release, it is the secure, stable computing environment you’ve been waiting for. Take the tour or hear what our users have to say.

So basically if you like Ubuntu and prefer the KDE window manager you might want to install this instead of Ubuntu. It will save you the time of downloading and installing KDE and switching window managers.


Link: http://edubuntu.org/

Edubuntu’s objective is to create an integrated and usable experience for educational users by enhancing Ubuntu with educational applications, tools, content, and themes.

“Ubuntu” is an ancient African word, meaning “humanity to others”. Edubuntu seeks to bring the freedoms and spirit of Ubuntu to children, parents, students, teachers, and schools.


Link: http://www.xubuntu.org/

xubuntuXubuntu is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers. It contains all the applications you need - a web browser, document and spreadsheet editing software, instant messaging and much more.

If you like Ubuntu but prefer the XFCE window manager download Xubuntu and check it out.

GobuntuGobuntu is a GNU/Linux operating system, derived from Ubuntu, that endeavors to adhere to the Free Software Foundation’s four freedoms and intends to provide a base for other free software platforms to build upon with minimal modification required. It does this by only including open-source non-restricted software. This means there will be no firmware, drivers, applications, or content included in Gobuntu that does not include the full source or whose license does not provide the right to use, study, modify, and redistribute the body of work.

Gobuntu shares the same system requirements as Ubuntu. At present, this means Gobuntu is available for 32-bit and 64-Bit PC architectures and the install requires at least 4 GB of disk space.

Ubuntu Studio

MyPaint is a fast and easy open-source graphics application for digital painters: Introduction.

Monday, February 9, 2015

MyPaint is a fast and easy open-source graphics application for digital painters.


It lets you focus on the art instead of the program.


You work on your canvas with minimum distractions, bringing up the interface only when you need it.




This section is supposed to be a reference on what and how you can do things in MyPaint.


It does not aim to teach you how to paint.



PsychoPy Psychology Software in Python.

PsychoPy is an open source software package, written in Python programming language, for the generation of experiments for neuroscience and experimental psychology.


Unlike most packages it provides users with a choice of interface; generate experiments by writing Python scripts or through a graphical interface which will generate a script for them (or by a combination of the two).


Its platform independence is achieved through the use of the wxPython widget library for the application and OpenGL for graphics calls.


Because it’s open source, you can download it and modify the package if you don’t like it. And if you make changes that others might use then please consider giving them back to the community via the mailing list. PsychoPy has been written and provided to you absolutely for free. For it to get better it needs as much input from everyone as possible.


Ubuntu completes 9 Years.

Saturday, February 7, 2015

OMG Ubuntu released this beautiful infographic, which talks about the history of Ubuntu.


I have literally grown (yes, even my waist) as a person when working with Ubuntu.


I have been using Ubuntu since 2004, when I only used to flirt with Linux. What tickled me back then was the Ubuntu was afrikaans for freedom.


2006 was the first time when I stopped using Windows altogether and worked for 2 straight years on Dapper Drake.


Those were the days, when I was single, was in Hyderabad and spent consecutive new years eves drinking a single malt and installing a new version of Ubuntu.


As I look back and see how working on Ubuntu has impacted me, and my preferred style of working,


I only appreciate that this distro has made such a huge impact on personal computing, that its being used by non-techies to do day to day work.

Krusader is an advanced, twin-panel file-manager for KDE: Introduction.

Wednesday, February 4, 2015

Krusader is a simple, easy, powerful, twin-panel file manager (commander-style) for KDE and other *nix desktops, similar to Midnight Commander or Total Commander©. It provides all the file management features you could possibly want.


Krusader also includes extensive archive handling, mounted file system support, FTP, advanced search module, viewer/editor, directory synchronization, file content comparisons, powerful batch renaming and much, much more. Krusader supports archive formats: ace, arj, bzip2, deb, gzip, iso, lha, rar, rpm, tar, zip and 7-zip and handles other KIO Slaves such as smb:// or fish://.


Krusader is almost completely customizable and therefore very user-friendly.

Our aim is to give you a simple, intuitive tool that easily handles the most important tasks you perform on your computer each and every day: manage and process your files the way you want.


krusader logo


Whether you are a Linux® expert or a novice, Krusader makes routine file management tasks quick and accurate, allowing you to focus on the big picture, not command line syntax. This is especially helpful if you are new to xxNIX operating systems. To do just that, Krusader uses a good-looking GUI and supports drag and drop as well as MIME types, making it easy to use.


Krusader has many useful features. It is fast, and handles archives transparently. In addition, Krusader streamlines many complex file management tasks, reducing fatigue, errors, and distraction. Basically, Krusader provides all the helpful features you have come to expect from other quality file management tools like Midnight Commander and Total Commander©.


