Best non-paperclip solution for S3?

There was a question about uploading to S3 on an iOS project backed by non-rails ruby.

Best practice (Rails or not) seems to be using the AWS gem to generate URLS, send those to the phone, and do all the manipulation and uploading from the device.

ciborg and passphrase on key file

If you have a password on the keyfile lobot is using for git, jenkins will fail to checkout

ciborg and id_rsa

ciborg always upload the keyfile as id_rsa even if yours has a different name, it copies the correct file but drops it as id_rsa and has the reference to your correct name in the ciborg.yml.

ActionController::Base#view_context

Easily access view helpers from your controller, without including modules. Use view_context.some_url_helper for example.

Using controller in presenters

Sometimes you need to use the controller / view_context to access methods you could not in the presenter.

When it's the case, don't put them as a parameter of the method that need them.

This is not a value object (remember Domain Driven Design? :), this is a dependency you should inject when creating your presenter.

We need a certain amount of buy-in before we can extract it on client time.

Rspec after's run in reverse order

Not that you should probably ever have multiple after blocks at the same level, but we found out when collapsing multiple after blocks down into a single one, that the teardown happened in the opposite order than the order in which the after's were declared

Not all PNGs are created equal

If you write a UIImage’s PNG representation to disk, read it back, and get the PNG representation again, you’ll get a different representation. In our case, we got 21 extra octets after the PNG header.

NSData *png1 = UIImagePNGRepresentation(image1);

[png1 writeToFile:file atomically:YES];
UIImage *image2 = [UIImage imageWithContentsOfFile:file];

NSData *png2 = UIImagePNGRepresentation(image2);

// png1 and png2 differ by 21 octets

heroku_san + ruby 2.0

If you are using heroku_san with a ruby 2.0.0 app and you get deployment failures and the message is:

"Your Ruby version is 1.9.3, but your Gemfile specified 2.0.0"

You need to edit /usr/local/heroku/bin/heroku
and change the shebang line:

#!/usr/local/heroku/ruby/bin/ruby

to

#!/usr/bin/env ruby

So that the heroku toolbelt runs with the ruby version invoked locally in your rbenv/rvm environment.
