This 35-minute video from the recent Google I/O conference explains how to use Go’s concurrency primitives — goroutines, channels, and the
select statement — to do things elegantly, correctly, and safely in a few lines of Go, which would otherwise turn your brain into a pretzel in most programming languages.

I recently had to do some customer work involving the McAfee MySQL Audit Plugin and would like to share my experience in this post.
Auditing user activity in MySQL has traditionally been challenging. Most data can be obtained from the slow or general log, but this involves a lot of data you don’t need too, and isn’t flexible at all. The specific problem of logging failed connection attempts has been discussed on a title="auditing login attempts in mysql" href="http://www.mysqlperformanceblog.com/2012/12/28/auditing-login-attempts-in-mysql/">previous post in our blog.
Wow, talk about an industry that’s overcrowded with look-alike me-too products. Online agile project management tools are a dime a dozen, which makes me think that they are probably all very similar and probably don’t solve most people’s needs. I’ve observed that when this is true, nearly-indistinguishable tools get reinvented, until the burden of evaluating the options is greater than the burden of just building yet another one, thus perpetuating the cycle.
Here are some of the products I looked at yesterday:
