Eden Harder's questions

The device I want to mount is Nokia 130. lsusb or lsblk cannot find it, but dmesg will, some part of the output is following:

How can I mount it?

I tried to follow the examples at Quantum Circuit Plotting with SymPy but I could not find the output picture.

My OS is Ubuntu and I typed all the commands in the terminal of IPython, as you can see here:

The output is similar to the one in that website,

<sympy.physics.quantum.circuitplot.CircuitPlot object at 0x7fa125ee5c10>

So, where is the output figure? In some folder?

PS: I run again and get another similar but different output

<sympy.physics.quantum.circuitplot.CircuitPlot at 0x7f6ff0903690>

My os is ubuntu 13.10, I use the following code to remove the kde desktop installed before:

  sudo apt-get purge kde*

And then use the following code to install gnome 3.10:

  sudo add-apt-repository ppa:gnome3-team/gnome3-next && sudo apt-get update
  sudo apt-get update && sudo apt-get install gnome-shell ubuntu-gnome-desktop
  sudo add-apt-repository ppa:gnome3-team/gnome3-staging
  sudo add-apt-repository ppa:gnome3-team/gnome3
  sudo apt-get update && sudo apt-get dist-upgrade

After all these were done, I restart my computer and can not find my cursor in Unity while all things are ok in Gnome. I want to find the cursor in Unity, what should I do? Any help or suggestions will be appreciated!

I tried to install Pythonika on my Ubuntu 14.04 (64) with python 2.7.6. I followed Salem's answer, but there are some errors.

I add some new .m file to /usr/local/Wolfram/Mathematica/9.0/AddOns/Packages/ and then call for it in Mathematica, but failed with the message Get::noopen: "Cannot open \!\(\"Qdensity.m\"\).".

What should I do to make it work?

I change the partion of the system with Geparted in the liveusb, ignoring some warning. Then reboot, 'grub>' appears but I can not find the boot or grub folder anymore. Afterward, I reinstall ubuntu and I pay a high price. Then I want to learn a better way rather than reinstall when one comes into this case.

I download the tar.bz file from the home page of zotero, extract it and run the file 'run-zotero.sh', but it open zotero rather than install it. How to install it? Any help or suggestion will be appreciated!
