I remember being in a computer lab once that employed quite a clever tactic for the public terminals. The user would log in with an assigned username, and then when the user logged off, the *entire* hard drive would be wiped away and over-written with a fresh copy of the operating system (windows) as if it had just been installed the first time (default configuration). Every user who logged in was shielded from anything put on the comp by any previous users. This was a way to get rid of all unwanted stuff installed by the user or otherwise.
How can I do this on my home computer? I'd like to install a 'default config' and then do a rollback everytime I log off. I've seen some pre-packaged stuff, but it is all half-assed and bloatware. Is there a 'freeware' way to do this? Not against programming it myself if necessary, cause it seems like a great idea. Also, does this strategy have a name? NoClutter 01:03, 28 January 2007 (UTC)
The name for what you want is disk cloning, often referred to as Ghosting. Ghost is not free, but there are links to numerous programs in the former article and one of them may be what you want.- gadfium 03:41, 28 January 2007 (UTC)
Is there a way to set up a USB hard drive so it is always guaranteed to get the same drive letter no matter what computer you attach it to? It's annoying when links and shortcuts dont work and get 'resolved' into an incorrect location just because a particular computer I'm using is already using the Drive letter I had been using before. This would be a huge annoyance-buster if it is possible. NoClutter 01:15, 28 January 2007 (UTC)
I have a series of buttons on top of each other in a side navigation bar. I would like to simulate a javascript rollover, but with CSS. The buttons are images and I would like the button to change from the first image to the second image when my mouse if on top of it. What would the CSS and HTML codes neccessary to achieve this? Thank you. Jamesino 03:31, 28 January 2007 (UTC)
I'm writing a small Java bit which needs to POST some information to a web script and catch the result. Here's the Perl I want to port to Java.
my $req = HTTP::Request->new( POST => $self->{base_uri}."/relay.php/${method}" ); $req->content_type('application/x-www-form-urlencoded'); foreach my $param (@params) { push @p, "param${count}=${param}"; $count++; } $req->content(join('&', @p)); my $result = $self->{ua}->request( $req );
Is there some small piece of Java I could use? Something in the standard toolkit? Something I don't need to import 500k of JARs or write a whole library of my own for? grendel| khan 04:54, 28 January 2007 (UTC)
URLConnection
or something like that. --

HttpURLConnection.setRequestMethod(java.lang.String)
might come in handy here. Thanks!

khan 08:33, 28 January 2007 (UTC)It would be really cool if a program is available that could generate animations of chalkboard drawings being drawn based on user-inputs. In the event that one does not exist or cannot be found, how can this be done in Flash? I would really like to do this some way. Just unicode characters are okay too. Any way this could be done (especially if on Mac OS X :) ) would be much appreciated!

How hard is it to convert audio cassettes to DVDs (I have XP Media Center Edition 2002)? Does it require any special software/hardware? The quality doesn't have to be great - adequate is fine. Clarityfiend 07:53, 28 January 2007 (UTC)
I read in an old computer palmphet about something called a "mouse pad". What is a mouse pad and why would a mouse need a pad to work? 58.157.241.42 08:07, 28 January 2007 (UTC)

My computer is networked with 2 other computers wich share the same ip address and the same internet service internet explorer if i was to use my free 6 month trial aol 9.0 disk and use aol would my ip address change?if so how often? will it happen more than once? and will my computer still be networked with the others?-- Crocadog 13:48, 28 January 2007 (UTC)
On one account on my computer, I deleted unused icons because that account was mostly used for playing games, so I moved most of the icons that were unneeded like MS word, etc into a folder on the desktop. But now on the other accounts, those icons just dissappeared. How can I get them back? 67.169.56.188 18:29, 28 January 2007 (UTC)
What are the pros and cons of CSS rollover buttons vs Javascript rollover buttons? For example, which one loads faster, which one is more supported by browser, etc... Thanks. Jamesino 19:13, 28 January 2007 (UTC)
I have created a little Flash movie which works fine when I view it with Safari, Firefox on OS X, and Internet Explorer on Win XP. But in Firefox on Win XP (same computer I tested it with IE) none of the text objects load correctly. The font isn't obscure, it's Arial. What could be causing this? Note again that it loads fine in IE on the Win XP machine, but not Firefox. (Firefox v.2) Thoughts? Work-arounds? -- 24.147.86.187 21:02, 28 January 2007 (UTC)
Cheats, hints, anything for the game "Drift: When Worlds Collide"?
Any level skipping cheat or anything else would be helpful. Especially how to get past level 10. Thanks! Trying to get past the level today! 71.85.0.61 18:05, 28 January 2007 (UTC)
I have a Java object, which may be a String, an int, a Map or an array, and I want to turn it into a JSON string. I've looked at some JSON libraries, but they all seem to center around parsing JSON strings into internal Java representations, which isn't what I want. I want it to construct a JSON string out of an arbitrary Java object. How can I do this? The Perl objToJson() method in the JSON package does exactly what I need. But this toJSON() method, for instance, chokes if I pass it a String which isn't already JSON-formatted. I end up in a chicken-and-egg situation. Do I have to write my own JSON library at this point? grendel| khan 00:40, 29 January 2007 (UTC)
