Pizzlet Information System “When Spam just isn’t good enough…” Troy Lamberte Blake Norrish

Operational Concepts (Overview) The Pizzlet Information System (PIS) facilitates the gathering and distribution of “Free Stuff” information. A server application receives and parses s from an address, and sends relevant “free stuff” information to a list users running the Pizzlet Midlet on their cell phones. This is aimed at University of Washington students and the free food that is regularly distributed around campus.

System Requirements What DOES it do for us? User Scenario 1 (setup) 1) Bob hears about Pizzlet from a CS friend 2) Bob logs onto the World Wide Web 3) Bob navigates to the URL homepage of the Pizzlet Server. 4) Bob enters his username, cell phone number, and preferences about what kind of information he would like to receive. 5) Bob downloads the Midlet portion of Pizzlet to his cell phone. Bob leaves User Scenario 2 (use) 1) Bob is sitting on campus like he always does 2) Bob is hungry like he always is 3) Bob uses his cell phone to check the latest information from Pizzlet. 4) Bob sees that there is some sort of Engineering kickoff meeting tonight in the HUB, and they have free pizza 5) Bob goes, and eats free pizza

System Requirements (2) What it looks like: (Web part)

System and Software Architecture The Components 1. Component; Responsible for connection and retrieval 2.Parsing Object; Responsible for looking at and determining if its “free stuff” 3.Database Connection Object; Needed to get list of user’s cell phone numbers for info distribution 4.Client Communication Object; Responsible for ending data to client’s cell phone 5.Pizzlet Midlet; On Cell phone, responsible for displaying info received from Pizzlet Server

Components (visual)

The Hard Parts: retrieval and Parsing Use JavaMail API and JavaBeans Activation Framework to get mail. Use forwarding to internet POP server to bypass need for SSL or TLS (JavaMail does not support) It works… we already did it. Parsing: Search on predefined keywords/phrases in subject/body Assign “confidence” depending on number/type of keywords found High “Confidence” means free stuff, send info to cell phones Also use “filter” word to weed out junk, porn, etc.

Lifecycle Plan Who wants it? I do, you do, we do, Bob does. And who will support it? Little support needed. configuration needed (about) quarterly to keep Pizzlet’s address on lots of distribution lists. Tech Support: BYOTS (and RTFM?)

Conclusions: No known technical impossibilities – retreival solved –Parsing reasonable Good Product /Work ratio –Isn’t a huge project (small work), but could be an interesting solution (Nice Product) Known user base –Me –You –Bob But….

… Some things that could go wrong Our system is dependent on a web-based free server. –Policy change (no free POP acocunts) –Out of business JackA**’s –People who know about system could easily compromise it, send false s, etc

FINAL Conclusion Build it.
