'Showcase', and 'Polymon'

Showcase

Showcase provides a new way to manage your Firefox tabs and windows by showing them as thumbnails in a single window, tab or sidebar. Showcase includes a find bar that will filter the thumbnails, and the capability to select the thumbnails in the same way you would select files in your system.

Polymon

PolyMon is an open source system monitoring solution that can be used to generate email alerts and analyze historical trends. It is made up of three primary components: A SQL Server database to store monitor statuses, alerts and general settings. Email notifications are handled by a stored procedure in the database itself. A windows service (PolyMon Executive) that runs monitors on a periodic basis and logs results to the database. A management/monitoring front-end (PolyMon Manager) that is used to manage general settings, monitor definitions, operators, alert rules, etc. and analyze historical trends (both monitor counters and statuses). Currently included monitors are: Ping, Performance Monitor, SNMP, URL, File (Age and Counts), Windows Service, SQL Monitor (Can run any stored procedure that returns results in a specific format), TCP Port Monitor. Monitors are built using a plug-in architecture and can be added to PolyMon without requiring a recompile of the application. New plug-ins simply need to inherit from a base class.
