Don't use the standard RSpec matchers with Capybara objects - the standard matchers don't have waiting/retrying behavior. Instead use the Capybara provided matchers

puts "visitando a pagina"
visit "https://www.google.com/"

I want to download video files from youtube.com, according links from my database.
I found gem viddl-rb, but I see only console way to download in documentation - viddl-rb youtube.com/watch/myvideoid
How to download video, using require viddl-rb in console?
Please be warned that it may be against Youtube's ToS to download videos from Youtube; but anyways, following code might help you do it:
require 'open-uri'
require 'viddl-rb'
YouTubeLinks = %w[
https://www.youtube.com/watch?v=Z8wLQ3NCBgg
https://www.youtube.com/watch?v=QH2-TGUlwu4
]
youtube_hashes = YouTubeLinks.map do |link|
ViddlRb.get_urls_names(link).first
end
youtube_hashes.each do |yt|
puts "Downloading: #{yt[:name]}"
File.open(yt[:name], 'wb') do |video_file|
open(yt[:url]) { |video| video_file.write video.read }
end
end

I'm trying to edit in column selection mode on Rubymine but I have some lines I wish to skip.
In the code below I would like to edit both "to_change" at the same time.
I wish to duplicate the cursor and every edit action will occur in them both.
In this code if I will select the start of both "to_change" and press '#', the code here:
def a
to_change
end
def b
to_change
end
will turn to
def a
#to_change
end
def b
#to_change
end
Multiple selection/editing is not supported yet, you can follow this feature request.

Is there a gem or another easy way to get time difference compare to present time like Twitter?
Of course I can write it myself, but I don't want to reinvent the wheel.
If you are using rails, you could do
distance_of_time_in_words_to_now #user.created_at
#=> "15 days"
or
time_ago_in_words #post.created_at
#=> "about 13 hours"

While learning Ruby, I got stucked with unless statement. Doing a full unless statement is sometimes too much. Please refactor the method below to use a single-line unless statement
games = ["Super Mario Bros.", "Contra", "Metroid", "Mega Man 2"]
unless games.empty?
puts "Games in your vast collection: #{games.count}"
end
This code doesn't changes the unless statement to be inline, Please help me to modify this code so that it may work, Thanks.
use then
games = ["Super Mario Bros.", "Contra", "Metroid", "Mega Man 2"]
puts "Games in your vast collection: #{games.count}" unless games.empty?
# >> Games in your vast collection: 4

I recently run into problems converting a ruby script to .EXE because I had a File.write statement in it. The documentation doesn't mention the write method but when I do a
pp File.methods
it is there. So should I use File.write? In a normal Ruby script the following works
File.write("test.txt", "test")
But is it good practice and why doesn't the documentation mention it?
File.write is in fact IO.write (File is a child of IO) which can be verified by monkey-patching:
class IO
def IO.write
puts "IO's class method write was called."
end
end
File.write # outputs "IO's class method write was called."
It is very well in the documentation.
Thus, I see no reason not to use it.
