Meeting Summary for CS 326 Lecture/Lab – Spring 2025

Date & Time: January 29, 2025, 06:32 PM Pacific Time (US and Canada)
Meeting ID: 813 3845 7711

This document provides a structured summary of the meeting, including key points discussed by Greg, tasks assigned to participants, and technical guidance on lab progress, development tools, and repositories.

Quick Recap

During the session, Greg reviewed the expectations for the upcoming lab session. The meeting covered the following:

  • Preparation:
    Participants must ensure that their development environments are set up with the necessary tools prior to the demonstration.

  • Lab Assignments:
    Emphasis was placed on progressing with lab assignments, particularly Lab 1 and Lab 2. The Autograder setup was highlighted as a priority.

  • New Tools:
    A new tool called Roo Code was introduced, which is touted as more efficient than Aider. Participants are encouraged to try it as an alternative or complement to Aider.

  • Technical Guidance:
    The meeting included discussions on using the terminal for Qemu, working with choices, and accessing specific repositories including the ‘root code’ extensions.

Next Steps for Participants

Participants are required to complete several tasks to prepare for the next session. The tasks are as follows:

  • Development Setup Demonstration:
    • Perform an LLM CLI call with a simple prompt.
    • Set up Aider and you can run it locally.
    • Compile and build xv6.
    • Run the Hello and Sum programs on RISC-V.
  • Lab 1 Update:
    • Redo Lab 1 using the new GitHub repository provided.
    • Use the Autograder for submission and testing.
  • Autograder Installation:
    • Install and set up the Autograder by following the instructions in the README.
  • Roo Code Installation:
    • Consider installing and using Roo Code, either as an alternative to or a complement for Aider.
    • Set up Visual Studio Code along with the Roo Code extension.
    • Obtain and configure an OpenRouter API key for Roo Code integration.

Detailed Summary

Preparing for the Upcoming Session

Greg emphasized the key preparation tasks:

  • Ensure that all development tools such as the LLM CLI and Aider are correctly installed.
  • Get ready to demonstrate functionality by compiling and running programs (xv6, hello, sumargs).
  • Preconfigure prompt executions to maintain efficiency during the session.
  • Work with APIs like OpenRouter and Google Gemini, ensuring that necessary integrations are in place.

Progress on Lab 1 and Lab 2

Greg highlighted the following points regarding the labs:

  • Autograder Implementation:
    • The lab progress relies on getting the Autograder working correctly.
    • Participants should test the Autograder using the provided GitHub repository for Lab 1.
    • Tests for Lab 1 will be provided to ensure the Autograder is functioning as expected.
  • Tool Introduction:
    • Roo Code was introduced as an efficient alternative to Aider, with a demonstration on how to set it up and use it in projects.

Qemu Choices and Root Code Access

Additional technical details included:

  • Qemu Terminal Usage:
    • Discussion on how to effectively use choices and navigate the terminal when running Qemu.
  • Alternate Workflow with Roo Code:
    • Consideration was given to using Roo Code instead of other tools (e.g., Aider).
  • Repository Access:
    • Guidance was provided on accessing the ‘root code’ repository, specifically focusing on extensions and dynamic usage.
  • Transition Instructions:
    • Greg mentioned shutting down his computer to move it to another location, with further instructions from Kvon scheduled when necessary.

Concrete Example: xv6-riscv “Hello” Program

To help make the concepts more concrete, below is a simplified C code snippet from xv6-riscv that demonstrates a basic “Hello, world” program. This example can serve as a starting point for compiling and running on the RISC-V architecture.

#include "types.h"
#include "user.h"

int
main(int argc, char *argv[])
{
    printf(1, "Hello, world!\n");
    exit();
}

Explanation

  • The code includes essential heAiders for types and user functions.
  • The main function calls printf to display “Hello, world!” to the console.
  • The program terminates using the exit() system call.
