Jan. 31, 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.

Brain lifting weights saying knowledge is power

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 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.

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.

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.

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)

  • Correction: it's trivial for people who are much smarter than me :). I'm going at Homer Simpson speed on this one.

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.

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

what i have learned so far the last week

  1. Be a good listener trying to improve my listening skills
  2. Be proactive in discussions
  3. Must have clarity of the tasks before committing the timeline.
  4. Improved bit decision making in technical things ( by Reading a lot of practical use cases, scenarios, test cases, white papers, best practices )
  5. studied 30 articles including technical and nontechnical ( for self-development)
  6. Helped my colleague when he was stuck in Linux related task
  7. Saving a lot of time by planning each and everything instead of wasting time without planning for a whole week.
  8. I just got to know the maximum limit of reading books/technical articles Articles 10 per day, 15 pages/day.
  9. Just got to know that there is a weekly thread for What was Your win this week and will follow this weekly

Next.js headless e-commerce with BigCommerce. I am new to API and this week gone so quick with documentation :D

Hey mate, I just found this while looking into next.js & BigCommerce... how did everything go? I'm looking to setup something similar. If there was anything you found helpful please feel free to share. Thanks!

Well I am still learning, there was an update for next.js recently and they changes bits with getStaticProps so I had to rewrite a few things. Also I am using Redux and redux wrapper also has an update to version 6 so now I am trying to get it to work.
Fetching data is quite easy, I found an issue with product images because it's a separate API call and you have to merge it with products to show the images. If you have any specyfic question just ask and I may help you

I'm starting out with next.js ecommerce and BigCommerce. I have deployed the storefront to Vercel and cloned the project to my computer. I'm trying to figure out what steps to take next from here. Any tips or advice on the route you used?

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.
