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

I found out about key-tables in tmux.

Funny thing, I basically have no space for keyboard shortcurts when using tmux so... key-tables to the rescue. This is like a hacky way of having yet another "prefix key" which can trigger another set of actions.

For the moment I only have one custom key-table with two shortcuts.

# Ctrl+b changes the key-table to `x2`
bind -T root C-b switch-client -T x2

# `Ctrl + b` then press 1 to go the session with the name main 
bind -T x2 1 switch-client -t main

# `Ctrl + b` then press 2 to go the session with the name pomodoro 
bind -T x2 2 switch-client -t pomodoro

I'm continuing to learn Rust. I stream on Twitch if anyone is interested in learning with me at livecoding.ca. If you can't make the streams, I polish them and post them to YouTube, youtube.iamdeveloper.com.

Here's the latest one!

How to build a server work queue on my own. I knew what they were and why you might want one, but I’d never had to stand one up from zero by myself before.

I’m curious which npm package it is and which dependency?

Alright, ready for this? So, it's a dependency of


  (I was adding TS types to our npm package: https://www.npmjs.com/package/cumulio) And dts-gen has

 ```yargs-parser```

 as a dependency. But that dependency is being flagged as vulnerable. And you can't fix it via npm audit because it's a dependency of a dependency. Seems I'm not the only one in this pickle, found many more: https://github.com/JeffreyWay/laravel-mix/issues/2389

BUT, since my types are already created now I think I can just remove dts-gen from my dependencies and call it a day? Not sure.. And then.. I gotta figure out how to upload a new version to npm πŸ˜‚

I've come to the world of web dev from a low level C++ developer background and most of the time it feels like a breath of fresh air... Until NPM hits you with this πŸ’© still learning... :)

I learned more about RESTful and HTTP methods, and how to change (and split) my controllers so they are more RESTful (and more readable and better structured).

I was inspired by this article to refactor my controllers. And I'm quite happy about this - every controller is short, concise, it led to some more refactoring and fixes I overlooked in my old messy controllers.

In AWS you can get fractional GPUs using Elastic Inference which is hardware device you can attach to a EC2 CPU based instance. Save so much money not having to use an EC2 GPU instance.

I learned the definition of a closure in Golang-- they are anonymous functions that use at least one variable defined outside of the function.
