👐 Our Community

💎 We are celebrating Ruby's 30th birthday. There are so many great tweets about Ruby that for me was very hard to choose something to put here and putting them all would have made this newsletter almost infinite.

You can read them all on Twitter or on Mastodon

Here is a short history piece about naming the language:

👋👋 I'm very excited to announce Friendly.rb, a new Ruby conference I'm organizing in Bucharest, Romania on 27-28 September 2023.

With a focus on community, Friendly.rb is keeping it cozy with 100-ish attendees and some of the best European speakers. Our CFP is open until April 1st. As a speaker at Friendly.rb, you'll have the opportunity to connect with like-minded developers, share your expertise with a curious audience, gain valuable exposure in the Ruby community, and some perks from us.

👉 Nate Berkopec shared a tip about how to manage jobs:

👉 Postmodern shared the difference between URI.regexp and URI.parse

👉James asked a question about ways of handling error responses from a third-party API:

Here are some of the responses:

A code sample showing how to use Dry::Monads and Date.define to return status from a HTTP client — Source: @lucian@ruby.social

👉Paweł świątkowski shared their findings about what slows down testing Hanami apps:

An issue was reported out of this to faker: Speedup require and first call #2719 and it seems that the most time is consumed in parsing fakers translations.

Another proposed solution was to use transactions for cleaning. See example of how to do this in the decafsucks/decafsucks repository.

👉Postmodern shared a microbenchmarking about testing value != nil vs value.nil?

The possible explanation for this seems to be (rb_true and rb_obj_not_equal from Ruby source code)

It also seems that nil != value is almost close to value.nil?

👉Noel Rappin shared a TIL about string unary operations - and +

For more details Ryan Big shared the commit where these methods were implemented and Patrick de Heus confirmed that unary minus is aliased as dedu. You can read about the proposal of aliasing it by reading the Alias String#-@ as String#dedup on Ruby issue tracker.

Here are some other proposals from the discussion, but it is worth reading them all:

👉Emmanuel Hayford shared a code sample showing how to organised jobs in bulk in Rails 7.1

👉Luca Guidi shared a thread showing how to setup Hanami with Sidekiq. Here is one of the steps showing how to configure a sidekiq provider:

👉 Andrea Rocca shared a series of thread about Hotwire:

👉Nate Berkopec shared that configuring too many threads in Puma might increase average latency:

👉Greg Navis shared a thread about how to make a method recognise when it was called with no arguments vs when it was called with arguments set to nil (when arguments are passed vs when they are not passed):

👉Matt Swanson shared a code sample showing how to use validation scopes in Rails:

👉Stanislav (Stas) Katkov shared a thread about doing performance optimisation for Rails test suits:

It is worth looking at the code Stanislav shared on Github

👉Jeremy Smith shared a take about using Rails controller as service objects:

The entire conversation is good to read exploring various ways to organise code in Rails controllers. Here are some of replies:

👉Xavier Noria started a conversation about using constants vs global variables usage

Here are some ideas from the conversation:

👉Nate Berkopec shared about Rails memory usage:

Sam Saffron added:

👉Lucas The Dev reminded us about with_options feature of ActiveSupport:

👉Nate Hopkins reminded that there are a lot of advantages to invest time in proper designing ActiveRecord model layer:
