I'm trying to make a DNS in Ubuntu and sometimes I have to use the dig command(I'm using test=system("dig www.google.com")
How can I get the IPv4 from the return of the dig command to them be able to use it?
Do you mean "make a DNS lookup"? If so, try the functions gethostbyname and gethostbyaddr. This is much more efficient than dig.
Or do you specifically want the output of dig? If so, use popen().

I have downloaded a .nsi file and now I have to launch this to get my missing Windows registry keys installed. I tried different things to open it but so far everything didnt work. Can anyone please tell me how to run this kind of files?
A .nsi file is an input to the process that creates an executable. You need the Nullsoft Scriptable Install System compiler: https://nsis.sourceforge.io/Download

Could someone please tell me how to fix it?
The problem would appear to be <Java Home>.
echoing this would attempt to read from a file named Java.
In all probability, you need to change it to %java home%

I would like to password protect my .txt file that has account names and passwords for my program. I know how to encrypt, but I want it to ask every time for a password. By the way, I am using windows. I preferably would not like to download a program however if it is the only option that is fine.
Found this:
https://www.axcrypt.net/
Think that should do the trick.
If you don't mind using Python https://cryptography.io/ is also an option.

When the Kernel needs to send output to a certain peripheral, how does it know which driver to use?
The usual way is for each driver when first loaded, typically at boot time, to poll the buses it supports and look for matches between what it is designed to support and the returned signatures (vendor and device IDs), and their classes.
This is at least the way it works for the so-called plug and play peripherals.

Im having problems with the installation.
I tried this already , http://archlinuxarm.org/platforms/armv7/ti/pandaboard i don't know if im doing it correctly because when i connect it to the HDMI and the tv, nothing seems to work.
I recently got the same problem with my pandaboard ES. I can't say I have everything working now, but you can have a feedback of the boot with the DB9-RS232 port. You'll probably need to use an adaptator DB9/USB to open a serial connection at 115200 baud with the card (you can use the screen program to do so).
