Myself and friends have had great success meeting technical folks and candidates for co-founders at networking events such as Start-up Weekends (http://startupweekend.org/) and local networking events you find through www.meetup.com such as Hackers and founders, Startup Meetup, Minnesota Entrepreneurs (Check within your state). If you are unable to network at events like this there are other avenues such as co-working space (In MN we have - http://cocomsp.com/locations/minneapolis/, Startup Loft - http://www.svl.mn/ etc) Good luck.
Hi! Simplest answer is by networking.
Get out there, as entrepreneur you are already required to step out of your confort zone and one of the reasons is to find others who value and join your ideals as well as possible evangelists.
Find networking groups or co working spaces that will provide you with valuable interactions with those in your area of insteret. There are also a ton of CoFounder matchup websites where you can post your profiles and find a "soul mate"
For a bit more control, create your own MeetUp group for specific interests that will yield a potential cofounder.
Your chances in finding a committed cofounder amongst a list of applicants are very low because of the nature of their job search and your startup abilities to provide job security and great pay (unless you have great funding already) so you are better off looking out for those already interested in startups or have both experience and free time besides loving your idea.
Good luck out there!
I'm not sure there's a simple formula for this one. I've seen in past experiences the most successful co-founder situations result from networking within a small community. If you can meet someone through a friend, your chances of success increase dramatically. If that's not possible, another option is attending MeetUps for specific interests (like software development or specific coding languages). The final suggestion I have although probably most difficult is joining startup weekends, getting on a team with some technical talent, and seeing how well you mesh together throughout a long working weekend.
