Firefox Aurora and Mozilla Thunderbird
i had the browser, Aurora, for quite a few weeks and everything was running well. then i downloaded the email client, Thunderbird. after the installation, it asked me to restart my computer, so i did. but on restarting, i found out that Aurora is gone, i couldn't find any file of it anywhere. there were just the shortcut icons left on my start menu and desktop which said on double-clicking "file not found. delete shortcut?". i, obviously, clicked on ok and deleted those pathless shortcuts. but where did Aurora go???? and another thing. when i tried to add an email account to Thunderbird, it asked me my name, email id and password. i entered everything correctly, i established the incoming connection as IMAP and outgoing connection as SMTP, i even went to my gmail account and turned on the IMAP settings. but, Thunderbird says that there's an error in server sign-up connection or something like that. simply put, it can't be connected. same thing happening with chat account (i've tried with both facebook chat and gtalk)

WHAT THE HELL IS WRONG WITH MY COMPUTER??? :(

 * Just a guess, but perhaps the email client required an updated version of the browser, and the update process involved removing the old version first, but the process died before the new version was installed. I'd look on your desktop for an install icon, as many download managers leave one of those, especially if the install is aborted.  If not, then just start the process over.  If it still doesn't work, try a different browser and/or e-mail client. StuRat (talk) 14:25, 15 February 2013 (UTC)

 * I don't understand. In what context ?  Do you mean train cars which join together automatically when pushed together, or something else ? StuRat (talk) 14:02, 15 February 2013 (UTC)
 * A Google search shows that all the results are about Higgs Boson. Wrong RD, perhaps? Kayau (talk · contribs) 10:48, 16 February 2013 (UTC)

[Ubuntu Question] "target is not a directory"
I am attempting to follow this man's instructions: http://steamcommunity.com/app/221410/discussions/0/846939854078934188/#c846940248596940111

Sadly, I am stuck on step 5; after making the new directory (I also used/Steam_Files) it informs me that 'target `/Steam_Files/' is not a directory."

But I just made that directory. Where is my mistake? --Ye Olde Luke (talk) 08:42, 15 February 2013 (UTC)


 * What syntax did you use to make the directory? What happens if you try cd Steam_Files ? --Phil Holmes (talk) 11:15, 15 February 2013 (UTC)


 * Did you use mkdir to create the directory ? StuRat (talk) 14:21, 15 February 2013 (UTC)

SVG export from MathJax
Is there any way to copy an SVG render from MathJax to a separate file, and declare or remove the external dependencies, that's ever easier than rendering via TeX? I've tried copying the tag using Chrome's Developer Tools, pasting into a text editor, and adding the usual  and <!DOCTYPE>. But then the fonts are missing, and for the expanded-form example at Hessian matrix that makes everything but the fraction lines disappear. Neon Merlin  09:56, 15 February 2013 (UTC)


 * I tried a simple example and got it working if I added  xmlns="http://www.w3.org/2000/svg"  to the SVG tag. -- Finlay McWalterჷTalk 19:32, 15 February 2013 (UTC)
 * No, never mind that; it wasn't the MathJax part of the example I was working on that I got rendering, but another SVG overlaid on it. -- Finlay McWalterჷTalk 19:53, 15 February 2013 (UTC)
