SmbSync is a program to move files between Unix and Windows shares directly, avoiding the need for mounts or extra services like FTP or Rsync. It uses input and output directories, and can be configured to handle many directories and servers. It can retry uploads and downloads that fail, avoids incomplete file transfers, does not touch recently modified files with a configurable timeout, can archive files instead of deleting files transferred, can upload or download to temporary directories so that scripts that trigger on the files will only see complete files, and allows you to configure blocksize.
sqlzma is a patch against lzma and squashfs that makes squashfs support both LZMA compression and ZLIB compression. A squashfs image file that uses LZMA compression has no backward compatibility, but the patched squashfs and its tools can handle the old squashfs image generated by the unpatched squashfs-tools.
m9u is a music server, similar to mpd or xmms2. It sits in the background, waiting for commands to be delivered via a 9p file system. m9u embraces the Unix philosophy of doing one thing well. As such, it does not try to catalog or otherwise organize music, but aims for the more humble goal of simply playing it. A side effect of this approach is that m9u is trivially extensible to domains aside from music (for example, an image slideshow).
JImageExplore is an image viewer with features to make navigating image archives simple. It extends JImageView, which is a plain image viewer, and adds a way to navigate directories and archive files. Thanks to TrueZIP, archive files are treated as virtual directories. JImage Explore also adds support for docking windows which will be used for supporting extensions such as multiple image display and thumbnail views.
