Vibe code with your voice

Vibe code by voice. Wispr Flow lets you dictate prompts, PRDs, bug reproductions, and code review notes directly in Cursor, Warp, or your editor of choice. Speak instructions and Flow will auto-tag file names, preserve variable names and inline identifiers, and format lists and steps for immediate pasting into GitHub, Jira, or Docs. That means less retyping, fewer copy and paste errors, and faster triage. Use voice to dictate prompts and directions inside Cursor or Warp and get developer-ready text with file name recognition and variable recognition built in. For deeper context and examples, see our Vibe Coding article on wisprflow.ai. Try Wispr Flow for engineers.

Vibe code with your voice

Vibe code by voice. Wispr Flow lets you dictate prompts, PRDs, bug reproductions, and code review notes directly in Cursor, Warp, or your editor of choice. Speak instructions and Flow will auto-tag file names, preserve variable names and inline identifiers, and format lists and steps for immediate pasting into GitHub, Jira, or Docs. That means less retyping, fewer copy and paste errors, and faster triage. Use voice to dictate prompts and directions inside Cursor or Warp and get developer-ready text with file name recognition and variable recognition built in. For deeper context and examples, see our Vibe Coding article on wisprflow.ai. Try Wispr Flow for engineers.

A note from Lucian Ghinda, the curator of this newsletter.

We just reached 6000+ subscribers 🎉 To celebrate this milestone, we want to focus the next edition on Ruby Developer Experience. I want to create a comprehensive edition with tools and resources that improve the lives of Ruby developers.

If you know about any tool (gem, project, library, service, product) or resource (book, course, YouTube channel) or any other kind of project that improves the Ruby developer experience, please submit it here: https://github.com/ShortRuby/submit

A few things to keep in mind:

  • It is ok to submit your own project.

  • If you want to offer any discount for the readers, that is welcome too.

  • Rails tools/resources/books are of course welcomed (a Ruby on Rails developer is a Ruby developer)

Looking forward to your submissions.

84% Deploy Gen AI Use Cases in Under Six Months – Real-Time Web Access Makes the Difference

Your product is only as good as the data it’s built on. Outdated, blocked, or missing web sources force your team to fix infrastructure instead of delivering new features.

Bright Data connects your AI agents to public web data in real time with reliable APIs. That means you spend less time on maintenance and more time building. No more chasing after unexpected failures or mismatches your agents get the data they need, when they need it.

Teams using Bright Data consistently deliver stable and predictable products, accelerate feature development, and unlock new opportunities with continuous, unblocked web access.

]]> Five Ruby Links #3 First steps into game development with DragonRuby, discover Ruby's Smalltalk neighbors, Hunt a Ruby memory bug, See arguments against RSpec shared examples, and color Deterministic Mesh Dradient Avatars with Ruby https://newsletter.shortruby.com/p/five-ruby-links-03 https://newsletter.shortruby.com/p/five-ruby-links-03 Tue, 11 Nov 2025 13:53:32 +0000 2025-11-11T13:53:32Z Lucian Ghinda

If I were to recommend five articles published last week to read, here is what I would recommend:

1️⃣Julian Rubisch published a new article about An Introduction to Game Development with DragonRuby

This is a great exploration about how Ruby can be used outside of web apps and I always wanted to try Dragon Ruby. This post gives you enough information to get you excited to have fun with Dragon Ruby.

Source: An Introduction to Game Development with DragonRuby

2️⃣ Noel Rappin published a new article about Ruby And Its Neighbors: Smalltalk

I liked very much to read this exploration about Smalltalk and understand more from Noel who used it professionally. It covers ome very nice innovations that Smalltalk had and this deep dive into Smalltalk helped me understand more about what Ruby borrowed from there.

Source: Ruby And Its Neighbors: Smalltalk

3️⃣ Maciej Mensfeld published a new article about When Your Hash Becomes a String: Hunting Ruby’s Million-to-One Memory Bug

This reads like an professional investigator looking at a very suspicious problem and taking us along the way. I enjoyed going with Maciej on this trip and finding clues along the way and learning a bit more about Ruby memory model.

