hungrycat is a tool that prints the contents of a file on the standard output while simultaneously freeing disk space occupied by the file. It can be useful if you need to process a large file, but you don't have enough space to store the output file, and you won't need the input file afterward.
libtld is a library used to extract the TLD from a URI and to check email validity. This allows you to extract the exact domain name, sub-domains, and all the TLD (top level, second level, third level, etc.). The problem with TLDs is that you cannot know where the domain starts. Some domains can use one top-level domain, others use two, etc. However, it may be useful to know where the domain is to have the exact list of sub-domains. For example, if you want to force www. at the start of the domain name if no other sub-domains are specified, then you need to know exactly how many TLD are defined in a URI. The libtld offers one main function: tld(), which gives you a way to extract the TLD from any URI. The result is the offset where the TLD starts. This gives you enough information to extract everything else you need. For emails, the library is capable of parsing a string that represents a list of email addresses to be verified. The verification includes a check of the domain name and its TLD.
ZShaolin installs a powerful terminal on your Android device, without requiring root. It comes with applications to edit text, images, audio, and video using shell scripts and programs like FFMpeg, ImageMagick, Sox, Oggz, Lua, awk, sed, vim, emacs, git, SSH, and rsync. A zsh command line environment comes pre-configured with colors, smart completion, error correction, and all man pages, making ZShaolin also suitable for those who would like to learn shell scripting and Unix system administration via a remote session.
The X3D library is used to load an X3D file and render it using OpenGL (an X3D file is an XML file describing a 3D environment that can be rendered with OpenGL.) The library supports all the objects as defined in the X3D specification in 2006. The render library is still somewhat limited, though. It works well under Linux. It is likely to work on any Unix, and has worked under MS Windows before. The project includes a test that makes use of FLTK version 2.0-m3. That version of FLTK can be downloaded from the project repository, as FLTK itself actually ended up not publishing a concrete 2.0 version of the library.
BACnet is an implementation of the BACnet (Building Automation and Control Networks) protocol specifically tailored for embedded systems. BACnet itself is a standard routable protocol designed to handle communications in automation in buildings, such as air conditioning systems and other HVAC equipment.
