Experience

Taking Firebase Serverless

https://www.toptal.com/google/firebase-serverless-mobile-and-web-apps

Firebase is a suite of over 20 components that greatly simplify the creation of mobile and web applications. It is fully integrated with the Google Cloud Platform (GCP). I developed a workshop highlighting the use of Firebase for front-end developers. As part of the process, I was in direct contact with the Firebase team at Google. The focus is to allow developers to develop end-to-end applications without needing a back-end server. All back-end components are deployed directly into the Google Cloud using Cloud Functions and Cloud Run.

Pandoc and Docker Publication Chain

https://www.toptal.com/docker/pandoc-docker-publication-chain

Moving into a new computer is a time-consuming and often frustrating process. The software needs to be installed, and data needs to be moved. Having purchased a new Mac Mini, I didn't want to go through this process, so I made some decisions.

First, data files: I purchased a NAS, which has RAID backup, and most of the files are also in the cloud in Github. NFS mounting the NBAS drives allows multiple machines to access them, and there is no need to copy files other than to the NAS.

Installing and updating software is always tricky. This is particularly true if there are dependencies. A solution to this is to run the software in Docker images. I decided to use this approach. The complex Docker run command can be wrapped in an alias, a function, or a script.

Another issue is documentation. Documents are often required in multiple formats, including HTML, PDF, and proprietary. The other issue is that documents are ideally in a text format for versioning. There is an ideal solution. Markdown is a commonly used document format. The Pandoc software can easily convert markdown to other formats, eliminating the need for multiple copies of the same document.

Astronomical Predictions and Simulations

https://dr-phill-edwards.eu/

I wanted to predict the times of astronomical events, so I have an ongoing Java project to build a suite of programs to predict events and model the solar system. There are sections on my website which show some of the calculations and results.

Most of the current literature is based on unexplained approximations. Still, I found the NASA JPL Ephemerides Data, which allows the accurate calculation of the positions of the sun, moon, and planets between the years 1550 and 2550.

The application is currently being rewritten in Go.
