When you edit your $PATH environment variable, you don't have to use quotes

e.g. the following is perfectly valid

I always thought you had to do the following, just in case $PATH expanded into something with a space, but it turns out it's fine either way

PATH="$PATH:/my/new/path/"

I've been playing around with React and leaflet in my free time. I've learned quite a bit building this, which I've been working on for the last several weeks. The latest issue I resolved was handling multiple markers in the exact same location on the leaflet map using a cool library called react-leaflet-marketcluster.

For me I discovered why I was having trouble seeding my database for development. Forem, the software that runs dev.to, uses Ruby on Rails and I discovered, along with a coworker that disabling Spring fixed the errors that were preventing the database from seeding. Shout out to my coworker Dan for the help!
