[edit] March 31

[edit] Can I have a file and Web server on one server?

Can I have a file and Web server on one server? I want to do this because it's cheaper than having two server for that purpose. Jet (talk) 00:17, 31 March 2008 (UTC)

Yes, of course. There's nothing special about "server" software, it's just a daemon that listens on a network port. You can set up vsftpd listening on 21, sshd on 22, httpd on 80.. you have ports up to 65535 to work with on one IP bind so you can run pretty much as many different daemons as you want. Better, kushal? :D\=< (talk) 01:13, 31 March 2008 (UTC)
You can, but it might be a bad idea. Servers often are separated by function for a good reason. A problem on one application could cause problems with the other function. For example, the disk on the file server could fill up and crash your web server. Are these mission critical applications, or does no one really care if there are occasional problems? What is more important uptime or cost of a new server?

[edit] Transfering iTunes library

I've just gotten a laptop, and I've been transferring my iTunes library to it using DVDs and the backup system that iTunes features. It's worked OK, although I've lost about 100 songs (out of 7200) somewhere. I'll track them down eventually, but my immediate concern is that, while all the metadata such as lyrics and album covers transferred OK, none of the playlists I've created did. Redoing the smart playlists won't be difficult, but I also had playlists based on record label, and it's going to be a pain to redo those. Any ideas would be appreciated. --Joelmills (talk) 00:20, 31 March 2008 (UTC)

Make a separate disk with your playlists saved on it? :D\=< (talk) 01:06, 31 March 2008 (UTC)
iTunes has a special folder where it stores all of its data (SOngs, album pictures, playlists). If you can somehow transfer that folder and its contents from one computer to another, your problem will be solved. —Preceding unsigned comment added by 68.127.62.211 (talk) 04:14, 31 March 2008 (UTC)

[edit] How does this URL work?

Saw this in my spam in an old old gmail account:
http://0xcb.0x5e4e82
Click it, it actually works. What the heck? Don't give them your login if you're really in the Sri Lankan air force though, it's obviously a phishing site. :D\=< (talk) 06:23, 31 March 2008 (UTC)

The requested URL could not be retrieved
While trying to retrieve the URL: http://0xcb.0x5e4e82/
The following error was encountered:
Unable to determine IP address from host name for 0xcb.0x5e4e82
The dnsserver returned:
Name Error: The domain name does not exist.
Not for me... --antilivedT | C | G 06:52, 31 March 2008 (UTC)
The hex corresponds directly to the IP address (203.94.78.130) so maybe something in the handling of URL's in browsers? --antilivedT | C | G 06:56, 31 March 2008 (UTC)
(After edit conflict) It's just 203.94.78.130 written in hexadecimal with fewer dots. 0xcb is 203 and 0x5e4e82 is 94*256*256 + 78*256 + 130. Other equivalent forms:
0xcb.0x5e.0x4e.0x82
0313.0136.0116.0202 (octal with leading zero)
3411955330 (yes, http://3411955330/ is valid)
Another interesting rule is illustrated by "10.1", meaning 10.0.0.1. Zeros fill the missing octets.
If you find that some or all of these don't work, it's because some recent software has been specifically designed to reject them, because their use is almost always part of a fraudulent enterprise such as the one you mentioned. --tcsetattr (talk / contribs) 07:01, 31 March 2008 (UTC)

Server not found Firefox can't find the server at 0xcb.0x5e4e82. * Check the address for typing errors such as ww.example.com instead of www.example.com * If you are unable to load any pages, check your computer's network connection. * If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Not for me either. Kushal 12:16, 31 March 2008 (UTC)

It all depends on what your IP Stack and browser. See IPv4#Address_representations for an explaination of the IPs. Some browsers have been patched to not allow non-dotted-digital IPs because they're often used to obfuscate an otherwise dangerous URL. -- JSBillings 15:49, 31 March 2008 (UTC)
Thank you very much, JSBillings. The information was very useful. I really appreciate it. Kushal 22:34, 31 March 2008 (UTC)
Another scam which used to work was http://gmail.com:sometexthere@example.com/ (same as http://username:password@example.com ) -h2g2bob (talk) 23:30, 31 March 2008 (UTC)

