Wow. People on HN do a lot of cool things but that really blew me away. It all sounded so casual too.

This is real Hacker News.

The thing I love most about her work is it's witty, but to the point and I can always understand it.

I'm not a big fan of the tl;dr movement, but I also don't like dauntingly long blog posts. Nails it every time. Hats off!

You can basically reverse those terms for me. I'm a mech engineer who wished he knew more/was better at the web-dev / big data stuff.

Sounds like you guys should be friends.

Sounds like if they ever met, big explosion !

You've probably already seen it, but in case you haven't: her talk at 30C3 was excellent and is worth a watch. https://www.youtube.com/watch?v=R-2k6TMPMRo

Been there, was cool indeed! If you aren't planning to already, you should come to the 31c3 :)

It is a certain commitment to Germany over Christmas.

can this become/or is/ part of forensic science? if its possible to do the same on a mobile phone, and merely speaking into the phone, you give away your travel trajectory?

They're way ahead of you :- They can take any audio recording (from any source) in the UK and get an exact time-stamp of its recording and detect whether it has been edited in any way : http://www.bbc.co.uk/news/science-environment-20629671

Amazing!!! I would have just dismissed it as static interference, and not even think twice. Hmmm, makes me think twice about the beeping sounds I hear when my phone is right next to my radio. I know it's data being transmitted/received, but I wonder if it can be deciphered in this manner.

She already did that :)

I didn't get how she can get so much sense out of what is basically line noise - until the comment that asked what tools she uses, and she says Perl. Ah, just a day in the life :)

Suddenly, my telecom courses in CS now seem a lot more fun than they really were. It's like magic.

While I love the blog and the very clear explanations, none of this is new nor amazing to the experienced RF engineer, enthusiast, or practitioner. What's awesome is that the hardware and software are currently cheap enough that more people can discover and enjoy the larger spectrum around them. Welcome!

Now go build some antennas! :)
