1. Quizlet. Please fill this out even if you haven’t done the reading.

2. Discussion of technical debt.

3. Query diagrams intro..

4. Make query diagrams for three queries on the ‘run-imageapp.py’ server in my repo, under branch day18; specifically, ‘/image’, ‘/upload’, and ‘/upload2’. Include the process of actually uploading a file via /upload2. (note the ‘imageapp’ directory contains two png files that you can upload).

   Note: you can do a clean checkout into the directory ‘day18’ by doing:

   git clone https://github.com/ctb/cse491-serverz.git day18 -b day18
   

   and run it with ‘run-imageapp.py’.

   Also note: these are example solutions for the JavaScript stuff in Day 16: Thursday, Feb 27th, 2014.

   In class, draw three diagrams on a piece of paper or with a graphics program, put your NetID on the top of one page, and hand them in via e-mail or (gasp) by hand. Feel free to work in groups of 2-3; just include all y’all’s NetID.

   Last note - you can track requests by looking at your running imageapp server output. (Ignore the favicon.ico request.)

5. Brief going over of Homework 8.
