Your private information manager• Communication:
– mail– faxes– phone calls
• What to do– calendar– tasks– projects
• Archive– documents (with multiple versions)– history– where you have been, where you served
Your private assistant
• Assist to execute complex tasks– maintain the time on your video recorder– remember to put the garbage out– prioritize and group incoming messages– handle the supplementary services on your mobile
• Act as a representative– answer the phone, forward messages– allow access to certain information (via web, phone,mail)
• Maintain focus (nagging mode)– action points– promises made to other people– goals
Key aspects
• Reliability, Robustness and Availability– backup– good software
• Security– encryption of all information– secure access, e.g. SSL– key management– access by third parties
• Open for third party applets– run inside Marvin for access to events– cooperate with central services

transaction implementation
• Bracketing of tasks– begin transaction– do something
» failure: rollback EVERYTHING» success: commit EVERYTHING
• Two phase commit model for distributed systems
• Allows multiple implementations– Iparticipant, Transaction, Coordinator
• Logging facilities for undo/redo
• Comes with a “SimpleTransactionManager”
transaction, open points
• Interface to Voyagers transactions
• Implementation of undo/redo logs
• Get the department committed to it ;-)

• Associations are (will be) time stamped
• Triggers services on changes
• Intended replacement for file system
InfoBase, communications• All communications pass through the InfoBase

• Life cycle management: install, initialize, start, stop, shutdown, uninstall.
services, features II
• Marvin naming interface (through System properties)
• Shell interface (through Telnet)– lifecyle– inspection– service properties access (a la Beans)– interface to file system

• Partial implementation of IMAP based on javax.mail
• Supports notifications (unfortunately Netscape seems to be deaf … )
• Supported commands:– noop logout select examine– create list status close– fetch copy uid
• InfoBase & IMAP: a marriage made in Kista– notifications & listeners– mime types– attachments through web interface

mail, open points
• Robustness, javax.mail has some bugs that are hard to circumvent
• Support for IMAP mail boxes (easy because of javax.mail)
• Better logging (and error reporting)
• Should be based on central scheduler instead of thread based delay

javax.mail
• Supports MIME messages and an IMAP like folder structure
• Comes with standard interfaces:– to IMAP server– to SMTP server
• Abstract, but very close to IMAP semantics
• Many convenient utilities for handling of MIME
javax.activation
• Standard library to connect MIME typed objects to handlers
• DataSource interface is VERY useful
• Belongs to beans
javax.servlet
• Standard interface for request/reply interactions like HTTP
• Will adapt the web server to use servlets
com.odi (PSE + PSE Pro)
• Free object oriented database
• Reliable and fast
• Smart access algorithm for persistent data
• Single user
• Transactions
• Pro version supports recovery and access tools but costs a couple of hundred dollars
• Same interface as ObjectStore
com.objectspace (Voyager)
• Distributed objects framework
• Makes distributed objects largely transparent
• Considerably simplified from an already simple system
• Version 1 or version 2?
• License issues are unclear?

Surfboard
• Not much done on Surfboard yet
• Possible solution is to buy a flat screen and connect it over a video link over IR from Sony
• Would require hardware handling
• Who picks it up??

Earth to BBox
• We need something a bit more realistic than the BBox
• The SIM application toolkit (GSM 11.11) offers good possibilities on modern mobiles (GSM Phase 2+)
• In contact with Schlumberger and G&D for development support
• Obtaining an authorized card looks not easy
• Seems like the right stuff for our department

SIM application toolkit interface
• Marvin can ask the mobile to:– setup a call from the mobile to a number– forward the phone to another number– add document summaries to the menu– display a message– changes to the phonebook– request input from the user– set any supplementary services
SIM application toolkit interface II
• The mobile must report– Location change (Cell Identification + LAC + NMC)– Cell broadcast info– Selection of a document summary– Incoming numbers + duration (might be hard)– Incoming SMS– Send input– Battery
Other projects
• eBox– Linux based– Many overlapping concepts– Carlstedt, CSLab, Hans Thorsen, Malte Lillestralen– First goal is to use it for metering water, later through ISPs in the
home– Seems very Java oriented– Good spirit, high ambition– Have access to a factory (Linkoping)
• Win 95 home server (made in Karlstad)– WinFax like product– Win 95 does not seem to be right OS to me– Have no update of their status lately
Next phase
• Introducing class for the following concepts:
– Marvin personality– The channels to the end user and their capabilities– Task management
• Easy Speech support for the services (Speech agent)
• Mobile interface
• Cooperation with others
• Robustness, Reliability
Next next phase
• Connections in the house
• Switching of video
• Security
• Surfboard
• ???
