February 19th, 2021: What did you learn this week?

Nothing special.. One more week of my job and I leave them for work at my projects and upgrade skills on NuxtJs and Co, MySQL and NodeJs.

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

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?'.

Learnt Pandas dataframes. Am still curious how dynamically typed languages let their caller know about its functions.

Write elegant e2e tests for .NET Core web API.
Be kind!

I'm leaving learning CSS animation and sharing with our community check out my dev account 🔴

I recorded a podcast on accessibility and learned a lot!

I learned how to do manage files with Flask and also how to use some JS APIs.

My two completed projects are:
code-crystals.tk
irisor.cf

I had used location service in my own Android app using Java.
And I had completed 100 Problem solved in LeetCode and I'm really happy for that :)

I’ve played with ClickHouse — 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:

#webdev #database #javascript #tutorial

I am (belatedly) working on the #100DaysOfGatsby challenge, and learned how to use StaticQuery!

How to create buffers and splits in Vim. I made some notes on my findings in my TIL repository here.

I did my first Dockerfile 👌💪

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);

And 1 command.

node_modules/.bin/micro -l tcp://0.0.0.0:3000 index.js

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

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.
