<p>I'm planning to give a tech talk at a Golang local meetup but am short of ideas. The talk is in a month and the audience knowledge of Go is at an intermediate level. </p>
<p>The previous talks at the meetup were theoretical. I want to do something that has a healthy mix of both practice and theory. I would appreciate any suggestions.</p>

Mutex is sometimes the right answer. Lock free is cool too.</p></pre>fungussa: <pre><p>I'd think that highscalability.com would also offer inspiration</p></pre>jeffallen: <pre><p>Work through an example of making a not easy to test function into a testable one using interfaces to allow you to mock dependencies.</p>
