1)  How does the person spend his or her free time?  Per Ayn Rand's observation above, what does he or she do for enjoyment?  

2)  How does the person respond to your successes?  Many people are willing to commiserate with you when you're down and elevate themselves in the process.  A person of genuine goodwill celebrates your successes and is happy for your happiness.

3)  What strong beliefs does the person voice and live through their actions?  Character means standing for what you believe in and living your beliefs.  Go along and get along might be comfortable, but commitment is what powers effective action in the world.[..]hree-powerful-measures-of-character.html

Why merge often -[..]/cgi-bin/cmwiki/view/CM/BranchYesMergeNo

A lot of resource here -[..]i-bin/cmwiki/view/CM/BranchingAndMerging

At my company, we tag each CVS module and we use those tags to build releases. That way, we know exactly which code versions each deployment has. Also, developers can check in code at any point while controlling when they release it.

Branches are a major headache, which I avoid whenever possible. You have to worry about maintaining and testing each branch, along with merging changes. I prefer to release the latest and greatest code to each customer. If different customers require different behavior, if statements and configuration files are a lot better than CVS branches.

Branches do make sense if you want to release a minor change to an old release, but upgrading the entire code base is risky. However, high-quality code and testing should reduce that risk.[..]arent=16312&ixDiscussGroup=3&cReplies=11

Another discussion -

Branch visualization -[..]07/05/linus-torvalds-on-git-and-scm.html

One way of manage branching and merging, the summary is, frequency create new branch for pre-merge instead of one time big merge -[..]old-you-about-svn-branching-and-merging/ My colleagues suggest subversion merge tracking can solve the problem without that pre-merge, but I am not sure how that can work...

Law #5: Weak passwords trump strong security
Law #6: A computer is only as secure as the administrator is trustworthy
Law #7: Encrypted data is only as secure as the decryption key
