Free large number software for linux

number is a perl script that will print the English name of a number. One can print names of extremely large numbers (e.g. 1e1234567). Number can be run on the command line, or as a CGI script when run as number.cgi.

Number prints names in both the American and European naming system. It can also print the decimal expansion of a number in either naming system.

StrongBox is a next generation Linux-based operating system, incorporating tight version control, digital signatures, high security and built-in change management.
StrongBox represents a shift in the Linux paradigm. Moving away from monolithic systems where everything runs together, StrongBox is a fully modular Linux distribution.
It incorporates a small ram-based OS and toolset for administration and security functions, and then allows applications bundles, built using any Linux distribution, to run on top of it. Each of these bundles, running in a secure virtual context, has a large level of independence from the base OS.
This secure partitioning allows StrongBox to have some unique and powerful features. OS versioning, rollbacks, automated hardware detection, fault-tolerant boot process, easy migration from server-to-server, and the ability to incorporate other Linux distributions and existing installations are key features.
StrongBox gets its name from the high standard of security that it provides. Using virtual servers, digital signatures on all OS components, and a large number of read-only pieces in the OS, StrongBox is highly resistant to security breaches.
Also, it has virtual boot medium independence, meaning that it can run with little or no changes from CDRom, compact flash, USB, SCSI, etc. This makes StrongBox ideal for the secure deployment of embedded systems, computing clusters, enterprise Linux deployments, secure web servers, PBX systems, and kiosk systems.

The Blowfish cipher in C and i386 assembler.

In cryptography, Blowfish is a keyed, symmetric block cipher, designed in 1993 by Bruce Schneier and included in a large number of cipher suites and encryption products. While no effective cryptanalysis of Blowfish has been found to date, more attention is now given to block ciphers with a larger block size, such as AES or Twofish.

Schneier designed Blowfish as a general-purpose algorithm, intended as a replacement for the aging DES and free of the problems associated with other algorithms. At the time, many other designs were proprietary, encumbered by patents or kept as government secrets. Schneier has stated that, "Blowfish is unpatented, and will remain so in all countries. The algorithm is hereby placed in the public domain, and can be freely used by anyone."

YALE short from Yet Another Learning Environment is a flexible open-source tool for knowledge discovery, machine learning experiments, and data mining applications.

Experiments can be made up of a large number of arbitrarily nestable operators and their setup is described by XML files which can easily be created with a graphical user interface. Applications of YALE cover both research and real-world data mining tasks.

YALE is an environment for rapid prototyping of data mining applications. A modular operator concept allows the design of complex nested operator chains for a huge number of learning problems.

The data handling is transparent to the operators. They do not have to cope with the actual data format or different data views - the YALE core takes care of the necessary transformations. YALE is widely used by researchers and in industry.

PicoStorage allows you to store hierarhical information (similar to "files and directories") inside a single file. The functionality offered is largely equivalent to the one offered by any filesystem, or by the Structured Storage and Compound Files.

PicoStorage can efficiently handle huge numbers of small files, with very economical disk usage; it also allows you to keep open (in RAM) simultaneously a large number of files. Transaction support guarantees data integrity.

Learn more about the distinctive advantages of PicoStorage. or look at the benchmark.

The library is available on a dual-license basis: under GPL for free, and under a commercial license for use in closed-source applications.

Using

The library contains the classes File and Dir to represent files and directories. On a File you can read or write a number of bytes from a given offset, and set/get the file size. On a Dir you can create entries (either files or subdirectories), open entries, delete entries, and iterate over the directorys content.

The storage itself (i.e. the whole hierarchical structure, contained in a filesystem file) is represented by the class Storage. Using this class, you can create or open a storage, obtain the root directory of the storage, close the storage and do commit or rollback.

wxCam is a webcam application for linux. It supports video recording (in an uncompressed AVI format), snapshot taking, and some special commands for Philips webcams, so you can also use the program for astronomy purposes.

It supports video for Linux drivers, so it should work on a very large number of devices.

Open Searchable Image Catalogue (OSIC) is a system for storing large numbers of image files with associated metadata.

This data can later be used to search the database for images. Open Searchable Image Catalogue works particularly well where the images need to be accessible to a large number of people or over a large geographical distribution.

Images can be compressed (and decreased in size) on-the-fly so that they can be viewed quickly over a slow network such as the Internet.

Quantum GIS (QGIS) is a cross-platform Geographic Information System (GIS). Quantum GIS project offers support for vector and raster formats, including spatially enabled tables in PostgreSQL using PostGIS, common GIS vector formats such as Shapefiles, and geo-referenced rasters (TIFF, PNG, and GEOTIFF).
Many plugins are available to dynamically add new functionality. Viewing of GRASS layers (vector and raster) is provided by a plugin. GRASS vector layers can be edited in QGIS.
Main features:
- Support for spatially enabled PostGIS tables
- Support for shapefiles, ArcInfo coverages, Mapinfo, and other formats supported by OGR
- Raster support for a large number of formats
- Identify features
- Display attribute tables
- Select features
- GRASS Digitizing
- Feature labeling
Enhancements:
- Numerous bugfixes and stability improvements.
