Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

Cross-compiling Rust from Linux to Windows using Wine

🔴 Note: this article is obsolete. This cross-compilation direction may just work out of the box. 🔴

0. Ensure Rust works on Host

Let's create a dummy project for a test.

$ cargo new test

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

	// Promise.all is good for executing many promises at once
	Promise.all([
	promise1,
	promise2
	]);

	// Promise.resolve is good for wrapping synchronous code
	Promise.resolve().then(function () {
	if (somethingIsNotRight()) {
	throw new Error("I will be rejected asynchronously!");

	#!/bin/sh

	KERNEL="/path/to/vmlinuz64"
	INITRD="/path/to/initrd.img"

	// Creating a node graph editor for Dear ImGui
	// Quick sample, not production code!
	// This is quick demo I crafted in a few hours in 2015 showcasing how to use Dear ImGui to create custom stuff,
	// which ended up feeding a thread full of better experiments.
	// See https://github.com/ocornut/imgui/issues/306 for details

	// Fast forward to 2023, see e.g. https://github.com/ocornut/imgui/wiki/Useful-Extensions#node-editors

	// Changelog
	// - v0.05 (2023-03): fixed for renamed api: AddBezierCurve()->AddBezierCubic().
