May 16, 2010Sometimes while using Open Office, trying to open a file the dialog box takes 15 to 30 seconds of spinning balls until it shows me anything. Then changing a directory takes another 15 to 30 seconds. Visual feedback on selections take several seconds, and often I find myself a couple of subdirectories down from where I wanted to go due to caching of unacknowledged clicks.
My system is usually very, very fast, as one would expect from the specs. This problem happened, well, almost all the time with kernel 2.6.32-21-generic, now it just started happening again with 2.6.32-22-generic.During these slowdowns, opening Dolphin reveals the same problem, exceedingly slow response. While this is happening, top shows the system is not busy, and the hard disk light is not flashing. Idle is over 90% and user and sys are basically nothing. The system is basically doing nothing while making me wait.
Ubuntu :: File Operations Is Buggy?
Sep 3, 2010Whenever I move files from a USB memory stick or external hard drive or any other such device the file only seems to transfer 99% of the data and often during moving file operations will freeze and an offer of 'force quit' will come up (although file operations will eventually vanish with the 99% of the file being moved).
Can anything be done to rectify problems with file operations?

Jan 20, 2011We all know linux kernel base layer is made up of structures, in which every object of kernel is well defined. Structure members correspond to object properties required to define object behavior.
For example if we take case of File system.It composed of four objects , superblock objects, inode objects, file objects and dentry object.Each having well defined structure which is being operated by system call handler and by system call service routine in the kernel mode.
Now my question is even in kernel mode we do not have some mechanism by which we can get access to pointer of these structures.We have some macro.
If I want to manipulate structure on my on way, or performing some more operation defined by me.For example after the crash of Hard Disk Drive, having ext2/3 file system, If i want to know all the inode pointers, and block details.
Can I have some way out to do desired operation ??
mechanism to operate on these base label structures, even in kernel mode ..

Programming :: Make A Folder For Each File In A Directory Then Move The File Into It
Nov 29, 2010Initially I thought - use a for loop with ls in it:
Code:
However this causes lots of problems (folders have extensions, I have duplicate folders, the names with spaces create a folder for each element of the name).
The contents of the folder is basically movies (some with subtitles). Some of the names have things like (original) or CD1 CD2 in them.
Ubuntu :: Large File Copy Operations Freezing Up Computer?
Sep 9, 2010Ok so I'm running Mint (not full Ubuntu), and I'm not sure if this is a problem with the FS, Kernel, what not.I'm running Linux Mint 9 - x64 - kernel 2.6.35.14 - and when I did a large file copy operation (9GB) it froze up my system until the copy operation was done. I couldn't even use Pidgin, Mozilla, or anything, when trying to open up another Terminal it froze as well.

Ubuntu :: Laptop Freezing On Extended Operations Involving The File System / Hard Drive
Oct 4, 2010I have a Toshiba laptop that seems to be freezing on extended operations involving the file system/hard drive. (that's kind of a guess on my part). The system has frozen during the last day or two when I:
- try a large file operation with Nautilus
- try exporting a large video file from Kdenlive
- try formatting the disk for a new install of Maverick (I decided that with the new version almost out, I might try upgrading in case I broke my system)
What I see is the screen freezing and the mouse does not move. As I said, I tried installing the Maverick RC from the Alternate CD (I wanted to do a minimal install). The install hung on the partitioning step and the caps-lock key started blinking (though I don't get this in other cases). I have booted into my Lucid live-cd and a Puppy live-cd to try Gparted, with the same results - the system freezes (but the caps-lock key doesn't blink). Puppy HAS performed better generally, for example I was able to complete my large file operation (backing things up!) but it is freezing on the partitioning step.
Debian Programming :: No Such File Or Directory
Sep 18, 2015I’m new to C programming so I wrote the following program to see if everything I needed to write programs with GCC and the standard C library was already installed. I am having issues in OS 10.10.5, where I am unable to build and compile some simple code, either using Xcode or Sublime text. I decided to install Linux Mint in Virtual Box to see if it would work.
Code: Select all#include <stdio.h>

}
For some reason, I'm getting the following error:
