I have an old laptop (working) with a screen that was disassembled. The silvering on the last layer of the LCD unit was washed off and now the screen is impossibly dark. Can this be replaced with aluminum foil or something similar? 76.117.247.55 ( talk) 03:30, 3 April 2010 (UTC)
In the RGB color model, what is the range of numeric representations for normal human skin? For the purpose of this question, I am counting congenital albinism, natural sun tanning, and aging as normal. Artificial treatments are not counted. -- Wavelength ( talk) 05:57, 3 April 2010 (UTC)

Unfortunately, RGB is inherently uncalibrated, and human perception of computer RGB colors can be strongly affected by monitor characteristics, ambient lighting, etc. so your questions are not really all that meaningful as they stand. There's sRGB, a standardized version of RGB, but there's no guarantee that your system is sRGB-compliant unless you've carefully calibrated your monitor in one particular set of ambient lighting conditions, etc... AnonMoos ( talk) 06:28, 3 April 2010 (UTC)
If you are contemplating using these RGB numbers for computer graphics - I've gotta warn you that they won't do you much good. Drawing things in "skin color" doesn't produce reasonable results because the things that make for realistic skin have little to do with color. With good lighting algorithms, you can make green skin look "real" but without good lighting, even getting the RGB values perfect for your own skin won't produce good results. When drawing skin, you need to pay a lot of attention to surface texture (tiny pores, etc), to the shininess (which varies over the skin with oily deposits) and especially to an effect called "subsurface-scattering". If you get those things right, then the range of believable colors are truly vast. SteveBaker ( talk) 16:42, 3 April 2010 (UTC)
Thank you all for your answers. -- Wavelength ( talk) 14:47, 4 April 2010 (UTC)
What do you call a single .c file within a multiple file C program (and its header file)? Is it a "module"? (Never mind whether it's truly a module - is that the term generally used?) 213.122.26.30 ( talk) 07:38, 3 April 2010 (UTC)

(
talk) 13:07, 5 April 2010 (UTC)I'm having serious problems. I'm on Wichita State University's guest network, and I'm having trouble (despite a full wireless signal) getting the internet to function. I ran a few diagnostic tests, and they told me
“ | The wireless router/AP for your network is either unavailable, not working, or is disconnected. You will not be able to connect to the Internet, although you might be able to connect to your local network. | ” |
I'm lucky to have gotten to here to ask how to fix it, as it took me 45 minutes to get the connection to function long enough. Web pages will load partly, then not finish loading or will not even start loading and return the "Connection timed out" error. All of this is happening with a full and strong signal. I may, if I'm lucky, get a small burst of .5% network utilization. What's going on with this connection, and how do I fix it? -- Ks1stm ( talk) alternate account of Ks0stm 14:04, 3 April 2010 (UTC)
User Services Helpdesk
The User Services Helpdesk is one source of contact for information, to report technical problems, and to dispatch assistance.
Contact Information
The Hours of Operation are Monday-Friday, 8:00am to 5:00pm. 3 WAYS to summon HELP 1. Call WSU-HELP (978-4357) 2. Fill out an Information Request Form 3. email helpdesk@wichita.edu Always provide the following: * Name * Phone number where you can be reached (Land line preferred) * Brief description of the problem We will respond as quickly as possible. Every call and on-line request is important. These requests are logged and prioritized based on the problem. While every effort is made for a quick response, demands of time and resources may result in delays of service.
So in Windows 7 you can scan a drive for errors. But I have a folder where I know there's an error (because every time I try to open it, I get an error) so can I just scan that one folder instead of scanning the entire drive which is take hours? —Preceding unsigned comment added by 82.44.54.207 ( talk) 15:13, 3 April 2010 (UTC)
I often use the "solid compression" option in rar and 7zip because I'm compressing many thousands of similar files, many of which are over half the same exact data in each of them with only a few tiny changes here and there. Because the files are so similar, the solid compression gives great space saving results. I was wondering, does something similar to solid compression exist but without the actual compression part? For example a way to store many similar files by scanning them and only writing a set of data once instead of saving the same data over and over for every file that has it? I hope that makes sense. —Preceding unsigned comment added by 82.44.54.207 ( talk) 15:53, 3 April 2010 (UTC)

Hi. There's a website using Joomla, with a http://resources.example.org subsite (also using Joomla), but in order to access any of the documents, you need a password. Their office won't be open until Tuesday; is there anything I can do in the meantime to intiuitively work out the download URL? Thanks! ╟─ Treasury Tag► duumvirate─╢ 19:50, 3 April 2010 (UTC)
When I tell Firefox to print the webpage I'm looking at, it only sends the beginning of the webpage, the part that is visible in the browser window without scrolling, to the printer. It does not send the remainder of the webpage, that you would have to scroll down to see, to the printer. All three versions of Firefox that I've used have done this. How can I fix this problem please? Internet Explorer, when looking at the same webpage, prints the whole page and does not have this problem. Thanks 84.13.45.122 ( talk) 20:12, 3 April 2010 (UTC)
Yes, I am sure. 89.243.37.199 ( talk) 22:18, 3 April 2010 (UTC)
It does print OK for some pages. It does not like printing all the search results obtained from this page http://www.gassaferegister.co.uk/ after entering a postcode. I get one page with two blank pages. I found this: http://kb.mozillazine.org/Problems_printing_web_pages but nothing jumps out at me as being a solution - perhaps an expert would understand more. 89.243.37.199 ( talk) 23:18, 3 April 2010 (UTC)
Hi all - having problems burning some files (I believe they are CDG files) from my computer onto a CD-R. The files all play fine on windows media player on my computer. When I burn them on to CD-R the files all burn fine but when I try to play them in my karaoke machine the song counter starts counting as if it were playing a song but there's no sound - and yes the volume on the player is turned up! The files are compressed - does that make a difference? Cheers. RichYPE ( talk) 20:52, 3 April 2010 (UTC)
Don't think the files are copyrighted, I paid to download them from a karaoke site so should be able to burn them to a disc. Thanks for the link to the website - I have identified the problem - my compact disc has folders on it. I take it I need to change the way my computer burns, so it burns to audio CDs. How do I do this for windows XP? Thanks RichYPE ( talk) 17:57, 4 April 2010 (UTC)
Thanks to Bavi for the response - does anyone know the name of the software I need? Thanks RichYPE ( talk) 20:13, 6 April 2010 (UTC)
