Sync Scroll: A VS Code Extension to Scroll Split Panes Simultaneously — This isn’t a language specific thing, but I found it useful this week when doing a manual (non diff) comparison of two files.

A Single File Rails Application⁉️ — We’ve seen this before, but willing to bet there are plenty of people out there that haven’t. It’s a neat experiment, but also a good learning experience.

Ruby 3.2 Introduces Regexp.timeout — This helps to mitigate problems around regular expressions that take a long time to process. Original discussion here.

Naming Things is Hard — Named after an oft-quoted developer maxim, this post focuses on what not to call things in Ruby, lest you unintentionally break something that was already there.

Announcing Incident Management For Honeybadger Status Pages 🤩 — Now you can report incidents in real time (or retroactively) and schedule alerts for planned maintenance. Check it out.

'How We Use Authorization as a UX Tool' — A look at how one team works with Pundit, an OO oriented authorization library, to improve end-user experience.

How to Generate Sitemaps for Hanami Apps — While this tutorial is focused on Hanami, sitemap_generator is a framework agnostic library.

▶  Setting Up Ruby on a Modern Ubuntu Desktop — Takes the RVM approach. (Other approaches exist, including asdf and rbenv).

The Active Record Playground Runner — This is an interesting idea. Benito is working on a tool that will let you play with Active Record to show off or test ideas without attaching it to an entire webapp. It’s early days but this is a cute idea.

Shale 0.7: Ruby Object Mapper and Serializer for JSON, YAML, TOML and XML — You can now specify whether or not to render nil values, amongst other things.

Faster Ruby: Thoughts from the Outside — Earlier this week, the author wrote an interesting retrospective on Ruby+OMR, a now-abandoned 2015 effort to boost Ruby’s performance via OMR, but has now moved on to thinking about how he’d approach making Ruby faster these days, taking some lessons from JavaScript. Hacker News ended up with a lengthy discussion on this topic, too.

Karafka 2.0: Multi-Threaded Kafka Processing Framework — This huge release has some big-time features such as multi-threading, Active Job support, and “virtual partitions” for concurrent processing of messages from a single partition. There’s now also a Sidekiq-esque Pro commercial option if you want to support the project. GitHub repo.

Free eBook: Advanced Database Programming with Rails and Postgres — Learn about subqueries, materialized views, and custom data types in Postgres and Rails. We walk through realistic real-life examples, translating first into SQL, and then into Rails code. Every example comes with source code so you can follow along.

A Further Dive into Memory Leaks in Ruby — We linked to the first post in this series two weeks ago; here’s the promised follow-up that goes into several tools and techniques to actually track down leaks.

From Byebug to ruby/debug — A cross between an introduction, cheat sheet, and direct comparison with how Byebug and Ruby’s newest debugging tool work. Very useful.

How to Take Screenshots from Rails Apps — Covers four options: Puppeteer with Goover, Cloudinary with URL2png, html2canvas, and Urlbox (the source of the article).

Tomlib: Fast, Standards-Compliant TOML Parser and Generator — TOML (named after inventor Tom Preston-Werner) is a simple config file format that’s reminiscent of INI, but better. This library boasts big performance wins against existing Ruby options.

NaturalDSL: An Experimental DSL for Building DSLs — How meta! To be fair, the creator says this is currently “highly likely useless” but the example was interesting enough to catch my eye. A step too far? Perhaps.

Fixed Price Monthly Code Maintenance for Rails Apps — No time to do those small, but critical updates to improve your app? CodeCare will take care of necessary tweaks, bug fixes, upgrades and ongoing improvements.

HexaPDF 0.24.0: PDF Creation and Manipulation Library — The focus in this release is on document layout. There’s also new support for creating column and list boxes – see the screenshots here for examples. Note: AGPL licensed, with commercial options available.

Comma 4.7: CSV Generation Extension for Ruby Objects — Define an output format in a basic DSL then easily create CSV from arrays, Active Record objects, etc. Example code here.

Grover: Transform HTML into PDFs, PNGs or JPEGs — Worth a look for the fantastic ‘logo’ alone 😆

Faraday 2.4: A Flexible HTTP Client Library — I’m still on team http.rb for my HTTP client work, but Faraday is a very compelling alternative (example usage) as it takes a higher level approach in offering a common interface over many adapters and embraces the concept of middleware for processing the request/response cycle.
