Chordpack is a tool written in Perl, whose purpose is to typeset song-books/songs written in chordpro format. The typesetting is done through typesetting system TeX using macro package LaTeX. Chordpack was created to do whatever you might want to do with songs in chordpro format. Chordpack currently can
Generate LaTeX source of songs/songbook
Generate HTML version of songs/songbook
Generate ASCII version of songs/songbook
Generate ASCII version of songs/songbook omitting chords
Transpose chordpro song to desired key
Take ordinary ASCII notation of song with chords and output almost chordpro version.
Enhancements:
- four styles of chord setting
- three styles of song titles setting
- option to chose one or two columns
- option to chose fonts sizes
- on-the-fly transposition to a key with minimum diffic

Fityk project is a general-purpose nonlinear curve fitting and data analysis software.
Although it is being developed to analyze powder diffraction patterns, it can be used to fit analytical functions to any kind of data: crystallographic module is an independent part of the program. Apart from crystallography fityk is reported to be used also in chromatography, photoluminescence, infrared and Raman spectroscopy, and in other fields.
At present fityk knows only about common peak-shaped functions (Gaussian, Lorentzian, Voigt, Pearson VII etc.) and polynomial. User-defined functions will be implemented in 2005.
In terms of powder diffraction fityk will fit the data with a set of position-correlated peaks to give the refined lattice parameters, zero-shift, sample displacement and wavelength.
Fityk offers everything a decent refinement program should offer but first of all intuitive graphical interface. Apart from the standard Marquardt least-square algorithm one may choose a genetic algorithm or Nelder-Mead simplex method for complex or unstable cases.
Fityk already works under Linux, Windows and MacOS X and can in principle be ported to other systems because its GUI is written with a portable wxWidgets library. And it is free software (GPL).
Main features:
- It is the heart of the program - finding minimum of weigthed sum of squared residuals, in other words - fitting function to data. Nonlinear fitting is a difficult problem, and there is no perfect solution. Fityk offers three well-known algorithms: Levenberg-Marquard gradient-based method, Nelder-Mead downhill simplex method and Genetic Algorithms. Every of these methods has a set of adjustable parameters, for greater flexibility.
- Data - a set of (x, y) points, can be read from text file, or from file in one of other supported formats. When loading data, you can read standard deviations of y s, if given, read only selected points (eg. first thousend, or every third point) or merge neighbouring points, to reduce noise. In every moment you can activate or disactivate selected points (disactivated points are not subject to fitting) or change standard deviation.
- Fitted curve is given as a sum of functions. All functions are given by parametrized formulae, eg. function of gaussian type has such parameters like height or position of center. Availaible functions are: gaussian, lorenzian, pearson VII, voigt, pseudo-voigt and fifth-order polynomial.
- Every parameter of function is given as a constans or as a variable or as a function of other parameters. First case is clear. In second case value of the variable can be adjusted when fitting. Optionally also domain of the variable can be given. In last case, the parameter can be given in terms of other parameters, eg. as a multiplication of constant and variable parameters.
- Background (baseline) may be obtained as linear or spline interpolation of points selected by the user or as a background function, that optionally can be fitted. Currently the only function suitable for background is a polynomial.
- There are two ways of dealing with error in x s. First requires specifying displacements of x in points, where it is known - program will interpolate it to the rest of points. Second assumes that the source of displacements is known and given by a zero-shift functions, which can be fitted.
- All commands, that are changing anything, what can influence further run of the program (eg. adding baseline, but not displaying help), can be logged to file. This is one of the ways to obtain a script, that can be edited and reused. Using scripts can save a lot of work, eg. it is possible to write scripts that will fit a series of data files and output results.
- The crystallographic module of the program enables easy adding peaks, that represents Bragg reflections. It is assumed that analyzed data points are intensities in function of 2theta, typically from X-ray diffraction. User have to define phases (lattice parameters), wavelengths with their relative intensities and which hkl s are present. Optionally, width and shape parameters can be constrained, using formulae taken from DBWS program.
- Fityk is written in C++. The program (GUI) can run on most Unix species with GTK+, on MS Windows and MacOS X. Ports to other platforms supported by wxWidgets library are also possible.
- The program comes in two versions: GUI (Graphical User Interface) version - more comfortable in most cases, and CLI (Command Line Interface) version (named cfityk to differentiate) - used only in special situations, when visualisation is not essential and user prefers to use a text terminal.
- There is a mailing list where everyone can ask a question. You can also write directly to programs author, although usually its better to use the mailing list. Asking for a change in fityk or for new feature will usually result in putting the request on TODO list or, if it is already on TODO list, in assigning higher priority to it.
- It is free software; you can redistribute and modify it under the terms of GNU General Public License. There is NO warranty.
Enhancements:
- The Shirley background correction procedure was implemented.
- A few bugs were fixed.

Libundo is a simple, easy-to-use library which manages recording and playback of undo/redo information for application developers.
It is designed to be simple to plug in to existing applications and require only a minimal amount of support code be written to support multi-level undo/redo.
Libundo handles all the details of determining what has changed after an undoable action is performed, recording that information and saving it for use when an undo is performed.
Libundo makes it easy for application writers to give end users what they want.
Libundo is available under the GNU GPL and is not tied to any GUI libraries or application frameworks. Libundo has a C language interface.
Enhancements:
- Fixed a serious bug, when allocation of a large chunk (larger than the page size) after an undo operation would corrupt the memory. The bug was introduced in 0.8.1.

- Easy, simple an eye-candy view of an online comic
- Browsing over the comic strip archives
- Saving a comic to disk

Scratchy is a set of scripts to parse Apache web server log files and extract useful information. From this data, Scratchy will create HTML reports so that website administrators can easily view the information and determine trends and their typical audience.
Scratchy began as a proof-of-concept which allowed me to compile stats about my personal website. As time progressed I continually added features and improvements and I felt that it would be useful to others.
The functionality that the project aims to supply is a complete log parsing and report generating tool. Also, there seemed to be a need for such a project in Python. I have seen some other Apache log parsers but they were developed in other languages (such as Perl, C, etc). One goal of this project is for it to be extensible, to that tune, most of the report appearance can be easily modified by tweaking a single config file.
What information does Scratchy report?
- Accessed web pages
- Hosts accessing your website
- Operating systems
- Browsers and versions
- Search engines
- Robots
- File types accessed
- Errors
- Country name lookups (if enabled).
- Charts of most data (if enabled).
- A trace of pages accessed by each ip address (if enabled).
Enhancements:
- Migration from pickled dictionaries to SQL database (MySQL)
- Deprecated gdchart in favor of ChartDirector $nbsp;
- Deprecated http country lookups in favor of GeoIP API
- Code optimizations
- Additional user agents
- Major version change - the pre 0.8 data is no longer supported. You must re-parse all logs. Sorry.
