    Ah, even medium sized codebases.
    "Dangerous assumptions"...
    test coverage - we know only a tiny fraction is covered and those tests are incoplete or wrong.
    documentation accuracy - we can't even make that assumption as there is NO documentation what so ever. Yep - management decided "the code is the documentation" (yes, we have that line black on white).
    Use cases - nobody knows.
    ease/cost of migration - we know that is not true - hence why it is constantly sold to customers (and sales-department always acts surprised when we tell them that would be a lot of work).
    semantics - the only assumption we have is "the code does not do what the name implies" as we have "checker"-classes that manipulate data......

    With him until 17 minutes but my large code base is not written using Functional programming techniques in c++,.
    It's all very old procedural c# from 5 years ago and it wasn't even close to cutting edge then.
    The first part of this video is useful but c'mon there is no FP solution to my problem.
    No blame on you.
    Your advice is sound I just think you underestimate the problems out here in Corporate land.
    Luv and Peace.
    Watched all the rest of this.
    I loved C++ at University and used it just once in work in 2003 writing a probing program for Unigraphics.
    Spent my whole life in c# and javascript in web programs.
    More Luv and Peace.

    why do i have a feeling Titus raised his hand at the beginning?

    Am I the only person who thinks that there are no Ninjas and there are no Beautiful APIs. Reality is astonishingly complex. Abstractions leak. There is no large C++ codebase with zero accidental complexity. There is no large codebase in any language that has zero accidental complexity. There are awkward bugfixes. There are workarounds. There are mitigations. There are many many reasons why the code which is useful won't be pure and beautiful.

      While I think what your saying is true (it's true of any engineering system really), I believe one should aim to become as close as possible to a Ninja and try to write APIs that approach beauty. You have to make your best otherwise after some time you will loose control over your product. The ideas mentioned here, to me, are unreachable goals that nonetheless need to be pursued.

      Otherwise what should you aim for? As long as you dont burn out a high goal is a sweet thing.

    • @kuhluhOG

      for big things, there are for sure no completely beautiful APIs, for small things, maybe, but even then it's hard

    Amazing talk 👏 👏👏
    Btw, I prefer Samurai to Ninjas: Samurais were warriors who usually belonged to noble classes of Japanese society. Ninjas were trained as assassins and mercenaries and usually belonged to the lower classes of Japanese society.

    Very depressing talk. In short - don't change anything. You'll make it worse

      that wasn't really the talk, it's more:
      "be careful what you change and be willing to revert a change if it doesn't work out"
