IMHO, don't put ads on your website until you build some traffic, something like > 500 pageviews/day. You will make a few cents per month until you have consistent traffic and there is no point in annoying your users with ads. Most important thing is to put good content on your website. Blogging consistently, as in 2 - 3 articles per month, is another good tip. Promote your articles on HN and Reddit, but don't spam these every day, just when you think you have something good to share. To give you an example, for a technical blog with an average of about 2500 pageviews per day you get around $50/month from AdSense. AFAIK, for technical blogs you can potentially get more money from affiliate links, like Amazon.
