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.πŸ‘‡πŸ‘‡πŸ»πŸ‘‡πŸΌπŸ‘‡πŸ½πŸ‘‡πŸΎπŸ‘‡πŸΏ

Thanks for hosting these weekly learning threads Nick!!!

I learned

  • πŸ₯³ Linux has a built in VIM tutorial: vimtutor
  • 😬 First hand of a potent async related error referred to as a race condition
  • πŸ˜ƒ We're able to leave a trail of breadcrumbs in the terminal with:
    • pushd - use for remembering more than one directory. use in place of cd
    • popd - reverse back through the saved directories
    • dirs - list of directories

I learned about file permissions in Linux, what the numbers mean when using the chmod command, and that using the numbers is shorthand for assigning file permissions to users, groups, and others. I highly recommend this post to anyone interested.

I learned about imagemagick and how to compose an image with a mask and a gradient. I use this to create colored icons for my look and feel in awesome wm. I got inspired by icon packs like neon for kde but I wanted to have my own colors and a consistent pallet and I just need a few for my statusbar.

Hey Nick!

I learned Gridsome/JAMstack this week and I set everything up with a Headless CMS, which is a first for me. Cool stuff!

Did you learn anything new?

I've learned a bit about code coverage tooling, mainly through publishing my blog series on, API's from dev to production; specifically part 3 that was posted today right here on

I've looked into and it's worked great, took minutes to setup and have it working, and I highly recommend it.

I've also looked into, unfortunately it isn't working that well right now, setup was easy, just like Codecov, and I'm working with the Coveralls community through a GitHub issue to resolve.

I feel these kinds of platforms for code coverage do offer value.

I integrated Firebase and Vercel emulators in my application setup to do local development and there were many things to learn. Feeling satisfied about this week's hard work! πŸ™‚
