AlmostVPN is an SSH tunnel manager with a twist. It is packaged as a Preference Panel, so you do not have to use yet another application to configure your tunnels. Instead, it uses creative network configuration techniques to provide almost VPN-like access to remote services, so you can keep using real IP addresses and port numbers while accessing service on the other side of your tunnels. It provides a simple way to mount remote volumes, use remote printers and faxes, access iTunes, iPhoto, and almost any other Bonjour-based application, transfer and execute files, and more.
Fugu SSH is a Mac OS X graphical frontend to OpenSSH's Secure File Transfer application (SFTP). SFTP is similar to FTP, but, unlike FTP, the entire session is encrypted, meaning no passwords are sent in cleartext form, and it is thus much less vulnerable to third-party interception. Fugu allows you to take advantage of SFTP's security without having to sacrifice the ease of use found in a GUI. Fugu also includes support for SCP files transfers, and the ability to create secure tunnels through SSH.
GNUSTEP Live CD contains a lot of software for GNUstep, a free implementation of the OPENSTEP framework (which is also directly used in Mac OS X as Cocoa). It includes excellent applications for RAD (GORM and ProjectCenter). The CD is available for i486, AMD64, Apple Mac PowerPC, and Sun UltraSPARC computers.
GPP is a general-purpose preprocessor with customizable syntax, suitable for a wide range of preprocessing tasks. Its independence from any programming language makes it much more versatile than cpp, while its syntax is lighter and more flexible than that of m4. The syntax is fully customizable, which makes it possible to process text files, HTML, or source code equally efficiently in a variety of languages.
Green Dome GNUstepWeb for Mac OS X provides a WebObjects 4.5-like environment for Mac OS X (with some support for WO5 additions). It is composed of modified versions of the standard GNUstepBaseAdditions, GDL2, and GNUstepWeb frameworks, built to run on top of Apple's Cocoa frameworks. The GNUstep frameworks have been built with Xcode as true Mac OS X frameworks. Thus, they may be used as any other framework under Mac OS X. Note that this is a standalone package that does not require or interoperate with a separate GNUstep installation/environment. It is not intended to provide a complete GNUstep environment, such as would be expected of a full GNUstep installation.
