  1. I have no idea. I've never had any reason to learn how to troubleshoot USB. Anyway, if it is a kernel issue, you'd probably have to replace the kernel to fix it. If that's not option, I'm not sure what you could do even if you knew the cause.
  2. From what I gather, it's usually caused by USB controllers (and possibly devices) disconnecting for whatever reason. However, I think there have been kernel bugs with similar, if not identical, symptoms and since it's easier to deal with the kernel than defective hardware, I'd start there. So, try a different kernel. Probably the easiest way would be to grab a live CD of a very up-to-date distro.

  4. It's Chrome OS this week. It was Android a few months ago. I'm not sure which I'd want less.
  5. AV vendors would release software for rocks if they thought people would pay for it.
  6. This process also works in reverse. Still, the iPad is the only tablet I've seen that I'd even consider paying for.
  7. Assuming the old machine works (at all), has rsync installed, and the new drive is mounted under /mnt: # rsync -aHA --exclude=/mnt/ --exclude=/dev/ --exclude=/proc/ --exclude=/sys/ / /mnt should create a copy of the entire system, sans excluded directories, under /mnt/. You might have to fiddle with the options a bit to get exactly what you want. If you're sure that everything you need is under /etc, /home, and /var, you can --exclude everything else or just rsync each of those directories individually: # rsync -aHA /var /mnt # rsync -aHA /etc /mnt # rsync -aHA /home /mnt Note that leading a

    Qt Help

    rID = http.get("/index.html",pdev); pdev is null here, so http returns the data via signals. You need to move QTextStream stream(&file); pdev = stream.device(); above the call to QHttp::get() or just pass file to get() instead.
  9. WANT! But can't have without a Linux- or Windows-based SDK.
  10. Dunno. Probably in the neighborhood of 50 MiB/month.
  11. I pay $6/month for unlimited data and tethering on T-Mobile. I think I'm glad I don't use AT&T or Verizon.
  12. There are no HTML/CSS certifications. No, wait, never mind, I'm sure there are. Probably dozens. Damn it.
  13. If you're using Compiz, you might be able to force the window to the desired position using the Fixed Window Placement settings from the Place Windows plugin.
  14. If the file was unreadable, I'd expect an open error or read error instead of a parse error. It sounds like it's corrupt.
  15. First thing I'd do is log out, log back in, and check ~/.xsession-errors and the system logs (/var/log/Xorg.0.log -- really, everything under /var/log/) and see if X or the NVIDIA driver are complaining about anything. If there's nothing in the log, you could flail around a bit. Three approaches come to mind. (You don't have to log out while you're doing any of this, but you do have log out and back in for the changes to take effect.) First, you could move (not copy!) your xorg.conf somewhere safe (I usually just rename it xorg.conf.bak) and then run nvidia-xconfig as root to generate a fresh
