As a university student, we have to solve some problems and class activity using a Windows app called Minitab, while I don't use any other operating system except Linux.
I installed GNU Octave and statistics package, but when I searched for any tutorial or manual I failed to find out how to plot charts like P chart, Z-MR chart, XBar-S, etc. with GNU Octave. I want to know if it's possible to accomplish the same tasks with GNU Octave for statistical analysis and plotting charts?

Earlier I had tried to install VMware but my laptop does not support required technology and every attempt to get around it failed!
I tried to remove virtualbox with methods described here and this is the result:

I find that LibreOffice is really not user-friendly for writers using right-to-left languages. I'm used to MS Office.
Which word processor can I use in Ubuntu that handles right-to-left languages well?
Trying to change the orientation of just one page in LibreOffice I found this help site of libreOffice to Change the page orientation only for some pages but the what it says to taking care of "The Scope of Page Styles" which is at the bottom of help page was not there.
While following How to install Android Studio on Ubuntu? and Complete Installation Guide for Android SDK / ADT Bundle on Ubuntu to install Android-studio as a solution for Android emulator independent of Virtual Box/VM-ware capability there is a proble that the file we download from Developer.Android.com as sdk-tools-linux-3859397.zip does not contain the add-ons and platforms and I can find just the tools folder .
Below image is from Complete Installation Guide for Android SDK / ADT Bundle on Ubuntu that shows the files used to be in downloading folder.
So when I try to run Android studio I get this message that No Android SDK is found.
In next step installing/updating components, it says that Android SDK is installed.
Next step says that Android SDK is up to date but SDK tools directory is missing.
And nothing works properly. ! Please specify a Android SDK Location.
Trying SDK location for android studio on ubuntu 14.10's solution, I couldn't find any "SDK Readme.txt"
While searching for an Android emulator I found "Genymotion" or "AndroVM" which I can't use because my Laptop is not capable of running virtual machines.
I need an emulator independent of VM's like Virtual Box, prefer options like GPS or Android device configurations.
The first time I installed the hearthstone with the file downloaded from blizzard via "Installing a non-listed program". In that time luncher was loaded and the only problem was starting hearthstone it stuck at a black screen.
The second time I tried to download on the list of POL. First time I got errors but second time after I got error and Battle.net Luncher did not install and crashed. I just copied the Blizzard app folder from the old download and replaced it.
Battle.net Luncher is running and I can login and when I click play and Hearthstone starts just a Black screen appears and that's all I get !

I can't install wininet while winetricks wininet command or PlayonLinux Configuration > Install Components > wininet does not work because they both link to download from MS servers and this file is deleted from their servers.
Q: while I can login and even the Luncher loads its news that means I have no problem of connecting to servers, is it necessary to install wininet ? (while it only interacts with HTTP protocols to connect to Internet)
Q: According to this Workaround For Black / Distorted Battle.net UI On Linux (Wine) With Intel Graphics while I could not update my Intel graphic driver, even I tried to install Intel Graphics Update Tool for Linux* OS v2.0.2 but I couldn't install it.

How can I set the maximum number of active downloads in Uget. As default it's 3 downloads.
I searched but the only related thing I found was this:
Active Downloads Limit Control: specify how many downloads each category is allowed to run simultaneously.
