DragonRuby: A Ruby-Based 2D Game Engine— Targeting Windows, Mac, Linux, WASM, iOS, Android and even consoles, DragonRuby is an interesting variant of Ruby coupled with a 2D game engine, meaning you can create striking games or demos with a language you already know. Apparently DHH hadn’t heard of it, so we wanted to feature it again, especially as it’s available for free for the next 36 hours (though it is commercial).

Ruby's Default Parser Switches from parse.y to Prism— A few months ago, Kevin Newton asked if CRuby could switch to the new Prism Ruby parser, but Matz said there was still work to be done. It remains to be seen if this change will ‘stick’ for Ruby 3.4 this December, but if you’re running on Ruby’s master branch, you’ll be using it for now.

The 'Gilded Rose' Refactoring Kata — As If It's 2024— Victor never fails to engage in his writing, even when it’s pecking through a classic refactoring kata. Turning a mess of if logic like this into something easier on the eye is a common task, however, so it pays to practice it.

IN BRIEF:

• 📊 Developer analyst firm RedMonk has put out a Q3 2024 ranking of programming languages with Ruby at 9th place.

• 🛠️ JetBrains has opened its Early Access Program for RubyMine 2024.3.

Ruby-SAML 'Pwned' by XML Signature Wrapping Attacks— Even if you’re not using SAML (commonly used in SSO systems), a lot of apps are, and this vulnerability is particularly nasty. “Ignore Postel. When it comes to processing cryptographic signatures, loosey-goosey isn’t “liberal”, it’s libertine.”

Setting Up TOTP Two-Factor Authentication in a Rails App— Except for farming auth out to a third party service, using time-based one-time passwords (TOTPs) is probably the easiest way to add 2FA to your app.

Shrinking Big Postgres Tables with 'Copy-Swap-Drop'— If you’ve got a big unwieldy table with only a subset of its data in active use but you don’t want to partition the table or perform lots of DELETE operations, you could copy the rows you want to keep into a new table, rename the new table, and drop the original one.

RSpec Stubs the Object in Memory— Just because you applied a stub to an object doesn’t mean your underlying code will be using the same object, particularly if it’s loaded just-in-time from a database.
