Developer Event: Learn Ethereum with Vitalik!

Details
Note: as usual please add yourself to our skype channel for London Developers by adding 'stephan.tual' and specifying 'London Workshop' in your request, thank you!
Very special event today, with Vitalik Buterin leading the workshop and covering both the python client AND the serpent language! RSVP early to avoid disappointment!
Do you like the bleeding edge? Not afraid of compiling things on Linux or OSX?
Then please RSVP to register your interest in attending this developer-specific event, focused on learning how to program smart contracts in Serpent ( https://github.com/ethereum/wiki/wiki/Serpent ).
This event will be provided free of charge. Attendance is limited to 30. Unfortunately until we find a sponsor we won't be able to provide refreshments and food, but a cafe is available in the same building with vegatarian options if required.
We expect it to last a whole day, with 1/2 dedicated to learn everything about Ethereum, smart contracts and their decentralized GUIs, followed by a mini hackathon until max 7pm.
Level of skills required is fairly high as Ethereum is currently rapidly iterating over its software, so things will break. Please try and insure you have the client installed on your platform before arriving especially if you run linux
Installing on OSX:

Installing on Linux:
https://github.com/ethereum/cpp-ethereum/wiki/Building-on-Ubuntu
Installing on Windows (not recommended, use a VM instead)
https://github.com/ethereum/cpp-ethereum/wiki/Building-on-Windows
Ideal background would be 2+ years of web development, although anyone who can program in Python, C++ or Java should feel relatively at home, too.
We reserve the right to refuse entry and will validate the guest list to make sure everyone has a good time with peers of the same skill level.
HOW TO GET THERE
Once again, the venue and date is secured thanks to the amazing people at the The Escalator ( http://www.theescalator.com/ ). Their twitter handle is @LondonEscalator (https://twitter.com/LondonEscalator)
Once you are at the address (you can't miss it, it's a huge building!), enter the Cafe Foxcroft and Ginger (to the left of the big dog mural) and directly make your way upstairs. There will be Ethereum signs, but not necessarily staff to welcome you as it's a Sunday, so tap on the door if needed and ask security to let you wait in the reception area.
If you are late, make your way directly to the "Coin" room (against please ask security to show you the way).
