I have been migrating some tests to use github actions from Drone. Locally we use docker-compose to run the app and tests.
There is one annoying difference. The networking setup is different for services. In docker-compose if you have a postgres service it has the network name of postgres. In gha services are all found at localhost.
This makes working across them a choice of either having a host of environment variables that you need to set in each case or having an entire config environment. Having fought with some environment variables for a while I found the distinct configs to be much cleaner. Env variables don’t propagate well through nested processes.
This is the second time that I have attempted to learn Elm. The first time I was reading Seven More Languages That time the chapter dedicated to Elm was highlighting a feature that have been removed from the language by the time I got to the chapter.
I am now working through Elm In Action.
However it does have it’s rough edges. It has strong opinions on use of commas, spacing (if I wanted to fight whitespace I’d be using python).
The language has also not been released much recently and the maintainer does not seem to both with mac support. This means that tools like elm format are broken.
On the positive side the error message do include suggestions on how to fix the current error. They don’t always solve the problem in one step, but can help to find the problem. Oddly the language talks to you in the first person!
I can see that the Elm Architecture could help simplify certain types of development. The plumbing required to add it to a page does resemble Angular 1
The first problem requires a spotters guide to USB
Types of USB Connectors
While USB is the Universal Serial Bus there are lots of combinations out there.
Type A is the usual one used by plugs. Type B used to be used by some printers. Mini is used as the power supply for some devices. Micro A was used for older android phone and kindle devices. Type C is the modern EU approved standard version that is used by all modern phones.
The fun part is that the Garmin has a cable with type A at one end and Mini on the other (this is the end the goes into the Sat Nav). Mac currently only support USB-C. This is fine as I have an adapter.
The first A – Mini cable that I used (because it was in the house) did not work. The Garmin Express helpfully suggested not using a hub and directly connecting to the computer!
The second A – Mini cable that I tried was in my car (and was the official cable). This one works.
Lesson learned: Mac port adapters do work with Garmin!
It is also weak at estimating download times. What started at 2 hours is going to only take 15 mins.
