My Development Setup
Sat, Mar 2, 2019 - ~300 Words
Terminal / Shell Dotfiles use the Thoughtbot collection as a lightweight base, with all customisation performed in a separate dotfiles-local repository. This gets me: Basic configuration of zsh A basic tmux setup vim/nvim integrated with tmux such that moving between vim and tmux panes is seamless, using the same motions. And most importantly, with this approach there are no lines in the config that I do not understand. Using Alacritty for a lower-latency experience.

Readline Problems With Ruby on OSX
Fri, Mar 1, 2019 - ~300 Words
Update: This issue may have been caused by an update to OSX Mojave which moved the location of header/library files. This post describes a fix which could help avoid the need to rebuild the Ruby version (and all gems). A recurring issue with running a Ruby development environment on OSX is integrations with external libraries, particularly readline. As various elements of the setup evolve (e.g. OSX, Homebrew, Ruby, rbenv) breakage occurs which causes development time to be spent debugging basic machine issues.

Simpler Handling of AJAX Form Errors in Rails 4
Thu, Aug 18, 2016 - ~1500 Words
The Problem With unobtrusive Javascript, converting a form in Rails to use AJAX is as easy as setting remote: true: = form_for Client.new, remote: true do |form| = form.text_field :name This will cause our form to submit asynchronously, and expect a Javascript response, which will be executed directly to e.g. update the page appropriately. DHH recommends that we design our apps in this manner, where in the Javascript response we re-render the model using its template and use jQuery to update the HTML on the page.

Kinesis Freestyle 2 Keyboard Review
Sun, Mar 6, 2016 - ~200 Words
First Impressions First impression upon unboxing the keyboard is that all of the reviews that I had read were out of date–Kinesis have clearly paid attention to feedback and some of the gripes that I had read about (e.g. having a browser ‘home’ hotkey, making the insert function require the pressing of fn) had been addressed. As such, the keyboard layout is easily standard enough to allow for a smooth transition from a regular keyboard (Apple wired and wireless keyboards) to the Kinesis–thus far I have not experienced any real slowdown in typing speed.

Robust Integration Testing in Rails 4 with RSpec, Capybara and Selenium
Wed, Aug 20, 2014 - ~2900 Words
The Problem Using RSpec and Capybara to test your Rails apps can make writing tests easier which is good both from a perspective of getting people to actually write tests but also for our general productivity as developers. While it has its detractors, I like the terse syntax and ease with which we can define our own helpers which help set up certain contexts such as in this case setting up the default account and switching into its subdomain:
