trillbox is a flexible and extendable toolkit for building dynamic Web pages. Written in Perl and based on Template::Recall, it provides "widgets" (or controls) that you can quickly integrate into your Perl Web application. trillbox widgets are designed to be independent points of control that can be easily plugged into a Web programming system, e.g. a CGI application, template-based, or included as part of an application framework. Widgets purposely have no direct knowledge of each other in order to offer the greatest flexibility (although they may be designed so that output and input can be piped between widgets).
Twapake is a system administration utility for Slackware and Slackware-based operating systems only, making it easier to manage last installed packages and see the installation date of a package. It can print a simple list of N packages sorted by installed date to STDOUT. It can print a snapshot logfile to the /var/log/twapake/ directory. A snapshot is a list of all packages sorted by installed date at T time. The installed date is printed too, making it easier to see when a package has been installed on your system. You can remove the last N installed packages, print the packages installed since a chosen date, and launch a Curses User Interface for easy removal.
