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
require 'net/http' module Net class HTTP alias_method :initialize_without_timeout, :initialize def self.enable_debug! # raise "You don't want to do this in anything but development mode!" unless Rails.env == 'development' class << self alias_method :__new__, :new def new(*args, &blk) instance = __new__(*args, &blk) instance.set_debug_output($stderr) instance end end end def self.disable_debug! class << self alias_method :new, :__new__ remove_method :__new__ end end end end Net::HTTP.enable_debug!

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

github.com/golang/go/is...
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

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.

More info:

$ 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")
