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

This is probably embarrassing but I'm sharing anyway: I learned a GitHub fork is basically just a branch. I've always re-forked other people's repos to work on them again. Turns out, you can just rebase in your existing fork like on your own local repos:

$ git remote add upstream https://github.com/someone_elses/repository.git
$ git fetch upstream
$ git checkout master
$ git rebase upstream/master 

Done! None of these steps are new concepts for me, at all, I just never put two and two together in this context somehow. I would imagine pretty much everyone does it this way instead of the caveman-like nonsense I was up to before. Thanks, StackOverflow. Never leave me.

 

I learned (am still learning) that building and managing a startup is much more different and difficult than just building a side project only you'll be using. You have to market yourself, get new users registered, keep them happy, and constantly ask for feedback. I'm still adjusting to all of this.

It's at debugg.me

 

I got the chance to attend Australia's first ReactConf, and I think I learned a lot!

One of the coolest for me was model-based testing, which I had never heard of before, but I am keen to give it a go at some point in the future.

 

I learned that Windows 10 has a "dark mode" and now my life is ever so slightly better (and darker).

 

For this week I focused learn how to hardening Linux operating system and docker/container internal system, I confused when first started, but when I learn more deep, I can understand why we need hardened system on our production server and how docker and other container system work(in internal, not just shell) ...

 

Getting my side project to Angular 9 and took the time to write an article about why you should do that too πŸ’ͺπŸ’ͺ

 

Awesome! What are the benefits of using Angular 9?

 

To make it short, smaller bundle, better runtime performance and template type checking. Here's the full article in case you want to take a look dev.to/thisdotmedia/this-is-why-yo...

That's Awsome article! Thanks a ton for sharing.

 
  • Looking for some open-source projects to start contributing .
  • Angular is on the way but React is best😍.

Getting Started

Set up is pretty straightforward. Check out our docs to get up and running.

 

Giving an attempt to working with Hadoop and Spark, really interesting stuff so far!

 

Learned to use Profiler (rbspy) in RubyMine, which helped me find what was slowing down my code (and it was - suprisingly - array.uniq taking waaay to long)

 

I learned more on Chrome dev tools and it has a dark mode.
