  • Can't boot from Ubuntu 12.04 live USB

    - by 8vius
    I'm trying to recover GRUB after installing Windows 7. I installed Ubuntu 12.04 first, then installed Windows 7 so I lost the GRUB at startup. Made a USB stick with Ubuntu to boot from, I get the menu tell it to start and it takes off but then gets stuck. The last line showing on the screen is: ata10: PATA max UDMA/100 cmd 0xc800 ctl 0xc480 irq 17 or this: [4.793048] scsi9 : pata_jmicron Then it just gets stuck there and the screen flashes from time to time.

  • No upgrade option when booting from USB (12.04)

    - by Ramzi Njeim
    I am trying to upgrade my ubuntu 11.10, i know that it is better to upgrade using a live cd/usb, i booted from the live usb, followed the instructions as usual, but only found three options: Cleen install Install alongside your other operating systems Other The upgrade choice was missing. I even tried installing it after running ubuntu 12.04 from usb, and ended up with the same result. I have a dual boot Ubuntu 11.10 and Windows 7, i think it is only seeing the windows 7 and missing the ubuntu 11.10 partition. Any help ?

  • What's so useful about closures (in JS)?

    - by Mark Bubel
    In my quest to understand closures in the context of JS, I find myself asking why do you even need to use closures? What's so great about having an inner function be able to access the parent function's variables even after the parent function returns? I'm not even sure I asked that question correctly because I don't understand how to use them. Can someone give a real world example in JS where a closure is more beneficial vs. the alternative, whatever that may be?

  • Should I be running VM's(Virtual Box) for development on the same hdd as my os or a external usb (2.0) HDD or usb (2.0) flash drive

    - by J. Brown
    I have a mac book pro (7200 rpm / 8GB ram) and I like the idea of virtualized development environments as I like to experiment with different technologies and don't like to have environmental cross contamination. I would like to know for the vm's I run (rarely 2 at time..almost always 1 vm at a time) should the virtual hdd be on my laptops native hdd or some external form (usb hdd, usb flash, or since i have mac express card based sad ?). I don't mind maxing out my ram to 16GB if thats a better option to have in the mix. Thank you
