Nice. If you're ever flying to/from Geneva then book on a tour of CERN. It's right next to the airport and it's free. It was great, highly recommended. Although you don't get to go down to the cavern while it's in operation due to safety reasons (high levels of radiation I believe).

You can sometimes still go down just not past the radiation doors. https://goo.gl/photos/QwiF4EY8XuBBp8zm9 .

Some pics of one of my visits a few years ago in a snow storm: https://goo.gl/photos/926QKx3SgTxbR1vBA

And here a picture from inside ATLAS that I took at another visit: https://goo.gl/photos/Vp99nwLDqrovKfQM7

Either way the visit is well worth it.

Excellent. Thanks for sharing the photos.

Thanks for this. I had no idea this was possible. Changing my holiday plans as we speak.

If you happen to do that before the end of November, please send me an email (it should be in my profile): I'd love to talk to you over coffee!

Can't see it in there. No plans to visit again yet but if you can arrange an underground tour then I may be tempted! :)

That's awesome! Passing by Geneva in August and would have never thought about that.

I wonder if any of the C++ code I wrote in 2003-4 is still used.

Please tell me more.

C++ tool to validate physics algorithms for multi-core stability on researchers workstations, instead of testing them directly on the ATLAS DAQ cluster thus bring it down on errors.

Given my experience with academic coding (and in fact, some fleeting experience with cms stuff) I wouldn't be surprised if it was.
