When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:
main {
max-width: 38rem;
padding: 2rem;
margin: auto;

extend ActiveSupport::Concern | |

#!/bin/sh | |
# Set up Rails app. Run this script immediately after cloning the codebase. | |
# Exit if any subcommand fails | |

# Copy over configs | |
if ! [ -f .env ]; then | |
cp .sample.env .env |
Vue.js is an amazing framework, which can be as powerful as Angular or React, the two big heavy hitters in the world of front-end frameworks.

When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.
There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up. Afterwards, one can look at all the objects, and find out which ones are staying around, causing the
