Other Aspects of F#

Learning F# as part of a real project is more than just the application code, it’s everything that’s involved with building up the system requirements to deploying updates. At this point in my adventure my attempts at working FRP into the solution weren’t proving fruitful, so I found it easier to focus on the rest of the ecosystem and other aspects of the solution. Testing There was an upside to creating a system that didn’t work; to discover why it didn’t work I needed a much more powerful testing framework than before.

Domain Context

A coworker was talking to me about how difficult it can be sometimes to explain technical problems to non-technical users. Most users want to know how the system works, especially if it’s critical to their daily responsibilities, but it’s important for software developers to draw a line where the domain ends and the technical details remain. Saying a problem was caused by a key consistency error from something strange with Posgres sequences should not mean anything to a user wondering why restoring old data didn’t work.

Trying F#

I’ve previously mentioned a passing interest in F# because it was sufficiently different from languages I knew and had many concepts that sounded immediately useful. It took me almost 2 years to take the plunge and implement a non-trivial app in F#. It took 3 tries to get something that felt usable and idiomatic. This the first part of my journal of lessons learned. Starting out I didn’t buy any books or take any classes, but I did read every bit of literature online before writing anything at all.

Vision is the hardest

I started off my career thinking that coding was the hardest thing I had to do every day. That fixing bugs, building features, and writing documentation was the toughest part of building software. It’s what I spent all my time studying in school, so I figured that once I knew how to code well enough to make things work, the rest of the job would be easy. I heard “The first programing language is the hardest”, so I expected to struggle with the basics.


A Reintroduction I’m moving my content from tumblr to here. I only used tumblr before because it was resonably public and seperate from other blogging and social networks that I already had established. Now I have a dedicated site serves that same purpose (with a higher cost to me of course). Tumblr had fine formatting tools and tagging, but since I didn’t visit it often or interact with anyone on the site I figured I might as well just make my own island for this stuff.
