@nikolovlazar.com shows us how to debug these errors anyway—piecing together the missing context across systems so you can actually fix the problem instead of just guessing. Curious? Check out the video to see how we make it a bit less painful youtu.be/wb4Km8pCZRY

Just finished @aaronfrancis.com’s screencasting.com and it inspired me to change up my setup for the millionth time. Also, I wish this course existed years ago. I’ve had to learn most of the things Aaron teach by trial an error, but also learned a few new things. screencasting.com is worth it!

I figured it out! One day (Wednesdays) we’ll do other activities like code reviews, read books and articles, explore libraries, design patterns… I’ll be introducing the new program tomorrow at 9 AM EST. It’s going to be exciting!

I just posted this in my Discord creatures.sh. I'm thinking of diversifying my live streams - one day a week where we continue building projects, and another day where we check out links, explore libraries, read books! LMK what you think of this idea, and which book we should start with.

Do you think we’ll produce more value if each episode was something different? We could learn something new every episode, and the topics can be sourced by the community. You’ll post links in my Discord server (we’ll create a forum) and we’ll pick a posting to explore.

OK. So, here we go! #bskycourse is officially live! Originally published on Twitter I am once again glad to welcome you all, future developers, curious lurkers, and fellow engineers. This first course is going to be about a very cool language called Go (or golang for short).

The deeper I dive into Django the more I like it. I implemented DRF's simplejwt plugin today and got the JWT token endpoints automatically created just by adding simplejwt as an app. I just needed to create the register view and I've already got a basic form of auth in no time.
