Free visual basic software for linux

Vista Basic provides a theme similar to Microsoft Vista.

window borders similar to those of Microsoft Vista when using non Aero compatible software (such as JRE 6 or Photoshop CS 2)

MWChat Basic (My Web based Chat) is the free version of our online chat system.

Licenses are IP based, one license per IP.

It has support for multiple rooms and languages, a large number of IRC-like commands, private messages and rooms, message encryption, buddy lists, logging, registered users, chat profiles, file sharing, and more. It is a very lightweight, full-featured, and secure chat room.

Visual Automata Simulator is a tool for simulating, visualizing and transforming finite state automata and Turing Machines.
Visual Automata Simulator is a DFA, NFA and TM simulator.
Main features:
- Creates, simulates and transforms DFA and NFA machines
- Creates and simulates TM
- Batch tests for TM: useful features to test a bunch of files quickly!
- Easy-to-use GUI interface (multi-documents)
- Smart links between objects
- Machines can be drawn using the mouse - and resized at any time
- Multiple machines can be created in a single document
- Multiple documents can be opened at the same time
- Documents can be saved and reloaded from disk
- Debug mode to see exactly how the machine is working (each step has a different color)
- MacOS X GUI compliant.
Enhancements:
- FA and TM machine can be exported to EPS file
- integrated update manager
- preferences: can specify the character used to define an epsilon transition
- fixed a bug where epsilon transition were not considered when starting directly from a state instead of following a non-epsilon transition.

Visual F-Prot is an F-Prot Antivirus for Linux Workstations graphical interface.

Visual F-Prot is graphical interface for F-Prot Antivirus(TM) for Linux Workstations for home use (available for free download) copyrighted by Frisk Software International (www.firsk.is). Before you install this program, you must install F-Prot Antivirus, because it wont work without it.

It works with F-Prot antivirus version 4.5.3 and above - its not tested with earlier versions,but it should also work with them.

Also, youll need "xterm" terminal emulator, provided by most, if not all linux distributions.

This program is built with GTKMM 2.4 C++ libraries, so youll also need those for it to work.

The programming of measurement instruments can be real pain. There are many different protocols, sent over many different interface and bus systems. For every programming language you want to use, you have to find libraries that support both your device and its bus system.
In order to ease this unfortunate situation, the VISA [1] specification was defined in the middle of the 90ies. Today VISA is implemented on all significant operating systems. A couple of vendors offer VISA libraries, albeit mostly in binary form.
These libraries work together with arbitrary peripherical devices, although they may be limited to certain interface devices, such as the vendors GPIB card. Virtual Instrument Software Architecture
The VISA specification has explicit bindings to Visual Basic, C, and G (LabVIEWs graphical language). However, you can use VISA with any language capable of calling functions in a DLL. Python is such a language.
PyVISA project is a VISA binding for Python. In relies on an external library file that you can download from your interface vendors web pages (National Instruments, Agilent, etc). PyVISA implements a convenient and Pythonic access to this library in two layers:
1. First, there is the lower level vpp43, which directly calls the VISA functions from Python. See the PyVISA low-level implementation for more information.
2. On top of it, an object-oriented Python module has been created called visa simply. In case of doubt, use visa because it is easier and more convenient. vpp43 is only for people who need full control or the official VISA functions for some reason. See the PyVISA manual for more information.
Enhancements:
- PyVISA can now cope with older VISA implementations, too.

W3C::LogValidator::Basic is a W3C log validator. It can sort web server log entries by popularity (hits).

SYNOPSIS

use W3C::LogValidator::Basic;
my $b = new W3C::LogValidator::Basic;
$b->uris(http://www.w3.org/Overview.html, http://www.yahoo.com/index.html);
my $result_string= $b->process_list();

This module is part of the W3C::LogValidator suite, and simply gives back pages sorted by popularity. This is an example of simple module for LogValidator.

API

Constructor

$b = W3C::LogValidator::Basic->new

Constructs a new W3C::LogValidator:HTMLBasic processor.

You might pass it a configuration hash reference (see "config_module" in W3C::LogValidator and W3C::LogValidator::Config) Particularly relevant for this module are the "verbose", "MaxDocuments" and obviously "tmpfile" (see process_list). Pass the configuration hash ref as follows:

$b = W3C::LogValidator::HTMLValidator->new(%config);

General Methods

b->uris

Returns a list of URIs to be processed (unless the configuration gives the location for the hash of URI/hits berkeley file, see process_list If an array is given as a parameter, also sets the list of URIs and returns it. Note: while this method is useful in other modules of W3C::LogValidator, this basic module is here to sort URIs extracted from Log Files by popularity, this method is hence rather useless for W3C::LogValidator::Basic.

b->trim_uris

Given a list of URIs of documents to process, returns a subset of this list containing the URIs of documents the module supposedly can handle. For this module, the decision is made based on the setting for ExcludedAreas only
b->process_list

Formats the list of URIs sorted by popularity.
Returns a result hash. Keys for this hash are:

name (string): the name of the module, i.e "Basic"
intro (string): introduction to the processing results
thead (array): headers of the results table
trows (array of arrays): rows of the results table
outro (string): conclusion of the processing results

Visual difference metrics can predict whether differences between two images are visible to the human observer or not. Such metrics are used for testing either visibility of information (whether we can see important visual information) or visibility of noise (to make sure we do not see any distortions in images, e.g. due to lossy compression).

The image below shows how two input images, a reference image (upper left) and a distorted image (lower left), are processed with the VDP to produce a probability of detection map (right). Such probability of detection map tells how likely we will notice a difference between two images for each part of an image.

Red color denotes high probability, green - low probability. Red color is mostly present in the areas where there is a snow covered path. Because of smooth texture of the snow, there is not much visual masking and distortions are easily visible.

Although there are dozens of visible difference metrics that serve a similar purpose, our Visual Difference Predictor for HDR images (HDR-VDP) has two unique advantages: firstly, our metric works with a full range of luminance values that can be meet in a real word (HDR images), and secondly, we offer a complete source code for free.

High Dynamic Range Visible Difference Predictor (HDR-VDP) can work within the complete range of luminance the human eye can see. An input to our metric is a high dynamic range (HDR) image, or an ordinary 8-bits-per-color image, converted to the actual luminance values. The proposed metric takes into account the aspects of high contrast vision, like scattering of the light in the optics (OTF), nonlinear response to light for the full range of luminance, and local adaptation.
