Free for mac os x software for linux

Murrina-Brown 0.1 is yet another great addition for Gnome users. It is actually a port of Mac OS X theme, Muku v1.2. The dock on the bottom is avant-window-navigator. Emerald theme is included.

LightBlue is a cross-platform Python Bluetooth API. It is available for Mac OS X, GNU/Linux and Nokias Python for Series 60 platform for mobile phones.
Main features:
- Device and service discovery (with and without end-user GUIs)
- Standard socket interface for RFCOMM sockets
- Sending and receiving files over OBEX
- Advertising of RFCOMM and OBEX services
- Local device information
Version restrictions:
- findservices() and selectservice() on Python For Series 60 returns only RFCOMM and OBEX services
- Avoid threading on Mac OS X, as the underlying IOBluetooth and IOBluetoothUI frameworks are not thread-safe
- No cross-platform set of socket options
- Sockets (the native PyS60 API sockets are used, so their restrictions are inherited - but I havent used PyS60 1.3.8 yet so Im not sure about that)
- sockets on Python For Series 60 cannot be created in one thread and used in another
- fileno() raises NotImplementedError on Mac OS X and Python For Series 60
- timeouts not supported on Python For Series 60: settimeout() raises NotImplementedError, gettimeout() returns None
- non-blocking mode on PyS60 works for send() and recv but not accept() or connect()
- No socket options on Mac OS X, and flags arguments (e.g. for recv) have no effect
- socket security cannot be set (PyS60 implementation sets this to AUTH by default)
- Error codes for exceptions are platform-independent. In particular, the Mac OS X implementation can return IOReturn error values from the IOKit framework, and OBEXError codes from < IOBluetooth/OBEX.h > for OBEX operations.
Enhancements:
- The PyS60 3rd Edition binaries have (really) been fixed, and gethostaddr() and gethostclass() should also be fixed for PyS60 2nd Edition FP2 and FP3.
- Since its getting more difficult to build for PyS60 1st Edition, this build has been dropped for this version -- which isnt an issue for this release since there are no new features -- but there wont be any further builds for this edition. If you need to compile LightBlue for 1st Edition, feel free to email me with any issues.
- Fixed functions on Mac OS X build that wait (e.g. finddevices(), recv() for sockets) so that they dont busy-wait and hog the CPU.

EiffelStudio is the complete Eiffel development platform for Linux/Unix/Windows/Mac OS X.

EiffelStudio is a complete development environment for the Eiffel programming language. It includes a compiler, an interactive debugger, and many modern features like a full round-trip class diagram editor or refactoring support. Eiffel is compiled through C to produce very fast executables.

EiffelStudio is highly portable and supports Linux, Microsoft Windows, Mac OS X, most flavors of Unix, and even VMS or embedded environments. Portability of applications is supported by a large set of portable libraries, including: EiffelBase (data structure), EiffelNet (network), EiffelVision (native GUI), EiffelStore (database access), EiffelParse (parsing), Gobo (XML), EiffelWeb (Web), EiffelCOM (COM), and many more.

SQL Relay is a persistent database connection pooling, proxying and load balancing system for Unix and Linux.
Main features:
SQL Relay is ideal for:
- speeding up database-driven web-based applications
- enhancing the scalability of database-driven web-based applications
- distributing access to replicated databases
- throttling database access
- accessing databases from unsupported platforms
- migrating applications from one database to another
SQL Relay supports the following database backends:
- Oracle
- MySQL
- mSQL
- PostgreSQL
- Sybase
- MS SQL Server
- IBM DB2
- Interbase
- Sybase
- SQLite
- ODBC
- MS Access
The SQL Relay client APIs support advanced database operations such as bind variables, multi-row fetches, client-side result set caching and suspended transactions. SQL Relay has native client APIs for the following languages:
- C
- C++
- Perl
- Python
- PHP
- Ruby
- Java
- TCL
- Zope
SQL Relay provides drivers for the following database abstraction layers:
- Perl DBD
- Python DB
- Ruby DBD
- PHP Pear DB
An application coded using another databases native client API may be able to use SQL Relay without modification. SQL Relay provides drop-in replacement libraries for:
- MySQL
- PostgreSQL
SQL Relay also features:
- command line clients
- a GUI configuration tool
- extensive documentation
Enhancements:
- Several contributed patches were applied.
- Oracle stability was improved.
- Support for Oracle OS-authentication was added.
- The maxlisteners option was added.
- Support for Sybase stored procedures which return result sets was added.
- A Zope empty-result set bug was fixed.
- Support for Mac OS X, Solaris, and Cygwin was improved.
