gtranscode is a GTK+ GUI (graphical use interface) front-end for transcode written in order to make this powerful tool easier to use. Transcode is a powerful video and audio processing tool that can read in just about any format of video and/or audio and convert to just as many different formats. In addition to transcodes extremely flexible modular concept for reading/writing different formats and codecs, it can apply filters, do re-sampling, resizing, cropping, and more. The cost from all this comes in the form of over 100 command line options but gtranscode aims to simplify.
Main features:
- organized layout to reduce confusion
- supports all of the options that most users will want
- uses tcprobe -i (from transcode package) to summarize information about input file before processing
- shows the equivalent transcode command line for troubleshooting and familiarizing users with command line options
- any extra options not supported by the GUI can be manually entered in the entry box before hitting "GO"
- automatic "maintain aspect ratio" calculations
- automatic "projected filesize" calculations based on bitrates
Enhancements:
- added much needed cancel button to progress window
- added capability to tcprobe an entire directory and add the number of frames up. This allows a directory to be transcoded without the progress bar saying NaN.

Bristol is an emulator for diverse existing synthesisers and organs. Currently, ten are implemented and a mixer is under development.
Bristol Audio software consists of an audio engine and an associated photo realistic graphical user interface called Brighton.
You may also want to chown/chmod bin/bristolengine to suid root, to allow it to use low latency scheduling. This will reduce audio underruns. You can also consider increasing bufsize and preload to reduce this effect, but this will lead to increased latency. Also, if you are using an SB Live! card with ALSA drivers you may need to configure a bufsize of 2048 (ie. 512 samples), which can be compensated for by reducing preload to 2 or 1.
Bristol will currently run 16 voices on a P-II 450, and this is the default voicecount. You can run any number of simultaneous synths - they all connect to the same engine, they will all run with the same polyphony since the MIDI voice structures allow for dynamic assignment of sounds to voices. You can run with split keyboard (no interface at the moment), layering of multiple synths on a single midi channel, etc. Some of the synths max out my P-II 450 CPU when there is a lot of MIDI activity, notably the DX and Explorer at 16 voices.
You can start different synths with different voicecounts, so you could have a 16 voice hammond, a monophonic minimoog, and a 5 voice prophet running at the same time - the GUI will negotiate the voice allocation requirements with the engine. The first synth you start will create the voice count. Subequent synths can have less than the initial value. If you start a monophonic synth first, you will only have one voice available at any time for all synths. If you layer synths you will reduce your polyphony since the engine will allocate multiple voices per keyed note.
Pressing the single letter q in the GUI will send a quit signal and the app will exit gracefully(?). When the last synths quits the engine will also exit. If you press the single letter p then libbrighton will dump a screenshot to /tmp/ .xpm (in XPM format only).
There is a LOT of debugging sent to stdout. You may want to consider adding redirects to /dev/null in the bin/startBristol script to get rid of it. When the final rev-1 is uploaded most of this will be taken out.
Enhancements:
- The graphics were cleaned up, some bugs were fixed, and work on a pair of Oberheim emulators was started.

OSSP ex is a small ISO-C++ style exception handling library for use in the ISO-C language. It allows you to use the paradigm of throwing and catching exceptions in order to reduce the amount of error handling code without making your program less robust.

This is achieved by directly transferring exceptional return codes (and the program control flow) from the location where the exception is raised (throw point) to the location where it is handled (catch point) -- usually from a deeply nested sub-routine to a parent routine.

All intermediate routines no longer have to make sure that the exceptional return codes from sub-routines are correctly passed back to the parent.

The OSSP ex facility also provides advanced exception handling features like shielded and deferred exceptions. Additionally, OSSP ex allows you to choose the used underlying machine context switching facility and optionally support multi-threading environments by allowing you to store the exception catching stack in a thread-safe way.

Dir::Purge is a Perl module to purge directories to a given number of files.

SYNOPSIS

perl -MDir::Purge -e purgedir (5, @ARGV) /spare/backups

use Dir::Purge;
purgedir ({keep => 5, strategy => "by_age", verbose => 1}, "/spare/backups");

use Dir::Purge qw(purgedir_by_age);
purgedir_by_age (5, "/spare/backups");

Dir::Purge implements functions to reduce the number of files in a directory according to a strategy. It currently provides one strategy: removal of files by age.

By default, the module exports one user subroutine: purgedir.

The first argument of purgedir should either be an integer, indicating the number of files to keep in each of the directories, or a reference to a hash with options. In either case, a value for the number of files to keep is mandatory.
The other arguments are the names of the directories that must be purged. Note that this process is not recursive. Also, hidden files (name starts with a .) and non-plain files (e.g., directories, symbolic links) are not taken into account.

All directory arguments and options are checked before anything else is done. In particular, all arguments should point to existing directories and the program must have read, write, and search (execute) access to the directories.

One additional function, purgedir_by_age, can be exported on demand, or called by its fully qualified name. purgedir_by_age calls purgedir with the "by age" purge strategy preselected. Since this happens to be the default strategy for purgedir, calling purgedir_by_age is roughly equivalent to calling purgedir.

Quake III Arena Cell Shadings goal is to add Cell Shading capabilities to the Quake III engine with Real-time performance.

In order to provide such feature we have decided to use Kuwahara filter. Kuwahara filter is a noise-reduction filter that preserves edges.

It uses four subquadrants to calculate the mean and variance and chooses the mean value for the region with the smallest variance.

To increase the hand-painted effect we have decided to apply a simple blur filter to reduce hard-edges on textures and increase the flatness effect.

To produce the cell shading edege effect we use no gfx card shaders, so our implementation could run with almost any gfx card. This effect is produced by painting backface polygons with a thick wireframe without textures and repaint all the scene, but this time, with textures.

To test our modified engine just place our binary in your games folder to frag all day long!

Ensure you have a copy of Quake 3 Arena installed on your PC. Youre going to need the artwork/content from the game because it is not redistributable.

FLAC is a lossless compression method for audio files. Using it, one is able to reduce the filesize and keep the same audio quality as a regular WAV file (CD quality).

The FLAC format is open source, and can be read without any problem by such applications as Amarok or Kaffeine.

Wav and Flac conversion contains two service menus: one to convert WAV files into FLAC, and one to convert FLAC files into WAV.

You will need the FLAC application to be installed on your system to use these service menus.

Jhead is a command line driven utility for extracting digital camera settings from the Exif format files used by many digital cameras. It handles the various confusing ways these can be expressed, and displays them as F-stop, shutter speed, etc.
Jhead project is also able to reduce the size of digital camera JPEGs without loss of information, by deleting integral thumbnails that digital cameras put into the Exif header. If you need to add Exif support to a program, this is a simple program to cut and paste from. Many projects, including PHP, have reused code from this utility.
Things jhead can extract from an Exif jpeg file:
- Integral low-res Exif thumbnail
- Shutter speed
- Camera F-stop number
- Flash used (yes/no)
- Distance camera was focused at
- Focal length and calculate 35 mm equivalent focal length
- Image resolution
- Time and date picture was taken
- Camera make and model
Things jhead can modify in an exif jpeg file:
- Up-right images according to rotation tag using jpegtran
- Set or relative adjust internal exif timestamps
- Re-name or date stamp fils according to exif timestamp
- Transfer exif headers between images
- Edit jpeg comments
- Delete exif or comment sections from jpeg images
Enhancements:
- The "-mkexif" option to create a new minimal EXIF section in an existing image was added.
- The "-ds" and "-dsft" options to manipulate the EXIF date and time were added.
- Image and thumbnail rotation flag handling was fixed.
