# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

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

We are building a Node.js service which will need asynchronous support for tasks like sending emails. Here's our evaluation:

• kue
  • https://github.com/Automattic/kue
  • Good: Seems well documented
  • Good: Supports retries and backoff
  • Good: Uses Redis so 1 less thing to maintain
  • Bad: Only supports Redis so have to wary of key eviction at later stages of growth
  • Bad: Slow to resolve issues

/*
This .scss loop will create "margin helpers" and "padding helpers" for use in your web projects.
It will generate several classes such as:

.m-r-10 which gives margin-right 10 pixels.
.m-r-15 gives MARGIN to the RIGHT 15 pixels.
.m-t-15 gives MARGIN to the TOP 15 pixels and so on.

.p-b-5 gives PADDING to the BOTTOM of 5 pixels
.p-l-40 gives PADDING to the LEFT of 40 pixels
