• Watch syntax help

  - by Jason

  In my Systems Programming class, there are weekly programming experiments, and I'm having trouble with the current one. The objective is to write a C program that slowly writes a string of text to a file, metered by usleep() in a 100 count for loop. The goal of the experiment is to observe the file size buffer in action via the watch command. However, I can't get it to work using watch -d ./output What syntax do I need for the watch command to see the changes made to the file size?

• USB 3.0 controller is not recognized

  - by BlueWanderer

  I have a Thinkpad E430 notebook, and the intel's USB 3.0 controller can not be recognized by Ubuntu 12.04. The LED on my USB-HDD is white instead of blue (And in Windows 7, it is blue when connected to USB 3.0 port, and is white when connected to 2.0). And the transfer speed is around 25MB/s instead of 65MB/s in Windows 7. I'm not familiar with Linux systems, so I've no clue about what's going wrong. I've searched the web, but got no solution.

• Ubuntu in USB.. Boot from fixed HDD?

  - by Z9iT

  I am having Ubuntu 12.04 minimal installed on my USB pen-drive; which I use on several systems as portable OS. I was thinking to edit the boot parameters so that before the main Ubuntu OS is loaded, it shows an option to Boot from Hard Drive for 5 seconds, and then boots to Ubuntu. This way i'll be able to have an option to boot to the OS installed on the Hard-Drive, without removing or unplugging my ubuntu USB stick. How do I edit the boot parameters to achieve this?

Now how can I revert my computer back to it's state before installation.

• C++ Without Source Files

  - by Snowman

  Bjarne Stroustrup mentions in his book "The C++ Programming Language, 4th Edition" that not all C++ implementations use files to store and compile code: There are systems that do not store, compile, and present C++ programs to the programmer as sets of files. (Chapter 15, page 419) Later in the chapter, he reiterates that certain implementations do not use files but he does not give any examples. How would such an environment function compared to a more common file-based environment?
