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 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 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 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.
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 learned how to build React with Parcel!
I wrote about the journey here.
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 😀
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 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 that if you inline
in your docker build script, you may miss these errors
E: Release file for ... is not valid yet (invalid for another 22h 2min 28s). Updates for this repository will not be applied.Which leads to other potential other issues.
So from now on, I'll put them on a separate lines.
