jBoom is a program for remote storage and management of browser bookmarks and mail addresses. It allows accessing a central set of bookmarks and addresse from any system connected to the Internet. It is browser, mailer, and system independent, not bound to a dedicated server, and doesn't require a special Web service. The bookmarks are kept in an XML file on the remote system. A local copy can be stored on the client. The program may be started from the client or over the Internet from an HTTP server. Entries can be activated from the main window or the system tray.
Pactester is a tool to test proxy auto-configuration (PAC) files. PAC files are used by browsers to identify the correct proxy server for a given URL. Since the PAC file evaluation mechanism is generated inside the browser and cannot be accessed from outside, the only way to tell which proxy your browser will use for a specific URL is manual inspection of the PAC file. Unfortunately, this approach is error prone and quickly becomes impractical for large and complex PAC files. Pactester resolves this issue by simulating browser behavior.
