Hello Outriders!

This week on the podcast I have an update on tech and online observation in Libya, a new robot to introduce you all to and one of Outrider's founding fathers back with us - Chris Vallance has been finding a little Chaos.

Many of us online have been observing social networks in order to get a handle on what has been dubbed the Arab Spring. Various revolutionary movements have taken place in Tunisia, Egypt, Libya, Syria and Yemen. The last weeks have seen more bloody fighting as rebel forces in Libya stormed Colonel Gadaffi's compound to find that there was no one home.

So how to make sense of these events from a distance and to translate updates in a timely fashion online - especially when you are not a large news organisation?

Well, has been doing just that and he managed to find a moment way from answering the emails of journalists and web watching to tell us more about his role and exactly what he does online.

It's one thing trying to spread a message when you are an activist so that people like John can hear you - but it's also important to ensure that your data is also safe - safe from those who may use it for other reasons or to do others harm.

Luckily there are organisations who can help to keep data safe for people who need it most. Stephanie Hankey is the executive director of , she told me more about what they do and how their new fits into the team.

Old time Outrider, Chris Vallance returns to take a look at phone-hacking and mobile phone security. Phones have changed a lot since concerns were first raised about voicemail security over a decade ago. As mobiles get ever smarter, Chris talks to some leading security researchers about the next generation of threats to the security of our calls and data.

And there ends another edition of Outriders. In the mean time you can email me at Outriders at bbc dot co dot uk, give me a nudge on Twitter at , or search for Outriders on to find our page there.

Until next week!
