Wow! July 31st. See you tomorrow August!

It's that time of the week again for the first time this year. 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.๐Ÿ‘‡๐Ÿ‘‡๐Ÿป๐Ÿ‘‡๐Ÿผ๐Ÿ‘‡๐Ÿฝ๐Ÿ‘‡๐Ÿพ๐Ÿ‘‡๐Ÿฟ

I actually learned that you can add multiple lines to a git commit simply by pressing enter without the closing quote, it automatically moves you to a new line, over 8 years of using git, and I just learned it this week. ๐Ÿ˜Ž ๐Ÿ‘


If you enter just โ€˜git commitโ€™ itโ€™ll open your commit in nano. You can enter a brief commit message followed by as many paragraphs as you want explaining your commit.

Iโ€™m not sure if you can change your default text editor to use whichever you prefer.

  • tree-shaking
  • why tree-shaking wasn't working for me
  • why Webpack won't tree-shake a module that was already compiled to UMD by Webpack
  • why named exports and imports are important
  • why it's bad practice to mix named and default exports
  • why I should have separate outputs for my libraries (ESM, CJS, and UMD)
  • the difference between package.main and package.module
  • Rollup, and when to use it instead of Webpack
  • I also learned a little about golang earlier this week and I kind of want to go back to that.

Bundle tweaking for the win to make things blazingly fast.

I think you should write a post about this so we can all learn too!


My bosses value my productivity more than a little bit of money. They paid to upgrade our GitLab subscription sobi could get scoped labels and a few other features. It's easier to see what the status if somethingbactually is now.

Also, issue templates in GitLab. Encouraging me to write proper issue details instead of "this needs fixing" in the stupid belief that I'll still know what it means in a few weeks


Yup. And after a few days of scoped labels, I have no idea how anyone lives without them


That, if I keep practising things will get easier. Three months ago I used to struggle with easy leetcode problems. Now I solve 3-4 easy ones spending about 30mins a day. Also, that you start enjoying a new skills after you become better at it...


that computer graphics is really hardest !!! I wish there is a higher superlative degree than hardest !!!!


and that de.to works in a pretty strange way. My follower increased in rapid number back a few months and suddenly it downed to zero. I checked it today and it is still 1217. It is pretty fascinating.


Hardest degree was 10, but this kangaroo sets it to 11!

hahaha !!! your gif on reply on this thread every week is more than mood refreshing. Do you have any kind of experience in dealing with computer graphics?


I used git cherry-pick for the first time. I also learned the importance of QA testing features on feature branches, instead of merging it to master before being tested. Yes, these things were related... ๐Ÿ™„


QA is important but lesson learnt. ๐Ÿ˜„

I learned that there are several providers for hosting services that also offer the service of lambda functions so I can be uploading things I make and connect to DB's without an actual backend.

I've heard of serverless before but I didn't know that it was this easy and approachable to do....

Imagine the possibilities!!


I learnt about using Now / Vercel serverless functions.

I used them to write a couple of proxies. This allowed me to do my UK roadworks app without needing to re-deploy it each week when the new information is posted, and also facilitated writing an RSS reader (so last decade!).


I completed going through PWA concepts. Next is to have them implemented. I also learnt that sometimes the best things can happen at last minute. So it is always good to be consistent with patience.


I started making websites using React and mobile apps using React Native. Also moved from mobile to web for Flutter. Watched a few podcasts abt life as a programmer and some rants by techlead. And moved a little bit closer to my ultimate goal of becoming a game dev. You can lookup some of my work that I am organizing now here or in more detail here


I learned a lot about Cloud Computing. I'm studying for the AWS Practitioner Certification.

From clouding computing models to AWS budgets and billing to Global Infrastructure.

Having fun will continue learning over the weekend :)

  • Get tips for handling team as well as client
  • Stuck with chrome audio play issue with android app, finally, get some hack for that
  • Preparing boilerplate for the NodeJS project setup - Not done yet...

nothing more then this


I learned about Azure Relay and wrote my first ever service.


I learnt about Github API and built a small project using it along the lines of Githuv Visual Dashboard. gitgeek.netlify.app.

I used git cherry-pick for the first time and also learnt Git is way more vast than I thought and robust too.


I learned the difference between named exports and default exports


I started learn React Native this week. I make some clones of famous app in Brazil, like picpay.


I learn how to use cyber security approached for Distributed Energy Resource (DER).

And I'm planning to use Kali Linux to do penetration testing on DER testbed.


This week I learned that even when I make my life stupidly busy, I can still do my 1h of code a day (doing #100DaysOfCode rn). I also learned that if I want to move forward I need to start setting myself goals (to finish in a week for example). I also learned that self compassion works better than a whip, and things get more enjoyable and easier when you curb your overthinking and perfectionism.

Oh, and more practically - THIS (writing image descriptions w/o overthinking)

learn a lot about #arirflow and cloud computing with GCP.


I learned a lot of accessibility when implementing in my portfolio. I don't know why I was so scared of it before and how important it is.


I learn how to create React/Vue/Angular apps with routing and create some templates. In the next days Iโ€™ll learn about Svelte too.


This week i learning about fastify and mongodb
I dont learn more this week
Hope next week i can complete my last project and learning redist


To learn to pay to get experience help in problems that you are unable to solve. Like using codementor to help speed up and solve a tough problem that I had been stuck for months.
