It is no secret that we at CloudFlare love Go. We use it, and we use it a LOT. There are many things to love about Go, but what I personally find appealing is the ability to write assembly code!...

Some interesting changes related to timekeeping in the upcoming Go 1.3 release inspired us to take a closer look at how Go programs keep time with the help of the Linux kernel. Timekeeping is a complex topic and determining the current time isn’t as simple as it might seem at fir...
