Sorry, RSA, I'm just not buying it

I want to be extremely clear about three things. First, this is my personal opinion – insert full standard disclaimer. Second, this is not a condemnation of everyone at RSA, present and past. I assume most of them are pretty okay, and that the problem is confined to a few specific points in the company. However, “unknown problem people making major decisions at RSA” is a bit unwieldy, so I will just say RSA. Third, I'm not calling for a total boycott on RSA. I work almost literally across the street from them and I don’t want to get beat up by roving gangs of cryptographers at the local Chipotle.

RSA's denial published last night is utter codswallop that denies pretty much everything in the world except the actual allegations put forth by Reuters and hinted at for months by [other sources](http://li

A not politically correct assertion of my feelings towards a piece of software:

Note: Repetition builds cynicism, asset_sync isn't bad, but when an asset problem cannot be solved via support it gets escalated to me. Often times someone using asset_sync the problem is due to their use of the library and not from Heroku.

Backstory

The asset sync gem uploads your assets (images, css, javascript) to S3. From there you can either point browsers to the copy on S3 or use a CDN + the S3 bucket. It's a good idea, and solved a problem at one time.

It is no longer needed and you should now use https://devcenter.heroku.com/articles/using-amazon-cloudfront-cdn instead. So rather than copying your assets over to S3 after they are precompiled the CDN grabs them from your website instead. Here's some reasons why it's better.

How to setup your own CA with OpenSSL

First things first

Lets get some context first.
