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:

Most developers would agree that, all other things being equal, a synchronous program is easier to work with than an asynchronous one. The logic for this is pretty clear: one flow of execution is easier for the human mind to simulate than n concurrent flows.

After doing two small projects in node.js (one of which is here -- ready for the blinding flurry of criticism), there's one question that I can't shake: if asynchronicity is an optimization (that is, a complexity introduced for the sake of performance), why would people, a priori, turn to a framework that imposes it for everything? If asynchronous code is harder to reason about, why would we elect to live in a world where it is the default?

It could be argued pretty well that the browser is a domain that inherently lends itself to an async model, but I'd be very curious to hear a defense of "async-first" thinking for problems that are typically solved on the server-side. When working with node, I've noticed

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Python 2.x

$ python -m SimpleHTTPServer 8000

Install Active Record Mysql Bindings

gem install activerecord-mysql2-adapter

Add mysql2 to your .Gemfile

gem 'mysql2'

Configure your DB Settings in config/database.yml

development:
    adapter: mysql2
    encoding: utf8
    database: mysql_db_name

pool: 5

Node.js Resources

What is node.js?

Node.js is just JavaScript running on the server side. That's it. That's all there is to it.

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

install packages for vim, git
create user accounts, as specified in included JSON config files
install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	set :application, "My Static Content"
	set :servername, 'test.example.com'

	# no git? simply deploy a directory
	set :scm, :none
	set :repository, "." # the directory to deploy

	# using git? deploy from local git repository
	# set :scm, :git
	# set :repository, 'file//.' # path to local git repository
