Russian Terrorist Army has attacked my country. It is bombing my hometown (Chernihiv). It is threatening life of my family. My grandmother is in a village occupied by Russians. She has no access to food an help.

As a software developer, this might be one of the easiest things you can do:

🛑 Block access to your software to anybody from Russia IPs 🛑

block software from russia

Complete technological embargo.

If you’re running a Ruby on Rails app, it takes just one gem and one before_action to do:

bundle add geocoder

request.ip # => 233.543.123.235
request.location.country # => RU

# app/controllers/application_controller.rb
before_action do
  if request.location.country.eql?("RU")
    redirect_to "https://www.ukr.net/"
  end
end

Update: @rameerez has created a gem that blocks all requests from Russia.
