Working solution for laradock

spin up the selenium image (selenium/standalone-chrome) as included with laradock
in .env.dusk.local set APP_URL=http://nginx to point to the docker nginx image
in tests\DuskTestCase.php replace the line 'http://localhost:9515', DesiredCapabilities::chrome() with 'http://selenium:4444/wd/hub', DesiredCapabilities::chrome()
run php artisan dusk

Find the dependent child images on Docker

When you try to remove the docker image with the following command

docker rmi 6795374be8c1

Sometimes you might be facing below error:

Error response from daemon: conflict: unable to delete 6795374be8c1 (cannot be forced) - image has dependent child images

Below is the Docker command line used to find the dependent child images

Array Iteration

https://gist.github.com/ljharb/58faf1cfcb4e6808f74aae4ef7944cff

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it mu

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Disabling GNOME Tracker and Other Info

GNOME's tracker is a CPU and privacy hog. There's a pretty good case as to why it's neither useful nor necessary here: http://lduros.net/posts/tracker-sucks-thanks-tracker/

After discovering it chowing 2 cores, I decided to go about disabling it.
