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.

Nice!

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.

I learned that when there's a dependency issue because of another dependency you have in node...It's NOT easy to fix.. I need help! And some hot chocolate 😢

Nick Taylor • May 18 '21

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

Tuana Celik • May 18 '21

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 😂

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 💩 still learning... :)

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.