Source: When Your Hash Becomes a String: Hunting Ruby’s Million-to-One Memory Bug

4️⃣ Jason Swett published an article about RSpec shared examples unmasked

Jason goes over BetterSpec recommendation for using shared examples and builds up an argument for why in testing DRY might not be a good principle to follow.

Source: RSpec shared examples unmasked

5️⃣ Avo published a new article about Deterministic Mesh Gradient Avatars in Rails

Avo continues to publish on their blog deep dive good tutorials and this one is no exception. Using ChunkyPNG and a bit of math you will generate some very nice mesh gradient avatars with Ruby.

This was started by a feature request made by Xavier Noria who made very good arguments for renaming namespace to something else:

The proposal that was finally accepted by Matz was suggested by Satoshi Tagomori:

Source: https://bugs.ruby-lang.org/issues/21385#note-26

What could be interesting to keep in mind from that conversation is that Matz noted:

FYI, I consider this namespace thing as a low level API. And I have a plan to provide higher level API in the future.

]]> Five Ruby Links #2 Find out everything about frozen string literals from Jean Boussier, parsing Ruby code from Pat Shaughnessy, code highlighting in Rails from Avo, single-purpose classes from Szymon Fiedler, and a zero-downtime database migration from Denis Lifanov https://newsletter.shortruby.com/p/five-ruby-links-02 https://newsletter.shortruby.com/p/five-ruby-links-02 Tue, 04 Nov 2025 08:21:32 +0000 2025-11-04T08:21:32Z Lucian Ghinda

If I were to recommend five articles published last week to read, here is what I would recommend:

1️⃣ Jean Boussier published an article about Frozen String Literals: Past, Present, Future?

This is a very good deep dive into frozen strings, the history of the feature, and how it got implemented in Ruby, and what the possible future plans are with it.

Source: Frozen String Literals: Past, Present, Future?

Make sure to also read this amazing Gist “Ruby: The future of frozen string literals” written by Xavier Noria. If you read these 2 resources, should know everything there is to know about frozen string literals in Ruby.

2️⃣ Pat Shaughnessy published an article about Parsing: How Ruby Understands Your Code

This is a great article that shows how the Ruby parser is going through the source code and it takes you through a journey about how Ruby makes sense of the syntax and the internal representation of it.

Source: Parsing: How Ruby Understands Your Code

3️⃣ Avo published a new article about Code highlighting with Rails

Again a very good tutorial from Avo about how to configure code highlighting in Rails. A lot of projects/organisations have technical blogs that can be built using Rails and it is great to see various ways of how to show good syntax highlighting:

Source: Code highlighting with Rails

4️⃣ Szymon Fiedler published a new article about The Joy of a Single-Purpose Class: From String Mutation to Message Composition

Szymon here discusses fixing deprecation messages related to string mutations and demonstrates an OOP refactoring focused on simplicity and efficiency.

Source: The Joy of a Single-Purpose Class: From String Mutation to Message Composition

5️⃣ Denis Lifanov published a new article about Migrating Whop from PostgreSQL to PlanetScale MySQL with 0 downtime

Denis from Evil Martians writes a very good article about migrating from PostgreSQL to PlanetScale MySQL for Whop. It shows the step by step process of migrating 750GB of production data while also keeping the development of new features running and without any downtime to the users.

💻 Code Samples

[This is an ad from the curator of this newsletter]

Hello, Rubyists!

If you love coding but sometimes find writing tests to be a chore, I have something for you. My upcoming workshop (happening on Friday, 31 October from 16:00 UTC) focuses on using AI to help you generate reliable test cases.

Join https://goodenoughtesting.com/learn/reliable-test-case-generation-with-ai

However, this isn't just about relying on AI to do everything for you, it's about understanding the process. We'll explore which aspects of testing can be safely and effectively delegated to an LLM (large language model) and which parts you should continue to handle yourself.

In other words, it's about finding the right balance. You'll learn how to let AI manage the repetitive or standardized testing tasks, allowing you to concentrate on the interesting and fun aspects of your code with confidence. If this sounds appealing to you, come join the workshop!
