Free universal software for linux

SYNOPSIS

require UNIVERSAL::derived_classes;

package A;

package B;
@ISA = qw( A );

package C;
@ISA = qw( B );

package main;
my @derived_classes = A->derived_classes; # B, C
my @derived_classes_reversed = A->derived_classes_reversed; # C, B

UNIVERSAL::derived_classes provides the following methods:

CLASS->derived_classes(REVERSED)
$obj->derived_classes(REVERSED)

Where

REVERSED

is the flag to reverse classes

When used as a class method (CLASS->derived_classes(REVERSED)), derived_classes returns derived classes of the CLASS.

When used as an instance method ($obj->derived_classes(REVERSED)), derived_classes returns derived classes of a class where $obj is blessed.

If the REVERSED flag is true then reversed derived classes are returned.

CLASS->derived_classes_reversed
$obj->derived_classes_reversed
derived_classes_reversed is same as derived_classes(REVERSED)

Firefox Universal Uploader is a Firefox extension that allows you to upload/download files from any website using a friendly interface. Upload files/photos/videos to Flickr, Picasa, Youtube, Box.net(1GB of free space) are Facebook in this version. Next versions would support other websites like Google Videos, Webshots etc.
Thumbnail view of local and remote files will be given in the next version. You can add multiple files to the queue at a time. Extension will take care of uploading them for you.
Main features:
- It shows the local folders and remote folders which enables you to upload files by single click.
- You can upload any number of files at a time.
- You can upload files to multiple websites using a single interface (using only one extension).
- Ability to add multiple accounts and upload files to each account independently.
- Site specific features are also included and will be improved in the coming versions. eg. Box.net: giving public/private access to files.

PXES project is a micro Linux thin client distribution. PXES will boot a real thin client or will help to convert in minutes any compliant hardware (see list bellow) into a versatile thin client.
They will be capable of accessing any XDM server presenting the graphical login screen or any Microsoft Terminal Server through RDP protocol. The actual configuration of clients is made with an easy to use graphical configuration tool, allowing the specification of clients parameters or the server to access to.
You can recover hardware that is useless running current desktop OS or office package and give it a second chance. This thin client boots from the network with PXE (Intel Pre-Execution Environment specifications) so neither boot diskette nor boot eprom is needed.
The linux kernel and an initial root filesystem is transmitted over the network (the compressed size as of version 0.4 is about 4M).
Main features:
Supported servers and protocols
- Unix/Linux supporting XDM
- Microsoft Terminal Server using RDP
- Citrix using ICA
- VNC using TightVNC
- LOCAL local graphical session with simple desktop
- LTSP or K12LTSP
- IBM Host using 3270 or 5250 emulation (soon)
- Telnet emulating ANSI terminal
- SSH
- Tarantella using proprietary protocol
- NoMachine using NX
- Thinlinc
Boot methods
- PXE network card included in most modern PC hardware
- Etherboot to boot from diskette or EPROM
- CD-ROM
- Hard disk
- DOC DiskOnChip and DOM DiskOnModule
- USB Storage
- For Hard Disk, DOC, DOM or other flash memory installation you may also use PXES HD/DOM Installer (http://pxes.sourceforge.net/enterprise/install-dom.shtml) which is part of Enterprise Edition (http://pxes.sourceforge.net/enterprise/index.php).
- You can also see the detailed information about Boot Methods.

- BUS: PCI recommended (although ISA works)
- RAM: 32 Mb recommended (16 Mb minimum)
- NIC: see supported network card list
- Video: see supported video card list
Local devices

- Serial devices (bar code reader, etc.)
- Audio
- Flash memory / USB storage
Supported operating system
- Linux
- Solaris
- AIX
- SCO
- BSD
- HP-UX
- Microsoft Windows NT4
- Microsoft Windows 2000
- Microsoft Windows 2003
- Microsoft Windows XP
Enhancements:
- Support for different boot loaders was added.
- Support for GRUB on ISO images was added.
- A correction was made in the kernel and image path in isolinux.
- A message telling the user to run "pxesconfig --updatefstab" was added.
- updatefstab was added in post.
- Support for 2.4.32 and 2.6.15 kernels was added.
- Automated owner and permission changing on specific files was added, so now the whole pxes-base tree can be checked out as a normal user.

