Are there businesses building automation and tooling for working with legacy codebases? It seems like a really good "niche" for a startup. The target market grows faster every year :)

Specifically to do what?
- artursapek 9y ago
  - Help developers build a high level understanding of the code and relationships between modules (with millions of lines, this is extremely hard) - Automate refactoring code to reduce complexity and cross-dependencies - Automate rewriting parts of code in mode modern languages and replacing it with some mediation layer (protobuf etc) I think industries like finance would welcome with open arms something that can do this. And it could go for a high price if it's still saving them money on countless hours of developer time. It's a growing cost every year to maintain legacy code that was written 3+ developer generations ago, and it's dangerous in cases where peoples' lives depend on the code being bug-free (infrastructure, medical) I started thinking about this problem a few days ago in a thread about AI https://news.ycombinator.com/item?id=14430652 https://news.ycombinator.com/item?id=14430652

    I think some of this already exists using APM and code analysis. The only issue is existing toolsets often display ugly diagrams in like ER format or some flow diagram. Hard to read.

  Interesting, thanks! Sounds like it's a really hard problem.

Tools like NDEpend (for .NET) help me a bit with modularizing. I doubt we'll ever see automation beyond what we do today in this space.

    Yeah I'm very very pessimistic in that area. Effectively I think cleaning up bad/tangled OO code to be such a difficult problem that the level of AI required is beyond not just what we can achieve but beyond what we can imagine. For example I believe it's much harder than coding entirely new applications from text descriptions of its features. That would limit the usefulness of an AI that can untangle existing code...
