June 19th, 2020: 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.

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.👇👇🏻👇🏼👇🏽👇🏾👇🏿

I started working on tsParticles 1.17.0 and I created a particle mouse trail effect for that version

A preview can be seen here

I started working on an editor based on dat.GUI, it's a love-hate relationship because sometimes it's a bit tricky.

A preview can be seen here


Lerna is now working fine, I can say that I finally learned using Lerna and it's awesome!

Learnt the basic of AWS, terraform, and learnt about Stack data structure. Also practised questions on leetcode and codeforces. Started working on a side project to implement all that I learnt in AWS. :)

Surreal number is the largest number system where you use only the axiom of sets and one axiom of "less than" to construct numbers. Each number is constructed by putting together two sets, left and right, of which any number in the left set is less than those in the right set. Zero has empty sets for left and right. It contains real numbers, ordinals, and more. John H. Conway (of Game of Life fame) first discovered it when studying Go as a mathematical game. Donald Knuth (of TeX fame) gave it the name "surreal number" and wrote the first book about it in six days on a vacation with his wife.

I learned a lot about the Fulcro 3 framework (which is bound to happen since that's what we create our new product at work with) and am pretty much in love with it. And I learned more advanced ways to query and insert data with Datomic.

In my day-to-day duties this past week, I learned several new things about Elasticsearch, learned some new SEO insights, and learned a lot more about CSS utility classes.

Mostly just by following the leads of my co-workers at DEV and gaining insights from their different expertise.

I'm curious.. I've been learning a lot about Elasticsearch in the past 6 months. Mainly managing the cluster vs querying etc. What have you been doing with Elasticsearch?

Found a number of great, really sharp solutions for Dev.to.ol

  • A one liner to remove whitespace from article tags
  • unnest_wider is the most simple way imaginable to turn Dev.to API response into a rstats data frame
