Pretty good indeed, thanks to all!
I'm going to provide in the chapter coords' shared doc the inputs for the connection to the demo, let's hope nobody objects for using hangouts...

Hi,

Davide and me have done the test for monday's demo, here you have the results:

  *   The web page for the demo is hosted in http://130.206.127.115/demo1/
  *   In the first test, turtlesim started but firos didn't. We have been checking, and the last time firos seems not to be closed correctly, Davide has check if RCM sends the correct signal to firos (SIGINT or SIGTERM) and it seems that is ok, it sends SIGINT. Davide has closed it manually.
  *   After that, we have send to RCM start signal, moved the turtlesim and send stop signal to RCM for 3-4 times and it has worked perfectly every time, so we think that the environment is ready for the demo.

For the demo we think that the computer that contains the turtlesim (the one that yesterday I access via VNC) should be started from scratch, to avoid the possibility of having firos port busy again.

For next releases we are going to take in mind what has happened today to try to solve it.

Regards,
Iñigo

Hi All,

I'm pretty sure you don't need me to be present for the tests, but just to let you know I'm not available this morning.

Hi Davide,

as Angel said, we have thought about a fast workaround without any visual feedback for the user. We have already added it to the page, so if you want we can have a hangout at 10:00 or 10:30 (if you prefer another our tell me please), to test everything.

Is it all right for you?

Regards,
Iñigo
