Free fast data transfer software for linux

Fast Data Transfer is an application for efficient data transfers that is capable of reading and writing at disk speed over wide area networks (with standard TCP).
It can be used to stream a large set of files across the network, so a large dataset composed of thousands of files can be sent or received at full speed, without the network transfer restarting between files.
The project is written in Java, runs an all major platforms, and is easy to use.
Main features:
- Streams a dataset (list of files) continuously, using a managed pool of buffers through one or more TCP sockets.
- Uses independent threads to read and write on each physical device
- Transfers data in parallel on multiple TCP streams, when necessary
- Uses appropriate-sized buffers for disk I/O and for the network
- Restores the files from buffers asynchronously
- Resumes a file transfer session without loss, when needed

Apple Disk Transfer ProDOS (or ADTPro for short) transfers diskettes and logical disk images between Apple ][-era computers and the modern world. If youre familiar with the original ADT, ADTPro extends ADTs reach by working with more logical disk formats, drive types, communications devices, and host operating systems.
Main features:
- Compatibility with any device ProDOS can read
- Compatibility with any Apple ][ (or clone) computer with 64k memory
- Compatibility with many logical disk image formats: .DSK, .PO, .NIB, 2IMG
- Server compatibility with original ADT client program
- Server compatibility with Windows, Mac OSX, Linux, and probably Solaris
- Ability to bootstrap an Apple ][ from bare metal over serial or cassette ports
- Ability to send floppies in "batch" mode without having to name each one
Server
The server program runs on a computer capable of running Java. Depending on how you want to connect to your Apple, you might also need a serial port and cables, an Uthernet card for your apple, or a couple of audio patch cables. The server offers a compact user interface that shows what communications are taking place between the host and the Apple ][.
The servers primary role is to send and receive disk images as requested from the client. But if you have recently acquired an Apple and a disk drive, and you have no software for it - youre in a bit of a tricky situation if you want to move software from the Internet all the way to your shiny new Apple. ADTPros server can help get you get bootstrapped.
Client
The client side runs on the Apple ][. It handles most of the user interaction. When choosing disks/volumes to transfer, anything that ProDOS can see is fair game. Transferring data occurs with a 20k buffer on the Apple, so all transfers are broken up into 20k chunks. A progress indicator shows how far it is into the current chunk, as well as a running count of the total progress.
Enhancements:
- This release has been enhanced with Jean-Marc Boutillon (Deckard)s FASTDSK fast Disk II reading routines.
- This results in a speed boost of 25%-33% for Disk II to host transfers.
- Bootstrapping operations have been reduced, as there is no longer a dependency on ProDOS BASIC.

Data::CTable is a Perl module that helps you read, write, manipulate tabular data.

SYNOPSIS

## Read some data files in various tabular formats
use Data::CTable;
my $People = Data::CTable->new("people.merge.mac.txt");
my $Stats = Data::CTable->new("stats.tabs.unix.txt");

## Clean stray whitespace in fields
$People->clean_ws();
$Stats ->clean_ws();

## Retrieve columns
my $First = $People->col(FirstName);
my $Last = $People->col(LastName );

## Calculate a new column based on two others
my $Full = [map {"$First->[$_] $Last->[$_]"} @{$People->all()}];

## Add new column to the table
$People->col(FullName => $Full);

## Another way to calculate a new column
$People->col(Key);
$People->calc(sub {no strict vars; $Key = "$Last,$First";});

## "Left join" records matching Stats:PersonID to People:Key
$Stats->join($People, PersonID => Key);

## Find certain records
$Stats->select_all();
$Stats->select(Department => sub {/Sale/i }); ## Sales depts
$Stats->omit (Department => sub {/Resale/i}); ## not Resales
$Stats->select(UsageIndex => sub {$_ > 20.0}); ## high usage

## Sort the found records
$Stats->sortspec(DeptNum , {SortType => Integer});
$Stats->sortspec(UsageIndex, {SortType => Number });
$Stats->sort([qw(DeptNum UsageIndex Last First)]);

## Make copy of table with only found/sorted data, in order
my $Report = $Stats->snapshot();

## Write an output file
$Report->write(_FileName => "Rept.txt", _LineEnding => "mac");

## Print a final progress message.
$Stats->progress("Done!");

## Dozens more methods and parameters available...

OVERVIEW

Data::CTable is a comprehensive utility for reading, writing, manipulating, cleaning and otherwise transforming tabular data. The distribution includes several illustrative subclasses and utility scripts.

A Columnar Table represents a table as a hash of data columns, making it easy to do data cleanup, formatting, searching, calculations, joins, or other complex operations.

The objects hash keys are the field names and the hash values hold the data columns (as array references).

Tables also store a "selection" -- a list of selected / sorted record numbers, and a "field list" -- an ordered list of all or some fields to be operated on. Select() and sort() methods manipulate the selection list. Later, you can optionally rewrite the table in memory or on disk to reflect changes in the selection list or field list.
Data::CTable reads and writes any tabular text file format including Merge, CSV, Tab-delimited, and variants. It transparently detects, reads, and preserves Unix, Mac, and/or DOS line endings and tab or comma field delimiters -- regardless of the runtime platform.

In addition to reading data files, CTable is a good way to gather, store, and operate on tabular data in memory, and to export data to delimited text files to be read by other programs or interactive productivity applications.

To achieve extremely fast data loading, CTable caches data file contents using the Storable module. This can be helpful in CGI environments or when operating on very large data files. CTable can read an entire cached table of about 120 megabytes into memory in about 10 seconds on an average mid-range computer.

For simple data-driven applications needing to store and quickly retrieve simple tabular data sets, CTable provides a credible alternative to DBM files or SQL.
For data hygiene applications, CTable forms the foundation for writing utility scripts or compilers to transfer data from external sources, such as FileMaker, Excel, Access, personal organizers, etc. into compiled or validated formats -- or even as a gateway to loading data into SQL databases or other destinations. You can easily write short, repeatable scripts in Perl to do reporting, error checking, analysis, or validation that would be hard to duplicate in less-flexible application environments.

The data representation is simple and open so you can directly access the data in the object if you feel like it -- or you can use accessors to request "clean" structures containing only the data or copies of it. Or you can build your own columns in memory and then when youre ready, turn them into a table object using the very flexible new() method.

The highly factored interface and implementation allow fine-grained subclassing so you can easily create useful lightweight subclasses. Several subclasses are included with the distribution.

Most defaults and parameters can be customized by subclassing, overridden at the instance level (avoiding the need to subclass too often), and further overridden via optional named-parameter arguments to most major method calls.

GNOME Transfer Manager allows the user to retrieve multiple files from the web.

These files can be retrieved in multiple parts and each part retrieved on a separate session that the user is connected to the Internet. This is most useful to users with dialup connections. The program performs these tasks using wget as its back-end.

The program supports CORBA. This makes it easy for other programs to use GTransferManager to handle the transfer of files from the Internet.

The program also has an applet which communicates with program using CORBA. The applet can launch the program, request for a new download or accept drops of URLs from netscape, gFTP, gmc and give these URLs to GTM.

Parallel Three-Dimensional Fast Fourier Transforms, dubbed P3DFFT, is a library for computational computing in a wide range of sciences, such as physics, climatology, chemistry.
This project was developed at SDSC by Dmitry Pekurovsky as a product of a Strategic Applications Collaborations (SAC) project.
Main features:
- Parallel implementation with 2D data decomposition, overcoming an important limitation to scalability of other 3D FFT libraries implementing 1D, or slab, decomposition.
- Optimized for parallel communication and single-CPU performance.
- Built on top of well-optimized and flexible 1D FFT libraries.
Enhancements:
- Assorted minor bugfixes and code speedups.

Transfer to Media Device is a script that creates a new Playlist Right Click Menu item for transferring selected playlist items to your iPod via the Media Device Browser.
This script now also supports generic copy to operation for USB mass storage devices. Currently the script will prompt for a destination directory on first copy, in the future this setting will be saved in a configuration file.
This script works with amaroK 1.3beta3 and above.
Usage:
Run from the amaroK script manager. A new menu item will appear in the Playlist right mouse button menu.
Select files in the playlist and Right click -> Transfer to -> iPod for transfering to an iPod.
Select files in the playlist and Right click -> Transfer to -> USB Device for transfering to a USB device.
Enhancements:
- Add support for Creative Nomad Jukebox devices using the kionjb kioslave. Thanks to Ralf T for the patch.

GtkDatabox is a widget for the Gtk+-library designed to display large amounts of numerical data fast and easy. One or more data sets of thousands of data points (X and Y coordinate) may be displayed and updated in split seconds.
The widget is therfore used in many scientific and private projects that need to show quickly changing data "live".
GtkDatabox offers the ability to zoom into and out of the data and to navigate through your data by scrolling.
In addition to rulers and a simple coordinate cross, GtkDatabox now also allows you to add one (or even more) configurable grids like on an oscilloscope.
Data may be presented as dots, lines connecting the data, or vertical bars. The widget allows you to easily transform pixel coordinates into data coordinates, thus allowing you to easily create powerful applications for data analysis.
GtkDatabox is free software distributed under the GNU LESSER General Public License (LGPL).
Enhancements:
- Bugfix release.
- A potential memory leak has been removed from one of the graph classes (marker).

assniffer is an auto saving sniffer for windows and linux.

assniffer can monitor (using pcap) a network, and for every HTTP transfer it sees, save a copy of the transferred data.

This is less for sinister uses, and more for taking advantage of the already-transferred data that your computer may be exposed to.

Linux users should install libpcap, and tools to enable compiling.

Compilation:

- Go to the source/assniffer directory and type make.
