Mar. 13, 2020: What did you learn this week?

Service workers. A little bit complicated with their 3 step lifecycle, but fairly nifty. Mostly from the Google developers service workers primer

Finally succeeded doing an interactive rebase! I used to just trash a branch and create a new one. This time I actually read and understand how it works.
Nice article: blog.algolia.com/master-git-rebase/

A lot on HTML 5 canvas and javascript. How to uncover an object under a canvas or how to rotate the objects correctly.
These are the samples of what I'm talking about 💪:

Well, it's kind of weird saying that but I've been working with JavaScript for a while and yesterday I had to write a class. I had actually never written one in JS, mostly doing functional programming. The task at hand just felt more natural using a class.

So I learned about the intricacies of class variables, properties and methods. I got a lot of "unexpected..." or "undefined..." errors until I got the syntax right. That first JS class tutorial I looked at had a lot of errors in it. lol

I also found that I had to be careful about the syntax of a callback passed to findIndex (for arrays). I wasn't getting any error but always got a -1 result until I found that the syntax there was... hmmm... a bit simpler than what I've been doing for things like event listeners.

All frustrating at first, but in the end it all worked and it's a win. :)

I updated the social card generator on my gatsby blog website so that two separate images would be automatically generated - one each for Twitter and DEV (since they have different dimensions). I also made so that you could pass in an image URL and it would use it as the background:

I followed this tutorial here if anyone else is interested in adding it to their gatsby site!

Learnt Wepack and how does it work

I just started in a new company this week. I have just transitioned from functional business analysis to data analytics and data warehousing. I am just learning how the data is structured and starting a new project in Python, SQL and Airflow with BigQuery.

This week I learned Pure components in react and wrote below article about the same.

Pure Components in React

Ruby on Rails! Decided to take the plunge and start taking the BE stack we use seriously this year. 💪💪

I learned...

1. a little bit more about python for machine learning through Kaggle's mini-courses.
2. that I'm quite fortunate that my work allows me to work from home 100%.
3. that my soft skills need a great deal of improvement.
4. the critical importance of reading classic literature. You would be amazed at how relevant are the writings of Plato, Suetonius, and Nietsche to modern society. I was.
5. that freelancing is a job in itself apart from the actual billable work.

Typography! Some really great study on design theory, a professional mindset to typeface selection, and pairings.

And Sketch! I know Figma is where design is trending, but Sketch seems like a perfect starting point.

Some object-oriented design patterns, by browsing Github open source :)

I wrote two article on javascript that is available on my profile. Tried to learn new programming language RUST but left it with lack of fire 🔥🔥🔥🔥

• Work with docker first time
• AWS cognito
• Jenkins pipelines

This work I worked on to write two articles on Javascript.

dev.to/voralagas/that-s-it-knowing...

and

I tried to learn RUST and write some code in RUST along with writing articles in RUST.
