http://www.ubuntulinuxhelp.com/top-100-of-the-best-useful-opensource-applications/

 

The following is a list of about 100 of the best OpenSource Applications, that actually help make Linux more usable for people. It is my hope that this list shows potential Linux users that there really is a large, effective, productive and usable range of free, OpenSource applications. For existing Linux users (like myself), I think this will provide a great resource in finding applications that may better suit your needs, or just for fun! Needless to say, this is just some of the thousands of applications available! I develop web sites, so this list tends to focus on applications which support that type of work.

The majority of these applications can be installed by either apt-get or synaptic, however I’ve included the web site addresses of these applications so that you can obtain more information. I’ve tried many of these applications myself – and they are pretty good!

This list took a long time to put together and I tried to keep it in alphabetical order for you. – You might want to bookmark this and come back later. 
Enjoy!

GIMPshop:
(http://www.gimpshop.com/)

GIMPshop is a modification of the free/open source GNU Image Manipulation Program (GIMP), intended to replicate the feel of Adobe Photoshop. Its primary purpose is to make users of Photoshop feel comfortable using GIMP.

It shares all GIMP’s advantages, including the long feature list and customisability, while addressing some common criticisms regarding the program’s interface: GIMPshop modifies the menu structure to closely match Photoshop’s, adjusts the program’s terminology to match Adobe’s, and, in the Windows version, uses a plugin called ‘Deweirdifier’ to combine the application’s numerous windows in a similar manner to the MDI system used by most Windows graphics packages. While GIMPshop does not support Photoshop plugins, all GIMP’s own plugins, filters, brushes, etc. remain available.

Due to the changes to the interface, many Photoshop tutorials can be followed in GIMPshop unchanged, and most others can be adapted for GIMPshop users with minimal effort.

Pixelize works by splitting up the image you want rendered (or duplicated) into a grid of small rectangular areas. Each area is analyzed, and replaced with an image chosen from a large database of images.

Pixelize tries to pick images that best match each area.

Pixelize works best when it can choose images from a very large database of images. With about 1000 images, Pixelize can do a reasonable job.

Synfig:
(http://synfig.org/Main_Page & http://www.synfig.com/)

Synfig is a powerful, industrial-strength vector-based 2D animation software package, designed from the ground-up for producing feature-film quality animation with fewer people and resources. While there are many other programs currently on the market to aid with the efficient production of 2D animation, we are currently unaware of any other software that can do what our software can.

2D Animation has traditionally been very expensive because every frame must be drawn by hand. Even with today’s digital inking and painting software, the process still relies on individuals hand-drawing each frame. This laborious task is called “tweening”.

Our animation technology eliminates the task of manual tweening, producing smooth, fluid motion without the animator having to draw out each frame individually.

This allows you to produce 2D animation with fewer people while producing a product of a higher quality.

Xara Xtreme:

KPovModeler:
(http://www.kpovmodeler.org/)

KPovModeler is a modeling and composition program for creating POV-Ray(TM) scenes in KDE.

For most of the modelers, POV-Ray is nothing but a rendering engine and they bring a lot of limitations to the innate possibilities of POV-Ray scripted language. This is not the case for KPovModeler which allows you to use all the features of POV-Ray through the translation of POV-Ray language into a graphical tree.

Almost all options of POV-Ray’s script language can be used within KPovModeler. “Almost” because variables, loop instructions, macros and some operators can’t directly be, unfortunately. On the other hand, KPovModeler allows you to include a part of a script with the “Raw POV-Ray” tool; such a raw code will only be taken into account by POV-Ray during the rendering stage.

Among the features you can find:

Management of the scene through a graphical tree.
Object modification with control points in a graphical view or direct manipulation of object attributes in a dialog.
Nonblocking scene rendering with OpenGL as wire frame views.
Freely configurable view layout with dock widgets.
Copy/paste and drag/drop of (a subset of) povray(!) code into and out of the object tree.
Undo and redo.
Scene rendering and texture preview with povray inside the program.
Support for almost all povray objects.
Support for all textures.
Prototypes (declarations) and references.
All projection modes of the camera.

Rox-Filer:
(http://roscidus.com/desktop/ROX-Filer)

ROX is a desktop environment, like GNOME, KDE and XFCE. It is an attempt to bring some of the good features from RISC OS to Unix and Linux.
Traditionally, Unix users have always based their activities around the file system. Just about everything that’s anything appears as a file: regular files, hardware devices, and even processes on many systems (for example, inside the /proc filesystem on Linux).

However, recent desktop efforts (such as KDE and GNOME) seem to be following the Windows approach of trying to hide the filesystem and get users to do things via a Start-menu or similar. Modern desktop users, on Windows or Unix, often have no idea where their programs are installed, or even where their data files are saved. This leads to a feeling of not being in control, and a poor understanding of how the system works.

The ROX Desktop, however, is based around the file system. Its core component is ROX-Filer, a powerful graphical file manager which, in addition to being a popular filer in its own right, provides a couple of extra features which allow it to solve the above problems.

TrueCrypt:
(http://www.truecrypt.org/)

Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux.

Encryption is automatic, real-time (on-the-fly) and transparent.

Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:

1) Hidden volume (steganography – more information may be found here).

2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).

VNC:
(http://www.cl.cam.ac.uk/research/dtg/attarchive/vnc/index.html)

VNC stands for Virtual Network Computing. It is, in essence, a remote display system which allows you to view a computing ‘desktop’ environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures.

WINE:
(http://www.winehq.org/)

Wine is an Open Source implementation of the Windows API on top of X, OpenGL, and Unix.

Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code, however Wine can optionally use native Windows DLLs if they are available. Wine provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes, including Linux, FreeBSD, Mac OS X, and Solaris.

XFE:
(http://roland65.free.fr/xfe/)

Especially since most file managers are Desktop dependent (KDE, Gnome, Xfce, etc.), requiring you to load all kinds of unwanted bloat onto your system.
