Free a5 paper size software for linux

Pysize is a graphical and console tool for exploring the size of directories. The project is written in Python, and requires Python ≥ 2.4 and pygtk ≥ 2.8 if you want to use the GUI.

Three user interfaces are available using the --ui command line option, the best available is chosen by default.

Paper Harbour is a software based system which allows you to securely organise and distribute your electronic documentation.
Paper Harbour runs over a network and allows clients to access a central document archive. Paper Harbour is compatible with both Windows and Linux platforms and is designed to work with MySQL open source database, although it is compatible with other databases.
Paper Harbour can provide a central point for information exchange in the form of shared documents.
Whether the organisation is project based, product based or service based Paper Harbour can provide structure and tools to aid business development.
Paper Harbour doesnt only store documents, it stores information about the documents. It also includes functionality which supports distribution of documents, unique document ids, document reviews, searching and more.
Paper Harbour is designed to be simple so that users do not need a high degree of technical knowledge to be able to use it. This simplicity is defined in the concept which Paper Harbour is built on.
Paper Harbour is also designed as a platform for document management. It can be installed and run with the standard functions or it can be modified to include customer specific functions. In addition, Paper Harbour is supplied with the source code so our customers are free to make their own modifications.
The Paper Harbour has been designed so that it is compatible with Open Source solutions. This means that our customers can reduce their implementation cost. Supporting Technologies Nordic are committed to ensuring that Paper Harbour is affordable for all sizes of organisations, so that smaller organisation can have access to the same technologies that large organisations use.
Main features:
- Centralised Storage
- Automatic Distribution
- Version and Change Control
- Security

Optar stands for OPTical ARchiver. This project is a codec for encoding data on paper. Optar fits 200kB on an A4 page, then you print it with a laser printer. If you want to read the recording, scan it with a scanner and feed into the decoder program.

A practical level of reliability is ensured using forward error correction code (FEC). Automated processing of page batches facilitates storage of files larger than 200kB.

LMS (LAN Management System) is the integrated system of networks management designed for various size internet providers (ISP).

That software writed in PHP, Perl and C, works with variuos database systems.

The metric implemented in the Image::Density Perl Module estimates the density of data where there is data, and has a reasonable correlation with goodness as judged by humans.

That is, if you let a human look at a set of images and judge quality, the density values for those images as calculated here tend to correlate well with the human judgement (densities that are too high or too low represent "bad images).

This project is intended for use on bitonal TIFF images, such as those from scanning paper documents.

Mapyrus project can create plots of points, lines, polygons and labels to PostScript (high resolution, up to A0 paper size), Portable Document Format (PDF), Scalable Vector Graphics (SVG) format and web image output formats.
Mapyrus is freely-available and is implemented entirely in Java enabling it to run on Linux, Sun Solaris, MicroSoft Windows and other platforms for which Java is available.
Main features:
- A Logo or turtle graphics program.
- An imaginary pen is moved around a page, creating shapes that are drawn into an image file. Reusable routines are built up using a BASIC-like language. Branching and looping constructs enable complex shapes, symbols and patterns to be be defined.
- Reading and displaying of geographic information system (GIS) datasets, text files, or tables held in a relational database (including spatially extended databases such as PostGIS and MySQL).
- Drawing routines are applied to geographic data to produce annotated and symbolized maps and graphs. Attributes of the geographic data control the color, size, annotation and other characteristics of the appearance of the geographic data. Scalebars, legends, coordinate grids and north arrows are also available.
- Integration with the freely-available Java Topology Suite from Vivid Solutions. This library provides geometric algorithms such as buffering, point-in-polygon test and polygon intersection.
- Integration with the ogrinfo program, part of the freely-available OGR library. This program provides access to many GIS data formats.
- Flexibility. Running in one of two ways.
- As a stand-alone program for integration into scripts and batch tasks (suitable for generating a one-off map or a series of similar maps from a template showing different areas, or using different criteria for each map).
- As a self-contained web server providing map and graph images to a web-based application. This also enables Mapyrus to be integrated into larger applications (such as PHP-based applications), with map images fetched using HTTP requests.
Enhancements:
- Upgrade to Java version 1.5.
- Enable shell environment variables to be used directly in Mapyrus.
- Fix reading of ESRI Shape files to correctly read zero width attribute fields, files containing only a single point, and MULTIPOINT geometry having only one point.

Cadabra is a computer algebra system for the manipulation of what could loosely be called tensorial expressions.
Cadabra is aimed at, though not necessarily restricted to, theoretical high-energy physicists. Because of its target audience, the programs interface, storage system and underlying philosophy differ substantially from other computer algebra systems.
Main features:
- Usage of a TeX-like notation, which eliminates many errors in transcribing problems from paper to computer and back.
- Built-in understanding of dummy indices and dummy symbols, including their automatic relabelling when necessary. Powerful algorithms for canonicalisation of objects with index symmetries, both mono-term and multi-term.
- A typing system through properties, but freedom to dispense with this system entirely when it is not needed.
- A new way to deal with products of non-commuting objects, enabling a notation which is identical to standard physicists notation (i.e. no need for special non-commuting product operators).
- A flexible optional undo system. Interactive calculations can be undone to arbitrary level without requiring a full re-evaluation of the entire calculation.
- A simple and documented way to add new algorithms in the form of C++ modules, which directly operate on the internal expression tree.
Cadabra has been under development for some time now, but has never left my own computer. The current version is the first public release, intended to collect feedback from a wider audience. So, feel free to mail me at kasper.peeters (at) aei.mpg.de with suggestions or constructive criticism.
Enhancements:
- Many new algorithms were added.
- The GUI was improved with progress bars, font size selection, and cut and paste.
- Many bugs were fixed.
- This version compiles cleanly on all versions of OS X as well as on 64-bit platforms.
