A bit of Railway Oriented Programming with Coconut

Using Coconut/Python to build a pipeline with error handling

Why am I doing this?

I recently did a talk on Coconut at the Tucson Python Meetup (aka TuPLE). I mostly demoed the examples in the tutorial and the documentation, but I also came up with a way to do error handling like I do in F# with Railway Oriented Programming that I learned from F# for Fun and Profit.

You can find my source code on . . .

Pure F# Web API and Team City Build

How I fixed the broken build

We use TeamCity at work for continuous integration. I recently added a Pure F# Web API to a solution. Everything was building but this one project. The build (with FAKE) ran just fine locally, but in the Team City environment, running the same FAKE script, the build broke.

And all I got was this fun error:

D:\TeamCity\buildAgent\work\ . . .

Suave bootstrapper upgraded

Why am I doing this?

I recently started building a web API at work. I am building it in F# as a .Net Web API project. This is nice and all but not wholly a functional programming kind of thing. So I thought I would try Suave.io, which is F# all the way through and encourages a functional style, and all the cool kids are doing it.

Hello world! with Vue.js & Webpack

Getting started with Vue & Webpack in an .NET MVC app

Why am I doing this?

We are starting to use Vue.js at work and I wanted to get familiar with it and possibly use it in my personal projects. At the time we are not using Webpack with Vue.js, but we are planning on using it at some stage so I also wanted to learn about Webpack.

What is Vue.js?

Vue.js is yet another Javascript web framework, . . .

Neo4j Type Provider

My tiny contribution

Why am I doing this?

One of the most awesomest things about F# is Type Providers. There are Type Providers for, like, everything. A while ago I found a Neo4j Type Provider built by Pete Bayne, who was kind enough to help me a bit when I was having trouble getting the code to compile. I did end up making some small changes to get it to work. . . .

An IVR with Neo4j and F# -- Part 2 A

Modeling the IVR domain with algebraic data types

Why am I doing this?

In part 1 I talked about getting started on my graph-based IVR system. I started with modeling the authentication sub-graph. I wrote some Cypher queries to build the graph in Neo4j. In this part I am going to talk about how I modeled the graph in F# using algebraic data types, namely discriminated unions and tuples.

This . . .
