Mac ChiSquare Analysis 2.1
Mac ChiSquare Analysis - Chi-square, phi, contingency coeff., kappa more>>
Mac ChiSquare Analysis calculates chi-square statistic as well as phi, contingency, and kappa coefficients from up to a 10 x 10 table.
The chi-square test is used to compare the distributions of two independent samples. It is used with data in the form of frequencies. It is a nonparametric procedure that makes no assumptions about distribution shapes, variances, or levels of measurement (Diekhoff, 1996).
The chi-square test evaluates the correspondence between the expected and the observed number of cases in each of the cells of the variable by variable contingency table (Thompson, 1988). It is a test of whether or not a null hypothesis of no association should be rejected between the two independent variables.
If the chi-square test shows that there is a relationship between the two variables, then the contingency coefficient gives an indication of the degree of the relationship. (Bruning & Kintz, 1997). The contingency coefficient is similar in meaning to the correlation coefficient.
Cramers phi coefficient is a measure of association that is also similar to a correlation coefficient. It can assume a value between 0 and +1. See Sheskin (2000) for further detail.
Kappa is calculated when the rows and columns are symmetrical. Kappa is often used to examine inter-observer agreement and reflects the amount of agreement beyond chance (Norman & Streiner, 2000).

Cynthiune 0.9.5
Cynthiune is a free software and romantic music player for GNUstep and Mac OS X more>>
Cynthiune is a free software and romantic music player for GNUstep and Mac OS X. Cynthiune can play Ogg and MP3 files.
For the moment, it looks pretty much like XMMS, Winamp and similar software. Even though it has far less features than those, the essential components of a usable and user-friendly program are there in my opinion.
From a programmatic point-of-view, I have decided to write a program that is released only when considered bug-free. The free software community lacks, IMnsHO, a sense of quality that makes its programs nearly useless to lambda users. Not only is it useless, but I think it also gives free software a bad reputation. The principle of freedom in "free software" is fundamental to me, but it has to be reachable not only by some sort of geeky elite. There is no point in telling users that since they have the freedom to enhance those programs, they must fix them if they want to use them. Releasing a program with too many bugs is of no use and is likely not to interest other fellow programmers in the community either.
On the other hand, Apple has published an interesting program called "iTunes". Of course, it is not free software but it does implement interesting ideas that I would like to include in Cynthiune. For example: CD burning, complete playlist management, etc... Personally I find its user interface to be not as user-friendly as it could be. My plan is thus to take advantage of my own programming skills and sense of aesthetics (and ergonomy) to try to write something a little bit different, inspired both by XMMS/Winamp and iTunes. Cynthiune is thus currently very basic but its core design is starting to be extensible enough that it will not be too much trouble to enhance it.
Enhancements:
- Major feature enhancements.

Gambit-C 4.1.2
Gambit-C is such a great program including a Scheme interpreter and a Scheme compiler which can be used to build standalone executables. more>>
Gambit-C 4.1.2 is such a great program including a Scheme interpreter and a Scheme compiler which can be used to build standalone executables. Because the compiler generates portable C code it is fairly easy to port to any platform with a decent C compiler. The thread system is very efficient and can support millions of concurrent processes.
The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme standards. The full numeric tower is implemented, including: infinite precision integers (bignums), rationals, inexact reals (floating point numbers), and complex numbers.
Major Features:
- Conformance. The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme standards and implements all optional features. Tail calls and first class continuations conform to the Scheme semantics. The full numeric tower is implemented, including: arbitrary precision integers (bignums), rationals, inexact reals (floating point numbers), and complex numbers. Several extensions to Scheme are provided, including: lightweight threads, a foreign-function interface (FFI), and extended I/O capabilities (Unicode, networking, subprocesses, ...).
- Portability. Because the system is mostly written in Scheme and the compiler generates portable C code, it is easy to port the system as well as programs compiled with it to any platform with a decent C or C++ compiler. There is no reliance on a particular C compiler, although the system can take advantage of some gcc-specific constructs. The C code generated is oblivious to the endianness and word size of the target environment (32 and 64 bit architectures are currently supported).
- Performance. The compiler includes several powerful program transformations such as user procedure inlining, partial-evaluation, and lambda-lifting. With appropriate declarations in the source code the executable programs generated by the compiler run roughly as fast as equivalent C programs. Programs containing no declarations are also optimized without compromising the Scheme semantics by speculatively inlining predefined procedures. Thanks to an efficient implementation of continuations, the thread system is very efficient and can support millions of concurrent threads. The bignum library uses sophisticated algorithms that are in some cases asymptotically faster than those of GMP (GNU Multiple Precision Arithmetic Library). [Note: With the release of GMP 4.3.0 in April 2009, this claim is no longer true; ]
- Reliability. Stable releases typically have very few bugs. Bug tracking is done with bugzilla. Gambit-C has been used to develop large-scale real-world software in academic and commercial settings.
- Mac OS X 10.3 or later.

RumLog 4.2.3 comes to you as a free logging, QSL handling and printing tool, which is especially designed for the short wave DXer, made by a DXer. Basic logging features are included for the higher bands up to 1.2 cm. RUMlog can handle an unlimited numbers of logs and an unlimited numbers of QSOs per log. An user editable, all time country database is used for automatic DXCC recognition.
Major Features:
- RUMlog includes routines, tables and an interactive gray line map to support the user in gray line dxing.
- Using RUMlog you can print QSL card labels and manage your incoming paper QSLs. The Logbook of The World (LoTW) and eQSL are fully supported, and you can create files for the Global QSL service very quick. You can get different statistics for paper- or LoTW QSLs. It's just a mouse click to upload or download new QSLs to/from eQSL or LoTW.
- RUMlog can use the ON6DP QSL manager database to inform you about managers or addresses and it can build and use an own manager and IOTA database, extracting the information from dx-cluster spots. Provisions are made to query the qrz.com online library.
- RUMlog keeps you up to date about worked, confirmed or missing DXCCs and provides you with country lists and detailed statistics. Quick log searches or more detailed log queries are possible.
- RUMlog can establish a dx-cluster connection via the internet or via packet radio. A simple terminal is integrated for a Packet Radio connection. RUMlog will separate DX-spots and alert you via e-mail or Growl when there is a ,new one' DXCC or IOTA spotted. Multiple interactive band maps virtualize activities on the air.
- RUMlog can interface with two transceivers, setting the main parameter on your TRX from the logbook or vice versa. Kenwood, Elecraft, Yaesu and Icom transceivers are supported.
- RUMlog has import and export functions to allow exchange of log data in different formats to other logging tools.
- RUMlog can interface with Google Maps (Web-Browser based) and Google Earth. (Must be installed on your computer)
