Observational Report on MVP Submission Video

By Tom Tarpey, Reviewer

Date: July 24, 2025
Project: Migrating an Abandoned Fortran Library to Modern Standards

Overview:
The presenter is modernizing SLATEC, a legacy Fortran 77 math library, to Fortran 90 using AI-assisted tools. The project focuses on migrating 740 math functions, with 10 semi-manually completed, aiming for automated parallelization.

Good Points:

  • Ambitious Challenge: Tackling a 1M+ line Fortran 77 codebase is bold, especially for a solo effort. The choice of SLATEC, though niche, shows a willingness to engage with complex, real-world legacy code.
  • Innovative AI Use: Using LLMs for code migration and validation is creative. The anecdote about AI instances "arguing" over code accuracy highlights an interesting, experimental approach to AI-assisted development.
  • Testing Strategy: Fuzzing the F77 code to generate test cases for validation is a smart way to address the library’s lack of tests, showing problem-solving initiative.
  • Clear Goals: The plan to parallelize the migration of 740 functions demonstrates a focus on scalability and efficiency, aligning with enterprise modernization needs.

Areas for Improvement:

  • Presentation Clarity: The video feels disorganized, with a lot of "uhms" and vague descriptions (e.g., "I don’t know what this one does"). A clearer explanation of a sample function’s purpose would strengthen the demo.
  • Lack of UI: The absence of a UI makes it hard to showcase user-facing value, which could limit the project’s appeal for the target market criterion.
  • Relevance Questioned: The presenter admits the project is "useless" due to modern alternatives, which undermines the market opportunity aspect of the spec. A specific target user segment wasn’t mentioned.
  • Progress Concerns: Only 10 of 740 functions are migrated, and the repo is described as a "disaster." This suggests potential challenges in meeting the 7-day timeline for a production-ready app.

Overall Impression:
The project shows technical promise and creative AI use, but the lack of a clear target user and polished presentation weakens its alignment with the spec. More focus on user value and structured delivery would elevate the submission.
