Free jay software for linux

JayOS is a live CD distro intended for use as a more secure mobile environment. JayOS integrates in-RAM filesystem encryption with plausible deniability for a system that can be difficult to alter without rebuilding.
This offers a user with a high degree of data integrity; since all filesystems are either static or encrypted, the system is resistant to physical attacks.
Features 2.6 kernel, unionfs, many network security and filesystem tools, UML, and QEMU. It runs well on low-end x86 hardware, and requires only 128MB RAM and a bootable CD drive to get started.
There is some PowerPC support. Also included is standard desktop software. It is based on Linux From Scratch.
Enhancements:
- The Web site was updated to be more user-friendly.
- A new hcreate script will build an ISO with a blessed HFS+ filesystem suitable for booting Intel machines with EFI firmware.

J-Nix provides everything the home user needs, and as little else as possible. This makes J-Nix more secure, faster to run, faster to install.

The things the home user needs are

* browser,
* email,
* chat,
* word processor,
* spreadsheet program,
* presentation program.

Mozilla and Open Office do these well, better than Microsoft does and with incredibly fewer vulnerabilituies to hackers, worms and viruses.,

We took a lot of material only of interest to programmers OUT.

Then we made it as easy as possible to use the first time. Insert the CD and one boots to a pleasant screen ready to browse, email, instant message or look at news. We used through Mozilla (FireFox) for most of the web and Gaim for instant messaging.

We took out compilers, seven different text editors, web servers, email servers, several emulators, and localization except for US English.

We took out almost 200 M bytes from the CD, and a Gig from the hard drive space used.

We left in the system tools for getting packages, apt and kpackage so a web savvy user can add in any package they need.

Easier to start with. Easy to add what you need. What could be better?

Numarray provides array manipulation and computational capabilities similar to those found in IDL, Matlab, or Octave. Using numarray, it is possible to write many efficient numerical data processing applications directly in Python without using any C, C++ or Fortran code (as well as doing such analysis interactively within Python or PyRAF).
For algorithms that are not well suited for efficient computation using array facilities it is possible to write C functions (and eventually Fortran) that can read and write numarray arrays that can be called from Python.
Numarray is a re-implementation of an older Python array module called Numeric. In general its interface is very similar. It is mostly backward compatible and will be becoming more so in future releases. Numarray offers more capability than Numeric but is still behind Numeric in some areas:
numarray is efficient for large arrays (>20,000 elements) but is slower than Numeric for small arrays by a factor of 2 to 4.
numarray has a smaller selection of addon packages. numarray currently has ports of Numeric packages for linear algebra, random numbers, and fourier transforms. numarray has native packages for convolution and multi-dimensional image processing. Most Numeric extensions (C or Fortran) can be ported to numarray with minimal effort.
numarray is sufficiently developed to be useful for a number of applications, and is being used in the Hubble Space Telescope data processing pipeline (for the Advanced Camera for Surveys) and to develop the Cosmic Origins Spectrograph pipeline. PyFITS is also based on it. Most of STScIs future astronomical data processing applications will be built using its capabilities.
Numarray is being developed as an Open Source project on SourceForge from which the current development source code may be obtained. The Science Software Branch at STScI is leading this development effort.
STScI has settled on the matplotlib plotting package as the recommended 2-d data visualization tool for numarray data. While its support for numarray and Tkinter is now present, we are holding off a bit before recommending its use for all users. If you dont mind possible problems with installation or some holes in functionality it can be used now. We are in the process of improving the installation documentation for use with numarray.
Although matplotlib has its heritage in trying to emulate matlab plotting capabilities from Python, it does not require matlab. Currently the documentation is geared towards those more familiar with matlab, though many users will have no problem generating simple plots with it. It is still undergoing considerable development (by the original author, John Hunter, and with contributions by STScI and others) and we hope to fill the holes in functionality in the coming months. Nevertheless, it is capable of doing many things now.
Enhancements:
ENHANCEMENTS
- Speed improvement for numarray operators. The Python level hook mapping numarray operators onto universal functions has been moved down to C.
- Speed improvement for string-array comparisons, any(), all(). String correlation is ~10x faster.
- Better operation with py2exe to help it automatically detect the core numarray extensions to include in an installer.
- scipy newcore compatible lower case type names (e.g. int32 not Int32)
- scipy newcore dtype keyword and .dtypechar attribute.

HTMLatex is a mod_python application that uses memcached to reduce the massive overhead of repeatedly rendering the same equation. It has an option to sanitize the latex source removing any potentially dangerous code. Currently it is only tested on Apache 2 + mod_python with python 2.3 and py-memcached-1.2. It is fairly generous about the HTML and latex it accepts.
Im unsure if this will work on Windows as I paid zero attention to interoperability.
HTMLatex has two main goals: first, I wanted to avoid preprocessing; I wanted to be able to type the raw latex into an HTML document and be finished. Second, I wanted the HTML/Latex file to remain untouched.
There is one option: DEBUG. If DEBUG is set, the intermediate files are maintained on disk in /tmp/htmlatex -- this is the only method available for helping to troubleshoot latex errors. Oddly enough, performance should theoretically *increase* if debug mode is on as it doesnt require repeated filesystem access to delete files.
There used to be another option: SANITIZE, which checked the latex source for dangerous code and replaces it with a sanitized graphic. I decidd that giving people the option to auto-render latex code over the web that could do arbitrary things to their PC was a bad idea.
All latex code is sanitized now. If you want to turn it off, just comment out all of the _sanitize() calls in Equation._translateToTex().
Enhancements:
- Internet Explorer users can now see the rendered equations.
- Memcached is no longer used. Instead, images are served from the filesystem.

RawFrames provides an utility for sending crafted Ethernet frames.
RawFrames is a program written in c++ that allows you to send various types of ethernet frames from the command line. At the datalink layer, RawFrames supports Ethernet II, 802.3, LLC (802.2), LLC/SNAP and 802.1Q.
At the Network layer, RawFrames can send IP packets, but thats not really the point ;) I do however intend to increase the support for layer 3 and 4 protocols. The code used for encapsulating with these types is included as interfacable C++ Class Modules, in case youre writing an network implementation.
Should work on most versions of Linux. If you want to help port it, let me know.
Compiled on the following platforms:
.Redhat-7.2
.Redhat-7.3
.Redhat-9.0
.Slackware-7.0
Enhancements:
- Added IEEE 802.1q support

Paper::Specs is a Perl module with size and layout information for paper stock, forms, and labels.

SYNOPSIS

use Paper::Specs units => "cm";
my $form = Paper::Specs->find( brand => "Avery", code => "1234");

use Paper::Specs units => "cm", brand => "Avery";
my $form = Paper::Specs->find( code => "1234");

# location of first label on sheet
my ($xpos, $ypos) = $form->label_location( 1, 1);
my ($h, $w) = $form->label_size;

I appologise in advance for the hasty nature of this code. I want to get it out to support some other code I am writing. I promise to revisit it shortly to clear up the rough patches - however your valuable input is most welcome.

CAVEAT ALPHA CODE - This is a preliminary module and will be subject to fluctuations in API and structure based on feedback from users.

I expect that there will be some interest in this code and it should firm up quickly.

If this module does not deliver what you are looking for then you are encouraged to contact the author and voice your needs!

OTHER LABELS - I know about the Labels.xml file which is part of OpenOffice but have not figured out how it is encoded. I have the gLabels specifications file too. I plan to use these to help populate the data for this module.
