On Ubuntu 12.04 LTS, I installed VirtualBox (last version) where I am running Ubuntu 12.04 LTS and Ubuntu 14.04 LTS.
I noticed a significant difference in terms of performance: mainly, the speed. All the tasks I run on Ubuntu 12.04 are faster. I want to do most of my daily work on Ubuntu 14.04 but every task seem slower. I tried them on Vmware Player but the difference is still the same.
I just got a new ThinkPad X230, 4 Gigs RAM, core i5 processor (3210m), and Windows 8.
I wish to dual boot it with ubuntu 12.04.1 64 bit. I got the release page but it's got several links for downloading ubuntu, also the links are a bit confusing. What is MAC-amd64 for? And what's the difference between desktop and alternate download?
The release page: http://releases.ubuntu.com/precise/
It seems that Ask Ubuntu and Questions for Ubuntu on Launchpad at https://answers.launchpad.net/ubuntu cater to the same type of questions. What is the difference between the two, in the sense that in which of the two should I post my questions? Is there any duplication of effort?
When I try to download Ubuntu Desktop and try to save, it shows different URLs. What is the difference between these different URLs. Which is the safest one? ( eg. releases.ubuntu.com ; ubuntu.excellmedia.net etc. ) Can I download it from anywhere? Need I care for these things? What should I care just before saving the file.
What's the main difference between programming the Windows and in Ubuntu? In university, is it necessary to program in Ubuntu? I currently have windows and was thinking of switching but I would need to dl everything again ;;
I want to use some devices on a Ubuntu VM in VMWare environment. I have a choice of using them as RDM or VMDK. I was originally thinking of using them as RDM due to performance benefits. However I am running into some issues due to compatibility (somewhere in the software-hardware stack of ubuntu version, ubuntu kernel version, driver, motherboard, disks etc.).
I just wanna understand the difference between ubuntu and all these other OSes (distros?). I've seen the word "distro" loosely used around the internet and I'm assuming it's the shortened version of "distribution", but wouldn't Ubuntu be a distro as well? Or do I have it confused? Can someone shed some light on this for me please?
