Programming Ruby 3.3

The Pragmatic Programmers' Guide

Ruby is one of the most important programming languages in use for web development. It powers the Rails framework, which is the backing of some of the most important sites on the web. The Pickaxe Book, named for the tool on the cover, is the definitive reference on Ruby, a highly-regarded, fully object-oriented programming language. This updated edition is a comprehensive reference on the language itself, with a tutorial on the most important features of Ruby—including pattern matching and Ractors—and describes the language through Ruby 3.3.

Better Know A Ruby Thing: Methods and Access Control (part 1)

I’ll be honest, I picked this topic out of the half-dozen or so Better Know A Ruby Things on my to-do list strictly because it’s maybe the only Ruby take that I genuinely argue with people about. To be even more honest, it got away from me a bit as I started writing the argument: which is why I tend to avoid declaring methods private. I know these newsletters have tended toward long, but 3100+ words was a bit much even for me, so I’ve split it in half.

Conway’s Law

If your organization has coders continually getting in each other’s way, or if you make a change to part of your code base and don’t know who needs to review it, or if you have code that nobody maintains because everybody owns it… you may be violating Conway’s Law. Hi – I thought I’d do something a little different this time. We’ll be back to more Better Know Ruby things next time, but I’ve been sitting on this essay for a while and wanted it to get out.

The Big Book Post for 2023

This is late even by my absurd standards for having this post be late. I have a good excuse – I got on to TikTok. And not that I wasted a bunch of time on TikTok, but that I started to see a lot of BookTok videos, where a lot of very earnest people would talk about their 5-star-books for November or whatever. And I thought, “Do I sound like that?

Better Know A Ruby Thing #5: Block Arguments

Previously in what what I guess is now “The Argument Trilogy”, we talked about: Positional Arguments Keyword Arguments And now the trilogy now comes to its inevitable conclusion with “Return of The Jedi” block arguments. In the interest of keeping this thing within the plausible word count of a newsletter, we’re not going to talk about what blocks are or the way blocks behave here, that’ll be a future Better Know, but we do need to talk about block syntax.
