“wow, I didn’t know the terminal could look like this.” 😅

this publication fits the moment perfectly. charm definitely belongs to ruby! I'm exited to test it out @marcoroth

recently, I've been amazed by the UK jungle culture and what makes something jungle. I'm excited to share my first jungle track and actually, my first track ever! ✨

if someone asks me “why linux?”

bc I'm the one in control; I can choose my desktop experience. want to look like Windows 98? that's possible too; no bloatware, no surprises; my data stays offline by default and no gossip behind my back; better performance

too late to talk about github’s recent absorption by micro$oft? that announcement definitely raised some red flags in my head

but it’s never too late for a good article. right?

_github is **not required**_

ignoring alternatives is risky. find a backup for your preferred tools

Hey gang, I really need a job. UK, remote, something to do with computers.

I've been doing all sorts of software plumbing for a decade now, I can speak C, Java, PHP, Python, JavaScript, HTML, CSS, even a bit of Assembly for certain architectures in a pinch.

I might not be extremely specialized in any one area but you bet I can solve that one nagging problem you're not sure what specialist you need for. I've done frontend, backend, embedded, everything.

Please boost!

TIL: about pure functions in functional programming

depends only in its inputs; same input = always same output; no hidden state, no side effects, immutable (return a new thing instead of changing state)

@marcoroth interesting! it was a big discovery for me and made me think about being more open-minded about my friction with typed languages. thank you for sharing this! is this part of the ruby core now?

TIL: ruby, a dynamically typed language, does benefit from static type checking

ruby type checking occurs in runtime; ruby 3 has .rbs files that contains the type information; it provides several degrees of type checking; you can use type profiler to detect type conflicts

ruby wants the benefits of static type checking and does so at some levels. it doesn't want declarations which, for ruby, are redundant, and instead abstracts them away
