February 19th, 2021: 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.

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.πŸ‘‡πŸ‘‡πŸ»πŸ‘‡πŸΌπŸ‘‡πŸ½πŸ‘‡πŸΎπŸ‘‡πŸΏ

I used GitHub Actions for the first time - sooo easy and good! Why have I not used this before?!

I guess what I meant is I was able to get 2 GH actions up and running successfully in far less time than if I were to have set up Jenkins from scratch with auto scaling nodes etc etc - certainly I’m sure it gets complicated the deeper you go!

In any case you are right as it’s a poor choice of words - what I found easy, others might not (and vice versa). We are all at different stages in this life long journey called software development :)

I’ve played with ClickHouse β€” it’s a fast open-source analytical column-based database, and by fast I mean BLAZINGLY FAST. It’s also very developer-friendly: for example, It has something like REPL on its website that you can instantly try and use. And I actually wrote a guide about building an analytical dashboard with ClickHouse! Here it is:

I've been playing around with repl.it since I found out you can use it to deploy web servers. This means that is basically like a "full stack codepen".

I learned how to setup a tiny web server with 6 lines of code*.

(*) not counting the dependencies.

// index.js

const router = require('find-my-way')();
const static = require('serve-handler');

const assets = (req, res) => static(req, res, {'public': './public'});

router.on('GET', '/hello', () => 'Hello!');
router.on('GET', '/*', assets);

module.exports = (req, res) => router.lookup(req, res);
Enter fullscreen mode Exit fullscreen mode

And 1 command.

node_modules/.bin/micro -l tcp://0.0.0.0:3000 index.js
Enter fullscreen mode Exit fullscreen mode

Ok, technically you need to install things first. That'll be 2 commands.

npm install micro@9.3.4 serve-handler@6.1.3 find-my-way@4.0.0
Enter fullscreen mode Exit fullscreen mode

There you have it a (useless) web server with a fully functional router and capable of handling static assets. Here's a more exciting example in repl.it: micro-quote-machine.

I'm slowly but surely getting my head around WebGL. I've been using 2d context for a while but needed to do some equirectangular projection maths, which was painful on the cpu, and foolishly thought, 'how hard can it be?'.

I've converted existing VueJS SPA into Android apps with CapacitorJS. The guides was easy to follow and the application is working good. Just need to change the icons and enable camera for file upload.
