Sylvain_Hellegouarch_AvatarMy name is Sylvain Hellegouarch and I’m a 36 year-old French guy currently living in Rennes, France. This blog is my personal notes on various topics though mostly related to technology like social networking protocols.

I hang out mainly on IRC channels on OFTC where¬†you can find me under the nickname of Lawouach. I’ve written a book on CherryPy but don’t let that fool you, it’s not a cookbook about delicious pies. Aside from that I’ve been playing the guitar for too long to remember and I don’t tire of it. I write open source software and I’m involved in the opening up our public data.

If you like what I contribute to, by all means send me a postcard, buy me a book or some beers and I’ll be more than happy.

Thanks for stopping by and enjoy your stay.

    Dear Sylvain Hellegouarch:
    Thanks for your ws4py.I’m a newbie pythoner, i’m try to using ws4py to make my own application these days,i got a problem: i only know cherrypy.engine.publish(‘websocket-broadcast’, TextMessage()) can send a message to all connected clients, could you get me a sample about how to send a message to one connected client? Tons of thanks.God bless you!

    Hi Sylvain,

    I’ve seen you’ve been working in some python projects, and the one I’m interested in is cherrypy. At the moment I’m trying to create a little web application using cherrypy and ssl. I’ve been reading documentation on Internet, following your examples in bitbucket.org, but with no luck because I can’t make it work. I’ve been reading that there is a problem with using python 64 bits as it can be very painful to set up openSSL and pyOpenSSL.

    Thanks and congratulations for your website.
