I am having major lag spikes in the game Counter Strike Global Off., does anyone know how to fix the game (IT IS THE GAME NOT MY INTERNET). — Preceding unsigned comment added by 76.16.47.115 ( talk) 02:57, 26 August 2012 (UTC)
Anyone here have this particular model laptop? I need to know if I'm the only one experiencing problems with the touchpad not being sensitive enough so I can know whether to return & exchange it for another one of the same model or get a different one altogether. 70.52.79.25 ( talk) 08:55, 26 August 2012 (UTC)
Hi,
Does anyone know of a quick way to save a MATLAB plot (to png) without actually having to call up a figure? I need to process a large number of frames (1000s) to make up an animation and at the moment I'm creating a figure and then using print(gcf,...) but this is pretty slow... Thanks, -- Fir0002 11:26, 26 August 2012 (UTC)
I need to accept a location from the user, compare it with the current location (using GPS) and give an alarm to the user if it matches. I'm new to android, but I do know that I need to use LocationManager and AlarmServices. Can someone please give me an outline of how to go about it and especially how to integrate alarms into GPS. I'll be most grateful for any help provided. Thank you very much. :) Z ebe c 15:26, 26 August 2012 (UTC)
Dear Wikipedians:
I have just performed a security swipe on my Playbook using its "security swipe" feature under the security section of its settings pages. However, the length of time between when I tapped "security wipe" button and when I got the new splash screen asking me to set up my "new" playbook is such that I do not believe my playbook has had the time to go through all the bytes in its 16 GB of permanent memory and reset each one of them to 0x00. I am wondering if any of you could help enlighten me to the true nature of Playbook's security wipe, whether it really does its job, and what else I can do to make sure all my data on my Playbook is fully erased and could not be recovered, even with forensic computer data retrieval expertise, in case Playbook's in-built security wipe does not do the full job.
Thanks a million,

I read the question as "Playboy's security swipe" and wondered that there's now such a convenient feature available... JIP | Talk 18:16, 26 August 2012 (UTC)
After I had upgraded to Fedora 17, I found that when I first booted it up, everything worked, but when I shut the computer down and booted it up again, Fedora went to emergency mode before I could even log in, asking me for the root password, and when I gave it, dropped me to a text-only shell. In panic that I had broken the system, I reinstalled Fedora 17 and everything worked, but after I rebooted, the same problem appeared again.
I decided to google "Fedora emergency mode" and found the cause of the problem. I have additional Lacie external hard drives that I use for back-up, but I keep them powered down when they're not in use. I have written entries for them in /etc/fstab
so that I can manually mount and unmount them with a single command. Now what was happening was that on boot-up, Fedora found these entries in /etc/fstab
and tried to mount them, but failed because the disks were powered off. This caused Fedora to think "Oh no! Mounting file systems has failed! Let's stop right here and inform the user that something has gone horribly wrong!", which I took as a corrupted system.
Is there any way to write the entries to /etc/fstab
telling the computer that the drives should not be mounted on boot-up, they'll be mounted when I say so?

What is the end game plan for @live.co.uk email accounts now that Outlook is being rolled out to replace Hotmail? Will they still exists or will they be migrated to Outlook or what? Thanks. 92.6.144.109 ( talk) 18:58, 26 August 2012 (UTC)
I just bought a new 2 terabyte hard drive, which I'd like to transfer my entire existing Fedora 17 Linux system to. The current system is on two physical drives with a total of 4 partitions (plus a swap partition), about 800 gigabytes in total. This is becoming too small for me. How can I transfer my entire Linux system to the new hard drive? I could just plug it in, partition it with GPartEd and format all the partitions, and copy all the files across, but how do I get the disk labels right in /etc/fstab
on the new disk, and how do I create a bootloader? Would it be easier to simply do a full install of Fedora 17 on the new drive, and then copy all my old files across, either from the original drives or the back-ups I've been creating on my external Lacie hard disks? Can I just back-up the entire root (/
) partition to the Lacie drive and restore it to the new disk, but with keeping /etc/fstab
intact? It's the exact same version of the operating system, so that shouldn't pose a problem.

sudo dd if=/dev/sda of=/dev/sdb
rsync -av /mnt/old/ /mnt/new/
(which can be resumed [by running the same command again] if interrupted) to copy the data from a
liveOS. You can fix /etc/fstab
with the information from blkid
run as root (using UUID or LABEL values instead of /dev/foo is a good idea), and fix GRUB with grub-install /dev/sdX
(where X is the 2TB device name letter). You might also want to reorder the drives (by cable connections) to have your 2TB be the first device before reinstalling GRUB, if you haven't already. If you were changing more than just the hard disk (migrating the system to an entirely different computer, for example), you might also need to alter your kernel/modules for proper driver support. ¦
Reisio (
talk) 20:23, 26 August 2012 (UTC)I've been using
rsync to create back-ups of my system to my external Lacie hard disks. The man page tells me that rsync --delete
will delete all files and directories on the destination that are not found on the source. But I found out that it only works for the top level of the source and destination directories. Any files and folders in subfolders of the destination that are not found in the respective subfolders of the source are left untouched. How can I make the --delete
option work recursively?

rsync -av --delete
seems to work fine. But after I have done it once, I want subsequent calls to skip files that are already present on the destination and haven't been changed on the source. Otherwise it is going to take me hours each time, with all my about one hundred thousand digital photographs stored on both my internal hard disk and the Lacie disks. And no, the Lacie disks are not FAT32 or NTFS, they're ext3.
