Old trick for debugging outgoing requests in #Ruby. It's especially useful when you need to ensure that you're sending requests correctly to third parties by showing them the raw request structure.

#Rails

Instead of locking #Ruby in both .ruby-version and the Gemfile, you can read .ruby-version directly in the Gemfile:

ruby file: ".ruby-version"

#Rails

Too many memories

app: tty: true stdin_open: true

To debug a #Rails app in #Docker with #Pry, set stdin_open: true & tty: true in docker-compose.yml. Then, add binding.pry in your code and run docker attach <container_name> to interact with Pry in the container. #Rails #Docker #Debugging

Uma coisa que penso tbm, se a minha mala for extraviada ( eu consigo sobreviver com isso aqui)

Também meto AirTag em tudo para garantir

Small adjustments:

require 'sidekiq/api'

queue_name = 'low'
queue = Sidekiq::Queue.new(queue_name)

queue.each_with_object(Hash.new(0)) do |item, memo|
memo[item['wrapped'] || item.item['class']] += 1
end

Thos is a screenshot from a GitHub issue page under the repository golang/go. The issue is titled “encoding/json: unexpected json.Unmarshal behavior with maps” and was opened on October 17, 2015. It includes a discussion about the behavior of the json.Unmarshal function in Go when unmarshaling JSON objects into a map. The user ‘nsoufr’ initiated the issue and provided a description along with code examples illustrating how the unmarshaling behaves differently from what the Go documentation describes. They point out an inconsistency with the map being replaced by an empty map before key-value pairs are added, which doesn’t align with the documentation. The discussion in the comments section seems to revolve around clarifying this behavior and possibly updating the documentation to reflect what actually occurs in the code

The day I found an issue in the #Golang standard library.

Zero-downtime #Postgres schema migrations need this: lock_timeout and retries

Mais importante que ego e parecer super-star, é ter um time único com único foco em resolver problemas.

sempre escolha:
Resolver problema ao invés de Ganhar discussão.

#BolhaDev
#CarreiraDev

Afinal de contas, o time que está lá foi responsável pelo crescimento da empresa até agora. Já passei por situações no passado em que alguém entrava na empresa e dizia: ‘Na minha empresa anterior era assim’, mas nunca apresentava um caminho claro.

#CarreiraDev
#BolhaDev

Trabalhei em uma empresa por 10 anos, lá era Principal Engineer. Agora, fui para uma empresa bem menor, bem no começo da jornada.

Acho que a melhor dica que eu poderia dar nesse caso é não ser um cara chato, que chega e aponta que tudo está errado e que nada funciona.

require 'sidekiq/api' queue_name = 'low' queue = Sidekiq::Queue.new(queue_name) queue.each_with_object(Hash.new(0)) do |item, memo| memo[item['wrapped']] += 1 puts memo end { "ArtifactIndexerJob" => 817, "FieldJob" => 183, "WebhookJob" => 19435, "EmbeddingsJob" => 122, "UpdaterJob" => 526280, "EventCacheWarmupJob" => 140 }

Counting how many items the queue has per #Sidekiq Job.
#ActiveJob #Rails

$ docker-compose build \ --build-arg CONTRIBSYS_GEM_SERVER_USERNAME=$(op read "op://Shared/Sidekiq Pro - Contribsys/username") \ --build-arg CONTRIBSYS_GEM_SERVER_PASSWORD=$(op read "op://Shared/Sidekiq Pro - Contribsys/password")

This is how you build an image with credentials from a #1Password shared vault.

In this example, I'm passing the #Sidekiq private gem server credentials to be used on the image-building process for a #Rails application.

Tudo isso levando em consideração que você não conseguiu chamar alguém que entende dessa parte para um pair

Nessa situações o que mais funciona é quebrar o problema em partes menores, ex:
Tenta reduzir o escopo da olhando apenas para a parte do código que será afetada pela sua modificação, não necessariamente precisar entender o todo.

Escrever testes/ou ler os testes para essa área do software.

engraçado que tudo isso ai eu gosto muito heheh, nao sabia que a galera falava mal heheh.
