Free 2.0.3 software for linux

QCADesigner is the product of an ongoing research effort at the University of Calgary ATIPS Laboratory to create a design and simulation tool for Quantum Dot Cellular Automata (QCA). This tool is still under development and is provided free of cost to the research community "as is".
QCA is an emerging nanotechnology concept for the realization of a computer built with arrays of nano-scale QCA cells. These QCA cells are capable of performing all complex computational functions required for general-purpose computation.
QCA has been listed as one of the six emerging nanotechnologies with applications in future computers by the International Technology Roadmap For Semiconductors (ITRS). QCADesigner facilitates rapid design, layout and simulation of QCA circuits by providing powerful CAD features available in more complex circuit design tools.
Main features:
- Intuitive CAD-like user interface
- Easy drag-and-drop circuit design
- Encapsulated PostScript (EPS) printing
- Support for multiple layers (for signal crossover)
- Multilingual support (de hu ro fr - so far)
Enhancements:
- This is a minor bugfix release featuring an improved layer mapping dialog.
- However, the most important change is on the Windows front: The Windows version of QCADesigner now uses the Gaim version of the GTK+ Runtime Environment.
- The new version allows you to upgrade from the dropline.net version of GTK+.

CD-Rchive2 is a complete revamp of the popular but now aged CD-Rchive program. It is intended to be used with cdrecord-ProDVD, cdda2wav, and mkisofs for the production of data and music CDs and data DVDs.
Built in tools allow cloning of a complete CD or DVD and writing copies. A Boot Wizard will guide you through steps required to make a bootable CD or DVD, write the code, and compile a binary menu program which runs with isolinux.
Enhancements:
- Functionality was added when ripping tracks from CD to automatically convert to .mp3 instead of .wav via a checkbox on the .wav tab page.
- This requires lame to be installed.
- A problem of occassional incorrect audio device specification on single device machines such as laptops was fixed.

OSSP var is a flexible, full-featured and fast variable construct expansion library. It supports a configurable variable construct syntax very similar to the style found in many scripting languages (like @name, ${name}, , etc.) and provides both simple scalar (${name}) and array (${name[index]}) expansion, plus optionally one or more post-operations on the expanded value (${name:op:op...}).
The supported post-operations are length determination, case conversion, defaults, postive and negative alternatives, sub-strings, regular expression based substitutions, character translations, and padding.
Additionally, a meta-construct plus arithmetic expressions for index and range calculations allow (even nested) iterations over array variable expansions (..[..${name[#+1]}..]..). The actual variable value lookup is performed through a callback function, so OSSP var can expand arbitrary values.
Hint: There is also an ISO C++ derivative of the OSSP var library, named libvarexp. It is based on a development version of OSSP var and hence does not provide exactly the same amount of functionality. But it provides an ISO C++ API and so can be of interest to you if you are programming in ISO C++ (where OSSP vars ISO C API might be too boring for you).
Enhancements:
- Fix some sprintf(3) parameter passing. [Ralf S. Engelschall]
- Upgraded build environment to GNU libtool 1.5.20 and GNU shtool 2.0.3. [Ralf S. Engelschall]
- Bumped year in copyright messages for new year 2005. [Ralf S. Engelschall]

OSSP defines an abstract data type of a data buffer that can assemble, move and truncate chunks of data in a stream but avoids actual copying.
It was built to deal efficiently with communication streams between software modules. It especially provides flexible semantical data attribution through by-chunk labeling.
It also has convenient chunk traversal methods and optional OSSP ex based exception handling.
Enhancements:
- An Autoconf check is provided for the va_copy(d,s) macro.
- The build environment was upgraded to GNU autoconf 2.59, GNU libtool 1.5.20, and GNU shtool 2.0.3.

PAUD (Parted And Utilities Disk) is a Linux utility boot disk distribution. It fits on a single 1.44 floppy disk. It contains mc, parted, and other utilities such as filesystem utilities for ext2, ext3, and Reiserfs. It is great for partition maintenance and for rescue purposes.
The latest version of PAUD (1.0.4) has glibc-2.2.5, kernel 2.4.20, support for up to 4 virtual consoles. Kernel has DMA support (click here for more info on DMA) , SCSI support is not available out-of-the-box but it can be easily implemented.
The kernel has filesystem support for FAT/VFAT, EXT2, EXT3, ReiserFS 3.5, and ReiserFS 3.6 filesystems. Parted supports creating, resizing, copying, and destroying of these filesystem types (please read notes for reiserfs and ext3).
This is a list of all the commands, some of these commands are internal commands of busybox:
busybox commands:
[, ash, basename, busybox, cat, chgrp, chmod, chown, chroot, chvt, clear, cp, cut, date, dd, df, dirname, dmesg, du, echo, env, false, find, free, grep, gunzip, gzip, halt, head, id, init, kill, killall, klogd, linuxrc, ln, logger, ls, lsmod, mkdir, mknod, mkswap, modprobe, more, mount, mv, pidof, poweroff, ps, pwd, reboot, reset, rm, rmdir, sed, sh, sleep, sort, swapoff, swapon, sync, syslogd, tail, tar, test, touch, true, tty, umount, uname, uniq, uptime, wc, which, whoami, xargs, yes, zcat
Other commands:
e2fsck, hdparm, mc, mkreiserfs-3.5, parted, reiserfsck, tune2fs
Notes:
SCSI: SCSI support is not enabled in the kernel, if you wish to use scsi devices with PAUD, you can make a custom kernel and put it on the disk with the rootdisk. The docs section on the PAUD project page will show you how.
ntfs: Many people have asked about NTFS support, specifically the ntfsresize program. I cant fit this on the floppy, but an optional expansion floppy solution will be available shortly.
ReiserFS: mkreiserfs-3.5 can only make reiserfs filesystems version 3.5, if you want to make reiserfs version 3.6, use parted. All other reiserfs functions in parted, including resize, work for both versions. Run reiserfsck --fix-fixable after modifying any paritions from parted, to fix any potential problems.
Ext3: parted cannot create ext3 filesystems, although there is a simple way to do it in PAUD. First create an ext2 partition from parted, then create a journal to convert it to ext3 with tune2fs -j.
hdparm/DMA: DMA isnt enabled by default, hdparm fixes this problem by allowing you to enable DMA using the -d1 option. Using the hdparm disk speed test, i saw an increase in speed from 4.6 mb/sec (default) to 25.2 mb/sec (dma enabled).
mc: mc is a great way of transferring files between filesystems (for Windows/DOS users) or for editing files if you need to. It can also be useful if you ever need to use PAUD for rescue purposes.
mounting: If you get an error when mounting that a filesystem cannot be found on the device, a different filesystem may have been found. Type mount to see if it was actually mounted or not.
Enhancements:
- The kernel was updated to 2.4.20 to support hard drives that are greater than 137GB.
