May 8th, 2020: What did you learn this week?

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.

![A picture it a dog waving their paw with the caption “Learning, cool at school or at home”](

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.👇👇🏻👇🏼👇🏽👇🏾👇🏿

I'm also taking that course, it is great. Dr. Laurie Santos also has a podcast The Happiness Lab which is also a good listen.

I've learned how to use Bash scripts to monitor some of servers status :).

The related tutorial is available here.

I also use systemd-ngrok to let some machines can use proxy server to let me connect from Internet :).

It can help me to monitor server stats easily & conveniently.

In Go, when you want to unmarshall a json into an unexported struct, its fields should be exported. This is because json is a different package and doesn't have the power to view fields unless they are exported.

I learned a bit about styled-components. I was never a huge fan of the approach, but I think it is growing on me, it definitely helps clean up and make maintaining React code easier.

That puppy gif is the cutest!

This week, I learned that each instance of a React class component has it's own State. It didn't click until the reviewer pointed it out during my project review.

Learned that Rails syntax in html is as ugly as any other mvc framework.
After Rails syntax JSPs looks just fine and Razor is actually normal.
Routes in Rails are such a mess.
