Ruby 3.3 Preview 2 Released — With Christmas Day as the traditional day that new versions of Ruby land, things begin to pick up in the fall. Major performance improvements over 3.2 are already on offer thanks to ongoing improvements with YJIT, but there’s also an optional experimental pure-Ruby JIT compiler called RJIT to try.

'We Turned Lobste.rs into a Benchmark for YJIT' — Related to my comments (above) on how YJIT is continuing to get faster and faster, Noah Gibbs has some real world data on just how well YJIT, the default JIT in CRuby, optimizes Rails apps. The ‘real world’ scenario is formed by testing against the Ruby-based code that runs Lobste.rs, a Hacker News-esque social link aggregation site.

Fully Managed Postgres + Great Support — "What a different support experience Crunchy is. Not only is it timely, it's informed, it's on topic. We’re encouraged to ask questions. We’re able to do so much more working with a partner who cares as much about data as we do." Rob Sullivan, CareRev.

Rails 7.1 Beta 1 Released — It looks like things are gearing up for lots of Rails 7.1 news (and perhaps even a release) at the forthcoming Rails World 2023. This beta puts you on the cutting edge with support for the Bun JavaScript runtime, a new perform_all_later Active Job method for scheduling jobs en masse, support for composite primary keys in AR, improved async query support, and Dockerfile generation for all new apps.

Rails Middleware: (Almost) Everything You Need to Know — Akshay continues his run of posts digging into various facets of Ruby and Rails with a look at the use of middleware, a concept introduced by Rack but for which Rails has added a lot of sugar and helpers.

Akshay is blogging faster than we can link to him, as he's also written The Complete Guide to Working with Cookies in Rails which also goes into a lot of depth.

🎙️ Off the back of some.. kerfuffle about DHH's recent decision to yank TypeScript out of Turbo, DHH has appeared on the Rework Podcast to talk about the incident and share his characteristically punchy take on his role.

🙈 Over on Twitter/X, DHH stood up for Rails by 🐦 pointing to all the companies that have grown large using it. This provoked a flurry of discussion, mixed between replies suggesting some of those companies have since migrated away from Rails and people supporting Rails' success. It's certainly been interesting..

🎙️ Shami Tomita and Eric Halverson went on the Ruby on Rails Podcast to ▶️ discuss the building of the Rails World web site.

📅 In other event news, don't forget RubyConf 2023 is this November in San Diego, CA – tickets are still available.

🤖 Meanwhile, next month I'm headed to the AI Engineer Summit in San Francisco. Say hi if you're going! You can still apply to attend or grab a free remote ticket if you want to see what's up.

When Counting Lines in Ruby Randomly Failed Deployments — Sometimes the obvious or idiomatic way to do something can be quite inefficient under the hood, as in this case of using str.lines.count to count lines in a string. Luckily, there was a much faster approach..

How to Improve Rails Caching with Brotli Compression — Improving cache performance can be a game changer for larger apps, so better compression and a strategy that intelligently includes an in-memory cache is worth checking out (or you can just slip Rails Brotli Cache into your app).

re2 v2.0: Ruby Bindings to the RE2 Regular Expression LibraryRE2 is a fast, thread-safe regular expression engine built by Google (and used in products like Gmail) that, notably, avoids recursive backtracking by using finite automata-based techniques (Russ Cox has an article about this). Note that the regex syntax is slightly different to PCRE. As of v2.0, the Ruby gem includes vendored versions of RE2 so it can be installed more easily. Docs.