Linux X10 universal device driver (also known as Project WiSH) provides a /dev interface to an X10 network through a combination of Linux kernel modules and daemons.
It is intended to provide a standard interface and syntax to shell script utilities (such as cat and echo), Perl scripts, C programs, or Java programs so that everything from a quick hack to a more advanced program can manipulate the X10 devices in an automated home regardless of the transceiver used.
Its simplest use is with shell scripts (examples of which are provided in the package). Currently the project supports the 3 X10 transceivers (PowerLinc Serial, PowerLinc USB, and CM11A).
Main features:
- Full /dev/x10 capability with enhancements for non-blocking writes
- Full support for PowerLinc Serial transceiver
- Full support for CM11A Serial transceiver
- Full support for PowerLinc USB transceiver (with kernel patches for USB)
Enhancements:
- X10 state machine simulator runs in userspace
- Kernel module maintains status of individual devices and implements API only
- non-blocking writes (by popular demand) so commands can be queued up in rapid succession
- PowerLinc USB now uses HID interface
- Version 2.0 drivers work with kernel 2.6.7 and higher and with kernel version 2.4.0 (the PowerLinc USB will not work with kernel 2.4 due to lack of support for multibyte messages in the USB subsystem of the kernel. If you require the PowerLinc USB and kernel 2.4, use wish-1.6.10. )
- Simpler compilation and installation method

Quite Universal Circuit Simulator (Qucs) is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit. After that simulation has finished you can view the simulation results on a presentation page or window.

The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Harmonic Balance analysis, noise analysis, etc.

Qucsator, the simulation backend, is a command line circuit simulator. It takes a network list in a certain format as input and outputs a Qucs dataset.

Whats New in This Release:

The new release comes with a new translation into Ukrainian, a selectable preprocessor in the SPICE file component and two new components, i.e. an exponential voltage and current source. Libraries
can now contain analogue as well as digital subcircuits. Analogue modelling is substantially strengthened by symbolically defined devices. And last but not least pure digital simulations can be also performed by Verilog-HDL as an alternative to VHDL.

In the simulation backend the equation defined devices (EDD) have been implemented as well as the two new signal sources. Also the list of
available functions in the equation solver has been extended to support vt(), hypot(), limexp(), arcsec(), arccosec(), arsech() and arcosech(). Furthermore logical and rational operators as well as the ternary ?: construct can be used in equations.

u2nl provides a universal transparent HTTPS proxy tunnel.
u2nl (u-tunnel, universal tunnel) is a small application that listens on a TCP port and tunnels all connections transparently via an HTTPS proxy (using the CONNECT command) to the Internet.
Another host on the Internet is not needed. This only works if the HTTPS proxy allows these CONNECT connections.
It can be used to provide a Linux host with full connectivity when everything except the http proxy is blocked by a firewall.
Usage
I assume now, you have found out the ip address and port of the https proxy we use for tunneling. You have to make sure, that your Linux host forwards all connections to a port, u2nl is listening on. Do something like the following (replace OUTPUT by PREROUTING if the Linux computer is only a gateway):
# iptables -t nat -A OUTPUT -p tcp -d ! -j REDIRECT --to-port
Where is the ip address/hostname of the proxy host and is the port (you choose, something above 1024) u2nl will be listening on. Now start u2nl:
# u2nl
Where is the port of the https proxy (normally 8080 or 80) and is the (same as above) port u2nl will be listening on. The tunnel should work now.
Enhancements:
- The Makefile has been improved.
