What is there in an Operating System other than the kernel
As I understand it, the kernel does all the interaction with the hardware, and manages the memory, the I/O devices, etc. So the kernel is doing everything, yet it is just a part of the operating system. So what else is there in an OS ? Just the applications that come bundled with it ? For example, what does Ubuntu have other than a kernel ? The Gnome Desktop, and a few other applications ?
How do you disable the window switch animation when switching spaces with Mission Control?
In Snow Leopard, I had the window switch animation disabled when I quick-key between spaces. Now that it's Mission Control in Lion, there's a long animation during which all my desktop icons disappear and I can't use anything. I'd really like to disable this, but the old fix doesn't appear to work. How can I disable this needless animation in OS X Lion or later?
Is it possible to sign a file using an ssh key?
I use SSH (OpenSSH 5.5p1 on Linux, to be precise). I have a key, on which i have a passphrase. I use this for the usual logging in to computers stuff. Can i also use it to sign files? As i understand it, an SSH key is an RSA (or DSA) key, and during the SSH login process, it is used to sign messages sent to the server. So in principle and in practice, it can be used to sign things - indeed, that is its sole purpose. But as far as i can see, there is no way to use the key to sign an arbitrary file (as you would with PGP, say). Is there some way to do this?
Does All LAN Traffic Travel Through A Router
I have a very simple question: if I have a router (DHCP enabled - leasing IP addresses between and ) with a switch plugged in, and I plug two computers into the switch, will the network traffic (file transfers etc.) be sent through the router, or will it simply go straight through the switch to the other computer completely avoiding the router?

Install libpq-dev on Mac OS?

Bash completion for commands in Mac OS X

Holding Ctrl and B followed by another command key usually gives me nothing. I have no file so I'm not overwriting it.
Is it possible to mount a .tar file?
The only result of any import when I searched for this was from 2001. In the intervening decade, have any tools/methods for mounting a tar file as a filesystem (perhaps utilizing fuse) been created? If so, what are they, and how do they work?
How to use wget to download HTTP error pages?

Get mac tar to stop putting ._* filenames in tar archives
Possible Duplicate: Why do I get files like ._foo in my tarball on OS X? I create autoconf scripts on a Mac. When tar runs, it puts all of these ._foobar names in the archive: Now what's going on is the Apple's HFS filesystem is putting the file properties in the ._foobar names so that they can be restored on another Mac system. But I don't want them --- they are just junk for me. Is there any way to suppress them?
Lightweight CSV viewer for Mac?
I need to view (large) CSV files on my Mac. I could use something like OpenOffice, but unfortunately it's pretty big and slow. I'm wondering if there's a Mac equivalent of some of the Windows tools mentioned on this SU question.

Automatic SSH tunneling from Windows
I'm trying to set up a Windows computer to always have two SSH tunnels to my Linux server. Currently, I'm using PuTTY to open the two SSH tunnels: I log in to the server in PuTTY, leave it minimized, and never touch it. This works well, except when the SSH connection drops: PuTTY displays an error message, and I need to manually close the error and reconnect to the server. What I'd like to do is have an application that can set up the two SSH tunnels, and can automatically reconnect, without needing to manually do anything, including enter a password. The data I'm sending across the two tunnels is VNC connections, so I often won't be at the machine to clear errors and enter passwords. The two tunnels are one local tunnel, and one remote tunnel. (Yes, I am aware of the hazards of automatically logging in to SSH. I'm planning on making a dedicated user with no privileges and not allowed to interactively log in, and use that.) I did find this question: How to reliably keep an SSH tunnel …
How to clean up output of linux 'script' command
I'm using the linux 'script' command http://www.linuxcommand.org/man_pages/script1.html to track some interactive sessions. The output files from that contain unprintable characters, including my backspace keystrokes. Is there a way to tidy these output files up so they only contain what was displayed on screen? Or is there another way to record an interactive shell session (input and output)?
Maximum resolution through VGA/DVI/HDMI(/etc)?
I know the original VGA standard was meant to output 640x480 and that other standards over the original VGA connector are developed to output a higher resolution. (SVGA, XGA, etc.) But I was wondering if there's a specific limit to the resolution that the VGA connector can take. Furthermore, are, and if so how are for example DVI and HDMI limited on resolution?

How do I install a font from the Windows command prompt?
Is it possible to install fonts from the command prompt on Windows? If yes, what is the command? I tried and it said copying was complete, but I could neither find the said fonts in the Fonts folder nor find them in the font list of any program so that certainly didn't work. (Although I was able to delete the said fonts from the Fonts folder afterwards)
