Touchpad and WiFi stopped working on Ubuntu

-
The last thing I remember about using this laptop was that bluetooth had stopped working. Even though it worked when I booted up Windows 8. I remember fiddling around with scripts I did not understand. So when I booted up my old laptop weeks later, I found that mouse(touchpad) and WiFi were dead too. What's more, everything worked fine on Windows.

Let's cut to the chase. Since I did not have a working internet connection on the laptop(in Ubuntu), I wondered if I could reinstall the touchpad packages and opened up Synpatic Package Manager, which gave me an error asking me to run the following

> sudo dpkg --configure -a 

I ran it and rebooted Ubuntu. Mouse and Wifi started working after restarting the system.

CS50: "undefined reference to `GetString' " and other errors

I was going through the CS50 lectures of Fall 2011. CS50 recommends using the CS50 Appliance which is a VirtualBox installation of Fedora with libraries and software needed for the CS50 course. However, if you are already running a flavour of Linux (Ubuntu 12.04 in the case of this article) and want to do the examples natively, read on. On Linux, the CS50 manual gives instructions on how to install the CS50 Library for C  for Linux ( Fedora / Ubuntu ). After installing the CS50 Library for C, I tried running some samples. While making pointers.c in the Week 5 lecture, I came across this error $make pointers cc     pointers.c   -o pointers pointers.c: In function ‘main’: pointers.c:27:5: error: ‘for’ loop initial declarations are only allowed in C99 mode pointers.c:27:5: note: use option -std=c99 or -std=gnu99 to compile your code make: *** [pointers] Error 1 If instead of using make, you use gcc pointers .c you will get a similar error. To correct this, I ran $gcc pointers.
