And answer the questions in the following way:

  • Enter (Continue)
  • 4 (Linux)
  • Enter (start with every system start via /etc/inittab)
  • 1 (USB device)

Unfortunately, the driver needs an older version of a library which is not being shipped with Ubuntu 11.10 anymore (/usr/lib/libXm.so.3):

$ sudo /etc/3DxWare/daemon/3dxsrv -d usb
/etc/3DxWare/daemon/3dxsrv: error while loading shared libraries: libXm.so.3: cannot open shared object file: No such file or directory

iRoot is a product of the India-based Neutrino Observatory collaboration lead by Prof.Naba Mondal at the Tata Institute of Fundamental Research.
It is a simple plotting and analysis tool based on the popular ROOT from CERN and is primarily intended for analysis using the TTree structures in ROOT. iRoot is supported by a user-friendly GUI designed using Qt.
If your data is stored in TTree stuctures and you want to perform simple analysis with your data without writing any piece of code, iRoot is for you. It has GUI interfaces for most of the jobs that one is most likely to perform with TTree data. Fitting, analysis with PROOF, converting TTree data to ASCII, uploading plots to the cloud etc., are some attractive features to mention.

Linux

neighbour discovery:

# trigger the discovery
ping6 -c2 -I eth0 ff02::1
# print the results:
ip -6 neigh

Or with the network interface specified in a shell variable and the commands put in a single command line:

IFACE=eth0
ping6 -c2 -I $IFACE ff02::1 && echo -e "\nIPv6 Neighbours:\n" && ip -6 neigh

Mac OS X

Neighbour discovery (command for IPv4 was arp -a -n):

ndp -a -n  # the -n prevents ndp from reverse looking up the IPs

Windows

Most of the standard network utilities of Windows will also work for IPv6 related matters. Standard utiilties are:

If you have an SQLite database file and want to check its structure (programmatically)

SELECT * FROM sqlite_master;

To do this via Python as simple as possible, run:

conn = sqlite3.connect("your/database.sqlite")
c = conn.cursor()
c.execute('SELECT * FROM sqlite_master;')
for row in self.cursor:
    print row