[edit] Transfer files phone -> laptop

How do I transfer photographs (.jpg) frohttp://en.wikipedia.org/skins-1.5/common/images/button_sig.pngm my phone (Samsung D900i) to my laptop (Compaq Presario V6500 with Vista)? I've tried checking for external drives from the list and bluetoothing (I've got a USB plugged in). Any help would be appreciated as I have lots of pictures for a Wikipedia article. George D. Watson (Dendodge).TalkHelp 16:23, 31 March 2008 (UTC)

Vista Home Premium to be exact. George D. Watson (Dendodge).TalkHelp 16:38, 31 March 2008 (UTC)
That phone supports Bluetooth, a memory card (MicroSD?), and probably came with a USB cable in the box (for which you will need to download PC Studio from Samsung's website); so it seems you have plenty of choices. In my experience, Bluetooth is too slow, and the PC Studio software is pretty clunky, so my personal preference would be to ensure the photos are on the memory card, then take it out and put it into a card reader connected to your PC so you can drag 'n' drop the photos. Astronaut (talk) 18:01, 31 March 2008 (UTC)
Modern Bluetooth is fine for JPEG images. Even 2MP images are only a couple hundred Kilobytes. If you were running a Mac, you'd fire up Bluetooth File Exchange and just drag and drop images from your phone to your desktop.
I use a free program called BitPim which allows me to download and upload any file to and from my phone. It supports a very large number of phones, if I remember. — Mike 20:34, 1 April 2008 (UTC) —Preceding unsigned comment added by 63.138.152.238 (talk)
On my phone, I love using the MicroSD card. It makes it real easy to transfer files from the phone to the PC and also put photos I have on my phone. You also get a lot of storage that way. If you go this route, you will have to copy the file from the internal memory to the MicroSD card. On my phone, "Copy file to flash" is a menu option when you look at a photo on the phone. You can probably set up your phone to automatically save new files to the external card, but it sounds like you already have some photos on your phone you want.--Wonderley (talk) 19:23, 2 April 2008 (UTC)

[edit] free cross-platform software that will save form data in PDF files

Is there a free, cross platform software that would allow me to save data in a fillable PDF file (such as this one) just as Adobe Acrobat Standard or Professional does?

Thank you very much. Kushal 22:39, 31 March 2008 (UTC)

This says Scribus can. -- Finlay McWalter | Talk 12:56, 1 April 2008 (UTC)

Thank you very much. I am already reading the "Getting Started [...]" page now. Thanks once again. Kushal 17:03, 1 April 2008 (UTC)

[edit] Wordpad problems

I was typing a report on Windows XP Wordpad. When I went to open it up, there was a line through the words. I tried changing the font, coping and pasting the words back in, and opening the document in a different non-Windows program (Abi Word Portable) and the line was still there. How do I get rid of the line? —Preceding unsigned comment added by 24.151.127.188 (talk) 23:55, 31 March 2008 (UTC)

It sounds like you've accidentally turned on strikeout. Try selecting the text, going to Format > Font and unchecking Strikeout under Effects. On my machine, Wordpad is quite picky about when it shows the Effects options (might be a bug), so try getting rid of the strikeout in Abi Word Portable. Not sure where the option is, but it's probably in a similar place. — Matt Eason (Talk • Contribs) 00:09, 1 April 2008 (UTC)

On Wordpad, there was no "Effects" under font, and Strikeout didn't work on Abi Word. —Preceding unsigned comment added by 24.151.127.188 (talk) 00:35, 1 April 2008 (UTC)

Just to make sure, please follow some simple instructions. Please copy and paste the text to Notepad. Then, (at your option) save it as an ordinary Text file. Now copy the text from this document and paste it in a new Wordpad window. Could you report back your results here? Thanks Kushal 04:07, 1 April 2008 (UTC)
