My LambdaConf experience

I just finished an incredible (and exhausting) week at LambdaConf in Boulder, Colorado. I can say with confidence that it's the best programming conference I've attended, and I'm anxious to be able to attend it again in the future.

Stepping outside my comfort zone

I wouldn't call myself terribly experienced - 28 years old and only 4 years out of college - but I have developed a professional comfort in a few areas:

• Interacting with F# developers
• Interacting with C# developers

Priority-ordered list for an F# Europe conference

Aiming for 200+ attendees

Cost should be reasonable, but not free (200+ Euros equivalent)

• Quality coffee and tea
• Travel for speakers and family
• Lodging for speakers and family
• Speakers get a free ticket to give to someone (no travel/lodging for this person)

// First, define a 'zip' function
module Result =
    let zip x1 x2 = 
        match x1,x2 with
        | Ok x1res, Ok x2res -> Ok (x1res, x2res)
        | Error e, _ -> Error e
        | _, Error e -> Error e

type ResultBuilder() =
    member _.MergeSources(t1: Result<'T,'U>, t2: Result<'T1,'U>) = Result.zip t1 t2
