Free freeware computer software for linux

Yet Another Free PDF-composer can compose PDF documents from picture files and other PDF files, encrypt the created document, and send it to a given email address.
Imagine you need a PDF-printer-like tool, which is able to generate PDF-files from documents, you want print out of your applications on your local machine.
There are plenty of solutions out there on the web, which can do this for you. Now imagine you need a PDF-printer to be shared in your network, which is able to generate PDF-files from documents, the network users print out of their applications.
Youll find some free solutions, which can make this. Further imagine, you want this PDF-printer automatically to apply the letterhead template of your company to the first page, apply the company-logo to all further pages, append a "Terms and Conditions" page to all printed documents, apply some "Watermark Graphic" on all pages to copy-protect your documents, encrypt the document to protect it from unwanted manipulation and automatically mail the document to the user, who initiated the print-job.
Hard to find a free solution on the web, which can do this for you.
Enhancements:
- This is a general code cleanup and feature enhancement release.
- YAFPC uses iText 1.4.4 now and requires Java 1.5 or above.
- Feature enhancements include a large variety of encryption settings, explicit settings for owner and user passwords, and enhanced processing of paper sizes and orientations.

kearone provides icon pack for gnome based on my "kearones icons"
Version restrictions:
- think it could be improved with a more consistent Computer icon, and some black contour around the file type icons (just like the Home and Trash).

CheeseTracker is a software sampler and step-based sequencer. It allows a musician to turn single-note samples into instruments capable of covering three or four octaves (by playing the samples at different speeds, resulting in different pitches). In addition, it is possible to take a collection of samples that are recorded at different octaves, and combine them into a single "instrument," allowing for even more octaves without sampling artifacts.
Using the Pattern Editor, it is possible to compose songs with these instruments that the computer plays automatically. The Pattern Editor allows the user to arrange samples in several independant channels, so that many samples can play simultaneously. These songs, and the samples which comprise their instruments, can be saved together in one-file archives called modules.
CheeseTracker imposes no limits on the length of the samples used. As a result, it can be used as a mixer as well as a sampler/sequencer. Effects such as reverb can be applied to each sample individually, eliminating the need for expensive pedals.
It is distributed under the terms of the GNU General Public License.
CheeseTracker is modeled after a DOS-based freeware program called Impulse Tracker (which has been abandonware since the late 1990s). It is mostly compatible with Impulse Tracker, being able to load Impulse Tracker files.
Main features:
- Unlimited sample size
- Keymaps: Build instruments that use a range of samples, just like a hardware sampler.
- LADSPA sound effect filters with near-analog quality
- Built-in effect filters:
- Amplifier
- Reverb
- Stereo Chorus
- Echo
- Equalizers: 6, 10, 21, and 31 bands
- Distortion
- Pitch Shift
- Effect filters can be combined.
- Up to 64 simultaneous voices
- Volume, pan, and pitch envelopes with sustain loop
- Built-in sample editor
- Sample loops with forward and ping-pong modes
- Compatible with JACK, ALSA, and OSS audio architectures
- Most functions are accessible from the keyboard
- Plays samples at different pitches to create notes
- Simulated live musical keyboard (using a QWERTY keyboard) can play alongside programmed songs

Open Computer Forensics Architecture (OCFA) is a modular computer forensics framework built by the Dutch National Police Agency. The main goal is to automate the digital forensic process to speed up the investigation and give tactical investigators direct access to the seized data through an easy to use search and browse interface.
The architecture forms an environment where existing forensic tools and libraries can be easily plugged into the architecture and can thus be made part of the recursive extraction of data and metadata from digital evidence.
The Open Computer Forensics Architecture aims to be highly modular, robust, fault tolerant, recursive and scalable in order to be usable in large investigations that spawn numerous terabytes of evidence data and covers hundreds of evidence items.
Enhancements:
- This release fixes a memory leak in the evidence library and adds a workaround to limit the impact of a memory-hungry indexer module.

Computer Temperature Monitor is a little applet for the GNOME desktop that shows the temperature of your computer CPU and disks on screen. Computer Temperature Monitor also allows you to log temperatures to a file.
You can set alarms to notify you when a tempertature is reached. Several monitors can be added to the panel to monitor different sensors. It is designed to look like the CPU Frequency Gnome applet. This applet used to be called Laptop Temperature Monitor.
Enhancements:
- The way the temperature file is read has been changed to fix a bug in some modules (acpi, ibm_acpi, i8k, and omnibook).
- Support has been added for Apple G5 computers (windfarm sensors).
- Support has been added for dynamic log filenames using patterns.
- A bug that prevented the icon from appearing sometimes has been fixed.
- A GConf key has been added for showing debug information in the applet tooltip.
- A Simplified Chinese translation has been added.
- Support has been added to change the logging timeout.
- There are some bugfixes.
