Related to this, if you run a mail server consider looking into DKIM. It is an interesting addition to the Internet mail architecture and not that hard to enable via a sendmail milter (OpenDKIM).
Masada
On my last trip to Israel I finally made it to Masada. We hiked the ~1000ft up the mountain and while we were on the top fighter jets patrolling the border flew below us. Recommended if you get the chance.
tcviz
Anyone making use of Linux’s traffic management tools should take a look at tcviz. It generates a graph of the configured queues, classes and classifiers. Below is an example from one of my scripts.
Version control in government
I’ve often wondered if version control would be a useful addition to democracy. Imagine being able to get a diff which showed which parliamentarian proposed a particular amendment to a bill or see the entire change history once a bill became law (the later is like a software release).
In the open source software world many people are driven to do excellent work at least in part because there is a public record for the world to see. Perhaps this same transparency and historical record would drive deeper thought and less willingness to propose bills and amendments on behalf of other people and organizations.
With a slightly different angle, Clay Shirky discusses the idea of version control as a tool for government in his recent TED talk. He even provides a basic background on version control which might be useful if if this whole post makes no sense to you.
