Playing with Apache...

If you are playing with Apache on Windows and you keep getting

E:\IBM\HTTPServer\bin>apache.exe -k start
[Fri Jan 31 00:12:00 2014] [notice] Disabled use of AcceptEx() WinSock2 API
(OS 10048)Only one usage of each socket address (protocol/network address/port)
is normally permitted. : make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

Before getting mad and reviewing all your httpd.conf line by line, try to quit Skype. Yes, by default it opens port 80 !!!

When adding a property to graph-tool don't forget this

When you are adding a new property to a graph-tool graph (https://graph-tool.skewed.de/) is_node_customer = network.new_vertex_property("bool") weight = network.new_edge_property("float") you should never forget to add this network.vertex_properties["is_node_customer"] = is_node_customer network.edge_properties["weight"] = weight Otherwise the properties will not saved or stored together with the graph and you will lose a lot of time
