Making a PEM File for iOS Push Notifications (From Ray Wenderlich's tutorial)
# Convert the .cer file into a .pem file:
$ openssl x509 -in aps_development.cer -inform der -out PushChatCert.pem
# Convert the private key’s .p12 file into a .pem file:
$ openssl pkcs12 -nocerts -in PushChatKey.p12 -out PushChatKey.pem
# Finally, combine the certificate and key into a single .pem file
$ cat PushChatCert.pem PushChatKey.pem > ck.pem
# At this point it’s a good idea to test whether the certificate works.

Thorsson / facebook_throttle.rb
Created October 13, 2015 13:48 — forked from pboling/facebook_throttle.rb
Facebook API Rate Limit Throttler using Sidekiq, does not execute the job inside the lock, to maintain some semblance of performance, just marks it in a counter, which other jobs from the same queue and using the same token will also update, and which will be throttled. Jobs from other queues will not be able to bust the lock until the timer run…
# Mixin to (i.e. include in) any worker class that does FB API calls and should be throttled.
module FacebookThrottle
def perform_throttled(*args, &block)
options = args.extract_options!
user = User.find_by_fb_uid(options[:fb_uid])
if user
if !user.valid_facebook_token? # A bitwise flag managed by flag_shih_tzu gem
puts "Skipping #{self.class} #{user.fb_uid}: Invalid Oauth Token for #{user}"
return false
