🐈 Newsletter WoR #64: a new Ruby framework, better design conversations, adapting your terminal...
A monthly newsletter about Ruby on Rails and the web
In this issue, we talk about how the web is changing with generative AI, a new controller-less Ruby framework, we step into the shoes of a Chief Data Officer…

Web News 🗞️
🦅 Vultures Are Coming
Some are worried about the web’s business model: websites aren’t visited (so ads aren’t clicked) while content is pumped out by generative AI. Cloudflare for instance decided to unearth 402 Payment Required, and others are saying they can make a profit out of it.

🤏 News in Brief
Vercel acquired NuxtLabs. Look, if we also had raised 536 millions we would also make impulse purchases (or create a conglomerate). Just over a week later Nuxt announced its v4; no lazying around here!

🆕 Brut
A new Ruby framework is rolling into town, and it’s not MVC (*gasp*). Interesting fact: it’s using the Hippocratic License. We’ve never heard of this license before in a tech context, but it has ethical principles, just like its oath counterpart. Not sure that Meta will adopt this license for React though.

Rails Tip 💎
Contextual validation with :except_onIn Rails 8 you can now ignore a validation in one or multiple contexts, using :except_on.
class User < ApplicationRecord
validates :birthday, presence: { except_on: :admin }
end
user = User.new(name: "Ada")
user.save(context: :admin) # 👌 No validation error on :birthday✅ Compatible with :on to apply only in some contexts.
🎉 Very useful for adapting business rules according to usage contexts (API, admin, workflow, etc.).

🤖 The Terminator Will Never Stop
The book Empire of AI: Dreams and Nightmares in Sam Altman's OpenAI has gotten a lot of attention since its release in May. Its author warns of the dangers of generative AI due to the power of companies that develop it, and the impact that they have on the planet or in their negotiation with countries.

(Note: the interview is in English despite the French thumbnail and title)
💬 Let’s Discuss
Prior to the launch of a second edition, the first edition of the book Conversational Design is available as a free download. According to its author, better interfaces require better conversations to understand the users’ needs and vocabulary. All of this starts with thoughts written down, rather than through images.
✨ Conversational Design - Erika Hall
🤏 News in Brief
An article that starts innocently by asking how to organize books in libraries, which leads to presenting an algorithm and how it works. It’s a good introduction for our readers that aren’t developers, and it’s of course interesting for everyone else.

🎛️ Taking Responsibilities
An example of how a developer integrated AI in their workflow: first as a learning tool, then as a consultant, finally as an employee thanks to orchestration. There’s also a case study as a concrete example.
✨ From Executor to Orchestrator: My Journey Building with AI Agents - Kechie Anyanwu
❤️ It Doesn’t Have to Be One or the Other
Speed vs technical debt. The author—who started her career as a QA engineer—offers to move past this binary vision so that quality becomes everyone’s responsibility. This is done by building processes that allow teams to make conscious decisions.

💻 Making a Comfy Nest Out of Your Terminal
After getting frustrated by VSCode lagging with vim, and trying out nvim, the author now uses tmux with a few tweaks to make it work for them. But they’re thinking of moving to kitty, and we might join them since we follow mascot-driven development.

🤏 News in Brief
We’ve already featured Nadia Odunayo who develops The StoryGraph, a solid alternative to Goodreads (if these two names don’t ring a bell they’re apps that let you keep track of your readings for these ancient artifacts called books). We had missed her bi-weekly development diary though, so we’re sharing it now.
✨ The one-woman dev team diaries - Nadia OdunayoSame here, a podcast that we’d completely missed, but that has a new guest every month and discusses a wide array of topics.
✨ Women In Tech Podcasts - Hosted by Eva LettnerA little bit of system design doesn’t hurt (except when it’s a mandatory step in an interview process that already had 5 steps, thanks).
✨ Building a Billing Usage Recovery System - Kaavya AntonyFollowing Kechie Anyanwu’s article presented above, another example of working with coding agents.
✨ Autonomous coding agents: A Codex example - Birgitta BöckelerWe’re not sure if we talked about the popover API for HTML, but you can learn more about it in this article.

👾 How Does This Actually Work?
We always like articles that delve into old hardware. The Game Boy is positively retro now and it up brings delightful childhood memories like summer road trips spending hours catching Pokémon in the back of the car.

🐈 A Suffering Simulator
Okay we might be exaggerating but this game 1) has an email inbox interface; 2) has you start as a newly-hired Chief Data Officer and you have to make decisions that have an impact on budget, quality of data, company profit and reputation. Not stressful at all then!
