Recently, I was tasked with creating a new screen containing a table of data for a project using React and Apollo. In the past, we would typically start by defining the database table, other access layers in between that and a GraphQL query schema, and finally the query on the front end using Apollo. This has been quite tedious, and often, we ended up tweaking the schema many times until we ended up with precisely what the front-end UI needed.

Excel Snapshot Testing with Node
A couple of weeks after I worked on PDF snapshot testing with Node and GraphicsMagick, I was tasked with writing some code to generate downloadable Microsoft Excel Workbook files. I thought I would use snapshot comparisons again, much as I did with PDF files to automatically detect regressions in the implementation. Read more on Excel Snapshot Testing with Node…
PDF Snapshot Testing with Node and GraphicsMagick
The task I am working on this week involves generating downloadable PDF files for customer and supplier orders. We’d like to drive the implementation using tests and be able to find any regressions in the code automatically.
After looking at different alternatives for accomplishing this, we decided to try a visual snapshot approach similar to the way Jest does snapshot testing.

Remote File Editing Over SSH with Visual Studio Code
Recently, I needed to add an entry to the local domain name server on my home network. For many years, I have used Emacs to edit files on the terminal both locally and on remote systems. However, over the past year or so, I’ve become familiar with Visual Studio Code, and I very much enjoy its editing experience. I searched through the available extensions and found one called Remote VSCode.

Simple Database Dump/Restore with Postgres on Heroku
On my current project, we use Postgres instances running on Heroku for both staging and production. Each team member on the project also maintains a local instance of Postgres used for development.
Because the process to translate data from our customer’s legacy database to our new system takes quite some time, we run the process nightly to populate our Postgres instance on our staging server. In addition to our automated test suite which generates and uses its own test data, we found it quite useful to be able to use up-to-date, real-world data during our daily development and ad-hoc testing of our software.

Building a Siri/iOS HomeKit-Enabled Garage Door Control with Raspberry Pi – Part 1: Hardware
This summer, I decided to explore home automation using a Raspberry Pi. I thought that it would be fun to control my garage door with Siri/iOS HomeKit and spent some time building a basic controller using JavaScript and some nice Node.js packages.

One Month at Atomic Object: Musings of a Corporate Defector
My on-boarding process at Atomic Object was almost a year in the making. While I was on assignment for GE Aviation to their joint venture company in Shanghai, China, I learned that my contract was not to be renewed for another year. It was part of a cost cutting measure to trim out a large number of corporate expats. This was not totally unexpected as our costs were extremely high.
