Free beyond the red line software for linux

The Fedora Project is an openly-developed project designed by Red Hat, open for general participation, led by a meritocracy, following a set of project objectives.
The goal of The Fedora Project is to work with the Linux community to build a complete, general purpose operating system exclusively from open source software. Development will be done in a public forum.
The project will produce time-based releases of Fedora Core about 2-3 times a year, with a public release schedule.
The Red Hat engineering team will continue to participate in building Fedora Core and will invite and encourage more outside participation than in past releases.
By using this more open process, we hope to provide an operating system more in line with the ideals of free software and more appealing to the open source community.
Main features:
- Support for the PowerPC (PPC) architecture.
- GCC 4.0
- GNOME 2.10
- KDE 3.4 includes new accessibility features. You can manage these new features in KDS Control CenterRegional & AccessibilityAccessibility.
- Native Eclipse 3.1M6 (part of a free Java stack)
- MySQL 4.1
- PHP 5.0
- Xen 2 (virtualization to run multiple versions of an OS)
- GFS 6.1-0.pre22 (cluster file system)
- Evince 0.2.1 (universal document viewer)
- GDM 2.6 - Includes early login capability
- SELinux This release includes coverage for 80 new daemons by the targeted policy. There are changes to the handling of Booleans. The targeted policy is enabled by default.

GNU ed is a line-oriented text editor. GNU ed is used to create, display, modify and otherwise manipulate text files, both interactively and via shell scripts.
A restricted version of `ed, `red, can only edit files in the current directory and cannot execute shell commands. `ed is the `standard text editor in the sense that it is the original editor for Unix, and thus widely available.
Enhancements:
- The testsuite now exits unsuccesfully in case of error.
- Some minor problems in the manual page have been fixed.
- The GFDL has been added to the info file.

Tk::DiffText is a Perl/Tk composite widget for colorized diffs.

SYNOPSIS

use Tk::DiffText;

my $w = $mw->DiffText()->pack();

$w->diff($file0, $file1);

This module defines a composite widget that makes it simple to provide basic "diff" functionality to your Tk applications.

OPTIONS

-orient => horizontal|vertical
Controls the arrangement of the text panes. Defaults to vertical.
-gutter => 0|1
Hides and displays the line number gutter. Defaults to 1.
-gutterforeground => color
Sets the gutter foreground color.
-gutterbackground => color
Sets the gutter background color.
-diffcolors => {...}
Sets the colors used for highlighting diff results. The structure of the value hash is as follows:
{
add => [-fg => green ], # tag for additions
del => [-fg => red, -overstrike => 1], # tag for deletions
mod => [-fg => blue ], # tag for changes
pad => [-bg => #f0f0f0], # tag for blank line padding
}

For each of the tags you can specify any option that is valid for use in a ROText widget tag: -foreground, -background, -overstrike, etc.
-map => scaled|scrolled|none

Controls the display and type of difference map. Defaults to scaled.

The difference map will match its colors to those from -diffcolors by default. It uses the background color if specified, otherwise it uses the foreground color.

Devel::tcltkdb is a Perl debugger using a Tk GUI.
tcltkdb is a debugger for perl that uses perl+Tcl/Tk for a user interface.
Main features:
- Hot Variable Inspection
- Breakpoint Control Panel
- Expression List
- Subroutine Tree
SYNOPSIS
To debug a script using tcltkdb invoke perl like this:
perl -d:tcltkdb myscript.pl
Usage
perl -d:tcltkdb myscript.pl
Code Pane
Line Numbers
Line numbers are presented on the left side of the window. Lines that
have lines through them are not breakable. Lines that are plain text
are breakable. Clicking on these line numbers will insert a
breakpoint on that line and change the line number color to
$ENV{PTKDB_BRKPT_COLOR} (Defaults to Red). Clicking on the number
again will remove the breakpoint. If you disable the breakpoint with
the controls on the BrkPt notebook page the color will change to
$ENV{PTKDB_DISABLEDBRKPT_COLOR}(Defaults to Green).
Cursor Motion
If you place the cursor over a variable (i.e. $myVar, @myVar, or %myVar) and pause for a second the debugger will evaluate the current value of the variable and pop a balloon up with the evaluated result. This feature is not available with Tk400.
If Data::Dumper(standard with perl5.00502)is available it will be used to format the result. If there is an active selection, the text of that selection will be evaluated.

STX B+ Tree project is a set of C++ template classes implementing a B+ tree key/data container in main memory. The classes are designed as drop-in replacements of the STL containers set, map, multiset and multimap and follow their interfaces very closely. By packing multiple value pairs into each node of the tree the B+ tree reduces heap fragmentation and utilizes cache-line effects better than the standard red-black binary tree.
The tree algorithms are based on the implementation in Cormen, Leiserson and Rivests Introduction into Algorithms, Jan Janninks paper and other algorithm resources. The classes contain extensive assertion and verification mechanisms to ensure the implementations correctness by testing the tree invariants.
The main B+ tree implementation can be found in doxygen stx/btree.h or with plain text comments btree.h.
Special interest was put into performing a speed comparison test between the standard red-black tree and the new B+ tree implementation. The speed test results are interesting and show the B+ tree to be significantly faster.
Enhancements:
- This release introduces the demonstration program wxBTreeDemo.
- This program draws illustrations of the B+ trees constructed by the STX B+ Tree template classes.
- It allows the user to select different types of B+ tree instantiations: integer or string keys and different slot numbers.
- The user may insert and erase key/data pairs from the tree and run different search operations.
- The demo program uses the cross-platform wxWidgets toolkit and can be compiled on Linux, Windows, and Mac OS X.
