Hack your commit history for fun and profit with F#
View abstract.txt
We programmers spend so much of our time coding everyday, and there's a wealth of information about
HOW we work hidden in our commit histories.
In this talk I'll share some of the ideas we experimented with to analyze our commit history in order
to gain insight into the way we work, and how the quality of our codebase has evolved over time.
Along the way, there were some rather interesting findings!
All the code examples will be in F#, but you can easily apply the same techniques in any other language.

static class AsyncResultExtensions
//added to chain awaitable methods
public static async Task<Result<TResult>> OnSuccessAsync<T, TResult>(this Result<T> result, Func<T, Task<Result<TResult>>> func)
var res = result;
if (res.Failed)
return Result<TResult>.Fail(res.Error);
return await func(res.Value);
