My answer to: https://www.reddit.com/r/Clojure/comments/pcwypb/us_engineers_love_to_say_the_right_tool_for_the/ which asked to know when and at what is Clojure "the right tool for the job"?

My take is that in general, the right tool for the job actually doesn't matter that much when it comes to programming language.

There are only a few cases where the options of tools that can do a sufficiently good job at the task become limited.

That's why they are called: General-purpose programming languages, because they can be used generally for most use cases without issues.

Let's look at some of the dimensions that make a difference and what I think of Clojure for them:

Magit forge for Gitlab in Doom Emacs

This guide assumes you're working on a Unix-like environment. I'm using Linux Mint (Ubuntu). It should work on Macs, and might on Windows.

These are the four steps you can use as a checklist, see the headings below for the details on each step.

Enable forge support
Create a Gitlab API key
Add your gitlab credentials to ~/.authinfo.gpg
Set-up forge in emacs

Want to do some ethical hacking with only a Raspberry Pi 3?

No extra hardware required! Follow these steps:

Download kali for raspberry pi & flash the OS onto the SD card
iw phy phy0 interface add mon0 type monitor
ifconfig mon0 up
*alternatively try: airmon-ng start wlan0

To hack wifi

Pull Request Process

Ensure any install or build dependencies are removed before the end of the layer when doing a

defprotocol: defines an interface
deftype: create a bare-bones object which implements a protocol
defrecord: creates an immutable persistent map which implements a protocol

Typically you'll use defrecord (or even a basic map);
unless you need some specific Java inter-op,
where by you'll want to use deftype instead.

Note: defprotocol allows you to add new abstractions in a clean way Rather than (like OOP) having polymorphism on the class itself,