Krusader is designed to integrate seamlessly with the KDE Desktop, the desktop of choice for many programmers, network engineers, and other power users of Linux®. With Krusader even novice users can quickly access the power, convenience, and feature rich capabilities of the KDE Desktop. Krusader is a free open-source project, and it is released under the GNU General Public License (GPL), although the developers still retain the copyright for the project and its name, and manage the project's continuing evolution.


The Krusader Project mission is to create an "all-in-one" file manager, which will do all the ordinary things you would expect of it, and more. Since the principle behind Krusader is based on the Orthodox File Manager (OFM), dual-pane filemanagers (Midnight Commander, Norton Commander®, etc.), it is certain that Krusader is able to handle all the standard Copy, Move, Delete, etc. file operations.


From the start, virtual file systems became the main focus. Virtual file systems (VFS) are an abstracted layer over all kinds of archived information (ZIP files, FTP servers, TAR archives, NFS filesystems, SAMBA shares, ISO CD/DVD images, RPM catalogs, etc.), which allow the user to access all the information in these divergent types of file systems transparently - just like entering an ordinary sub-directory. Files can then be copied or moved around (except ISO, rpm, tar.gz) between these data sources/containers effortlessly. Krusader currently supports VFSs for all popular and some specialized types of archives (ace, arj, bzip2, gzip, iso, lha, rar, tar, zip and 7-zip), configuration packages (rpm, deb), and traditional remote file system types (FTP, NFS, Samba, FISH, SFTP).

Krusader screen shot

Krusader also includes a built-in Mount-Manager MountMan, which enables you to mount or unmount file systems of all types with a click of a mouse. The user is able to obtain usage and other property information easily, in a consistent and understandable format in seconds. Ease and consistency is the goal.


A Bookmark-Manager for local files/remote URLs and an Advanced Search module is also included to speed the locating of needed files. Krusader also allows the user to configure Toolbars in order to provide a wide variety of additional functionality, such as File Comparison (several user selectable methods available), Multiple File Rename, and standard Terminal windows.


Advanced users benefit greatly from being able to carry out clerical tasks effortlessly, without distraction from the real task at hand. Convenient shortcut keys enable the user to navigate directory trees with ease, create multiple tabbed directory views simultaneously, and access fully functional history lists. Due to efficient programming and low system overhead, Krusader is perhaps the most responsive all around system management tool used to access the full potential of a computer using KDE, or any other standards compliant X Window System® window manager. Although designed specifically for - and tightly integrated with - KDE, Krusader works equally well with GNOME, Enlightenment, Window Maker, IceWM, BlackBox, Wiamea, XFCE, etc., as long as the KDE libraries are installed.


New extensibility is provided by the flexible UserActions, a Krusader innovation that allows unlimited additional custom functionality to be added to suit the specific needs of users. We are planning to develop more modules in the near future, thereby enhancing Krusader. Information on what is proposed, approved, or remains to be completed can be found in the ToDo Forum.


No other program we know of, offers so many useful, easily accessible features in such an intuitive and simple format. Best of all, we listen, and implement good suggestions that are consonant with the Krusader Project's goal: making Krusader the very best File Manager available.

PhotoRec, Digital Picture and File Recovery.

Tuesday, October 28, 2014

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted.


PhotoRec is free - this open source multi-platform application is distributed under GNU General Public License (GPLV v2+). PhotoRec is a companion program to TestDisk, an application for recovering lost partitions on a wide variety of file systems and making non-bootable disks bootable again. You can download them from this link.


For more safety, PhotoRec uses read-only access to handle the drive or memory card you are about to recover lost data from. Important: As soon as a picture or file is accidentally deleted, or you discover any missing, do NOT save any more pictures or files to that memory device or hard disk drive; otherwise you may overwrite your lost data. This means that while using PhotoRec, you must not choose to write the recovered files to the same partition they were stored on.

    How to send SMS using Kontact.

    Create an account at smsjoker (or something similar). Prices are ok and writing SMS at your PC just rocks.


    Load script “smsjoker-script” from kde-apps.org. Open Konsole and with root permissions. Copy script to /usr/local/bin and make it executable:


    # cp smsjoker-script /usr/local/bin/
    # chmod a+x /usr/local/bin/smsjoker-script


    Call up program as the regular user once.


    $ smsjoker-script


    Now you will find a hidden file called “.smsjoker-script” in your home directory. Open this file with e.g. Kate and change the parameters OWN_NUMBER and PASSWORD. Use values you have used when creating your account.
