I was wondering why this code only returns me the same value ten times instead of valuate the conta+0.1 value code...
View 6 Replies View RelatedI am a new user for ubuntu, recently i have updated to 11.04 version last week. When i kept my desktop idle for long time, the system goes down and it didn't wake up at all. I didnt change in the setting for screen saver and power management still. It is system default.
I didnt face this problem when i use version 10. Only the new version i am facing this.
Any solution for this?
I was updating grub and for some reason the system hanged. Going to a tty did not solve any problems. At the end I had to do a hard reboot and came up with the following on the grub boot
reloc offset is out of segment Entering rescue mode grub rescue >
Googling for the above I landed on this page.

While I'm going to try the later part, is there anything else I need to know about ?
Didn't have to do much, took the the Squeeze 6.10.a DVD, asked it to run into rescue mode and then did grub-install giving the MBR (hd0) as the place to be. Things worked nice after that.
Upon booting had to run
dpkg --configure -a
and it updated grub to 1.99-5 among other updates. Did not know that Squeeze had a rescue method as well (just like Ubuntu live CDs have). Now just have to wait for Debian to get Live CD/DVD as default
I'm investigating how to copy a file located in my file system into another device. I googled to find a solution for my case but I didn't find anything. My original problem was to find a way to permit my code to move a file into a USB device. I wonder If is there a way to implement the cp command or some mechanism that permits my code to interact with between the file system on my computer and the second one on USB external driver (FAT32) ?

I am unable to run a certain C code which uses the obsolete compilation method 'imake'. I would kindly like to ask if there is any way that I can run this code. Am I required to install anything? Or do I have to change the code in some way so that it could run on a more updated compilation method?

View 1 Replies View RelatedIn short our required is that we are creating a share library which can be loaded by a process and that share library analysis the process which load it. Since share library is in address space of the process so I need to find out how many threads created by the process and what is status of their stack trace etc.
So I am looking for a way to get list of threads in running process.
how to list the currently running processes via code a shell script. FYI i now about the top method in the terminal but i need a way to have it via a shell script.

I bought a new SD card which I intend to put some MP3s on - except that I can't write to it because it tells me the destination is Read Only. No-probs thinks I: I'll just reformat it.
"Error creating file system: helper exited with exit code 1: cannot open /dev/mmcblk0p1: Read-only file system"
Various chmod commands all result in Read-only file system. I tried umount then mount commands, but it couldn't find it to mount once I'd unmounted it using the same /media/ file path (I assume it's the only one).
My root Vixie cron crontab is set to perform a system snapshot via fsarchiver: 0 0 * * * fsarchiver savefs -o -A /backups/p30_root.fsa /dev/sda2 /dev/sda3 The command itself works fine, generating about a 7G snapshot of my Suse server. I then wish to rsync this to a NAS I have located in another building: 0 3 * * * rsync -av -e ssh --delete /backups/ root{at address}:/DataVolume/os_backups/
(yes, I'm rsyncing as root. I absolutely loathe it, but I got thrown into an quasi-SA position with a ridiculous to-do list and no time to do it. I'm having to make things just work and then go back and try to improve them/learn how. I couldn't make it work in a non-root way quick enough, so for now I'm having to cron rsync jobs as root because of all the differing file permissions on this samba/MySql server. I set the NAS to only accepts ssh from the server IP, and we're behind a campus firewall... It's serious trial by fire.) The crontab also has rsync commands for the samba areas, our specialized chemistry software and affiliated MySQL databases............
I am working on a project with a lot of vector math and I'd like to find a way to speed it up.eading about SSE, but I've found no explanation on how to actually use it in code (was looking for some kind of hello-world example, complete with compilation instructions).Does the gcc compiler automatically make use of SSE, if you add the -sse(2,3) option on the command line? Or are their specific functions/libraries you need to call?
View 12 Replies View RelatedMy system decided to crash on me, hard. It was humming along happily for about 2 months and now doesn't boot. If I boot from hard-disk, I get grub. Launching the first kernel choice hangs. I thought maybe the install was corrupt, so I booted from usb install disk. The usb hdd didn't boot; something about an error trying to access /dev/sda . Unplugging the internal disk and plugging in the usb install disk does result in the system booting. Plugging in the internal disk in a running system usb-booted system does not result in the system detecting the disk.
How do I know if the disk is physically broken? This seems unlikely since it does manage to launch grub consistently. Or is this still possible? How can I try to mount whatever is left? The usb install disk doesn't even list the /dev/sd*. Any pointers on how to reformat the drive if it's not being mounted?
I installed a slack 13.7 on an old laptop. KDE was set as default desktop. then I login and run startx and I saw KDE first screen display. after that I saw blank screen with a mouse on it. Then it stayed there and it seems try read some in my harddisk since the persistent harddisk light.

Is there, by chance, a fancy name to describe code that must be in a program but will never be executed? In one of my (Haskell) programs, I have some error-handling code that must be in the program to keep the compiler happy (due to the type checking). However I know that, due to the logical structure of the program, it is impossible for the code to be evaluated. I am curious if there is a technical name given to code that must exist but cannot be executed.

I am an absolutely beginner with Linux (ubuntu). I got fed up with widows and decided it was time to go. I installed (clean install from a cd) ubuntu 10.04 on my desktop. It is an hp compaq d220 MT.It looks good and feels good, well at least for a while since it keeps crashing. The screen starts to flicker, goes black, and the only way to get it up and running again is to press the on/off button until the system powers off and restart.

But i wanna try 64bit Linux(probably slackware) on it. But first im just wondering what the advantages are people have seen who have used both 32/64bit linux. Speed? Smoothness? And also what are major disadvantages such as compatibility, configuration, etc.
