Flights web site

Ubuntu Window Grouping

The default window grouping setting in ubuntu results in opening a separate tab, in the bottom bar, for every application running.
i.e. if you are using skype and you are talking with 3 different users you will see three different tabs in the bar.
In order to change the window grouping settings follow this steps:

1. Right click on the bottom bar, on the left (in the visible space);
2. Preferences
3. Check Always group windows

In Windows there is cache for DNS. In order to refresh the cache from command line and refer to the correct IP you need to execute this command:

After that verify the correct IP of the website you want to connect using:

$ tracert <myWebSite>

Thanks to my colleague Roman.
