I'm currently filling out a profile on elance.com for web development jobs and am being asked to indicate which skills I possess. Some of the choices include MacOSX and Windows. I've also seen people list these on resumes(used to work in HR) in the same section where they list proficiency in MS Word, or even in a separate section for operating systems, for pretty much every kind of job, not just tech-related.

I have just installed Ubuntu 12.04 LTS on a Lenovo Ideapad that was running Win XP SP3 and wish to bypass the password manager so the annoying message: "
enter password" (which I do correctly), this is then followed by "Enter password for keyring default to unlock".
I Googled this and found lots of conflicting answers but none of them work for me.
I cannot find the 'keyring manager' to leave a blank password as some suggest, so I'm at a loss and frustrated. I don't really want to reinstall Ubunto!
Please help, stating the steps one by one that I have to take.
There is this bash script that should take the contents of a log file, grep for a keyword, and then send the entire line to another script. It isn't doing that, and I'm not sure why. Can you spot the error? [more inside]

Ubuntu touch preview does not use X11 for graphics. The repository for armhf contains virtually all apps available in desktop Ubuntu, but they cannot be run directly on the tablet (Nexus 10 in my case). Is there a way to run those using a virtual X-server, perhaps passing through local VNC to be displayed? I have ssh access to the device, so I can run commands normally.
I'm trying to partition the hard drive on my old mac (model 4,1 running OS X 10.5.8) so I can dual boot Ubuntu.

I am looking into alternatives to Windows EFS to protect sensitive data on a Linux web server. I know practically nothing about EFS, but I get the impression that the files are effectively plain-text if you are logged into the Windows machine as the user who owns the files, so the same level of "encryption" exists in a Linux environment if the files have only read/write perms for file owner and no perms for anybody else. My colleague says "No, it is not the same level of security" but doesn't provide any further info regarding how/why it's different. What am I missing here? [more inside]

My friend's laptop runs windows 7. After resetting last night she's getting an Operating System Not Found error during boot. Assuming the hard drive hasn't completely failed, what are the best, simplest tools she can use to either fix the problem or at least get her important data off the drive? She has access to another computer with a cd/dvd burner, an 8GB USB flash drive, and blank cds. She doesn't have access to the system restore disc or anything like that. She can get a blank DVD if that's simplest. I was leaning toward Knoppix as the Linux distribution for a live dvd, but if there's an easier way I'd love to hear it. Thanks.
Long story short- I'm trying to make a go of it with an Acer C7 Chromebook as my main computer. I installed ChrUbuntu, and this is my first foray into the world of Linux. I like it so far, but it does beg the question of what to do with backing-up/restoring my iPhone 4s and iPad (original). Pretty soon I'm going to want to unlock my iPhone so I can switch to a prepaid plan, and I understand you need iTunes for that. Is there a Linux workaround that anyone knows about?
my computer froze, and when i tried to reboot it, it got to the green suse screen proceeded normally, and then when it went forward, i got an error message that said could not start "kdeinit4. check your installation" tried to fix it using the protocal i found here but sitll have the same problems with the error message. I hadn't plugged in my computer for about 5 months, because I had a laptop, but the laptop is on it's last legs, but it was working pretty well for the last couple of days.

I have a mess of ad-hoc backup systems, none of which “just work”. I would like to have a NAS that quietly backs up the cross-platform content I have, and also mirrors it online securely.

I have an Acer laptop with an i3 chip and the standard amount of RAM, probably 4GB that I bought in 2011. Just over a year after I bought it, and just weeks after the end of warranty, the hard drive died. I'm wondering how hard it would be to buy a new hard drive and install Ubuntu or something like that. Is it possible? If so, how much of a pain is it to set up drivers? Would I have to manually install drivers for nearly everything (USB ports, wireless receiver, etc)?
I lease a massive server that I am underutilizing. I'd like to use up to 8TB/month of transfer and 500GB of disk space to make the world a better place. I am already seeding Ubuntu distros, Project Gutenberg, and Pearl Jam shows, and I'm looking for more ideas.

I bought a new laptop that has 2 hard drive bays. It came with a hard drive with Windows 7 preinstalled. I bought an SSD, installed Windows and Linux fresh onto it, wiped the old hard drive and used it as a data disk, but something is slightly out-of-whack in the boot sequence (and a partition is marked "System" when it really isn't). Is it worth fixing? [more inside]

Using a laptop running Ubuntu Linux 12.04, I want to record three things at once: 1) video of my desktop, 2) video from a USB webcam, 3) audio from a USB microphone. Ideally I would like some setup which simultaneously starts all three recordings, and keeps them in sync, so that it will not be too painfully difficult to mix them later -- my eventual aim is to make a kind of "picture-in-picture" screencast. Is this feasible, and if it is, what's the best approach? (Free is nice, but if I can make this process smoother by paying less than a thousand dollars, I will happily pay.)
