NScripts is a set of Nautilus scripts for several purposes, like changing the background and the splash image, copying and moving files (similar to Konqueror's context menu actions), creating and checking MD5 sums, creating a diff of two selected files, sending shortcuts to any place, creating menu entries from .desktop files, opening all selected files in GEdit, opening a terminal with the current directory as the working directory, and shredding files.
The Monkeysphere enables you to use the OpenPGP web of trust to verify ssh connections. SSH key-based authentication is tried-and-true, but it lacks a true public key infrastructure for key certification, revocation, and expiration. Monkeysphere is a framework that uses the OpenPGP web of trust for these PKI functions. It can be used in both directions: for users to get validated host keys, and for hosts to authenticate users.
vzhaipd (scoyo's Virtuozzo/OpenVZ HA IP Daemon) is a set of mount/umount Container scripts for Parallels Virtuozzo or OpenVZ that will make sure a HA IP is always present on one of two or more Containers. You can think of it as the poor man's VRRP for Virtuozzo and OpenVZ Containers. Use it for general service availability, software load-balancer failover, etc.
grindr is a set of various utilities to enhance Web productivity. It provides tools to interact with Web sites, RSS feeds, and instant messaging. Munchr is a simple RSS parser which can collect data from restricted Web sites, and this data is routed to nbox. nbox is a small GUI display for all collected information. Posting information is done by feedr, which takes a set of parameters and values and submits it to the appropriate Web service. gaskr provides a GUI to prepare data for feedr. Initial configuration for gaskr is prepared by bildr, which can log onto sites and scrape all form data from HTML content.
Bashrun provides a powerful application launcher by running a specialized bash session in a small terminal window, conveniently providing bash features like tab completion and history. Additional features include user-configurable rules for automatically launching certain commands in a new terminal window, looking up manual and info pages, performing dict and Google queries, defining bookmarks for Web pages, or piping command output to the clipboard. Users can add more functionality by defining arbitrary rules for rewriting command lines based on regular expression matches and file test operators. This makes new features like file associations or Web shortcuts trivial to implement.
