Identify two possible team projects for this semester, both portable apps, but of the following two sorts.

• An application that you think is both interesting and tractable
• A wacky application that would really be sweet, but is probably impossible to build

One short paragraph should be sufficient for each idea. Record your proposals in a simple ASCII text file (ideas.txt) so that you can submit it later.

Please answer following questions:

1. Demographics

   1. What is your class level? (freshman, sophomore, junior, senior, [super-]+senior)

   2. What is your major? (BCS, CS+, …)

   3. What letter grades did you get in CS 112 and 212?

   4. What CS 262 section are you in (A or B)? Can you attend the full Friday lab session, and, therefore, be on a team with members of the other class section?

2. Technical

   1. Have you worked on any of the following things:

      • JavaScript/Typescript applications
      • SQL database systems

      If so, what (briefly) have you done?

   2. Have you used any of the following tools:

      • Slack
      • Trello
      • Git and/or GitHub

      If so, what have you used an how (briefly) have you used it?

   3. What project or projects would you like to work on. Include at least one tractable project, say from the previous lab exercise or from the suggested projects in the team project specification.

   If you’d like, talk to other students or use the Moodle forum to form groups interested in particular project ideas.

3. Personality

   1. What is your big-five personality type? Please include these scores in your lab solution and, if you haven’t already done so, enter them using this form as well: CS 262 - Personality Traits. (See the reading guide for how to determine this. Please, give the five trait values only.)

   2. Is there anyone you’d really like (or not like!) to work with? We’ll do our best to honor your requests here.

4. Is there anything else you’d like us to know about you before assigning you to a project team?

Save your answers in an ASCII file (teams.txt) so that you can submit them as part of this lab assignment. If you work on a team of two students, please put both of your names in this file.

Do Expo’s Get started tutorial. Create a lab01/ directory and do the following sections as written in that directory. Notes:

1. “Create a project” — Do this as written, using the default template.
2. “Set up your environment” — We suggest that you install Expo Go on your mobile device, using the Web emulator as a backup.
3. “Start developing”
   • Because Expo expects your computer and your mobile device to be on the same network, which may not always be true (e.g., on the machines in our labs or when using Windows/WSL2), you may need to use Tunneling.
   • When you’re making changes to the code, try creating some errors so that you can practice using Expo’s tools for Debugging runtime issues.
4. “Next steps”
   1. Remove the boilerplate code as explained here, and also delete the app-example/ sub-directory. This gives you a basic app structure with no boilerplate code that you use as a basis for future applications.
   2. Modify the hello message to say “Hello, Expo!” and shown on the right.

When you have the app running on your device, save a screen shot of your running application and add a new README.md that contains a list of one-sentence explanations of the purpose of each of the following files/directories in your project code:

• app/(tabs)/index.tsx
• package.json
• node_modules/
• .gitignore

Store your screenshot and readme files as sibling files in the root of your application directory and be prepared to submit these files: your (modified) lab01/my-app/app/index.tsx; lab01/screenshot.png; and lab01/README.md.
