Noel Rappin Writes Here


The New Noel Rappin Dot Com

The New Noel Rappin Dot Com About, oh, eight or nine years ago, I decided I needed a personal website. On the theory that I didn’t want to become a full-time personal website wrangler, I decided to put the site on Squarespace. Squarespace was a great service, and a very well thought out set of tools but over time, it’s become less well suited for my (admittedly minimal) needs: Squarespace costs some money.

The 2019 Books that Made Me Happy List

Books That Made Me Happy 2019 Here’s big old book list for 2019. I did something very weird and nerdy this year. Rather than group the books by type, I just rank them. (I actually kind of rank them every year, but I don’t normally use the ranking in this post because I don’t want it to seem like a competition). To be extra nerdy, what I did this year was write a short program that randomly picked two books and asked me to compare them, and repeated that over and over, then did various math things to convert all those comparisons into a score and then a ranking.

Books that Made me Happy 2018

Books that made me happy 2018 Well, I failed in my plan to get this out by the end of January, but here are the books I liked in 2018. Unlike past years, here they all are in one post, I think it’s about 25. I tried, with mixed success to not write six gazillion words about each book. Enjoy! My favorite book of the year The Calculating Stars / The Fated Sky by Mary Robinette Kowal— if you have ever liked anything I’ve recommended ever, there’s a good chance you’ll like this.


20 some-odd years ago, when I was a graduate student, I spent about two years building Mac applications using a language called Prograph. You’ve likely never heard of it. I want to explain why I’m still kind of obsessed with it. I’ve spent a lot of the intervening 20 years explaining to people why it was great. I’ve I’ve been capable of delivering this as a lightning talk at the drop of a hat at any time in the past ten years.

Developers Toolkit Cheat Sheet

These are a director’s notes on my talk “The Developer’s Toolkit”, you can also watch the video here. It has sources for all the tools mentioned in the talk, and a little commentary that didn’t quite fit in. Hope this is helpful: General References Small, Sharp, Software Tools by Brian Hogan is still in beta but looks to be a good reference to Unix command line things. Which still can be useful, even if I don’t think they are the be-all and end-all.

Pair Programming

Truinboy: Everybody in the Ruby community says they love pair programming. We often use it as a proxy for the awesomeness of a developer shop. Developer candidates regularly ask me if we pair as part of their attempt to determine if we know what we are doing. I wish we’d cut that out. Pairing is not a proxy for how good a development shop is. Pairing is also not, in my experience, a great tool for increasing team productivity and code quality.

Books I Liked in 2017, All In One Part

2017 Books A Plenty At long last, the 2017 books that made me happy/recommendations post. Did you miss me? Past years: 2016 Part 1 Part Two 2015 Part 1 Part Two 2014 SF Fantasy This year, I’m doing it all in one post, because if you are going to write 4000 words it’s best to get it all in at once, that’s just science. The rules are: These are all books I read in 2017 That I liked The books are organized into arbitrary groups, because there were weird coincidences, in that I read a number of say, unusual time-travel books this year.

Wait, I know this one…

Wait, I know this one… Where you have RSpec.configure do |config| config.include Devise::Test::ControllerHelpers, type: :controller config.include Devise::Test::ControllerHelpers, type: :view config.include Devise::Test::IntegrationHelpers, type: :feature end add `config.include Devise::Test::IntegrationHelpers, type: :system`

A Quick Guide to Rails System Tests in RSpec

Just this week, RSpec 3.7 was released with support for the Rails system tests added in Rails 5.1. (If you’d like to read more about system tests and see examples of them in action, my book Rails 5 Test Prescriptions is now avaiable for purchase) What are System tests? System tests were added to Rails core in Rails 5.1 as the core team’s preferred way to test client-side interactions using Capybara and a browser driver.

Union Types in Elm

This is part of a new series of blog posts expanding on or relating to each episode of the Tech Done Right podcast. There are a couple of links through this post going back to specific parts of the podcast. Leave a comment, or follow us on Twitter. This week on the podcast, Corey Haines and I talk about Elm. You should listen to it. Podcasts are perhaps not the world’s best medium for talking about code, so I wanted to dive a little deeper into a couple of things that Corey and I discussed.
