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.👇👇🏻👇🏼👇🏽👇🏾👇🏿

git checkout -checks you out on your previous branch 😁🥳
I attended a lecture, and the delivery was so bad that I learnt nothing about the content. But instead, I learnt so much about 3 things I shouldn't do when I am teaching in future.
Problem: The slides are unintelligible.
What I learnt: Slides are visual aids that can enhance our presentations; they can increase the audience's understanding of the topic, explain points, and make an impact. I can do a better explanation with an illustration or just simply a sequence of text description explaining how each step works.
Problem: My lecturer assumes we know everything that was taught in class. I am not sure about the other students; for some parts, I was lost, for some parts, I regarded it as not necessary.
What I learnt: If I were to teach, I need to prepare content that is relevant to my class. My students may not understand why they need to know this topic; I need to tell them and show them, why this is good for them to know. Other than for the purpose to pass the exam.
Problem: My lecturer asked the class “any questions?” And answered right away, “no, good.” And I see students in front of me, giving the “what?” hand gestures.
What I learnt: I want my class to understand. I have to set an environment that is safe for questions. I don't have to rush through the content. I can ask for a show of hands to check their understanding.
I wrote What I’ve learnt from a lecture today about teaching to serve as a reminder for myself and to share to anyone who is currently teaching.
just basic docker 😁 and deploy my app into it
Hi everyone,
This week I'm migrating system with UI with HTML and JS to react.
Requisites: implement unit tests (TDD and BDD), keep the code clean.
I never developed anything in React, so it was kinda hard to do this task and I still have to implement the tests.
I learned a bit more about the mp4 atom structure. Even changing metadata is not such a trivial* task. (yeah, I know there's ffmpeg but...I'm a dev, I wanted to try what they do for various reasons)
With the help of our security team we deployed a Kubernetes service account that inherits access from an AWS IAM role. Instead of using static access/secret keys deployed to our secrets store we're able to allow temporary access to AWS resources.
Working through my content for first workshop and regarding myself on how to explain the concepts simple way 😅

You can build docker containers
FROM scratch!Did you?
Yep! Granted, it's straightforward when your whole application can compile to a single statically-linked binary. I just didn't even know this was an option.
If you're running a server that's running port mapper service and is listening on port 111(Proxmox by default), make sure you won't expose it to the public internet. Your server may be exploited and used in large DDoS attacks.
I learned how to create pages on Next.js based on metadata and edit a template page (written in handlebars) to autogenerate pages with the info I want them to have. Also messing around with the
