OpenSSL command line recipe for multi-public key file encryption. Any single private key paired to one of the public keys can decrypt the file.
#!/usr/bin/env bash
#
# Example of multiple key AES encryption for text files using the openssl v. 0.9.8+ command line utility
# Uses n public certs as key for MIME PKCS envelope, any individual private key can decrypt.
#
# If standard RSA ssh keys exist, these can be converted to public certs as well (and ssh keys can decrypt)
#
# To sign (and verify) the encrypted file, one of the private keys is required, see:
# http://www.openssl.org/docs/apps/smime.html#EXAMPLES for openssl smime examples
# or http://www.openssl.org/docs/apps/cms.html#EXAMPLES for cms utility (OpenSSL v. 1.0+)

15 Questions to Ask During a Ruby Interview

Originally published in June 2008

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.
