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.
#todayilearned
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.👇👇🏻👇🏼👇🏽👇🏾👇🏿

This week, I learned about this app called Muzzle, which hides on-screen notifications while I'm screensharing :)

Holy moly, thank you for this!
You can thank @joshpuetz :)
I learned how to build React with Parcel!
I wrote about the journey here.
I learned about C++ template specialization:
C++ Template Specialization - Syntax Note

I learn something new about C++ damn near every coding session, it seems. Huge language.
I took things lightly and made a simple meme maker application with React. Earlier I was using some fancy technologies/libraries in my e-comm project, this time around, I made this meme project with just React.
I learned a lot about surrogate keys in edge caching.
Alongside @rhymes and co we're getting a better handle on the caching infrastructure we use at DEV.

I've been working with BDD (Behavior-driven development) this week and I learned how to run e2e tests for an Angular app using Gherkin syntax. For this purpose I had to setup Protractor + Cucumber-js + Chai. At the end everything worked which was amazing 😀
I recently started a new job at a site you may have heard of, and have learned so much about their codebase and processes!
that's sound great, congratulations.
dev.to seems like a dream place to work!
I've learned about the importance and how to mesure Key Devops metrics.
I've also worked with Jenkins for CI.
🌼🌳🌱🌍I learned about the impact of digital services on the environment (us), and what I can do about it. I learned that majority of the impact is coming from building new devices (phones, PCs, tablets, connected cars) and that the way to reduce that impact is to design digital services which are optimized so that renewing a device because it is slow can be delayed.
This week, I got introduced to Elixir programming language and I wrote a function to calculate the factorial of a number.
I expressed my surprise at how you can calculate the factorial of 10_000 very fast on the post How to Calculate the Factorial of 10_000 - Elixir.
This is not possible in many other languages by the way... So it was a good lesson!
Sounds really cool. I haven't done any Elixir myself, but I know the folks at Infinite Red led by Jamon Holmgren do quite a bit of it. I found a brief post from him about moving to Elixir, shift.infinite.red/the-rails-doctr....
He's on DEV, but not really active at @jamonholmgren . He Tweets a lot, so give him a follow there too if you want.
Wow! Thanks.Will definitely follow him.
I learned that Tailwind CSS exists, and that it's fairly easy to set up, but that I probably need to practice UI/UX skills a bit more to make effective use of it.
But I'm excited to try! BootstrapVue works great for me when I'm not concerned about building a unique UX, but it never feels easy to customize Bootstrap to give a unique look and feel, even though I know it's possible.
It seems like Tailwind solves that problem, allowing you to gradually build your way up to reusable components over time.
If anyone here has good learning resources about Tailwind that they'd recommend checking out, I'd love to hear about them.
I too have been wondering if tailwind is worth the time investment for me to learn. I have the Tailwind playground bookmarked which seems useful because of the intellisense. I'm in the same boat in that I think a lot in terms of BootstrapVue and native CSS3, and I'm not sure how much I would have to unlearn things before I fully understand tailwind. And it's not completely clear to me if the benefit Tailwind provides is worth the benefits it throws away: like, I can use a class "border-purple-100" but not "border-purple-150"? Whatever used to be a laundry list in css just got moved into a laundry list of class names in the HTML. Also, the other big tradeoff to me appears that changing the entire theme of a given page will become much more challenging when using utility-first framework (i.e., the class names of each element will have to be tweaked). Maybe someone can convince me otherwise.
About changing the theme of a whole page, I mostly assume that I would be using utility classes to build reusable components in Vue, rather than directly using the utility classes everywhere.
So taking that approach, rewriting the theme for each component would then apply the styling wherever it is used.
learned graphene for python( django)
actually looking for graphql python and some best practice
I did a lot of react since last week!
And I discovered, since last year , React has changed a lot...
Everything in react is now a hook, and redux is not completed as I taught it’s!
I learn also about how to use docker to generate SSL certificates and how to use cronjobs in windows....
Nice Espoir! Yes, there are a lot of new things in React. One great article I'd recommend if you're new to hooks is this one by @wattenberger . Sidenote, great work on this article Amelia! 🔥
Thinking in React Hooks
Let me check it out...
Learn RxJava. Dagger2 is next
This week, I learned python and wrote api calls to Spotify to return information on artists such as top 20 songs.
