F# Scripts--Zero to Execute in Ten Seconds

Jomo Fisher--F# is about conciseness. Consider the interview question that asks you to reverse a singly-linked-list. I’ve been asked this question twice in interviews and even the cleanest implementation in the interviewer’s chosen language was long and

Programmatically Resolve Assembly Name to Full Path the Same Way MSBuild Does

Jomo Fisher—Every once in a while I find I need to turn and assembly name like “System” or “System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, processorArchitecture=MSIL” into a path to the actual file for that assembly. This

Correct by Construction in F#

Tight Code--A Puzzle in F#

Jomo Fisher--Luke Hoban wrote something in a blog entry that resonated with me: One of the most striking features of F# code is that it is very terse - ideas can typically be expressed with a small amount of code. Don Syme once mentioned (I'm paraphrasing)
