It's that time of the week again. So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.

Feel free to comment with what you learnt and/or reference your TIL post to give it some more exposure.

Summarize a concept that is new to you.

And remember, if something you learnt was a big win for you, then you know where to drop it as well.👇👇🏻👇🏼👇🏽👇🏾👇🏿

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

e.g. the following is perfectly valid

PATH=$PATH:/my/new/path/
Enter fullscreen mode Exit fullscreen mode

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/"
Enter fullscreen mode Exit fullscreen mode

Whether quotes are needed in different languages is so inconsistent 😄

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!
